WILLIAM 'IIS CH, OF MILWAUKEE, WISCONSIN.
T 0 ZZ whom it may concern:
Be it known that I, WILLIAM 'Tlsorr, a citizen of the United States, and resident of ilwaulree, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Box- Corner Constructions; and I do hereby declare that the following is a full, clear, and exact description thereof.
My invention relates to new and useful improvements in means for connecting together the sections of a box, particularly of that relatively light type formed of fiber board or similar material.
it is in general the object of my invention to 1310'11116 an economy of material and operative steps in the manufacture of boxes of this character, and to increase the durability and neatness of appearance of such boxes.
It is more particularly my object to provide a metallic angle plate or strip for connecting sections of a box, which permit the sections to be accurately positioned \if'ith respect to each other in a most convenient manner.
A sti l further object resides in a connecting strip for the sections of the which does not interfere with the application of pasted binding strips or coverings to the corner portions the outer surfaces of the strips.
Wit-h the above and other objects and advantages in view, which will be apparent the \flescript-ion roceeds, my invention resides in the novel feat of construction, combinat wil' be hereinafter more particularly de .ibed and defined by the appended claims.
in the'aceom ninying d nvings:
Figure 1 is a PQTSPBCUYG view of corner portion of a box constructed in accordance with my invention, loo-hing toward the outside of the box.
Fig. 2 is a'similar view looking toward the inner side of the box.
Fig. 8 is a sectional view through the corner portion of thebox on a planeindicated by the line.33 of Fig. 2.
Fig. 4 is a perspective view similar to Fig. 1, and showing a slightly modified structure.
Fig. 5 is a plan view of a stock sheet of metal from which my improved connecting strips are cut, and showing the arrangement for cutting the strips without any wastage of material.
Specification of Letters Patent.
H1 and arran ement of parts which Patented Jui 5, 1921.
Application filed August 18, 1919. Serial No. 318,163.
Referring now more particularly to the accompanying drawings, 5 and 6 designate respectively wall sections of a box for containing cigars or other articles, these wall sections being formed of pressed fiber in the present instance, although they may be formed of any suitable material.
My improved means for connecting these sections together comprises an angular strip 7 formed of very light sheet metal and fitting against the edge portions of the inner faces of the box sections, securing tongues 8 extending outwardly from the side edges of the strip and being passed through the box section and then bent toward the corner of the box, the body plate 7 and tongues being pressed into the box sections so as to lie flush with the surfaces thereof.
Fig. alwhich illustrates a perspective view of a box corner shows a modified form of my invention, wherein the securing tongues 8 are split transversely at their outer ends, and the divided sections in this instance are folded back upon the box body in opposite directions, the said folded ends being em.- bedded in the material to form a flush face.
An exceedingly simple, durable, and efiicient connection is thus provided, which greatly facilitates the operation of setting up and forming the box. By placing the angular strap at the inside of the box corner, considerably less expenditure of metal is necessary than ifthe strao were placed on the outside of the box. it the same time, the corner edge of the box presents a fiber or similar surface which will coact with the paste of the usual binder strips or covering applied to the outer surface of the box, whereas if a metal surface were afforded at the corner of the box, the covering would strip off by failure of its paste to efi'ect proper engagement.
It will further be not-ed that by placing the angle strip at the inside of the box, the strip is braced by its engagement with the box sections against spreading movement due to outward or bulging pressure against the box sections, and also, the strip may be more readily pressed into the material of the box sections. In assembling the box, the strip is first accurately associated with one of the sections, the other section is then moved up against the first section in accurate relation and the tongues are clenched through said other section, and any unevenness in the edges of the sections may be corrected by trimming oil the uneven edge after the sections have been connected, Which of course couldnot be effected were the stri on the outside and any unevenness would t en result in distortion of the completed box. It will be further noted that by clenching the tongues inwardly, the edges of the sections are fairly protected,
and also the spaces between these tongues.
serve to distribute bending 'or breaking stresses Which would occur upon. outward bulging pressures against the sectlons, to
7 thus relieve the liability of bending or breaking the sections at the edge line of the connecting strip;
What is claimed is:
1. In a boxstructure, a pair of box sections disposed in angular relation, an elongated connecting strip longitudinally bent to provide an angular cross section and env gaged against the edge portions of the inner faces of the box sections, and tongues'extending fron'r the edge portions of said strip through thebox sections, said tongues having their outer portions bent to lie against the-outer faces of the box sections.
2. In a box structure, a pair of box sec- 7 tions disposed in angular relation, an elongated connecting strip longitudinally bent to provide an angular cross section and engaged agalnst the edge portions or the inner faces of the box sections, and tongues 'ex' WILLI M TISCH.
