Abstract
Abstract A substantially cylindrical plug-like clamp having a rectangular socket in one extremity, to receive the wires, and a circular socket in the other extremity, to receive a flexible tension element or fishing tape. A lever-actuated, flat shaft transversally crosses the rectangular socket which, when rotated, clamps insulated wires in the latter socket and a screw-actuated nipple in the circular socket acting to secure the extremity of a fishing tape in the latter socket.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
168 words
A clamp device for attaching a plurality of wires to a fishing tape for drawing the wires through a conduit comprising: a. an elongated substantially cylindrical coupling block having an outer diameter less than the inner diameter of said conduit; b. a wire-receiving cavity extending axially inward from the rear extremity of said block, said cavity having opposed internal surfaces, said cavity receiving said wires so that said wires extend in a generally axial, rearward direction from said block; c. means for clamping the ends of the wires radially outward against the opposed internal surfaces in said cavity; d. lever means for actuating said clamping means and being positioned within the lateral confines of said cylindrical block in clamping position; and e. means for detachably attaching a fishing tape to the forward extremity of said block, said attaching means being within the lateral confines of said coupling block and attaching said fishing tape so that said fishing tape will extend in a forward axial direction from said block.
Claim 2
Dependent Claim
168 words
A clamp device for attaching a plurality of wires to a fishing tape for drawing the wires through a conduit comprising: a. an elongated substantially cylindrical coupling block having an outer diameter less than the inner diameter of said conduit; b. a wire-receiving cavity extending axially inward from the rear extremity of said block, said cavity having opposed internal surfaces, said cavity receiving said wires so that said wires extend in a generally axial, rearward direction from said block; c. means for clamping the ends of the wires radially outward against the opposed internal surfaces in said cavity; d. lever means for actuating said clamping means and being positioned within the lateral confines of said cylindrical block in clamping position; and e. means for detachably attaching a fishing tape to the forward extremity of said block, said attaching means being within the lateral confines of said coupling block and attaching said fishing tape so that said fishing tape will extend in a forward axial direction from said block.
Claim 3
Dependent Claim
22 words
A clamp device as described in claim 1 in which the opposed internal surfaces are provided with: a. ratchet-like, forwardly directed teeth.
Claim 4
Dependent Claim
89 words
A clamp device as described in claim 1 in which the means for clamping the wires comprises: a. a rotatable flat-sided axle member extending transversally across said block and across said cavity between the side surfaces thereof and intermediate the upper and lower surfaces thereof; and b. said lever means being attached to said axle member externally of said block for rotating the latter from a horizontal open position to receive said wires to a vertical closed position to compress the wires against said upper and lower internal surfaces.
Claim 5
Dependent Claim
77 words
A clamp device as described in claim 3 in which the lever means comprises: a. a U-shaped, bifurcated lever member having two legs joined by a connecting bridge portion; b. means for fixedly attaching the extremities of the two legs to the extremities of said axle member exteriorly of said block so that when said lever member is swung toward and away from said block said axle member will respectively rotate to the closed and open positions.
Claim 6
Dependent Claim
41 words
A clamp device as described in claim 4 having: a. a conical forward extremity on said block, said bridge portion having a semi-conical contour to align and fit against the conical forward extremity of said block when in the closed position.
Claim 7
Dependent Claim
35 words
A Clamp device as described in claim 5 in which: a. a contoured indentation formed in the conical forward extremity of said block into which said bridge portion is interfitted when in the closed position.
Claim 8
Dependent Claim
64 words
A clamp device as described in claim 5 in which the means for detachably attaching a fishing tape comprises: a. a threaded tape cavity extending axially inward from the conical forward extremity of said block; b. a tubular nipple threaded into said tape cavity; and c. a head formed on said nipple positioned to contact and retain said bridge portion in the closed position.
Claim 9
Dependent Claim
30 words
A clamp device as described in claim 7 having: a. an axial opening in the head of said cap for receiving and attaching a fishing tape in said tape cavity.
Claim 10
Dependent Claim
23 words
A clamp device as described in claim 8 in which: a. said cap is externally knurled to facilitate thumb and finger engagement therewith.
Claim 11
Dependent Claim
64 words
A clamp device as described in claim 1 in which the means for detachably attaching a fishing tape comprises: a. a threaded tape cavity extending axially inward from the conical forward extremity of said block; b. a tubular nipple threaded into said tape cavity; and c. a head formed on said nipple positioned to contact and retain said bridge portion in the closed position.
