JOHN CLARK, OF BROOKLYN, NEW YORK, ASSIGNOR TO ELIZABETH CLARK, ELIZABETH GILMARTIN, MARY F. DEMAREST, AND IDA SMITH, ALL OF SAME PLACE.
i WRENCH.
SPECIFICATION forming part of Letters Patent No. 424,858, dated April 1, 1890.
Application filed June 15, 1889. Serial No. 314,373. (No model.)
To all whom it may concern:
Be it known that 1, JOHN CLARK, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York,
have invented new and useful Improvements in IVrenches, of which the following is a specification.
This invention relates to an improvement in wrenches; and it consists in the details of construction set forth in the following specification and claim and illustrated in the accompanying drawings, in which- Figure l is a side elevation, partly in section, of a wrench. Fig. 2 is a rear view of Fig. 1.
Similar letters indicate corresponding parts.
In the drawings, the letter A indicates a handle for the wrench. The movable jaw B is jointed to the handle by a joint or pivot O.
The jaw B carries a stud D, which supports a spring E. The pivot O serves as a fulcrum for a lever F G, the arm F of said lever striking against the stud D. \Vhen the arm G- is swung in the direction of arrow 1, the jaw B is swung in the'direetion of arrow 2, so that an object II-such as a pipe or tube-can be placed between the jaws B I. On releasing the lever F G, the spring E restores the jaw B to its original position, so that the object II is grasped between the jaws B I. The jaw I can be made adjustable by being supported in a suitable way or case K. and by providing an adjusting-screw L. The jaw I can thus be fixed nearer to or farther from the movable jaw 13, so that smaller or larger objects can be grasped by the jaws. By having the lever F G fulcrumed on the joint of jaw B a separate fulcrum or pivot for said lever need not he provided, thus simplifying and cheapening the construction. The spring E, being sup- 4o ported or pivoted on the stud D and pressing with its end portions against the jaw l) and handle A, tends to restore the jaw B to its original position when said jaw is moved.
What I claim as new, and desire to secure by Letters Patent, is-*' A wrench consisting of the handle A, carrying a jaw I, a swinging jaw 13, pivoted to the handle by a pivot-pin G and provided above said pin with a lateral stud D, a leaf- 59 spring E, supported by the said stud and bearing at its lower end against the wrench-handle and at its upper end against the swinging jaw, and the lever F, journaled on the pivot-pin of the swinging jaw and above such pin bearing against the lateral stud, substantially as described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
JOHN CLARK. Vitnesses:
WILLIAM C. IIAUFE, ERNST F. KAsTENuUBER.
