UNITED STATES PATENTx OFFICE- THOMAS V. ALLIS, OF NEW YORK, N. Y.

BARBED METALLICv FENCING.

SPECIFICATION forming part of Letters Patent No. 244,726, dated July`26, 1881.

' i Application filed January 24, i880. v

To all whom it may concern:

Be it known that I, THOMAS V. ALLIs, a citizen ot the United States, residing at New York, in the county and State ot' New'York, have invented a new and useful Improvement in Barbed Metallic Fencing, of which the following is a specification.

This invention consists in the combination, with a rod having barbs on one'side only and a narrow web along the sameside between the barbs, of a tin on the opposite side of the core which shall be of the proper size to counteractl the unequal effect of the barbs and webs between them on the rod while twisting. Were this tin omitted, the rod would assume a spiral or cork-screw shape in consequence oif a preponderance of metal on one side, which is objectionable. I propose to add enough metal in this tin tothe opposite side of the rib or core to balance the barbs and webs between them, so that the rod will be straight when twisted.

The narrow webs between the barbs serve several purposes: rst, in the formation of the barbs by stamping or punching them from the wide iin the strength of the core is not impaired, as it wouldl be if the cuts were made into or close to it; second, greater surface is presented to view; third, it has a tendency to make the rod elastic 5 fourth, it permits broader cutting-surfaces to the dies, which makes them more durable.

The size of the barbs and webs between them maybe varied to suit the wants and ideas of different localities and countries. Conse- .quently the balancing-tin must be correspondingly varied in dimensions. Therefore I do not confine myself to any special size of iin on the core opposite the barbs.

It is obvious, where there is a row of barbs 4o on each side of a rib or core with webs between them, that one balances the other, and this invention applies only to barbed fence-rods having` a row of barbs on one side.

Figure I is a side view of a rod having a broad iin on one side, from which to form thev barbs, and a narrower one on the opposite side, intended for balancing. Fig. 2 is a side view of the same having barbs formed on it, and Fig. 3 is a side view of the finished rod with the barbs .cutand said rod being twisted.'

A represents the core or body; B, the wide fins out of which the barbs D are formed, and O a plain rib or balancing-'tin to balance barbs D, and webs B remaining between the barbs D when the surplus metal is cut away.

This invention differs from all others in metallic barbed fencing, in that it consists of the application of a plain unbarbed balancing-tin to a rod having one row of barbs along one side only, between thebases of which barbs there is left'a narrow .web of the iin, out ot' which the barbs are formed, said plain n'being opposite to the barbs and their connectingwebs, and being equal in capacity to said connecting-webs for counteractin g their tendency to make the rod twist. crookedly when not so balanced.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is v A barbed metallic fence-rod having a single row of barbs with narrow ribs B between them, andaplainrib,O,ot'samedimensionsinbreadth and thickness as said ribs B', on the opposite side of the core thereto, substantially as specied.
