This invention relates to a new and useful .improvement5 in ground anchors such as are employed in connection with rods to which ropes, cables, etc., may be connected. In using ground anchors of the type here-l in contemplated, an opening, such as indicated at A in the drawing, is preferably formed in the ground by a posthole digger or other implement'l and at an angle, as shown. The guy rod4 B is then driven through the ground so that its innerthreaded end projects into the opening A, as shown in Figure, 1, afterA which the ground anchor is engaged with the threaded end of the guy rod and said 'guy'rod turned so as to seat its threaded end into the anchor. The guy rod B may have an eye C formed on its outer end, to which eye is intended to be secured the end of the cable or rope to beanchored.

y In the drawings, 1 indicates the body portion of the ground anchor which is preferably formed with an 'upper convex surface,

' above which extend ribs 2, the height of said ribs increasing towards the center of the anchor where they are conjoined to the ribs 3 and 4, which, with the web wall 5 forms a boxlike structure. y

7 indicates a pivot pin passing through this boxlike'structure, on which are Pivotally mounted jaws 8, said jaws having Haring walls 9. at their .outer ends and registering semicylindrical threaded openings 10 in their adjacent faces- The construction'as above described is disclosed in my companion application filed April 22, 1922, SerialuNo. 556,276.

My present invention contemplates ftheuse of a separate nut into which the lowerend of a guy rod may be turned, instead of securing said threaded end of the lguy rod into a threaded opening formed in t e body portion of the anchor, as disclosed in my aforesaid application. Guy rods are manu- The resultis that anut or threaded opening ANCHOR.

factured with threads Y onV their end'shpro'- duced by different methods. Sonie. guy rods have' their threadsproduced by a 'roller action, while thcltln'eads are cut on other rods.-

which-is designed lwith a rod that'has a. rolled thread is not adapted to receive a rod with a cut thread, and vice versa. f I, therefore, propose to provide a pocket or seat on the underside of the body of the anchor, preferably formed by the walls '13 at the junction of the diagonally arranged r'ein forcing ribs 12, said walls' 13 forming a pocket either square or hexagonal depending upon the shape of the'nut it receives lip 14. Y

15 indicates a nut designed 'to be seated in the pocket, said nut being threaded correspondingly to the threads on the anchor rod with which it is to' be used,i. e.,.having rolled or cut threads as .the/case may be. After the nut is in position,'the lipslll are bent or peened over to hold the nut in place.

I prefer to thread the semicircular openings 10 in the pivotal-jaws after the nut 15 is placed in position using the threaded opening in nut 15 as a-guide for'the tap which forms the threaded openings 10 1n the jaws, thus insuring correct registration of the threaded openings 10 and the threadedv opening in the nut 15. Y

One end of the body provided with-perforations 16 and al notch 17 for use in connection with a positioning implement 18 which for-'ms no part of my present invention However, I will state that after the hole A is dug and the guy rod B is arranged in position, asv indicated, the anchor iS introduced into the opening A by the positioning implement 18 (Figure 1)', the

operatoil forcing the anchor upon the end of the rod until the threaded portion of the rod is forced between the spring held ,jaws

and the .threads of the rod engage the selnicylindrical registering opepi-ngs in the spring held jaws. f Whensuch engagement is ef.

.fected, the rod'18 is' disengaged fromthe ground anchoru; AThe-couvergingxlribs 2 will help guide the end of rod B jaws .and into 'the recess 'formed by the overhanging shelf. A

The y rod having been engagedxbej 'io and each wall 13 being provided with a thin of the' anchor is I tween the into the-threaded opening in the nut, thus drawn. and the anchor may be left in the ground, or may be dug up, if desired.

The boxlikestructure which houses in the movable-jaws and their spring, serves to protect these moving' parts from the entrance of dirt or other foreign particles which might interfere with their operation at the time that the ground anchor is being introduced into position on the guy rod. After i he guy rod is engaged with the movable jaws, then dirt packed behind said jaws and in the space between the jaws andthe housing serves to hold said jaws fixed, and, hence, isnot objectionable.

When the rod is screwed into the anchor, its threads pass from engagement with the threads offthe movable jaws, into engagement with the threads-in the opening in the nut, and, hence, the rod has a solid threaded engagement with Vsaid nut and `said anchor plate. It is obvious that the rod may be unscrewed from the plate at any time even though the anchor plate per se should be abandoned.

What I claim is 1. In a ground anchor, a body ortion, a

nut secured thereto, and" -leirib e means.-

mounted on the body for receiving and holding a guy rod in a predetermined position to engage said nut.

2. In a ground anchor, a body, a` nut secured thereon and resilient means for guiding a threaded guy rod, moved transversely of the axis of said nut, into. proper .relation to said nut whereby threaded enjaws for receiving and guiding said rod. 4. A ground anchor c'ompr' ing a` body portionvhaving a boxlike ho sing on its upper side, a pair fof/spring held jaws 'l arranged in said housing for engagement with a guy'rod, the .contiguous faces voisaid jaws being provided with registering threaded semicylindrical recesses,^` and aV nut arranged in, position on said'body portion and provided with a threaded opening forA receiving said guy rod. Y

5. In combination, a ground anchor comprising an anchor plate, a nut having threaded openings and iixedly secured in position on said plate, a guy rod adapted for Y threaded engagement with and disengagement vfroml said nut, and means for guiding said guy rod intoposition' to engage the threaded opening in `said nut.v

` In testimony whereof I`herentoaiix my signature this 28th day of June, v1922.
