FENCE-POST MOLD.

Specification of Letters Patent.

Patented April 27, ieoe.

Application filed October 15, 1907. Serial No.'397,551.

To all whom it may concern:

Be it known that I, CLINTON B. BRUNER, a citizen of the United States, residing at Princeton, in the county of Gibson and State of Indiana, have invented new and useful Improvements in Fence-Post Molds, of which the following is a specification.

The invention relates generally to an improvementin molds, and particularly to a portable'fence post mold constructed to permit the convenient molding of the post at the place of use.

The main object of the present invention is the provision of a fence post mold comprising a single split section of material, the inherent resiliency of which is such as to normallymaintain the edges of the section in spaced relation, the construction including a c amping means whereby the edges of the section may be forced into contact to maintain the section in molding condition.

A further object of the invention is the provision of means for guiding the edges of the section during the movement of the clamping rings to thereby insure alinement of the section edges and a smooth molded article, and the formation of notches at appropriate points throughout the length of one of the edges of the section to permit the introduction of fasteningor supporting members designed for permanent attachment to the 0st.

T e invention will be described in the following specification, reference being had particularly to the accompanying drawings, in which Figure 1 is a view in elevation, illustrating my improved post mold in position to ermit the introduction of the plastic materia Fig. 2 is a vertical central section, partly in elevation, of the 0st formed in the use of my improved mod. Fig. 3 is a broken vertical section of the mold, showing the'same supported upon. the previously formed base ortion of the post. Fig. 4 is an elevation o the mold with the edges of the section in normal relation, a mold extension being illustrated. Fig. 5 is an elevation of the post showing a slightly modified form of base. section on line 6-6 of Fig. 5.

Referring particularly tothe drawlngs, my improved fence post mold comprises a body or shell 1 of cylindrical form in cross section and longitudinally tapering from the lower toward the upper end. The shell is longitu- Fig. 6 is a dinally divided throughout its length to provide edges 2 and 3, and the inherent resiliency of the shell is such as to normally maintain these edges in spaced relation, as shown in Fig. 4.

In conjunction with the shell I use clamping rings 4, of such diameter as to fit the shell at different points in the len th of the latter when said shell is in norma condition, the rings being adapted to be driven lengthwise on the shell to force the edges 2 and. 3 into contact, the frictional engagement of the rings with the shell serving to maintain said edges'in contact until the rings are driven in the reverse direction. are also each provided with guide fingers 5, each of which is" designed to at all times overlie and rest upon that edge of the shell opposing the edge to which it is connected. These fingers serve to guide the edges of the shell in their movementunder the influence of the clamping rings, thereby insuring pro )er alinement of the inner surface of the iell at the edges and )ermitting the molding of a smooth post. v ne of the edges of the shell, 3, is formed at appropriate intervals with a series of indentations or recesses 6, for a purpose which will presently appear.

In use the post 'hole, as 7, is filled with a cement body 8, in which is embedded an upright'Q, either in the form of a rod or pipe section, said upright being centrally enibedded in the body 8, which forms the base of the post, and projecting above said body approximately equ'al to the length of the desired post. The mold is then closed. by the described operation of the rings 4, and disposed ,upon the base 8 with the upright 9 in the center of the mold. The plastic ma- The edges of the shell trial is then introduced into the mold, as by afunnel 10, and after suitable tamping, if such is necessary, may be allowed to harden. After the initial filling operation the fastening means, as staples 11, are passed through the recesses 6 in'the edge of the mold section and firmly seat in the plastic material,

tion of the particular-means used. After the proper setting'of the plastic material forming the post, the rings 4 are driven in the upward direction, freeing their clamping engagement with the shell and permitting inherent resiliency of the latter to a ain spread the edges 2 and 3. This material y increases the,diamother, said wingshaving their outer edges inclined upward y'and inwardly relative to the base proper, as shown 11'!- Fig. 5. These wings render the base more resisting in the event of strain and are particularly designed for use with those posts forming gate supporting members, in which event the wings will be arranged with 1particular regard tothe strain exerted by t of the gate.

In utilization of the mold for forming gate posts it is, of course, to be understood that at appropriate points in the shell recessesfi will be formed to receive the post member of the hinge connection for the ate, so that said members may be embedded in the post during the process of molding the latter;

A's the mold is designed for forming the post at the place of use, it is obvious that owing to the generally uneven nature of the ground that, without special provision there.- for,'the osts will not terminate on the same level. n o avoid this objection I contemplate the use of an extension 13 in connection with the mold proper, which extension-comprises a cylindrical shell secured to and forming a ractical continuation of the main mold sell, the extension shell being longie additional weight tudinally divided to register with the divi sion of the main mold shell and being. also provided with a clampinglring 14 adapted to operate the extension s ell similar to the rings 4 in connection with the main shell.

Furthermore, the main shell may be pro vided with a hook and

eye connection

15 and 16 secured adjacent the respective edges of the shell with the parts so arranged that when said edges are brought into contact under the influence of the clamping rings,

the hook members 15 may be engaged with the eyes 16 to secure the shell in such position. Accidental separation of the edges during the molding operation, through movement of the clamping rings is thus prevented,

proper and I contemplate the use of the hooks either with or without the clam ing rmg.

i The upright 9 forms a materia part of the present invention as it provides an effective means or centering the post proper with relation to the base, and at the same tune so connects the post to thebase as toinsure practically an integral structure. As the mold is simply designed to support and sha e the plastic material or the 0st during t 'e .molding operation, it is obvious that it may be constructed of comparatively light material and may be readily trans-- ported from place to place as necessary. Furthermore,'the mold proper comprises in effect but three parts, the shell and the two clamping rings, and as these rings may remain at all times on the post my improvement necessitates in elfect the transportation of but a single article so far as the mold is concerned.

Having thus described the invention what is claimed as new, is

A 0st inoldcornprising a shell longitudina y divided throughout its length, the inherent resiliency of the shell normally maintaining the edges of the division in spaced relation, one of the ed es of the material forming the shell being ormed with a series of recesses opening through the edge, the remaining edge of said material being adapted to c lose the mouths of said recesses when the shell is in closed relation, a series of independent guide fingers arranged in pairs and carried res ectively by the opposing edges of,the shell: said fingers being of a length toengage-both edges of the shell when said edges are in spaced relation, 'clamping rings adapted to cooperate with the shell to force the edges thereof together, an extension encircling the lower edge of and secured to the shell, said extension be' g longitudinally divided to register with he division in the shell, a clamping ring for the extension and cooperating latch members and adapted when in latching position to maintain the shell and extension closed i11- dependent of the clamping ring.

In testimony whereof I aflix my signature in presence of two witnesses.
