PHILEMON STEWART, OF NEV LEBANON, NEV YORK, ASSIGNOR TOv AUGHAMPAUGH BROTHERS, OF SAME PLACE. f

CAST-IRON FENCE-POST.

Specification of Letters Patent No. 23,140, dated March 1, 1859.

To all whom it may concern: p

Be it known that I, PHILEMON STEWART, of New Lebanon, in the county of Columbia and State of New York, have invented certain new and useful Improvements in Cast- Iron Fence-Posts; and I do hereby declare that the following is a full, clear, and eXact description of the same, reference being had to the accompanying drawings, in which- Figure l, represents a perspective view of said felice post. F ig. 2, represents a front view of the same. Fig. 3, represents a horizontal cross section through the same.

The nature of my invention consists in a cast iron fence post, as an article of manufacture that will protect the ends of the fence rails, which are secured to the fence posts by projecting ianges of such a construction as to both give the rails a firm vertical support, as well as to `prevent any moisture from reaching and rotting said ends.

To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.

The fence post represented in Fig. l, is made of cast iron and formed with ribs ci, c, d, as shown in the cross section Fig. 3, to give it the required strength, and to make it suiliciently light for transportation.

The pot A, is either cast to the post or is secured to it by a tenon of the post passing through a'mortise of the foot, which tenon may besides be secured by a counterwedge.

g, represents ledges which are formed on the faces of the ribs a, and which are intended to support the ends of the rails, which are represented in red lines, in Figs. 2, and 3.

i, and m, `represent projecting flanges which are formed on the ribs ci, b, and d; the flanges m, are vert-ical to come against the sides of the rail, while the flanges t, are intended to cover the tops of the rail ends. The rail is fastened to the post by means of spikes, pins, screws or bolts, which are passed through the holes 0, and are driven into or through the rail. Thus it will be seen that when the rail is properly secured to this post, its ends will be efl'ectually protected against any moisture, as the rib (a and flange m, protect the sides and the flange 7L., the top `of the rail. It is a well known fact that wood exposed to moisture in the atmospheric air, will decay fast where the fibers are cut crosswise, as the moisture can then easily enter the grain of the wood. IVhen, therefore the ends of the rails are protected against moisture the rail will last al considerable time longer than where its ends are exposed to moisture.

The projections g', afford not only a firm vertical support to the rails, but 'they prevent the weight from coming upon the pin or bolt that holds them, and thus prevent the ends of the rails from splitting. Portions of the ribs of the post may be cast in open work, to save metal. I thus make a cheap, light, strong, and very durable cast iron fence post.

Having thus fully described the nature of my invention, what I claim therein as new and desire to secure by Letters Patent as a new article of manufacture, is-

A cast iron fence post constructed with flanges to protect the ends of the fence rails, against being split as well as against moisture and substantially in the manner herein described.
