speeication of Letters Patent.

Application le April 6, 1909. Serial No. 488,300.

To all whom it may concern:

Be it known that I, JOHN N. HAHN, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Staples, of which the following is a specification.

My invention relates to improvements in staples, all substantially as shown and described and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of my new and improved staple. Fig. 2 is a plan view thereof, and Fig. 3 is an end view. Fig.4 is a side elevation and Fig. 5 is a cross section thereof. Fig. 6 is an enlarged-sectional elevation of the staple centrally lengthwise through the prongs and shown inserted in a double fold or layer of stock which the staple is adapted to lock together as hereinafter fully described.

As thus shown the staple is formed up in suitable dies from a sheet or strip of suitable sheet metal, such as a heavy grade ofl fixed together by some means or other for i handling and shipping. The said flaps being folded inward from the sides one upon the other, they are secured by two or more t staples fixed in each bottom. Thus, in Fig. y 6' the stock shown represents a portion of a 1 paste-board box bottom in which the Hap i 2 is inside the box and liaps 3 outside thereof, and staple S is inserted from the outside g across the meeting line of the outer flaps and through the corresponding inner flap. The other staple in the bottom would engage through the other inner flap not shown but like the one shown, and then by bending and clenching the ends of the prongs 4 fiat against the inside of the bottom thel work is done so far as the staples are concerned. However, as to this matter of securin the flaps, it should vbe known that heretofore the practice has been to simply paste or cement the flaps together and there was no other fastening means. But paste alone put of which these boxes are manufactured 1s stiff or rigid like a wooden board, and when moistened for pasting is liable to war or curl and to thus render the paste me ective. Hence the necessity of means for locking the stock or flaps together other than the paste alone, and which according to my-invention supplements the paste or cement. That is, I employ the paste as formerly, which helps to make a sealed bottom for finely divided or pulverized goods and prevents creeping or leaking between folds, and apply the staples in addition after pasting and folding the flaps. This not only locks the flaps firmly together but prevents their separating as they do otherwise while the paste is setting. The staples therefore serve at least a two-fold purpose and contribute to make a parcel which will sustain the weight of the contents without any danger whatever that the bottom will give way when the parcel is handled.

.Now, as to the construction of the staple itself, it will be seen that it is original in several particulars. Thus, the back has a relatively deep raised rib 5 lengthwise thereof but terminating in this instance short of the base of said prongs and which are shown as having each a rib or bead 6 on the inside and starting with the greatest depthin the body of the staple at the ends of bead or rib 5 and within the ends of said body. This throws a distinct depression 8 in the outside of the staple at the junction of the prong and. body and which runs down on the outside of the prong in a taper approxi` Q ribs 6 in said prongs is determined by the thickness of the stock to be secured whether it be relatively'greater or less thanherein shown. v

In view of the foregoing it will be seen resented Mae. s, 1ero.

that my improved staple is especially adapted to fasten paste-board, especially corrugated board, without breaking down or tearl ing the paper lining or body laterally therehas been found insufhcient because the stock l of, because the flat ends l of the prongs are lari 951,393

easily bent Without bowing, kinking or bend# `ing that portion of the prongs `which lies Within the body of the stock.

What I claim is:

1. A staple formed up from sheet metal and having a rib located centrally lengthwise outside on its back and prongs with ribs on their inside starting in the ends of the said ribon the back of the staple and terminating in a taper substantially at the middle of the prongs.

2. A staple having a raised rib in its back terminating within the ends of the back and provided with prongs having tapered ribs on their inside starting with their greatest depth at the base of said rib on the back and tapered thence. to about the middle of the prongs lengthwise, the portions of said prongs below said ribs being Hat and adapted to be bent to clenching position.

3. A staple having a remorcing rib ontside on its back and prongs having ribs inside gradually reducedfin cross section from end to end and extending from the ends of said rib in the back of the staple to approxmately the middle of said prongs and said back having straight flat sides parallel to the rib therein.

. In-testimony whereof I ahx my signature 1n presence of two Witnesses.
