ANCHOR ROD.

Application filed February 24, 182?; Serial No. l?0,722.

My invention relates to anchor, guy or stress rods'and pertains more particularly to improvements in that type of such devices of such nature, that the friction between. the

rod and the strand used therewith is reduced in order that the tensioning of guys oranchors may be facilitated; that rubbing 1 1 tion is eliminated between the strand an rod to prevent scoring and destruction of the galvanized coating usually placed on such rods and strand; and tl'iat the strand is guided and constrained to a'position which Simplifies and expedites the clamping operation.

Anchor or stress rods as heretofore used are provided with an eye in one extremity through'which the strand is threaded. -VFhen an external force is placed on the free end or the strand and it is pulled through the eye in the operation of tensioning the guy or anchor, the galvanized coating on the strand and on the inner surface of the eye is almost invariably stripped oil, leaving the iron or steel surface unprotected and exposed and thus subject to rapid oxidization aggrw vated by electrochemical action due to the presence of the dissimilar metals, iron or steel and zinc. Further the necessity for manually holding the two lines of strand parallel to receive a clamp is difficult and occasions delay.

In my improved device I provide a sheave attached to the rod and strand guides, so located with respect to the sheave that as the tensioning "force is placed onthe strand the strand rotatesthe sheave to eliminate rub-. hing friction while the guides constrain the two lines of strand into the proper position to readily receive the clamp. I

Other objects and uses will be apparent from the following description and drawings in which like reference numerals designate corresponding parts throughout and in which:

The embodiment of ray/device illustrated in Figs. 1-4 inclusive comprises a'rod 1, one extremity of which may be threaded and provided with nut 2 as shown whereby the de vice may be attached to an anchor block or other s pport. The other extremity of the rod 1 is termed to have a flattened portion 8 in which are formed two parallel groves a and 5, of substantially semi-circular cross-section. The longitudinal axes of the grooves are in one plane and are parallel to the longitudinal axis of the rod 1. A. studl l is provided on r the flattened portion of the rod and between the cylindrical portion of the rod and the guides d and 5. The aXis of this stud is substantially perpendicular to and in the same plane as the longitudinal axis of the rod. The stud let carries a sheave or thimbl'e 13 adapted to rotate thereon, and be retained thereby. The upper extremity oi the stud is formed after the thimble is placed in position thereon, to have a retaining lip, as shown in Fig. 1. Fig. 4 illustrates the formof the upper extremity of the stud 14 before there- 'taining lip is formed. The guides at and 5 are so spaced with respect to each other and the diameter of the thimble 13 and are so located with respect to the normal plane of rotation ofthe thimble 18 that as the strand is tensioned the two lines of strand naturally fall into the grooves 4t and 5 and are constrained thereby into parallel relation to receive a detachable member 15 which is pro vided with parallel grooves similar to and spacedexactly the same as the grooves and 5, and which when held in place by the bolts 6, 7 and 8 to the flattened portion 3 forms a clamp for the strand 12 to maintain the tension on the strand and rod. The strand is rent, FFHQEQ constrained by the guides 4 and 5, as hitherto mentioned, because the height of the stud on the stud, when tensioning force is placed on the strand.

The particular embodiment shown in Figs. 5 and 7 com arises a rod 21, one extremity of which is formed to provide ttened and broadened portion provided with pair of oppo'. ly disposed hooks.

p and 2? of substantially semi-circular form. A stud 23 is located with its axis substantiall Y aernezr.

dioular to and in the same plane the longitudinal axis of the rod 21 and is located near the cylindrical portion O1! die rod and between that portion the rod and the hooks my a 1 a o 26 and were 1; is carried and retained by the sliu' and is adapted to rotate ther on. Thus the rand 28 1s tensioned us eliminates the thimhle as rot; rubbing t-iction b rod, wi:

- tion scoring or destruction of the galvanized the strand and further sil'nplilies facilitates and expedites the installation oi anchors or gu s.

i, J While I have illustrated and described two coating; of

embodiments of my device it should be clearly understood that l may make numerous modifications in the details thereof without departing from the spirit or narrowing the scope of my invention.

What I claim is 1. An anchor rod, one extremity of which is formed to have a flattened portion, a stud carried by said flattened portion and located near the cylindrical portion o'l said rod with its axis substantially perpendicular to the longitudinal axis of said rod, thimble carried andret-ained by said st-urh strand guiding and constraining means provided in the flattened portion of said rod, and a detachable member adapted to be secured to said guiding means to form with said guiding means a strand clamp.

2. An anchor rod, a portion of one 8X- tremity of which is flattened and provided with a pair of parallel grooves the axes of which are in one plane and are parallel with the longitudinal axis of said rod. a stud located between the cylindrical portion of said rod and said grooves and with its axis perpendicular to and in the same plane as the longitudinal axis of said rod, a thimble carried and retained by said stud and adapted to rotate thereon with its axis off rotation normally in the plane or the axes of said grooves and a detachable member adapted to be secured to that part of said flattened portion which bears said grooves.
