Abstract

228,020. Brashaw, T. C. H., and Coupe, W. June 19, 1924. Back struts; skid; actuated or applied by speed regulators.-A brake for a colliery tub, truck, &c. adapted to act for either direction of movement of the truck comprises arms D<1> pivoted at B and acting as back-struts or skids according to the direction of movement, these arms having transverse bars D<2>, shown in under plan in Fig. II, which are held up in the dotted line position of Fig. I by latches E having a pin-and-slot connection with a spring-controlled plate F. A centrifugal control N comprises an arm 0 pivoted at O<1> to the axle C<1> and opposed by a spring P. When the speed of the truck reaches a predetermined limit this arm flies out radially adjacent the spring and knocks to right or left a lug K<1>, Fig. II, on a slide K so that one or other inclined edge on this slide coacts with a pin J on the plate F to move the latter downwards, Fig. II, and withdraw the latches E towards each other and so release the arms D<1>.
