Specification of Letters Patent.

Patented Oct. 23, 1906.

To a/ZZ 14x/1,0m,V it may concern:

Be it known that I; FRANCIS M. WHITE, a citizen of the United States, residing at Newkirk, in the county of Kay and Territory of Oklahoma, have invented a new and useful Mold, of which the following is a specification.

This invention relates yto molds, and is particularly designed for the formation of concrete and other artificial fence-posts and to provide an arrangement whereby a plural'- ity of posts may be cast within a minimum of space.

It is furthermore designed to facilitate the setting up of the mold and also the taking apart thereof in order that the mold maybe `readil removed from the posts before they have ecome entirely set, whereby the mold may be again set up and iilled with material before the original set of posts have become hardened.`

With these and other objects in view 4the I present invention consists in the combination and arrangement of parts, as --will be hereinafter more fully described, shown in the accompanying drawin s, and particularlypointed out in the appen ed claim, it being understood that changes in the form, proportion',

i f size, and minor detailsmay be made within the scope of the claim without departing from lthe spirit or sacrificing any of the advantages l,0f-'the invention.

'In the drawings, Fi e 1 is a plan view showing a series of mol s set up in accordance with thepresent invention. Fig. v2 is a crosssectional view taken on the line 2 2 of` Fig. 1. Fig. 3 is a crosssectional view taken on the line 3 3 of Fig. 1. Fig. 4 is a fragmentary perspective view of one end of themold. Fig. .5 is a detail perspective view of one of the sides of the mold.

Like characters of reference designate corresponding parts in all of the figures of the drawin s. f

For t e support of the sides and ends of the present mol there is provided a bed or base 1, preferably of concrete or the like, having a width substantially equal to that of the length of the mold. Upon this base at each edge thereof is placed a head-bar 2, which is provided throughout its inner face with a plurality of pairs of upright open-ended kerfs or seats 3, the distance between ad'acent pairs of seats being greater than the distance between the members of each pair. Extending between the head-bars 2 isa series of the inner end ortions of the strips overlap.

sides 4, each of which is in the nature of a board or plate stood on edge with its opposite ends in corresponding seats or notches of the oppositehead-bars. When a suitableA number of side bars have thus been assembled, wedges 5 are driven in between the outer faces of the head-bars and stakes 6, which are driven into the ground at o posite sides of the base or bed, whereby tlpie side bars are snugly embraced between the headbars. The spaces bounded by the side b ars and the head-bars are then lled with plastic material and permitted to stand until it becomes set suiiiciently to enable the removal ofthe head-bars and side bars Without injuring the casts, which may be done before the posts have become thoroughly set, whereby the mold may be reassembled and again filled Without waiting for the original posts` to become entirely set. l ,[t will here be noted that with the exception of the opposite terminal sides each sidebar formsone side of two ad`acent mold-boxes, whereby a .plurality o mold-boxes may be set up in a minimum of space.

To remove themold-boxesfrom the casts,

tween the casts, leaving-the green posts to harden, while the mold-boxes may be again assembled in Aanother place without waiting for the posts to become entirel set.

.When it is ldesired to have eveled edges upon the posts, each side bar or plate has a to one face o the bottom of the side with one end terminating short of one end of the side bar and its other end extending slightly beyond the middle of the bar. Upon'the other side of the bar there is another similar stri 8, vwhich terminates short of theother cndp of the. bar and extends a suitable dis'- tance beyond the middle thereof, lwhereby When a moldox is set up, the strip 7 of one side and the strip 8 of theother side lie within the mold-box and form' beveled edges upon the cast throughout the upper sma ler portion thereof. v

Itis pro osed to provide the side bars 4 with aline perforationsv 9, through which wires 10 are passed, said wires belng Withdrawn from the mold prior to taking the triangular stri 7 nailed or otherwise secured latter apart and being employed for the vpur- 11o pos-e of forming openings through the posts l for the reception of fence-wires or fence-wire fastenings.

Each post may be materially stiiened by means of a wire 1 1, supported upon the wires 10 so as to be held in place when iilling the molds. An intermediate portion of the stiffening-wire is bent back and forth, as shown in Fig. 1, so'as to provide a plurality of wire strands extending a suitable distance above and below that portion of the post which is to be located at the surface of the ground, thereby to stiften the post where the greatest amount of strain is applied.

. Havi-n thus described the invention, what is claime is l A mold comprising a base, oppositely-disposed bars constituting end walls and having their inner faces provided with a plurality of pairs of vertically-disposed kerfs, the dis'- tance between adjacent pairs of kerfs being greater than the distance between the kerfs of each pair, converging side bars seated `jacent end bar, rods dispose within corresponding and each provided with a plurality of spaced transverse perforations disposed adjacent the upper longitudinal edge thereof, beveled strips secured to the opposite faces of the side bars at the lower longitudinal edges of said bars and having their inner ends overlapped and spaced from one of the end bars an their outer ends bearin against the adc? parallel with the end bars and threaded through the perforation in the side bars, abutments spaced from the end bars, and wedgefshaped blocks inter- Vposed between the abutmen-ts and the adjacent end bars for locking the side bars within the kerfs.

In testimony that I claim the foregoing asl my own :[.have hereto affixed my signature in the presence of two witnesses.
