METALLIC FENCE-POST.

Be it known that I, WILLIAM R. STEWART,

Ensley, in the county of Jefferson and State of Alabama, have invented new and useful Improvements in Metallic Fence-Posts, of which the following is a specification.

My invention relates to an improvement in metallic fence posts and has for its object to provide a post formed preferably of a metal pipe having one end split so that it may be spread or expanded in a novel manner after being inserted in the ground.

One feature of my invention consists in the novel means provided for effectively spreading the split end of the post after its insertion in the earth.

Another feature of my invention consists in the means employed for locking said spreading means in the expanded position assumed when the post is anchored in the earth.

A still further feature consists in a cheap that it will not fill with water which consists in filling the post to a point near the top with earth and capping it with cement or concrete composition.

As a modification of my invention I may form each post as a socket piece which proreceives a cement or composition post.

My invention further consists in the details of construction and arrangement of parts hereinafter more particularly described and claimed in connection with the preferred embodiment of my invention which is illustrated in the accompanying drawings, wherein similar reference numerals refer to similar parts, and in which Figure 1 is a sectional elevation of one of my improved posts shown as set in the ground before its split end is spread, the wedge being shown in side elevation. Fig. 2 is a view similar to Fig. 1, showing the wedge when the sections thereof have been forced apart to spread and anchor the split end of the post in the ground. Fig. 3 is a view similar to Fig. 2 showing the concrete filler inserted to hold the wedge in its expanded position and also the means for capping the post. Fig. 4: is a detail view of the split wedge for expanding the post. Fig. 5 is a perspective view of one of the segments of said wedge. Fig. 6 shows the pipe Specification of Letters Patent.

shortened to form a socket which receives a cement or concrete post. Fig. 7 is a view of the lower end of the post correspondin to Fig. 3, and showing a concrete wedge block used to expand the sections of the spreader and which is left in permanent engagement therewith.

My improved post is preferably formed of atubular metal body or pipe 1 havin the end thereof, intended to be inserted into the ground, split by a number of longitudinal slits, preferably four, out in the pipe from the end up for a distance of from eight inches to one foot, said slits being equidistantly spaced about the pipe to form legs which are adapted to be spread apart, as shown in Fig. 2. It being my purpose to insert the pipe to the desired depth in the earth before its end sections are spread apart, I prefer to accomplish this by first.

1. Each section has its top portion 3 tapering from its upper and outer periphery toward its inner edge, thus causing the assembled spreader to have a central depression formed by the inwardly sloping and converging tops of the wedge sections. \Vhen the assembled spreader is in the posi tion referred to, a suitable ramming device, such as a pipe or red 4, is passed down through the pipe 1 until its bottomend en gages the sloping top walls 3 of the wedge sections. This rammer is then driven down, acting as it is driven to spread the wedge sections apart and outwardly thereby expanding the legs or split end sections of the pipe until the latter are spread outwardly as shown in Fig. 2. been withdrawn, concrete or like substance 5 is inserted in the pipe 1 and tamped so that the spreader is effectively locked thereby in the expanded position its sections assume when they have been spread apart. Only a small quantity of concrete need be used, sutlieient to fill in around and above the wedge sections and hold the latter in position. The pipe 1s preferably filled above the concrete with earth 6 to a point within a few inches from the top and after the earth has been tamped down, a concrete or cement cap 7 is formed to close and seal the upper end of the pipe.

I prefer to make the wedge of concrete or cement composition as 1t will not be affected by the moisture of the earth and will be permanent, though hard wood or metal may be used if desired.

In Fig. 6 I illustrate a modlfied form of my invention in which the plpe 1s formed as a socket 8 which is similar to pipe 1, only shorter, and is inserted and anchored in the ground in the same manner. Into the upper end of this socket I introduce a concrete or cement composition post 9 and secure it in the socket by cement or mortar 10. The post 9 stands thus firmly rooted in the ground and makes a most durable and satisfactory post.

It will be noted that the pipe is spread after it is driven into the ground and that, in fact, in forming the post hole the earth into which the pipe is expanded has already been packed. I find that the pull required to draw my improved post out is nearly twice that of the ordinary posts of twice its diameter.

I have illustrated in Fig. 7 the use of a cone-shaped wedge 11 which may be made of concrete or cement composition and which is introduced with the spreader and adapted to receive the rammer and be forced downwardly to spread apart the sections of the spreader; This wedge 11 is left in position holding the spreader expanded, and concrete may be used above it or not as may be desired.

Having thus described my invention, what- I claim as new and desire to secure by Letters Patent, is

1. A device of the character described, a hollow metal body split longitudinally at its lower end, in combination with expansible wedging means located within the split portion of said body and adapted to be expanded to spread said split portion, substantially as described.

2. A device of the character described, a hollow metal body split longitudinally at its lower end, in combination with expansible wedging means located within the split portion of said body and adapted to be expanded to spread said split portion, and means to hold said wedging means in the position assumed after the end sections have been spread out, substantially as described.

8. A fence post formed by a hollow metal body having its lower end divided into sections by longitudinal slits, in combination with means to spread said sections apart after the post has been inserted in the ground, which means comprise a sectional sp reader having slanting upper surfaces to receive an instrument which spreads the sections of both spreader and pipe outwardly, and means to permanently space the sections of the spreader, substantially as described.

4. A fence post formed by a hollow metal body having its lower end divided into sections by longitudinal slits, in combination with means to spread said sections apart after the post has been inserted in the ground, which means comprise a sectional spreader having slanting upper surfaces to receive an instrument which spreads the sections of both spreader and pipe outwardly, and a composition filler inserted to hold said spreader sections in their expanded position. 5. The combination with a hollow post having an end thereof split, of a sectional spreader adapted to be inserted in the split end of said post and expanded by means passed lengthwise through the post, and a composition filler introduced in said post to hold said spreader sections expanded, substantially as described.
