The first segment has a stop lug and the other segment is at times rotatable to facilitate engagement ofa guy wire between the segments, but can be returned to opposing registering relationship with the first segment by moving it into abutment with the stop lug.

22 Claims, 5 Drawing Figures PATENTED A l975 GUY WIRE PROTECTOR This invention relates to guy wire guard devices and, more particulary, to protective sleeve assemblies for receiving guy wires associated with telephone poles, utility poles, and the like.

A main object of the invention is to provide a novel and improved guy wire protective sleeve assembly of the type provided with clamping means for clampingly engaging one or more guy wires extending through the main sleeve portion of the assembly, the assembly involving relatively simple components, being easy to install, and being insulated against stray electrical currents whereby to minimize electrical hazards.

A further object of the invention is to provide an improved protective sleeve assembly for guy wires associated with telephone poles, utility poles, or the like, the assembly employing relatively inexpensive components, being durable in construction, being arranged so that it can be installed quickly and with a minimum amount of labor, being substantially smooth and protected against electrical hazards from stray currents, and being arranged so that it can be used to receive and clampingly engage either one or two guy wires in accordance with the requirements of the particular installation in which it is employed.

A further object of the invention is to provide an im proved guy wire protective sleeve assembly which includes a pair of cooperating clamping segments, one of which is securely bonded to the inside surface of the main protective sleeve element of the assembly by cement, adhesive, heat fusion or other suitable means to form a unique, permanent, integral clampsleeve unit, and the other of which is at times pivotally extensible so as to facilitate the clamping engagement of the assembly with a guy wire, the bonded segment being provided with stop means so that the rotatable segment can be returned to its registering position relative to the bonded segment, and the segements being clamped together by fastening means which is securely locked and which cannot become rusted to the segments whereby the assembly can be removed as required for maintenance and can be easily reinstalled.

A still further object of the invention is to provide an improved guy wire protective sleeve assembly which will be securely held in its desired protective position surrounding a guy wire and will not become loosened because of vibration or other causes, which can be quickly and easily installed or removed, as required, and which is provided with internal clamping means comprising cooperating clamping segments which are substantially self-aligning and which can be rapidly and securely fastened together in clamping position without requiring the use of special tools or equipment.

Further objects and advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein:

FIG. 1 is a perspective view showing a typical telephone or utility pole provided with stabilizing guy wires and employing protective guy wire sleeve assemblies according to the present invention.

FIG. 2 is an enlarged cross-sectional view taken substantially on the line 2-2 of FIG. 1.

FIG. 3 is a vertical cross-sectional view taken substantially on the line 3-3 of FIG. 2.

FIG. 4 is an enlarged fragmentary cross-sectional view taken substantially on the line 4-4 of FIG. 2.

FIG. 5 is a perspective view showing a pair of cooperating clamping segments employed in the sleeve assembly of FIGS. 1 to 4.

Referring to the drawings, II designates a typical utility or telephone pole which is provided with a plurality of stabilizing inclined guy wires 13 which connect the pole to suitable anchoring means in the ground spaced outwardly adjacent the pole. The inclined guy wires 13 are provided with elongated protective sleeve assemblies 14 constructed in accordance with the present invention.

Each protective guard assembly I4 comprises an elongated main sleeve member 15 which may be of any desirable cross-sectional shape, for example, which may be U-shaped, semi-circular, or, as illustrated in the drawings, may be of circular cross-sectional shape. The sleeve member 15 is of sufficient length and size to adequately receive the associated guy wire 13 to provide a protective covering for the guy wire and its anchoring system. The sleeve member 15 is provided adjacent at least its upper end with means for clamping the sleeve member to the associated guy wire I3 so that the sleeve 15 will be securely held in its desired position in covering relationship to the associated guy wire I3.

The elongated sleeve member I5 is preferably made of suitable insulating material, such as plastic material, or the like. The clamping assembly provided in the upper portion of the sleeve member 15 comprises a first segment 16 rigidly secured inside the upper portion of the sleeve member 15 and a cooperating clamping segment I7 adapted to be clampingly secured in a manner presently to be described to the first segment 16 with the guy wire 13 received therebetween. The clamping members 16 and 17 are preferably made of plastic material having substantially the same physical characteristics as the material employed for the elongated outer sleeve member 15.

As shown in FIG. 5, the clamping member 16 is formed with an arcuate upper surface 18 conforming with the cylindrical inside surface of the sleeve member 15, the surface 18 being further formed with uniformly distributed rectangular recesses 19 which act as reservoirs for cement and thereby insure intimate bonding of the member 16 to the inside surface of the sleeve member 15. The integrity of the bond thus provided is further assured because the sleeve member 15 and the clamping member 16 are preferably made of the same insulating material and thus have the same coefi'icient of expansion. Thus, in securing the member 16 to the sleeve 15, the surface 18 is throughly coated with suitable adhesive bonding material and the member 16 is held against the inside surface of the sleeve member I5 substantially as illustrated in FIG. 4, namely, near an end of the sleeve. Thus, when thus bonded, the clamping element 16 becomes substantially integrally united to the sleeve in a transversely extending position therein as is illustrated in FIGS. 2 and 4.

