Abstract
27,668. Warren, W. T., Warren, E., and Mustard, D. Dec. 5. Lifting-jacks.-Relates to the general construction of a pneumatic jack, which is provided with ratchet or other suitable mechanism to retain it in its raised position. The jack comprises a cylinder a, which is mounted on a footstep b and is traversed by a piston having a rod provided with ratchet teeth e adapted to engage the pawl f mounted on the cylinder. A spring g can be adjusted by sliding it in the casing h, so that it engages the pawl above or below the pivot, and thus retains it in an operative or inoperative position. A valved pressure-supply inlet j, a releasing-valve k, and a vent hole l, also are provided.
