TILL-IA M H. TRUS'IY, 0F PHILADELPHIA PENNSYLVANIA.

Y Letters Patent No. 70,291, dated Octobe?` V29, 1867..

@Ligt Stlnhnlrreferrrh tu iii this etter atent zmh netting mi nftlge tame TO ALL WHOMIT MAY CONCERN l Be it known that I, WILLIAM H. TRUSTY, of the city and county of Philadelphia., and State of Pennsylvenia, have invented a new and useful'Irnprovement in Yagon-Jacks and I do hereby declare that the following is a. fullLclear, and exact description thereof, which willgenable those skilled in the art 15o-raalte and use the same, reference being had to the accompanying drawings, und to the letters` of reference marked thereon.

The wagon-jack embraced in the present- .inventiol'nvas in the ordinary jacks, consists of a. foot or basepirce, provided with a standard, carrying the lifting-bar or lever, but in addition thereto has combined with it' 'a pawl-'and-ratchet surface, for holding-the lifting-bar inv whatever position it may be brought by the use .of the jack, for raising or lifting a wa'gon or carriage-axle.

In the accompanying plate of drawings my 'improved wagon-jack is illustratcd,.the figure being a. side elevation oft-the same.

A,-in the drawings, represents the base oi-.foot-p'ieceto the jack, and B its standard, ixedf in an upright position to such foot-piece, and in such position braced by sidebrnco-rods C, properly applied thereto. D, the

lifting-bar or'lever to the jack, arranged in the upper and slotted end E, where it is hung by across-pin, a, for

`turning on the notched sides I?, in any one of its series of notches G, according as the height of the wagonwaxle on which the jack is to be `used may require. This lifting-har D, atene end H, is adapted for being graspedL by the hands, and at the other, I, for being set under awagon-axle. K, :t pawl-rod, hung at one end Atoa staple,lS, upon the under side of the handle, 'to the lifting-bar D, and, by its other end, passing through l Vthe guide-loop L to the ratchet-teeth M of the standard B, with which, by such end, it is made to engage, as

shown. N, a thumb-lever, hung to a. vlifting-bar, D,a.nd by its-end O, through a link-piece, P, hung or connected with the pawl K.' l

By pressing on this thumb-lever thepawl K is released or lifted from the ratchet-tooth with which it may he engaged, thus leaving the lifting-bar free to 'be swung or turned for lifting the axle under which it may have been placed;` when, having thus raised it to thedesired height, if the pressure upon the thumb-lever be then removed, the pawl, of itself, engages with the ratchet-tooth corresponding in position to its lower end, and there .secures and holds the lifting-bar, as is obvious.

Having thus described my invention, I claim :is new, and desire tosecure by Letters Patentt The pawl-and-ratchet surface, in combination with the lifting-bar, when such pawl is provided with a liftinglever, substantially as and for the purpose described.

2. In combination with the above, AI claim the series of notches to the standard of the jack, as herein described, for the purpose specified. I
