For convenience of administration all these may be under the charge of the tool room foreman, while the special work of caring for, issuing, and receiving tools and the issuing of stock may be taken care of by a tool and stockkeeper and a young man, and perhaps a boy. There should always be two persons conversant with the location of every item of tools and stock in these rooms, so that the regular work may not be impeded in case of the illness or unavoidable absence of the man in charge.
The engraving, Fig. 190, presents a plan of these rooms, laid out in the most convenient manner, showing the location of the machine tools in the tool-making room and the various sections of shelving, racks, bins, counters, benches, etc., in the tool storeroom and the stock room, all designed and arranged with a view to efficiency and economy of operation, as well as the economical use of the floor space. This design is a variation of the one shown in Chapter XVIII (Equipment Of The Tool Room And The Tool Storeroom) and is designed as a secondary or alternate study to that one. It will be found useful to those about to organize the tool and stock rooms of a machine shop or factory in a practical and economical manner, and at the same time not sacrifice the important factor of efficiency.
Fig. 190. Plan of a Tool Department.
In addition to this general tool room there may be other distributing points, as the offices of the several foremen, or auxiliary tool rooms at remote points on the ground floor, or on other floors in case the shop is constructed with several floors. At these points, lathe and planer tools, twist drills, and similar tools may be had by the workmen without sending to the general tool room for them. If this is the case the regular routine of issue by the general tool room will be preserved as though the issues were made directly from it. To carry tools to these auxiliary tool rooms a device similar to the cash or bundle carriers in department stores should be used, while for carrying tools to and from other floors a conveyor consisting of two chains running over pulleys at the upper and lower floors, and provided with pivoted boxes, located between them, is very economical and efficient, and in successful use in some of the largest shops and factories.
The foreman of the tool room is supposed to have a small office, that he may have a proper place for keeping the records of the work of the department, as well as a private room for convenience in making such sketches, plain drawings, or details as he may find necessary in carrying out the plans for tool making, these not being always worked out in sufficient detail by the drafting room force, or such as he may wish to devise himself for special work, and to develop as the necessities for them may arise.
On general principles all drawings are supposed to be made in the drafting room, and by the regular draftsmen, yet there are times when the initiative in these matters may, with proper authority, be taken by the foremen of the tool room and the experimental room. In such cases the regular finished drawings of record should be made in the drafting room according to the regular rules of that department. In fact, it should be a rule habitually enforced in the whole establishment, that except for urgent reasons, or special orders from competent authority, the regular routine for transacting business should be insisted upon, and that "short cuts to avoid red tape" should be frowned upon and discountenanced.
When in the regular course of shop work, tools, jigs, fixtures, gages, etc., are required, the superintendent will issue a written order, of which he retains in his order book a carbon copy. These orders will be serially numbered, in duplicate (for general work in the shop in triplicate), and this individual order number will designate this particular work all the way through such departments as do any work upon it.
As the plan of organization I have advocated provides for two assistant superintendents, the first having under his jurisdiction the drafting room, pattern shop, tool room, experimental room, stock room, power house, iron foundry, forge shop, carpenter shop, paint shop, shipping room, and yard gang, while the second assistant superintendent has charge of the strictly manufacturing departments, an order for tools will go to the first assistant, who in turn will write in a carbon copy book a similar order for the foremen concerned in the work, furnishing a copy to the chief draftsman and to the foremen of the tool room, pattern shop, foundry, and forge shop, for the necessary drawings, patterns, castings, and forgings, respectively, and see that they are gotten out and furnished to the tool room foreman.
When the drawings are complete the chief draftsman will notify the first assistant, who, if he desires the job to go on at once, will direct him to send the proper drawings to the pattern shop and forge shop. In making these drawings, and in all subsequent work, the value of time and material will be charged on a material and a cost card of the form shown in Figs. 191 and 192.

Fig. 192. The Time Account (on the back of the Material and Cost Card).
The time account kept by the workmen is on a job time card which, in addition to the regular day time card, is registered in a recording time clock, a separate card being used for each job, and the aggregate amount of time so registered equaling the amount shown by the day time card. One of these cards is shown in Fig. 193, which is adaptable to the International card recorder time clock. At the end of the week these cards go to the office, the time clerk receiving the day time cards, and the cost clerk the job time cards.
