The lower clamp further has a bottom adapted to be secured to the surface and having first and second bolt head receiving slots, each of which is wider than its respective one of the first and second indentations, the first and second slots each being open at its respective lower clamp end and receiving a respective bolt head and preventing the respective bolt head from rotating.

Abstract: An easily-installable support capable of accommodating a wide variety of fiber optic cables is disclosed. The fiber optic cable support uses a one-piece, variable diameter mechanism for cushioning and spacing the supported cable. The support is also contoured to increase the surface area available to contact a utility pole or other structure and includes one or more cleats or gains which provide additional contact strength by biting into and gripping wooden or similar poles. The support is designed to provide approximately constant compressive pressure to the supported sections of a length of cable and sufficient pressure to avoid the need to apply grit or other loose friction-increasing substances to the cushion interior. Because it is of relatively constant or slowly varying cross-section, the support can be die formed with minimal disruption of the fluid flow within the die.

Abstract: The present invention provides for a cable or rope restraining device which comprises a U-shaped member or U-bolt to engage two saddle clamps. The first saddle clamp is a friction clamp for securing a dead end section of the rope. The second saddle clamp provides a channel for loosely containing a live section of the rope.

Abstract: A safety clamp appliance is disclosed formed of a cable or rope housing having opposed hinged walls for opening to receive a rope and a generally U-shaped cross-section, the housing interior being adapted with a rope slide to receive a safety rope, a brake lever having a pivot point, a brake surface and a handle for attachment to a climber's belt. The brake lever is pivotally mounted in the housing. An actuating spring is provided for spring loading the brake lever, thereby maintaining a constant pressure by the brake surface on the rope. The actuating spring is provided with a quick release fastener to disconnect from the brake lever for converting the safety clamp appliance from a spring loaded mode to a non-spring loaded mode.

Abstract: A cable support assembly including first and second generally mating body members formed of a rigid, dielectric material. A bore defined between the mating body members to receive a cushion member is formed of a dielectric material substantially less rigid than the body member material. Outwardly extending flanges on the cushion member prevent axial movement relative to the body. Similarly, a cooperating tab and notch prevent axial movement between the mating body members. An enlarged boss is formed entirely within the first body member to facilitate a method of stringing cable. The first body member is secured to an associated support structure and the second body member positioned in close proximity. A cable is strung between the body members, the cushion member than received around the cable, and the first and second body members brought into mating engagement.

Abstract: A splicing tool system for high voltage transmission lines in which a pair of semi-circular jaw members with an internal configuration to match the lay of the wires of the transmission line is frictionally applied to the end of a cut transmission line and moved longitudinally of the line to replace any misplaced wires to a proper lay configuration on the transmission line. The tool is adapted to be operated by a longitudinal motion of remote control source and rotate about the axis of a transmission line.

Abstract: A strain relief device for resisting strain forces acting in a direction of pull-out of a cable relative to a cable closure, comprises a cable gripping member having at least two complementary jaw-like segments alignable for defining therebetween a tubular through opening sized for gripping a cable of a given diameter therewithin and an outer surface of predetermined configuration. These jaw-like segments have interengageable edge surfaces for defining a maximum inwardly compressed condition of the through opening corresponding to a predetermined limited maximum compression of the given diameter of cable for substantially preventing damage thereto. A generally annular locking member comprises a pair of locking segments defining an inner surface formed for complementary surrounding engagement with the gripping member outer surface and coupling structure for releasably coupling the locking segments together about the gripping member to retain the same in gripping engagement with the cable.

Abstract: An anti-telescoping cable clamp assembly for mounting and securing wire bundles. A strip of resilient material is coiled about a wire bundle inside a cable clamp assembly associated with an electrical connector. The strip of resilient material has first and second sides which include longitudinal side walls which define a channel therebetween, the channel providing a track for the tape to follow during build-up of the winding around the wire bundle and further preventing telescoping subsequent to assembly of the cable clamp about coiled strip of resilient material surrounding the wire bundle.

Abstract: An insulated distribution conductor separated from the substation by one or more fuses is protected from arc damage by a clamp device having sufficient mass to absorb the arc energy and thereby prevent burndown and diameter reduction of the conductor at a point where the insulation covering has been removed. The clamp comprises two members which are bolted together to surround the bare section of the conductor and provide additional heat-absorbing mass at the point where the arc tends to dwell, i.e. at the end face of the insulation covering farthest from the power source.

Abstract: A covered distribution wire is provided with a clamp device having sufficient mass to provide conductor protection against damage from fault current arcs over a section of the conductor where the insulation cover is removed for interconnection or insulator support purposes. The clamp comprises two members which are bolted together to surround the conductor section such that an enlarged disc-like end clamp portion is positioned about the conductor within one and a half centimeters of an end face of the adjacent wire cover. The two members are secured together such that a pair of slots exists between them along opposite sides of the conductor section with splatter barriers located on one end thereof. The slots are tapered with increasing width in the radially outward direction with the minimum width being great enough to avoid weldment and the maximum width being less than that which allows fault arc travel through the slot to the conductor section.

Abstract: A method of providing a strong field splice for a wire rope sling, and the like, involving the steps of taking the preformed wire rope and unravelling a selected length of the end of the rope, forming two groups of strands, and reweaving them together in the form of the loop; and when the reweaving is completed, the two remaining ends are woven together to again form the original wire rope. This dead end is clamped to the live portion of the wire rope by means of a streamlined clamp.

Abstract: A dead end connector for a transmission cable. The connector includes an elongated body and a cable-receiving longitudinal channel formed in the body. A pressure pad is provided with an elongated base portion which is adapted to be aligned with the longitudinal channel of the body. A cross piece is on the side of the base portion opposite to the side adjacent the channel of the body when aligned therewith and the cross piece extends across and outwardly from both sides of the aligned body and pad at an oblique angle with respect thereto. Coupling structure is provided for retaining the pressure pad in overlying aligned position with respect to the channel to hold a portion of a transmission cable therein with the cross piece enabling the provision of a holding pressure along at least a substantial portion of the engagement surface of the pressure pad with the transmission cable.

Abstract: An insulating protective cover sleeve assembly for a guy wire consisting of a longitudinally slit sleeve of insulating material having an enlarged bottom end portion. In the lower end portion of the sleeve is secured a clamp, likewise of insulating material. The clamp consists of two opposing jaws integrally connected by a flexible band. The jaws are formed with two sets of different-sized opposing arcuate recesses to receive different sizes of guy wires therebetween. One of the jaws has a counterbore hole to receive a clamping screw which is threadedly engageable in the other jaw to tighten the clamp. The wall of the enlarged sleeve portion has a hole registering with the counterbored hole so that a screwdriver or Allen wrench may be drivingly engaged with the clamping screw. A channel-shaped clip engages over the top corner portions of the sleeve segments adjacent the top of the sleeve slit and is secured to one segment.
