STRUCTURES Application filed. June 25, 1910. Serial No. 568,830.

To all whom it may concern:

Be it known that we, WILLIAM E. Jones and CHARLES Cnno'rn sns, citizens of the United States, residing'in Hennepin county in the State of Minnesota, have invented new and useful Improvements in Drawers for Filing-Cases and Similar Structures, of which the following is a specification.

()ur invention relates to improvements in drawers tures and particularly to a drawer of the class having an extension support adapting it to be opened its entire length without detaching; it from the cabinet.

This drawer is especially, though not exclusively, adapted for use in connection with steel filing cases, and is preferably made of steel. 7

The object of our invention is to produce a drawer of the class described which may he moved freely, easily and without jar, and which will be secure in the trackandcomparatively noiseless. ln devices of this class heretofore in use, have not moved synchronously, that is to say,

the drawer has traveled a certain distance,-

after which it has pulled or pushed the pan or support forward and back. By the peculiar arrangement of roller bearings which we have devised, the drawer and pan move together, the former r lding upon the periphery of the rollers and traveling double the distance of the pan on which the same rollers are axially journaled.

In the drawings, Figure 1 is a side elevation of our improved drawer and pan in a cabinet, the wall of which is partly broken away. the drawer being shown extended. elevation of the pangs portion of the drawer being shown in dotted lines. Fig. 3 is a plan of the pan. Fig. 4-, is a front end view of the pan. Fig. 5 is a detail showing one of the'rollers attached to the drawer, and Fig. 6 is a detail.

showing" an enlarged section of the track.

The tracks 1 are attached at the lower corners of the pigeonhole 2 (in which the drawer is placed) to the supporting bars 20 by rivets or any other suitable means. This track is formed with a lower flange 3, the roller way 4, and the upper retaining J 5. the purpose of which will he hereinafter more fully described. The extension support or pan (3 is formed with vertical sides 7 and top rails which are adapted to pass between the roller 4 and the retaining for filing cases and similar strnc-' the drawer and support flange flange Openings 9 are cut in the base 10 of the pan, a portion of the metal at the edge of each opening being turned up to form the ears 1.1. These ears have perforations 12 adapted to receive one end of the respective journals 13, upon which the rollers 1.4 revolve, the other end being" supported in perforations 15in the upturned edge of the pan. These rollers M travel on the roller way 4: of the track. To aid in securing noiseless action of the drawer. we prefer to make the rollers of wood fiber.

wars 16 are formed end of the pan and beneath these a portion of the pan is cut away to receive the wheels 17, the axle 18 of which is supported and journaled in the ears 16. Those wheels also run upon the roller way t of the track at contact abovewith-the retaining flange the purpose of this arrangement. being to hold the pan securely in the track and in horizontal aline ent when the pan is extended. wedge shaped, the broader portion being to ward the front to facilitate the smooth action of the-drawer as it is returned toward the closed position. Near the center and be low the pan, a stop 19 lS-HlJtiLChQd, whose function it is to prevent the sliding of the pan from the tracks by reason of the fact that said SiZOP'Wl'iGH the pan is extended comes in contact with the supporting bar 20 uponwhich t e lower flange 3 of the track is attached. i

The receptacle or drawer upon the rollers 14 of the pan, and as itis extended, fiw movement is facilitated with out sagging by rollers 22 which are. jour naled in the rear end of the drawer and so placed thatthey run under and are held in place by the top rails 8 of the pan. The

drawer 21 is prevented from running out ofthe 'end of the pan by stops 23 arranged on each of-the nptnrned edges of the pan, with on each side of the rear The sides of the pan 6 are slightly which the rollers 22 come-in contact when the drawer is extended to its outside limit.

It will be observed that the pen is mounted upon the rollers 14' and that the drawer travels upon the periphery of those rollers so that the movement of the drawer is just double that of the pan. When therefore the drawer is pulled out, it revolves the rollare 1% upon which it rests and the pan being mounted upon these rollers, moves with it until the limit of extension is reached by the action of the stops l9 and 23 on the pan tical side tion and the best mode in which we have contemplated applying that principle as well as in the f ollow ng claims, we have called the extension support for our drawer a pan but it is obvious that our invention is not limited to any particular form of extension support and by the word pan in the claims we mean any extension support for the drawer adapted to oo-act with theother elements named in the claims respectively.

Having described our invention, what we claim and desire to protect by Letters Patent is:

In a device of the class described, the combination of adrawer, 'tracks, retaining ed between said lips bearing upon the tracks and sup orting the drawer upon their peripheries, w eels mounted on the sides at the rear of the pan and engaging said tracks, and flanges for retainingsaid pan in hori-' zontal alinement, under-running rollers at the rear of the drawer engaging said rear- 'wardly inclined rails and retaining the drawer in horizontal alinement and stops to limitthe movement of the drawer-and pan, said drawer and pan being ada ted to move synchronously throughout their ntiremovement, the drawer traveling at twice the speed of the'pan. A

In testimony'whereof, we have signed our names to this specification in the presence of two subscribing witnesses.
