EARL H. DRESSER, OF LITCHFIELD, MICHIGAN.

ARTIFICIAL-STONE POST.

SPECIFICATION forming part of Letters Patent No. 741,469, dated October 13, 1903.

Application filed July 19, 1902.

To all whom it may concern/.-

Be it known that I, EARL H. DRESSER, a citizen of the United States, residing at Litchfield, in the county of Hillsdale and State of Michigan, have invented a new and useful Artificial-Stone Post, of which the following is a specification. u

This invention-relates to artificial-stone posts adapted to be used as fence-posts, hitchplicity,durability,and general efficiency; and

with these ends in view it consists in the improved construction of said post, which will be hereinafter fully described, and particularly pointed out in the claim.

In the accompanying drawings, Figure 1 is a vertical sectionaliview of an artificial-stone post constructed in accordance with the principles of myinvention. Fig. 2 is a side view showing one of the braces. Y

Corresponding parts in both figures are i`ndicated by similar numerals of reference.

In carrying out my invention a plastic mass consisting of Portland cement, filling--such v ercise its binding qualities.

as sand, crushed stone, cinders, or the like separately or in combination-and water is preferred, such mass being, as stated, merely sufficiently moist to enable the cement to ex- A mold is provided, preferably of a tapering shape, into which the mass is shoveled to the extent of about one-half the desired thickness of the post, which latter in the drawings is designated 1. Brace-rods 2 of a length nearly equal to that of the post and provided with coiled' ends 3, terminating in inner members 4, which lie practically parallel to the bodies of said rods, are then placed in the mold parallel to the edges thereof and with their coiled ends extendinginwardly, and additional plastic material is then shoveled into the mold to the desired thickness of the post andthoroughly tamped. The material employed be- Serial No. 116,275. (No, model.)

ing of a quickly-setting nature, the mold may be almost instantly removed, thus enabling the manufacture of another post to -be proceeded with.

The post is provided with transverse perforations 5, suitably spaced apart vand disposed between the brace-rods 2 2.

From the foregoing description ,taken in connection with the drawings hereto annexed, the advantages of my invention will be readily understood. The method or process of'manufacture is extremely simple and of such a nature as to admit of theemployment of the cheapest labor. This in connection with the fact that but few molds are required in the manufacture of the posts greatly decreases the cost of manufacture as compared with that-of artificial-stone posts heretofore employed. In the event of the fracture of my improved post at any point intermediate of its ends the parted pieces will be positively prevented from separating, owing to the coils atk the ends of the brace-rods which extend through the entire length of the post and the resiliency of which in the event of fracture not only serves to hold the fractured pieces together, but also to retain them in connection with each other with .a certain degree of tension, whereby` the post though broken will be retained in normal operative position. This would not necessarilybe the case if instead of these brace-rods short rods breaking joints with eachother were employed. The principal advantage of my invention, however, resides in the che'apness and simplicity of manufacture of my improved post, which enables it gto be utilizedwith great advantage not only in localities where timberis scarce, but also in localities where timber is comparatively abundant, the economy of my improved artificial-stone post resulting not only from its comparative indestructibility, but also from the fact that it may actually be produced at less expense than a wooden post of the same dimensions.

Having thus describedmy invention, I claiml An artificial-stone post consisting of a concrete mass having embedded ,therein two oppositely-disposed longitudinal brace-rods ex-v tending practically through the entire length g renee@ of the post, the ends of which are provided vided with suitably-spaced transverse perfowith inturned coiled ends 3 terminating in rations between the longitudinal bracerods.
