CHARLES S. LONG, OF AURORA, ILLTNOIS.

FENCE-POST SPECIFICATION forming part of Letters Patent No. 387,085, dated July 3l, 1888.

(No model.)

T LU whom, i0' may concern:

Be it known that I, CHARLES S. LONG, a citizen of the United States, residing at Aurora, in the county of Kane, State of Illinois,

have invented certain new and useful Im provements in FencePosts and in the Method ofMaking the Same, of which the following is a specification, reference being had therein to the accompanying drawings.

Io My invention relates to an improved method of securing asphaltic or bituminous concrete bases to fence and other posts.

rlhe object of my invention is to provide a cheap and durable fence post having a base I5 firmly secured thereto, said base being composed of materials which are practically unaffected by thermal changes and which will not disintegrate under the influence of water or moisture.

2o My invention consists in the method of securing an asphaltic-conerete base to metallic fence-posts, which consists in heating the lower end of the metallic rod or bar, and while in such heated condition pressing the asphaltic concrete onto the same,the concrete heilig also heated to about the saine temperature as the lower end of the post, bar, or rod, whereby a perfect bond between the metallic bar or post and the base is secured, and all joints and 3o seams for the admission of water is obviated.

Figure lv is a side view of my improved fencepost and base. Fig. 2 is also a side View showing a hollow base. Figs. 3 and et are sectional' views ofthe base and posts. Fig. 5 is a View in perspective of the lower end of the post,

showing slits formed therein.

A indicates the main body of the post, which is, by preference, made of angle-iron, and of the form shown, but may be made of any suitable material or of any desired shape.

The flanges or wings on the lower end ofthe post are provided with slitsB, the portions between the slits being bent out of line with the main body ofthe post, so as to form teeth or projections which will hold the asphaltic concrete base more securely thereon.

Instead of the slits,l may simply form holes of any suitable shape through the wings or base of the post into which the concrete is 5c forced, which also serve as a permanent bond to hold the post in the base.

C indicates the base or anchor of the post, and is composed ofan asphaltic concrete, said concrete being formed by the adniixture of crushed and pulverized stone or othersimilaror suitable material with natural asphaltn1neitherTrinidad, Cuban, or other pure natural bitumen-said asphaltum being reduced to a liquid form by heat, and while the same is in a liquid and heated condition the crushed and pnlverized stone is added in suitable proportions, the stone being also heated so as to absorb the asphaltu in and form a perfect bond between the materials. The asphaltic concrete thus formed, and while in the heated condition above stated, is firmly pressed onto the lower end of the post or bar, said post or bar being previously heated to about the same or a littie higher temperature as the asphaltie concrete. The asphaltum, adhering iirmly to the heated iron, forms a perfectly tight joint be tween the two. The asphaltum and metallic bar or post contract in about the same ratio in cooling, thus preventing anyseams or cracks from forming between the iron and asphaltic concrete for the admission of water and moisture, which, under the expansive power of frost, would crack the base and ultimately destroy it, as is the case with clay or concrete.

The base C is, by preference, cylindrical in form; but may be of any desired shape and size to form a rigid and substantial support for the post and the fence which is secured thereto.

As before intimated, the asphaltic-eoncrete hase is not affected by the heat and cold of ordinary latitudes, and, being impervious to moisture, will not disintegrate or become worthless from the dampness and moisture of the earth; and, furthermore, owing to the pe culiar affinity of the asphaltuni for the iron, the lower end of the post or 'metallic bar, which is anchored in the base, will not become oxidized and injured,as is the case with hydraulic cement or other bases, for the reason that it is impossible to obtain a perfect bond between the post and base when formed of hydraulic cement, or when the base is not pressed thereon in a heated condition, and the water is liable to get in and oXidize the metal.

I am aware that in the casting of a iluid metal upon or around a metal bar it is common to heat the bar prior to casting, to pren vent chilling or unequal contraction, and such or base of heated asphaltic concrete7 as set 1o I do not claim. forth.

Having thus described my invention,what I In testimony whereof I affix my signature in claim isl presence of two Witnesses.
