22 Claims.l (Cl. 229-9) AThis invention relates to the fabricationv of receptacles, and particularly oftransfer or storage illes, suitable for receiving and storing les oi' correspondence and other papers, and is a division of our copending application Ser.' No. 666,895, filed April 19, 1933. i

It is the general object of the invention to provide an improved construction for receptacles 0f the type indicated in which such receptacles are supplied to the consumer in knock-down 'condition lto be erected and assembled by him before use.

More speciiically, it is an object of the invention to provide a transfer orstorage ille of the collapsible or knock-down type, and particularly a drawer -member which is 'adapted to slide within a casing and is of extremely simple form and can be easily erected and assembled with a few very simple movements requiringno study or ingenuity on the part of the purchaser.

It is also an object of the invention to provide a drawer element for storage illes which is made of inexpensive materials, including paper board, thin sheet-metal, wire and the like as preferred components, combined in novel forms which pro-v vide adequately for strength with unusual lightness, and for a desirably low intlammability, with an appearance simulating, when assembled, an f all-metal structure, but at much lower cost for materials and labor in fabrication and installation. In particular it is an object of the inven- 'tion to provide a drawer member whose front wall has -a metallic surface which, in addition to imparting to the .assembled drawer and casing the appearance, from in front at least, of an allmetal structure, provides the moisture-proof -and neat, abrasion-resisting surface characteristic of metallic sheets or layers.

An additional object of the invention is to pro- -vide a metallic or metal-faced front wall for sliding, drawers of paper andv similar materials and at certain limited areas, thereby combining they advantages of paper board, namely lightness and inexpensiveness, with the strength, durability and neatappearance of sheet-metal.,

Another object of the invention is to provide.

. an improved drawer member of knock-down construction combining elements so connected at the place of manufacture as to involve a minimum :elty will be set forth in the appended claims.

drawings, in which of eifort in erection by the consumer, and having connecting devices of simple but very sturdy components, so that their manipulation requires no. particular degree of mechanical knowledge, and when erected are capable of withstanding heavy g, loads and hard usage without requiring any un'- usual degree of care. 4

It is a still further object of the invention to provide a reenforced paper ille construction wherein locking or securing means are provided, which are so constructed and associated with the reenforcing parts .of the structure as to engage and interlockwith the same in the assembled condition of vthe receptacle, vthereby insuring a iirm and wear-free anchoring and interlocking of the' securing means with metallic or similar strong and rigid structure. Other objects of the invention will appear from the description following and the features of nov- 20 Two embodiments of the invention are illustrated by,way. of example in the accompanying Fig. 1 shows a pian view of a blank used in the fabrication of the drawer or .container which is adapted-to be inserted into a suitablecasing, the blank being shown in its initial stage of fabrication.

Fig. 17 is an enlarged cross-section through the paper structure of the drawer showing the corrugated paper construction.

While the drawer structure about to be described is designed primarily for use in combination with a casing of the type disclosed in our application Ser. No. 666,895, it is adapted for use in any eld for which it is suited by the nature of my improvements.

The form of drawer element selected for illustration and description is shown in completed form in Figs. 6 and 7, where it is designated generally by the reference character D,A and comprises a body portion made preferably of a nonmetallic material such as corrugated paper board, with a front wall having an all-over facing 35 of sheet-metal which is extended around the edges of the front wall portion 36 of the body to form a metal binding 31.

In fabricating a drawer element of this type, we preferably make use of a blank which is shown in its initial stage of manufacture in Fig. 1, being there designated generally by the reference character 38, the material being of any suitable character, such as stout paper board.

This blank is scored longitudinally, as at 39, and transversely as at 40, 4|, to dene the junctions between the bottom 42 of the drawer and the side walls 43, the 'front wall 36 and rear wall 44 thereof,

Thecorner material at each of the front corners is cut away, as shown, leaving the front wall 36 projecting beyond the ends of the side section 43, while the material of the rear flap 44, extendingv beyond the scorings 39, may be left integral with the rear wall, being severed from the side walls 43 by the slits 45. This permits these flaps 46 to be folded over, as shown in Fig. 3, and secured to the rear wall 44, as by rivets or staples 47, thereby constituting reenforcements of the rear wall. The flaps 46 may, however, be dispensed with, if desired.

The front wall is preferably increased in bulk or thickness by the addition of a ply of material Il, such as paper board, which may be riveted thereto, as indicated at 49, along the lower inner 'front edge, while its outer margin may be embraced within the binding 31 and so held firmly in place (see Fig. 3).

The margins of the side walls are each vpreferably provided with sheet metal bindings 50, for the purpose of reenforcement, resisting forces tending to cause collapse or buckling of the side walls, and also to serve as a mounting for ro'- tatably supporting the holding member'5i of U- shaped stiff wire having latch portions 52, 53 adaptedA to be engaged with cooperating portions of the rear end wall and. front en'l wall, respectively, as described hereinbelow.

The rear end wall is provided with a similar sheet-metal binding strip 54 which may, and

preferably does, have end extensions or wings 55,

with apertures 56 (Fig'. 8), through which the latches 52 extend in the assembled drawer, these wings serving as wear-resisting abutments, and also to stilen the structure. The latch portions 52 may be held yieldingly in place by the heads of suitably positioned rivets, or by equivalent means, as shown at 52a, and over which the latch portions 52 snap into nal position.

