Abstract

942,471. Hydraulic pit props. W. EGGEMANN, and E. VON CAMPENHAUSEN, [trading as HERMAN SCHWARTZ KOMM.- GES.]. March 22, 1960 [March 23, 1959; May 23, 1959], No. 10031/60. Heading E1E. [Also in Division F2] An hydraulic pit prop is made up from a number of units each consisting of a rubber ring 10 bonded to steel plates 23, 24, the units being bolted together and to a control ring 27 provided with inlet, exhaust and relief valves, see Fig. 3 (not shown). One plate of each end unit comprises a flanged base or roof support element. In a modification, Figs. 1 and 2 (not shown), the prop consists of alternate layers of rubber and steel rings bonded together, one ring acting as a control ring and each end ring as a roof or base plate.
