UNITED STATES ALBERT B. CHANCE, or CENTRALIA, mrssounr.
EYE STRUCTURE.
Application filed May 15,
My invention relates to eye structures for anchor rods, guy rods, eye bolts, or other rods or members, used in conjunction with and as terminal attachments for strain members such as wires, strands, stranded ropes or cables, etc.
The principal object of my present inven tion is, to provide improvements in the eye structure set forth in my United States Let ters Patent No. 1,373,223, dated March 29, 1921, on anchor-rod eye, enabling such structure to better withstand rough usage and the effects of extraordinary driving as when an anchor rod of which the eye structure is a part is driven into very hard earth or into earth filled with stones. Other objects will be apparent from the following specification. L
On the accompanying sheet of drawings, Figure 1 is a side elevation of an anchor rod provided with the improved eye structure of this presentinvention; Fig. 2 is a side elevation of the eye structure of Fig. 1, and a portion of the anchor rod, looking in the direction of arrow B with respect to Fig. 1; Fig. 3 is a top end view of the eye structure of Fig. 1; and Fig. 4 is a cross-sectional view of the eye structure of Fig. 1, taken on plane X-X of Fig. 1. Like characters refer to like parts in the several figures.
In the drawings, 11 represents an anchor rod, which is preferably provided with a pointed end portion 12 adapted to be driven into the earth and to co-operate with a suitable anchor plate, not shown, for guying telephone, telegraph, or other poles, smoke stacks, etc. The member 11 may, in certain instances, be apart of other devices besides anchor rods. The top end of the rod 11 is provided with my improved eye structure, preferably as shown.
The eye proper is shown at 13, and the thimble portion is shown at 14. The thimble portion 14 is preferably horseshoeshaped in longitudinal extent, as shown in Fig. 2, the horseshoe-shaped groove 14 being substantially semicircular in cross-section. It will be readily understood that in use, the guy strand or strain member, not shown, extends through the opening 13 of the eye and lies in the horseshoe-shaped semicircular' groove 14 of the thimble portion, the said guy strand or strain member being generally held in place in the groove 14 by means of a suitable clamp as well understood. The semicircular cross-section of the groove 1924. Serial No. 713,566.
14 of the thimble portion provides a. semicircular retaining wall for the guy strand or strain member, which wall conforms to a cylindrical stranded rope or cable and thereby supports or holds such ropeor cable in its cylindrical form and thus prevents it from flattening when it is put under a ten sronal stress. This keeps the load equally distributed among the several strands of the stranded rope or cable and thereby greatly increases the holding power of the stranded rope or cable as a whole, over where it be comes flattened or bent out of shape when subjected to a tensional stress.
The thimble portion 14 entirely takes the place of separate thimbles heretofore used in connection with anchor rod eye structures and other strand-holding devices, and provides a rigid, large, smooth bend for the guystrand or strain member to pull against, which protects such strand or strain member from the usual injury received when pulllng against the ordinary small eye structure without a thimble.
To enable the improved eye structure of this invention to better withstand rough usage and the efi'ects of extraordinary driving as when the anchor rod 11 is driven into very hard earth or into earth filled with stones, I make the top end of the eye structure slightly convex but substantially flat, as shown at 15, so as to'provide a broad driving surface; and the cross-section of the eye structure on each side of the opening 13 substantially triangular, as shown in F ig. 4, so as to provide stiffening corner portions 16, 17, 18, 19, 20, .21; and the side portions of the eye structure at 22 22, convex; and the portions of the eye structure at 23 23, and 24 24, and the rod 11 at 25 25, thicker than in m aforesaid Patent N 0. 1,373,223. These rein orced portions co-operate to stiffen the eye structure throughout, in various respects, and to guard against injury to the eye and the thimble portion, from rough usage and extraordinary driving.
The whole eye structure is preferably drop-forged to shape from material upset from the end of the rod 11, but it may be made in other manners without departing from my invention. Drop-forging is avery cheap and substantial method of making my improved eye structure.
The design of the eye structure illustrated in this application forms the subject-matter of my United States design patent application Serial No. D 5225, filed Feb. 20, 1923, for design for eye structures.
What I claim as my invention is: An anchor rod having an integral end por- 8 tion thereof formed to provide an eye and a horseshoe-shaped groove extending through the eye and projecting from opposite sides thereof to form a curved bearing of increased perimeter for a strain member, :the 10 said groove bein substantially semicircular in cross-section, t e endof the eye structure being sli htly convex but substantially flat to provi e a broad substantially flat driving surface, and the cross-section of the eye structure on each side of the eye proper being substantially triangular to provide stiffemng corner portions.
As inventor of the foregoing I hereunto subscribe my name, this 28 day of April, 1924.
ALBERT B. CHANCE.
