A Manager's Desk File
A DESK file for managers, which obviates the unnecessary handling of salesmen's data, is shown in the sketch. It consists of a board for a base into which a number of slots are cut to re- ceive division boards in an upright position. The base in this instance is 1 8 ins. long, 8 ins. wide and Js in. thick, cut and finished from a piece of quarter- sawed oak to match the flat-top desk on which it is placed. The surface of the board is laid off in divisions of i in., allowing % in. for the grooves.
The >4-in. boards forming the division l)arlitions are rounded on both upper (orners, and they are cut as long as the ba.se is wide. A back board, cut as long as the base, is fastened to its rear edge to prevent pajjers from being pushed en- tirely through the file.
The division boards are cut to fit the grooves snugly, so that one may be re- moved, if desired, to make a wide space for any special purpose. Of course these can be glued in solidly. Domes are driven into the under side to pre\ent scratching the surface of the desk.
On the front edge of the baseboard are placed the names of the salesmen, and any matter recpiiring their attention is slipped into the proper place. This handy little device serves its purpose Well iu this instance.
