POST.

Specification of Letters Patent.

Patented Dec. 5, 1905.

Application led September 15, 1905. Serial No. 278,681.

The object of this invention is to provide a post that will combine the indestructible characteristics of concrete with the non-breakable characteristics of wood or metal and that will provide ready attachment for rails, wires, or

' other material used in building fences.

The invention is exemplified in the structure hereinafter described, and it is defined in the appended claims.

In the drawings forming part of this speciication, Figure 1 is a vertical section through a fence-post embodying my improvements and adaptedto support horizontal rails to which pickets or other fence material may be attached, and Fig. 2 is a vertical section` through the same post on a plane at right angles with the plane of the section in Fig. l. Fig. 3 is a perspective representation of the post shown in Figs. 1 and 2. Fig. 4. is a perspective representation of a corner-post for fences, which embodies the principal features of my invention and is adapted to sustain barbed orother fence wires. Fig. 5 is a vertical section through a fragment of the post shown in Fig. 4..

The body 1 of the post is composed of concrete or a compound into Which cement enters. The lower part of the post has the lateral extensions or enlargements 2, of concrete, for a purpose to be hereinafter explained, and an anchor-bar or T-base 3 is formed crosswise of the lower end of the post. A bar 5, of wood or metal, is inclosed in the concrete lengthwise thereof and is provided at its lower end with a cross bar or rod 6, which extends into the opposite ends of the T-base or anchor 3. When the post is intended to carry the horizontal rails of a picket fence or other fence analogous thereto, the bar 5 is provided at its upper end with a strap 7, which protrudes through the upper end of the concrete body in the form of a threaded bolt and is adapted to extend through the upper rail of the fence. A nut 8 on the upper end of the bolt extension 7 is used to secure the rail firmly to the top of the post. Gains, as 4., are also formed in the rail-sustaining posts, and bolts are extended horizontally through the posts to hold the lower rails in the gains. Side strips 9, of Wood'or metal, are embedded in opposite faces of the concrete body flush or approximately iiush with the surfaces of the post, and they are secured by bolts, as 10, which extend through the strips, through the concrete, and through the central bar 5. From lines slightly above the ground-surface Athe strips 9 are incased in the concrete by lateral enlargements 2, so that all surfaces in contact with the soil are concrete, while the wood or metal extensions are made to strengthen the post throughout practically its entire length.

When the improved post is used as a cornerpostof a wire fence, it is preferably braced, as shown in Figs. 4 and 5, by means of oblique braces 1Q, which extend to the short concrete posts 11. The strips 9 are supplied with short wires 13, to which the fencewires are subsequently attached, and as a matter of preference the short Wires are looped around pins 14. inside the strips 9, as shown in Fig. 5. shown the stress of the wires is from the center of the post and between the two braces, so that there is no tendency for the posts to turn in the ground as the wires are tightened. The concrete body is practically indestructible so far as action of the elements, including fire, is concerned, and the wood or metal bars and strips form with the concrete a trusslike structure which gives the tensile strength needed to insure against breakage by any ordinary or even extraordinary jar or strain. Above the Vground the outer strips are exposed to facilitate attachment of fence material and to increase the strength of the post without adding materially. to its cross-sectional dimensions; but below the ground-line the wood or metal is not exposed to the rotting or rusting action of moisture. The anchor-foot 3 adds to the stability of the post when the post is set into the ground and the cross-rod 6 stays the anchor foot against breakage.

In the drawings the post is shown plain; but it is obvious that it may be ornamented to any desired extent by providing molds shaped to give the desired conguration.

Having thus described my invention. I claim as new and desire to secure by Letters Patent- 1. A post comprising a concrete body, a bar l of non-plastic material incased in the concrete lengthwise thereof, strips of non-plastic material embedded in opposite faces ofthe concrete body lengthwise thereof, and bolts bind- With a corner-post braced as IOO IIO

ing the strips, the concrete and the central bar together.

2. A post comprising a concrete body, a bary of non-plastic material incased in the concrete body lengthwise thereof, bars of non-plastic material embedded in opposite faces of the concrete body lengthwise thereof, bolts binding the bars together and tothe concrete and side enlargements of the concrete incasing the side bars below the ground-line of the post.

3. A post comprising a concrete body, a cross formation of concrete on the lower end of the post, a bar of non-plastic material incased in the post lengthwise thereof and provided with a cross bar or rod on its lower end which extends into the cross vformation of concrete, strips of non-plastic material embedded EUGENE R.
