Abstract
221,917. Williamson, J. A. July 21, 1923. Catch gear of mine-cage type.-A horizontal frame J is connected to the ring K on the hoisting rope by a chain L and supports a series of vertical rods F which are slidably mounted in bearings G on the side of the cage. Links M connect the rods F with tapered guide-engaging members B which are pivoted at their upper ends in a movable block C and are forced into engagement with the guides when moving upwards by a fixed casing A. Stops O ensure the action of the gripping device. Springs P may be provided for accelerating the downward movement of the rods F when the hoisting rope breaks. Each pair of grips B may be connected by slotted links Q.
