DIE FOR USE IN MAKING BARBED FENCING.

SPECIFICATION forming part of Letters Patent No. 450,044, dated April 7, 1891.

Application filed July 30, 1888. Serial No. 281,397. (No model.) i

Pennsylvania, have invented certain new and useful Improvements in a Combination of Dies for Use in aMachine for Making Barbed Strips, of which the following is a specification.

This invention consists of improved con-' trivances of dies for producing two barbed strips from a double blank strip by making slits at intervals along the strip in two parallel lines and diagonal lines connecting the parallel lines and making other slits in line with and opposite to the parallel lines of the first slits across the diagonal lines by which the blank strip is separated in two parts, and pointed barbs are cut on the edge of each part thus separated.

The invention also comprises the combination of bending-dies with the improved slitting-dies for bending the barbs for the required lateral projection, as follows, referring to the drawings, in which Figure 1 represents face views of slittingdies of my improved contrivance, together with other slitting-dies and bending-dies used therewith. Fig. 2 represents a diagram of the blank strip, showing the effect of the dies on it; and Fig. 3 is a side elevation of the slitting and bending dies with a blank strip between them.

I make a pair of slitting-dies a b, having cutting-edges at c d to make the slits e f in the blank strip a, also cutting-edges at g to make the slit h, and also cutting-edges atz' to make the slit j, all in the one pair with suitable grooves or recesses Z in the sides and concavitiesm in the faces of the dies bet-ween the respective edges to enable the slits to be made in the relative arrangement shown without cutting or breaking the metal through from one slit to another, the slits c and f being located one in advance of the other to leave an uncut base-web 70 for retaining two barbs 0 on the barb-strip p, and each being made partly in two different lines parallel to each other and distant apart the width of the barbs to be made and partly in an oblique line connecting the said parallel lines with the oblique lines of the two slits in reverse of each other as to their inclination and distant from each other the length of two barbs and their connecting-webs, the slit h beingin line with one of the parallel lines of slits e f and opposite the uncut web 7: in the other of said lines, and the slitj being in line with said uncut web 7t and in advance of slitf and oppo site the interval of uncut web a left between slit f and the preceding slit 6 for the retaining base-web of two other barbs on barb-strip q. The webs n are left uncut through the feeding of the blank strip a the length of said webs more than the length between the extremities of slits e and f at each movement of the blank. It is immaterial whether edges t be located in advance of edges d or in relatively the same position in rear of edges 0. The effect will be the same, and I include such arrangement in my claims. By the terms advance and rear I mean relatively to the direction in which the strip feeds, and it is also immaterial whether the edges 0, d, g, and t' are all formed on two parts or dies, as a b, or whether separate parts or dies are employed for each. Iprefer, however, to arrange them as represented in the drawings; but I consider the separate arrangement included in the claims; and with these dies so constructed I provide two pairs of parallel-edged slitting-dies s t to cut the slits a successively to the cutting of the others above described,

which slits a extend from the diagonal lines to the slits h and j, respectively, on the lines of the parallel portions of slits e and f, and complete the cutting of the barbs and the separating of the blank into two barbed strips, these dies being suitably located in range with dies a Z) for successive operation therewith, and next following them I provide two pairs of bending-dies w as for bending the barbs laterally to the strip and alternately in opposite directions. Said dies being in suitable punchand-mat-rix contrivance. for the purpose, a suitable guideway will be employed .for conducting the strip along the dies properly. The dies s and 25 also prolong or extend the parallel portions of slits cf, as required, for the length of the barbs and of the retainingwebs 7c and it.

What I claim, and desire to secure by Letters Patent, is-

1. The improved dies for making barbed metallic fencing by producing two barbed strips from a double blank, consisting of the pair of slitting-dies a b, havingcutting-edges c (I located one in advance of the other and each partly in two parallel lines, as h n, and partly in a diagonal line, as fe, connecting the parallel lines, said diagonals being inclined reversely to each other, also having cutting-edges g opposite to the interval between edges ed, an d also having cutting-edges 2 in extension of either extremity of edges 0 (Z and in the opposite parallel lines thereto, as described.

2. The combination, with dies a I), having cutting-edges c (I and g 1', adapted for producing slits c f and 71. j, of two pairs of slittingdies 5 t, adapted for making slits it together therewith and producing two barbed strips from one blank, substantially as described.

3. The combination, with dies at I), having cutting-edges e (Z and g i, with intervening grooves in the sides and concavities in the faces adapted for producing slits cf and hj, of the pairs of slitting-dies st, adapted for making slits 20 together therewith and producing two barbed strips from one blank,
