Abstract
7557. Williams, W. S. March 26. Winch-actuated lever load-handling appliances. - Comprises mechanism, particularly adapted for use in pickling metal plates, in which the plates are lifted and lowered through a fixed range and reciprocated while in the pickling-bath by ratchet gearing operated by a constantly-running motor, the raising and lowering being automatically stopped when the limiting positions are reached. The motor shaft drives a crank-disk A, which reciprocates an arm C through a rod B, the arm being mounted loosely on a shaft D and carrying a weighted pawl E which engages a ratchet-wheel K. The ratchet - wheel is connected to a rope pulley, round which a rope passes to a beam from which the cradle H is suspended. The pawl E and a retaining-pawl L are adapted to be put out of gear once in each revolution, when desired, by a sliding cam M on the crank-shaft acting through rods and levers which are connected to the pawls through springs R, S, so that the pawls can only be raised when there is no load on them. To lift the cradle, the cam is moved to its inoperative position, and the ratchetwheel is rotated tooth by tooth, the space between consecutive teeth being a little less than the stroke of the pawl E. One of the ratchet teeth is masked by a raised plate S, so that the pawl E cannot drop into it, and lifting is automatically stopped. When the cam is moved along its shaft into its operative position, each pawl is raised once for each revolution of the crank-disk and the ratchet-wheel rotates tooth by tooth under the action of the load. The lowering- action is automatically stopped when the tooth preceding a tooth X is acted on by the pawl E as the tooth X is widely spaced so that the pawl E cannot reach it on the down-stroke, and the retaining-pawl cannot be lifted as it is supporting the load. When the cradle is in the pickling-bath or at any position it can be reciprocated through a small range by moving the cam so that it operates the pawl L only. The cradle is then reciprocated by the movement of the pawl E.
