Abstract
399,597. Breaking-down appliances for mining &c. TONGE, J. and TONGE, K. J., The Grove, Westhoughton, Bolton. June 20, 1932, No. 14311. [Class 68 (i).] Relates to hydraulic breaking-down appliances of the type comprising a cylindrical housing with cylinders bored therein and each containing a sliding cylinder with a solid ram sliding therein. In Fig. 1, each sliding cylinder D has an internal shoulder d limiting the movement of its ram E and each stationary cylinder B has an abutment plate C slid into a slot c to limit the motion of its sliding cylinder D, the latter having a reduced inner end d<2> receiving a cup washer G held by a cap-nut F which also encloses a cup washer H on the ram E. In a modification, each cylinder B is bored through the housing A and has one end closed by a threaded plug. In Fig. 4, each cylinder B receives two duplex rams D, E, moved in opposite directions by fluid admitted through a centre block F<1>. In Fig. 9, a duplex ram D, E, and a solid ram N move in opposite directions.
