Abstract

244,663. Muir, J. C. July 4, 1926. Addition to 234,012. Catch gear of mine-cage type.-The ends of the levers E, F of the parent Specification are formed as knife edges Q, R to engage the guides X, Y. A bolt I passed through a slot G<1> near the outer end of each lever is connected by chains M, N to the cage and secured to sleeve G. A spring V is placed between the ends of the sleeve and an abutment on the lever. When the hoisting rope breaks, the spring Z forces the knife edges Q, R into the guides and the springs V force the sleeves against the guides. Links S, T connect the levers E, F to a link U attached to the hoisting rope. The levers, &c. may be duplicated.
