Abstract

179,781. Luevano, J., and Anduaga, S. April 8, 1921. Catch gear of mine-cage type.-A cross-bar D freely movable on guide-rods G in a housing A attached to the top of the cage B is connected to the hoisting-rope and has sprags I pivoted to its ends. When the rope breaks, the bar D falls and the ends of the sprags are projected through apertures in the housing into engagement with the wooden guides M. The descent of the bar is assisted by springs K, L. The guides M are prevented from splitting bv channel irons N mounted on the cage.
