METALLIC STRIP BLANK FOR BARBED FENCING.
No. 272,933. I! Patented Feb. 27, 1883 'NITED STATES PATENT OFFICE.
, THOMAS v. Anus, on NEW YORK, N. Y.
METALLIC-STRIP BLANK FOR BARBED FENCING.
SPECIFICATION forming part of Letters Patent No. 272,933, dated February 27, 1883. Application filed August :23, 1881. Renewed March 8, 1882. Again renewed September 21, 1882. (No model.)
To all whom it may concern:
Be it known that 1, THOMAS V. ALLIS, of the city, county, and State of New York, have invented a new and useful Improvement in Metallic-Strip Blanks for Barbed Fencing, of
as to form projecting barbs.
The improvementconsists of the said ribbed strips, having a groove or crease in the sides of the ribs along the surface of the strips where said ribs join the strips, making the ribs thinner thereat than they are outwardly, to improve the barbs made therefrom both in form and condition, and to facilitate the cutting of the ribs to form the barbs, all as hereinafter described, reference being bad to the accompanying drawings, in which' Figure 1 is a top view of the improved ribbed metallic-strip blank of my invention. Fig. 2 is a side elevation of the same. Fig. 3 isa cross-section of the rod, showing the form to which I reduce it preparatory to making the ribs. Fig. 4 is a cross-section of the strip through one of the ribs when partially formed. Fig. 5 is a cross-section through the rib when the rod is completed. Fig. 6 is partly a side elevation and partly a section of the rolls I employ for the manufacture of the said improved blank-strip. Fig. 7 represents the said rolls in side elevation. Fig. 8 represents a top viewof the barbed strip after the barbs have been formed, and Fig. 9 is a side view of the same when twisted and completed.
The flat strip B, with oval edges, and having short longitudinal ribs A, with pointed ends, along one or more sides, at certain predetermined distances apart, and being creased or grooved, at (J, along theirjunction with the strip B, constitutes the improved blank of my invention, said blank being for the manufacture of barbed fencing by cutting said ribs from the strip at one or both ends along the same toward but not to the middle, and bending them into the form of projecting barbs D, Figs. 8 and 9. I make this blank by drawing or rolling a rod of round or other form into the triangular form represented by the crosssection, Fig. 3, then pass it through the collar and groove-rolls E F, having flat passes except where the recess G is formed in the bottom of the groove, wherein the rod is flattened on one of the angles except where the recess G passes, leaving ribs in the form represented in Fig. 4. From rolls E F, I cause the ribbed strips to pass between the creasingrolls H, having grooves l and creasing-die collars J, which form the creases C. After thus forming the ribbed strip, I cut or shear the ribs from the points along the strip a suitable distance for the length ofthe barbs, and bend them laterally thereto, and finally twist the strip, as represented in Fig. 9, to cause the barbs to point in difl'erent directions. By
' creasing the ribs along the strip, as represented,
the form of the resulting barb is greatly improved, also tlie quality, as compared with barbs made from ribs not so creased, as in Fig. 4, because the crease makes them partially round and less angular on the side out from the strip. The cutis smoother, less cut surface is exposed, and the condition of the barb in respect to its solidity is much better, for where the thickness of the rib is equal at the line of cutting to the rest the tendency to crack, split, splinter, and curl is greater. There is also a material economy in the wear and cost of the mechanism employed for cutting and bcndingthe barbs.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-
The improved ribbed metallic-strip blank for barbed fencing herein described, consisting of the flattened strip B, with ribs A along the surface of the same, creased or grooved in their sides along the strip, substantially as described.
THOMAS V. ALLIS.
