FENCE-POST MOLD.

Specification of Letters Patent.

Patented July 20, 1915.

To all whom it may concern:

Be it known that I, MELVIN Bmmrs, a

citizen of the United States, residing at lendon, in the county of Mercer and State of Ohio, have invented certain new. and useful Improvements in F once-Post Molds, of which the following is a specification, reference being had to the accompanying drawings. r

My invention relates to molds for forming articles from concrete or like artificial stone, and particularly to molds for forming the intermediate and corner posts of fences.

The main object of my invention is the provision of a very simple mold forforming a concrete fence post so constructed as to form' an integral brace on the post extending either in one or twodirections from the post.

A further object is to provide a mold of this character which shall be simple in construction and formed of sections so connected as to be readily taken apart and put together. 1

Still another object of the invention is to provide a mold which is adapted to rest upon the ground and to form theupper part of a fence post, the lower part having been already formed by pouring concrete into a suitable trench out into the ground,

Still another'object of the invention is to provide means whereby the interior strips used for forming the inner walls of the mold shall be readily removed when the mold is taken apart.

Still another object of the invention is to so construct the mold that the sections may be taken apart without the necessity of hammering the bolts holding the sections together or disloclging the mold strips by force so as to prevent any chance of breaking the concrete forming the post.

Other objects will appear in the course of the following description.

My invention is. illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation of one form of my fence post; Fig.2.is a perspective view of another form ofpost; Fig. 3 is aside elevation of the mold used for the form of post shown in ig. 1; Fig. fl is a vertical section through the post shown in Fig. 1 with the mold in place; Fig. 5- is a section on the line 5-5 of Fig. 3; Fig. 6 is a section on the line 66 of Fig. 4; Fig. 7 is a section on the line 7 7'of Fig. 4; Figsi 8 and 9 are perspective views of the cover plates; Fig. 10 is a horizontal section taken through the mold used for forming the fence shown in Fig. 2.

Corresponding and like parts are referred to in the following description and designated in all parts. of the accompanying drawings by like reference numerals.

These figures illustrate a concrete fence post, Fig. 1 illustrating one of the intermediate posts of the fence, and Fig. 2 one of the corner posts of the fence. It will be seen that each post comprises an upwardly extending shaft a-whose lower end is sunk sufficiently deeply into the ground, and which extends above the ground, and formed integralwith the post a is a brace 72 or a plurality ofthese braces, as in Fig. 2, that extend downward and outward a suitable distance from the base a, and connected to the base a by a transverse member 0 resting on the ground and preferably disposed in a trench formed in the ground. The lower portion ct of the post and the member'c are first formed by cutting a suitable vertical hole in the ground from which extends a trench disposed at the ground level. The concrete is then poured in this L-shaped recess in the ground so formed, and afterward the upper portion of the post is formed upon the basic portion by means of the mold which will be hereinafter described. The only difference between the form shown in Fig. 1 and that shown in Fig. 2 is that in the latter two braces b are used and two connecting members 0.

As before stated, the mold is adapted to be set upon the ground on each side of the connecting member 0 and while the concrete or. artificial stone of this connecting'member is still soft, and to this end the mold consists of two sections. Where the fence post shown in Fig. 1 is to be formed, each section is triangular in general form and consists of a plate 2 of relatively thin sheet metal. The rear portion of this plate forming the vertical side of the triangle is curved as at?) to constitute the curvature of the post 0;. The base of the triangular plate 2 is provided with outwardly extending feet 4 and 4 which are formed of angular strips riveted to the plate 2. The upper portion of the strip forming the foot 4 is outwardly bent as at 5 and extends above the upper edge of the mold plate 2, and is longitudinally slotted as at 6. Attached to the upper margin of the plate 2 adjacent the curved portion 3 and projecting above the upper edge of the plate 2 is an ear 7 which above the rivet 8 is slightly deflected, the upper end extending above the upper edge of the plate 2 and being formed with the longitudinal slot 9 extending in the same direction as the slot 6. Midway between the upper ends of the members 4 and 7 is disposed an outwardly projecting ear 10 formed by riveting an angular piece of metal to the upper margin of the plate 2. In order to form the fence post shown in Fig. 1 there are two of these plates 2, both exactly alike in construction and spaced from each other a distance equal to the thickness of the brace 79 and the portion 0 of the post. To this end the plates are spaced from each other by spacing sleeves, and held in this spaced relation by means of transverse posts. As illustrated, the plate 2 is formed with three bolt holes 11 extending approximately in line with the upper edge of the plate. Two more bolt holes are provided, designated 12, one being disposed adjacent the lower edge of the plate and adjacent the curved portion 3, and the other is disposed intermediate the lower bolt hole and the upper edge of the plate. Spaced sleeves 13 are used to separate the plates, as before stated, through these spacing sleeves, which are preferably three-fourths of an inch in diameter in a full sized mold, pass the half inch bolts 14. The reason for using half inch bolts in three-fourths inch sleeves is to permit the bolts to be readily withdrawn so that there will be no necessity of hammering the bolts and thereby possibly breaking or marring the fence post.

