29, 1929. Serial No. 389,291..

lh'ese improvements relate to containers in the form of drawers associated with each ther in a cabinet and designed to hold such eet material as tracings, blueprints, etc. round in drafting roonis.

T his application is a division of my copendmg application filed August 1, 1928 as Ser. No, 296595 on container for relatively large sheets.

One object or" the invention is to reduce the wastage or" space in filing cabinets for such material. It is found inconvenient tOllfillCllG one bunch or mass more than approximate ly one hundred sheets or" the kind referred to. The practice prior to my inventions has been to file that number of sheets in drawers not less than two inches deep and thus considerehly more than hall of the drawer space is wasted. According to these iin rovelnents the depth oi the drawers may e reduced greatly, and in my practice their depth is one inch.- A sheet-metal drawer having only one-inch deep sides and ends and having large horizontal dimensions involves considerations of construction not present in say a two inch drawer, and one feature of the present invention is directed to drawer construction,

l hen these drawers contain the practical- 1y permissible amount ofsheet material they are quite heavy, and another feature of the invention is directed to ease and convenience in operation.

in the accompanying drawing Figure 1 shows fragmentarily in side elevation a pin rality of drawers in a cabinet also fragmenshown; Fig. 2 is a fragmentary top plan of any one of the drawers of 1" 7 F 1g. 3 is further enlarged and longitudinal sectional view as on the line 33 of end wall 10 and side walls 11 while the front remains open for the insertion of the drawers. The adjacent ones or. these drawers marked respectively 14: to 22 inclusive are in close association with each other and are arranged one above the other in series. They are carried for forward and rearward sliding movements by guidingand-supporting means in the form of angle irons 125, seen in cross view in Fig. 5.

Each drawer illustrated has bearing menihers, preferably antifriction elements, shown as rollers 26 and 27., each thereof extending alcove the plane of the surfaces defining the top of these open top drawers respectively The drawer is shown as being drawn outwardly to some extent. Note that the roller 26 of the drawer 20 is in contact with the suhstantielly fiat bottom-wall Q8 of the drawer above it marked 19, and that the roller 27 of A drawer very easy.

The guiding-and-supporting elements 25 are so arranged that they are just about or harely in contact with the side marginal portions of the drawers respectively when the drawers are in closed position, as they are for the most part in Fig. 1, whereby both the rollers 26 and 27 of any given drawer are in ctual contact with the bottom walls respectively when the drawers are in closed position, The aim in this respect is to have the weight of the respective drawers on the rollers, but

with the angle iron cleats as 25 so substantially close to the under surfaces of the respective drawers that when any drawer is removed wholly or partially from the cabinet the drawer above will immediately rest on the supports as 25.

In the preferred arrangement the rollers are at the extreme end portions of the drawers -wnere there is strong reinforcing. That arrangement has other advantages but it is clear that rollers could be positioned along the sides.

The close arrangement of the cleats as 25 with the margin of the drawers is desirable further to prevent sagging of the drawers through a period of time. If the top surface of the rollers 26 and 27 be but slightly higher than the sliding surface of the cleats 25 next above them respectively the desired result will he obtained. When the drawer is withdrawn 2. consider his distance the over-balancing of the front end with respect to the rear end brings the roller 26 more strongly in contact with the bottom of the drawer above.

Each drawer has a pair of handles or pulls 29 secured as by screws 29a at the front end.

Fig. 2 shows that there are three such rollers 26 and three of the rollers '27 at spacedapart intervals across the rear and front marginal portions respectively of each of the drawers. it has been mentioned that these drawers are of very considerable size in the iore-and-att and lateral directions, and such a plurality of rollers as shown by Fig. 2 ishighly advantageous in the larger size drawers. More narrow drawers would suitably have two pairs of such rollers, while it is conceivable that a peculiarly narrow yet long drawer might be suggested for a particular purpose and in which a single roller at the front andrear would sufhce.

in the drawer construction illustrated the bottom Wall 28 is turned up to form side Walls as 30, the end wall 31 and the front wall 32.

