COMPOSITION FENCE-POST.

Specification of Letters .Patent. Pafontefl Nnv, 25-, 1 91 3,

V Application filed August 13. 1912. Serial No. 714,920.

To all 20110221 1' i may concern Be it known that I, Rt'ssELL B. IiE YNETT, citizen of the United States. residing at I 'esterville, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Composition F ence-Posts, of which the following is a specification. I

This invention relates to the manufacture of composition posts, more particularly of 1 the type shown in Letters Patent No.

829,940, granted to me September 4, 1906. The objects of the present invention are to produce a post of vpronounced,durability and strength with minimum quantity of material, to provide a reinforcement which will not be displaced during the molding of the post and in which the longitudinal elements will be held in fixed relation; and to provide a reinforcement of truss-like form which will not interfere with the in sertioh of the staple-receiving composition.

The invention consists in certain novel features. all of which will be hereinafter first fully described and then more particularly pointed out in-the claim following the description.

The invention is illustrated in the accompanying drawings, in which:

. Figure 1 is a perspective View of a reinforcement for composition posts showing the parts of the same assembled before the post is formed around the same; Fig. 2 is a transverse vertical section of a mold showing a post formed therein; Fig. 3 is a detail plan view of a different form of brace or spacer for use in the reinforcement; Fig. 4 is-a transverse section of a mold showing a postformed therein and provided with a further form of reinforcement; Fig. 5 is a detail perspective view of the reinforcement shown in Fig. 4; Figs. 6, 7, and 8 are detail plan views of different forms of spacers.

In carrying out my invention, I employ a plurality of longitudinal rods or braces 1 which may be of any desired number according to the outline desired for the finished post. I prefer to make the posts substantially triangular in horizontalsection, as I have found that this form avoids unnecessary weight and bulk, while possessas clearly shown, the reinforcing rods passing through openings provlded therefor at the angle-and at the ends of the spacers.

In Figs. 1 and 2, the spacers are shown as provided near their ends and in their outer edges with notches 3 whereby shoulders 4 are formed, and on their inner edges at their ends they are rovided with the enlargements 5 where y sufficient metal is 4 formed around the rod-receiving opening to support. the rod and prevent the detachment of the spacer therefrom.

The reinforcement, consisting of therods or bars and the ties or spacers fitted thereon, is placed within a mold 6 which is approximately triangular in cross section, and the concrete or other cementitious composition? is poured in to the mold so as to entirely fill the same around the several elements of the reinforcement. It will be readily noted upon reference to Fig. 2 that the shoulders or corners 4: of the reinforce ment engage the lower -downwardly converging walls of the mold so as to support the reinforcement in proper spaced relation to the mold and permit the plasticcomposition to entirely fill the space between the reinforcement and the side of the mold so that the metallic members of the reinforcement will be entirely inclosed by and embedded in the composition of the post. The mold will, of course, beof a length corresponding to the height desired for the post,

' and the longitudinal reinforcing bars will be located at the corners of the post and will extend the full length of the same.

The'spacers or tles, by which the longitudinal reinforcing rods or bars are held in their proper spaced relation within the mold while the post is being poured, may be of various forms and I have shown several which rove efiicient. In Fig. 3, the spacer is su stantially of the same form as that shown in Fig. 2, except that on its outer edges, near its angle, it is provided with outstanding spurs .01 teeth 8 and inits inner edge, adjacent its lower end or its angle, notches 9 are provided. In the form shown in Fig. 6, two spurs or teeth 10 are formed on the outer edges of the spacer and two notches or recesses-11 are formed in each inner edge thereof. In Fig.,7, is shown a form of spacer in which the recess 3. indicated in the previously described forms, is omitted, and the shoulder 12 springs directly from the straight outer edge of the spacer. In this form, also, the enlargement 13 is reduced toward the end of the spacer and is disposed at an obtuse angle thereto in its lower portion, instead of being s'emicircular, and the opening-14, to recelve the bracing'rod, is somewhat lower in the spacer. In Fig. 8,-- the spacer is shown without the enlargement on the inner edge thereof, the

- straight edge 15 of the end of the spacer being reduced and the inner edge 16 thereof being straight.

The several forms of spacers just de;

scribed are. easily stamped out of sheet metal, and, with the exception of the formshown in Fig. 7, a. large number of the spacers may befistamped from a single strip of metal without any waste, while in the form shown in Fig. 7 may be produced with only so much waste as will be included between the lines of the inner edges of the main portion of the'spacer "and the highest point of the enlargements 13. It is not slightly necessary, however toemploy sheet metal contact with the bottom of the mold and the composition for the post may be poured into the mold so as to flow entirely around the members of the reinforcement.

It will be readily noted from the foregoing description, taken in connection with the accompanying drawings, that I have provided a construction in which it will be impossible to displace the members of the reinforcement during the molding of the post and that thepost may be rapidly and cheaply produced, and when produced, will be efl'e'ctually reinforced-at the oints where the strain is usually applied t ereto. The longitudinal reinforcing bars, which will be apex an ment, as the distance between the ties or spacers is short, and it will, consequently, be practically impossible to break the post. The spacer cannot buckle, as it is held firml within the concrete, and any strain whic would tend to force apart the rods passing through the ends of the spacers must first crush the concrete below the point where the strain is applied, and this strain will be resisted by the tensile strength of the spacer at its angle.

As the ties or spacers are V-shaped or have open tops, they offer no obstruction to the pouring of the cementitious material into the mold nor do they interfere in any degree with the proper location of the staple-receiving composition strip, indicated at 21. I

What I claim is:

A fence post comprising a substantially triangular body, a plurality of V-shaped spacers embedded therein and having their sides substantially parallel with the faces of the body leach spacer. having an eye at its d at each terminal and provided with a supporting projection on each outer side near each terminal, said projections constituting suspending points disposed between' the terminals and the apex of the spacer, rods inserted through and inclosed and supported by the eyes in the s acers, and a penetrable composition in one ace of the body between the terminals of the spacers. In testimon whereof I aflix my signature in presence-o two witnesses.
