BARBED-ME TAL-STRIP FENCING.

SPECIFICATION forming part of Letters Patent No. 305,354, dated September 16, 1 884.

Application filed March 9, 1882. (No model.)

To all whom it may concern:

. Be it known that I, ANDREW J. UPHAM, of

Sterling, in the county of W'hiteside and State of Illinois, have invented certain new and use ful Improvements in Barbed-Metal-Strip Fencing; and I do hereby declare that the following is a full,clear,and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and in which- Figure 1 represents a side view of a section of my improved barbed-metal-strip fencing. Fig. 2 represents an edge view of the section of fencing shown in Fig. 1; and Fig. 3 represents a section on line 00 m, Fig. 2, looking in the direct-ion of the arrow of the same figure.

The natureof my invention consists in the combination,with aflat metal st-rip,of asheetmetal barb stamped or out out and attached thereto in a peculiar manner, to be hereinafter more fully described.

To enable those skilled in the art to which my invention belongs to make and use the same, I will proceed to describeit more in detail.

In the drawings, the part A represents a section of a thin strip of metal, such as is suitable for making fences. The part B represents a sheet-metal barb stamped or cut out of a strip of thin metallic material. It is provided with two points, a a.

My improved barbed fencing is constructed in the following way: A slit or opening is made along the center line of the strip A at regular intervals,as shown at b,Figs. 1 and 3. Through this opening is inserted one end of the fiat metal barb B. Half the length of the barb is passed through the opening I), each end a a extending out in a straight direction from the strip A. The part c is then bent or folded over I one edge of the strip, and pressed down so as other side of the strip A, the two ends a a being left projecting out in opposite directions, as fully shown in Figs. 1 and 3 of thedrawings. The barb B having been inserted or passed through the opening b, the parts 0 and (1 may be bent or folded over at the same time and by one operation.

If preferred, in the manufacture of my improved fencing, mechanism maybe employed so as to press one half of the strip A at the opening I) in one direction, and the other half in an opposite direction, whereby one end of the barb B may be run through said opening or slit while resting upon the side of one half of said strip, in which case the ends of the barbs would not have to be bent so far to bring them into the position shown in Fig. 3 as they would in the mode of manufacture first above described. In eitherof themodes above described the operation of bending the barb I ANDREYV J. UPHAM.
