Book Company, Inc. r AUTOMOBILE REPAIRSHOP SHORT-CUTS HI t re I 9 S PREFACE I F a motor car repairman could go through more than one thousand of the best garages and repair shops in the United States and collect the good ideas he saw in them, he would have a wonderful fund of information on which to draw in solving the problems that come up from day to day. Realiz- ing that few mechanics or garagemen have that opportunity, however, Motor World employed a corps of trained investigators to obtain that very information. In their tour of the country these experts visited more than one thousand garages, repair shops and service stations and collected several thousand time and labor-saving kinks, methods and devices which the various shops they visited have found exceptionally helpful in making ^ engine clutch, gearset, running gear and body repairs, in manag- ing and equipping these shops, etc. Fifteen hundred of these were picked out after a careful study of the entire lot and these are given in the following pages. Mere gimcracks and novelties that have no practical value have been omitted. The idea through- out has been to give helpful suggestions that will shorten the time in which a job can be done, or show a better way to do it. While the book unquestionably makes interesting reading for an evening by the fire, it is really intended for constant ref- erence at the shop and we recommend that you keep it there. Its contents have been collected at considerable expense and with the sole thought in mind of helping the good mechanic become a bet- ter one. Progress comes largely from experience. And here is the experience of fifteen hundred experts who found that the par- ticular method they explained was a better way to do some job IV AUTOMOBILE REPAIRSHOP SHORT-CUTS PREFACE— CowfeViwefl? or helped them shorten the time required to do it. A glance at the special index given in the front of the book will enable you to locate any item at once. These methods were first published in Motor World as "The Repair Shop Short Cut Department." Garagemen and repair- men immediately realized its great value and the Department proved a phenomenal success from the very first. In fact, it was so popular that the issues of the paper were soon exhausted and the demand for them was so insistent that it was finally decided to publish all of the data in book form. That was done, but the edition was quickly exhausted. A second and then a third edition was printed, but these were also rapidly exhausted. This is the fourth revised and enlarged edition. It contains all of the short cuts which appeared in previous editions, as well as some six hundred additional kinks which have subsequently appeared in Motor World. The publishers will be glad to receive criticisms or sugges- tions from interested readers. If you have a method of doing some particular repair which you think is better than any shown in this book, let us know about it.

The removal of the sediment every dar from the tub keeps the oil clean enongh for the purpose and only enough need be added to make up for evaporation and other slight losses. When the tub is not in use it is kept in a wooden box with a cover, which is closed, excluding dust and providing protection against ignition. By this method time is saved, kerosene is saved and the appearance of the shop is saved. A very convenient fart of the outfit is a box for moving the parts to the cleaning tub and back to the car; the box is 5 feet long, 3^ feet wide and i foot deep and is mounted on castors There is a small compartment for small parts and a large compartment for heavier components. — W.

The jig has a di- ameter nearly equal to the swing of the lathe and is bolted to a face plate, whtcli takes the place of the regular face plate of the lathe. The jig is made in two pieces, all but the front cover being one casting, and the front cover another casting. The cyl- inders, whether cast singly or in pairs, are inserted through one of the open- ings in the side of the jig and the cylin- der flange is bolted to the front cover. After the cylinder has been accurately centered, the boring tool is inserted, or if the cylinders are to be ground a special grinding fixture is put into operation. Such a fixture can be obtained from al- most any of the lathe manufacturers and a number of types and sizes are avail- able.— W. F. Green, foreman, J. W. Mason Motor Car Co, Newark, N.

One way of obviating this trouble is to use the two clamps aoown herewith. One set must be made for each make of car, but since they consist only of flat pieces of iron bent at right angles at each end, there is small ob- jection to this.

Press Made of Odds and Ends in the Shop (No. 6) A satisfactory press can be made from odds and ends around the shop. There •re many ways of making such a press, and one is illustrated herewith. A 14- inch structural steel I-beam was used as the foundation, if such it may be called. Four i^-inch holes were drilled in it at the corners of a 12-inch square, and four ■teel bars about 2 feet long and threaded at each end were attached as shown. Then a cast iron plate 16 inches square and about 1^ inches thick was similarly drilled and placed over the tops of these bars. In the center of this plate a 2-inch ■crew was placed. The upper end of this screw was squared to take a large wrench. — ^T. A. E. Wilson, Ossining Gar- age, Ossining, N. Y.

