TO ALL WHOM IT MAY CONGERN:

m Be it known that I, JOSEPH F. EMMERT, of Quincy, in the county oiFranklin,` and State of Pennsylvania, y have invented a. new and improved Carriage-Jack; and I do hereby declare that the following is a full, clear,

and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this speeiiication, in which- Fignre'l is 'a side view of my improved carriage-jack, pantroi' which is removedV to show the slide-lifting arrangement.

Figure 2 is a. view of the same on a di'erent side.

Similar letters of reference indicate likeV parts.

This invention relates to a new and improved carriage-jack, which is operated by alever to raise a sliding rack It is made wholly of cast iron, and is both cheap and convenient.

A is an upright 'stand supported on legs a a, uuited by a cross-brace, b. The stand A has grooves on opposite sides, formed by projecting edges or side strips e c, iig. 2, and fitted in a. groove'on one side isa. sliding lift-rack, B, 'operated by the lever Ctbat is connected to it by a link-rod, d, which is pivoted to a lug, e, that passes through a vertical slot, g, in the stand A. The leverC is pi'voted to .a lug, h, at the bottom of the stand A, and on the lower end of Athe sliding lift-rack B is a lug, z', which also Vpasses through the slot g, and is held in place by a pin through it running across the slot. The lift-rack Bvhas its teeth c k so arranged that a supporting slide piece, D, may catch in them and rest at any point for the purpose of adapting the jack to axles of different height.

For operating the jack, the slide piece D being placed at the proper lpoint of the rack B, when set under the axle, the end of the lever C may rest on the ground, as is shown in red, iig. 1, or be held at some convenient i position, when, as is obvious, by lifting the lever C, the sliding rack will also be lifted and raise the axle, and when the lever reaches an upright position it will remain in that position and keep the sliding rack B and the slide piece D in place for supporting the axle.

Having described my invention, I claim as new, and desire to secure by Letters Patentl The construction and arrangement of the slotted stand A, in which the toothed sliding lift-bar B, provided with the slide piece D, works, the lever Cpivoted vto the lug h at the bottom of the standard A, and tothe i lower end of the link d, whose upper end is pivoted to the lug e of the lift-bar B, working in the slot g of standi ard A, substantially as described for the purpose specified. i JOSEPH F. EMMERT.
