' Be it known MICHAEL KELLY, of the As an additional means of security the thorns city and county of New York, and Sta-teof maybe griped in suitable machinery before New York, did invent a new and useful In inserting them in the wire, so as to compressproyement in Metallic Fences, which is fully them near the middle and thus adapt them to set .forth in the-following specification, referbe more readily locked. After such com-presence being bad to the accompanying drawsionthe thorns will present the appearance ings, in which-.- shown in Fig.8 of the drawing.

Figure 1 is a plan viewof a portion of the j The thorns may be'set in'the wire after the wire with the thorns in place, the who being fence is erected, if necessary in any case, but a flat strip and presented. edge upward. itis preferable to set thethorns by hand or Fig. 2 is a side view of the same, representby .n aehinery before the wire has left the in g the wire after the holes have been marked, nanni'ac'tory. It is-also preferable to form the or slightly cut through by a sharp instrument thorns of metal which isa little softer than the wire, so that-in 'the'act of compression the before they have been spread open.

Fig. represents a cross-section taken on the line m, m, Fig. 4. Fig. 6 is aplan view of a modification, in which the thorn is made in theform of a common tack. Fig. 7 represents the tack: separately before its connection with the wire,- and Fig. 8 represents a thorn prepared from common round wire, cut obliquely.

. The object of this invention is to improve the construction of fence-wires carrying thorns, or pointed pieces of metal.

The. invention consists in the use oi a flat wire through which holes are made, in which thorns are inserted and secured.

In the drawings, A is a flat wire, roiled, or otherwise prepared in lengths of any desired extent. Through this wire holes care produced by punching or otherwise, 'by hand, or by machinery.

' The thorns B are made from common round wire, by cutting it oh obliquely, as clearly shown in Fig. 8. They may be cut by hand or by machinery, and by cutting thenrobliqnely, a sharp pointis secured at each end without loss ofmaterial, and with very little labor.

The thorns B are thrust into the holes a in the wire, and are there retained by compressng the wire upon the throne by a blow with a.

wire-at such distances apart as may be desired. The wires A are represented in the draw"- angles, as indicated'at A. The lengths of thorny wire may be attached to posts set at suitable distances apart, by driving the bent en therein,.or they maybe attached in any other suitable manner, as the method of their attach ment forms no part of the'present invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is-- holes in the wire, substantially as described. 2. Dhemethod herein described of attaching thorns or barbs to a fence-wire, by insertpressing the wire and the barbs forcibly together, substantially asdescribed.
