11 Claims.

This invention relates to ready-bound crates and is an improvement upon the invention described and claimed in the co-pending applica-- tion of John Ekern Ott Serial No. 572,905, filed .3 November 4, 1931, in which there are disclosed a number of forms of ready-bound crates made up of separate Walls or wall sections which are surrounded by endless metallic binders adapted t permit the wallsto be collapsed or folded upon each other and to be put under tension when the walls are unfolded into box or crate-forming relationship so that they then hold the Walls in proper assembled relation. In said application, the separate wall sections are shown as having an overlapping relationship when they are unfolded to form a box or crate, that is, one end of each wall section abuts against the lateral side of the end portion of one next adjacent section, whiie the other end of `the rst mentioned section overlaps the end of the other next adjacent wall section. The present improvement is based upon the discovery that`the advantages of the invention cf said application may be obtained inra box or crate in which the adjacent wall sections abut against each other along diagonal lines to form what is known as a mitered joint. The principal object of the present invention is to provide a ready-bound box or crate comprising a plurality of separate Wall sections which are surrounded and held in assembled relationship by one or more endless metallic binders which are adapted to be put under tension when the walls are unfolded and to be retained under tension in the normal box or crate forming relaticnship of the walls. Another object of the inventicn is to provide an improved ready-bound crate made .up of a plurality of separate wall sections surrounded by one or more-endless metallic binders which engage notches formed in the 40 wallrsecticns at diagonally opposite corners of the box or crate so that when the walls are unfolded. the endless binders are put under tension to an extent proportional to the depth of these notches. Other objects relate to various features of construction and arrangement which will appear more fully hereinafter.

The nature of the invention will be understood from the following specication taken with the accompanying drawings, in which three embodiments are illustrated. In the drawings,

Fig. 14 is a perspective view of the outer walls of a crate made up of the wall sections illustrated in Figs. 11, `12 and 13.

In Figs. 1 to 6, inclusive, of the drawings there 5 is illustrated a form of the present invention in which a crate is made up of four complementary vertical walls having mitered joints at their corners and having their upper and lower edges secured to the top and bottom walls to form the completed crate. 'I'he four vertical walls of the crate are surrounded by a pair of endless metallic binders and, for convenience in shipment from the crate or box manufacturer, these walls are collapsed or folded upon each other so that they occupy little space and may be shipped in large bundles. When the user of the crate is about to fill it for shipment, these collapsed walls are unfolded, thereby putting the surrounding metallic binders under tension and then, after attaching the bottom wall to the vertical walls, ihe crate is filled in readiness for the application of the top wall or cover which may be secured thereto by nails or the like. It is ordinarily desirable to form the vertical walls as members of identical construction since they may then be interchanged with each other and any group of these walls may be selected for a particular crate, but the principles of this invention may, of course, be applied to crates or boxes of oblong horizontal cross-section. The walls illustrated in the drawings are of skeleton form adapted for use in forming a crate but they may have any desired form and may be constructed of a wide range of materials such as sawed wooden shook", veneer, plywood, wallboard, paperboard or sheet metal.

As illustrated in Figs. 1 to 6, inclusive, the imf proved crate comprises four identical wall sections 25 each of which is made up 0f a plurality of horizontal members 26 united by vertical members 21 which are secured thereto by nails or other means. 'I'he vertical members 21 may also be united by a diagonal cross brace 28 and the extreme upper and lower ends of the vertical members 21 preferably have nailing strips 26 secured thereto. In this instance, the horizontal members 26 are located on the outer sides of the vertical members 21, two of which are located adjacent the ends of the members 26. 'Ihe edges of the outermost vertical members 21 and the adjacent projecting ends of the horizontal members 26 are beveled along diagonal lines as shown at I0. Each of these beveled surfaces 60 preferably makes an angle of 45 degrees with the adjacent vertical faces of the wall section on which it is formed so that all four wall sections are of identical construction. When the four wall sections which make up the outer walls of one crate are folded upon each other as shown in Figs. 2 and 4, the beveled surfaces 30 diverge from each other on opposite wall sections. These wall sections are surrounded when in the collapsed condition with endless binders 3| which, in this construction, are illustrated as fiat steel straps having their overlapping ends united by means of a metallic seal 32 which may be of the form described and claimed in the United States patent to Ralph H..Norton No. 1,260,016, dated March 19, 1918.

These flexible binders 3i are arranged to engage notches 33 which are formed in the outermost vertical members 21 and in the ends of the horizontal members 26 of each wall section, midway between the upper and lower edges of the horizontal members 26. These notches 33 extend horizontally inward from the outer ends of the -horizontal members 26 and terminate at their inner ends in inclined surfaces 33a formed partly by seals $2 or the like, they arersecured to the horizontal members 26 by staples 34 which are preferably arranged to permit the binders to slide freely through them. The length of each binder Il, when it is applied to the collapsed wall sections as shown in Figs. 2 and 4, is such that when these walls are subsequently unfolded to the rectangular relationship shown in Fig. 6, the binder is put under tension and then serves to maintain the wall sections 26 in that rectangular relationship with the beveled surfaces 30 of adjacent wall sections contacting with each other. It will be seen that when the wall sections 26 are unfolded from the relationship shown in Figs. 2

