tageously followed where only five or six are employed, to the ex tent of properly apportioning the responsibility and authority.

The plan shown at Fig. 3, A, is a one-story structure with a two-story frontage, having a capacity for 30 cars. The building is about 120 feet long and 40 feet wide, divided into departments for convenience. The ground floor contains four departments. The front apartment is about 40 by 20 feet, which is again divided, the tool room and office being 10 feet wide by 16 feet long, the machine room about 30 feet wide and 20 feet long. The rear of the shop is partly divided by a partition extending about 15 feet from the right wall, and about 20 feet from the rear wall. The right back corner is partitioned by a brick wall into a room about 15 feet wide by 10 feet deep, this serving as the boiler room for the heating plant. The space between the front and back portions, about 80 feet, is used for general repairing, for taking cars apart and storing cars ready for delivery.

The ground floor has been divided into four parts—the tool room and office, the machine shop, the assembling bay and the overhauling room. The second story is about 25 feet deep and as shown at Fig. 3, B, is divided into three parts, a stock room with 15 feet frontage, a battery room 10 feet wide and a tire repair room the same size as the stock room. The entrance for cars is at the side of the building, and the door opens into the large room so the machines can be run directly back into the overhauling department, or ranged along the walls of the assembling room. A short passage leads from the small door at the side directly to the machine shop, though all entering must first pass the office before gaining admittance to the other departments. The plan shown can be applied only where the building is located at a corner, or where there is a short street or alley at either side. This form of construction permits one to take advantage of the whole front of the shop, and no space is sacrificed, as would be the result if the main entrance and passage were located at the front of the building.

An office and tool room are partitioned from the machine shop by sheathing and wire netting or grillwork, the wood of the partition being about four feet in height, all space above to the ceiling being filled by wide mesh net. Thus the tool room is effectually

separated from the machine room, and yet all that goes on in either room can be seen by the superintendent when in one room or the other. Two partially open partitions extend the width of the tool room, the one separating it from the passageway, the other from the machine shop. In each partition is placed two windows, closed by swinging screens. Along a portion of the side wall and under the stairs are tool racks, while many of the smaller and often-called-for tools, such as drills, taps, dies, reamers, etc., are carried on pyramidical revolving racks. These racks can also be used to advantage for nuts, bolts, machine screws, splitpins and other small stock often demanded.

The bookkeeper and clerk share a common desk ranged along the side wall, while the stenographer has a typewriter desk between the two windows communicating with the passageway from the street. This makes it possible for the stenographer to wait upon customers applying at either window. The one nearest the door permits a visitor to talk with either the clerk or bookkeeper, while that at the other side of the desk allows the caller to talk to the superintendent or manager, whose desk is conveniently placed so that he can look into the shop, keep his eye on the tools and stock, talk with either bookkeeper or clerk, or dictate a letter to the stenographer without leaving his chair. As no modern business is complete without telephone service, a single desk instrument with extension cord is placed on the stenographer's desk, and can be used by the superintendent, the bookkeeper or the clerk without leaving their work.

How Raw and Finished Stock Is Stored.—The arrangement and type of the racks can only be determined by, the nature of the raw and finished material carried in stock. The stock room is directly ver the office and tool room and a dumb waiter or small elevator as well as a stairway connects both floors. At Fig. 7, A, is shown a type of rack that can be used to advantage in storing small parts, this having lower bins of larger size for bulkier articles. At B is shown a combination rack for stock, both finished and rough, having a series of pigeonholes for tubing, bar steel and iron, etc., while the type at C permits one to store sheet stock as well as other and less bulky articles. A practical form of rack

for bar iron and steel, tubing, etc., is at D, this being a series of cast iron members joined by through bars, so coupled as to act as braces. A most practical form of rack for the repair shop stockroom would combine the forms shown at A, B and C, the bars and rods being put in from one end, the sheet metal, fibre, etc., being placed in the compartments at the other.

There is no need of mentioning the ways in which nuts, bolts, machine and wood screws can be best handled. Any stock man of experience would place these in revolving pyramidical racks, or

small cabinets where they can be easily reached, which permits of marking for ready identification. Wire, rubber hose, flexible copper and brass tubing, etc., need only be coiled and placed on convenient hooks; pipe fittings, gaskets, and small parts should be strung on wires and suspended from nails; sheet packings, rubber matting, etc., ought to be left on the roll, and mounted on stands so they can be easily unrolled.

A desk should be provided for the stock man convenient to the stairs and dumb waiter or elevator. All smaller articles can be sent from one floor to the other by the elevator. The oil can be stored in the regulation pump-fitted tanks, while the grease can be kept in the original package if bought in bulk. These should

be stored in the tool room, as well as other stock that may be frequently called for. A good place for both oil and grease is under the stairs leading from the lower to the upper floor. A convenient storage place for waste is the interior of the revolving rack on which the smaller tools are placed.

• In all well regulated shops there is a system of tool checking, all of the workmen being provided with small brass discs punched with a number by which the employee is known, one of these being surrendered to the tool boy for every piece taken from the tool room, and which is returned to the workman if the shop tool is surrendered in good condition. All broken tools should be immediately reported to the master mechanic or superintendent. No deviation should be made from the established rule, and no tool should go out of the tool room unless properly checked.

Every stockroom should have two weighing machines, an ordinary spring balance registering to 20 or 30 pounds and a platform scale so that all raw stock bought or sold by weight can be weighed before acceptance or delivery, and it will be found a distinct convenience to have a certain portion of shelf, table or wall measured off in feet and inches by which the length of wire, packing, etc., can be quickly determined without frequent search for a mislaid foot rule or yard stick. A card index and good stock numbering system will facilitate finding the location and price of any raw or finished material, and this can be best worked out as the actual conditions demand, If the repair shop management operates a garage and agency in connection, spare parts for the machines should be kept entirely separate, and in different racks or bins, and distinct from the raw material.

Lockers and Washroom.-The arrangement of lockers, washing and toilet facilities are shown by the floor plan. The washstand may be a long cast iron sink, or the more sanitary enamelled individual steel washbowl series placed in the market recently. Twenty places are enough, but all should have separate hot and cold water faucets, though they can discharge into a common pipe. The location near the heater simplifies the plumbing and provides hot water without delay or waste. The lockers should be about 18 inches square and six feet in height, having a shelf about a foot