The member 16 is formed with three countersunk apertures 20 which register with three apertures 21 provided in the sleeve member 15. The bottom portion of the clamping member 16, as viewed in FIG. 5, is formed with three longitudinally extending spaced grooves 22, and the transverse marginal portion of the member 16 is formed with a plate-like depending lug 23, as viewed in FIG. 5.

The cooperating clamping member 17 comprises a block of plastic material, preferably similar to the material employed for the clamping member 16, and is likewise formed with three spaced longitudinally extending grooves 24 which are registrable with the grooves 22 of the member 16 in opposing relationship thereto, as will be presently described. The clamping member 17 preferably has sloping end surfaces 25 and 26, as shown in FIG. 2, converging toward the flat bottom surface 27 of member 17. The member 17 is formed in the grooves 24 with tapered tapped holes 28 which are registrable with the countersunk holes 20 of the fixed clamping block 16 when the member 17 is in the opposing relationship with block 16 shown in FIGS. 2 and 4.

The member 17 is provided with a rounded corner 29 to allow member 17 to be at times swung away from parallelism with the fixed clamping block member 16, for example, to the dotted view position shown in FIG. 3, to facilitate the positioning of the guy wire 13 between the clamping blocks. In the typical embodiment illustrated in the drawings, a single guy wire 13 is adapted to be received between the central grooves 22 and 24 of the clamping block members 16 and 17, and threaded clamping screws 30 are engageable through the apertures 21, 20 on opposite sides of the guy wire 13 and are threadedly engageable with the correspondingly located tapered tapped openings 28 of clamping block 17. The heads of the clamping screws are receivable in the counterbores 20, as shown in dotted view in FIG. 2, whereby the assembly 14 has a continuously smooth outer contour.

It will be understood that the guard sleeve 15 is first prepared by cementing the clamping member 16 therein in the manner above described with the countersunk holes 20 in registry with the apertures 21 of the sleeve and the clamping block 16 arranged in the manner illustrated in FIG. 4. The other clamping block 17 may then be connected to the fixed clamping block 16 by employing a headed screw 30 engaged in the countersunk opening 20 of block 16 remote from the stop lug 23. The clamping block 17 may be positioned in a direction substantially parallel to the sleeve 15 under these conditions, for example, may have the dotted view position thereof shown in FIG. 3 to facilitate the adjustment of the sleeve 15 on the guy wire 13. When the guard sleeve 15 has been adjusted to its desired position, for example, the position thereof shown in FIG. 1, the block 17 may be rotated counterclockwise from the position thereof shown in dotted view in FIG. 3 until it engages the stop lug 23, thereby bringing the remaining holes 28 of block 17 into registry with the remaining countersunk holes 20 of the fixed clamping block 16. Under these conditions, the middle grooves 22 and 24 of blocks 16 and 17 will receive the guy wire 13. Another headed screw 30 may then be engaged through the registering holes 28 and 20 on the side of the guy wire 13 opposite to the first-employed screw, and may be threadedly engaged in the tapped opening 28 of block 17 in registry therewith. Both of the screws 30 may then be tightened to clamp the guy wire 13 between the middle grooves 22, 24 of the respective blocks 16 and I7. This clamps the guard assembly 14 to the guy wire 13 in its desired position.

A reverse procedure is employed when it is desired to unclamp the assembly 14 from the guy wire 13.

It will be noted that the tapped holes 28 of block 17 are tapered so as to securely hold the clamping bolts 30 and to minimize the possibility of stripping the threads.

This arrangement eliminates the necessity of using fas' tening nuts or other hardware for holding the clamping member 17 in clamping position. The tapered tapped holes 28 also act to prevent loosening of the clamping bolts 30 under vibration or other severe mechanical condition. Because the clamping block 17 is made of the same material as the outer sleeve 15 and the fixed clamping member 16, there is no possibility of the clamping bolts rusting to the threads of the clamping member 17, as in the case where only metal parts are employed. Thus, this permits easy removal or detachment of the guard assembly from the associated guy wire 13 when it is necessary for maintenance operations to be performed, and likewise facilitates reinstallation of the assembly without requiring any replacement parts.

The provision of the three sets of registrable grooves 24, 22 respectively in the block 17 and the block 16 permits the use of either two bolts to clamp a single guy wire as above described, or one bolt to clamp two guy wires contained within a common guard sleeve 15.

Since the locking members are made of insulating material and the arrangement is such that the clamping bolts are insulated from the guy wire, there is no possibility of conducting stray electrical currents to the clamping bolts. This provides a much safer installation than the conventional arrangements employing allmetal locking members and wherein currents may be conducted from the guy wire to the clamping bolts.

It will be noted further, that the installation of the assembly 14 is relatively simple, since the movable locking member 17 may be pivoted so as to extend out of the upper end of the shell 15, as shown in dotted view in FIG. 3, to thereby facilitate the insertion and positioning of the guy wire 13 in the shell 15. As above mentioned, the stop lug 23 is arranged so as to provide automatic alignment of the holes 20, 28 when the movable clamping block member 17 is swung back against lug 23. Stop lug 23 not only provides such automatic alignment of the bolt holes but also prevents undesired inward pivoting of the clamping block 17.

As will be seen from FIG. 3, the pivotal connection of the member 17 to the fixed block 16 is located so that the member 17 is easily accessible from the upper end of the sleeve 15 and may be manually rotated, as required.

While a specific embodiment of an improved guy wire protective assembly has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claims.
