.BOX-WALL-FORMING INTEGER.

Application filed December 24, 1927. Serial No. 242,400.

The object of this invention is to provide an improved box integer from a plurality of which any or all of the wall portions of a box may be formed.

The device of my invention is especially designed and adapted for the construction of fruit and anykind of shipping box where economy of cost and lightness of weight are important.

One of the features of this invention is to provide a box wall forming integer composed of a frame and a panel, and wherein the frame is primarily relied upon to take the load and wherein the panel is primarily a closure for the frame.

A special feature of my invention resides in novel means for rigidly uniting the bars, composing the frame, into a rigid frame structure, and also functioning to retain the panel in assembled relation with the frame.

A further feature consists in a novel frame structure provided with means forfioatingly holding the panel in position, thereby not only avoiding the necessity of specifically fastening the panel but also permitting the latter to be set in place with suflicient clearance so that shrinkage or swelling of the panel can take place without rendering the latter defective in the performance of its.

function, as a closure.

. 7 An important feature consists in the novel construction whereby one set of bars may be made of uniform cross section throughout their length, and whereby necessary alterations of cross sectionare wholly confined to the remaining set of bars.

My invention has many other features and objects which will be more fully described in connection with theaccompanying drawing and which will be more particularly pointed out in and bythe appended claims.

" In the drawing:

, Like characters of reference designate similar partsthroughout the difierent figures o 1 the drawing. I g

As shown, my improved integer includes a frame which is made up of what I will ar-V bitrarily designate as frame and panel bars, although this is a designation primarily adopted for convenience in facilitating a clear description of the frame because as matter of fact, all the bars are frame bars. l-iowever, in this specific form of the inven tion, I have shown a set or pair of frame bars 1, disposed in parallel relation and havmg each a cross section which is uniform throughout the length thereof. The ends 2, of said bars are adapted toact as tenons, as

will presently be described.

The remaining set orpair of bars, which Ifwillterm the panel bars, are designated at 3, and while they are shown to be of greater length than the frame bars 1, this is a mere incident, as in many cases, the two sets of bars may be of the same length, or may vary widely in length. The ends 4, of bars 3,:are

mortised at 5 and 6 in a manner to receive 7 the tenon ends 2 and form a'shouldered engagement, as clearly shown. It may be stated that this mortised reduction of bars 3, is uniform across the thickness thereof thereby greatly simplifying the operation as compared to converging or other tapered forms of mortise and hence avoiding the necessity of carefully shaped parts. As thus far described, therewould be nothing to hold the bars 1 and 3, in a single plane in which they are shown disposed, and the device, as thus far described, is clearlyan open frame. It is now informative to state that while the frame bars 1 and 3, are relatively narrow in width and relatively slight in thickness, thereby enabling me to make, them of trims and edgings, still, they are relatively heavy as compared to thebalance of the integer and are designed to take all the load and strain. 7

I will next describe the means and manner in which I close this open frame and in order formed on both bars 3, consists of a shoulder 7. and an abutting wall 8, the two forming what might be termed a panel seat. It is a featureof the invention to make this seat only deep enough to substantially correspond to the thickness of the closure used, and further, these panel seats only extend between the mortises, or specifically, the shoulders 6, thereof. The inside edges 9, of bars 1, are not in any way modified, as will be seen by reference to Fig. 2. i

As a closure for the open frame, I employ a panel 10, which in practice, may be a very thin sheet of veneer that is. not. designed. to take any major stress or strain and is merely capable of forming a closure and st. raining such: bulging stresses as the contents may impose. hen this closure is of wood, or any material that shrinks or swells, the constion ispreferably arranged so that the gran terminating ends 11 will engage the panel seats, it being understood that the grain runs vertically of the panel shown and toward th ends 11'. I also-cut the panel 1 0 so that a material. clearance will be present between the ends-L1,. and the shoulders i", of the panel seats thereby making full allowance for swelling of a wood panel Without permitting the same to bulge, the end clearance shown preventing bulging. TllQiSldC edges 12, which are disposed abreast of the inner edges 9 of bars 1, neednothave as much clearance but a slight clearance is afforded to take ample care of such lateral swelling as may occur. It will be noted that the panel 10 fi s flush with the panel. side of the frame and that the panel is freely set in the frame and is not anchored or in any way rigidly secured tln-reto but is merely laterally engaged 'ith and structurally supported in and by the frame.

I will next describe an important feature ofmy invention which interdependently coacts with the frame forming bars and with the panehto form a complete structure.

I have shown means for rigidly securing theframe and panel bars in frame forn'iing relation, and as shown, said means is in the form of devicesfor each corner of the frame and as all of said devices are alike in structure and function, only one need be described in detail. Referring to Fig. 5, said devices are'in the form of U-shaped staples or clips each having abight 13 and inwardly bent stapling ends 14. While the frame is under coniipressioir in such a manner as to very tightly hold the bars in the position shown in Fig. 1, a staple clip is driven into both sides of each corner of the frame with the stapling the sides of the bars, as clearly shown in Fl 4.. Furthermore, thiselongated engagement of the bights 1'3 with the bars 1: and 3,.functions mostetfectively to hold the bars against displacement from. a. single plane. It will alsobe noted that the clips extend diagonally across the corners of theframethereby holding themortised andtenon ends in firm engagement.

Preferably before the clips are attached, the panel 10 isdisposed in the frame as shown in Fig. 1. Now it is a feature of this invention-toso dispose the clips that the bights 13, thereof will extend across portions of the panellll, preferably across corner portions thereof, as shown. Hence, the clips perform the dual function of rigidly connecting-the bars in frame forming relation, and also, holding thepanel in assembled relation with the frame. Thus it will be-seen that I avoid not onlythe extra operation but alsothe matm'ial necessary to specifically anchor the panel lO to the frame.

It will now be clear that the-panel is floatingly mounted in tlieframeand that by reason of the end clearance-provided, I not only avoid the necessity and expense of cut-ting the veneei to' accurate lengths, but I can use veneer successfully irrespective of shrinkage or swelling either longitudinally orlaterallv. Where the panel is made of non-shrinkable material such as card-board, it may belitted more snugly, even tightly, in thefranie, although the function and interdependence of the parts would still bc' present as in either case, thepanel would be frictionally held in assembled relation with the frame.

By means of this construction, I can use material for the frame of a very narrow width and a very slight thickness and still make a frame that is capable of taking all the major stresses; By reason of the fact that the panel isdes'irably flush with one side face of the frame, the biglits 13 serve-to engage and hold the panel so close to the re cessed portions 8-, that a very compact and secure structure is afforded;

irrespective of the paneL'I consider that the frame structure itself, is pate'ntable.

I have termed the" device of my invention a box wall forming integerforboxes, and in this connection, I use'the-term wall generi- Cally, toincludebox tops, bottoms, sides, ends and partitions. In some of these integers, especially the partitions, the panel may be duplicated to present flush faces on both sides of theframe. i

It will nowbecl ear that by merely making up the integers in the proper sizes, the walls of an entire" box, or in otherwords, an entire box may be made with these integers,thebars thereof forming convenient and stable nailing stock.

It is believed thatthedevice of'iny invention will be clearly understood from the foregoing description, and While I have herein shown and described one specific formof my invention, 1 do not wish to be limited-thereto except for. suclilimitations as theclaims may import.
