FENCE.

SPECIFICATION forming part of Letters Patent No, 388,816, dated September 4, 1888.

Serial BT05271493.

(No modali To alZ whom it may concern:

Be it. known that I, DAVID BOYD, a citizen of the United States, residing at Louisville, in the county ofJefferson and State of Kentucky, have invented new aiid useful Improvements in Fences, ot' which the following is a specification.

The invention relates to improvements in .fences ofthe crossbrace variety, the main ob- ]ect being to prevent both lateral and longi tudinal displacement of the felice by means of the said cross-braces, which are the fence-posts; and it consists iu the construction and novel combination of parts hereinafter described, illustrated in the accompanying drawings,and pointed out in the appended claims.

Figure l of the drawings represents a perspective view of part of a fence embodying the invention. Fig. 2 represents a vertical section on the line m a of Fig. 1. Fig. 8 is a detail perspective view showing the upper ends of the braces detached.

In the drawings, A designates a fencepost composed of the two crossbraces B B, inclining upward from one side of the fence, and the crossbrace U, inclining similarly from the opposite side, the said braces being preferably tapered toward their upper ends. rIhe braces B are provided with notches b in their adjacent or facing edges at equal distances below their upper ends, and with the senii-eircumferential grooves b im niediately below their tops, and the brace C has a siinilarly-situated circumferential groove, c. The adjacent snrfaces of the braces B at and below their tops are Ilattened, as at b2, so that they may lie closely together, and the brace C has its side edges inserted in the notches b of the braces B, after which the tops of the latter are then bound tightly together by a wire, I), several turns of which are made in the semi-circuni ferential grooves b. The two sides or strands d d of thc wire are then twisted together or crossed on the upper side of the rider-rail G, (which is arranged in the upper angle formed by the intersection of the braces) after which one of the sides or strands, d, is carried down ward, and the other side or strand, d, is carried across and wrapped one or more times around the upper end of the brace C inthe circumferential groove c. The side or strand d is then carried inward over the rider G, and

carried downward on the opposite side of the saine from the side or strand (l, and the two sides or strands are united and twisted firmly r together below the intersection ofthe braces in the lower angle formed by said intersection. It will be observed that the sides or strands thus pass down on opposite sides of the rider, and also on opposite sides of the braces B B, and, being united both above and below, they thus embrace the said rider, and the intersec tion of the braces bind them iirmly together. The lower ends of the braces B are separated by having their upper ends bound in contact and by insertion ofthe brace C below said ends, and to bind the latter brace securely in place a wire loop, E, is firmly secured around the braces B near their lower ends, in order to make the notches b bear strongly against the opposite sides of the brace G. Below the forks ofthe braces the strands are twisted together at intervals, leaving as many loops F between them as there are to be rails H in the fence panel. Below the lowest of said loops one strand, d, is carried to one side and wrapped tightly around the brace C near its lower end, and the other strand is carried to the other side and firmly secured to the inner side of the loop E. In this construction it must be noted that each fence-post A, composed of three braces and the connecting-wires, has three points ot' support, which forni a triangle, and will resist displacing force from all directions, and that the diagonals of the braces lie in the lines of direction of both lateral and longitudinal strain, giving greater stiITness and less liabilA ity to breakage. rIhe said posts may be made independently and under cover, and when made are set up with the feet of the braces resting on the ground at suitable distances apart, and the riders inserted in the upper forks of the braces with their ends lapping under the wire D. The rails H are then inserted in the loops F, their ends lapping therein, either vertically or laterally, as most convenv ient. The said rails and riders may be of any cheap material, such as split rails, poles, de.

If desired, the cross-braces B may allbesitnated on one side of the fence; but they are preferably arranged alternately on opposite sides thereof, as thereby the lateral resistance on each side will be equal.

Obviously the weight of the panelrails is IOO sustained by the upper ends ofthe braces, and therefore there is a tendency to spread the lower ends of the braces laterally. Therefore the lateral extensions of the strands d d are drawn taut and the lower end of the series of supporting-loops F is held rigid, thereby preventing a lateral swing of the panel-rails.

The upper ends of the braces maybe bound together by a separate wire from that which is employed to forni the supporting-loolris; but it will be understood that I preferably use a single continuous wire, as there is less dangerof separation of the parts of the felice, and, further, less wire is required when a continuous piece is employed.

Having described my invention, l claim- 1. The herein described fence post, composed of the three upwardlytapered crossbraces B B and (l, the diagonals of the crosssections of which lie, respectively, longitudi nally and laterally in relation to thcfence. the said braces B inclining from one side of the fcnee and being provided with the notches b' in their adjacent edges and having their tops flattened on their meeting surfaces, provided With semieircnmferential grooves b,and bound together by the wire D, and their lower ends connected by the wire loop E, and the said 1 l l i l l i l i l brace C inclining from the opposite side ofthe felice and having its side edges resting in the notches b of the braces B, substantially as specified.

2. The combination, in a fence, of the crossbraces B B, provided with the flattened meeting upper ends, b", the semicircular grooves and the notches b', the cross-brace C, havingits side edges in said notches, the wire D, binding together the tops of the braces B, connecting the same with the top of the brace Gand having the vertically descending strands d d', which form the loops F below the lower fork of the braces, the wire loop E, connecting the lower portions of the braces B and connected to one strand of the wire D, the other strand being seen red to the lower portion of thebrace C, the riders G, with their ends lapping in the upper forks of the braces below the wire D, and the rails ll, with their ends lapping in the loops F, substantially as specified.

ln testimony that l claim the foregoing as my own I have hereto alli red my signature in presence of two witnesses.

DAVID BOYD.