Recently we saw » pile of at least 2,000 used screws, nuti and washers spread out in one comer ordinarily di of a crowded work bench. Whenever a mechanic wants a part from this pile he hunts until he finds it, and it is like looking for the proverbial needle. The idea of saving these small parts is ex- cellent, but more time is wasted in look- ing for desired parts than is saved by not buying new ones. A box divided into small bins solves this problem. Whenever a piece of mechanism is dismantled and there are screws, nuts and washers for which there is not immediate use, they should be sorted into this box. 1 4 1 Dumbwaiter for Transporting Stock that of putting pU- tons into a motor witli detachable cyl- inder heads and integral crankcase in< stead of integral cylinder heads and >ep< arate crankcase. Various means hare been devised for slipping the cylinders over the pistons in the latter case, but an extremely simple way presents itself when the heads are removable. In this case the pistons are taken out through the head and replaced in the same way, therefore 'what could be simpler to pre- vent the rings from catching on the edge of the cylinder bore than the casting shown herewith. The lower part is the safue diameter as the cylinder bore, but the upper end flares out so that the piston with the rings in place may be easily inserted in it. The device is then placed over the cylinder and the piston pushed through, and thus the rings are automatically compressed and the piston is in its place in a few seconds. A great deal of time is saved by this simple device, and the piston is not harmed. Where only a screw driver is used the piston rings are often marred, the workmen skin their fingers, and a great deal of time is consumed. One casting must be made for each different bore, but where the majority of repairs are made on a single line of cars, which is generally the rnle when the repairshop is run in connection with the agency for some car, it will be found that a great deal of time will be saved by the ttse of this sleeve.

For example, a certam exhaust valve spring 4 inches in length, requires a pressure of 50 pounds to reduce its length to 3>^ inches. If a test shows that it takes just 50 pounds to compress it Vi inch the spring is all right. A device for testing spnngs consists of a spring balance to which is attached a cradle in which the spring is placed. One part of this cradle ia hooked to the spring balance and the other part is fastened to a hand lever; the spring is placed between these two parts so that by pressing down on the handle the it is compressed, and the amount of compression is registered in pounds on (he balance.

AUTOMOBILE REPAIRSHOP SHORT-CUTS Gasoline Sprayer for Cleaning Motors (No. 26) The quickest wa^ to clean a motor is by spraying it with gasoline or, pre- ferably, because of danger of fire, with kerosene. The apparatus costs practically nothing as the requisites consist of scraps of copper tubing, some rubber tubing and a compressed air supply. The outfit is illustrated herewith. The rush of air causes a vacuum in the gasoline pipe >o that the gasoline or keroiene is drawn up and is mixed with the air to form a fine spray. This mixture Is dis- charged with sufficient force to quickly dislodge any dirt adhering to the motor. The air pipe is 5/16-inch copper tubing and the gasoline or kerosene pipe is 3/16.

Garage Jack That is Not Easily Upset (No. 28} Few garages have jacks that are cap- able of lifting heavy touring cars and truck) and holding them safely while a man pulls out the axle. Generally when this sort of a job is to*be done the car is jacked up and then small horses or blocks are slipped under. The work- man is afraid to trust the ordinary jack since it is rather unstable and may al- low the car to crush him. To meet these objections the heavy jack with broad base, shown herewith, was built. The lower end of this jack is 1 toot square. The screw is 1^ inches in diameter and 6 pitch. There is a slot cut in it so that it will not turn. The shape of the upper end of the jack is peculiar and is also designed with a view to extreme safety. . A hardened piece of steel tapered to a fairly sharp point is placed in the top of the screw and is held by a large cotter pin. The idea in bringing the top of the jack to a point is to give a firm hold. For ex- ample, if a frame is to be jacked up this point will enter the metal just enough so that there will not be any danger of slippage, and at the same time the point- ed construction insures that the load will always be applied at the center of the jack. Two jacks are required, one on each side of the frame, if an axle is to be removed.— P. T. Ryan, Ryan's Ga- rage, Troy, N. Y.

This board should be marked off as shown in the accompany- ing illustration, and under each name there should be a place for the special tools required in repairing each particu- lar make of carbureter.

