US Patent No. 500,852, granted July 4, 1893 to Frank Charcot of Paterson, New Jersey, for an improved Jacquard mechanism. It uses a stationary grate and two sliding griffs moving toward and away from each other, which is meant to increase loom efficiency and reduce wear on the harness. The patent also describes a spring-loaded plate that locks the needles away from the pattern cylinder so the same card stays in place while the operator fixes threads. It includes two sheets of drawings (Figs. 1-4), the specification and seven claims.
