CHARLES S. BIRD, 0F EAST WALPOLE, MASSACHUSETTS.

PAPER BOX.

Specification of Letters Patent.

Patented Nov. 23, 1909.

Original application filed May 13, 1909, Serial No. 495,668. Divided and this application filed J' une 4, 1909. Serial No. 500,116.

T o all whom tt may concern:

Be it known that I, CHARLES S. BIRD, a citizen of the United States, and a resident of East Walpole, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Paper Boxes, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure l and Fig. 2 are plan views of pieces of straw-board, card-board, or the like, out of which myimproved box is constructed; Fig. 3 is a plan view, slightly on the perspective, showing the two parts illustrated in Figs. l and 2, united together and in a flat or knock-down position; Fig. 4 is a perspective View of the parts shown in Fig. 3, set up in rectangular form; Figs. 5 and 6 are perspective views of the box with the parts assembled in nal position for use and havin the longitudinal binding strip or strips afhxed thereto, Fig. 5 showing the box with the four transverse strips along the corner edges of the box, together with a single longitudinal strip encircling the box, while Fig. 6 shows the four transverse strips, together with two longitudinal strips.

Similar letters refer to similar parts throughout the several views.

The resent application is a division of my apliiication filed May 13th 1909, Serial Number 495,668, this application embracing certain modifications and alternative forms of construction of the inventions shown and claimed in my prior application.

In the construction of folding paper boxes of substantially rectangular form, it has been my experience that the parts assembled together which go to make up the box should preferably have a certain strutting action, that is to say the parts should mutually combine each with the other in order to afford the requisite strength and rigidity to the box, where such boxes are composed, as in my improved box herein described, of material that is easily cracked or broken. It is also necessary and essential that the various lparts should be so combined as to be capable of being packed and shipped in a fiat or knock down condition so as to economize' freight charges, and, at the same time, be capable of being set up in final position in a simple and efficient manner when such boxes are to be used by the consumer. It is also of commercial advantage, when large among other things, is to accomplish these desired advantages in the construction of folding paper boxes, and to this end I take two pieces of rectangular strawboard, or cardboard, such as are shown in Figs. 1 and 2, and cut and score same, as illustrated in the ligures, the heavy double lines being the cuts, and the light triple lines being the scored parts. I may also combine the two pieces of rectangular strawboard or cardboard, such as are shown in Figs. l and 2, into a single elongated piece, which shall constitute in itself the rectangular form of box shown in Fig. 4.

Referring to Figs. 1 and 2, A and A' constitute the side pieces of my box, provided on either side with extension flaps E, G, E', G', respectively, which extension flaps are integral with their respective sides. At one end of A and A respectively are the end pieces B, B', integral with'A and A respectively, and having integral with themselves the extension flaps C and D, and C and D respectively. At the opposite end of A and A are the binding flaps F, F', respectively, which, when the box is assembled in position, are bent inwardly and are fastened or secured by eyelets, rivets, or by any other means, such as adhesive, the flap F being, when the box is assembled in position, afixed to the end of the end piece B', while the flap F is aiiixed to the end of the end piece B, as isclearly illustrated in Fig. 4.

It will be observed that the flaps C, D, E, G, C', D', E', G', are each of substantially Vthe same length as their contiguous end or side pieces respectively, A, B, A', B', and the combined width of the fiaps E, G, and E', G', is substantially the same as the width of the sides A and A' respectively.

Having now described the various parts of my improved box, they are now assembled by having the flap F bent substantially at right angles and inwardly and afxed or paper or cloth I, I, I2, I3, shown in Figs. 5

otherwise secured to the inner surface of the 1i end piece B, while the iap F is bent substantially at right angles and inwardly and .1 affixed or otherwise secured to the inner surg i face of the end piece B, as is shown in Fig. 4, where the parts are more clearly shown l than in Fig. 3, F ig. 3 representing my img proved box when the same is in a flat or knock down condition ready for ship-l ment. In assembling the various parts of my box 5 in final position, the extension flaps G, C, L D, D', are bent inwardly and at substantially right angles with the end pieces B, B', whereby they furnish a strutting support i to the sides A, A. Then the extension liaps of the sides E, E', G, G, are bent inwardly l, at substantially right angles with the sides A, A, and inasmuch as their combined i width is that of the length of the end pieces l B, B, their exterior edges will close against l each other, so as to form a furt-her strength ening, strutting support for the sides. l In case such extension flaps should not meet and close against each other, or should E overlap, the strutting action would be 5 largely, if not wholly, lost, but such con: struction would still be within the scope of i my invention. However it is obvious that increased strength and rigidity are attained by employing the strutting action hereinbefore described. I then take strips of strong and 6, and paste or otherwise secure same to the corner edges of the box, thereby holding together the extension iiaps E, E', and G, G', which form the top and bottom of my box.

Vhen it is desired to form a box such as is shown in Fig. 5, I paste or otherwise secure a single strip of strong paper or cloth, shown in F ig. 5 by H2, which shall encircle the entire box longitudinally, thus closing and holding securely in position the extension iiaps E, E, and G, G.

An alternative form of construction is such as is shown in Fig. 6, where I use two longitudinal binding strips H, H, in combination with the transverse binding strips, which alone were the subject matter of my invention, now claimed in my pending application, Serial No. 434,872, filed May 25th 1908. These transverse strips, together with the longitudinal strip or strips, afford a convenient and secure method of holding the extension liaps of the sides in position, and, at the same time, when it is desired to open the box, they can be readily cut or torn away.

What I claim as new and desire to secure by Letters Patent is the following, viz:-

1. A rectangular folding paper box, comprising end and side pieces having extension flaps having their combined width substantially the same as the width of said side and end pieces, turned in extension flaps integral with the sides and bent in and secured to the adjacent end pieces, transverse binding strips secured to the corner edges of the box, and binding means extending longitudinally about the box, all of said strips being adapted to hold the extension flaps of lthe sides in position so as to form the top and bottom of the box, substantially as described.
