16 Claims.

\ My invention relates generally to wire bound boxes and more particularly to box blanks having binding wire secured thereto, which are adapted to be folded or assembled so as to have the binding wires surrounding the completed box, and preferably running crosswise or in transverse relation one to another at certain points.

In the box making art, the common forms of boxes include the paper box, the nailed wooden box, the wire bound wood box, and the fibre or composition boxes. The paper and fibre boxes are used principally for light packing, while the wirebound wood boxes are used for heavy packing.

According to the present practice, the blanks forming the top, bottom and sides for wire bound boxes are constructed by joining a plurality of separate panels together with binding wire, then folding upward said panels on said wires as hinges to form the sides of the box, the last panel forming the top. End members are then inserted in the open ended structures so formed and nailed to the side panels, and the box is packed. After packing, the top panel is folded down and the ends of the binding wires on the side panelsare spliced together over it.

In accordance with my invention, both the side panels and end panels are fiexibly joined together by having binding wires attached thereto, i. e., two blanks are formed, a side, bottom and top forming blank and an end blank or blanks which are adapted to be assembled into a box, packed and sealed without resorting to any finishing operations other than splicing the ends of the binding wires together.

This improved box structure is adapted for use with wood, fibre or any composition material, and when completely assembled, the preferred form has the binding wires running crosswise, to provide a securely bound structure.

The principal object of my invention is to construct wire bound boxes of wood, fibre or like material, by utilizing a two blank structure, each blank having binding wires attached thereto and serving, partly or wholly, to hold its different portions together, said blanks being adapted to be readily formed into a box structure which can be packed and sealed without resorting to any end fitting, nailing or stapling operations.

Another object is to provide a bracing means for retaining the sides and ends of the box in a vertically assembled relation while said box is being packed.

Another object is to provide a wire binding on each of the box blanks, which bindings will pref erably cross each other in a transverse or diagonal relation when the blanks are assembled.

By my arrangement, I usually provide two blanks, one comprising a plurality of flexibly connected panels having binding wires secured 5 thereto, to form the bottom, top and side walls of a box, and another comprising two panels spaced a predetermined distance apart, also having binding wires attached thereto, to join same together properly spaced apart to form the end walls of a 10 box when assembled with the first blank. Such a box is formed for packing by either of the following preferred methods: by placing the bottom panel of the side wall blank over the intervening exposed portions of the wires joining the end wall 15 panels, then folding the end walls and two side Walls vertically upward and retaining same in said latter position by means of a hoop or other suitable means; or by placing a side panel of the side wall blank'against the intervening exposed 20 portions of the wires joining the end wall panels, then folding the end walls in place by swinging them like doors and joining the ends of the binding wire carried by said end wall panels over the other side wall. After packing, the projecting 25 portions of the body panels, forming the top (if it is a fibre box), are closed, and the wire ends projecting therefrom are twisted or spliced together. No extra nailing or stapling operations are required at the packers, all finishing operations being completed by a wire twisting tool, used 'to splice the free ends of the binding wires together. A box may be constructed, however, within the broad principle of my invention if made from a single blank properly wired, as will 30 be hereinafter explained.

Several embodiments of my invention are illustrated in the following drawings, in which,

Fig. 21 is a perspective view of a modified form of end blank in which more than two wires are shown as binding wires for the end panels, one of which wires is shorter than the other two, to permit said others to be drawn together at the center in diagonal relation, as shown, and

Fig. 22 shows still another modification in which one integral blank is used, being scored along the lines between adjacent panels.

In the drawings like reference characters indicate like parts.

for fibre box construction or any manufactured composition, such as paper, card board material or the like. The said box structure shown .in these figures of drawings comprises two blanks,

one, generally indicated by the reference character l0, forming the side walls, top and bottom, and another similarly indicated by I 2 for the end panels, which together are adapted to be formed into a box structure of the types shown in Figs. 1 and 9, ready for packing and closing.

' Each blank [0 is composed of a single sheet of material which is scored along lines indicated at '14 to provide a plurality of panels marked S, B and T, said panels forming the sides, bottom and top of the box respectively. Binding wires l6 are secured to one surface of the blank iil, by means of staples NJ, as shown in Fig. 5, or in any other convenient way, with the ends l8 of said wires projecting beyond the edges of the blank.