Disposed between the plates are strips 15 16 and 16. The strip 16 rests upon the top of the concrete member 0 previously formed, while the strip 15 extends upward and inward at an inclination to the strip 16 so as to form one face of the brace b. In order to permit the strip 15 to be readily removed from its position immediately beneath the brace b and between the connecting portion 0 and the base portion a, I preferably form the strip in two sections, these sections having inclined abutting faces as at 17. By making the strip in two-sections the strip will fall from its position as soon as the side pieces of the mold are removed from engagement with the fence post and there will be no necessity of hammering the strip 15 out of its position. These strips 15 16 and 16 are simply held in place by engagement with the walls of the mold, but the strip 15 also rests upon the bolts passing through the bolt holes 11 so as to support the weight of the liquid concrete or grouting forming the brace Z).

Inasmuch as liquid grouting or concrete is poured into the mold, it is necessary to side flanges of the section 19 at their lower ends are also longitudinally slotted as at 21,

while the upper end of the section is mitered. When these sections are placed in position between the mold plates the ears 10 will enter the

slots

20 and 21, the side flanges of the covering members 18 and19 extending down over the upper margins of the plates 2, and these covering members will be held in position by transverse detachable strips 22 which are engageable in the

slots

6 and 9, respectively.

The curved portions 3 of the mold plates are formed with a plurality of openings for the passage of transverse bolts, these openings in each plate beingarranged in staggered relation. The perforations 23 are nearly one-half inch in diameter in the actual embodiment of my invention, and are for the purpose of forming openings through the fence post for permitting the attachment of the iron pipe or iron rod forming the end of the fence panel. The opening 24 is for a gate fastener, while the openings 25 disposed aboveand below the opening 24 are for the attachment of the gate hinges. These

openings

24 and 25 are preferably nearly three-fourths of an inch in diameter. Then the mold sections are arranged in proper relation to each other bolts 26 pass-through the

openings

23, 24 and 25, and surrounding these'bolts are the sleeves 27 these sleeves being three-fourths of an inch in diameter for the

openings

24 and 25, and preferably one-half inch in diameter for the openings 23. It will be noted that thenbolts passing through the openings 23 are disposed at an angle to the bolts passing through the

openings

24 and 25, so that these two sets of bolts cross each other.

With this form of mold, the lower portion of the fence post, that is, the portions 65 and c, are first formed as previously described, and preferably reinforced, the reinforcing rods of the portion a extending up from the ground. The mold sections are then assembled so that the curved portions 3 surrounding the reinforcing rods extend upward from the portion a and the mold is ready for use. The concrete or other composition in a relatively liquid state is now poured into the mold filling up the portion of the mold defined by the curved portions 3 and also filling up that portion of the mold between the strips 15 and the

cover portions

18 and 19; After theconcrete is set, which actual experience has shown me is in about twentyfour hours, the bolts holding the mold sections to each other are unloosened and removed. The, covers 18 and 19 are taken off and the mold sections spread apart, and as before stated, the strip 15 will fall downward because it is made in two sections with the angular joint 17. The section l6isrelatively short and may be readily removed.

The form of mold shown in Fig. 10 is formed of precisely the same parts as that shown in Fig. 6, the only difierence being that the plates are angular in plan so. as to form braces extending in two directions from the post. Thus the plate 2, which corresponds to the plate 2', is simply angular in cross section, while the plates 2, which form the outer faces of the braces are connected by a circular portion 3 through which passes the bolts which are designed to pass through the sleeves intended to be permanently formed in the post itself. Otherwise, the mold shown in Fig. 10 is precisely the same as the mold shown in Fig. 6 and is supported in the same manner and used in the same way.

It will be seen that my invention is very simple, has very few parts, is cheaply made, and that it is thoroughly effective in practice for the purpose intended.
