Specification of Letters Patent.

Patented June 22, 1909'.

Application filed march 25, 1909. serial no. 486,836.

.and columns, the object beingtofprovide a stron and durable concrete or "cement post ment embedded t erein, extending longitudinally, and being bent to provide a series of radial arms, said arms having integral projections,.and being also provided with holes into which the concrete enters, whereby the reinforcement becomes strongly united with the concrete.

Another object is to provide a reinforced post or column of maximum strength'and durability, and of inexpensive construction, whereby the post or column is made avail able for ordinary and general use.

In the accompanying drawing, wherein I have shown one embodiment of my invention, Figure 1 is an elevation of a post constructed in accordance with the principles of my invention. Fig. 2 is a perspective view of the reinforcing member. Fig. 3 is a sectional view of a round post, taken on the line Fig. 5 a view 0 33 of Fig. 1. Fig. 4 is a sectional view illustrating a v referred arrangement of the reinforcement in a olygonal ost or column.

f part of .t e sheet metal showing the slits therein. Fig. 6 is a sectional view of 1part of the sheet metal showing the latera the slits.

The metallic portion or reinforcement consists of a sheet metal plate comprising a central portion 1, bent in o posite directions, as shown at 2 and 3, whereby the portions 4 are projections formed between caused to lie against the central portion. The edges or lateral portions 5 bend ou 'wardly substantially at right an les to the central portion. I Through laterally extending portions 5, and through the overlap ing portions 1 and 4 crossed slits are out, ant the triangular portions formed between the slits are bent laterally, providing lateral extensions 6. .These devices are formed in staggered relation on each wing or arm of the a sheet metal reinforce-- my hand, in the presence of two The reinforcement thus formed then inclosed in the mold and the cement or concrete is poured into the mold, thus entirely embedding the reinforcing-member, and entering the holes formed by the'extensions 6.

The projections 6, and the holes having the concrete therein, cause a strong union of the concrete and the reinforcement. At suitable intervals alongthe post grooves 7 are formed to receive the fastening devices whereby the wires, etc,, are secured'to the posts.

When a polygonal post is formed the Wings or arms of the .reinforcementproject toward the corners, as shown in ig. 4. Grooves 8, for like purpose as the grooves7, are formed in the corners of.posts of the polygonal form. a

I am aware that there maybe variations and modifications in the arrangement and constructionwithoutin the least departing from the spirit and sco "e of the invention. I do not restrict mysel to identical forms or details, ut

What I claim-and desire to secure by Letters Patent is I L/A postcomprising-a concrete body, and

a sheet metal reinforcement comprising a central portion having lateral portions bent substantially as specified.

2. In combination, a concrete post, a vertical sheet metal plate embedded in said concrete'having two bends between its median line and each edge whereby that portion between each two bends is caused to lie against the central portion. on opposite'sides, and the portions between the two outer bends and the edges are extended laterally at right an.- gles to the central ortion, anda series of projections on said s ieet metal plate.

In testimony whereof I have hereunto set Witnesses, this 23 day of March, 1909.
