Abstract
126,207. Griffin, W. July 8, 1918. Catch gear of mine-cage type.-A casing a is fixed preferably to the top of the mine cage &c. adjacent to two or more of the guides and has an inclined extension c adapted to enclose a wedge d pulled downwards by a spring j and having lateral grooves o engaging with corresponding ridges on the casing extension which take part of the thrust. The wedge is put into operation, on breakage of the cage rope. by a spring m pulling down a lever l connected by a link k to a lever f mounted on pivots g and having a cam-shaped end e acting on the wedge. When timber guides are employed, a. pair of wedges with herring-bone ridges on the working faces are arranged at opposite sides of each guide.