The door IS not hung on hinges. Instead, it is suspended from trolleys running on over- head rails. There are two trolleys, one at each upper corner of the door, and they run on rails set at right angles, as shown in the illustration. To open the door, the handle at the end Y is grasped and pulled; to close it the handle at the opposite end is pulled. In either case a middle handle helps matters. The door opens flat against the wall. When closed, the trolley X runs to the position shown at A and the trolley Y goes to B. Mil- ler worked out this arrangement because he had to.

I« Making and Using a Motor Stethoscope (No. 34) A powerful stethoscope for locating motor knocks can be made at small ex- pense. It consists of a cylindrical cham- ber about 4 inches in diameter and 4 inches long, to one end of which is at- tached a long rod which touches the motor and from the other run two rub- ber tubes, one to each ear. The cylin- drical chamber may be made of any convenient material. The rod end of the chamber is made of shim steel .007 inches thick, and the end of the rod is at- tached to it by riveting. Near the other end of the chamber is a copper dia- phragm, number 16 gauge. The opera- tion of the device is simple. The tubes are placed in the ears and the point of the rod is rested on the place on the car from which the noise seems to be coming. The vibrations pass from the motor, up along the rod to the steel dia- phragm, whose vibrations set the air in the chamber in motion so that the cop- per diaphragm also vibrates and trans- fers the sound to the small chamber which communicates with the ear tubes. — L. E. Hughest foreman, Troy Auto- mobile Exchange, Troy, N. Y.

Then it is tested on the different gears at different car speeds as regis- tered by a speedometer suitably geared to the drum shaft. In each case the pull on the brake arm is noted, and if It is not as great as has been found on previous cars of this make and model, the reason is found.

Often the tool is thrown down on a lit- tered work bench and when it is needed again it takes many minutes to find it. The solution is to have a definite place for each tool and return the tool to this place. The most convenient place to carry the tools is in a wall cabinet back of the bench. This cabinet may be made of white pine, and may be almost any width and height and should be about 4 inches deep. It may be pro- vided with a door swinging upward and which may be padlocked. The tools rest on nails, and the location of each tool is indicated by a pencil outline of il on the back of the cabinet. This is made by placing the tool flat against the back of the box and running a pencil around the edge. The wall cabinet is much handier than a drawer in the bench for if the latter is used it is often necessary to move every tool in the drawer before the one wanted is found. It is easier, also, to hang the tool up than it is to open the drawer and throw the tool in and close it again. — Arthur Cashmore, foreman, Franklin Motor Car Co., Albany. N. Y.

Both devices are so simple that they need no explanation further than to say that 2x4 and 4x4 inch stock is used as indicated. The advantage of these stands is that they provide a safe means for supporting the car; there is no dan- ger of it toppling over.— H. W. York, foreman. Van Motor Co., Newburgh, N. Y. Handy Dissassembling Stand (No. 63) An excellent motor stand which wilt hold all of the various motor parts which may be removed and will hold the motor as well is illustrated herewith. This can be made of 2 x 4^8 and will provide a place for all of the small parts which ordinarily would clutter up the floor or the bench. The construction of this stand requires scarcely any explanation. The platforn: at the top is for the motor and beside it there is a well about 6 AUTOMOBILE REPAIRSHOP SHORT-CUTS supplied. A home-made device for this purpose is illustrated herewith. The two coils' in this case were taken from an old arc light and the switch was made from the parts of an old discarded switch used for another purpose. In use, the two contacts of the switch are placed in series on the battery charging line. Then when the switch is closed the cur- rent flowing through the coils will cause the switch to remain closed because of the pull of the magnets. Immediately the current fails, the switch will open by (fravity, thus protecting the battery. — Chas. H. Parker Garage, Middlctown, Conn. inches deep to hold many nf the smaller parts. Under this there is a shelf and below the shelf there is a tall bin and a number of partitioned spaces. Be- neath the motor there are a number of other shelves which can be used for small parts.

It is an excellent plan to use an old, worn-out clothes wringer to remove the surplus water from chamois. Much of the wear on chamois comes from being wrung out in the hands of the washer. Using an old wringer will eliminate wear. — Aston Motor Car Co., Bridgeport, Art Gum for Cleaning Cloth (No. 69) Spots in cloth upholstery of closed cars may be removed by rubbing with art gum, which may be purchased at most stationery stores.

