ANCHOR.

Application filed March 18, 1928. Serial 3T0, 95,715.

This invention relates to certain improve ments in anchors and has relatlon more particularly to a device of this kind especially.

designed and adapted for use in connection with guy lines or the likefor use in connection with telegraph poles and the like, and it is an object of the invention to provide a device of this general character constructed in a manner wherein the strain imposed thereon results in an effective locking of the anchor in applied or working position.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved anchor whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, 1 will now proceed to describe the same with reference to the ac companying drawings, wherein Figure 1 is a view partly in section and partly in elevation illustrating an anchor constructed in accordance with an embodiment of my invention, a second position of the device being indicated by broken lines;

Figure 2 is a view similar to Figure 1 showing the device in locked position;

Figure 3 is a view in top plan of the device as illustrated in Figure 1;

v Figure 4 is a view in perspective illustrating in detail the mounting of a locking arm, the various parts being separated;

Figure 5 is a view partly in section and partly in elevation illustrating an anchor constructed in accordance with a further embodiment of my invention, a second position being indicated by broken lines;

' Figure 6 is an enlarged fragmentary elevational view of the device as illustrated in Figure 5;

Figure 7 is a view in top plan of the device as disclosed in Figure 5.

As illustrated in Figures 1 to 4, my improved anchor comprises a plate 1 of requisite dimensions and which is provided therearound with the outstanding lugs 2 equidistantly spaced and herein disclosed as four in number. Pivotally engaged with each of the lugs at a predetermined point intermediate the ends thereof is an elongated arm 3 sigmoidal in form. To the axial center of the plate 1 is secured auend portion ,,of a rod 4- of desired length.

My improved anchor is adapted to he placed within a suitably formedhole and as it is forced inwardly of such hole by pressure on the rod 4, the arms 3 will assume a substantially vertical position. When the bottom of the hole is reached sufficient pressure is imposed upon the rod 4 to cause the upper ends of the arms 3 to swing outwardly due to the contact of the lower ends of said arms with the bottom of the hole, and which action is further facilitated as the curvature of the lower portions of said arms is inwardly of the plate 1. This action will cause the upper ends of the arms 3 to engage against the side walls of the hole and when pull is imposed upon the rod 4, said arms will have a tendency to straighten out and penetrate the walls of the hole and thereby assure an effective locking of the hook within the hole. This latter movement of the arms 3 is limited by contact of the lower or inner portions of the arms 3 with the under surface of the plate.

The embodiment of my invention as illustrated in Figure 5 is substantially the same as disclosed in the first embodiment herein set forth except that the outer or upper ends of the arms 3 have secured thereto the arcuate cross heads or members 5 disposed in a plane substantially parallel to the flat faces of the plate 1. In this embodiment of the invention the cross heads 5 cut into the wall of the opening when the lower ends of the arms 3 are forced against the bottom of the holes and when pull is imposed upon the rod 4 these cross heads act as wedges effectively locking the anchor in applied position. These cross heads 5 are each preferably substantially one-quarter of a circle.

From the foregoing description it is thought to be obvious that an anchor con structed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter claimed.

I claim 1. An anchor of the class described comprising a plate, a rod secured to the central portion of the plate, arms pivotally engaged intermediate their ends to the peripheral portion of the plate, each of said arms having its lower or inner end portion disposed to underlie the plate.

2. An anchor of the class described comprising a plate, a rod secured to the central portion of the plate, arms pivotally engaged intermediate their ends to the peripheral portion of the plate, each of said arms having its lower or inner end portion disposed to underlie the plate, each of said arms being sigmoidal in form.

3. An anchor of the class described comprising a plate, a rod secured to the central portion of the plate, arms pivotallyengaged intermediate their ends to the peripheral portion of the plate, each of said arms having its lower or inner end portion disposed to underlie the plate, said arms being equidise tantly spaced around the plate.

In testimony whereof I hereunto atlix my signature.

CHARLES B. SCOT T.
