GEORGE W. DAVIS, OF BURNSIDE, PENNSYLVANIA.

WAGON-JACK.

SPECIFICATION forming part of Letters Patent No. 361.813, dated April 26, 1887.

Application filed October 6, 1886. Serial No. 215,468. (No model.)

To all whom, it may concern:

Be it known that I, GEORGE W. Davis, a citizen of the United States of America, residing at Burnside, in the county of Clearfield and State of Pennsylvania, have invented certain new and useful Improvements in Vagon or Buggy Jacks, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has for its object to provide an improved, novel, and simplified vehiclejack which will be durable in construction and efficient in its action, combined with ease of manipulation and ready adaptation to the purpose contemplated. l

To these ends my improvements consist, essentially, of a vertical support or standard having its upper portion centrally slotted for the reception therein of the one end of a lever, the axis of which is adapted to engage with one of a series of recesses in the side of said support, and said lever being provided upon its upper surface with a ratchet-plate which is adapted for operation in connection with a pivoted pawl in the manner and for the purposes as will be hereinafter fully described, and pointed out in the claim.

In the accompanying drawings,Figure 1 represents a side elevation of my completeinven-` tion, and Fig. 2 a detail sectional View thereof.

Similar letters of reference indicate like parts in both figures of the drawings.

In carrying out my invention I provide an upright standard, A, having a suitable supporting-base, A', and strengthening-brace A2, as shown, the upper portion of said standard being centrally slotted, as shown at B, for the reception therein of the one end of the lever C. Upon each side of the slotted portion Bis provided a series of recesses, a, the inner ends of which are provided with semicircular bearings a, for the reception of the ends of the axle b of the lever C.

Vertical and overhanging rods D are secured to the front upper part of thestandard A, one upon each side of the opening B, the object of which is to prevent the lever C from being disengaged from the standard, yet permitting of the same being readily raised or lowered in the series of recesses a. Upon the upper surface'of the lever C is providedaratchet-plate, E, with which engages the lower end of the pawl F, the upper end of which is pivoted at G in the upper end of the recess B, as shown.

In the operation of my improved device the lever O is adjusted in either of the series of recesses a, according to the height of the vehicle-axleto be raised. Now, by depressing, the handle of the said lever, the axle is ele- Vated to the desired point, the pawl F dropping into one of the series of teeth on the ratchet-plate E, according to the depression of the lever, and rmly holding the axle at the desired position for the ready removal or replacement of the wheel during the operation of lubricating the axle.

The construction ofA my improved vehiclejack is such that it can be readily adjusted to Vehicle-axles of different heights, is easily and quickly manipulated, and occupies but little space when not in use.

Having thus described my in vention, I claim as new and useful- In a wagon-jack, the standard A, having a base-block and a connecting metal brace, said standard being vertically slotted, the side walls
