"Vintage Machinery" entry for E. & B. Holmes
Description:
The nature of oar invention consists, in combining in a windlass, a friction-driving pulley, to prevent any injurious or breaking strain being brought upon the truss-rope or windlass, and a clutch-coupling to the windlass drum, so that the drum may be readily disengaged and reversed to unwind the truss-rope therefrom, whereby the windlass is specially adapted to apply engine-power to trussing of casks.
