Abstract: As a preferred alternative to whipping a boat-line with tape or a wax material to limit wearing and unraveling over time, the apparatus of the invention affords a secure, more attractive appearance through the use of a pair of cylinders, one of which receives the boat-line, and the other of which threads over it, with the effective screwing of the two together additionally producing a force upon a series of compressible fingers that extend inwardly from the outside surface of the first cylinder in clamping onto and holding the boat-line in position. The two cylinders may be capped in providing a finished-off appearance to the construction when the line is thus secured.

Abstract: This invention provides an improved cable clamp construction for telecommunication cables such as coaxial cables made from continuous filaments of optical glass fibers which are surrounded by an annulus of aramid material and contained within an outer plastic jacket. In order to provide intermediate gripping action on the continuous cable without its interruption, the gripping action must be carefully controlled and distributed over a relatively sizable intermediate area of the cable to prevent damage to the fragile fibers of the cable over a long useful life in varying climatic conditions. The gripping clamp is comprised of a limited number of components which are capable of surrounding and gripping the cable without undue flexure, the clamp being comprised essentially of a separable sleeve member and a separable plug member, both of which have tapered surfaces to positively secure the cable with compressive forces over a localized area.

Abstract: A swivel end fitting for rope, cord or leash designed to allow said rope to be attached to another object and thereafter withstand considerable shock without coming apart or becoming disengaged from said rope. The invention is made up of a pointed screw-shaped base element permanently attached to the rope; a central socket element for receiving the screw-shaped base element at one end, and receiving a rounded terminal element at the other end; and a swivel eye terminal element having a stem and head thereon, said stem and head being bisected by a linear gap. As the terminal element is pressed into the socket element, the head is squeezed together over the gap until it crosses a collar on the socket element at which point the head pops back into its original position, now able to freely pivot. Then the screw-shaped base element is fully inserted into the opposite end of the socket such that the point thereof protrudes into said gap, preventing the head from squeezing back out of the collar.

Abstract: A self locking cable end termination socket assembly has a one-piece tapered wedge as a locking device for a cable that fits into a housing with two parts that are locked together. The wedge and a cable looped over the wedge fit within an interior opening in the housing. When the cable is tightened, the wedge tightens against surfaces defining the opening in the housing and wedges in place. The two housing parts include a saddle and a cap which fit together and are held in a fixed position with interlocking members. The cap has a knock-off lug that, when hit with sufficient force, such as by using a weight on an end of a cable to form a pendulum ram, will release from the saddle, making removal of the wedge and the cable greatly simplified.

Abstract: A clamp is provided at the nut of a guitar for clamping the strings to prevent them from sliding across the nut. The clamp was a boss portion in which a bore is formed. A set screw is provided in one end as a plug. A screw with a handle is threaded into the other end of the bore and six cylindrical spacers are disposed between the plug and the screw with the handle. Slots are cut in the boss which expose the ends of the spacers so that the strings of the guitar can be slid between the ends of the spacers. Tightening the screw with the handle clamps the strings between the spacers. The clamp has a step, formed on one side of it, on which a nut is mounted. The nut is divided into three sections whose heights and orientations are adjustable to suit the camber of the fret board of the guitar and the height of the frets, so as to eliminate the need for shimming or filing the nut.

Abstract: An improved cord grip and strain relief fitting to restrain and seal flexible cord to an enclosure or junction box. The structure includes a body member, a grommet, a strain relief member and a nut. Tightening the nut onto the body member results in radial forces between the grommet and the cord to restrain the cord and provide a water tight seal. The grommet is stuffed into the body member by an interaction between the grommet and the strain relief member as the nut is engaged with the body member. The lower end of the strain relief member has legs which mate with sockets in the grommet and which receive a radial inward force during final assembly causing the legs to pivot inward and apply an additional retaining and restraining force on the cord. The strain relief member has an upper portion which flares away from the cord thereby providing an increased radius of curvature if the cord is deflected from its longitudinal direction at the external end of the fitting.

The device comprises a cylindrical body portion and a pair of semicircular plug halves which are retained proximal to the body portion and which cooperate to securely grip the tape in a gradual arcuate path without the use of excessive clamping pressures that would normally cause substantial reductions in the tape's tensile strength. The plug halves have opposed generally flat mating surfaces and oppositely disposed convex arcuate surfaces. The halves are retained proximal to the body portion with the mating surfaces thereof in generally aligned relation by means of spaced bolts which extend generally perpendicularly through the mating surfaces into the body portion.

Abstract: A breaking and insulating clamp for tensioned electrical conductors is disclosed, and which comprises an elongate bar of an electrical insulating material, with the bar mounting separate clamping members at longitudinally spaced apart locations for separately securing an electrical conductor or the like at each location. This permits the conductor to be severed between the clamping members, so that the remaining portions of the severed conductor are isolated and insulated from each other. In the illustrated specific embodiment, the clamping members each include a U-shaped bolt received within mating channels in the bar so as to preclude relative longitudinal movement between the bar and the bolt, and a pair of cooperating plates mounted on the bolt. The plates are designed to be clampingly pressed together so as to securely retain an electrical conductor extending therebetween in the longitudinal direction.

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 bus conductor with a cylindrical external surface is supported on an insulator by first and second bus-supporting members, each comprising spaced legs and flanges at the free ends of the legs. The bus-supporting members embrace the bus conductor when the flanges are in juxtaposition. One set of flanges is fastened together by fastening means comprising a screw extending between the flanges and threaded into one of the flanges and a nut positioned between the flanges and threaded onto the screw. The nut is axially movable on the screw between first and second positions. When in the first position, the nut is tightened on the screw against the juxtaposed flange of one of the bus-supporting members, thereby locking the flanges in a fixed-joint position. When in the second position, the nut is tightened on the screw against the juxtaposed flange of the other bus-supporting member, thereby locking the flanges in a slip-joint position.
