CONCRETE-FENGE-POST MOLD.

Specification of Letters Patent.

Application filed. April 27, 1912.

To all whom it may concern:

Be it known that I, Gos'rnv H. Fnnsun, a citizen of the United States, residing at Clark, in the county of Randolph and State of Missouri, have invented new and useful Improvements in Concrete Fence Post Molds, of which the following is a specification.

This invention relates to concrete fence post molds and has for an object to provide a mold of this character which will consist of a plurality of mold sections and means for uniformly holding the sections colleclively or detachably connected together in set up positions.

Another object of the invention is to provide a mold which can be constructed of substantially identical sections.

A still further object of the invention is to provide a mold which will be strong and durable in construction, eflicient for the purpose intended and inexpensive to manufacture.

In the drawing forming a portion of this application, and in which like letters of reference indicate similar parts in the several views: Figure l is a perspective view of the mold showing the same set up. Fi 2 is a perspective view of one of the sections. Fig. 3 is a perspective view of another section of the mold. Fig. 4 is a horizontal section taken on line d-t of Fig. 1.

The mold is preferably constructed of heavy sheet metal and it is shown to include substantially identical sections 1 and 2, the latter being adapted to lit in the former and being coextensive in length therewith. Each section is provided with walls 4-, 5 and 6, the walls 5 and 6 of the section 2 being adapted to engage against the inner sides of the corresponding walls of the section 1 and to also engage against the wall 4 of the section 1 when the mold is in a set up position. All of the walls of each section are of an increased width from one end toward the 0pposite end whereby the companion mold sect-ions will operate to produce or form a post of an increased diameter toward its lower end. The walls 5 and 6 of the section 1 have their longitudinal edges upset to present longitudinally extending flanges 7 which are adapted to recelve therebeneath the hooked ends 8 of the adjustable locking or retaining devices 9. Any suitable number of these retaining devices may be employed as may be found desirable to an operative assemblage and proper association of the companion sections of the mold, it of course being understood that said members are each of a difi erent size so as to correspond with the diflerent transverse diameters of the mold. The wall 4; of the section :2 of the mold extends slightly beyond the flanges 7 of the section 1 of the mold when both sections are set up. From this construction it is evident that the portions 10 of the retaining members 9 will be brought into effective contact with the wall 4 of the said section 2 and thereby effectually operate to hold both sections properly associated and against longitudinal relative movements.

In use the mold may be disposed vertically with its small end resting upon a suitable support, after which the concrete in a plastic state may be poured into the large end of the mold until sufficient amounthas been distributed within the mold as may be necessary to the manufacture of a post. At the requisite time the mold sections may be separated to permit of the removal of the post.

I claim A mold comprising a section tapered toward one end and provided with side walls terminating in right angularly-disposed flanges, said flanges being disposed in converging relation from one end of said sec tion to the other end thereof, a second section tapered throughout to flt within the first section and provided with a flat wall lying parallel with one of the walls of the first section and disposed beyond the plane of the flanges, and clamping devices adj ustable longitudinally of the mold and each having an intermediate body overlying the flat wall and end hooked portions extending over and beneath the flanges and operable when the clamp is moved in one direction on the mold to advance the body portion of the clamp against the flat wall and to move the second section into lateral engagement with the first section whereby to cause the free edges of the second section to mutually engage one of the walls of the first section.

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

GUSTAV H. FENSKE.
