US Patent:

50059408, Apr 9, 1991

Filed:

Jun 5, 1990

Appl. No.:

7/535372

Inventors:

Henry J. Modrey - Palm Beach FL

International Classification:

G02B 638

US Classification:

350 9621

Abstract:

A spirally wound resilient cylindrical or tubular connecting element adapted to connect or terminate pressure sensitive or brittle elongated conducting elements in either supporting or end-to-end conductive relationship. In one embodiment, the connecting element is comprised of a generally resilient cylindrical member having a hollow internal passageway therethrough adapted to receive said conducting elements in end-to-end relationship, said cylindrical member having integrally associated therewith a second, smaller, cylindrical member defining a second hollow passageway therethrough, said second hollow passageway adapted to receive an expansion strand or rip wire, said expansion strand having an outside diameter slightly larger than the internal diameter of said second hollow cylindrical passageway, wherein when said expansion strand is disposed within said second hollow cylindrical passageway the internal diameter of said first hollow cylindrical passageway is expanded beyond its equilibrium diameter. When said expansion strand is removed from said second hollow cylindrical passageway, the inherent resiliency of said connecting element urges said connecting element to grip the conducting strand or strands about their outer periphery with a generally equally directed radial force, thereby holding said conductive strands in firm coaxial alignment without disturbing the conductive material of the strand or strands.

International Classification:

F16B 1306

US Classification:

85 74

Abstract:

A device for locking an insert in a support having a receiving hole or sealing a tubular member such as a pipe, consists of a somewhat bottle-shaped bushing having a cylindrical collar or bushing portion, and a conical portion secured at its narrow end to said collar, an inside screw thread, and a locking ring seated on the cone adjacent to the collar. The dimensions of the collar section of the bushing, the cone and the locking ring are so correlated that bushing and locking ring fit the cross-section of the hole with slight friction when the insert is placed in the hole. Locking of the insert in the hole is effected by inserting a screw bolt or screw tightening means into the insert coaxial therewith. This causes lifting of the insert which in turn effects spreading of the locking ring thereby pressing the same against the wall of the hole. The depth to which the insert is inserted into its hole provides means for accurately regulating the degree of force applied by the expanding insert on the surrounding hole wall.
