This invention relates to a guy wire protector having a novel universal clamping arrangement, and more particularly relates to such a protector including a connecting means which may be optionally clamped either to an anchor rod or to a guy wire.

Guy wire protectors are mounted about guy wire assemblies used for supporting poles, trees or other structures in an upright position. These protectors usually conceal the connections between a guy wire and an anchor rod which is usually driven into the ground, and they ac cordingly incorporate connecting means for attaching them at two portions thereof to the guy wire assemblies. The upper clamp of the protector, which usually incorporates an elongated open-sided sleeve, connects to the guy wire; and the lower clamp usually is secured to the anchor rod which is secured within the ground. However, in some instances, it is desirable to clamp the lower portion of the protector to the guy wire instead of to the rod. Since anchor rods range, for example, from /2 inch to 1% inches in diameter and guy wires range, for example from /2 inch to A inch in diameter, it is diflicult to provide a clamping arrangement which will operate dependably throughout such a wide range of sizes and shapes. Ordinary protectors, therefore, can be clamped to anchor rods satisfactorily but cannot be eifectively clamped directly upon guy wires, particularly those of a smaller diameter.

An object of this invention is to provide a simple and economical guy wire protector which can be optionally clamped upon anchor rods or guy wires of widely varying size.

In accordance with this invention a row of holes is disposed along the length of the sleeve of a guy Wire protector near its lower end and remote and substantially parallel to the sleeves longitudinal centerline. A bolt is inserted through one of these holes and through a hole in an elongated clamping plate. The length of the clamping plate and the location of the holes are arranged to cause the clamping plate when its length is oriented substantially perpendicularly to the longitudinal centerline of the sleeve to overlie the central portion of the sleeves interior suficiently to clamp an anchor rod within it. Furthermore, the width of the clamping plate is narrow enough to clamp a guy wire within the sleeve when clamping plate is oriented with its length disposed substantially parallel to the longitudinal centerline of the sleeve.

In accordance with one form of this invention several rows of holes are disposed along the length of the sleeve of the protector. One of these rows is disposed approximately along the longitudinal centerline of the sleeve, and another of these rows is positioned remote or displaced and parallel to this centerline. A clamping plate includes two threaded holes. One of these holes is positioned approximately upon the longitudinal centerline of the plate, and the other of these holes is positioned adjacent one of the sides of the plate. A clamping bolt is inserted through one of the holes in the elongated sleeve with its head protruding outside. This bolt is engaged Within one of the threaded holes in the plate for optionally clamping the protector to an anchor or guy wire. When this bolt is respectively inserted through and engaged within holes disposed along the longitudinal centerlines of the sleeve and plate, a guy wire is easily clamped between the plate and the sleeve. When the bolt is inserted through one of the holes displaced from the centerline of the sleeve and engaged within the hole near the side of the plate, the relatively long overhang of the plate facilitates the clamping of an anchor rod between the sleeve and plate.

A projection may be extended inwardly, for example, from a shorter side of the clamping plate, which is remote from the hole for clamping anchor rods, to help confine an anchor rod between the plate and the sleeve. In this condition the plate is positioned within the sleeve its projection extending towards the sleeve. When the plate is used for clamping guy wires, the plate is turned over with this projection extending outwardly away from the sleeve and with its shorter side lying across the inner curve of the sleeve. This permits the plate to be positioned as close as possible within the inside of the sleeve to facilitate the clamping of the relatively smaller guy wires. Furthermore, the head of the bolt may be laterally extended to maintain it directed away from the center of the sleeve when it is used for clamping anchor rods.

FIGS. 14 and 15 are cross-sectional views taken through an embodiment of this invention utilizing the sleeve shown in FIG. 11 in two dilferent modes of installation.

The two optional modes of installation of a guy wire protector 10 which is an embodiment of this invention are shown in FIGS. 1 and 2 together with respective

crosssectional views

3 and 4. Specific reference characters incorporating letter sufiixes are, accordingly, used in FIGS. 1-4 for parts designated by general reference numorals in FIGS. 5-8.

