sPECIFICATIoN forming part of Lettere Patent No. 768,112, dated August 23, 1904.

Application filed March 28, 1904.

To ttl?, whom, it mayy concern:

' Beit known that we, CLARENCE L. CATHER- MAN and JOHN H. CATHERMAN, citizens of the United States, residing in Porter township, in the county of Cass and State of Michigan, have invented certainnew and useful Improvements in Cement Posts, of which the following is a specification, reference being had therein to the accompanying drawings;

Our invention relates to Vimprovements in fence-posts or other columns made of cement, concrete, or the like, one of the objects being to provide a post of the class described Wherein simplicity and inexpensiveness of construction shall be combined withdurability and strength.

Afurther object of the inventionris to provide a post that shall have special reinforcements at the point where the most strain is usually encountered in cement posts lor columns, and that is where the most resistance and tension is caused by the action of the frost in the soil where, the post or column may be embedded.

Afurther object of our said invention is to provide for the use of barbed wire of the sort commonly known to commerce as a reinforcing power7 in the manufactureof plastic posts, and still another object is to `provide improved means for securing wire fencing to such posts. 1

The invention consists inthe novel features and details of construction which will be hereinafter more fully set forth, illustrated, and finally claimed.

In the drawings accompanying this specificationand made a part hereof, Figure l is a perspective view of the post, showing the set of short cables-embedded therein. Fig. 2 is a detail view of one of the short cables. Fig. 3k is an elevation of the post, showing a portion of the runner-wires. Fig. 4 is a horizontalv section.

In the drawings similar letters of reference designate corresponding parts throughout the several views.

A designates'the body portion of a-post or serial No. 200,451. (No model.)

column made of any plastic material, such as cement, concrete,V and the like.

B is a single strand of wire bent on itself in the form of an inverted U .and having at its lower ends projecting prongs or anchors o'. This strand of wire is also provided with a plurality of barbs b, disposed at any suitable distance apart, being preferably equidistant from each other. These barbs are preferable to all other forms for the purpose of lending tensile'strength to the post; A pluralityT of these sections of barbed-wire strands B are placed in the post while the same is in its plastic state and there allowed to remain in position until `the material of whichv the post is made is permitted to harden for use. As many of the strands B may be placed in the post as are found desirable.

As a special means of lendingstrength and durability to this class of posts frost-resisters C are formed of short pieces or strands of y wire bent at right angles at the ends thereof, thus forming prongs or anchors c. These strands or piecesof wire are also embedded in the post while its material is yet in a plastic state-at a point where they will reinforce the same at the soil-line. It will at once be observed that any desirable number of these frost-resisters may be used and that they may be disposed at any suitable relation to each other.

D designates a preferred form of staple to be embedded in the post at suitable distances from each other. These staples are formed of asingle strand of wire or other suitable material bent on itself inthe shape of a U, then bent back again in the form of hooks at each end, as shown. These staples may be placed in the post, as shown in Fig. 4, leaving an extended loop d. This form of staple is found to be preferable to any other on acjcount of its simplicity of construction and the furtherreas0n that it cannot possibly be pulled from the post without breaking the post. However, different modifications of form will suggest themselves to' theskilled mecl1anic,and we do not, therefore,desire to be limited to the precise construction shown. These staples may be arranged in the post, as shown in Fig. 3, the runner-wires E passing above a single staple, as shown at e, and a locking-rod F, passing through the projecting loop Z to hold the runner-wires in place, or two of the staples may be embedded close to eaeh other, as shown at f, leaving only sut'- ticient space for the runner-wires E to pass between them and the lockingrod, which passes through the extending loops CZ, as above described.

As a further means of lending tensile strength to this post a single strand of wire G, having a plurality of barbs g thereon, arranged at frequent intervals and preferably equidistant from each other, may be placed in the center of the post, as shown.

While the reinforcing means herein shown and described are shown and described as applicable to fenceposts, it is obvious that our invention can be applied to mile-posts, corner stones, telegraph poles, building columns, or similar articles. lt is also obvious that the shape of the post or column is immaterial, since our invention can be applied to posts or columns of any geometrical ligure or form desired.

Having thus described our said invention, what we claim as new, and desire to secure by Letters Patent of the United States, isn

l. A composition fence-post having' reinforcing-cables embedded therein near the outer corners, each extending longitudinally thereof for approximately the full length of the post, laterally-extending anchors secured yto the cables at intervals, another set or' shorter cables embedded in the post within the area inclosed by the lirst set and extendingl longitudinally l'rom a point below to a wardlyat its end parallel to the side tace ol:

the post to constitute anchors, barbs secured to the cables at intervals, and another set oi shorter cables embedded in the post at the side oi the center and within the area inclosed by the first set and extending longitudinally from a point below to a point above the ground-line oi' the post.

3. A composition tence-post'y having reinforcing-cables embedded therein near the outer corners, each consisting olE barbed wire with the ends bent inwardly to constitute anchors, another cable extending longitiulinally oi the central axis ot' the post and provided with barbs, and a third set ol shorter cables of barbed wire having inturned ends and arranged longitudinally in the post within the area inclosed by the lirst set, the lirst two sets of cables extending for approximately the full length ot the post and the third set extending from a position below to a point above the ground-line.

In testimony whereof we hereunto allix our signatures in presence of two witnesses.
