CLAMP.
SPECIFICATION forming part of Letters Patent No. 521,872, dated J' une 26, 1894.
' Application led October 30, 1893. Serial No. 489,462. (No model.)
To all whom it may concern.-
Be it known that we, WILLIAM YEAGER and BROR E. WESTLIN, of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Clamps, of which the following is a specification. y
Figure l is a plan view of the clamp. Fig. 2 is a side view and Fig. 3 an end view.
a a are side plates. b is a stud secured between them at one end. c is a sheave revolubly mounted between them toward the other end. d d are the jaws of a clamp mounted upon one of the platesa at the said other end; one of said jaws being arranged toslide up and down in the guideways e e and being operated by the thumb-screw j threaded to the cross member k at the top of said guideways. The cross member lo, the guideways c e and the lower jaw d constitute substantially a loop with one side of which the plate a joins. One end, as Z, of a rope is placed around the stud b and secured there; another end, as Z', is passed between the jaws d and d', thence around'the sheave c and thence backagain on top of itself between the jaws. The thumb-screwj is then screwed down so as to clamp the end Z. Now, by unscrewing so as to raise the jaw d, the end Z will be unclamped sufficiently so that by pulling on its loose end, it can be pulled around the sheave c till taut. Thereupon, by screwing down the thumb screw j it will be grasped iirmly by the jaws and heldthere. This contrivance, comprising `the sheave c and the clamp, may be employed for only one end of the rope; and We therefore do not wish to be limited to the stud b as the means to retain the clamp in the position desired.
Theprincipal use of the sheave c is to aid Vthe clamp in holding the rope securely and to allow the rope to pass freely over it in increasing and decreasing the slack so as to facilitate placingthe rope in a positionv to be secured by the clamp. Where a rope is under strain, as of a suspended weight, its length may be taken up or increased without removing the strain. `This feature makes it ex? `and a suitable frame, substantially as described.
