Specication of Letters Patent.

Patented Apr. 6, 1915.

Application filed April 29, 1913, Serial No. 764,467. Renewed January 5, 1915. Serial No. 671.

T0 all 'whom t may concern:

Be it known that I, ALBERT B. CHANGE, a citizen of the United States, residing at Centralia, in the county of Boone and State of Missouri, have invented certain new and usefulv Improvements in Land-Anchors, of which the following is a specification.

This invention relates to new and useful improvements in earth anchors and comprises not only a novel and improved construction of the anchor but' a new method of installation, which is directly reverse to the method now 1n vogue, whereby the anchor strain is not in' line with the entrance of the anchor but approximately at right angles thereto. y

In carrying out my invention, a hole for the entrance of the anchor head is bored approximately at right angles to the line of strain to be applied. The anchorrod is forced or driven throughthe solid earth into the hole thus bored for the anchor head and the head of the anchor rod arranged to assume a position approximately in the center of the hole. The anchor head is then engaged by any means for holding by my special holder, and inserted into the hole and slipped over the head of the anchor rod, the means of engagement between the, holder and the anchor head being such that by a slightupward movement of the holder, it may be disengaged from the anchor head and Withdrawn.

With the foregoing and other objects in view that will appear as the nature of the invention is better understood, the invention consists in the novel features of construction and the. method of installation illustratedy and described in the accompanying drawings. Y

Figure 1 is a view illustrating the application of the earth anchor. Fig. 2 is a partly sectional view, and partly side. view of the device. Fig. 3 is an inverted view of the` anchor detached from its adjunctive parts. '1 Fig. 4 is an elevation of the anchor rod showing also the protector head bolted over the eye. Fig; 5 is a perspective view of the anchoradjusting or positioning contrivance.

Referring to the drawings for a more particular description of the invention and which drawings are for illustrative purposes only and are therefore not drawn to scale, 1 indicates the anchor rod, 2 a head at the lower end thereof, 3 the anchor head which is engaged by the head of the `anchor rod, 4

the holder attached to the end of a tampingf bar and 5 the-hole which is bored into the earth approximately at right angles, or exactly at right angles, as the case may be,

with the yanchor rod and the line of strain.

The anchor rod 1 is provided at the upper end with the loop 6 for suitably connecting it with the lower end of the cable or connection 7 between the eye end of the anchor rod and the pole or post 8. Y

While my earth anchor is primarily del signed for use in connection with telephone,

telegraph, electric light and trolley poles, I

do not wish to limit myself to this particular use as it is obvious that the same principlemay be applied to silos, smoke stacks and all such requiring an earth anchor.

The anchor head (Fig. 2) v3 as shown in 75 Fig. 1 is arranged longitudinally in the hole 5 bored in the earth and is of concavo-convex form in transverse or cross section being arranged with its convex nface outwardly, and provided on its inner face with 89 the inwardly inclined reinforcing ribs 9, 9 and 10. The anchor head -is further provided between the ribs 9 with the upwardly tapering slot 11 and at its center at the in- 12 to receive the head 2 formed at the lower end of the anchor rod 1.

The head 2 of the anchor rod is preferably ner or upper end of said slot with the socket 815 'of cone-shaped form'rounded at the base to fit in the socket 12 of the anchor head. The 90 possible skidding or slipping should the hole 5 for the anchor head be bored at a less angle than right angles to the strain.

The anchor 'head is inserted into the bore or hole 5 by any means of holding or by my special-holder-4 at the end of the tamping bar and the slot 11 passed over the head 2. at the lower end of the anchor rod 1 for the purpose of engaging the head 2 at the lower end of the anchor rod with the socket 12 in the anchor head.

The upper end of the anchor head is provided with the centralv notch 13 and the transverse perforation 14 'disposed in longitudinal alinement with the notch, while the ico holder 4 is provided with the knob 15 and 110 the tongue 16 to lengage the perforation and notch, respectively, whereby the holder may 'i be detachably engaged with the upper end of the anchor head for the purpose of 1nserting it in position. lin other Words, the holder' is engaged with the anchor head in the same manner as a stove shaker with the grate. When the anchor head is -engaged with the anchor rod, by a slight movement, the holder may be disengaged from the former and Withdrawn.

The numeral 7a indicates a protecting head that clamps over the eye 6 at the upper end of the anchor rod l for the purpose of protecting the eye of the rod lin case it is necessary to drive the anchor rod through the earth with a hammer.

l attach particular stress and importance to the method of installation in which the anchor head is inserted in the ground in a hole bored at right angles, or approximately at right angles, to the line of strain or position of the anchor rod, also to the engagement or attachment of anchor rod, Wire or cable, to the anchor head after their installation in the earth.

iaeasao From the foregoing description taken in connection with the drawings, it is thought that the construction and advantages of this invention Will be readily understood without requiring a more extended explanation.

Having described my invention What l claim as new, is

A device of the type described includingn an anchor head having an upper convex surface, said anchor head being equipped upon its said convex surface With a transverse rib to prevent slipping action thereof, said anchor-head also having a central oriiice, the Walls or which taper upwardly and provided with a slot merging into said oritice, and a rod member itself having a head adapted to interlock with said orifice ot the anchor head.

lin testimony whereof ll aiin my sig-nature in presence of two Witnesses.
