BARDf-WIRE CHAIN FOR FENCES.

SPECIFICATION forming part of Letters Patent No. 391,502l dated October 23, 1889.

Application filed August 2T, 1888. Serial No. Q3.S77. (No model.)

To @ZZ whom it may concern.-

Be it known that I, JOHN J. BENSON, a citizen of the United States, residingin the city of Troy, in the county of Rensselaer and State of New York, have invented a new and useful Barbed-Wire Chain for Fences, of which the following is a specification, reference being had to the accompanying drawings.

The general obj ect oi' my invention is to produce a very effective, strong, durable, and cheaply manufactured barbed wire fencechain, which, when properly mounted in a fence, shall be greatly wider vertically than horizontally and furnish a conspicuous guard, and shall be nearly rigid in the plane of its greatest width or vertically, and easily iiexible only in the plane of its narrowest width or horizontally, and shall have barbs project out laterally from the two opposite widest sides of the chain. I attain this object by the constructions illustrated in the aforesaid drawings, in which- Figure lis an elevation of one side, and Fig. 2 a plan, of a portion of a barbediwire fencechain embodying one form of my invention. Fig. 3 is an 'end elevation and cross-section of the same at the line .e a in Figs. l and 2 and viewed in the direction pointed by the arrow y. Fig. lis an elevation of the other side of a portion of a chain similar to that shown by Figs. l, 2, and 8, and Fig. 5 is a plan of the same. Fig. 6 is a side elevation, and Fig. 7 a plan, of a portion of a barbed-wire fence-chain embodying a modification of my invention, and Fig. 8 is an end elevation and section of the same at the line ac x in Figs. 6 and 7 and viewed in the direction of the arrow w.

Like letters refer to similar parts in the several views.

Each of the links in my aforesaid barbed wire fence-chain consists of a single section of wire bent to forma pivot-bar, as a, at and across one end ofthe link, and two lengthwise rods, as b b', extending from the ends of said pivot-bar and widely apart fr0m each other directly to the other end of the link, two spirais, as c c', extending inward toward each other from the forward ends of said lengthwise rods and surrounding the like pivot-bar a of 5o the next link, and twobarbs, as d d', projecting outwardly from the inner ends of said spirals and laterally on the two opposite widest sides of the link, essentially as indicated in the aforesaid drawings. By having the links thus constructedand connected by liinge-joints,eonsist ing of the pivot-bars a and socket-spirals cc', having the barbs d d', the `chain is nearly or quite rigid atitsjointsin the plane ggf the pivotbars orgreatest width of the links and is t1eXible at the joints only in the planes at or nearly at right angles to the planes of the pivot-bars, so that the chain can be freely wound on a roll or reel for convenient handling and transportation, and so that when thechain is secured to upright fence-posts with the pivot-bars a, and greatest width of the links vertical, or nearly so, the chain is a conspicuous guard, as indicated by Figs. l, 4, and 6, and is nearly or quite inflexible in the vertical direction in which the gravity or weight of the chain tends to sag it down. At the same time the chain is very wide vertically and is iiexible laterally or horizontally, and has at the middle parts of every joint two barbs projecting laterally on opposite sides ofthe chain, so as to present gentle but effective warning and resistance to cattle coming in contact with either of its two upright or widest sides.

In making this barbed-wire fencechain from suitable wire sections any suitable method can be practiced-21s, for instance, by bending one of the wire sections so as to form the bar a and lengthwise parts b b', as indicated in the lefthand end portions of Figs. l and G-before or after ceiling the end parts ofthe wire section to make the socket spirals c c with barbs d d', as indicated in the righthnnd end parts of Figs. 1,2, 4t, 5, 6, 7. Then into the two adjacent spirals thus made insert to its middle another wire section and coil its end parts to make the two spirals with barbs and bend it to forni the end bar and lengthwise rods, and then insert into the adjacent spirals last made another section-wire, and bend and coil it; as above stated, and so on repeatedly.

In carrying out my invention the spirals c 0 of each link can be coiled in opposite directions or in the same direction, as illust-rated by the drawings. Fach spiral may have any suitable number of coils which shall prevent roo it from being unwound by the strains to which the fence-chain shall besub]l ect in use. I commonly prefer to have in each spiral at least two or three complete coils, substantially as 5 shown in the drawings.

I claim as my invention- A barbed-wire fence-chain in which each link consists of a single section of wire bent to form a pivot-bar at one end of the link and xo two rods extending from the ends of the pivotbar andwidelyapartfrom each otherto the other end of the link, two spirals extending inward toward each other from the forward ends of said rods and surrou riding the pivot-bar of the next link7 and two barbs projecting from the i5 inner ends of said spirals and laterally on the two opposite widest sides of the link, substantially as set forthn In testimony whereof I hereunto set my my hand, in the presence of two subscribing zo witnesses, this 24th day of August, 1888.

JOI-IN J. BENSON.
