BASE FOR FENCE-POSTS.

SPECIFICATION forming part of Letters Patent No..405,445, dated June 18, 1889.

Application filed November 30, 188B- Serial No. 292,189. (No model.)

To all whom it may concern/ Be it known that I, WILLIAM H. THOMSON, of the city, county, and State of New York, have invented a new and Improved Base for Fence-Posts, of which the following is a full, clear, and exact description.

This invention relates to fence-post supports, and has particular reference to that class of fence-post supports in which a felicepost base is employed which is stiffened and held in place by detachable cross stakes or pins inserted through the base and driven into the ground.

The invention has for its object to provide a fenceepost base having detachable anchor cross-pins which will project laterally from the base into the ground and interlock each other, thereby preventing them from being displaced and rmly holding the base in position.

The invention consists in a fence-post base having detachable interlocking anchor crosspins constructed and arranged as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar gures of reference indicate corresponding parts in all t-he views.

Figure 1 is an elevation of the fence-post base in position for supporting a post, with a portion of the anchorpins in cross-section- Fig. 2 is a vertical section thereof on the line o; x, Fig. 1, with a portion of the anchor-pins broken away and a portion in section. Fig. 3 is a plan view of the invention, with the post in horizontal section on the line .z z, Fig. 2. Fig. 4 is a detail of the invention, shoving base broken away and one of the anchorpins slightly drawn out of the base. Fig. 5 is a horizontal section of the invention on the line y y, Fig. 2. Fig. G is a perspective view of the invention, showing the base broken away and the anchor-pins in interlocked po sition. In the construction of the invention the base may be of any suitable form, either angular or round, of cast or wrought metal, in a single piece or in sections fastened together, and preferably formed with a pointed or tapering lower ond, whereby it may be driven into the ground.

As here shown, the base 1 is formed with sides 2,ihe tapering lower end 3,and asocket 4 at its upper end, which may loe of any desired shape to receive the lower end of a fencepost- 5. The base 1 is also formed with an internal chamber or cavity G, having inclined opposite aligning openings 7 8 9 10 irregularly placed in its walls for the interlocking anchor-pins 7, 8', 9', and 10 to extend through in a downwardly-inclineddirection crosswise to each other. i

The

pins

7, 8', 9, and 10 are of flat shape, with pointed ends 11, so as to readily enter the ground, and are formed with suitable heads. As shown, they are formed with square heads 12, which rest in countersunk recesses 13 in thc sides of the base, the recesses 13 havingnotches 14 in their edges, by means of which the heads 12 may be grasped with a tool to pull the anchor-pins out of their slots. The opposite aligning openings 7 8 9 10 are located in the upper part of the .base 1, so that a sufficient length of the base extends beneath t-he openings to be driven into the ground.

In securing the base 1 in the ground it is driven into the same until the upper opening of the openings S is about even with the surface of the ground and the lower openings 7 and S are beneath the surface, as shown in Fig. 1. The pins 7 3 0 10 are inserted through their openings in regular order to interlock each other, the pin 7 being first inserted through its openings 7 and driven into the ground until its head 12 enters its recess 13. The pin 8' is then passed through its upper opening S, through an opening 15 in pin 7', through its lower opening 8, and driven into the ground until its head 12 enters its recess 13. The pin 9 is then inserted through its openings 9 and driven into the lground until iis head 12 enters its recess 13', and, lastly, the pin 10 is passed through its upperbpening 10, through an opening 16 in pin 9', through its lower opening 10, and driven into the ground until its head 12 enters its recess 13.

By means of the foregoingdescribed arrangement of interlocking anchonpins the base 1 will be held firmly in the ground and will remain steady in upright position, so as to prevent the post from sagging or tipping. The anchor-pins cannot become separately IOO loosened or displaced, as, being interlocked, they must move together. The anchor-pin 10, last inserted, may be secured in place by any suitable means. As here shown, it is fastened by means of a pin 17 passing through a hole 18 therein and extending on each side of the lower slot 10 adjacent to base 1. In order that the pin 10 may clear the pins 7 and 8', the pin 7 is formed with a notch 19 on one edge thereof and the pin S with a notch 2O on one edge thereof. lVhen the anchor-pins are in position, the pins 7 and S will be concealed in the base 1 and beneath the ground, and a portion of the

pins

9 and 10 will appear above the ground.

To remove the base, the pins 7 8 9 10 are drawn out in the reverse order from that in which they were put into place, the pin 17 being removed from pin 10 and the latter withdrawn from place, and so on in succession, ending with pin 7 when the base 1 may be pulled up. lt will thus be seen that the base 1 may be readily secured in the ground by driving it without iirst having to excavate a hole and then securing the anchor-pins in place, thereby affording a firm and stable fence-post base.

It is obvious that any number of anchorpins desired may be employed, and that they may be made round instead of fiat. The base 1 may be also made with any number of sides.

While I have described a specific construction of parts, I do not desire to limit myself thereto, as the parts may vary in detail without departing from the essential features of the invention.

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

l. A fence-post base formed with a point to enter the ground and having detachable interlocking anchor-pins extending crosswise thereto and adapted to enter the ground, substantially as shown and described.

2. A fencepost base formed with openings irregularly located therein, in combination with interlocking anchor-pins which extend through the openings and project laterally from the base, substantially as shown and described.

3. A fence-post base formed with openings irregularly located therein, in combination with interlocking anchor-pins which extend through the openings and project at an incline downward from the base, the anchorpins being inserted through the base in regular order to interlock each other, with means for fastening in place the pins last inserted, substantially as shown and described.

4E. ln a fence-post base, substantially as described, the base 1, formed with internal chamber (i, the inclined aligning opposite openings 7 S 9 10 in the walls of chamber 6, a fencepost socket 4 at its top, and a tapering lower end 3, substantially as shown and described.

5. A fence-post base 1, formed with internal chamber 6, the inclined aligning opposite openings 7 8 9 l() in the walls of chamber (5, a fence-post socket 4 at its upper end and the tapering point 3 at its lower end, the upper openings 7 S 9 10 having countersunk recesses 1S, with notches 14 in their edges, in

pins 7, S', 9', and 10, having heads 12, fitting recesses 13, and inserted in regular order through openings 7 S 9 10, respectively, to interlock each other, the pins 7 and 9 having openings 15 and 16 for the passage of pins S VILLIAM H. THOMSON.
