IMPROVEMENT IN CARRIAGE-JACKS.

Specification forming part of Letters Patent No. 47,408, dated April Q5, 1865.

To all whom it may concern:

Beit known that I, AUSTIN W. FIELD, of Vergennes, in the county of Addison and State of Vermont, have invented a new and Improved Carriage-Jack, and l do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use. the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure l is an edge view of my invention; Fig. 2, a side view of the same.

Similar letters of reference indicate corre.- sponding parts.

This invention consists iu the employment or use ot' `two parallel slides titted in a suitable stock or standard and having a lever placed between their upper ends, all being arranged in such a manner that the device may be readily applied to axles of any height and the latter elevated and secured in such position with the greatest facility, to enable the wheels to clear the ground or tloor, so that they may be removed from and replaced on the axle for lubricat ing purposes.

A represents a stock or standard, which may be construeted of a solid piece of wood ot any proper dimensions, and having a groove, a, made in two opposite sides of it to receive metal sliding bars B B, which are allowed to work freely in the grooves and are connected or held in position near their lower ends by a screw, C, which passes through a vertical slo, b, made in the stock or standard and extending nearly the whole length of the same, (sce Fig. 2,) in which a greater portionot' the slot is shown by dotted lines.

D represents a lever,l which is fitted on a fulcrum-rod, c, passing through the upper parts ofthe sliding bars B B. The portion of this lever which encompasses ox isimmediately around the fulcrum-rod c is made wider or larger than the other portion, being nearly of circular form, as shown at d in Fig. 2, and this portion d is curved down from the other portion and is provided with a notch, e, to form a lip or bearing-surface for the axle to bear or rest upon.

The sliding bars B B are perforated with holes f, at a suitable distance apart, and a hole of the same size is Inade through the stock or standard to admit of a pin, E, passing through the holes in B and through the stock or standard. `By this means the bars B B may be raised and supported at different heights.

The stock or standard A is provided with a metal base or foot, F, secured to it by screws or bolts.

The implement is used as follows: The i'oot or base F should be placed as near under the axle tobe raised as may be convenient, and4 the sliding bars B B are raised so that their tops will be a short distance above the under side or bottoni ofthe axle, the bars being then secured in position by thepin E. The lip of the notch is then adjusted under the axle and the outer part ot' said lever depressed, which causes the axle to be raised, the latter resting on the ilat or plane portion a* ot' the lever directly over its fulcrumrod c, while the larger arm of the same bears against the stock or standard, as shown clearlyin Fig. 2.

The superiority of this invention consists in the great purchase the lever has, its lightness and compactness, together with its simplicity, the speed and facility with which it may be operated, the convenience with which it may be carried by peddlers and others who are constantly on the road with Wagons, its durability, and the low price at which it may be afforded.

I claim as new and desire to secure by Letters Patent- The stock or standard A, perforated sliding bars B B, and lever D, in connection with the pin E, all arranged `substantially as shown and described, to form a new and improved carri-a ge-j ack.

AUSTIN W. FIELD.