Attic Storage for Bodies (No. 70) In the ordinary one-story garage with a peaked roof there usually is much space between the roof and the sup- porting beams which is not used. There IS illustrated herewith one method that AUTOMOBILE EEPAIRSHOP SHORT-CUTS IS bas been adopted by a wideawake garage- man for putting this waste space to use. During the summer montha he hoists the winter bodies up to this space and securely fastens them in place. Here they take up no room that would be otherwise used, are out of the way and secure from damage. In the winter months the summer bodies are stored in the same way. — F. Sbolz, Bridgeport, (Ho.

Receptacles for Small Parts (No. 72) Accessories undergoing repairs can best be handled and transported in small pans or boxes. Magnetos, for example, can be taktn care of in bread pans 8 x 15 inches, and costing 10 cents. The advantage of using a pan is that it keeps the magneto parts together when it is disassembled; there is no time wasted in looking for lost screws, and no money spent in replacing lost parts; everything is in the pan. When new parts are put in the old ones are left in the pan and charges for new parts made according to the old ones left over. For the same reasons pans may be used for carbu- reters, shock absorbers and even starl- ing-lighting units, although boxes would be just as desirable for the latter. — Jos. M. Maier, magneto repairshop, Newark, N.J. Nipping Fire in the Bud (No. 73) The danger of fire when burning the carbon out of the cylinders can be elim- inated by shooting some P^rene into the pan before the operation is started. — L. E. Hughes, foreman, Troy Auto Ex- change, Troy, N. Y. Card File for Keeping Time (No. 74) Accurate time keeping in a small re- pairshop can t>e accomplished by the use of a card file. Whenever a job is started the mechanic makes out a card and records the time. If he is called away Irom this work, even for a few to adjust a carbureter, for example, he jots down the lime of leaving and re- turning. The file is on the work bench and is accessible to all and the correct- ness of the records are checked period- ically by the proprietor so that there is little chance for error.— P. T. Ryan, Ryan's Garage, Troy, N. Y. Recharger for Weak Magnets (No. 75) A magnet recharger which will quickly energize an^ type of magnet and which operates with four 6-voIt storage bat- teries in series is shown herewith. The Lores are l>i inches in diameier-and 5 inches long and are made up of bundles of soft iron wire 3/16 inch in diameter. Each bundle is bound together with fine wire and the whole is soldered. Around each core is wound 500 feet of No. 16 gauge copper wire. In setting these two coils up be careful to have them properly connected. With the windings of both coils running in the same direction, the bottom wire of one coil should connect with the top of the other. The magnets may be charged by contact by using the instrument just as it is, but the cores are removable so that the magnet may be placed right in the coils. To charge the magnets the switch is closed three times for S seconds each, and the magnets are gently tapped during this period, A (No. 7i) This eully nude recbiriir wUl put new lUe Into miEatto mafseli (No. Tfl) Center hole ii uted tot * coocentriied fire and end holei with ii lor a loot fire Universar Tuyere for Forge (No. 76) A new type of blacksmith's universal tuyere is illustrated herewith. Its ad- vantage lies in the fact that it may be used for a small, concentrated fire or tor a large fire suitable for heating large pieces. It is little more than a long, rectan^lar iron casting, perhaps SO inches m length and 8 inches square. The ends are left open. There are three holes through which the air reaches the fire. the larger hole, which is rectangular, be- ing in the center, with two smaller cir- cular holes, one at either end. When only a small fire is required the two cir- cular holes are plugged with iron plugs and the fire is then concentrated in the center. For long pieces, the plugs are removed from the circular holes. When the tuyere is in use the holes at the end are plugged with hardwood plugs, the object in having them removable being to permit the easy removal of ashes which drop through the large rectangular hole in the center.— Young & Hart- wright. Stamford. Conn. Wrenches Made from Tubing (No. 77) Scraps of Steel tubing, such as drive shaft tubing, can be used to advantage in making socket wrenches. The tub- ing is cut into suitable lengths and one end is formed to the hexagonal shape of the nut by heating it to a red heat, slipping it over two castellated nuts, brought face to face, and hammering it to the desired form. Castellated nuts are used because their faces are smooth and flat from end to end. A handle is 6 laced on the opposite end — L. E. [ughes, foreman, Troy Auto Exchange, Troy, N. Y. Locating Fire Extinguishers (No. 78) To make readily distinguishable the location of fire extinguishers it is an ex- cellent plan to paint a bright red circle on the wall behind them. This serves also to indicate that an extinguisher is missing should a workman forget to re- turn it promptly to its place. — Blue Rib- bon Garage, Bridgeport, Conn. Truck for Wheel Removal (No. 79) ' One man can remove a truck wheel by means of an adjustable skid mounted on casters. The wheel is jacked a little over 2 inches from the floor and the skid is slid under. The distance between the two wedge blocks is then reduced until the weight of the wheel is carried on the sk\d instead of on the axle bear- ings. The skid may then be pulled out with the wheel. The wheel may be removed from the skid by pulling out the block on the left and rollinir the wheel off of that end. Before this can he done the weidht of the wheel must be transferred from the blocks to the skid frame by backing ofi the block on the right. Putting on the wheel is jost the reverse of the operation just de- scribed. The construction of the skid is clearly shown and all dimensions are This skid is an adaptation made by John Mussler, of the Eliis Motor Car Co., Newark, N, J., of a design brought out by the Picrce-Arrow Motor Car Co. and is a real labor-saving device that is not difficult to make in an ordinary shop. Grinding Tool for Ford Valves (No. 80) An excellent Ford valve grinding tool can be made with little trouble from a Ford carbureter adjusting rod. The fork in the latter must be narrowed slightly to fit the valves and then the rod is cur off short, Haticned and sharpened, and then driven into a lile handle.— T. L. Gracey, Argyle Garage.