The end blank (Fig. 6) comprises two panels 2fl22, which are joined together in spaced relation by means of two or more binding wires 24-45, said wires being similarly secured to the surface of each panel by stapling or otherwise, as indicated in Figs. 5 and 7, and having their ends 25-28 and 21-29 projecting beyond the ends of the blank so formed. It will be noted that the wire ends 26-21 are preferably made longer than those of the wires 2829, for a purpose to be hereinafter described. Side tabs 3!), 39, and upper and lower tabs 32, 32 are added on these end panels to reinforce the box structure at the corners and may be made in any desired shape, the adjacent edges of tabs and panel bodies being outlined by scoring as shown.

Both blanks I E! and i2 are easily constructed by passing the panels in assembled relation through automatic box making machines. These machines apply the binding wires, staple the same to the panelsfand out said binding wires to the desired lengths as each blank is carried through. After the blanks are thus completed, they are adapted to be stacked in pairs, each comprising one end blank and one side, bottom and top blank, one above the other, for shipping, thus occupying only the floor space neces-- sary for the larger one of the two blanks.

At the packing plant, the blanks are easily and quickly formed into boxes ready for immediate packing, closing and sealing.

According to one method of assembly, the end blank is first placed in the position shown in. Fig. 7, then the panels S, B and T of the other blank are folded and placed over the wire portions 25-45 intermediate of the two panels Ml-- 22 of the end blank as shown in Fig. 8. Next the end panels 2B-22 are bent upward into vertical position with the side tabs 38 preferably passing inside of the side panels S, and the upper tabs passing outside of the top panels T, the lower tab being already located under the bottom panel B by the initial act of assembly. To retain the walls in this folded, box forming relation prior to packing, a hoop 34 or the like embracing element is slipped over the box, to hold the sides and ends together, in assembled position while the box is being packed, all as shown in Fig. 9.

After packing, the top panels T are folded together downward and the opposite ends |8-|8 of each wire it are spliced together as indicated at 56 in Fig. 11; then the end projections 26-2! of wires 2425 are drawn diagonally across the top of the box and joined to ends 28-49 by splic ing the end 26 to the end 29, and the end 21 to the end 28, as shown at 58 in Figs. 10 and 11.

Another and perhaps preferred and simpler method of assembly is shown in Figs. 1 and 2, in which the end blank is assembled with the side walls in such manner as to have the binding wires on the end panels pass around the side walls S, S of the box and thereby brace the sides as well as the ends in their assembled relation for packing, thus dispensing with the hoop 34.

It is obvious that, by means of the binding methods described, a stronger box can be made from the less expensive grades of fibre or paper stock, since the wire binding reinforces nearly all the corner edges of the box, and the diagonal wires provide additional bracing against lateral distortion, which is more effective than any produced by merely running the wires 24-25 parallel across the bottom of the box, as shown in Fig. 12. Diagonal bracing wires may also be provided at the bottom as shown in Fig. 13, by extending the length of the wires 24--25' between the end panels 2fl-22, to provide the necessary amount of slack to permit said wires to be drawn toward each other at the center, and twisted together. This latter operation is preferably performed when the binding wires are attached, by means of a twisting member on the box blank machine. With both the upper and lower diagonal bracing, the box will be strong enough to easily withstand the rough handling to which packed boxes of this character are usually subjected.

It may be desirable to permanently secure the panels of the end blank Ill to the other blank l2 before forming the box at the packers, and for this purpose I propose to secure each of the end panels 20-22, to the bottom panel B of the blank |2, by stapling the inner tabs 32 projecting from said end panels 2El22, at 33 to the bottom panel B, as shown in Fig. 20, or in any other convenient way.

If economy of space when packing the blanks for shipment to users, and if material consumed in making the blanks are not controlling factors, a firmly knit, easily assembled box may be produced from a single, integral blank Hill, as shown in Fig. 22, where the end panels 20 and 22 project from the sides of the body blank which is composed of the side, bottom and top panels S, B" and T, as before, the single sheet of fibre material being scored to form the lines of bending. Tabs or cleats (not shown) would be used as in the other modifications. The various panels would be bent up and over to form the completed box as before, after the binding wires had been fastened to them in proper position as previously described, the ends of all wires being spliced together, and some of them crossed as before. Such a blank would be passed twice through the same stapling machine or machines as are used for fastening the wires to the previously described blanks.

The two blank crossed wire method of construction may also be applied to box assemblies composed of other forms of blanks, such as are now used in wire bound boxes, crates and the like, said crossed wire arrangement involving an improved method over the present practice in wire bound box constructions.

According to the present practice of construct 5 ing wire bound wood boxes, the body blanks are fabricated in about the same manner as the body blanks of my invention, but the end panels are secured to the box by nailing or stapling, which operation is not required, by my method of n construction, now' to be described.

