Abstract

856,702. Retarding articles in shoots. WALTHER, M., and PRETZSCH, J. Feb. 5, 1959, No. 4145/59. Class 78 (1). Pit props are dropped down mine shoot 1a and retarded as they travel round horizontal track 1, being discharged at one of the stations 4. A plurality of such tracks may be provided at a plurality of levels, the individual tracks being fed by a portion 5 (not shown) of the shoot which is caused to pivot to divert the prop to the individual track by a fluid-pressure or solenoid device.
