Original application October 19, 1935, Serial No. 45,715. Divided and this application September 29, 1939, Serial No. 297,030 v 6 Claims. y(o1.45 77) My invention is a true division of application Serial No. 15,715,111ed October 19, 1935, Patent No. 2,200,319, issued Mayl l, 1940, and relates to collapsible and/or folding containers; and more particularly to novel construction of drawers and the like of this class and novel construction. of

theparts with which said drawers and. the like coact to facilitate movement of said drawer relative to said coacting parts.

-.In the movement of the drawers in-andout of thecontainer inwhich the draweris adapted to operate, it is desirable that as much freedom of movement as possible shall be obtained. The, patent application of which this is a division was a continuation in part. of my copending application Serial No. 693,841, filed October 16, 1933, Patent-No. 2,233,906, issued March 4, 1941, in which I have shown novel. construction. for facilitating the movement of a drawer in a collapsible casing, and of my copending application Serial No. 739,962 filed August. 15,1934, Patent No..

2,159,069, issued May 23, 1939, inwhich I have shown novel construction for facilitating the movement of a drawer in a foldingor collapsible cabinet. l

In the aforesaid applications, I have shown a substantiallyflat bottom drawer of fibrous sheet,

material with novel wheel and track construction. This construction is generally very efficacious in reducing the friction between the drawer andthe container, but I have found that with certain drawer loadings, the drawer bottom. will sag or bow an amount to permit the drawer bottom to make contact with the bottom of the casing unless the wheels and tracks or fails are so mounted bottom of the subjacent part. If the drawer bottom should sag under loading a sufficient amount.

to come into contact with the subjacent part,.the full benefit of my anti-friction mounting cannot be obtained.

I have found that where it expected to load.

the drawer in such a manner that, without a special construction, the drawerwould rub on the subjacent part when loaded, I may provide means in the construction to eliminate such action.

Moreover, I have found that I may combine various parts of the anti-friction member with reinforcing or connecting members and thus obtain an economy of construction through such combination of parts. I have also found that other economies of construction may be attained through certain novel rearrangement of parts which expedite the manufacture of my novel construction. I Y

as to hold the drawer some distance above they Accordingly, objects of my invention are to provide novel apparatus for and methods of moving drawers into and from its container on wheels or rollers; novel apparatus for and methods of mounting collapsible drawers, to be moved on wheels or rollers from and into a collapsible container; tracks secured to the container and/or f the drawer and rollers or wheels cooperating with said tracks for providing a, maximum freedom of movement of the drawer with respect to its container; novel drawer construction to reduce sagging of the drawer bottom upon the subjacent part; tracks combined with reinforcing and/or connecting members; improved construction atlecting manufacture.

There are other objects of my invention which together with the foregoing will appear in the detailed description following in connection with the drawings in which:

In Figure l, I have shown a form of folding drawer described in detail in my Patent No. 2,233,906 which has already been referred to. In this figure, the drawer I comprises the front wall 2, the inner front wall 3, the side walls 4 and 4', the rear wall 5, the inner rear wall 6, the side wall flaps 'I and I, and the bottom panel 8, together with front wall flaps 9, rear wall flaps III and I0, and tabs extending from each end of both of the side wall flaps. folded from a single blank of sheet material and, after folding, is held in assembled position by means of the Various flaps and tabs as described in my Patent No. 1,946,516.

This drawer may be used in connection with the collapsible container of the type described Patent No. 2,200,319. And where necessary, re-

This drawer may be infor-cing strips or tracks may be placed in the bottom of said casings to cooperate with the roller constructions hereinafter described.

In Figures 2 to 7, I have shown a further feamm which may be applied to my drawers, comprising wheels secured to the base or floor member thereof for riding on a track in the casing. As shown in Figure 6, a flat member 4| preferably made of metal may be provided with prongs stamped therefrom and may be scored to form a predetermined bending line at 43 and 44. At 45, the metal is punched out forming a pin support at the openings 46 and 47 for a roller when the metal is turned along the

scorings

43 and 44 into the form shown in Figures 4 and 5.

A pin 5| having its ends 52 and 53 of reduced diameter protruding through the openings 46 and 41. and provided with the

caps

54 and 55 carries the ring 56. Between the

rollers

56 and 57, the roller ball bearings 53 are supported for permitting a free rotation of the caster 59. The member II, after being formed into the shape in Figure 4, is secured to the inner and outerside walls of the drawer by its prongs as shown in Figures 2 and 3, the side of .member 4! coming opposite the inner side well being admitted therein through a suitable slot formed in the bottom wall.

Secured to the base of the casing is a member 48 (Figures 7 and 2) having the dimensions substantially equal to the inner dimensions of the bottom of the casing and having the tracks 49 and 56 formed therein at positions at which the rollers 59 will ride in the tracks. In a further form of my invention, these tracks may be constructed as an inherent part of the base or bottom sections of the casing, as will be described in further detail.

In a further modification, the wheel members similar to those shown in Figures 2. to 7 may be combined with track members on the drawer, and at the same time the track members maybe used to reinforcethe bottom drawer corners. Such modification is illustrated in Figures 8 t0 10.

