Patent number: 5061826Abstract: A narrow elongated housing is provided constructed of an inner ribbed conduit which is overlaid with two layers of high strength rods. Each layer is contra-helically wrapped with opposing end portions compression secured in a termination chamber. The chamber is formed between a sleeve, which is attached to opposing ends of the conduit, and an outer termination enclosure.

Patent number: 4596486Abstract: A termination for cables of the type having a central bundle of conductors surrounded by strength members includes a rigid sleeve closely surrounding the bundle of conductors beneath the strength members and a rigid housing surrounding the strength members outwardly of the sleeve. The strength members are encapsulated in a hardenable material to define an enlarged lug closely received between said sleeve and housing. The housing and lug have cooperating cam surfaces for compressing the lug between the housing and sleeve when a pulling force is applied to the housing. The outer diameter of the housing is cylindrical and has a diameter approximately the same as the diameter of the cable outer cover.Type: GrantFiled: October 17, 1983Date of Patent: June 24, 1986Assignee: PMI Industries, Inc.Inventor: Otto C. Niederer, Sr.

Patent number: 4507008Abstract: A cable termination arrangement includes a tapered socket body and a mating plug covered with a sleeve of malleable material. Cable strands are inserted and spread out inside of the socket. The plug and sleeve are pushed into the socket for forcing the strands into the sleeve. When a tensile force is applied to the cable, slippage between the cable and the socket is zero.Type: GrantFiled: May 13, 1983Date of Patent: March 26, 1985Assignee: AT&T Bell LaboratoriesInventors: Ali Adl, William D. Backus

Patent number: 4464812Abstract: A mechanically connected socket for `on-the-job` connection with structural strand includes a sleeve and an internal wedge shaped member through which the center core of the strand is received and retained while one or more outer layers extend longitudinally about the wedge and a bulbous head which, when assembled, encapsulates the strand.Type: GrantFiled: October 24, 1983Date of Patent: August 14, 1984Assignee: The Crosby Group, Inc.Inventors: Edward J. Crook, Jr., Gary R. Baxter

Patent number: 4432663Abstract: A cable pulling eye assembly comprises a spike (16) having an auger thread (18), a coaxially mounted shell (36) and an eye (31) with a threaded opening (34), which is mounted on a threaded rear section of the spike. The eye is rotated by a power tool to advance the auger into a bundle of wires (11) of a sheathed cable (10). The shell is subsequently crimped to further force the wires into the flute defined by the auger thread. A pulling steel cable is attached to the eye to draw the cable between telephone poles or through an underground conduit.Type: GrantFiled: November 3, 1980Date of Patent: February 21, 1984Assignee: Western Electric Company, Inc.Inventors: John L. Lasak, Costenzio A. Tuzzalino

Patent number: 4419534Abstract: In an end cap for communications cables, and particularly one equipped with a pulling eye, an axial spigot provided with cable engaging enlargements is also formed so as to define longitudinally extending surface channels for the passage of gas, which channels are protected from entry of cable conductors either by being oriented at an angle to the lay of the conductors, or by the insertion of a small bore air carrying tube.Type: GrantFiled: November 30, 1982Date of Patent: December 6, 1983Assignee: American Sawmill Machinery CompanyInventor: Liam D. Dwyer

Patent number: 4360288Abstract: A fiberglass sucker rod construction is disclosed comprising a cylindrical fiberglass rod having a steel connector member adhesively bonded to each end thereof. The steel connector members are basically identical in their manner of being affixed to each end of the fiberglass rod, each connector member having an internal receptacle defining a series of tapered annular spaces for receiving an epoxy adhesive material which bonds the fiberglass rod in the metal connector member, thereby forming a unitary sucker rod having a male thread connector at one end and a mating female connector at the other end thereof. The epoxy adhesive cures, forming a sleeve having a series of annular tapering surfaces defining annular wedges that are oriented such that tension applied to the rod causes the wedges to be compressed between the rod and connector member, resulting in a radially inwardly directed force to retain the rod in position against such tension.Type: GrantFiled: September 17, 1979Date of Patent: November 23, 1982Assignee: Fiberflex Products, Inc.Inventors: Woodrow T. Rutledge, Jr., Russell P. Rutledge, John E. Freeman, Steven D. Clark

Patent number: 4295250Abstract: A cable dead end, and method of dead end formation, that can be readily utilized in the field with a minimum of equipment and components, yet providing a durable, tight, dead end. The cable end is cut off and a ferrule is slipped over the cable end onto the cable. The strands at the end of the cable are unwound and separated, an insert is disposed over the core strand and is disposed within a general bird-cage configuration of the cable strands at the cable end. The ferrule is then moved over the bird-cage configuration and to the end of the cable, and the void space inside the ferrule between the strands, ferrule, and insert is packed with steel wool. Then an anerobic, structural, single component adhesive (e.g. an oxygenated methacrylic) is poured into the ferrule interior volume, and quickly cures. Preferably the insert is barbed, and the interior cross-section of the ferrule is elliptical.Type: GrantFiled: September 28, 1979Date of Patent: October 20, 1981Inventor: James A. Dupuy

Patent number: 4279531Abstract: The invention provides an insert for use in retaining an end portion of a cable in a socket. The insert has first and second ends and defines a central opening extending between the ends. A portion of the opening adjacent the first end of the insert has a diameter which forms a loose fit on the center wire of the cable, and the remainder of the opening is at least as large as this diameter so that during assembly a filler material can be entered into space around the center wire in the opening. The invention also provides an end assembly on a cable using the insert.Type: GrantFiled: December 18, 1979Date of Patent: July 21, 1981Assignee: Greening Donald Co. Ltd.Inventor: Kenneth G. McKenzie
