Abstract
246,387. Lichtenberg, J. July 24, 1925. Catch gear of minecage type. -Relates to means for holding in or out of operative position safety suspending devices for mine cages of the kind having a spring-pressed guide engaging roller, adapted to operate the guide grips by means of toothed gearing and right and left-handed screw mechanism. The roller 1 is adapted to engage and be rotated by the guide 19 when the hoisting rope breaks, and through toothed gearing 9, 10 and right and left-handed screw mechanism 5, 6, to force the grips 7 against the guides 8. The roller spindle is connected by a fork 12 to a spring 11. When the rope 18 breaks or becomes unduly slack, chains 16 release L-shaped catches 14 which engage projections 15 on the fork and' normally retain the roller in the inoperative position, so that the spring 11 pulls the roller into the operative position. The roller is retained in the operative position by pawls 20 engaging teeth 22<a> on brackets 22.
