Abstract
119,415. Holmes, D. W., and Lewis, H. J. April 24, 1918. Catch gear of mine-cage type.-A wedge-action safety-suspending appliance for supporting a mine cage &c. in the event of the winding-rope breaking is shown in the drawing. A lever c<1> pivoted on the top of the cage is connected at one end to the winding-rope ring d and at the other end through a rod e<1> to a wedge f slidably arranged in a block f<1> on the side of the cage and adjacent to one of the guides i. The wedge is normally kept cut of action by the pull of the winding-rope and by an inclined stop j on the cage. If the winding-rope breaks, the weight of the lever c' &c assisted by the pull of a spring h connected by a pivoted lever g<1> to the wedge raises the wedge to grip the guide.
