Abstract

142,192. Withers, J. S., (Rosser, W. J.). Jan. 29, 1919. Sustaining at limit of wind. - One or more pawls d, or racks, are carried by the vertical portions of the supporting straps c of the cage and engage racks g, or pawls, mounted at the upper end of the shaft only, in the case of an overwind and failure of the safety hook to arrest the descent of the cage. The pawls d may be mounted on shafts a which can be rotated from within the cage to place the pawls in engaging position. Springs h maintain the pawls in position for engagement.
