FENCE-POST MOLD.

Specification of Letters Patent.

Patented Oct. 9., 1906.

Application filed February 17, 1906. Serial No. 301,706.

To and whom it may concern.-

Be it known that I, WILLIAM REID GOL- LIER, a citizen of the United States, residing at Beaumont, in the county of Jefferson and State of Texas, have invented a new and useful Fence-Post Mold, of which the following is a specification.

This invention relates to molds, and is particularly designed for forming artificial fenceposts. In this connection it is proposed to provide for conveniently setting strandwires longitudinally within the mold so as to have the same embedded in the post, and thereby stiffen and strengthen the latter.

Other objects of the invention are to enable the convenient filling of the mold, to facilitate the piercing of the post before the material becomes set for the introduction of fence-wire-fastening devices, to permit the introduction of water into the mold, so as to have the material immersed and thereby facilitate the hardening thereof, to provide for forming the posts in pairs and to enable the production of any number of pairs of posts in longitudinal alinement, and to prevent connection of the posts at their ends, so as to leave the wires exposed for cutting prior to removing the posts from the mold.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood thatchanges in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of theinvention.

In the drawings, Figure 1 is a perspective view of a mold embodying the features of the present invention, the core member being shown above the mold in position for entering the same. Fig. 2 is an enlarged crosssectional view of the mold with the core in position. Fig. 3- is a similar view showing the core removed and water contained in the mold. Fig. 4 is a cross-sectional view taken between adjacent moldsections. Fig. 5 is a side view of one of the brackets for the support of one of the strand-wires. Fig. 6 is a detail perspective view of a slide for one of the brackets.

Like characters of reference designate corresponding parts in all of the figures of the drawings.

and the side 3,

The present mold includes a base 1, supported upon sills 2, stood on edge and located inwardly from opposite edges of the base. Rising from opposite longitudinal edges of the base are the sides 3 of the mold, each of which is substantially one-half as wide as the base 1. 1 An upstanding partition 4 is placed upon the top of the base midway between its longitudinal edges, whereby the body of the mold'is divided into two longitudinal compartments, each of which is designed to form a post.

The rectangular core member 5 is designed to be placed downwardly through the open top of the mold and supported upon the partition 4 midway between the opposite sides 3 of the body of the mold, thereby to define cast compartments which are substantially L shape in cross section to produce an angleost.

p Each longitudinal section of the mold is provided with a top 6, which is hinged to the adjacent side 3 by suitable hinges 7, whereby said top members may be swung open, so as to give access to the space between the core the width of the top being such as to fit snugly the adjacent side of the core when the parts are assembled.

- At suitable intervals throughout the length of each compartment triangular corner-blocks 8 are fitted in the internal angle between the bottom and the adjacent side of the mold, so as to produce transverse notches in the outer longitudinal corner of the post. Openings 9 and 10 are formed, respectively, through each side of the bottom of the mold at the ends of each block 8, said openings converging inwardly. I

At each end of the mold the space between the box and the core is closed by a pair of substantially L-shaped end plates 19, which have the inner ends of their horizontal members abutted. The core is of course longer than the box in order that it may be embraced bythe upright members of the end plates, so as to hold the core centered within the box when the top members 6 are open during the filling of the mold-box.

With a mold constructed as thus far described posts may be formed by introducing plastic molding material into each compartment of the mold to the top of the partition 4, whereupon the core 5 is introduced and additional molding material placed between the core and the sides of the mold, after which the tops 6 are swung down so as to press the material within all of the corners of the moldcompartments. Before the material has become set suitable cutting-tubes are thrust through the openings 9 and 10, so as to produce openings through the post at opposite sides of its external longitudinal edge. Substantially U-shaped wires 11 (shown in Fig. 3) are then thrust through the openings in the post and the body portion of themold from the interior of the posts, the wires being of a length to project externally of the posts for a length sufficient to permit the same being twisted around fence-wires, so as to connect the latter and the posts. The open ends of the mold are then closed by means of plastic material, such as clay, and the mold is then filled with water, as indicated in Fig. 3, so as to have the posts immersed, and thereby to facilitate the hardening or setting thereof. To release the post from the mold, the top members 6 are swung open and the mold inverted and then lifted from the cast.

It is proposed to stiffen and strengthen each post by means of strand-wires, such as shown at 12, there being one wire in each member of the post and another wire through the middle of the post. These wires are placed in position prior to filling the mold and are stretched in the manner indicated in Figs. 1 and 5. For the support of each wire a bracket 13 is provided upon each end of the base 1, which projects at opposite ends of the mold, said bracket being braced by suitable braces 14 and 15. Upon the standard formed by the upright member of each bracket there is a slide 16, which is sub stantially semitubular in form and provided at its opposite edges with inturned flanges 17 to engage the back of the standard with the front of the slide spaced in front of the standard and provided with an opening 18, through whichthe adjacent wire is passed. By preference each wire is made up of twisted strands, the strands being separated and brought forwardly across the top and bottom of the slide and then twisted upon the wire, so as to connect the latter to the slide, as slearly shown in .Fig. 1 of the drawe ings. A suitable implement is then introduced between the strands of the wire and manipulated to twist the wire until it has been tightened, whereupon the slides at the opposite ends of the wire are forced downwardly until the wire occupies the desired position in the mold. By preference the back of the standard 13 is inclined downor more moldsin longitudinal alinement, the substantially L-shaped end plates 19 are insertedfrom opposite sides of the mold between'the adjacent open ends of successive molds, the horizontal member of each plate having a bifurcation'20 to receive the adjacent lower wires, while the upright portion of the plate has a transverse notch 21 to receive the upper wire, the inner ends of the spacing-plates being abutted and of a width to close the space between the molds which bound the wire member. After the posts have become set the spacing-plates are driven out, so as to expose the wires between the molds to enable severing of the wires at this point preparatory to removing the casts from the molds.

It is proposed to have the mold shaped so as to give the cast an upward taper from that portion of the cast which is designed to be located substantially flush with the surface of the ground.

Having thus described the invention,'what is claimed is I 1. A mold comprising amold-box'which is open at its top, a longitudinal partition rising from the bottom of the box and terminating short of the top thereof," and a removable core of less width than the bOX' supported upon the partition.
