J I -J Patented Apr. 10, 1934 UNITED STATES PATENT OFFICE 1 Claim.

The object of my invention is to manufacture a reenforced concrete fence for use on residences and, in general, wherever ordinary wire or ornamental iron fences might be employed. My

5 fence is made in sections consisting of one post, two rails and any desired number of pickets, the pickets being integral with the rails and the rails integral with the post so that the entire section is integral and indetachable.

My invention is illustrated in the accompanying drawing, in which Figure l is the elevation; Figure 2, the plan; Figure 3, the right end view; and Figure 4, the left end view. A variation of the fence section as shown in Figures ll,

inclusive, appears in Figures 5-8, inclusive, which are consecutively the elevation, plan, right end View and left end view. The difference in the above two fence sections consists in the location of the picket axes with respect to the axes of the rails.

In each of the above fence sections, one side of the post may be notched, as shown in the sketches, to provide a seat for the rails of the adjacent section at the end where there is no post. This support of the rails by the post is, of course, brought to bear when the sections of the fence are installed in the field; the installation consisting simply in placing the posts in the ground in a suitable manner. Longitudinal expansion of the rails is allowed for by leaving a space between the free end of the rails and the inside vertical face of the notch in the post.

Or, in each of the above fence sections, the

notch in the post may be omitted; in which case, after the post is placed in the ground, the rails will act as cantilevers from the post.

Each entire fence section may be poured in one continuous operation, in which event the entire section becomes a wholly continuous frame. Or, the pickets may be made first, allowed to set, and placed on the rail forms, after which the rails may be poured. Referring to the fence section shown in Figures 5-8 of the drawing, the

pickets must have anchors set in which will extend into the rails to provide a permanent connection to the rails. In the fence section shown in Figures 1-4, the bond. between pickets and rails provides an ample connection. The pickets may, of course, be entirely separate from the rails and attached later by means of anchorbolts, clips, or some other suitable method. In each fence section the rails may be poured continuously with the post; or, the rails may be made first, allowed to set, and placed on the post form, after which the post may be poured.

It is evident that the end section of any fence must consist of two posts instead of one as in the above described intermediate section. The additional post can be free until assembled in the field, in which case notches must be provided in one side to receive the rails, as in the one post of an intermediate section. Or, the additional post may be exactly the same and poured in the same manner as the post of an interme- 35 diate section; in this instance the end section will be a Wholly continuous frameconsisting of two posts, two rails and any desired number of pickets, both posts being integral with the rails and indetachable.

Each entire fence section is reenforced with either wire or reenforcing steel; and the amount of reenforcement and dimensions of the members may be varied.

-By using a small amount of water-proofing material, the concrete coverage on the steel and thus the area of concrete at any cross-section may be reduced.

Use of coloring materials, variation in picket lengths, and ornamental knobs at the tops of pickets greatly improve the aesthetic valve of the fence.

I claim:

A reenforced concrete fence made of interconnected sections, each section consisting of one post, two rails, and vertical pickets, the pickets being integral with the rails and the rails integral with the post so that the entire section is integral and indetachable.
