1. A rope-clamp comprising a base-plate, a flange or gripping-surface at one side thereof, a clamping-lever pivoted intermediate of its ends to the base-plate and having one end adapted to cooperate with the flange to clamp the rope, and a separate releasing-lever pivoted in operative relation to the clampinglever and adapted to engage the end of the same opposite the clamping end thereof, whereby the said lever may be released, substantially as shown and described.

2. A rope-clamp comprising a base-plate, an overhanging flange at one side thereof, a clamping-lever pivoted intermediate its ends to the flange, said lever being arranged with its long arm extending beyond the flange and having its clamping edge provided with a groove receiving the rope, and a releasing cam-lever pivoted to the base-plate and adapted to bear against the outer edge of the long arm of the clamping-lever, substantially as shown and described.

3. In a rope-clamp, the combination with a base-plate and an overhanging flange, of a clamping-lever pivoted intermediate its ends between the base-plate and the flange, having its long arm extended beyond the flange and adapted to clamp the rope between the inner wall of the flange and the short arm of the clamping-lever, a releasing cam-lever pivoted to the base-plate alongside of and adapted to bear against the outer edge of the long arm of the clamping-lever, near the free end thereof, and a guide for the rope arranged to bring the tension diagonally across the free end of the long arm of the clamping-lever, substantially as shown and described.

4:. A rope-clam p, comprising a base, a flange or support, a clamping-lever pivoted intermediate its ends to the flange, said lever arranged with the long arm extending beyond theflange, and a releasing cam-lever pivoted to the base-plate and adapted to bear against the outer edge of the long arm of the clampinglever,- substantially as shown and described.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

JOHN G. \VARDELL.