The advantage of this tool is that it is easier to apply pressure and a greater purchase for turning can be obtained — T. L. Gracey, foreman, Ar- gyle Garage, Brooklyn, N. Y. Stuffing Box for Valve Stems (No. 82} Leaky intake valve guides in an over- head motor can be simply and easily remedied, providing there is sufficient stock for the work, by placing a small stuffing box in the cage. The method illustrated herewith was devised for use on Reo cars though it might be made to work on other cars. The valve cage is removed and the valve stem guide drilled larger to a depth of 1 inch, leaving a small shoulder at the bottom. The hole is then threaded. The removable por- tion which serves as the new guide is correspondingly threaded and a small cup-like depression is left at the bottom to act as the stufling box. For packing, a few strands of asbestos thread lubn- i:ated with graphite grease is used. The work can be done at a profit at $1 per cylinder, — C. J. Gowrie, manager, Reo Service Station, Hartford, Conn. Protecting Painted Fenders (No. 83) To prevent dust from settling on newly Tarnished fenders place them on a table •o that their surfaces are vertical and clamp them in this position. No matter how much care is taken there is usually some dirt in the drying room; it does not settle on the body because the sur- faces are vertical or nearly so, but it does collect on the fenders because they are generally laid flat.— W.

If there ia an electric drill in the shop this may be brought into service for certain classes of work by placing an emery wheel on the drill spindle and supporting the whole on the tool post of the lathe. This is accomplished by fitting a rect- angular bar the size of a lathe tool to the case of the drill motor and then this bar is slipped into the tool post. — M. K. Potter, foreman, Wm.

It is constructed of ordinary ^•inch boards and has two compart- ments, one for brass and aluminum and the other for iron and steel. The mate- rial is removed through a large door in the bottom which is ordinarily held closed by means of a large board latch, as shown. The particular advantage of the bin is that it keeps separate the iron chips and the brass and aluminum ones. These are sold separately as scrap. When sold together their value is much less. — W. W.

Cutting Slots in Valve Stems (No. 101) Valves for old cars often can be made screw at one end t the jig will slip oi In using the jig the first step is to adjust the stop screw so that the guide holes are at the proper point on the stem. Then the jig is clamped and the three holes drilled; the set screw is loos- ened and the jig moved back so thai two of the Jig holes are over the spaces between the holes just drilled in the stem. Two holes are drilled at this point, and then the jig is removed. The five holes thus drilled so close together produce a satisfactory slot for the valve spring key. — August W.

It may be charged by the apparatus used for charging mag- neto magnets, and the steel is so hard it retains its magnetism for a long period. — V. L. Warren, Ashtabula Ga- rage, Ashtabula, O.

