Wire gripping apparatus

Claim 2

A wire gripping apparatus comprising a handle portion, a face at one end of the handle portion, a clamp section having a cable gripping surface confronting said face, and mechanism that moves the clamping section toward and from said face when the handle is rotated in different directions with respect to the clamp section, characterized by the face at one end of the handle being a plate, a bearing on which the plate and other portions of the handle are rotatable with respect to one another whereby the other portions of the handle can be rotated while the plate remains stationery and in contact with the cable that is being gripped, and further characterized by the face plate being generally annular with an inner cylindrical face that provides a bearing that contacts with a circumferential surface of the handle, the handle including a bushing that extends from one end of the handle, the handle having said circumferential surface on the bushing, and having thrust bearing surfaces on both sides of the face plate, one thrust bearing surface being a flange of the bushing and the other a shoulder on the handle.

Claim 3

The wire gripping apparatus described in claim 1 characterized by the bushing being secured to the other parts of the handle and rotatable as a unit therewith, the bushing having a longitudinal opening with screw threads therein that constitute a part of said mechanism, and a screw secured to the clamp section and integral therewith, said screw threading into the bushing and constituting another part of the mechanism from moving the clamp section toward and from the side of the face plate that confronts the clamp section, the face plate being of larger area than the clamp section and extending radially beyond the clamp section in all directions normal to the axis of the screw.

Claim 4

A wire gripping apparatus comprising a handle portion, a face at one end of the handle portion, a clamp section having a cable gripping surface confronting said face, and mechanism that moves the clamping section toward and from said face when the handle is rotated in different directions with respect to the clamp section, and said mechanism being a screw, connected to the clamp section as a unit therewith, the handle having a threaded end through which the screw threads during relative rotation of the handle with respect to the clamp section and screw, characterized by the screw being a carriage bolt having a head and having a polygonal shank section immediately below the head and before the threaded portion of the screw, the clamp section having an opening through which the polygonal section extends and the opening being shaped to prevent rotation of the screw in the clamping section, and a compression spring surrounding the screw and compressed between the clamp section and the handle for holding the clamp section against the head of the screw, the clamp section having a stop that contacts with the face at the end of the handle if the clamp section moves into a canted position on the screw beyond a limited angle that depends upon the extent of opening of the apparatus, and further characterized by the clamp section being a plate with a wide portion at one side of the screw and having a straight line depression in the face of the clamp section on the side thereof tHat confronts the face of the handle, said groove being in position to receive a length of wire or cable that is to be clamped and to clamp said wire or cable against the face of the handle, the handle being a metal tube of polygonal cross section with a threaded bushing in one end thereof for receiving the screw, the bushing being rigidly secured to the handle and having a portion of the bushing telescoped into the handle, and a plug closing the end of the handle remote from the clamp section and comprising a sleeve portion that fits into the tube and a decorated end wall that closes the tube and that extends beyond the outside circumference of the sleeve.

Claim 5

A wire gripping apparatus comprising a handle portion, a face at one end of the handle portion, a clamp section having a cable gripping surface confronting said face, and mechanism that moves the clamping section toward and from said face when the handle is rotated in different directions with respect to the clamp section, and said mechanism being a screw, connected to the clamp section as a unit therewith, the handle having a threaded end through which the screw threads during relative rotation of the handle with respect to the clamp section and screw, characterized by the screw being a carriage bolt having a head and having a polygonal shank section immediately below the head and before the threaded portion of the screw, the clamp section having an opening through which the polygonal section extends and the opening being shaped to prevent rotation of the screw in the clamping section, and a compression spring surrounding the screw and compressed between the clamp section and the handle for holding the clamp section against the head of the screw, the clamp section having a stop that contacts with the face at the end of the handle if the clamp section moves into a canted position on the screw beyond a limited angle that depends upon the extent of opening of the apparatus, and further characterized by the clamp section being a plate with a wide portion at one side of the screw and having a straight line depression in the face of the clamp section on the side thereof tHat confronts the face of the handle, said groove being in position to receive a length of wire or cable that is to be clamped and to clamp said wire or cable against the face of the handle, the handle being a metal tube of polygonal cross section with a threaded bushing in one end thereof for receiving the screw, the bushing being rigidly secured to the handle and having a portion of the bushing telescoped into the handle, and a plug closing the end of the handle remote from the clamp section and comprising a sleeve portion that fits into the tube and a decorated end wall that closes the tube and that extends beyond the outside circumference of the sleeve.
