GROUND ANCHOR Filed Jan. 4, 1957 INVENTOR. PAUL M. MAZUR.

BY W584 ATTORNEY.

United States Patent GROUND ANCHOR Paul M. Mazur, Fiddlers Creek Farm, N. J.

Application January 4, 1957, Serial No. 632,458

2 Claims. (Cl. 189-90) This invention relates to a dead man or ground anchor and, more particularly, to a ground anchor which serves to convert a horizontal pull into a vertical thrust thus finding utility on farms, in army services and in connection with trucks of all kinds.

The chief object of the present invention is to provide a ground anchor which serves as an anchorage point for a cable or cable and pulley.

An object of the invention is to provide a simple, inexpensive ground anchor which may be securely fixed in the ground to support heavy horizontal traction.

A further object is to provide a ground anchor which possesses a great earth engaging area and which is compact, easy to operate and easy to install or set up. Other objects of the invention will be readily perceived from the following description.

This invention relates to a ground anchor adapted to convert a horizontal pull into a vertical thrust which comprises, in combination, a plate member adapted to rest on and be supported by the ground and to transfer forces over a relatively large area of the ground beneath the plate, said plate member having a plurality of openings therein through which spikes or pins may be driven into the ground to hold the plate in place, reenforcement members extending longitudinally of the plate, and an attaching member to which a cable or chain may be secured.

The attached drawing illustrates a preferred embodiment of the invention, in which:

Figure 1 is a top plan view of the ground anchor of my invention;

Figure 2 is a bottom plan view of the ground anchor shown in Figure 1;

Figure 3 is a view in elevation of the ground anchor shown in Figures 1 and 2; and

Figure 4 is a sectional view of the ground anchor in use.

Referring to the drawing, there is shown the ground anchor of the present invention which is adapted to convert a horizontal pull into a vertical thrust. The anchor comprises a substantially flat, plate-like member 2 adapted to rest on and be supported by the ground on which it rests. It will be appreciated this member serves to transfer forces over a relatively large area of the ground beneath it. At one end of plate 2, a plurality of spaced openings 3 are provided placed substantially in alignment across the plate. Each of the openings 3 is surrounded on one side of the plate by collars 4 which serve to guide pins or spikes 5 through the plate to be driven into the ground and assist in supporting the spikes in operating position. Preferably, the collars are inclined at an angle in opposition to the direction of forces to be resisted by the anchor.

On the face of plate 2, two longitudinally extending strips or rods 6, 7 are provided adjacent opposite sides. The strips 6, 7 preferably, are in contact with outer collars 4 and serve to reenforce the collars and plate. Similar strips 8, 9 are provided which extend at an angle between the inner collar 4 and the outer strips 6, 7 for purposes of reenforcement.

An attachment bar 10 extends laterally across and spaced from plate 2 and is secured to strips 6, 7. A cable 7 or chain 11 may be secured to bar 10 as shown in Fig ure 4.

A plurality of teeth 12 are attached to or formed in the ground side of plate 2. Teeth 12 are embedded in the ground to hold the anchor in position during driving of the spikes or pins into the ground and aid in resisting forces applied to the plate.

In operation, the anchor is placed on the ground and is attached to the ground by embedding the teeth 12 therein. Spikes or pins 5 are then placed in collars 4 and driven into the ground by any suitable means thus securely anchoring the dead man to the ground. A cable 11 or cable and pulley is then attached to bar 10 and the device is ready for use. The ground anchor provided by the present invention is simple, compact and economical in construction. It finds use particularly on farms although, of course, it may be used in many other places. The ground anchor readily converts a horizontal pull into a vertical thrust thus supporting heavy horizontal traction.

While I have described a preferred embodiment of the invention, it will be appreciated the invention is not limited thereto since it may be otherwise embodied within the scope of the following claims.

I claim:

1. In a ground anchor adapted to convert a horizontal pull into a vertical thrust, the combination of a plate-like member adapted to rest on and be supported by the ground and to transfer forces over a relatively large area of the ground beneath the plate, said plate member having a plurality of openings therein through which spikes or pins may be driven into the ground to hold the plate in place, collars about said openings inclined rearwardly at an angle to oppose forces applied in a substantially horizontal direction, outer reenforcement members on opposite sides of said plate member engaging said collars and extending forwardly longitudinally of the plate from the inclined outer collars, second reenforcement members extending at an angle to said first reenforcement members engaging an inner collar and extending from the inner collar to the outer reenforcement members, and an attaching member extending between and secured to said longitudinally extending reenforcement members to which a cable or chain may be secured.

2. In a ground anchor adapted to convert a horizontal pull into a vertical thrust, the combination of a plate-like member adapted to rest on and be supported by the ground and to transfer forces over a relatively large area of the ground beneath the plate, said plate member having a plurality of openings therein through which spikes or pins may be driven into the ground to hold the plate in place, collars about said openings inclined rearwardly at an angle to oppose forces applied in a substantially horizontal direction, outer reenforcement members on opposite sides of said plate member engaging said collars and extending forwardly longitudinally of the plate from the inclined outer collars, second reenforcement members extending at an angle to said first reenforcement members engaging an inner collar and extending from the inner collar to the outer reenforcement members, a plurality of teeth on the ground side of said plate adapted to be embedded in the ground to aid in securing the plate in place, and an attaching member extending between and secured to said longitudinally extending reenforcement members to which a cable or chain may be secured.
