ANCHOR.

SPECIFICATION foil-idling part of Letters Patent No. 787,017, dated April "11, 1905. I Application filed September 20, 1904:. Serial No. 225,245.

To all whom, it Wmy concern:

Be it known that I, J OHN W. VVITMER, acitizen of the United States of America, and a resident of Lima, in the county of Allen, State of Ohio, have invented certain new and useful Improvements in Anchors, of which the fol lowing is a specification.

This invention relates to certain new and useful improvements in ground-anchors, and more particularly to that class of anchors that are designed to be sunk in the ground and whichare connected, by means ofstays, guys, &c., to trolley and similar poles, to fenceposts, &c., or to any other device necessary to be supported.

The object of my invention is to provide an anchor so simple in construction that it may be. formed of castings, and therefore sulficiently cheap to be placed within the reach of almost every field where such anchors are necessary.

In its preferred embodiment my invention consists of an anchor formed of two substantially similar castings formed with wedgeshaped ribs on their inner surfaces, with which coact an expander which is designed to ride on said ribs and spread the upper ends of the castings into the ground, and thus securely hold the anchor in position.

Various other details will be hereinafter re ferred to, and the invention will be particularly set forth by the claims at the end hereof.

In the accompanying drawings, Figure 1 represents a sectional view of my improved anchor in the position it occupies just after it has been placed in the ground. Fig. 2 is a similar view after the parts have been separated. Fig. 3 is a perspective view of one of the parts of the same. Fig. 1- is a similar view of the expander for separating the two main parts or castings. I

Referring now to the details of the drawings by numerals, 1 and 2 represent a pair of castings which are almost similar in construction, each of them being substantially semicircular in cross-section and one of them having a lug 5 cast at one end, which enters a corresponding recess 6 in the opposite casting, as clearly shown in Fig. 1. When the two castings are placed together, they form an anchor which is shaped very much like the common form of cartridge in that their lower end is made somewhat Cone-shaped, as indicated at 7, while the body or main portion is formed with a series of 'annular ribs 9 and 10, as clearly indicated in the drawings. The interior of-each .of these castings 1 and 2 is formed hollow, and running almost, the entire length of each casting is an inclined rib 12, formed integral with the castings proper. 'At the upper end of each of the castings and above the inclined ribs 12 there is formed a head 14, and this head is formed with a recess 16, through which passes the stem of the expander, which will be hereinafter described, and each of these heads 14 is also provided with a recess 18, the purpose of which will be hereinafter stated. It will be manifest that these two main castings are formed so simple that they may be cast in the cheapest possible manner, and they are therefore cheap enough to be used in places where it is necessary to have an anchor of the lowest possible cost.

' Ooacting. with the two main parts or castings 1 and 2 ,is an expander consisting of a head 17, to which may be secured inany desirable manner a rod 19, formed with an eye 20 at its upper end, to which the stay, guy, or similar device may be readily secured. served that this head is somewhat the shape of a common piston and is arranged to slide within, the recesses formed within the castings 1 and 2; but in order that it may ride freely upon the inclined ribs 12 the expander is formed with two recesses 22, as clearly indicated in the drawings. The upper side of the expander on opposite sides of these grooves or recesses is formed with a pair of lugs or projections 24:, and these lugs are so situated that when the expander is drawn to the extreme upper position, as indicated in It will be ob- Fig. 1, said lugs fit within the recesses 18, hereit may not be out of place to describe its operation,as follows: A hole of sufficient diameter and of the proper depth is first formed in the earth by any suitable tool, the hole preferably being slightly less in diameter than the outside diameter of the anchor. After the parts of the anchor have been assembled by placing the expander 17 Within the two parts of the anchor, with the expander at the lower end of the anchor, the whole device is inserted in the ground to the lower end of the hole which has just been formed, and by exerting sufficient force on the rod 19 the expander is drawn upward, so as to spread apart the castings l and 2, so tha u they will assume the position shown in Fig. 1. The hole above the anchor may now be filled with earth, broken stone, or any suitable material and properly tamped, when the anchor will be found to be securely held in position. It will be observed that there are quite a number of ribs 9 and that these ribs are substantially flat on their upper sides, and they thus offer the greatest resistance possible to the withdrawal of the anchor.

It is obvious that changes and modifications may be made in the form and construction of my anchor without departing from the invention as set forth in the appended claims.

What I claim as new is 1. A ground-anchor formed of two hollow portions and having an inclined wedge therein, and an expander located within said anchor and coacting with said wedge to separate the ends of the anchor from which said expander is operated, substantially as describedf 2. A ground-anchor formed of two hollow portions having an inclined wedge therein, and an expander located within said anchor and coacting with said wedge to spread the parts of the anchor; said expander and said anchor having coacting portions whereby the two parts of the anchor are locked by said expander, substantially as described.

3. A ground-anchor formed of two hollow portions,each having an inclined wedge therein and a head at the upper end of said wedge,

and an expander located within the hollow anchor and coacting with said wedges to spread the parts of the anchor; said expander and said heads having coacting portions locking the parts of the anchor together, substantially as described.

4. A ground-anchor formed of two hollow portions,each having an inclined wedge therein and a head at the upper end of said wedge, said portions also having a coacting lug and recess at their lower ends; and an expander located within said hollow portions and coacting with said wedges to expand the same, substantially as described.

5. A ground-anchor formed of two hollow portions, each having an inclined wedge therein and a head at the upper end of said wedge, each of said heads having an opening or recess therein, and an expander located within said hollow portions and coacting with said wedges to expand the same, said expander having lugs adapted to enter the openings in said head to lock the same, substantially as described.

6. A ground-anchor formed of two hollow portions, formed substantiallycartridge shape, and having inclined wedges on their inner sides, and an expander located within said hollow portions and coacting with said wedges to separate the ends of the anchor from which the said expander is operated, substantially as described.

7. A ground-anchor formed of two hollow portions,forincd substantially cartridge sl 1a 1 )0, each having an inclined wedge therein and a head at the upper end of said wedge. and an expander located within said hollow portions and coacting with the wedges to expand the same, said expander and said heads having coacting portions locking the parts of the anchor, substantially as described.

Signed by me, at Lima, Ohio, this 17th day of September, 1904.
