YUNITED STATES PATENT OFFICE.

. ANCHOR.

Application filed October 5, 1926. serial no. 139,695.

This invention relates to certain improvements in anchors and it is an object of the invention to provide a device of thiskind for use in connection with guide lines or the like for telegraph poles, etc, and wherein means is provided to effectively apply the anchor in working position;

The invention also has for an object to provide an anchor comprising a plate carrying a plurality of pivotally supported looking arms together with means for causing said arms to extend into desired 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, I will now proceed to de-' scribe the same with reference to the accompanying drawing, wherein Figure 1 is a view in top plan of an anchor constructed in accordance with an embodiment of my invention, the rod being shown in section and the locking arms extended;

Figure 2 is a view in side elevation of the device as illustrated in Figure 1 with the arms in their raised or inoperative position;

Figure 3 is a view partly in side elevation and partly in section illustrating the arms in extended or locking position;

Figure 4- is a view in top plan of the plate fixed to the rod.

As disclosed in the accompanying drawing, 1 denotes a circular plate of requisite diameter and which is provided therearound in its peripheral portion with a series of equidistantly spaced open slots 2, the side margins of which being defined by depending lugs 3.

Pivotally supported between each pair of lugs 3 by the bolt 4 or the like is an end portion of an elongated arm 5 disposed on a predetermined incline and which extends above the plate 1. The pivoted end portion of the arm 5 is provided with a tail extension 6 extending inwardly of the plate 1.

The contact of the tail extension 6 with the under surface of the plate 1 limits the extentof outward and downward swinging movement of the arm 5.

At its axial center the plate 1 is provided with an opening 7 through which is freely directed an elongated rod 8. This rod 8' has its lower end in threaded engagement with the axial center of a second plate 9 of a diameter less than that of the plate 1 and which is adapted to have contactwith the tail extensions 6 to cause the arms 5 to swing outwardly into working or locking position.

In practice, my improved anchor is placed within a suitably formed hole and when in desired position the contact of the tail extensions 6 with the plate 9 will cause the arms 5 to swing outwardly and downwardly into contact with the wall of the hole. Uponrequisite pull being imposed upon the rod 8 the arms 5 will penetrate the wall of the hole and thereby assure an effective locking of the anchor.

The upper surface of the plate 9 has disposed substantially radially thereon a ridge 10 which is adapted to receive a tail extension 6 to hold the plate 9 against rotation when it is desired to unscrew or free the rod 8 from such plate 9. This is of advantage when it is desired to reclaim the rod when discontinuing the use of the anchor.

From the foregoing description it is thought to be obvious that an anchor constructed 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 rod, a plate freely slidable thereon, arms pivotally engaged with the peripheral portion of the plate, each of said arms having a tail extension extending inwardly of the plate, and a second plate carried by the rod below the first named plate and tail extensions for contact with such extensions to swing the arms outwardly into working position.

2. An anchor of the class described comprising a rod, a plate freely slidable thereon, arms pivotally engaged with the peripheral portion of the plate, each of said arms hav- 4 'ing with a tail extension to hold the second plate against rotation to permit unscrewing of the rod from the second plate.

An anchor of the class described comprising a rod, a plate freely slidable there on, arms pivotally engaged with the peripheral portion of the plate each of said arms having a tail extension extending inwardly of the plate, a second. plate threaded upon the rod below the first named plate and tail extensions for contact with such extensions to swing the arms outwardly into Working position, said second plate having means coacting with a tail extension to hold the second plate against rotation to permit unscrewing oi the rod from the second plate, said means comprising a ridge in a face of the second plate opposed to the first plate to receive a tail extension.

In testimony whereof I hereunto afiix my signature.