The application of pressure would be somewhat more direct and the pres- sure applied to the long end of the lever would be more economically transmitted if (he valve end was forked so as to pass on both sides of the valve stem. There would be less tendency to tilt the valve. The valve end of the tool should, in any case, be smoothly rounded so that it could slide on the valve as the latter moved up when pressure was applied. — T. L.

Jacking in a Demountable Rim (No. 156) A split demountable rim, the ends of which refuse to snap back into place easily when the tire has been put on, can he forced by the use of an ordinary jack. The jack is placed inside the rim, and several blocks of wood are placed under the jack, as it is too short to span the diameter. Pressure is then applied and the ends snap into place. Care should be taken to make sure that the rim is free to go into place — that is, that there is no obstruction to its movement other than normal spring and fHction. Should its movement be blocked the powerful thrust of the jack might easily cause a permanent set. — Cylde Ward, foreman, Frank P, Beck. Marion, O.

An old electric generator of suitable ca- pacity and voltage is the principal neces- sity, and it can be purchased at small cost second-hand. No particular skill is required to make the installation. For example, the City Garage, Con- neaut, C, makes its own electric light under the method outlined and saves about $20 per month thereby. Formerly the cost of current at 8 cents per kilo- watt was $25 per month, while now the same light is furnished by $5 worth of natural gas at 30 cents per 1,000 cubic feet. Although a hit-and-miss governor engine is used, little trouble is exper- ienced with flickering; a throttle gov- erned engine is preferable, however. In making such an installation there are really only two things to bear in mind, assuming, of course, that the wir- ing has already been put in for use with city service — one is the selection of a generator of proper capacity and volt- age and the other is the determination of the proper size of pulleys to use to transmit the power from engine to gen- The voltage of the generator should be approximately the same as that for which the system was laid out, usually 110. The kilowatt capacity of the gen- erator should be at least equal to that required by the sum of the lamp ca- pacities. The ordinary 16-cand1epower Mazda lamp takes about 20 watts and a carbon lamp of equal lighting power 50 to 60 watts. Therefore, if there are, 60 16-candlepower Mazda lamps, 60 times 20, or 1,200 watts capacity, would be required, or 1,2 killowatts. The kilo- watt rating is invariably marked on the generator name plate. The ratio of the pulleys on engine and generator should be inversely propor- tional to the speeds of the two machines. If the engine runs at 300 and the gen- erator at 1,500 r, p. , m., the latter runs five times as fast as the former and therefore it should have a pulley one- fifth the size of the one on the engine. — P. W. Cowie, City Garage, Conneaut. Small Parts in Rotary Case (No. 160) A rotating cabinet for holding small parts is an excellent time saver in the shop, for it allows a nut or a bolt to be obtained in a minimum time.

Then a piece is made to go in the hole so that when it is inserted the puller is its original size. By this simple scheme the two halves of the puller are first slipped through the hole in the race and then the center piece expands them so that the right shoulder catches on the edge of the race. In order to pull the bearing off, a cap, as shown, is placed over the large end of the puller itself and fast- ened in place by means of the two screws which fit into holes in the shoulder of the two halves. Then by screwing up on the screw in the center of the c»p the bearing is pulled off. — ^John Van Ben- schoten. Van's Garage, Poughkeepsie, N.

Brake Drums for Testing (No. 162) Lining up and adjusting brakes may be facilitated by having a set of test drums, one for each car model; this is, of course, only feasible where a great number of one make are repaired. An ordinary brake drum with a section cut out of it so that the action of the internal brakes may be observed is all that there is to the test drum except for the han- dles, which are merely a convenience in Special Bearing Pullers (No. 165) Where a great many cars of one model are repaired in the course of a year, a bearing puller for inaccessible bearings will be found to be of advantage. One type for ball bearings is shown in Fig. 1 and another for roller bearings, and some ball bearings, is shown in Fig. 2. The former consists of a plate with several holes drilled near its circumfer- ence. Through each one of these holes is placed a metal strap with a small nut and washer on the end. The thinness of the straps allows them to pass between the balls and when the washers are bolted in place the bearing may be drawn out by turning down on the big screw in the center. With this device it often is possible to take out a defective bear- ing without dismantling the motor, gear- set or axle, as the case may be. The puller shown in Fip. 2 can be used only when the shaft inside the bearing has been removed. The principal part of the i>u!ler is shown at the top of the drawing, and the diameter is but slightly smaller than the bore of the in- ner race. There is a deep shoulder at the left and a small one at the right.

