I lApplication;-fled December 20, 1923, Serial No. 681,709. Renewed November 4, 1926.

This invention relates to a method for assembling the blanks of a fiber shipping case of -a specilied construction. In my Patent i in . on certain conveyor systems. However, the

No. 1,375,127, dated April 19, 1921, and in the Lemon Patent No. 1,428,597 ldated Septemper 12th, 1922, a shipping case is shown in which three blanks are employed, namely,

a body blank folded to provide the bottom, i two side walls and the cover wings, and providedl at the-ends ofthe two side walls and .thebottom with end flaps. The other two blanks comprise each an end wall provided e with, a sealing flap. These sealing fiaps are arranged to be engaged with the cover wings for sealing the case.

A container of this character has great possibilities in its commercial appeal for the reason that it involves a large saving in material, and the bottom and side walls are kept free of all flaps which are objectionable in sliding the box-or 1n carrying the box great practical objection to a box of. this kind at the present time is the cost of assembling the box, as each end has to be separately inserted and stitchedseparately on a wire stitching head. 'lhis involves conjsiderable labor cost land quite large capital investment to dprovide the stitching ma# chines necessary to stitch these containers together. lt is the object ol the present in-l vention to provide a new and novel method ot' handling and stitching these blanks to'- V "ether whereby the fasteners or .stilchesmay be driven iu simultaneously in two rows, thereby substantially cutting the labor cost in two, and considerably lessicniug the capital investment in a large plant where a shipper requires a/number of machines for assembling thc boxes.I I

'In the drawinvs:

Fig. 1 is a plin view of one of the end blanks.- if i Fi r. 2is a plan view of the other end blanll.` e Fig. 3 is a plan view of the body blank showing the tirst step ofthe method, wherein two end blanks are sinulltaneously stitched to the bottom wall of the body blank. Fig-4 shows the position of -the blanks on the anvils. Fig. 5 is a section taken on the line 5-5 'ofF1g. 4. j v,

Eig. 7 a perspective, showing the` third above referred to. However, in m`y prior patent, flaps are provided on the cover wings', but this is immaterial so far as` the Vmethod ot' assembling the blanks that form Lemon, and also shown in my prior patent the container is concerned." The bodyblank 'is scored and cut. to fdrm two cover win s a and b, two side walls c and d, and one e ottom all e. The end flaps l', 9,751', j wud/c are provided on the two endsof the two i side walls and the bottomwall. ,The two end blanks are designated m and 1i and each is provided with a sealing'tlap, one designated o and the other p. The usual way of assembling a boxl of this kind is to fold together the body blank to form a bottom andtwo side walls, insert an end blank andi` then separately stitch down the three end flaps over the endvblank; then the case is reversed and the opposite end blank is put in inexactly the lsame way. lhis requires alto,- gether too much time foizassembly. It is alsotoo large a labor cost. i

I very materially,lessenthe cost of assembly by my new'` method. In the first I step,'the two end blanks m and n arev secured to the bottom wallvof'the body blank on opposite sides byfsimultaneously stitching the flaps g' and j to. these yend walls as shown in Fig. 4 where the stitches are taken in the order designated l, 2, 3, 4, 5. and 6.

" Now conceivably, these stitches or fasteners could be driven in on opposite sides by 'any operator driving the `fasteners in with a hund tool,'one operator being/ stationed on `each side. y commercially practical way of handling the blanks, and to do this workin the quickestk However, this would not be a possible time, a` pair of a'nvils r and sare rovided, which are s aced substantially the ength of the case. ver these anvils will be supprted a pair of stitchin heads such as shown in my prior Patent o. 1,430,150.

The next step is to fold thebox up as shown in Fig. 6fand to present the same to the two anvils whichl are spaced apart sub-l stantially the '.width of the case.` The stitches vbe driven in by a machine.

7, 8, 9, 10, and 1l and 12 are then taken simultaneously on opposite sides. These fasteners could conceivably be driven by two operators on opposite sides of the avils, but obviously for practical purposes they would The case is then reversed and the stitches 13, 14, 15, 16, 17 and 18 taken on the same pair of anvils stitching on opposite sides of the case, being done simultaneously either by two workmen equipped with hand tools or by two stitching heads. y

In factories engaged in large production the end blanks would be rst stitched to the ends of the bottom walls on one machine. The stitched blanks then would be carried to a second machine where the second and third steps would be taken. However, it is possible to perform the three stitches on a single machine by first stitching all the blanks together so that the end blanks adhere to the ends of the bottom wall, then changing the adjustable spacing of the anvils and stitching heads so as to accommodate them to the width of the case; be giventhe second and third stitches to complete the assembly.

lllhat l.' claim is:

l. The method of assembling a shipping case constructed of 'three blanks comprising two end blanks and single body blank the latter including two side walls with an intervening bottoni wall and all three walls having mid ai; their ends, which comprises the simultaneously securing the two end blanks te the flaps at the ends of the bottom wall, second. folding the body blank to bring the side walls in parallelism and simultaneously securing the end flaps of two of the side walls to one end blank. then third, simultaneously securing the remaining two end flaps of the two side walls io the other end blank.-

2. The method of assembling a .shipping case constructed of three blanks comprising two end blanks and a single body blank the latter including two side walls with an intervening bottom wall and all three walls having end flaps at their ends, which comliirises` simultaneously securing the two end blanks to the end flaps of the bottom wall, then folding the body blank to bring the two side walls in parallelism and securing the end llapsof the two side walls to one end blank and then securing the remaining two side tiaps of the two side walls to the other end blank to complete the assembly'.

3. The method of assembling a shipping case constructed of three blanks comprising two end blanks and a single body blank the latter including two side walls with an intervening bottom walt and all three walls having end flaps at their ends, which cointhen the blanks may all blanks to the opposite ends of the bottom' wall, the folding of the body blank to bring 'the side walls in parallelism, and folding over the end 'flaps on the two side walls against an end blank, and over a pair of anvils spaced apart to tit within the width of the case, then simultaneously driving two rows of metallic fasteners through the two flaps into the end blank to secure the same together, and third, reversing the case and placingit over the anvils and securing the remaining end flaps to the other end blank by driving simultaneously two rows of metallic fasteners through the flaps and into the cnd blank. y

4. The method'of assembling a shipping case constructed of three blanks comprising two end blanks and a single body blank-the latter including two side -walls with yan intervening bottom wall and all three walls y having end flaps at theirends, which comprises the laying of the body blank and two end blanks on two anvils spaced substanl tially the length of the case with the end flaps of the bottom wall in engagement with the end blanks and simultaneously stitching the two opposite end flaps of the bottoni wall to the end blanks, and then stitching the remaining flaps to the end blanks to4 complete the assembly. Y

The method of assembling a shipping case constructed of three blanks comprising two end blanks and a single body blank the latter including two side walls willi an inter-A vening bottoni wall and all lthree walls having end flaps at their ends, which comprises the laying of the body blank on two anvils spaced substantially the length of thc case, the placing of the end blanks in contact with the end fiaps of the bottom of the body blank. the simultaneous stitching of such end flaps to the end blanks, secondly, the removal of the blanks and the folding of the same tov bring the side walls into parallclisi'n,

'and the end flaps at one end of the two side walls into contact with one of the end blanks over the two anvils spaced to fit within the -width of the case, then simultaneously stitching such two flaps to the end blank, then reversing the case and bringing the remaining two end flaps in contact with the remaining end blank and simultaneously stitching the same to the end blank.'
