WILLIAM GENT, OF ROCKFORD, ILLINOIS. Y

CARRIAGE-WRENCH.

SPECIFICATION forming part of Letters Patent No. 360,874, dated April 12, 1887.

Application filed June 2S, 1886. Serial No. 206.546.

To all whom it may concern:

Be it known that I, WILLIAM GENT, a citizen of the United States, residing at Rockford, in the county of W'innebago and State of Illinois, have invented certain new and useful Improvements in Adjustable Carriage- Wrenches, of which the following is aspeoification.

My invention relates to improvements in that class of wrenches commonly known as the carriage-wrench. 7

My invention consists Iin producing a wrench having a pair of jaws hinged together by means of a hinge-joint, said jaws being capable of adjustment by means of a threaded handle passed through them, and also provided with a revolving `handle at the hinge-joint end thereof.

Referring to the accompanying drawings, which form apart of this specification, Figure l represents a side view of my improved wrench, with a portion thereof removed to show interior construction. Fig. 2 represents an isometrical View of a portion of the same.

Similar letters of reference indicate corresponding parts throughout the two views.

j A A represent jaws joined together by means of a hinge-joint, A2, and provided at their free ends with semi-rectangular mortises A3, for admitting and grasping the rectangular boss of an axle-nut.

B represents webs for strengthening the wrench-jaws A A.

B represents spurs for retaining the helical actuating-spring B2 in position.

C C represent tubular openings through the jaws A A', the latter being provided with an internal screw.

(No model.)

D represents a handle,- having -a tubular opening through the longitudinal center there- 4o of.

D represents a rotating axle passed through the longitudinal center of the handle D.

E represents a regulating-screw, for regulating the jaws A A.

E represents a handle, of good lengthand considerable weight, for operating the regulating-screw E, and also for revolving the Wrench.

This wrench can be manufactured most ad- 5o vantageously and cheaply of malleable or cast iron. I prefer to use round bar-iron for making the parts D E.

`To use the wrench most effectually, pass the Open jaws thereof over the boss of the nut to be removed. Tighten the screw E until the boss is held with a firm grip. Grasp the handleD with one hand, and with the other press the handle E backward until the nut starts from its axle. Then give the handle a vigorous toss, retaining the hold upon the handle D, and it will continue to revolve in a plane parallel to the carriagewheel until the axlenut is removed. A reverse mot-ion of the handle E will Obviously return the axle-nut to its former position.

I claim- The combination, with the jaw A, of the threaded jaw A', the tubular handle D, rotating axle D', screw E, and handle E', substan- 73 tially as described, and for the purpose specified.

TILLIAM GENT.
