At least one of the clamps has a first jaw in the form of a V-shaped recess, and a second jaw to force a line conductor into the recess in wedging contact with the converging surfaces of the recess. The converging surfaces of the recess are serrated to have a wiping action on the line conductor at the contact points so that when the line conductor is forced into the recess surface oxide on the line conductor at the contact points will be removed.Type: GrantFiled: September 25, 1989Date of Patent: June 19, 1990Assignee: The Detroit Edison CompanyInventors: Mitchell D. Charneski, Ralph G. Bonser

Patent number: 4925395Abstract: A clamping device having a U-shape provides a mechanical and electrical connection between two flat ribbons or strips of electrically conductive material. The strips of material may, for example, be thin copper bars for grounding purposes in an underground telephone vault. A mounting means allows the clamp to be secured to a structure wall. A pair of threaded bolts are offset from each other and are mounted in opposite legs of the U-shaped clamp. The bolts are formed with slotted heads for securing another conductor, such as a ground wire or ground ribbon, therein.Type: GrantFiled: December 29, 1988Date of Patent: May 15, 1990Inventor: George J. Franks, Jr.

Patent number: 4911572Abstract: A tie back clamp is provided for retaining a severed end of a power cable in a safe, removed position when it is necessary to cut the cable to perform service or otherwise work on the power line. The clamp retains a tail or end portion adjacent the location of the cut at a position transverse the remaining cable from which the stub or end portion extends.Type: GrantFiled: June 13, 1988Date of Patent: March 27, 1990Assignee: Houston Industries IncorporatedInventor: Danny R. Williams

Patent number: 4904193Abstract: A removable electrical ground clamp is provided that is easily installed on an outside electrical meter or breaker box by establishing pressure contact with the box. An attachment lug is provided on the grounding clamp for connecting a ground wire for use when electrical power is to be brought to a residence or some other outside electrical work or installation. The grounding clamp is designed to eliminate the need for access into an area of a residence or other building to establish a ground connection, provides instant visual inspection; and two grasping arms can be moved along an elongated member, which can be cylindrical, hexagonal, or U-shaped, in order to securely grip the outer surface of the meter or breaker box.Type: GrantFiled: April 20, 1988Date of Patent: February 27, 1990Assignee: Southwestern Bell Telephone CompanyInventor: Thomas F. Graves

Patent number: 4884976Abstract: A clamping device having a U-shape provides a mechanical and electrical connection between two flat ribbons or strips of electrically conductive material. The strips of material may, for example, be thin copper bars for grounding purposes in an underground telephone vault. One inner surface of the U-shaped clamp includes at least one projecting point which is positioned directly opposed to at least one threaded bolt movably disposed and extending from the opposed inner surface. The free end of the bolt is formed with a complementary recess and an abrading surface surrounding the recess. In a preferred embodiment, a pair of such threaded bolts are offset from each other and are mounted in opposite legs of the U-shaped clamp. The bolts may be formed with a slotted head for securing another conductor or bonding ribbon therein.Type: GrantFiled: August 22, 1988Date of Patent: December 5, 1989Inventor: George J. Franks, Jr.

Patent number: 4857020Abstract: A tap connector for establishing and maintaining an electrical connection between electrical conductors. The connector has a body whereof the sides define a channel which slidably receives a laterally expandible and contractable wedge assembly. In use, the conductors are rigidly held between the body and the expanded wedge assembly. To produce the required expansion, the wedge assembly comprises at least one driven block and at least one driving block which mate along respective opposed ramp surfaces inclined to the longitudinal axis of the channel. Relative longitudinal movement of the blocks causes the wedge assembly to expand and contract as required.Type: GrantFiled: February 8, 1988Date of Patent: August 15, 1989Assignee: Tridem Manufactured Products Inc.Inventor: Nobel W. Crosby

Patent number: 4846725Abstract: A clamp is provided for grounding electrical power lines and the like. The clamp automatically latches itself into a firm gripping relationship with the electrical power line when brought into contact with the power line.Type: GrantFiled: April 15, 1988Date of Patent: July 11, 1989Assignee: Houston Industries IncorporatedInventors: Danny R. Williams, Ronald J. Finke

Patent number: 4828504Abstract: A clamping device having a U-shaped portion between which material is positioned to be mechanically and electrically coupled to the clamp when engaged. One inner surface of the U-shaped clamp includes a conically-shaped tip of a hardened material which is positioned directly opposed to a threaded bolt or stud extending outwardly from the opposed inner surface of the U-shaped clamp for engagement with the conically-shaped tip. The terminal end of the oppositely positioned threaded bolt is formed with a complementary recess and, preferably, a knurled or serrated outer edge for abrading material which is engaged upon the tightening of the bolt. In one embodiment of the clamp, the threaded bolt includes a terminal portion adapted to accommodate and have secured therein a terminated ground wire, and the U-shaped clamp has an undercut portion for positioning against an upturned flange edge of a panel.Type: GrantFiled: November 5, 1987Date of Patent: May 9, 1989Inventor: George J. Franks, Jr.

Patent number: 4778413Abstract: The invention relates to a ground clamp for a welding apparatus. The ground clamp comprises a fastening screw rotatable in a body and a counter jaw formed in the body, which fastening screw and jaw together form a screw clamp by means of which the ground is fastened to a workpiece. The ground clamp further comprises a connection for fastening a ground cable to the body. Known ground clamps have structural disadvantages on account of which they are not reliable in operation and do not conduct sufficiently current in proportion to their size. The disadvantages are due to the fact that the contact between the workpiece and the ground cable is not sufficiently good to guarantee an even flow of the electric current. For the elimination of these disadvantages the connection of the ground cable comprises a cavity formed in the counter jaw perpendicular to the direction of the movement of the fastening screw, and fastening means which lock both a naked part of the ground cable and a cable insulation in the cavity.Type: GrantFiled: April 28, 1987Date of Patent: October 18, 1988Inventor: Reino Saarinen
