Other objects and advantages, of the present construction will be apparent from the following lwre detailed description, taken together with the a om y n hewin in which Fi u 1.1 a om. tlev isznalrien et PQW o a cabine and rawer stal t ur Wi h- .1 i entime a i hereto meat he vfirmw e a ts su p r ein hown sta n;

fFigureB. is a fragmentary perspective view of a unitary side rail and shoe shown in the other figures ofthe drawinga fragment, of. the drawer b t om sso a ed therewith bro en awa nd. in section.

R fe in ta l o th fi ur s of t aw n I have shown steel hra ckets 10, the horizontal portions of which provide runways II for the drawers [2. The brackets ll'l are appropriately fixed, in parallel relationwithin a. frame or cabin wh h m y be oce ed. or instance, b l aprinters eomp sine 109mcabi e The, drawers lz a re conveniently divides; into a pluralityof rectangular. compartments of varying sizes spaced as'h jongitndinal partitions l5 and transverse partitions M, for the reception and separation -Qf various type groups. Each draw reenerally has onesor more of the handles or pulls l6 of theunqer-finger-ty e Qr'GQm Qnience, and these are attached; as by screws I1 to the usual wood front strip it of the drawer which together with the wood side rails 19 and back st-riptll support the partitionsl4 and I5 and the drawer bottom boardvz I, the latter being securecl to the other parts asby nails :22. The wood side rail 49 conveniently recessed at its inner face to receive the end of the partition or slat with the lowercorner ofthe latter resting on the bottom board 2|, as clearly-shown: in the drawing (Fig. 1) without notchingof the partitionasat Ma.

The front strip [8 laps the ends of the side rails I9, the latter abutting and being secured thereto as by tenons 23 which are received and secured as by gluing them in appropriate sockets in the front strips. A similar mortise and tenon securement may be employed between the rear strip 20 and side rails IS, the side rails in this case lapping the ends of the rear strip and receiving the tenons 24 on the latter, as is well known in the art.

In accordance with the present invention, each of the wood side rails I9 has extending longitudinally along its outer edge an integral depending portion or rib 25 which, ashere shown, is desirably eccentric of a vertical center line of the side rail, and along its laterally facing outer side the side rail has a longitudinally extending groove 26.

The metallic shoe of the present invention for cooperation with this part of the side rail is in the form of a steel channel member 21, the channel of which substantially snugly receives the depending portion 25 of the side rail 19, desirably as by a telescopic end to end interengagement of the side rail and channel, from the rear end of the side rail.

In the present embodiment of the invention, the outer side of the channel member 21 is extended upwardly as at 28 beyond its inner side 29, and at the upper termination of the extension 28 the channel member is turned inwardly to provide a horizontal flange 30 snugly received in the side rail groove 26, the interengagement of the groove 26 and flange 30 serving in this instance to support the channel member and secure the rail depending portion in the channel. For further securement, the channel after being located in position as described, may be indented as at 3| into the wood of the side rail at its forward end, as by a suitable swaging tool or the like, to inhibit relative longitudinal movement of the channel member rearwardly of the rail, the drawer front strip 18 by abutment with both the front ends of the side rails and channels, as shown, serving to inhibit relative forward movement of these parts.

Along its outer lower corner the channel member 21 is desirably slightly offset laterally as at 32, in this instance, both from the side rail and from the upward extension 28 of the channel member, to form somewhat of a longitudinal bead.

So constructed and arranged, the drawer I2 is slidingly supported on the cabinet runways H through the intermediation of the channel mem bers 21 which in turn are reinforced by the depending portions 25 of the side rails so that, for example, when a drawer is pulled out of the cabinet part way, say, as shown for the upper drawer in Fig. 2 of the drawing, kinking of the channel membersis prevented at the points 33 upon which the drawer (of considerable weight if loaded with type) is then fulcrumed and which points 33 are the inevitably relatively sharp forward edges of the horizontal runways I I, upon which the drawer slides. The drawer at this time will rock somewhat on the runway ends 33 and will have its rear edge contacting as at 34 against the lower surfaces of the runways ll of the drawer next above it. The bead or offset 32 along the lower outer corner of the channel member 2! provides a sliding contact reduced in area for a minimum of friction between the drawer and the vertical portions of the brackets I constituting the runways for the drawer.

The eccentric depending portion 25 of the side rail l9 serves an additional purpose in that it provides an undercut 35 in which the margins of the drawer bottom board 2| are received so that the nails 22 may be driven vertically upward into the side rail while disposing the bottom board and its nail fasteners in a plane above the lowermost termination of the side rail depending portion, so that the drawer definitel rides on the channels 21 and side rail depending portions 25 and not on the bottom board. Moreover, since the bottom board thus advantageously snugly laterally abuts the inner wall 29 of the channel member, this arrangement further tends to secure the channel member in position, as shown.

It will be apparent that the channel member can be placed on the side rail in only the correct position and that the channel member may be conveniently aassembled initially with the individual separate side rail before these parts are put together with the other drawer parts, thus making the side rail and channel member a unitary structure in themselves, having mutually reinforcing interengagement, further facilitatin rapidity and economy of manufacture and efficiency of structure and operation.

Having described my invention, I claim:

1. In a drawer structure having metallic shoes for slidingly supporting the drawer upon drawer runways, the drawer having non-metallic side rails abutting at their forward ends a front strip of the drawer, the front strip lapping the ends of the side rail, the combination including an elongated eccentric depending portion on each of the side rails, a metallic channel member at each side of the drawer substantially snugly receiving said depending portion of the side rail, the outer side of said channel member being extended upwardly beyond its inner side and being at its upper termination turned inwardly to provide a horizontal flange within the vertical projection of the channel member, and a groove in the side rail receiving said flange to support the channel member, the channel member and side rail being interengaged by an end to end telescopic movement, the channel member being bulged slightly outwardly along its outer lower corner to have its outer wall laterall offset both from the side rail and from the adjacent upward extension of said channel member and being indented into the wood of the side rail at its forward end to inhibit relative longitudinal movement of the channel member rearwardly of the rail, the drawer front strip inhibiting relative forward movement,

2.