and 4 through the intermediate position shown corners of the crate, that is, at the inner ends of the sections 26, as shown in Fig. 4, the wall sections fold upon each other. about the outer edges 30* of the beveled surfaces l0 which may preferably be cut of! as shown at 30h to avoid sharp edges at these points and to bring the aligning wall sections somewhat closer to each other when they are in their collapsed relationship. When the wall sections are unfolded with the inner ends of aligning sections pivoting upon each other about the surfaces I6", the binders 3| are bent at these points and are somewhat elongated or stretched in passing to the final position shown in Fig. 6 so that they are thereby drawn taut. Inasmuch as the diverging surfaces 30h at the outer ends of the collapsed sections, as shown in Fig. 4, move toward eachother in passing toward the unfolded relationship shown in Fig. 6, the binders 3| would be loosened by the unfolding operation if they were passed completely around the outer ends of the horizontal members 36 and it is for this reason that the notches 33 are provided. These notches preferably extend inwardly so that the inner vedges of the surfaces 33* are located at approximately the inner edges of the surfaces 66 or slightly inward therefrom so that when the walls 26 are unfolded, the diagonal portions of the binders will 'not intersect the interior space of the crate but by increasing the depth of these notches 6I, a greater degree of tautness of the binders 3l may be obtained.

When the wall sections 26 have been unfolded to the relationship shown in Fig. 6. the binders 3| are rendered taut and maintained in that taut condition so that the surfaces 30 at the corners of the crate are maintained in contact with each other and the vertical walls are held in position to form a rectangular enclosure. These walls. are then in position to be secured to the bottom wall 36 and the top wall 36 which may be constructed as shown in Fig. 3. Each of these walls comprises a pair of longitudinal members I1 secured by nails or the like to transverse members 86 which may also be connected by diagonal members 36. All of these members are initially nailed together and are then applied to the vertical wall sections 26 to which they are secured by nails Il passing through the nailing strips 2l and also through the ends of the vertical members 21. The bottom wall 36 is rst applied tothe vertical wall sections 26 and then, after the crate has been lled with the article or commodity to be shipped therein, the top wall 36 is nailed in place. The top and bottom walls, being of identical construction. are interchangeable with each other and may be shipped in bundles so that they occupy little space. In this Way, large numbers of crates made up of the outer walls 25 and the bottom and top walls 35 and 36 may be shipped from the manufacturer to the user in such condition that they are ready for use merely by unfolding the outer walls and securing the top and bottom walls in place by nailing.

In Figs. 7, 8, 9 and 10 of the drawings, there is illustrated the application of the invention to a modified form of crate in which the vertical and horizontal members are of unequal thickness. Owing to the mitered construction at the corners, this unequal thickness of the members of which the Walls are formed does not affect the actionof the unfolding operation in rendering the flexible binders taut. In this form, the vertical walls 45 are made up of horizontal members 46 of greater thickness than the right angularly disposed members 41 to which they are secured. The vertical members 41 are located adjacent the ends of the horizontal members and the outer edges of both members are mitered to form vertically extending beveled surfaces 48. These surfaces 48 are inclined to the adjacent `vertical surfaces of the members on which thei7 are formed at angles which are preferably 45 degrees so that the edges of all of the sections are similar in form. When the walls are in the collapsed relationship shown in Figs. 7 and 8, metallic binders 50 are placed around them with the overlapping ends of each binder secured together by a seal 5I or the like. These binders are secured in sliding engagement with the middle portions of the members 46 about which they pass by means of staples 52 and they are arranged to engage notches 53 which extend inwardly from the outer ends of the wall sect-ions 45 when these walls are collapsed as shown in Figs. I and 8. Each notch is bounded at its inner end by a beveled surface 53a which preferably makes an angle of 45 degrees with the adjacent vertical surfaces of the members 46 and 41 and which makes an angle of 90 degrees with the beveled surface 48 formed on the end of the wall section. The inner margin of each surface 53a is preferably located in proximity to the inner margin of the adjacent surface 48 and when the binders 50 are initially placed around these collapsed wall sections, the binders are substantially taut although there may be a small space between the inner ends of the adjacent wall scctions 45 which may be cut off as shown at 48a to prevent sharp edges at the outer ends of the inner inclined surface 48. With this construction, the binders 50 are drawn taut when the Wall sections 45 are unfolded from the relationship shown in Fig. 7 to that shown in Figs. 9 and 10. Nailing strips 54 are preferably secured to the upper and lower ends of the vertical members 41 for convenience in securing the outer wall sections to top and bottom Walls whichv may be of the form illustrated in Fig. 3.

collapsed relationship by flexible binders 6U which have their overlapping ends connected by a seal 6| and which are also secured in sliding engagement with the wall sections by staples 62. The youter ends of the wall sections are provided with notches 63 which are formed partially in the vertical members 51 and partially in' the ends of the horizontal members 56;- These notches are bounded at their inner ends by surfaces 63a which preferably make angles of 45 degrees with the adjacent vertical surfaces of the members 56 and 51 and which preferably terminate at their inner edges adjacent the inner edges of the surfaces 58. 'I'hese parts are adapted to operate as in the forms of the invention previously described so that when the walls are unfolded, as shown in Figs. 13 and 14, the binders 60 are rendered taut and are-adapted to maintain the walls in their proper assembled relationship. 'Ihe upper and lower ends of the vertical members 51 are preferably secured to nailing strips 64 which are adapted to facilitate the application of top and bottom walls secured in place substantially as s hown in Fig. 3.

Although three forms of the invention have been shown and described by Way of illustration, it will be understood that it may be constructed in various other embodiments Within the scope ofthe appended claims.
