Leath′er-roll′ing ma-chine′.

A machine to compress and harden leather, instead of hammering it. The journals of the lower or pressure roller are mounted in a movable lever frame, which is provided on the under side of either end with projec- [1280] tions resting upon joints, which are supported upon the central portion of a cross-piece in the main frame, in such manner as to operate with the lever frame like a toggle-joint, in addition to the usual compound lever employed for moving the pressure-roller.

In another machine, the skin of leather is placed on the table, which is raised more or less by togglelevers, to regulate the pressure of the roller. The roller is journaled to a slide reciprocated by connection to a crank. The tool is a steel roller or glass edge.
