Sept. 9, 1930. H. M. MILLIKEN LAND ANCHOR Filed April 1, 1929 ENVENTOR HM. Mill Ilka n BY ATTORNEY strong and one which Patented Sept. 9, 1930 UNITED STATES PATENT OFFICE HARRY M MI LIKEN, or cnnBoYeAN, MICHIGAN, ASSIGNOR or ONEJ-IALF TO re (TOSKEY ENGINEERING COMPANY, or LPETOSKEY, MICHIGAN, A COPARTNERSHIP COMPOSED OF R. I). TRIPP AND T. W. WILCOXEN LAND ANCHOR Application filed April 1,

My invention has for an object to provide a device for anchoring the guy wires of telephone, telegraph, electric light poles and 0th er structures.

y The invention has for another object th provision of an anchor with removable driving rod whereby thetplate or blade part may be sunk into the groundand the driving rod removed if desired so as not to leave any projections above ground which might cause accidents; further the removability of the driving rod enables the driving rod to be used with numerous anchor plates or blades. 7

Again it is an object to provide an anchor of a simple structure which will be light but 7 maybe manufactured at low cost.

F urther it is an object to provide an anchor that can be installed by inexperienced labor in a few minutes, and a further and i1np0rtant object is to provide a land anchor that will, under strain,dig itself deeper into solid earths a Other objects will in part be obvious and in part "be pointed out hereinafter.

To the attainmentofthe aforesaid objects and ends, my invention consists in the novel features of construction and in the combination, connection and arrangement of parts, hereinafter more fully described and then pointed out in the appended claims.

In the drawings i Figure 1 is a side elevation illustrating the invention in use, the driving rod not having been removed.

Figure 2 is a front elevation of the anchor plate or blade per se. 7 a

Figure 3 is a rear elevation of the same;

Figure 4 is a central vertical longitudinal section thereof.

Figure 5 is a plan view thereof.

Figure 6 is an enlarged cross section on the line 66 of Figure 3.

Figure 7 is an enlarged vertical section on the line 7-7 of Figure 3.

Figure 8 is a detail plan of an anchor rod showing its relation to the anchor plate, the plate being indicated in dotted lines.

Figure 9 is an enlarged detail of the driving rod.

1929. Serial No. 351,767.

In the drawings in which like numerals of reference indicate like parts in all of theiigures, 1 represents a telegraph pole whose guy wire 2 is to be anchored. 3 represents the anchor rodto Whose eye 4 the guy 2 is attached and which is provided with an arrow head5, the base of which is concaved as at 6, the'curvature corresponding to the curvature of the convexed rear face of the anchor plate or blade 7. r y Q a The anchor plate or blade 7 is concaved on its front face as at 8 and on its rear face is provided with vertical stifleners 9 at each edge, the stiffeners tapering toward the point of theshovel portion 11 of the plate. About one-thirdof the distance from the point of the'plate there is provided a cross channel iron stiffener 10 on the rear face of the plate, and the shovel portion 11 is provided wit-ha vertical slot 12 whichextends up and merges with a continuation of the slot 13 in the cross channel stiffener '10.

If desired a stiffener 14: may be welded or otherwise secured to the rear face of the plate around the slot 12.

15 is the driving rod having an impacting head 16 and a slotted endli', the latter being designed to fit over the upper edge of the anchor plate 7.

In using my invention, the anchor rod, or a guy rod as it is sometimes called, is driven 1nto the earth on the direct line of strain and to approximately the desired depth.

to a point where the guy rod is intersected The anchor plate 7 is then placed in the hole, the driving rod placed over the plate and the plate driven into solid earth until the arrow head 5 of the anchor rod is in alignment with the slot 12. The anchor rod is then given a slight additional tap to drive the arrow head through the slot and the rod is given a quarter turn to bring the arrow head crosswise of the slot withinthe transverse channel 10 as best indicated in Figure 8. The drivingcrod may then be removed and the hole tamped full of earth if desired.

With the construction shown and described Tilt the tendency of the anchor, when strains are applied along the length of the anchor rod 3, is to more downwardly and bury itself deepor int-o solid ground. This is due to the fact that the shovel end of the anchor plate is curved forwardly and the point of connection between the anchor plate and the anchor rod is adjacent the shovel end of the plate or a distance below the mid-length of the anchor plate. Thus the earth abutment aga nst which the anchor plate is pulled and which lies above the line of the anchor rod 3 offers more resistance than does the earth opposing the shovel end of the plate as the shovel end of the plate is curved forwardly it tends to follow an arc, the radius of which is the radius. of curvature of the shovel end of too plate and thus bury itself deeper into solid ground. In other words, instead of the strains on the guy wire tending to loosen the anchor the construction and arrangement is such in this case that the strains tend to tighten the anchor.

\Vhile exact proportions of parts are not essential to my invention, 1 have found from practical experiment that a practical structure may be provided by making the anchor plate of No. gauge sheet steel concaved at the front face on an 8 inch radius, curving the shovel end forwardly on :1 212 inch radius and providing 1% inch sti'lieners at the sides on the back and a 2 inch channel iron stiil'ener 10 where the shovel part of the blade merges with the body of the blade proper. The slot 12 may be in length 6 inches and in width of an inch. T he diameter of the anchor rod may be of an inch and the head 5 of the anchor rod may be 2 inches long with a base 3 inches. wide, the radius of curvature of the base being approximately 8% inches to fit the concaved back of the anchor plate which is of approximately the same radius of curvature. The anchor rod may be of a length of (5 feet overall.

The driving rod may be made of 1% inches diameter mild steel and of any length found desirable.

From the foregoing description, taken in connection with the accompanying drawing, it is thought the complete construction, operation and advantages of my invention will be clear to those skilled in the art to which it relates.

hat I claim is:

1. Means to anchor guy wires and the like con'iprising an anchor rod, an anchor plate of concavo convex form in cross section, the front face being concave, vertical stiifeners at the sides of the plate and projccting from the rear face thereof, said plate having a forwardly curved point-ed shovel end, and means to connect said rod to said plate adjacent the shovel end.

2. Means to anchor guy wires and the like comprising an anchor rod having an arrow head whose base is concaved, an anchor plate of concave convex form in cross section, the front face being concave, vertical stifl'eners at the sides of the plate and projecting from the rear face thereof, said plate having a forwardly curved pointed shovel end, said plate having a slot and said rod having its head adapted to pass through said slot in one position and lie with its c-oncaved base against the concaved back of said plate when in another position.

3. In land anchors, a plate or blade comprising an elongated body having approximately the lower third of its length tapered to form a shovel-like portion, vertical and transverse stiffeners projecting from the rear face of said blade, said blade in its shovel-like portion being slotted to receive an anchor rod.

i. In land anchors, a plate or blade comprising an elongated body having approximately the lower third of its length tapered to form a shovel-like portion, said shovel-like portion being curved forwardly, vertical and transverse stiffener-s projecting from the rear face of said blade, said blade in its shovel-like portion being slotted to receive an anchor rod.

5. In land anchors, a plate or blade comprising an elongated body having approxi mately the lower third of its length tapered to form a shovel-like port-ion, vertical and transverse stiffeners projecting from the rear face of said blade, said blade in its shovel-like port-ion being slotted to receive an anchor rod, said blade having its front face concave in cross section.

6. In land anchors, a plate or blade comprising an elongated body having approximately the lower third of its length tapered to form a shovel-like portion, vertical and transverse stiifeners projecting from the rear face of said blade, said blade in its shovellike portion being slotted to receive an anchor rod, said blade having its front face concave in cross section, and having its rear face convexed in cross section.