In FIG. 1 is shown a guy wire protector 10A which is, for example, installed upon a guy wire assembly 12A which includes a guy wire 14A, anchor rod 16A which is secured within the ground, and a wire-fastening assembly 18A which secures the looped end 20A of guy wire 14A to the eye 22A of rod 16A.

Guy wire protector 10A includes an open-sided elongated sleeve 30A, a top fastening means 32A fastened to the upper end of sleeve 30A for example, by rivets 34A. Top fastening means 32A which is, for example, a book 32 is also shown in more detail in FIGS. 7 and 8 and is 3 fully described in US. Letters Patent 2,264,430, issued December 2, 1941. Sleeve 30A is curved, for example, to approximately a 1 /2 inch radius.

The other means for attaching sleeve 30A to guy, wire assembly 12A is, for example, bottom clamping assembly 36A which includes rows of holes 38A and 40A disposed along the length of sleeve 30A as shown in detail in FIGS. 7 and 8.

Bottom clamping assembly 36 A also includes a bolt 42A which is, for example in FIG. 1, inserted through one of holes 40 parallel and remote from longitudinal centerline 44 of sleeve 30 shown in FIG. 8. FIG. 3 shows in detail the manner in which bolt 42A is inserted through sleeve 30A with its head 46A bearing against the outer surface of sleeve 30A. A lateral extension 48A of head 46A bears against the outer surface 50A of sleeve 30A and directs the shank 52A of bolt 42A away from the center of the interior of sleeve 30A. Shank 52A of bolt 42A is engaged within threaded hole 54A which is disposed adjacent a shorter side 56A of clamping plate 58A shown in detail in FIGS. and 6. Plate 58A in FIGS. 1 and 3 is oriented in a direction which positions projection 60A, which is, for example, formed at the end of clamping plate 58A remote from hole 54A, towards sleeve 3 0A. This projection 60A is, for example, formed by forging the end of plate 58A.

In FIG. 3 anchor rod 16A is clamped between sleeve 30A and plate 58A with projection 60A turned inwardly to help maintain rod 16A confined bet-ween clamp 58A and the inner surface 62A of sleeve 30A, Plate 58A is, for example, approximately 2 inches long and 1% inches wide which perm-its anchor rods ranging, for example, from /2 inch to 1% inches in diameters to be securely clamped.

In FIGS. 2 and 4 is shown another mode of connection of lower clamping assembly 36 which is specifically designated 36B to distinguish from the 36A mode of connection shown in FIGS. 1 and 3. However, it should be apparent that bottom clamp assembly 36B utilizes exactly the same parts as clamping assembly 36A arranged in a slightly different fashion which is now described in detail.

In FIGS. 2 and 4 clamping assembly 36A is fastened, for example, to the loop 20B of guy wire 14B and shank 52B of bolt 42B is accordingly inserted through one of holes 38 of sleeve 30 which are shown in FIG. 8. Holes 38 are disposed approximately along longitudinal centerline 44 of sleeve 30. Shank 52B accordingly passes through the center of sleeve 30B and, for example, through the center of the loop 20B of guy wire 14B. In this position plate 58B is engaged with bolt 42B by insertion of shank 52B through threaded hole 64B in plate 58B. Hole 64B is approximately disposed along the longitudinal centerline of plate 58B to permit it to be drawn as close as possible within the inner curve of sleeve 30 B. Plate 58B is accordingly turned with its shortest dimension provided, for example, by shorter sides 56B disposed across the inner curve of sleeve 30B and with projection 60 B directed away from inner surface 62B of sleeve 3013 to avoid interference with the clamping of guy wire loop 20B between clamping plate 588 and the inner surface 62B of sleeve 30B.