Such a track may obviously cooperate with a roller on the casing in the manner set forth in my parent application above mentioned.

As shown in Figure 8, the drawer 50 is provided with the track members ISI provided with the track 62 adapted to coact with a wheel mounted upon the inside of a casing. The track member 6| has the

prongs

63 and 54 by which it may be attached to the drawer blank, the prongs 53 being applied to the side wall panel and the prongs 64 being applied to the bottom panel of the drawer blank. The track member BI is thus adapted to fit partly over the side wall of the drawer and partly over the bottom of the drawer. As applied to the drawer blank the side wall and bottom wall portion are in the same plane, but when the drawer blank is folded into assembled position, the track member BI is bent on the bending line 65 and forms an angle reinforcement for the drawer.

As shown in Figure 8 and in greater detail in Figure 9, a portion of the track member may be bent to form a channel having the flange 66 adapted to pass through a slot in the bottom of the drawer and to be fastened to the inside of the side wall of the drawer, as for instance by prongs 61.

At this channel shaped portion, the track member 6| has the punched out

portions

61, 68 and 69, the latter two openings being shaped to support the axle I0, and the hole 6'! being shaped to permit the wheel 'II mounted Within the channel portion to extend through the member 6| in order to cooperate with a suitable track, such for instance as that shown in Figure 13 which has already been described.

While in Figure 10, I have shown a wheel with plain bearings, it will be readily understood that a wheel having roller ball bearings as in Figure 5 may be used in connection with the track mem-- ber of Figures -8 and 9, or that a plain bearing may be used in Figures 2, 3 and 4 in place of the roller bearing shown in Figure 5.

In any event, it should be noted that the members maybe true rolling members or not as the specific need demands, and that rollers 58 (of. Figure 5) may be used as required.

In connection with Figure '7, I have shown that a track member for the casing may be provided on a separate bottom pad. Other types of pad 'members may, of course, be used as described in my Patent No. 2,200,319.

In Figures 11 to 15 I have shown the use of a plurality of flanges.

In Figures 11, I have shown a blank of sheet material I5I provided with suitable score lines to wall extension I to receive the flaps I when the drawer is folded into position. The bottom flanges may be provided with the cut out portions I63 to allow space for a wheel, which may be mounted on the flanges in a manner as will presently be described. The side Wall panel I52 is deeper than the side wall extension I53 by an amount substantially equal to the depth of the flanges I58. In this manner, when the blank is folded into position on its score lines, the extra depth of the sidewalls forms a portion of the flanges of double thickness shown at I58 in Figure 13.

The rear panel I54 may be provided with the wings I64, and the rearpanel extension may be provided with the wings I55. These wings, in the folded position of the blank are held in place between the side wall and the side wall extension, and act to hold the rear wall to the side walls.

When the blank is bent on the score lines 166 and I6I a flange is formed runningthe length I63 and the flange panel I69.

channel I14 as is shown in Figure 15.

coinciding with the score lines of said drawer of the drawer and extending downwardly along the center of the drawer bottom. This brings the two panels I56 in edge to edge relationship to form the drawer bottom as is clearly shown in Figure 13. At the same time flaps I59 are brought into abutting. relationship as is the flap The panels I51 may be united with each other in any suitable manner. Thus, they may be adhesively united and/or they may be united by the metallic channel I10 which may extend the entire length of the drawer bottom. In a similar manner, the side flanges I58, may be produced by bending the blank on the score lines HI and I12, and

, these flanges may be secured in place by the metallic channels I13 which may be provided with track portion I15. Also flaps I68 and the flanges panel I69 may be folded into face to face relationship with the back panel I54 and united therewith,,as for instance by the metallic The blank after the flanges have been'bent into place and properly secured, will be substantially the same form as the back member to be used with my metal faced front as described in my copending application entitled Drawer, Serial No. 45,711, and filed October 19, 1935, Patent No. 2,152,676, issued April 4, 1939. Such a metal faced front is indicated in Figure 12. This front may be united with the body. flank II by inserting the flaps I59 at the front end ofthe bottom I56 between the back I16 of the front pan-e1 and the metallic member I11. The metallic member I11 is then pressed down and clamps the front face to the body member, which forms the completed blank for the drawer which may be shipped in a substantially flat condition to be set up by the user without the need of any tools or additional parts.

As will be seen in Figure 13 and in greater detail in Figure 14, the channel I13 may be cut out as at I18 to accommodate the wheel I19 mounted on the axle I89 and extending below the bottom face of the channel I13, substantially in the same manner as has been described in connection with Figure 9. The openings I63 provided in the flanges, permit the wheel to operate in the plane of the flanges. A proper track may be provided in the casing for each of the wheels on the drawer.

While I have shown the drawer body as being formed from a single blank of material, I may construct the body from a plurality of blanks united with each other at any of the bottom flanges. Thus it may be seen that if the body blank is composed of three separate pieces ending where the score lines I12 are shown in Figure 11, these three pieces would be united into. a uniting structure at the flanges I58 by the metallic channels I13.

This invention is obviously capable of many and varied uses. I prefer, therefore, to be limited not by the specific disclosure herein, but only by the appended claims. I

I claim:
