SPECIFICATION forming part of Letters Patent No. 709,383, dated May 20, 1902.

Application filed August 29, 1901- Serial No. 73,704. (No model.)

To all whom it may concern.-

Be it known that we, ORIEN B. SMITH and FRED T. BISBEE, citizens of the UnitedStates, residing at Athens, in the county of Calhoun and State of Michigan, have invented certain new and useful Improvementsin Fence-Posts and we do declare the following to be a full,

clear, and exact description of the invention; such as will enable others skilled in; the art to which it appertains to make and use the same, reference being had to the accompany:

ing drawings, and to the letters of reference strength to the structure and having a cover-' ing of cement or similar plastic material, the post being provided with projecting wire loops to which longitudinal fence-wires may be secured.

Figure 1 is a perspective view of a completed fence-post. Fig. 2 is a broken vertical section showing the internal construction of the post. Fig. 3is a-broken elevation of the corrugated-metal link which forms the skeleton frame of the post, and Fig. 4: is an edge View thereof. Fig. 5 is an elevation of the wire loops and the means for attaching the same to the skeleton frame.

The skeletonframe or tapered link A is made from flat bar metal corrugated in the direction of its width, except that the bends at the ends need not necessarily be corrugated. The bar of metal is bent edgewise to the form of a tapering link, and the ends of the bar are connected so that the corrugations extend in direction transverse to both sides of the link, as indicated in Figs. 2 and 3. The corrugations may be applied to the metal either before or after it is bent into link form. This transverse corrugation of the bars of the linkis for the purpose of increasing the strength and stiffness of the skeleton frame when the same shall have been embedded in the cement covering and also to enable the cement to adhere more closely to the frame or skeleton. link gives a bracing efiect.

, the loops projecting, as shown. I

The tapering of the A wire 13 has loops or bightsO, formed by bendsin the body. of the wire atsuch distance apartas'may be advisable to form fas-.

tening attachments for wires to be strung on the posts. The number of these loops or bights'jC is as great as desirable, and their. projection is suficient to carry the bend or loops having been constructed as described,

the whole is inclosed in a suitable mold or casing, and a body E, of cement or. similar plastic material, is formed around this skeleton, the'loops (l projecting from the side of the cement body. 'When the material has hardened, the skeleton frame and the wire loops will be firmly embedded therein, with As the strain of the line-wire of the fende is apt to be mainly transverseflto'the li'ne of the fence, the greatest strength of the post will be in line to resist suchstrainenamely,

transversely to both bars of the skeleton link.

Nevertheless the corrugations to the links give marked stiffness to the post in the direction of the width of the post which is of course in direction of the lengthof the fence,- and the wire loops being all connected inside the cement body and also.v firmly bound to skeleton frame are, in position to resist great strain inany direction.

We employ any of the usual 1 plastic .com pounds for the body of thepost.

What we claim is- 1. A composite fence-post consisting of a sheet-metal link with wire loops connected to one side bar thereof and projecting outwardly, and a cement covering for said-link and wire except the outer bend or bight of the-loops.

2. A composite fence-post consisting of a sheet-metal link havingits sidelbarscorrugated transversely, a connected series of wire loops attachedto one of the side bars of the link and projecting outwardly, and a composition covering the link and all but the outer extremities or bights of the wire loops.-

3. A composite fence-post having a sheet- In testimony whereof we affix oursignatnres metal skeleton formation composed of a tain presence of two Witnesses. pered metallic link corru ated transversely, r a series of connected wirz loops rigidly secured to one bar of the link and projecting therefrom, and a composition covering for Witnesses:

the link extending nearly to the outer turn CHAS. A. STANDIFORD, of the loops, all substantially as described. E. D. ALBERTSON.
