George and Albert Raymond's patent "relates to an improved apparatus for converting a reciprocating into a rotary motion, intended more especially for use in connection with the pitmen of windmills. This invention consists mainly in a special combination and arrangement of a walking-beam, cords connected therewith, and clutches mounted upon and having a pawl-and-ratchet connection with the shaft, and in a peculiar arrangement for throwing the pawls into and out of action and rendering them noiseless as the clutches are turned backward."
