I REENF'ORCED CONCRETE FENCE POST Filed March 22, 1927 Patented Get. 22, 1929 UNETED STATES ATLAS M. THOMPSON, OF GROTON, NEW YORK REENFORCED CONCRETE FENCE POST Application filed March 22, 1927. Serial No. 177,367.

This invention relates to improvements in reenforced concrete fence posts.

The primary object of the invention is to provide a concrete post which is reenforced in such a manner as to withstand all strains and stresses to which such a post is subjected,

and particularly while in use as a fence post.

A further object of the invention is to provide a post of the above referred to character with novel supporting means for fence runners or wires.

Other objects and advantages of the invention will be apparent as the description proceeds.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevational view, partly broken away, of one form of fence post embodying this invention,

Figure 2 is a side elevational view of a slightly modified form of post,

Figure 3 is a. side elevational view of a further modified form of post,

Figure 4 is a side elevational view of a still further modified form of post,

Figure 5 is a horizontal sectional view of the type of post shown in Fig. 3, and

Figure 6 is a horizontal sectional view of 7 another form of post which is aslight modification of the form shown in Fig. 3.

In the drawings, wherein for the purpose of illustration is shown a preferred embodiment of this invention, the numeral 10 designates the enlarged base portion of a fence post shown in Fig. 1. This base portion is substantially rectangular in side elevation and has projecting perpendicularly there.

from the substantially triangular portion 11 which merges into the extension'12. It is to be understood that the entire body portion of this post is formed'from a suitable con crete or cement mixture and is reenforced by the vertically extending spiral wires or rods 13 which are positioned relative to each other so as to properly reenforce a straight vertical portion of the entire post, the said portion being a true continuation of the extension 12. The remainder of the base portion 10 and the, triangular part ,11 are reenforced by pose of connecting the strands of wire vform-' ing a fence to the post, the triangular part 11 and the vertical extension 12 are formed with the tubular, wire guides 15 embedded therein and extending horizontally, the wire fence being represented in its entirety by the reference character 16. y

In the form shown in Figure 2, a slightly tapered post 17 is provided and is reenforced by the nested spiral strands of wire or rods 18. Connected to certain ones ofthe convolutions of these two reenforcing elements 18 are the laterally projecting fence wire tie elements 19 which are partially embedded in the concrete of the post body 17 and are formedv into hook ends 19'.

In the form of fencepost shown in Figures 3 and'5, a concrete body 20 is provided, of any desired shape. This body is reenforced by the criss-cross type of reenforcing rods 21- which are arranged with respect to each other so as to reenforce the entire body of the post. This type of post is formed with surface grooves 22in one side thereof to receive the wire cable 23 forming the fence.

It is considered that this post is especially.

adapted for'guarding turns and ditches on highways. To secure the wire cables 23 to the post, the latter is formed with horizon tally extending holes 24: which merge into the} grooves 22, atone end and function to receive the tie elements 25; The wire cable engaging end of each element 25 is hook shaped, as at 26, while the end projecting from the opposite end of the post hole 24 is threaded to receive the nut 27 This same general type of post may be formed as shown in Figure 6. This form shows a body portion 28 having a horizontally extending hole 29 which runs in the direction of the wire cable 30, the latter passing through the said hole. Of course, as many holes 29 as desired may be formed in this type of post.

In the form of post shown in Figure 4, the body 20* is reenforced in the same manner as the body 20,see Fig. 3, as by the zig-zag type of reenforcing rods of wires 21 This post has secured thereto, as by the bolts 31, tie strips 32, formed of a suitable metal or wood, which are provided with bolt receiving apertures 33 at their opposite ends. Through these apertures are passed bolts, or the like, employed for supporting heavywooden runners 34. This type of post and fence construction is especially adapted for highway service to protect traflic from turns and gulleys or ditches along the side of the same.

It is to be understood that the forms of this invention shown herein and described are preferred. However, various changes in the shape, size and arrangement of parts may be madewithout departing from the spirit of the inventionor the scope of the subj oined claims.

I claim as my invention:

1. A post, comprising a rectangular base portion, a triangular portion extending perpendicularly of the base, and a reduced extension projecting from the-triangular portion; one wall ofeach of the base portion, the triangular portion and the extension coinciding in a vertical-plane, reenforcing means extendingthrough the base portion, triangular por tion; and reduced extension and arranged in parallelism with the aforesaid coinciding walls, and a reenforcing element extending through the remaining parts of the triangular portion and base portion and. arranged substantially in parallelism with the hypotenuse of the triangular portion, said reenforcingr members being-independent. of each other and eachlfor-med in a continuous spiral throughout its length.

2. A post including three portions ofsubstantially equal height and comprising a rectangular base portion, a triangular portion located above the base portion and a reduced extension projecting perpendicularly of the last mentioned-portion, a set of reenforcing members extending through all of said portions, and a second set ofs'reenforcing membersex-tendingthrough the base and triangular-portionsand arranged at an angleto the first setof members.

Intestimony whereof I affix my. signature.

ATLAS M. THOMPSON.
