6 Claims. (Cl. 217-63) and is easily movable to open position to render r posed below the operate therewith to effectively brace the side the contents accessible. Another object of the invention is the provision in-a cabinet of this class of a novel and efiicient means for assembling and guiding the separate it sliding cover members in the cabinet. a

i Fiu'ther objects'and advantages of the invention will be apparent from the following detailed description, and from the accompanying drawing, in'which- Figure 1 is a perspective view of a cabinet embodying the invention, with the cover members in closed position; Fig. 2 is an enlarged longitudinal vertical section taken on the line 2-2 in Fig. 1; Fig. 3 is an emarged fragmentary section taken on the line 33 in Fig. 2; Fig. 4 is an enlarged fragmentary section on the line 4-4 in Fig. 1, and Fig. 5 is'an enlarged perspective sectional detail of the bottom .end' portion ofa cover melmber, together with a portion of-an engaged Referring to the drawing, l, two opposed side walls of the case which are rigidly connected at their ends, preferably near their top edges, by respective cross-bars 2, and intermediate said bars in spaced relation thereto by a bottom member 3. The member 3 is displane of the bars 2, so as to col designate the positely sliding cover members 5, 5, the side edges of which are mounted for sliding movements, in the manner of roll-type covers, in respective grooves 6 provided in the inner sides of the side walls I, l. Both covers, for simplicity of assemlin 6 which extends over the bottom 3 lengthwise of the respective side'l near its top edge, and at the end of such member extends downwardly and inwardly in curved form around the ends of the invention is the provision of a and enclosed at its are mounted at each edge in a single groove bottom, at the inner sides 0 f the bars 2, with its ends extending in parallel lapped relation under the bottom and past the can The lower one of the lapped and opens without the bott ter line of its length. ends curves down to om edge of the side member, as shown at 1 in Fig. 2.

In assembling, both covers 5 are threaded into the guide grooves through the open ends I thereof and are then moved around to the position shown in Figs. 1 and 2. A screw 8 may then be inserted in each groove near as a'stop for limiting the op adjacent cover.

its open end to serve en movements of the A stop 9 may also be inserted in the central top portion of each groove to limit the closing movements, of the covers.

Each cover 5 comprises a single sheet of fairly stiff resilient material, which is preferably, but not necessarily, transparent to permit the contents of the case to be viewed therethrough. This material has the appearanc e of celluloid, and is preferably of a.noninflammable cellulosic nature.

Each sheet'5 at its top end is attached to a cross-bar I0 which is lengthwise slotted to receivethe sheet edge. Pins edge in the bar. ,Each end H anchor the sheet of the bar III has a guide pin lZprojecting centrally therefrom and engaging within the respective groove 6 (Fig. 3). The opposite end of each cover 5 is stiffened by a crossbar I 4 preferably of angle form. One flange of the bar has its ends extended to enter the grooves 6 for movements therein. The bar, in its present embodiment, is composed of sheet metal bent in angle form with the metal at the outer edges of the flanges extended and bent back upon the outer side of the render it of double thickness respective flange to The adjacent edge of the cover sheet is attached to the bar by being clamped between one of said flanges and its turned-back portion, as shown in Fig. 5. It is found' in practice that the ease of movement of the edges of the grooves 6 is facilitated by cover sheets in the crimping the sheet edges at spaced intervals, as shown 'at I 5,.and imparting a slight, normally retained, bow to the sheet material intermediate at l6 (Fig. 4). This causes the crimps, as shown each edge section or panel of the sheet to havea three-point bearing in the groove, as indicated.

dition to facilitating movement This feature, in adof the sheet edges in the grooves, tends to prevent looseness and rattling of the cover sheets also to prevent buckling of in the grooves and the sheets when being opened by pressure applied to their top ends.

In the present instance, the extended entirely across the crimps and bows are cover sheets, as this is found to present a very attractive appearance to -the covers and cabinet as a whole.

We wish it understood that our invention is not limited to any speciflc construction, arrangement or form oi the parts, as it is capable of numerous modifications and changes without departing from the spirit of the claims.

Having thus described our invention, what we claim asnew, and desire to secure by United States Letters Patent, is:

1. A cabinet having cover guiding grooves in opposed walls, and a cover of resilient sheet material of cellulosic nature, having its opposed side edges mounted for sliding movements in said grooves, said edges each having successive crimps spaced lengthwise thereof with each crimp oi less height than the thickness or the groove in which it travels, the sheet materialbetween each succeeding pair 01' crimps being bowed to have central yielding bearing contact at its convex side with one wall of the groove and to cause the crimp portions at the ends oi! the bow to have yielding bearing contact with the opposite wall of the groove, the bowed portions being free to expand lengthwise of the cover when compressed.

2. A cabinet having cover guiding grooves in opposite walls, and a cover of resilient sheet material or cellulosic nature, guided at its edges for sliding movements in said grooves, and having a stiffening bar at each end, one of said bars having a slot therein in which the respective and edge of the sheet is anchored and having guide pins projecting from its ends into the grooves.

3. A cabinet having cover guiding grooves in opposite walls, and a cover of resilient sheet ma terial of cellulosic nature, guided at its edges for sliding movements in said grooves and having a stiflening bar at each end, one of said bars bein of angle form in cross-section and constructed of sheet metal with the metal at the outer edge of at least one flange doubled back upon the flange and clamping the adjacent edge of the cover sheet thereto, one flange of said angle bar being projected at its ends into the grooves.

4. A cabinet having opposed side members, and a bottom member rigidly connecting the side aioasso members above their lower edges and terminating short of the ends of the side members, said side members each having a single guide groove in its inner face extending lengthwise of the side member adjacent to its upper edge, thence curving downwardly and inwardly around and under the respective ends of the bottom member and lapping beneath said bottom member, one

end of the groove opening without the bottom edge of the respective side member, two cover members of flexible sheet material threaded at their edges into grooves through the open ends thereof and being oppositely movable-to opened and closed positions, and removable stop means in'the open end portion of at "least one of said grooves.

5. A cabinet having curved cover guiding grooves in opposed walls, a sheet-like cover of cellulosic nature having its opposed side edges mounted for sliding movements in said grooves,

, said edges each having successive portions formsaid cover having crosswise extending stiffening crimps and a bowed portion between each pair of crimps, said crimps at each end bearing against one wall of a respective groove and each bowed portion bearing at its convex side against the opposite wall of the groove, said bowed portlons being maintained slightly compressed from normal by the groove walls, whereby said crimps and bowed portions have opposed yielding engagement with such walls.