Referring to the right hand end of Fig. 3 a channel forniedfrom sheet-metal having a normally vertical part 34, a top part 35, and a bottom part 36 fits upon the bottom Wall 23 at 28a and upon the end wall 32. The bottom wall 23 is pressed inward slightly at 28a:- to accommodate the flange-like part 36. This reinforcing member 34-3536 is strongly secured to the adjacent parts as by spot-welding, and this spot-welding is done before the reinforcing member next to be mentioned is applied. This further reinforcing member has a bottom flange-like part 38,a vertical part 39 and a forwardly extending part 40 reaching to the vertical end wall 32, and the upper walls and overlap each other to their full extents respectively. This auxiliary support 3839-4O is spot-welded to the bottom 23. It may also he spot-welded to the part 35, but I find that to be unnecessary where I have a plurality of screws, shown at 41 Fig. 2, holding the roller frames. these screws being threaded into the upper flange 40.

The construction at the right hand endv of F 3 as thus described provides a hollow rim substantially rectangular in cross view and extending from side to side of the drawer at its front end. Assuming the drawer of Fig. 3 to be one inch in height, the fore- ,and aft proportions of the rim are indicated,

Note that the bottom wall 28 is strongly reinforced at its front end portion by the flange- like parts 38 and 36 spot-welded to the bottom 28.

Turning to the left hand end of Fig. 3 I

the end wall 31 is turned rearward to form the flange-like upper wall 310:. (See Figs. 2 and 4.) There is rigidly secured to the wall 31 a channel iron of sheet-metal having a vertical part or base 43, a lower flangelike part 44 and an upper flange-like part 45, the flange 44 being on the plane of the bottom 28. These upper and lower flanges are parallel with each other and extend, as does the base 43, from side to side on the end Wall 31, the base 43 thus being coextensive with the wall 31.

The upper flange 45 interflts with the top wall 310: and is preferably spot-welded thereto at intervals. lVith the double thickness of metal at the top, namely the flange- like parts 31a and 45, taken with the rest of the construction shown the strength of this reinforcing member is suflicient.

Turning to Fig. 5 showing the construction at the sides of the drawer, secured to the side wall 30 is a reinforcing member substantially rectangular in cross view and having a normally vertical wall 48 coextensive with the wall 30, a top wall 49 and a bottom wall 50, the upper and lower walls 49 and 50 having extensions 511 and 521 respectively which are on normally vertical lines and are directed toward each other, but they do not come together, leaving a gap at 54 through which the electrode is inserted for spot-welding the walls 48 and 30 together. The flanges 511 and 521 strongly reinforce the construction and the reinforcement thus provided for the sides aflords the desired strength and rigidity.

The roller construction is the same at both ends and will be given the same reference characters except for the rollers themselves. There is arectangular open frame 60, Fig. 4, having side extensions 51 through which the screws 41 project to be threaded into the flange 45 at the left hand end of Fig. 3 and the flange 40 at the right hand end thereof. The frame fits between the walls 32 and 39 the right hand end of Fig. 3 and fits against the base 43 at the left hand end of that figure. These frames 60 therefore reinforce to some extent the rest of the construction. The rollers 25 and 27 are mounted on shafts 63, Fig. 4, extending rotatably through the uprights of the frame 60.

Such a shallow drawer not only effects savings in construction but, importantly, in'the filing space necessary for a given number of blue-prints, tracings, and the like, this latter being a feature of unusual importance when the hundreds of thousands of such. sheets to be found at a given engineering oflice are considered. According to my various imbeing turned upward, said extensions being directed toward each other and having their ends spaced from each other.

91A shallow sheetanetal drawer c01nprisingla normally horizontal and flat bottom wall, side and end walls upturned from the bottom wall, and a reinforcing frame memher at each of the side and end walls, each of said frame members having a top wall, a bottom wall and a side wall, the side wall of each of the frame members being rigidly secured to'the adjacent wall upturned from the bottom wall.

10. I'ncombination, two fiat-bottom opentop drawers arranged one above the other, the lower drawer having a roller arranged to rollupon the bottom of the upper drawer when the lower drawer is moved outwardly -relative'tothe middle drawer and the lower drawer having a roller arranged'to be in contact with the bottom of the upper drawer when the upper drawer is moved outwardly relative to the lower drawer.

11. WValls forming an open-front cabinet, a plurality of drawers one above the other in aseries in the cabinet,-'eacl1 of said drawers having bearing elements in contact with a next adjacent drawer of the series, the arrangement providing that one drawer con1- inunicates its weight through bearing elements to the drawer next below it, and means for supporting the drawers respectively whereby any given drawer is sustained when the drawer below it is withdrawn.
