IMPROVEMENT IN PAPER-FILES.

Speciiication forming part of Letters Patent No. 119,917, dated October 17, 1871 antedated September 27, 1871.

To all whom it may concern:

Be it known that I, CASS CHAPMAN, of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Pigeon-Holes.

My invention has for its object to produce a frame or skeleton for the reception of boxes or drawers without the use of bolts, nails, or screws, which shall be perfectly portable and easy of transportation, and can be readily taken apart and put together again, Ste.; and consists in forming the same of thin sheet metal so cut and bent up that the parts are easilyinterlocked, and when so interlocked form a perfect, strong frame, as will be hereinafter more fully set forth.

To enable those skilled to make and use my invention I will proceed to describe the same reference being had to the accompanying drawing forming part of this specification, and in which- Figure l is a vertical longitudinal section at line a' a', 2. Fig. 2 is a vertical cross-section at line y y, Fig. 1, looking toward front, and Fig. 3 is side View, partial. Fig. 4 shows the parts detached.

Similar letters of reference indicate like parts in the several iigures.

A A represent the front and back of the frame; and B B, Ste., the division-plates or drawer-supports. These plates B are cut from sheet metal, of the proper length, and a little wider and longer than the bottom of the drawer. The excess in the width is turned up at right angles equally on both sides, as seen at 1, which forms side guides for the drawer after it has been inserted. The ends are turned down equally at right angles, the rear end passing through a slot cut for that purpose in the back of the frame Af; or they maybe passed through straight and turned down afterward, as seen at 2. The front end drops into its seat formed by the turn-up 3 at the mouth or opening in the front plate. This mouth or opening is made by cutting a hole corresponding to the shape and of less dimensions than the front of the drawer, and increased to proper size to allow the entrance thereof by turning inthe surface metal, as seen, except at the bottom, which is olea-n cut. The top is turned up, as seen at 3, forming the sea-t for the front turn-down end of the drawer-support, and the sides 4 turned in at right angles to correspond with the plane of the guides 1 formed by the turned-up sides of the plates B, thus forming a perfect guide on all sides for the sliding drawer C, which is made of about the design seen in the drawing, and provided with a suitable knob, D.

It will thus be seen that a cheap, neat, and substantial set of pigeon-holes is produced, which are proof against dust, vermin, and nre, and, be

ing perfectly portable and easy of transportation,

are very desirable.
