Abstract

A spade for an H-beam fence post is made from a steel plate having a flat portion that engages the outside of one flange of the post. A pair of spaced apart tabs at the lower end of the plate extend upwardly from the flat portion so as to form two Ushaped members which fit over the lower end of the post one on each side of the web of the post. A pair of inwardly extending tabs at or near the top of the flat portion extends over the inside of the post flange toward its web. When the post is driven into the ground it carries the spade with it and the top tabs or other means hold the spade against the post.

PATENTED BEE 4 73 SHEET 1 UF 2 FENCE POST SPADE This invention relates to a spade for a fence post and more particularly to a spade for anchoring an H-beam fencepost to the ground. There are manyways of anchoring fence posts to the ground. One common way is to embed the post in concrete, but this is costly, especially in locations where concrete is not readily available. Other methods include separately driving the post and anchors into the ground and bolting the anchorsto the post or separately driving metal fixtures which expand at oblique angles when embedded in the. ground.

Spades and specially constructed posts have also been proposed, but these are expensive to manufacture and difficult to assemble and/or drive. Carpenter U.S. Pat. No. Re. 9005 dated Dec. 30, 1879; Bayliss U.S. Pat. No. 319,877 dated June 9, 1885; Gough et a1. U.S.Pat. No. 357,314 dated Feb. 8, 1887; Sprague U.S. Pat. No. 1,165,459 dated Dec. 28, 1915; and Harding U.S. Pat. No. 1,399,426 dated Dec. 6, 1921 are illustrative of the prior art.

It is an object of my invention to provide a spade for a standard fence post which is easy and inexpensive to manufacture.

Another object is to provide such a spade which prescuts a minimum of additionalresistance to driving of the post into the ground. i

A further object is to provide such a spade which can be assembled at the fence location without the use of separate fastening means. l

A still further object is to provide such aspade which does not require any change in the method of driving the post.

These and other objects will be more apparent after referring to the following specification and attached drawings, in which: 1

FIG. 1 is an elevation of a post and spade of my invention driven into the ground;

FIG. 2 is a top plan view of the spade of FIG. 1; FIG. 3 is an elevation taken at right angles to FIG. 1; FIG. 4 is a view similar to FIG. 1, showing a second embodiment of my invention;

FIG. 5 is an elevation taken at right angles to FIG. 4; FIG. 6 is a view taken on line VIVI of FIG. 4; and FIG. 7 is a perspective view of a third embodiment o my invention.

Referring more particularly to FIGS. 1 to 3 of the drawings, reference numeral 2 indicates an I-I-beam fence post having two flanges or sides 4 connected by a web 6. Spade 8 of my invention, which is preferably formed from a single steel plate, has a flat portion 10 which bears againstone of the flanges 4. It will be seen that the bottom of the flat portion 10 has a width approximately the same as the flange 4 with its longitudinal edges tapering upwardly and outwardly. A pair of spaced apart tabs 12 are provided at the bottom of the spade and extend upwardly one on each side of the web 6 so as to form two U-shaped members with their open ends upwardly. The bottom of post 2 is received in the U-shaped members and bears against the bottom thereof. A pair of inwardly extending tabs 14 are provided at the upper end of flat portion 10 with a space 16 between their ends to receive web 6 when the tabs 14 extend over the inside of web 4.

The spade 8 is preferably made byblanking out a flat form from about 12 gauge steel, cutting a bottomnotch therein and making slits therein for thetop tabs. The

upper and lower tabs are then formed with a mechani cal press die.

To drive a post the spade 8 isfirst assembled on post 2 by slipping'the lower end of one of the post flanges through the upper tabs 14 and sliding the postdownwardly until the same post flange seats in the bottom of the .U-shaped members as shown. The post is then driven in the usual member driving the spade ,withit. The tabs 14 act as holding means to prevent the spade from moving outwardly from the post- The embodiment shown in FIGS. 4, 5 and 6 isthe same as that of FIG. .1 except that the tabs 14 are replaced by means of tabs 20 which are punched out from the flat plateportion 10 below the top thereof.

The driving operation is the same as that of the first embodiment.

The third embodiment shown in FIG. 7 is also the same as that of the first and second embodiments except for the top holding means. In this embodiment the upper tabs are eliminated and a plate .22 is provided at the top of flat portion 10. The plate22 may be integral with or welded to flat portion 10 and is providedwith an opening 24 of such size as to receivethe entire post 2. The driving operation is otherwise the same as in the other embodiments.

.While several embodiments of my invention have been shown. and described, it will be apparent that other adaptationsand modifications may be made with out departing from the scope of the followingclaims.
