JAMES CARPENTER, OF MORAVIA,A NEW YORK.

BARBED FENCE-STRAP.

SPECIFICATION forming par@ of Letters Patent No. 258,88*?, dafeavaune e, 1882.

l Application tiled February 4, 1882. (No model.)

To all-whom tt may concern Be it known that I, JAMES CARPENTER, of Moravia, in the county of Cayuga, in the State ofNew York, have invented new and useful lmprovements in Barbed Fencestraps, of which -the following, taken'in connection with the accompanying drawings, is a full, clear, and exact description.

The nature of this invention consists in a novel construction of a metallic strap having enlarged or re-enforced edges and transversely crimped or corrugated surfaces and barbs pressed laterally out of said re-enforced edges alternately at opposite sides of the strap and from the convex side of the corrugations, said strap being secured edgewise on the fence and presenting straight or unbroken top and bottom edges. The strap constructed as aforesaid retains its fullwidth throughout itslength. The barbs pressed or st ruck out of the enlarged edges of the strap, and being nearly or quite at right angles to the planethercof, stitl'en the strap, and the projection of the barb from the convex sides of the corrugation renders the same more prominent, and thus requires less length of the barb. lhe corrugatons allow the strap to expand and contract under the variations of the temperature of the Weather, and thus prevent excessive sagging, as well as undue tension of the strap.

Thenveution also consists in a novel method of forming the aforesaid barbed strap, all as hereinafter fully explained.

In the accompanying drawings, Figure l is front view of my improved barbed fence-strap. Fig. 2 is an edge view of the same. Fig. 3 is a transverse section of the strap, showing its form as itissues from the rolls of the rollingmill; and Fig. 4 illustrates the mode of forming the barbs.

Similar letters of reference indicate corresponding parts.

a represents the metallic strap or band,'hav ing enlarged or re-enforced edges, as shown in' Fig. 3 of the drawn gs.

is bent serpentine, as best seen in Fig. 2 of the drawings, so as to present crimped or corrugated surfaces and straight or unbroken top and bottom edges, as illustrated in the drawings.

b b denote the barbs pressed or struck out Ing. 1 of The body of said strap of the 11e-enforced edges of the strap nearly or quite at right angles lfrom the lplane of the strap, and projecting alternately in opposite directions and respectively from the convex side of the corrugations. j

This barbed corrugated strap I construct by first rolling out a band of iron having enlarged or re-enforced edges, as shown in Fig. 3 ofthe drawings,then passing this band between corrugated rollers r r or corrugated dies pressing against opposite sides of the strap, and simultaneously bringing to bear against the two edges of the strap two rollers, s s, as illustrated in Fig. 4 ofthe drawings, the rollers r r producing the corrugations or crimping of the strap, while the rollers s s, in conjunction with the projecting edges ofthe aforesaid rollers, press out of the reenforced edges of the strap the barbs b b. The projecting edges of the rollers r 1' are provided with rabbets c c of proper size to allow portions of the enlarged edges of the strap a to pass between the rollers without distorting or pressing the same. Saidrabbets are arrau ged in such relative positions as to produce by the intervening solid projections of the rllers r 1' thebarbs b b alternately at opposite edges of the strap and outward from the convex portions of the corrugations,thereby makin g them moreprominent and'effective. The described strap a is secured to the fence-post by staples d driven into the post and striding the concave portions of the corrugations thereof', therebypreventing the strap from slipping endwise.

Having described myinvention, what Iclaim as new, and desire to secure by Letters Patent,

l. The strap a, having enlarged or re-enforced edges and transversely crimped or corrugated surfaces, and barbs b b, pressed or struck out ot' said re-enforced edges, substantially as set forth.

2. The strap a, formed with enlarged or re; enforced edges and with'crimped or corrugated surfaces, and the barbs b b, pressed or struck out of said enlarged edges at the convex side of the corrugations and alternately in opposite directions from the plane of the strap, substantially as described and shown.

3. The within-described method of forming barbed fence-straps, consisting in rst rolling out the strap with enlarged orre-enforceded ges, of two attesting Witnesses, at Syracuse, in the then corrugating said band and pressing out county of 0nondaga,in the State of New York, of the enlarged edges thereof barbs standing this 11th day of January, 1882.

in opposite directions from the plane of the JAMES CARPENTER. [L. S.] 5 strap, substantially as described. Witnesses:

In testimony whereof I have hereunto signed C. H. DUELL, my name and afxed my seal, in the presence WM. C. RAYMOND.
