Abstract

240,722. Gerrard, J. W., and Gerrard, H. March 6, 1925. Catch gear of minecage type. - Minecage catch gear of the kind having guide-rope engaging devices, has those devices formed as three-armed levers d mounted on pivots d<1> on the side of the cage, one arm d<2> having a slot through which the guide rope passes, the second arm d<3> having a bevelled, jagged or toothed end and the third arm being connected by a chain &c. e to the haulage rope and being normally kept out of action by a spring f or weight. When the haulage rope breaks, the slotted arm kinks the guide rope and the pointed arm engages with it.
