BARBED METALLIC FENCING.
SPECIFICATION forming part of Letters Patent No. 466,748, dated January 5, 1892.
Application filed June 10, 1889. Renewed April 24, 1891. $eria1 No. 390,245. (No model.)
To all whom it may concern-.-
Be it known that I, THOMAS V. ALLIS, a citizen of the United States, and a resident of New York city, in the county and State of New York, have invented new and useful Improvements in Barbed MetallicFencing, of which the following is a specification.
My invention relates to barbed metallic fencing consisting of a plain flat strip having laterally-projecting barbs produced at intervals along one edge by cuttinginto and along the strip on said edge, so as to separate narrow spurs a short distance along the strip and bending them laterally, some in one direction and some in the other.
My invention consists of an improvement in the form in which the barbs are produced, and are laterally projected, said barbs being longer than is required for the lateral projection, that they may have a flexible or yielding portion between the projecting part and the connection at the base with the strip, all
as hereinafter fully described, reference being made to the accompanying drawings, in whicht Figure 1 is a side view of the strip, showing the manner in which it is out preparatory to the bending of the barbs. Fig. 2 is an edge view of the same after the barbs have been cut and bent. Fig. 3 is a side view of the barbed and twisted strip in the complete form. I take a plain fiat strip a, of the usual size and form for such fencing, and make longitudinal slits I) through it at intervals in a line nearer one edge than the other, according to the required width of the barbs c that I wish to produce, said slits being thelength of two barbs, including their supporting-arms, and being apart from each otheralittle more than the required length of two base-webs cl, by which the barbs remain joined to the rest of the strip. At the middle of the length of these slits I sever the narrower portion of the strip diagonally by cuts 6, to enable the severed parts to be bent laterally for the barbs and to point the same. At the middle of the base-webs d I make the notches f in the outer edge of the strip, and at the bottom of the notches the short longitudinal slits g in line with the longer slits Z2. These notches and slits provide for the twist taking effect between the base connections of the barbs, so
that the strip twists more unitorm than it would without them, and the notches add materially to the symmetrical appearance of the fencing, besides allowing of the removal of surplus metal not needed or serving any useful purpose in those parts of the strip. The short slits result from a construction of the notch-forming dies, the purpose of which is to avoid in said dies the sharp irregular form of the notches. Between the notches fl make the long shallow concave depressions in the edge of the strip shown in the upper side of Fig. 1, the purpose of which is to taper the barbs slightly from base to point and remove the unnecessary excess of metal that they would contain if made as wide throughout their length as it is necessary to have them for the requisite strength of connection at the base with the strip. It also serves to make the barbs less clumsy and more symmetrical in appearance. These depressions and the notchesj are in practice out together by the same dies, the shape and length of which are such as to cut from one to the other of the outer extremities of two adjacent slitsg at one operation, so that it will be seen that the notches f, being made together with the tapering of the barbs, are produced without extra cost. The slitsb are made considerably longer than the barbs are required to project from the strip, for the purpose of the barbs being supported by an arm of elastic nature, that will yield and be less damaging to animals running violently or otherwise pressing hard against them, as I have before shown in my application for a patent, filed April 11, 1889, Serial No. 306,757, in which case the barbs are bent at right angles to the arms, and the arms are parallel with the strip; but my invention now consists in the construction of these supporting-arms in the laterallycurved form, projecting from the strip reversely to the projection of the barbs, as shown at 'n, Fig. 2, so that the barbs are bent from the strip first to one side and thence backward and across the strip to the other side, and the bend is curved so as not to strain the metal so rashly as when the barbs are turned by an angular bend from the arms remaining parallel to the strip.
hat I claim, and desire to secure by Letters Patent, is- I 1. The improved barbed fencing in which the integral barbs projecting from the edge of a thin flat strip have a supporting-arm between the projecting part and the base con nection with the strip, that forms the lateral curve projection on the opposite side of the strip and supports the barb across the edge of the strip, substantially as described.
2. The improved barbed fencing in which the integral barbs projecting from the edge of a thin flat strip are produced in couples from opposite ends of adjoining base-webs, joining them to the strip and separated by a notch between them, substantially as described.
3. The improved barbed fencing in which the integral barbs projecting from the edge of a thin flat strip are produced in couples from opposite ends of adjoining base-webs, joining them to the strip and separated by a notch and said strip having short slits at the bottom of the notches, substantially as described.
4. The improved barb-fencin g strip in which the integral barbs projecting from the edge of a thin flat strip are produced in couples from opposite ends of adjoining base-Webs, joining them to the strip and separated by a notch between them, and said strip having a slit at the bottom of the notch, and said strip being twisted, substantially as described.
5. The improved barbed fencing in which the integral barbs projecting from the edge of a thin flat strip have a flexible portion or supporting-arm between the projecting part and the base connection with the strip, said barbs being tapered on the outer edge from the base, substantially as described.
In testimony that I claim the foregoing as my invention I have signed my name, in presence of two Witnesses, this 8th day of June, 1889.
