I Y Application led September 7, 1926. Serial No. 133,842.

This invention relates to improvements in drawer slides. Y

An object of the invention is to provide a drawer slide of novel construction which will enable a drawer to be completely withdrawn from within the structure supporting it and which will rigidly support the drawer in its withdrawn position.

Another object of the invention is to pro- 19 vide a drawer slide of lnovel and simple construction'which may be easily, `quickly and cheaply manufactured, andv which may be easily and quickly applied toa drawer. A further object of the invention is to prok vide a drawer slide having the above mentioned characteristics which occupies a very small amountof space between the sides of the drawer and the sides of the supporting structure. lVith the foregoing and otherf'objects in view which will bemade manifest in the followingr detailed description and' specifically pointed out in the appended claims, reference is had to the accompanying drawings 2 5 for an illustrative embodiment of the invention, wherein:

Figure 1 is a perspective view of the supporting construction and a drawer to which the improved slide has been'applied, the

drawer being shown in its fully open position.

Fig. 2 is a vertical/section taken through the supporting construction and drawer shown in Fig. Fig. 3 is a perspective view of the drawer slide, i

Fig. 4 is a view in side elevation of the supporting construction with the drawer therein7 parts being broken away to illustrate the drawer slide,

Fig. 5 is a perspective view illustrating a slightly modified form of construction,

Fig. 6 is a verticalV transverse section through the construction shown in Fig. 5, and

Fig. 7 is a perspective view of the modi tied drawerslide shown in Fig. 5.

Referring to the accompanying drawings` wherein similar reference characters designate similar parts throughout, the supporting construction may be of any desired form, such as in a table, cabinet, cupboard, or the like. In the'present instance it is illustrated as consisting of a pair of side walls 10 and 11 connected by a back wall-12 and the forward ends vof the side walls being connected by top and bottom pieces 13 and 14. Flanges 15 are provided at the bottoms of the slde and back walls 10, 11 and 12. The drawer employed may be of any desired construction and'is illustrated as consisting of afront wall 16, side walls 17 and18, a back wall 19 and a bottom 20. The ends of the front wall 16 project laterally a short distance beyond the sides 17 and 18.

Between the side 17 of the drawer and the side wall 1() there is disposed al drawer slide generally indicated at 21, and in' a similar manner another drawer slide which is a counter part of the slide 21 is disposed between the side 18 of the drawer and the side wall 11. This second drawer slide is indi` cated generally at 22. Each drawer slide is constructed as follows: Itvconsists of a section of sheet metal which has its top edge bent laterally to provide a top flange 23 ex tending from one side of the section. The bottom edge of the section isalso bent laterally to provide a bottom flange 24 projecing laterally from the other side of the section. One end of the top flange, however, is

not bent kto provide an upstanding fin r 25 and in a similar manner there is provi ed a downwardly extending linger 26 at the opposite end of the bottom flange 24. Grooves are formed in the tops of the side walls 10 and 11, such lgrooves being indicated at 27. These grooves are adapted to receive one of the flanges on the slide, such asfor example the top flange 23. In a similar manner grooves 28 are formed upon the outside surfaces of the sides 17 and 18 of the drawer to receive the bottom flanges 24 of the drawer slides. If desired, metallic channels 29 may be positioned in the grooves 27 andr28,with

-in which the flanges on the slides are slidable,

thus reducing wear and also the friction betweenthe slide and the sides and side walls.

Guides are provided which are indicated generally at 80, each guide consisting of a small rectangular section of sheet metal having one portion 31 bent out of the plane of the other portion 32 so as to be parallel to it. One of these guides is mounted upon each side of the drawer at about* its center in such a manner that the portion 31 overlies the bottom of the drawer slide. an .other of these guides is'mounted on each side wall 10 and 11 at about its center, and has its portion 31 overlying the top of the drawer slide. These guides which are fas'- Vtened by screws passing through the a ertures serve to maintain the flanges in t ieir respectivegrooves. 'They alsofserve an additional' function. They are engageable by the fingers and 26, thus forming stops which limit the movement of the slides; In

sie

. ported in the preferred form of ,construction lugs-34 are struck out of the portion 32 of each guide, yand .these Alugs `are arrangedatlthe center of .the Guides. so that all .ofthe guides are interchangeable and will not have to be constructed in pairs. The lugs 32 extend intonsmall `vertical grooves .or slots formed in .thecsides 17' and 18 and theside .walls lO and 1l resneetvelyc From 4the above ,described constructionii-t be l appreciated that pn `pulling the drawer open, the drawernsually will iirst Slide uren the drawer Slides .2l and 22 until .the l guides mounted on'the .sides ,of the' gaglg L side wall of the drawer in this position for substantially half itsleng-th and `also ,each side wall for substantially half its length, the drawer will be `firmly supthis ,completely withdrawn position. f

Inciosing'the drawer, usually the drawer -first :slides relatively `to the slides 21 and 22 .untilthe forward ends of the slides engage the lprojectinglateral ends `of .the front wall 164v of 'the drawer. Then the slides are Acaused lto slide backwardly with the drawer relatively to the side walls l0 and 1l.

,In the modification shown in Figs. `5, 6-

and 7 the construction of the drawer slide is follows: `The slide consists of a see,-v

t-ion of :sheet x'netal 3,5 having' its upper edge bent over to provide the top flange 36 and .this tQP flllgefhas's edge bent dow wardly as 37.1 4',Ihe bottom ledge `of the section 35 is bent outwardly vas. at 38 from vthe opposite side and then upwardly kas at Y Inthis .way there are formed two chan nelswhich are located on opposite sides of Vthesectionimflivets extend across the a `,channels and have a staggered arrangement.

Rollers, $1 are rotatable on the Vrivets and son@ @f1 the vtolli-as have portions ,extending 'through apertures farmed in the portions-.36

and respectively. The other rollers have portions projecting beyond the edges of thel flanges 37 vand 39. The drawerslideof this construction is mounted between the sides of the drawer and the side walls in a manner very siinilarito that previously described.

In the grooves there are provided channels `a2. I n the upper groove those rolle-rs 4l,

which have portions extending through the yapertures in the iange 36, roll against the tops of the. channels while those rollers which have portions below the vbottom edge of the flange 37 roll on the bottomsof ,the

channels, I n .rasimilar manner the rollers between .the section 35 andthe flange 39 roll against-the top and bottom of the channel in .the groove on the drawer.' In this -modiiicationiingers 43 are provided in the ends of the slide and also guide means, which are ,substantially the same as the construction shown in Figs. l to i. The 'modi fied form of ldrawer slide is designed to support large heavy drawers in large cabinets where :the weightsupported by the drawer is apt `to be considerable.v The modification shown in Figs. 1 to 4 inc. is

designed for-use where Itlieklrmver will probably hold articles of light weight.

From the yabove .described construction it will be appreciated that a novel drawer slide is provided, which may be very easily, quickly andcheaply. constructed; Furthermore, the improved wall slide permits the drawer `to ibe completely withdrawn from within lfthe supporting construction and to be. firmly supported -i-ts withdrawn position. Lastly, theimproved drawer slide occupiesbut .a very small amount of space between the sides of the drawer and the' sides of ,the supporting construction, so that it will be neat in appearance and will prevcnt lateral movement of the drawer which .mshtloosen vthe Slide- Y It will'be und rstood that various .changes may be made in the detailof construction without departing from the spirit 'and scope of the invention as dened by the appended claims. l Y i 1.