The cylinder casting is attached to the shafting by two steel rods which are connected to the shafting through two large bearings. The cylin- der is prevented from rotating by a brace which runs diagonally to the ceil- ing. Small poppet valves are used, and both are automatic. The piston clear- ance is negligible and pressure is regu< lated by a simple automatic device which holds the intake valve open when a pres- sure of 120 pounds is reached. — Orville Hauser, ChiUicothe, O. [By increasing the clearance, the auto- matic pressure regulator is unnecessary; that is, with a certain space between piston and cylinder head it would be im- possible to raise the pressure beyond 120 pounds because at this pressure the amount of air in the clearance space at the top of the piston stroke would be just snflicient so tbat on the suction bulbs is that there is not the same danger of breakage through frequent handling, the bulbs are mote accessible and the stock on hand can be seen at a glance.— Wm.

Probably the average garage is called upon to supply 100 cars per month with distilled water for the starting and light- ing battery, and figuring that each takes a pint, the total monthly consumption is over a dozen gallons, and the cost of $2.40. Herewith is illustrated a simple form of still consisting of three vessels, one for ordinary water, one for condensing Steam, and one for holding the distilled water. Water is poured into the first vessel through the filler opening and then the opening is closed. A gas burner under this vessel soon brings the water to the boiling point and the steam gen- erated is carried over through the coils of pipe where condensation occurs. From here the water flows by gravity into the vessel in which the distilled water is collected. The condenser coil should be surrounded by comparatively cool water to aid in the condensation. Six or eight feet of tubing ^ inch in diameter should be suflictent for the coil. If the distilled water vessel is solidly connected to the lower end of the con- denser tubing a vent should be placed in the side of the vessel near the top to allow air to flow in as the water is drawn oft through the faucet at the bot- tom. A gauge glass will be found a con- the of water in the vessel. A glass bottle may be substituted for this vessel. The material used in making the still should be thin sheet copper, or tinned or galvanized sheet iron. For 1-, 2- or 3- gallon sizes make all three vessels 5 x 10, 6J4 X 13 or 8 X 16 inches. Bucket Improvement (No. 239) The life of buckets and cans about the parage can be greatly prolonged by lin- ing the bottom with a H inch of con- crete.

Finally place the third spring in position at the back of the piston and then the ring may be pulled off. — John J. Stcpicke, Chicago, III. 1 Aligning Main Bearings (No. 247) Whether the main bearings are in alignment or not can be determined by means of a surface gauge. This is an instrument which measures the distance between the top of the crankcase and each bearing, and is therefore nothing more than a caliper. It has a broad, flat base, which may be placed on the surface of the crankcase and the pointer i) brought into contact with one of the bearings, then it is moved along to the other bearings to determine whether these surfaces are higher or lower. To make sure of the accuracy of this method the trueness of the crankcase surface must first be checked by a straight edge. Another method which may be used, providing the bearing boxes are in line, is to remove the bearings and caliper them. If they are all the same thick- ness the crankshaft must be in align- ment, but if otherwise it is out of true. — G, B. Cortelyou, New York. Elevator Safety Lock (No. 248) To prevent the use of the elevator by unauthorized persons the device shown was worked out. It consists of a hook which normally rests in one of the slots in the pulley around which the elevator starting cable is wound. The cable can- not be moved and consequently the ele- vator cannot be started until the hook is moved out of one of the slots, and there is a slot for each floor. The hook is held in position by a spring and it is pulled out by two strong electro mag- nets which are energized by an ordinary storage battery; there is no reason why line current might not be used just as well, providing it is direct. There is a switch at each floor, and when any one of these is closed current energizes the magnets and pulls the hook away from the pulley. Ordinary switches are used but special keys arc fitted ao that only a man with a key can operate the switch. — Floyd Kinnamar^and Wm. K. Knowlea, Fostoria, O.