In Figs. 14 and 16, a body blank for a wooden box is shown, which comprises a top, bottom and two sides as indicated by the reference letters, T, B, and S, S, respectively, said panels be- 15 ing flexibly joined together by binding wires 40, which wires are secured to the said panels by stapling. The ends of said wires project beyond the edges of the end panels as indicated at 4|. Cleats 42 may be provided for the side panels as 20 indicated in Fig. 16, which cleats are joined thereto in a well known manner, and are preferably placed at a slight distance inward from the ends of the body panels to accommodate the thickness of the end panels, and to provide a ledge 43 projecting beyond the same when assembled, as shown.

While the above panel structure for a body blank has been referred to as made of wood, it is to be understood that fibre or other suitable ma- 30 terial may be substituted.

The end wall blank shown in Fig. 15 comprises two panels 44, 46, which are joined in spaced relation by having binding wires 4849 secured thereto, as in the construction of the end wall blank shown in Fig. 6, each wire projecting beyond the outer edges of the panels as indicated at 50, 5|, 52 and 53, the ends 50 and 5| preferably being longer than the ends 5253.

The methods of assembling the wooden box are similar to those employed with the fibre box previously described. One of such methods is clearly shown in Fig. 16, which method of assembly is to place the bottom panel B of the body blank over the portions of the binding wires 48--49, intermediate of the end panels 44--46, (as has been described with reference to the fibre box) then bend the side panels S-S' and end panels 4446 upward to form a box, which has its top open, and thereafter place a hoop 54 around the outside of the assembly to temporarily hold the parts in position to form the box structure as shown in Fig. 1'7, and which is ready to be packed.

After packing, the top panel T is moved down- 55 ward to close the box and the projecting ends of each wire 4|, are first spliced together as indicated at 5656, Fig. 18; then the projecting ends 50-5| of the wires 4848 are crossed diagonally and spliced to their opposite projecting ends 52-53 as indicated at 58-58, the end 5|! being spliced to the end 53, and the end 5| to the end 52.

By this arrangement, the box is easily formed, packed and sealed without resorting to the driving of any nails, staples or the like, and the box so produced is stronger than the ordinary wire bound box, due to its diagonally crossed wire binding.

As in the previously described fibre box structure, this type of box may also be provided with the diagonal wire binding on its lower surface, and in the same manner as described with reference to said fibre box.

Another method of assembling the blanks and a continuous ledge Bil against which the ends of wires to form a box is illustrated in Figs. 3 and 4, in which the end blank is so placed with ref erence to the side walls as to have the binding wires on the end blank extend around the side walls, thereby strongly bracing the sides and ends of the completed box to withstand the strain of packing and handling.

a In certain cleated box structures such as illustrated in Fig. 16, it will be noted that the side panels project beyond the cleats sufliciently to engage the edges of the end panels, so that when the box is completely formed, the end panels are nested in the recesses bound by the projecting walls of the side, top and bottom panels and there nest snugly against the cleats.

Instead of securing the cleats to the body panels as shown in Fig. 16, they may be secured to the end panels as shown at 59, 59 in Fig. 19. The said cleats 59 are preferably spaced slightly inward from the edges of the panels so as to form the body panels will abut, when assembled therewith.

In Fig. 21, a modified end blank structure is shown, in the construction of which is involved the method of forming a diagonal wire binding when more than two binding wires are used.

This end blank comprises two outside wires 62-62, and an intermediate wire 64, all of which are secured to the end panels 6668 by means of staples 1B. The end wires 62-452 are made longer than the intermediate wires 54, to permit them to be drawn together at the center and twisted around the said intermediate wire.

Various changes can be made in the details of construction here shown and described as forming the several embodiments of my invention, any such modifications still being within the scope of the invention here claimed if the principles of construction and results above explained are substantially preserved.

Broadly stated, the main novel features of my invention comprise the following: (1) the stapling or equivalent fastening of certain continuous loops of binding wire to both end panels of a box, as distinguished from prior art structures in which all-binding wires were stapled to the body blank and merely stretched across the end panels; (2) the use of certain continuous loops of binding wire so arranged that each loop extends completely around the box, endwise thereof, and has its free ends twisted or fastened together at one side of the box, as distinguished from box-end holding wires made in two sections, the four free ends of which had to be twisted together, two at each box end.

It is apparent that the arrangement hereinabove described is much simpler and cheaper and more efficient than were those of the prior art having the features also above referred to.
