FENCE-POST.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed February '7, 1907. Serial No. 356,207-

T0 at whom it may concern:

Be it known that I, WELLs M. RUeeLEs, a citizen of the United States, residing at Mellen, in the county of Ashland and State of Wisconsin, have invented certain new and useful Improvements in Fence-Posts, of which the following is a specification.

This invention relates to fence posts.

One object is to provide a fence post embodying such characteristics as to embody a maximum of strength and a minimum of material.

A strand wire stretched tight and made fast to the top of fence posts contracts in cold weather to such an extent as to break the wire or pull the fence post over bodily in the direction of the strain upon the wire. If the strain of the wires were equal between the posts, this would not happen on a line of posts. But these strains are never equal, resulting in one post being subjected to greater strain than another. Consequently, unless the posts of a fence are elastic or resilient enough to equalize the strain from the strand wires that are made fast to and stretched upon them, the strand wires will break or the posts must give bodily. The result is that either the fence wires are broken or the posts are loosened in the ground. In either case the result is disastrous to the fence.

It is therefore another object of my invention to provide each post withv an elastic top so as to prevent breaking of the top wire of the fence on account of expansion or contraction incident to climatic conditions.

A still further object of my invention is to provide afence post rigid and solid at its base,

and from its base line to its top possessing resiliency or elasticity enough to equalize the strain of the fence wires attached to it.

With the above and other objects in view, my invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes may be made in the form, proportion, size and minor details without departing from the spirit or sacrificing any of the advantages thereof.

In the drawings Figure 1 is a front elevation of one form of my invention. Fig. 2 is a side elevation. Fig. 3 is a detail view of the panel. Fig. 4 is a perspective view of a modified form of invention. Fig. 5 is a detail view of the inner member of the modified form. Fig. 6 is a detail view of one ofthe post tensioning members; and Fig. 7 is a perspective view of another form of my invention.

Referring now to the accompanying drawings and more particularly to Figs. 1 to 3, inclusive, it will be seen that in one embodiment of my invention the post comprises an upright member 1 composed preferably of steel wire bent intermediate its ends to form the upwardly converging members 2 and 3 twisted together at their upper ends as at 4:, and terminating in the short diverging elements 5 to which latter the top line wire 6 may be secured in any suitable manner. This u right constitutes the outer member of one orm of my improved 0st and it is so formed that it may receive ldetween its upwardly diverging portions 2 and 3 the wood or other panel 7 having each end provided with a recess 8, the upper recess fitting in the crotch at the base of the twisted portion 4, and the lower recess embracing or fitting over the lower end or bight portion of the outer member 1. By reason of the material employed in the formation of this outer memher the post embodies considerable elasticity and may yield longitudinally or laterally.

To permit of the insertion of the panel or.

other inner member 7 within the outer member of the post, the latter must possess more or less slack, and the filling or base material of the post, to be hereinafter described, is not capale of taking up the slack entirely nor would the filling stay in place were it not for the fact that I employ the tension rings 9 which are of difierent size and embrace the converging members 2 and 3 of the outer member. These tension rings 9 difier in size according to the diameter between the converging bars 2 and 3 of the outer member. When the tension rings are slipped upon the outer member and made tight thereupon the 0st is in tension and the filling material is field in place. Thus the tension rings perform a dual function.

The top wire is the principal wire of the fence and the one that causes the most trouble incident to contraction and expansion, and for this reason I provide for increased resiliency, elasticity, or yieldability at the outer or top end of the post. The top line wire 6 may be secured to the diverging elements 5 of the twisted portion 4, as already explained, or if preferred it may be secured in any suitable manner to the twisted portlon below the dlvergmg elements 5.

The remaining or lower line wires may be secured to the panel or other inner member 7 in any suitable manner, or if preferred, the lower line wires may be secured to the converging parts 2 and 3 or to the tension rings 9, as may be desired. No.matter how the line wires are secured to the osts, the latter return to their upright positions as soon as relieved of strain lncident to contraction and expansion of the line wires. It will thus be apparent that the 0st will be more or less elastic from its base ine to its top. The panel board is made of such material and of such thickness as to give it a chance to spring. The top wire being fastened to the top of the post independently of the other wires on the post, it is free to pull one way or the other without interfering with the center panel or other inner member to any great extent. If the fence is made of a single strand of wire on top and a woven wire fence fastened to the panel part of the post, the top strand or line wire would be free and independent of the woven wire material. A post of my improved construction may be sprung out of line six inches more or less at the top without breaking it and without moving its base. This elasticity at the upper end of the post is facilitated by reason of the fact that the top line wire is preferably wrapped around the diverging elements 5, as clearly shown in the drawings.

Makers of wire fences caution users of their products not to staple the wire too tight so that they may be free to expand and contract. It is not practical to follow such instructions in all cases, and the result is that the posts give bodily, or the line wires break. My posts are elastic, resilient or yieldable at their upper ends, or from the base line to their upper end, overcoming bodily movement of the posts or the breaking of the line wires incident to climatic conditions or too tight engagement of the line wires with the osts.

The base of the hereinbefore described post is formed preferably by disposing the longitudinal bars 10 upon opposite sides of the panel 7. Between the longitudinal bars 10 and the lower portions 2 and 3 of the outer member I prefer to dispose the filling blocks 11, and if desired, I may key up the bottom of the post by the insertion of one or more wedges a between the longitudinal bars and the filling blocks as best shown in Fig. 1. These longitudinal bars may terminate at the base line or they may extend thereabove, as may be desired, the bars and filling blocks being obviously formed of wood, concrete, or any suitable material.

In Figs. 4 to 6, inclusive, 2 illustrates another form of my mvention, 1n which the outer member 12 instead of having a panel the wire inner member 13 formed in exactly the same manner as the outer member 12, gpept for the formation of a depression to provide a recess 14 at its lower end to embrace the lower or bight portion of the outer member. The upper end of the inner member is twisted, as is the outer member, and has the diverging elements or prongs 15 resulting in a recess designed to fit in the crotch at the base of the twisted portion 16 of the outer member. Arranged upon opposite sides of the inner member 13 are the longitudinal strips 17 and the filling blocks 18, suitable wedges (not shown) being used, if desired, to key the base portion of the post, as in the first form described. In this second form of invention, I employ tension members 9.

From the foregoing it will be understood that in either form of invention described I provide an inner member adapted to be sprung or otherwise fitted into engagement with the outer member, either inner member having a recess or its equivalent at each end.

In Fig. 7, I illustrate still another form of invention. In this view I illustrate the form first described embedded in a concrete base 20, and obviously the second form of invention may be embedded in a similar base. I deem it unnecessary to illustrate it, but if desired, either form of invention could be embedded in a concrete.base without the longitudinal bars or filling blocks, the bars of the outer member of the post above the base line converging toward the upper end and tensioned by means of the aforesaid tensioning members or rings.

As shown in Fig. 1 it is not necessary to fasten the top strand wire to the top of each post, the top strand wire being held in its seat formed by the prongs 5 by twisting a short piece of wire 21 around the prongs after the wire has been stretched from one stretching post to another; so therefore, the top strand is free to expand or contract with regard to the stretching or other posts. Thus, the top strand wires may be fixedly secured to the top of some of the posts or loosely to others as just explained.
