Fig. 35. Board on which
Tool Checks are Kept
First, the tools are numbered, as described above, and a brass check provided for each tool. Then a board, divided into squares, as shown in Fig. 35, is prepared. In these squares the names or numbers of the men obliged to draw tools are written. Each square contains two hooks on one of which twelve checks bearing the man's number are hung. When workman No. 2 receives tool No. 15, one of the No. 2 checks is taken from the board and hung above section No. 15 in the tool rack; at the same time one of the No. 15 tool checks is hung on the second hook in the No. 2 square on the board.
It will be readily seen that there must be, at all times, twelve checks in each square on the board, counting both tool and workman's checks. Reference to the tool rack will show how many tools have been issued and what workman has them. The advantage of this system is that it is practically automatic. A perfect record of the movement of tools is kept without the necessity of making entries on cards or in books.
Another method of operating the double check system is to supply the workman with a number of tool checks, these checks bearing the workman's number. When he wishes to withdraw a tool he presents one of these checks, which is hung above the tool rack. One of the checks bearing the tool number is then placed on the hook under the workman's number on the board.
One disadvantage of this system is that the workman is more liable to lose checks than he is to lose tools. Theoretically, the number of checks in possession of the workman at any time, added to the number of checks on his hook on the board, should equal the number originally given to him. If, however, he loses a check, it usually means a dispute, as the workmen naturally does not feel that he should be penalized by failure to return a check on which no tool has been issued. All things considered, the method first described is probably the most satisfactory.

32. Tool Records. While the system described above furnishes a complete check on the tools, it should be supplemented by a record which will serve as a perpetual record of values. The tools may be divided into two classes, namely, machine tools, and small tools, each requiring a somewhat different form of record.
Fig. 36 is the form of record for machine tools, this being on either a card or loose leaf. One card is used for each tool required. The record shows the name of the tool, the number, size, purpose for which used, and date made. Below this is a complete record of the cost, showing quantity manufactured, cost of material, labor, and burden. When tools are destroyed a record is made showing date and value, and the balance on hand is debited in the last column.
