JOHN G. MILLIGAN, OF BROOKLYN, ASSIGNOR TO THE LALANOE & GROS- JEAN MANUFACTURING COMPANY, OF NEW YORK, N. Y.

FENCE-STRAND OF SCRAFZ METAL.

SPECIFICATION forming part of Letters Patent No. 268,264, dated November 28, 1882.

Application filed July 26, 1882. (No model.)

To all whom it may concern: I

Be it known that I, JOHN G. MILLIGAN, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented a new and useful Improvement in Fence-Strands of Scrap Metal, of which the following is a specification.

The object of my invention is to utilize the waste scraps resulting from cutting or stamping spoon-blanks from rectangular sheets of metal, as is common in the arts. Such scraps have heretofore been a source of expense and annoyance to manufacturers, there being no profitable known way of getting rid of them. I attain this object by cutting the waste scraps into symmetrical sections and forming them into a chain.

The subject-matter claimed is hereinafter specifically designated.

In the accompanying drawings, Figure 1 shows a portion of a sheet of metal as it appears after cutting out the spoon-blank. Figs. 2, 3, 4, and 6 show various forms of chain made by interlocking the sections out therefrom. Fig. 5 is a transverse section of the cable shown in Fig. 4 in one stage of its formation.

The cutting of the spoon-blanks B from the sheet A leaves a skeleton of the form shown in Fig. 1, which may be considered as composed of symmetrical sections a b c of difiering shapes, on being triangular in shape, 12

three-pronged, and c bar-shaped. These sections are severed from each other by transverse cuts at the points indicated by dotted lines in Fig.1. Before or after severing, a

slot, d, is formed in each triangular section.

This may be conveniently done when cutting out the spoon-blanks. The adjacent ends of the bars 0 are inserted in this slot and clinched in well-known ways, as shown in the drawings, thus forming a barbed chain capable of use for fencing or for other purposes.

The three-pronged sections 11 may be perforated and strung on wires for fencing in wellknown ways.

In Fig. 2 I have represented the alternate triangular sections a as projecting in opposite directions, and the consecutive narrow strips 0 as thrust through the apertures d from opposite sides; but boththese methods, it is evident, may be varied.

In Fig. 3 I have shown a method of linking the separate parts by causing the triangular pieces a to project all in the same direction, and with the ends of the strips 0 at each section a folded upon the same side, but with the successive links alternating as regards that side. 1

Fig. 6 shows still another modification differing from that shown in Fig. 3, in that the alternate strips care reversed to cause the adjacent curved ends thereof to project in the same direction, either-downward or upward.

In Figs. 4, 5, and 6 I have shown a method of clasping the ends or corners of the triangular sections or upon the folded ends of the strips 0 to afford additional strength to the joint or link. This consists in bending the bythe dotted linef uponthesideof thelinked chain opposite the ends 0, and in wrapping the pointed projection to in the opposite direction and bringing its extremity across the bent portions of the ends 0, as shown in Figs. 4 and 5. The extremities of the strips 0 may then be folded across the end a, and likewise the corners a of the triangular sections 01 may be bent over that portion of the projection. a which crosses the central portion of the strai gh t side of the section; or the angular points a and 0 may be allowed to project outward from the body of the chain at any required angle,

as shown in Fig. 5, and thus serve as barbs in the manner of the ordinary barbed wire for fencing.

The method of folding the triangular sections may be varied as found desirable, and only thefirst-mentioned 'fold may be employed, as illustrated in Fig. 6.

I do not broadly claim herein forming cables of sheet-metal scraps, as that constitutes the subject-matter of another application filed simultaneously herewith.

I claim as my invention 1. The combination, substantially as hereinbefore set forth, of a series of scraps formed by cutting spoon-blanks from metal sheets, In testiinony whereof I have hereunt) subunited with each other by interlocking the scribed my name this 24th day of July, A. D. 10

same so as to form a continuous chain. 1.882.

2. The combination of the narrow metal strips and the triangular sections, interlocked JOHN MILLIGAN' with each other alternately, forming a chain Witnesses: with or Without barbs, substantially as here- JAMES OOOHRAN,

inbefore set forth. THEODORE A. PERHAM.
