' 2 Claims. (Cl. 24-1123) Thisinvention relates ,to improvements in eye nuts, and particularly to an improved apertured nut which is adapted to be used as a terminal eye forthe rod of a ground anchor or the like.

- Such a device is usually designated'as an anchor eye, when used as a connection between an anchor rod and one-or more guys. The anchor eyes heretofore used consist, usually, of one end of the anchor rod, turned upon itself to form a .0 loop through which the guy or cable extends.

the rod itself is usuallyof small diameter, this practice causes a sharp bend of the cable, and a restricted area of contact where it engages the loop-formed eye. In practice, this disadvantage 115 has been remedied, to a certain extent, by the use of an additional element, usually referred to as a thimble, which in effect increases the radius of the bend of that portion of the guy or cable which extends through the loop. An object of the present invention is attained in a device which offers all of the advantages, of the thimble, and dispenses entirely with its use, as a separate ele' ment.

In connection with anchor installations for pole lines and the like, it is sometimes necessary to attach two or more guys to the same anchor. rod. In such cases, the usual practice is to enlarge the eye to accommodate the added number of guys; This practice results in friction between the guys, with a resultant wearing off of their protecting surfaces, such as galvanizing, which in turn results in premature rusting. Furthermore, when using a single guy in an enlarged opening, the tendency is for the guy to occupy one side of the opening, and thus to bend the rod below the eye.

These disadvantages are, likewise, eliminated by the use of my improveddevice.

A further object is an improved construction and location of the eye openings, facilitating the use of two or more guys with a single eye, the eye A still further object is to form an anchor eyehaving the recited novel features, and adapted to serve, with the anchor rod, as a means for positioning an anchor wrench, during the driving or setting of the anchor.

Further objects and advantages of the invention will appear from the following detailed description and the accompanying drawing, in which:

Fig. 1 is an elevation of a preferred form of anchor eye,.sho wing. two guys attached in deadend relation thereto; Fig.2 is a plan View of the anchor eye; Fig. 3 is a sectionalelevation along line 33 in Fig. 2; Fig. 4 is a sectional elevation along line P4 in Fig. 2.

Referring by numerals to the drawing, the i1nproved form of anchor eye is shown as being substantially of cylindrical shape, but may be made in any form embodying the novel constructional features hereinafter described. One end of the anchor eye may be provided with a tapped hole 11 for threaded engagement with an anchor rod, of any suitable form, a portion of which is indicated by reference numeral 16. The threaded end of the anchor eye is formed, preferably, with a tapered portion 12, terminating in an annular shoulderl3. When using the eye with a wrench .or other tool for driving the anchor, the shoulder .13 is useful for bearing against the tool to retain it, in engagement with the anchor.

The anchor eye may be provided with openings 14 or the eyes proper, adapted, when the eye is in service,to receive the guys or cables 1'7. The present invention relates, in part, to these openings. which are preferably formed of arcuate section as shown at 15, to provide a substantial area of contact with a sufficient radius, so that the cable loop may be formed without injury to its strands. When two such openings are provided, the openings 1e are preferably disposed at right angles to each other, as appears from Figs. 3 and 4. 9

The improved construction of anchor eye offers a number of advantages over the anchor eyes heretofore used. The provision of arcuate openings of substantial area obviates the necessity of thimbles, heretofore employed as separate ele- 5 ments, in anchor installations, and thereby reduces to this extent the expense and labor incident to employment of an extra member for this purpose. My construction further provides a seat for the cable or guy, which has a contact bearing area extending around the entire inner surface of the arcuate opening and which has a trend along the cable, thereby distributing the strain over a greater area than is possible in older types of anchor eyes, without the use of a separate 9 thimble or the like.

With an anchor eye embodying the present improvements it will be seen that the body of the device serves to keep the cable member, separated substantially; at all times, from its conjugate or the dead end, so as to prevent chafing or wear between adjacent parts of the dead-ended cable. With constructions heretofore prevailing, this result is not possible, even with the use of a thimble.

When using more than one guy, the recited feature of disposing the eye openings at right angles to each other, results in an application of the tension of the several guys, along the axis of the anchor rod, instead of permitting the ofi-side pull, incident to eyes of the heretofore used sort to accommodate two or more cables. Such an off-side pull will, obviously, result in a tendency to bend the rod. In the example shown, the guys are pulled through individual openings in the body of the eye or nut, and no interference is possible between the several dead-ends. With this novel construction, guy clamps such as are indicated at 18 can be installed and bolted up without interference with each other, as the clamp on one dead end, will naturally be disposed within the loop of the other guy.

I claim as my invention:

1. A one piece anchor eye element comprising an elongate body, axially spaced transverse passages extending through the body forming a pair of cable seats, the cable seats being curved toward the outer end of the eye and disposed substantially the body of said-element, each seat being of arcuate section, directed toward the end of said element opposite the rod-engaging portion, and adapted to engage a substantial area of a deadended cable, said cable seats being disposed substantially at, a right angle to each other, and extending across the element; means adjacent each of said seats, adapted to serve as a spacer between each cable and its dead end, means forming a transverse partition between said cable seats, and an annular projection on the body of said element adapted to coact with the anchor rod, to position an anchor wrench.
