Abstract

249,718. Tennant, T. M. July 7, 1925. Catch gear of minecage type. -A number of claws 9 pivoted on the sides of the cage 1 engage front and rear walls 2 of the shaft when the hoisting rope 3 breaks. The claws are disposed between the side 11 of the cage and a false side 12, and are urged outwards by a leaf spring 18. The inner end of each claw engages a buffer 17 when the claw is in the extended position.