It is accordingly apparent that one simple assembly including rows of

holes

38 and 40 in sleeve 30, bolt 42 and a clamping plate 58 including threaded

holes

54 and 64 may easily be used in two optional modes of installation to clamp an end of sleeve 30 to either an anchor rod 16 or a guy wire 14. This guy wire, for example, ranges in diameter from Mt inch to /2 inch. Furthermore, the positioning of head 46 of bolt 42 externally of sleeve 30 together with the screw threads in

holes

54 and 64 in clamping plate 58 highly facilitates clamping either to anchor rods or guy wires by simple application of a wrench to the head 46 of bolt 42 which extends outside of sleeve 30.

It should also be apparent that the mode of connection of clamping assembly 36 shown in FIGS. 2 and 4 and designated by 3 63 may be used to clamp to single strands of guy wires 14 as Well as to the double strands provided by loop 20 as shown in FIGS. 2 and 4. As is also shown in FIGS. 3, 4 and 8, the sides of elongated sle ve 30 are bent inwardly to form inwardly-directed flanges 66 to eliminate sharp edges on the sides of sleeve 30 and to help enclose guy wire assemblies 12 and clamping assembly 36.

In FIG. 9 is shown a protector sleeve 30a which is generally similar to sleeve 30 shown in FIGS. 7 and 8 with the exception that the only two holes 38a are in cluded in the row disposed along the longitudinal centerline of the sleeve because attachment at this lower end is usually made through one of holes 40a remote from the centerline to an anchor rod. Furthermore hole 82a in clamping plate 58a shown in FIG. 10 is not threaded, and the plate itself is flat without a projection such as 60 shown in FIG. 6. Clamping plate 58a is accordingly secured by means of a nut (not shown) screwed upon the end of bolt 42a (also not shown), and the internal curve of the concave interior of sleeve 30a is sufiicient to retain an anchor rod in position in most conditions of service.

Sleeve 30a shown in FIG. 9 also ditfers from sleeve 30 shown in FIGS. 7 and 8 in that upper clamping means 32a is formed directly of the material of protector sleeve 30:; itself as described in detail in copending application S.N. 35,261, filed June 10, 1960. This form of upper clamp includes a slot 700 through which a guy wire passes into the sleeve. The guy wire is retained against the convex outside end of the sleeve above slot 70a within indented longitudinal channel 72a, and it is held inside the sleeve below slot 7 011 within protruding channel 74a. Furthermore, a tab 76 locks the guy wire in place by having its hook-shaped end 78a bent over the guy wire to securely retain it.

In FIGS. 11-15 is shown another embodiment of this invention including protector sleeve 30b shown in FIG. 11 which has an upper attaching means 3212 which is for example similar to 32a of FIG. 9. It also includes a row of holes 40b disposed remote and substantially parallel to longitudinal centerline 44b. In FIGS. 12 and 13 is shown a clamping plate 58b substantially similar in form to plate 58 shown in FIGS. 5 and 6; however it only includes one hole 82b, which is for example, disposed adjacent a shorter side 56b of plate 58b and substantially upon the longitudinal centerline 84b. Hole 82b is threaded in a similar manner to

holes

54 and 64 shown in FIGS. 5 and 6.

FIGS. 14 and 15 show the mode of coimection of sleeve 30b to a guy wire and anchor rod. In these figures terminal sufiixes A and B are used to respectively designate the modes of installation corresponding to those shown in FIGS. 3 and 4 respectively clamped to anchor rod and guy wire.

FIG. 14 shows protector sleeve 30bA together with a bolt 42bA clamping an anchor bolt 16bA within a protector sleeve 3011A. The condition shown in FIG. 14 is quite similar to that of FIG. 3 because a roW of holes 40bA remote from the centerline are utilized for clamping an anchor rod 16bA within the interior of sleeve 30bA. However, FIG. 15 is quite different from FIG. 4 because the same hole 40bB is utilized for clamping a guy wire 20bB within the interior of sleeve 30bB. Even though guy wire 20bB is clamped at a position somewhat displaced from the longitudinal centerline of sleeve 30bB, this does not prevent a reasonably satisfactory installation from being accomplished because the displacement is not sufiicient to unduly expose the guy wire.

This application is a continuation-in-part of prior patent application Serial Number 797,442, filed March 5, 1959, now abandoned.
