STAPLE-STRI-P BLANK.

SPECIFICATION forming part of Letters Patent No. 358,985, dated March 8, 1887.

Application tiled November l, 1886. Serial No. 217,663. `(No model.)

To @ZZ whom, may concern;

Be it known that I, FREEBORN F. RAY- MOND, 2d, ofNewton, in the county ofMiddlesex and State ot' Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Strips for Forming Staples or Two-Pronged Fastenings, of which the following is full, clear, and exact description, reference being had tothe accompanying drawings. forming a part ot this specification, in explaining its nature.

The object of the invention is to provide a strip or blank from which two-prong fasten ings or strips may be cut, which shall have eccentric points and long bevels formed upon the same side of each shank or prong ot' the staple or fastening.

In the drawings, Figurel is a View in elevation ofthe blank strip. Fig. 2 is a vertical section upon the dotted line of Fig. l. Fig. 3 is a view in perspective otthc complete staple or two-prong fastening. Fig. et is a view in side and end elevation of a plate from which the strip is formed. Fig. 5 is a View in side and end elevation ot" a plate of somewhat different shape from that shown in Fig. 4. Fig. 6 is a view in section illustrating a staple formed from said strip. t

The blank strip is cut from a plate of metal of uniform thickness throughout, (see Fig. 4,) or from a plate having the inclined or tapering surface, as represented in Fig. 5, and so as to form a series of shanks or prongs, a, connected at their upper ends by an uncut section` a', ofthe plate.

Vhen the plate is formed as represented in Fig. 5, it will provide the lowerendsof the shank with the eccentric points and long bevels a3. W'hen the plate used in Fig. 4 is employed, the blank strips are submitted to a further forming operation, whereby the lower ends ofthe shanks are ilattencd sufticiently to forni the long bevel a and the eccentric point a2. rPhe staple or two prong fasteningis completed by separating the strip upon the lines b. The object in thus shaping the Shanks or prongs is to provide astaple or fastening that shall in driving be compelled, because of the shape ofits point, to take an inclined course rather than a straight course.

Having thus fully described my invention, I claim and desire to secure by Letters Patent of the United States--- A staple or two-prong-tstcning strip blank comprising a continuons head or section having a series of depending shanks or prongs, a, having the long beveled or inclined surfaces ce, andthe eccentric points ai, substantially as described.
