retreated sept. 5, raie.

Application filed October 2S, 1915. Serial No. 57,556.

To all whom t may concern Be it known that I, BONNER B. Hnosnn, a citizen of the United States, residingat Custer, in the county of Custerand State of South Dakota, have invented certain new and useful Improvements in Fence-Post Molds, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates in general to fence posts and has special reference to a mold which is constructed so as to efficiently and easily form a post by the filling of the metallic mold with concrete and allowing the concrete to become hardened.

Another object of this invention is the construction of a mold .for fence posts which comprises a plurality of hinged sections thereby allowing` the mold to be first filled with concrete and then after the concrete has become hardened, the two sections may be swung to an open position for allowing the post to be removed therefrom.

Another object of this invention is the production of a mold for fence posts which is adapted to allow the green concrete to be poured thereinto, and which is provided with a plurality of corrugated strips and with a rib which are used for molding the forward portions of the fence post, whereby after the post has been removed and is in use the wire may be easily carried thereby.

With these and other objects in view, this invention consists of certain novel co1nbinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed.

In the accompanying drawings: Figure 1 is a. front elevation of the mold shown in position for use and illustrating the same. Fig. 2 is a bottom plan view of the mold. Fig. 3 is a vertical section through the mold. Fig. 1 is a section taken on the line 4-4 of Fig. 1 illustrating the manner in which the two sections are hingedly secured. Fig. 5 is a section taken on the line 5 5 of Fig. 1. Fig. 6 is a fragmentary vertical section through the front portion of the mold taken to one side of the rib used in connection therewith. Fig. 7 is a fragmentary perspective view of the rib. Fig. 8 is a fragmentary detailed perspective view of the means used in locking the forward free portions of the two sections together. Fig. 9 is a detailed perspective View of one of the bottom plates of the mold. Fig. 10 is a fragmentary per-v spective View of the lower end of the corrugated strip. Fig. 1l is a front elevation of a post formedby this mold. Fig. 12 is a fragmentarysectional view through the forward portion of the post illustrating the manner in which the wires are carried thereon. Fig. 13 is a fragmentary transverse section through the forward portion of the post illustrating the same in use. Fig. 14 is a cross-section through the concrete post.

Referring to the accompanying drawings by numerals, it will be seen that the mold as constructed for fence posts comprises a pair of sections 1 and 2. These sections are provided with extending portions 3 which are coiled so as to provide pivot eyes. These eyes are formed in parallel spaced relations relative to each other whereby the eyes of one section niayiit between the eyes of the opposite section, as clearly shown in Fig. 1. The headed rod 4' passes through these eyes so as to retain the same in their correct positions for pivotally holding the two sections in engagement with each other. rThese two sections are adapted to be swung to a closed position when in use, as clearly shown in Fig. 2, so that the coiled tongues 5 of each section may pass into alinement with each other when the two sections are'in a closed position for allowing the key 6 to be carried thereby for holding the two sections against accidentally opening. It will be seen that this key 6 is providedl with a knob 7 at its upper end and with the gripping portion 8 at its lower end, whereby the grip 8 may facilitate the removal of the key. This is accomplished by pulling the key downwardly from the position shown in Fig. 8 until the knob 7 is at the upper tongue 5 at which time the knob may be swung so as to complete one-half of av revolution, Vwhereby it will be allowed to be drawn downwardly past the next tongue which will release the two sections 1 and 2. The third tongue being completely closed holds the key from being entirely withdrawn, and in readiness to be replaced. l

Each section 1 and 2 is provided with inwardly extending ears 9 upon which the plates 10 and 11 are positioned. These plates are provided with apertures 12 through which rivets 13 pass. These rivets 13 also pass through the ears 9 whereby the plates will be secured to the inner ends of the ears 9 as clearly shown in Fig. 3, thereby positively retaining the plates 10 and 11 in their correct positions upon the ears. It will be noted that the plate 10 is provided with an offset fiange 14 which is adapted to fit over the straight edge of the plate 11 as shown in Fig. 2, for forming a tight closure and thus preventing the green concrete from escaping from the lower portions of the mold.