Shaft Straightening (No. 306) Trailer for Hacking (No. 309) Many odd dollars can be picked up by using a trailer in connection with a hack- ing car. For example, trunks and freight may be brought from the station in it, and when a family is moved from a near- by summer resort back to town or vice versa, they may be moved bag and bag- gage, literally. There are a thousand and one uses for it, since it take the place of a small truck or delivery car. The shaft should be heated to a red heat at the place it is bent and then should be placed in the lathe. The bend may be removed by applying pressure with a jack, as shown, and at the same time the other end of the shaft should be struck several times with a hammer. The blows of the hammer cause the shaft to vibrate so that it gives way under the pressure of the jack and is thus slowly brought back to its original shape. — W. Wood, Packard Motor Car Co., Newark, N.J. Cylinder Lap. (No. 307) This cylinder tapper consists of an ad- justable cylindrical member, about the size of the piston, faced with sheet lead.

If the connecting rod is found to be bent it may be straightened in a vise or by the tool illustrated. When the connecting rod is straight, the true- ness of the piston is tested, for it may be that the wristpin hole ii crooked. Piston and connecting rod are placed in the jig together and then the edges C are brought into play. These edges are parallel to the connecting rod and show How anglss may bs Mnt In arbor proas axle or steering gear. Such a device is particularly applicable to one make of car, such as the Ford.— L.

The end piece, which is per- manently attached to the brace or not as desired, is drilled through the center and notched at the end so that it fits right over the wing nut. — M. Gerard, Park, lit. AUTOMOBILE REPAIRSHOP SHORT-CUTS Lining Up Wheels (No. 359) When tires wear rapidly or the car Bteera badly it is well to determine whether the front and rear wheels are the same distance apart on both sides. There arc many ways this point may be determined, but probably the quickest is to make a gauge out of a rod and a piece of tubing', adjustment being obtained by sliding the one in the other. The two are locked by a act screw. — F. W. Gear, Forty-ninth Street Garage, New York. Drilling Curved Surfaces (No. 360) An old man which may be used for drilling on curved as well as flat surfaces is shown herewith. It allows the ratchet to be placed perpendicular to the plate A on the old man. This plate may be adjusted to almost any angle by mov- ing It one way or the other in the toothed rack. The latter may be purchased by the foot and then riveted to the old man, which is made out of heavy flat steel stock.— W. A. Raban, Portchester, Lapping Crankshaft Bearings (No. 358) For lapping the crankshaft bearings it will be found convenient to clamp one end of the shaft to the bench, as shown, and allow the other to rest in a notched standard which may be nailed or bolted to the floor. A rest like this will do for any size crankshaft. — B. G. Smith, Rich- bell Garage, Mamaroneck, N. Y.

Under. ordinary conditions the life of a pair is only about a month, which means a charge of $5 or $(S each time. The life can be increased nearly ten-fotd by rein- forcing the boots by cementing old tire tubing over the boot so that its surface is completely covered. The soles and heels are shod with metal plates, which may be obtained at the shoemakers. — George E. Easier, West Ferry Garaae, Bu6Ealo, N. Y.

The band is made in two parts which are ad- justable at the back by a series of holes in one member which catch in a rivet head on the other. These holes give a rough adjustment while the band is drawn tightly around the rings by the wing nut at the front, which is hinged to one of the members and engages the other through a forked construction. Another Rod Test (No. 363) A simple -method of determining whether the connecting rods are true and their bearings parallel, providing the crankcase is not integral with the cylin- ders, is shown here. A long mandrel is placed through the piston, taking the place of the piston pin. Then either side is tested with a surface gauge and if both sides are the same height the rod is all right. Before this teat is made, however, the upper surface of the crankcase must be tested for straight- ness by using a straight edge as shown in the illustration. When using the surface gauge the pia- ton must not fall to one side or the otner the slightest amount, and to prevent this a try square should be placed at each a bench holds a This adjustable tool ■ 04 AUTOMOBILE KEPAIRSHOP SHORT-CUTS side as shown.

Drilling Cylindrical Parts (No. 3«4) Where there are many cylindrical parw of one kind to be drilled, the jig shown may be used to advantage. This was designed for wriatpins. The wristpin is placed at the bottom of the V slot and then it is clamped firmly in place by the two large set screws. There is a stop at one end of the slot to prevent the wrist- pin from moving more than so far and the cross -members may be moved near together or farther apart to accommo- date different lengths of work.— P.