At the front end of the drawer element the hooklike latches 53 extend downwardly against a cooperating part 56 of the front wall binding, as shown in Figs. 9 and 11, when in operative'and assembled position. The part 56 is suitably apertured to receive the latch portion 53, as shown at 56a. y

The inner paper ply 48 is cut away as s' own at 58 (see Fig. l) and a rear metallic facing plate 48a is depressed, as shown at 60 (Figs. 3, 9, and 11) to afford clearance for the swingingmovement of latch 53, the indented metallicportion 6U serving also to protectv the paper section 36. The inner portions of the metal 'facing plate 31 are bent over the edge portions of the plate 48a, 36 and 48, the whole forming a neat, strong and rigid structure, to clamp therebetween the paperA sections as shown at 60a and 60h (Figs. 8 and The front sheet-metal face-of the drawer element is show n in Fig. 6 as offset forwardly at four points 6I, defining the apices of a quadrangle, to provide retaining means for an. index card; and said sheet metal face' may desirably be offset inwardly as at 61a to provide a recess in which is mounted swingly a bail or handle 62, for convenience in manipulation of the drawer. The handle may be pivotally supported in a clip 62a which passes through the whole front wall, as shown in Fig. 8, the free ends of the clip being struck downagainst the inner plate 48a.

The assembly of the drawer member just described will be clear from the foregoing andI may be briey described as follows: Beginning with -the structure in the condition shown in Fig. 3,

the front and rear walls are raised into the position in which they are approximately at rightangles to the bottom 42. The side walls are then bent into similar vertical position and the latch members 52 and 53 are inserted in their respective apertures 56 and 56a. As the contiguous edges of the walls are brought into engagement, the latch members are forced downwardly into the positions shown in Figs. '1 to 11. The latches 52 will snap into position after riding over the heads of the rivets 52a. The connecting bends 52h between the latch members and the longitudinal portions of the U-shaped locking members are of such length that the latch members engage firmly and closely against the respective retaining metal plates, so that the walls of the drawer are rigidly locked together. It will be observed that the-sev- .eral sections of the drawer are of simple configuration and the manner of their erection becomes immediately evident on inspection.

From the above it will be evident that the paper front wall section 36 serves as a-connecting member between the sheet-metal front wall structure 35, 48a and the bottom 42 of the drawer; however, other modes of connecting the metal wall to the drawer bottom will suggest themselves to those skilled in the art.

Figs, 12 and 13 show a form of wire holding means which is similar in structure and operation to those already described, having a shankportion 63 mounted rotatably in a metallic bind.

ing-strip 64 upon the upper margin of each side wall 65 of the drawer member. 4The latch portion it of this device is shown as of arcuate shape,

and is adapted to enter retentively into engage-- ment with an apertured portion G1 of the metal lbinding upon the adjacent portion of the rear In Fig. A14 we have shown the forward end ofthis ,holding member as providedf with a latch i9, adapted to swing in an armored recess 1l provided in the front wall 1| as already described, the latch being of resilient construction and arranged to snap into position to one side of a rivet or stud 11a. The free end of the latch is bent outwardly to facilitate engagement thereof for releasing the latch. In the embodiment of the invention shown in Figs. and 16, the fastening A or locking means shown in Figs. 3 to 14 are replaced by boltsV extending from the front to the rear wall of the drawer, and, like the locking means of Figs. 3 to 14, supported preferably within the reenforcing members on the upper edges of the side walls.- As shown in Fig. 1'5 the reenforcing member 12 attached to the upper' edge of each of the side walls I3 is provided with a laterally and inwardly directed hollow portion 13 which receives the stem of a bolt 14 whose angularly shaped head 15 is received within a similarly shaped recess in the front wall J6, while its opposite end is threaded to receive a nut 16 which bears against the rear face of the rear wall 44, 46, and preferably against the metallic reenforcement secured to such rear wall. In this way the foldable front, rear and side walls are rigidly held in assembled.condition,the locking means, as in the case of the previously described locking means being supported on andA engaging the reenforcing elements associated with the walls of the drawer.

Fig. 17 represents a section taken through the paper body portion of the drawer and illustrates the corrugated paper construction thereof. This corrugated paper construction is composed, as is known, of two outer paper layers^11 and 1B which are glued or cemented to an intermediate corrugated. paper layer 1il.y l

From the foregoing, it' will be seen that we have provided a drawer component of a ille structure which is characterized by simplicity, strength, lightness and inexpensiveness, and can be used with any suitable complementary casing structures. When a filing construction employing my improved drawer element is used as a unit, or in an assembly composed of similar units, the effect;

produced is that of an all-metal unit or assembly, when viewed from the front. VAs practically all of the edges of the receptacle are faced or lined with metal, the neat appearance of the assembly is retained indefinitely. Moreover, the receptacles are much more nearly fire-proof and moistureproof than lescomposed wholly of paper. The individual elements are lighter than all-metal elements of equivalent capacity, and are less ex pensive to fabricate, both as to material and labor. Y Y

In view of the factthat the front wall of the drawer does not have to withstand vertical com-V Y of corrugated or other paper forming the body of the front wall of the drawer, nevertheless in thin vmetallic facing is impervious to moisture, is fire-resisting to a certain degree, resists abrasion and preserves the neat, smooth appearance' of the drawer wall. Moreover, it will simulate the appearance of a solid ail-metal structure and to all intents and purposes will perform the functions of a thick metal structure in the front wall of a drawer while at the same time it will be oonsiderably lighter and cheaper.

'I'he knock-down form of the-drawer element renders it easy to transport in quantities, and as they occupy a minimum of space they can be kept in stock in large quantities by dealers, or keptin reserve at ofces where they are to be usedeventually.

If not needed, individual'units can be knocked down, and the office space thus saved can be used for other desirable purposes, the knocked-down units being retained for later expansion of the storage illes.

Variations from the specific constructions illustrated and described may be resorted' to within the scope of the appended claims without de,

parting from the spirit 0f the invention.
