. stapling Machines: 00., a co ',:.ware 1 'I'hi's: invention relates to boxes and particu larly to wirebound fiberboard boxes. 1 f 7 Among'other objects, -the inventionis intended to provide a strong and dependable wirebound fiberboard box; to provide a wirebound fiberboard box that is light in weight and economical to manufacture; to provide a -wirebound fiberboard box that is flexible and elastic; to provide asectional wirebound fiberboard box that' h' as tight corners; to provide a wireboun'd fiberboard box soconstructed andrarrang'edas 'toincre'ase the resistance of the fiberboard-to stresses and strains at the points where it is subjected to the,

overlapping the edges of adjacentsections of fiberboard. 'Such an overlapping provides a double .thicknessxof fiberboard along. box corners, preserves the sectional characteristics of the box which permits one section to shift relative to an adjacent section, and at the same time pro vides'a tightlcorner.

.One illustrativefembodiment of the invention is shown in the'accompanying drawing in which:

greatest stresses and strains; and generally to I provide a balanced wireboundifiberboardi box strongpenoiigh at all pointst'o carry its load and not excessively strong at any point. j

Aszconducive to a bettersunderstanding' of this invention, it should be notedthat in prior. wirebound'fiberboard box constructions .s'uch asthat shown inzUnited States Patent Number 1,334,271, dated March 16,1920, encircling binders and a sheet of fiberboard side material bent integrally over the box corners were stapled to endcleat frames. In such construction, the fiberboard extending integrally over the box corners resisted initial relative longitudinal shifting of adjacent box sides under stresses and strains, but continued or increased stresses and strains caused the fiberboard at box corners to shear or tear along the corner lines. Also, the single thickness of fiberboard at the box corners frequently failed to resist biting in of the tensioned wire bindingsand destructive blows to which a box corner is subjected in rough handling. The present invention is intended to remove the foregoing deficiencies in the box of said patent by providing a sectional wirebound fiberboard box reenforced at box corners and adapted t flex under stresses and strains without shearing or tearing the fiberboard.

I am aware of another sectional wirebound fiberboard box in which the corner edges of the sections are reenforced by turning the fiberboard edges under to provide a double, thickness of fiberboard along the corner edges of the box. This construction is an improvement over the box shown in said Patent Number 1,334,271 in that it provides the necessary reenforcement at the corner edges of the box and permits one section of the box to shift relative to an adjacent section to avoid shearing or tearingof the fiber board at box corners, but leaves an opening along the corner edges of the box. The present invention is intended to remove this deficiency by .;Figu're. .1 is a perspective view of a box embodyiri-g-the invention, with the lid or cover sectionpartly raised; 3

: gfl'heillustrative-fiberboard box shown in Fig. '1

comprises four separate side sections and two end sections. Each side section comprises a sheet of fiberboard I, preferably corrugated fiberboard,

and end cleats-2. Each sheet of fiberboard l extends beyond each cleat end asufficient distance J to overlap the adjacent sheet of fiberboard at box corners, as best shown in Fig. 3. The end cleats 2 of the several sections form, a cleat frame at each end of the box. The four side sections are connected together in foldable relationship by flexible binders 3, preferably wires. The outside binders 3, which overlie the cleats 2, are secured to the fiberboard sheets I and cleats 2 by staples 4 which straddle the binder, pass through the fiberboard sheet, and anchor in the cleat. The intermediate binders 3 are secured to the fiberboard sheets by staples 4 which pass through the side sheet and are clinched in the under surface "of the side sheet.

The ends of the binders 3 preferably terminate in loops 5, which may be hooked together at the closing corner edge of the box to close the box,

as shown in Fig. 2.

The end sections are similar to those shown and described in United States Patent Number 2,190,199 of February 13, 1940, and are attached to the box in the manner described in said patent and as shown in Figs. 1 and 2.

The box may be made on a well-known stapling machine, whichstaples the binders 3 to the side sheets I and cleats 2 to produce a flat box blank of the character shown in Fig. 4. The end sections are prepared on a similar stapling machine attachment to each other, they can shift relative to each other under stresses and strains without tearing of the side sheets.

The term fiberboard will be understood asl including other material 0'! a simrlahchairactrsuitable for box siding, whichtends to crumple or" crush rather than break under distorting pres,- sures.

It will be understood that the invention is not to be limited to the specific embodimentsh'own hereinior illustration.
