BEINF JRCEWIENT FOR CEMENT CONSTRUCTIQNS.

. omit may (seem: c it that l, ALEXANDER FLEMiNG,

- a citizen, of the United States, residing at Cedar Rapids, in the county of Linn and State of Iowa,laave invented certain new and useful improvements in Reintorcemen-ts for Cement Constructions; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to reinforcements for cement constructions, and is more particularly adapted for the completion of fence posts or other structures capable of withstanding the rough usage to which the same are necessarily subjected.

The present application embodies an improved construction on my former application for patent for a similar invention filed Aug. 6, 1911, Serial No. 576,017, whereby the general construction of the postis improved by the em-ploymentot truss wires enveloping the entire structure and having their ends interlockingly engaged with the of the bars forming a part of the structure for the purpose hereinafter described.

The primary object of the invention is theretora'in the formation of a metallic skeleton frame or structure which is light,

' durable and efiective for the purpose, the

parts being bindingly and properly assem-v in such a manner that when the cement is combined therewith in the final completion of the post, or stru cture, a perfeet and uniform construction is produced. Briefly stated the invention consists in the employment of angle bars which are uniformly connected in their proper position in 'respect to one another by binding bands pr operly positioned along the length of the bel s and connected to one another, and

crossing and separately arranged truss wires I extending from the opposite ends of the frame and bindingly in contact with the outer edges of said bars and also in contact with the bands, the opposite upper and lower ends of said bars being notched at their medial portions to receive the opposite connected en s of the truss wires, the lower ends of the l tter projecting inwardly and having upwardly projecting hooks forming yielding anchors which are embedded in the cement during the final completion of the t -With these and other objects in View, the

Specification of Letters Patent.

Applicafion filed September 7, 1911.

Patented July 1912.

Serial No. 648,235.

invention consists of certain novel features of construction, and the combination and arrangement of parts as will be more fully tion of the lower end of the structure; and,

Fig. 4 is a perspective view showing one of the angle bars employed in carrying out the invention. 1

In the illustrative embodiment of the invention, 1 represents a series or plurality of angle bars which are preferably three in number and angularly positioned in respect to one another for properly and uniformly constructing the post for the purpose hereinafter described. The post when completed is preferably triangular in cross section, the bars of which the same is composed being connected and properly spaced in respect to one another by a series of bands, 2 and 3, arranged in' pairs and engaging with the inner and outer surface of the bars at predetermined distances along the length of said bars, the bands thus arranged being.

connected and bindingly brought into engagement with the bars by clips 4 which are folded around the bands thus arranged,

' all of which isclearly shown in Fig. 1 of the drawing. The opposite upper and lower .ends of the bars 1 are inclined as shown at 5, forming notches 6 at the medial portions thereof for the purposes now to be de-- scribed.

' The truss wires 7 employed in carrying out the construction of the frame embody an essential part of the construction as will be observed, and extend throughout the length of the frame and are diagonally arranged in respect to the bars 1- and are crossed in such a manner as to cause their connected portions to overlap at the outer edges of the bars as clearly shown. The free ends of the truss wires 7 are bent over and brought into engagement with the notched upper and lower ends of the bars 1, whereby the said truss wires closely embrace and contact with the structure previously described. As clearly shown in Fig. 3 the lower ends of the truss wires 7 are formed upwardly after engaging with the lower notched ends of the bars and are exl 8 are formed and are provided with downwardly projecting pointed hooks 9 which.

are embedded in the cement during the complete formation of the post. The meeting and connected ends of the truss wires 7 at the opposite ends of the structure are similarly formed whereby the anchors referred to. are arranged in a practical manner for the purposes described, and further it will be observed that the parts comprising said structure are uniformly and. bindingly arranged with respect to one another. The truss wires 7 not only retain the complete formation of the post but further hold the binding bands in their proper position upon the angle bars 1, whereby the same are properly positioned. i

From the foregoing description takenin connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the invention defined and claimed. Having thus described my invention, what I claim as new is: a g

1. A reinforcing frame comprising a pini-ality of bars, means for connecting the bars and properly separating the same in respect to one another, and diagonally arranged truss wires spirally arranged on the outside of said bars and bindingly in contact there with, and having their ends interlockingly 50 bars, the lower ends of the two wires being extended inwardly and upwardly and provided with downwardly projecting anchors.

length of the bars for uniting the same and properly positioning the same in respect to one another, means for connecting said bands and binding the same against the bars, diagonally arranged truss wires extending the full length of the bars and over lapping and bindingly engaged with the bands, notches formed in the beveled ends of the bars with which the opposite ends of the truss wires are bindingly and interlockingly engaged, the lower ends of said truss wires being extended upwardly and in wardly and provided with downwardly projecting hooked ends-forming yielding anchors for engagement with the cement employed in the final completion of the structure.

4. A reinforcing frame for cement constructions, comprising a plurality of angle bars having upper and lower beveled ends, binding bands arranged in pairs and posi-' tioned at predetermined distances along the length of the bars foruniting the same and properly positioning the same in respect to one another, means .for connecting said bands and binding the same against the bars diagonally arranged truss wires extending the full length of the bars and overlapping and bindingly engaged with the bands, the ends of said two wires being arrangedin the notches formed in the beveled ends of the bars, and anchors formed by the-lower connected ends ofthe truss wires and inwardly projected and adapted to engage with the cement completing the structure.

In testimony whereof I have hereuntoset my hand in presence of two subscribing witnesses.

ALEXANDER FLEMING.
