T0 a/ZZ whom t may concern:

Be it known that I, PERRY BROWN, a citizen of the United States, residing at Wilmington, in the county of New Castle and State of Delaware, have invented a certain new and useful Improvement in Lifting-Jacks, of which the following is a'specification, reference being had to the accompanying drawings.

Referring now to thezfdetails of the draw ings by numerals, 1 indicates the standard of a jack provided With-my iimprovements, 2 the plunger thereof, and an adjustable arm extending therefrom. To operate the plunger, I have pivoted to the standard near its base a lever 4, havinga removable handle 5, provided with a socket '6to' receive a tenon (shown in dotted lines in Fig. l) on the end of the lever. The handle is provided with a wrench, formed of a fixed jaw 7 and a movable jaw 8, which latter is capable of adjustment by means of a thumb-screw 9, so as to t it to hold any sized nut. To prevent the jaw moving when adjusted, Ilprovide a series of teeth '1o In the beek of 4`me movable jew and the face of the handle.. By this construction the nut may be unserewed from a carriage-axle,-and the handle, with the nut still in the jaws, as shown in dotted lines in Fig. 2, may be attached to the lever and then used to operate the same and so raise the plunger', when' the wheel may be' madetoslidesidewise onto the arm 3, asi'n'dicated 'dotted lines in Fig. l, so that there'gis non.ylne`cessity of touching the nut withthe hands,and lthus soiling the fingers is' prevented. 1

I am aware that it hasjbeen proposed to provide a lever for a jack witlran adjustablej awed Wrench on aremovable'handle in which it is necessary to remove'ithe n'ut from the jaws of the wrench before the twojparts of the handle can be operativelyunited'f'r use; but with my arrangement of a deepsocket in the handle adapted to receive the end of the operating-lever, even j whenthe nut is between the jaws, the nut can be allowed to remain in the jaws of the wrench, and thus the operator need not soil his lingers by handling the nut. Y y f What I claim as new is- ,Y

In a wagon-jack, a two-part leverj forbperating the same, one part being detachable and the other part pivoted to the 'I standard, the detachable part being provided'iwith a fixed jaw and a movable jaw formingawrench,

and one of the two parts havingV a'socket independent of the jaws of the wrench to receive the end of the` 'other part,x,whereby the nut of the Wagon-axle may be heldin the wrench while the twof parts are,i111( )per'ative connection, substantially y.as described. l

In testimony whereof Iiaflixinyffsignature, in the presence of twowitnesses, this 2d day of June, 1896.

BERRY BROWN.
