DIE FOR USE. IN MAKING BARBED FENCING.

SPECIFICATION forming part of Letters Patent No. 450,049, dated April 7, 1891. Application filed August 13,1888. Serial No. 282,556. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH H. TEMPLIN, a citizen of theUnited States, and a resident of Reading, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in a Combination of Dies for Use in a Machine for Making Barbed Strips, of which the following is a specification.

This invention consists of contrivances of dies for making barbed fencing by slitting apart plain fiat double blank strips, and at the same time making other cuts in addition to the slitting cuts, whereby two barbed strips are produced, each having two barbs formed on one edge and projecting laterally therefrom in opposite directions alternately with another barb, also formed on the edge but projecting therefrom in the plane of the strip, as follows,- referring to the drawings, in which- Figure 1 represents face views of the slitting and barb-cutting dies and some ofthe bending-dies. Fig. 2 is a diagram of the strip, showing the action of the dies upon it. Fig. 3 is a side elevation of the slitting, cutting, and bending dies, with a blank strip between them. Fig. at represents face views of a modified arrangement of dies. Fig. 5 is a diagram of the strip as out by the dies of Fig. 4.

In the first place I proceed to separate the blank strip A by successive cuts into two strips 1), each having projecting ribs 0, alternating with corresponding notches d, preferably using therefor the dies c f, made with the offset of the cutting-edges h along the middle portion, represented by the line g, parallel to h, and the reversely-inclined diagonals g, joining lines It and g. The length of said'offset is the required length of the projections c for producing three barbs, and the width is that which is designed for the width of thebarbs that are to be made to project laterally from the strip. The length of the parts It together is equal to the length of line g, or may these dies cut the length of one projection and one notch of each strip 1) at each operation, the blank to being fed the length of be somewhat greater, so that.

said dies at each movement. Then I make other cuts or slits 2' partly along the base of the projection c of one strip, partly diagonally across the contiguous projection c of the other strip from its extremity, and partly alongthe base of the latter, the diagonals of the alternate slits i being reverse to each other, and

the extremities of these slits terminating a little short of each other in the base lines of the respective projections 0, thus producing the barbs j, out lengthwise along the strips, but retained thereon by the uncut base-webs Z, left between the extremities of slits i, and barbs It, left between the diagonal cuts of slits i and of the first slits made in separating the blank, which diagonals also serve to point the barbs. To make these slits a, I prefer to employ the dies m 01, substantially like dies 6 f, except being a little shorter and having the gap at 0 in the part g of the offset to leave the uncut webs Z for retaining the barbs j of one barb-strip, and,being so located relatively to said dies 6 f that their diagonal edges g cutinto the projections c from one end, respectively, and suitably to make points 70, and being alittle shorter than dies 6 f, and also shorter than the length of the feed move.- ments of the strip, they leave the other webs Z between the cuts of the successive feed movements and uniting-barbs j to the other barb-strip; but these dies may be constructed in two separate pairs, each being the length of a slit 1', as shown in Fig. 4. Following these dies, which complete the cutting of the barbs, are two pairs of bending-dies p g, which bend the barbs j, one pair to each barbed strip, and each pair bending two barbs at the same time, but in opposite directions. They are likewise arranged in the due relation to the preceding dies for working successively with them.

I have represented the parting of the blank by the dies cf as the first step in the process,

because it is the preferable way; but it is obvious that the slits t' may be first made and the parting next, if preferred, as represented in Figs. 4; and 5, and I consider both ways included in my invention.

I reserve the method herein for a separate application.

gap 0 and being located with relation to dies ef for cutting along the base-lines of the projections formed by dies e f and across the 15 same at one end, also the bending-dies p q, substantially as described.

Signed at New York city, in the county and State of New York, this 2d day of May, A.D. 1888.