A strip 18 is provided at its lower end with a pair of openings 19 through which the rivets 20 are adapted to pass, for i'ixedly securing the strip within the mold. 1n order to support this strip, however, the rod 4 is provided with brackets 21 pivotally mounted thereon, these brackets being free from engagement with the sections 1 and 2 of the form. The rivets 20, therefore, do not engage the sections 1 and 2 but ixedly secure the strip 18 in engagement with the brackets 21. This strip is split from its upper' end to a point adjacent its lower end so as to provide a longitudinal slot 22, thereby forming a pair of vertical forward portions 23 which are corrugated transversely throughout their entire length as clearly shown in Figs. 3 and 6. This strip 18 is carried at a spaced distance in front of the eyes 3 of the sections 1 and 2, so as to provide suflicient space for the body 24 of the vertical rib. This body 24 has an integral web 25 extending from its forward portions, said web diverging toward its outer end as shown at 26. The brackets 21 are provided with notched portions 27 into which the body 24 of the rib is adapted to rest as clearly shown in Fig. 5. This web 25 of the rib is positioned between the two portions 23 of the strip 18 so as to pass through the vertical slot 22, as shown in Fig. 3, thus allowing it to be drawn from the upper end of the mold or large end of the post. Then this mold is in use it will be closed as shown in Figs. 1 and 2. 1t will be noted that the mold tapers toward its lower portion, which is closed by means of the plates 10 and 11. At this time the strip 18 and the rib will be carried within the interior of the mold. The green concrete may then be passed into the mold so as to fill the same, and any danger of the two sections accidentally swinging to an open position is prevented by the key 6. lVhen the concrete has become hardened, the rib may first be withdrawn from engagement with the mold and post since it extends above the form as shown at 16. Then the key may be drawn as above set forth, at which time the two sections may be swung apart by pivoting upon the rod 4. The post may thenl be easily removed from the mold, at which time 4the construction of the post is completed.

After using this device and the post 28 has been removed, it will be turned so as to allow the thickened end of the post to be its lower end as shown in Fig. 11. It is, of course, obvious that before thev green concrete has been poured into the mold, a plurality of reinforcement bars 29 may be stood within the interior of the mold and be provided with a plurality of transversely extending wire strands coiled around the bars for retaining the same in their correct position upon the mold, as well as providing reinforcements for the concrete post 28 after the same has been formed. 1t will be seen that by the use of the web 25 of the rib, the post 28 will be provided with a slot 31 in its forward portion which is enlarged at the innermost part, as shown at 32. For the entire length of the post this slot extends vertically with and communicating with the transversely corrugated portions 33 formed adjacent thereto, upon the outer face of the post 28. The strands of wire 34 which constitute the strands of the fence, are adapted to be carried upon the side of the post, so as to rest within the selected sections of the corrugated portions 33 whereby the corrugated portions will prevent the accidental movement, either upwardly or downwardly, of the wire strands 34 upon the face of the post 28. The staples 35 are adapted to be carried within the slot and bent with a suitable tool, so as to encircle the wire strands, as clearly shown in Figs. 12 and 13, for holding the same in their correct positions upon the corrugated portions 33 of the post. These staples 35 extend into the rear portions of the slot 31 so that adjacent the enlarged portion 32 of the slot, the staples will be wedged to form nearly a double thickness, as shown at 36 and, therefore, since the slot narrows toward its outer end it will be impossible for the staples to be drawn outwardly toward the forward portions of the slot, since the thickened portion o-f the staples will prevent its passage outwardly. It is, of course, obvious that a suitable tool may be passed downwardly into the slot so as to force the rear portions of the staples apart, whereby they may be drawn through the forward portions of the slot for allowing the wire strands 34 to be removed.

From the foregoing description, it will be seen that a very simple and efficient mold has been provided for constructing cement or concrete posts, into which the green cement or concrete is poured so as to allow the same to set therein, at which time corrugations will be formed thereon, together with the formation of an internal slot which will facilitate the attaching of the wire to the posts when the same is in use.

lVhat is claimed is:

1. In a mold of the class described, the combination of a pair of sections having parallel spaced eyes, the eyes of one section being adapted to lit between the eyes of the other section, a rod passing through said eyes for hingedly retaining said sections in engagement with each other, means for closing the lower portion of said sections, the
