DRAWER Gouin Application led November 15, 1927. Serial No. 233,482.

tained to prevent transverse movement of theA drawer between the guides, and as a result obtain an 'even and smooth sliding movement of the drawer in its movement in or out of the cabinet or desk.

The invention includes numerous other features which are more particularly pointed out in the following detailed description and claims directed to the preferred forms of construction, it being understood however,

that various changes in the size, shape and relation of the parts may be made which are within the scope of the invention as set forth herein. /f

In the drawings forming part of this application:

Fig. 1 is a transverse sectional view through a metallic desk or cabinet construction show-` ing a drawer mounted for sliding movement therein by means of the drawer guide construction of this invention.

Fig. 2 is a perspective of the case slide.

Fig. 3 is a perspective of the drawer slide. Fig. 4 isa horizontal section taken substantially on line 4.--4 of Fig. 1 showing the manner in which the case slide is mounted 1n a cabinet, desk, or the like.

Fig. 5 is a detail elevation of one end of a case slide showing a roller for supporting the front end of the drawer slide.

Fig. 6 is a detail section taken on line 6 6 of Fig. 5. i

A cabinet or desk construction includes suitable supports 1 which may be of any desired form of construction as used in the art, and a drawer 2 of any suitable form. The construction illustrated in the drawing is particularly adapted for use with metal furniture constructions.

A pair of case slides 3 are mounted on the supports 1 in spaced, parallel and opposed relation as illustrated in Fig. 1, each case slide being of similar construction. Each case slide is formed preferably of sheet metal to provide a channel member formed by the central portion 4 of the strip and the laterally extending flanges 5. The central portion 4 adjacent the op osite ends, is formed with outwardly struck) tongues 6 which extend in opposite directions, and are adapted to engage' in openings 7 in the supports l so as to provide an interlocking connection with the supports, to rigidly mount the case slides in position. In this mounted position of the case slides in the supports, the central portion 4 of the channel member extends in vertical relation while the flanges 5 extend in horizontal relation toward the opposite case slide. The flange 5 at the lower edge of the portion 4 has a laterally extending flange 8 formed vat the edge thereof which extends upwardly in the normal position of the slides as shown in Fig. 1 and partly encloses a portion of the channel provided by the formation of the slides.

Drawer slides 9 are provided on opposite sides of the drawer as shown in Fig. 1, which are preferably formed of metal strips having central portions 10 secured to the sides of the drawer. The opposite edge portions of the strip are formed to provide beads extending laterally on one side ofthe strip. These beads are provided by forming the edge portions of the strip with loilset portions 11 having laterally extending flanges 12 at the edge portions of these offsets which extend toward the plane of the central portion 10. The laterally extending flange 12 of the lower bead is provided With a lip 13 extending laterally therefrom and which, in the normal position of the parts, extends upwardly in a plane between the plane ofthe central portion l0 and the offset 11 so that the lip 13 is in spaced parallel relation to the sides ot the drawer. The drawer slide is constructed so that the distance between the flanges 12 forming the opposite edges thereof is slightly less than the inside dimension between flanges 5 ot the channel member forming the` case slide, which relation is clearly illustrated in Fig. 1.

The drawer slide has the end portion which is positioned at the rear end of the drawer, slightly rounded by forming the flanges 12 with curved portions as indicated-at 18", the curved portions in each flange extending toward the central portion 10. This provides for ready insertion of a drawer with these drawer slides into a desk or a cabinet so that the drawer slides will be easily received in the case slides. .The curved end 13 of lip 13 provides for the insertion of the drawer slides in the case slides and cams the beads outwardly under tension relative to the central portion of the drawer slide so that during the engagement of the beads with the flanges 8 in the sliding movement of the drawer into or out of the desk, the beads will be retained in engagement with flanges 8 under a resilient tension.

The drawer slides when secured to the drawer as shown in Fig. 1, interfit with the case slides so that the drawer is supported by the flanges 12, at the bottom edge of the drawer slides, in the case-slides on the bottom flanges 5 of the channel portions thereof. The drawer slides are substantially entirely received in the channel portions of the case slides as shown in Fig. 1, and the lips 13 are formed so as to have bearing engagement with the flanges 8. The flanges 12 provide for a relatively wide and long bearing contact between the slides in the support of a drawer `which aids in making the drawer easy to operate. These parts are so constructed that when the drawer is applied in a cabinet or desk. the lower beads on the drawer guides will have a lateral tension applied thereto through the special relation of the parts and through the resiliencv of the material of the drawer guides as well as the case slides. That is. the beads on the drawer guides will normally be spaced slightly closer together than the distance between the flanges 8 on the case slides so that when the drawer slides are engaged in the case slides the beads will be 'pulled apart and placed under tension to an extent which will be permitted by the flexibility of the material of the slides. This will insure a continuous bearing contact between the drawer slides and the case slides along the flanges 8 as well as the lower flanges 5 throughout the length of the slides so that the drawer will be effectively positioned and centered in a cabinet or desk for longitudinal sliding movement only. In the movement of the drawer in and out of a desk or cabinet, with this construction it will be held against lateral movement so that it can not become wedged in anv intermediate position. 'In applying the drawer slides to a drawer, the slides are made of a length so that the rear ends will extend a substantial distance lieyond the rear end of the drawer so that in the fully extended position of a drawer from a desk or cabinet, it will still be held against lateral movement and will be effectivelguided by the cooperation of this improve rawer guide construction.

Where this construction is applied to support substantially large drawers carrying heavy files, it may be desirable to construct the case slides as shown in Figs. 5 and 6. The forward end portion of a case slide is indicated at 14 in these two figures, having the upper and lower flanges 15 forming the channel member, while the lower flange is formed at its edge with the lateral and upwardly extending flange 16 similar to flange 8. The lower flange and flange 16 terminate short of and above the end portion of the case slide, and the forward end portion is provided with the extension 17 projecting down wardly, on which is mounted a rivet member 18 rotatably carrying' the roller 19. The periphery of this roller 19 projects slightly above the upper face of the lower flange 15 as shown in Figs. 5 and 6 and in alignment therewith in order to provide a bearing on which a drawer slide will engage so as to reduce the friction between the slides in the movement ofthe drawer in and out of the cabinet or desk equipped with this construction. In this wav, large drawers may be operated more easily than with the construction shown in Fig. 1 without interferring with the effective guiding of the drawer between the slides in centered relation. It is found. however, for the average size drawer used in filing equipment that theroller may be eliminated because the efficient guiding cooperation obtained bv this drawer guide construction permits of the easy operation of the drawer as shown in the. construction in Fig. 1 so that the roller will only be used in exceptional cases. 'lhe construction of the case slide shown in Fig. 5 is otherwise identical with the case slide shown in Fig. 1 and the same drawer slide constructions as shown in Fig. 1 are used with this case slide when provided with the roller. v
