  • Patent number: 5058838
    Abstract: A supporting assembly for energized tubing includes an elevated post joined to pairs of oppositely facing and laterally spaced apart upper and lower generally C-shaped clamp arms at its top end and to a base at its bottom end. A retainer member is connected to the base and includes a latch element engageable with catch elements on the base and which serve to both limit angular displacement of the base, post and clamp arms while temporarily alternately locking them in either an open or closed position. In the open position, a cable may be inserted between the spaced apart lower clamp arms and a larger diameter portion of tubing inserted between the spaced apart upper clamp arms. Thence, by angularly displacing the post and arms substantially 90 degrees, the pairs of clamp arms are moved into firm engagement with the tubing while captivating the cable therebeneath.

  • Patent number: 4997147
    Abstract: A supporting assembly for energized tubing includes an elevated body having a top post section to which is mounted a rotary head having a clamp member base defining a longitudinal axis. A pair of lock arms project upwardly and are axially spaced apart to form a clearance therebetween which extends transversely of the base longitudinal axis. Position control elements on the head and elevated body cooperate to restrict arcuate displacement of the head to and between locked and unlocked positions disposed substantially 90 degrees apart. In the unlocked position, a tubing length may be inserted in the transverse clearance between the lock arms, following which, turning the head approximately a quarter turn swings the lock arms into engagement with the tubing with the position control elements serving to maintain an arcuate biasing force upon the head and lock arms in order to accommodate tubing of various diameters in a positive gripping manner.

  • Patent number: 4944699
    Abstract: A splicing device to join the free ends of two cables. The present invention provides a non-conductive housing assembly around a possibility of three inner conductive connector means. The inner conductive connector means joins the free ends of a conductive cables such that there is an uninterrupted electrical flow path between the ends of the cables. The connector housing provides a protective outer housing around the assembly and holds the spliced ends of the cables together. The splicing device can be readily installed to provide a safe and reliable splicing of free cable ends.

  • Patent number: 4874909
    Abstract: A connector device for splicing two conductors includes a pair of joined body sections provided with axially offset cable conductor holes leading to an intermediate cavity. A grip element with the cavity, having one or more helical coils has its opposite ends anchored relative to the opposed end faces of the two body sections. Two cable conductors are electrically and mechanically joined by inserting the conductor ends through the body sections and into the cavity, within the confines of the grip element coils following which, twisting of the body sections relative one another constricts the grip element convolutions tightly about the contained conductor ends. The interlock may be further enhanced by the inclusion of a knobbed lock post disposed within the connector cavity and which assists in deforming the conductor ends as the coil grip element is constricted thereabout.

  • Patent number: 4842535
    Abstract: A connector for discharge electrodes of luminous gas tubes includes an insulative barrel receiving a power cable at one end for attachment to a fixed end of a resilient contact member. The opposite end of the barrel is open and threaded, to receive the crimped and headed tip of a gas tube having electrode conductors projecting therefrom. A lock element is applied to the crimped portion of the gas tube end and is axially captured thereon so that following insertion of the tube tip and lock element into the barrel open end, a cap surrounding the gas tube engages the threads of the barrel to radially and axially retain the tube tip within the barrel interior with its electrode conductors firmly biased against a displaceable end of the resilient contact member.
