DIE FOR USE IN MAKING BARBED FENClNG.

SPECIFICATION forming part of Letters Patent No. 450,047, dated April '7. 1891.

Application filed August 13,1888. Serial No. 282,554. (No model.)

I Dies for Use in Machinery for MakingBarbed Strips, of which the following is a specification.

This invention is an improved contrivance of dies for producing two barbed strips from one double blank strip by first punching pointed barbs at intervals along the middle of the double blank strip having retaining connection at the base with the strip, bending said points into suitable lateral projection, and separating the uncut webs between the barbs, so as to divide the barbs so made alike between the two strips thus produced out of the blank.

Referring to the drawings, Figure 1 represents face views of one arrangement of dies that may be employed to carry out my invention. Fig. 2 is a diagram of the blank strip, showing the action of the dies on it. Fig. 3 represents face views of other or modified forms of dies that may be employed. Fig. 4 is a (lllgllfilll of the strip, showing the action of the dies of Fig. 3; and Fig. 5 is a side elevation of dies, such as represented in Fig. 3, with the blank strip between them.

In the method of operation I punch pointed barbs c at intervals along the middle portion of the blank strip a, which is a plain flatstrip of metal of suitable width for two completed barb-strips Z), so that they have retaining connection at their base with the strip by intervening uncut webs (I left between each two barbs, and, also, so that the punching of the barbs separates the rest of the blank between said webs into two parts, the points of said each two barbs being cut from close proximity in the blank; but the bases are distant from the next two the length of an uncut web cl, and the edges of the barbs are preferably parallel, except at the points. After thus cutting the barbs Ibend them laterally to the strip for the required project-ion therefrom by any approved benders, as cf, and then separate the remaining uncut webs d by cutters, as g 71, alternately in the lines of the different edges of the barbs, so that the making of two strips is completed and the barbs are equally divided between them, two together, alternately on each strip, and the barbs of each couple are bent in opposite directions.

To cut the barbs I prefer to employ suitable punches 1' withcorresponding counterparts j, adapted to cut parallel edged and center-pointed barbs, as shown in due succession, preferring to employ four in a gate for cutting four barbs at each operation, which punches may either be arranged in the order of Fig. 1 or of Fig. 3, as preferred, the former being a contrivance of two punches cutting points together at the middle of the gate with one, each side cutting points reversely, and l the latter being duplicate contrivances of two punches cutting pointstogether and arranged side by side in the gate. Thus four barbs are made, two on each barb-strip at each operation of the dies, and two are bent in one direction by one pair of the bending-dies and two in the opposite direction.

The method of operation herein described is reserved for a separate application for a patent.

What I claim, and desire to secure by Letters Patent, is- I l. The combination of dies for producing two barbed strips from one double blank strip, which consists of punching-dies '6 j, adapted for punching at intervals along the strip pointed barbs, as 0, having retaining connection of the base with the strip, and web cutting dies, as g 72, adapted for separating the uncut webs between the barbs along the lines of the respective edges of the barbs alternately, substantially as described.

2. The combination of dies for producing two barbed strips from one double blank strip and bending the barbs laterally to the strips, which consists of punching-dies ij, adapted forpunching atintervals along the strip pointed barbs, as 0, having retaining connection of the base with the strip, web
