摘要： A load support includes an outer tube and a plunger at least partially slidably disposed within the outer tube. Gravity-set wedging members are disposed between an outer surface of the plunger and an inner surface of the outer tube for setting the plunger and outer tube in place with respect to each other, wherein the wedging members are substantially self-setting under gravity. The wedging members gouge the outer surface of the plunger and the inner surface of the outer tube upon inward axial movement of the plunger within the outer tube.

摘要： 638,743. Pit props. SOC. ANON. DES TUBES DE VALENCIENNES ET DENAIN. July 8, 1946, No. 20282. Convention date, June 8, 1945. [Class 20 (ii)] [Also in Group XXX] A telescopic pit prop comprises a tubular hood supporting plunger 4, Figs. 2, 3 slotted longitudinally and normally freely sliding in a cylindrical inner bearing means 9, 10 at the upper end of a tubular standard 1, the. plunger 4 being expanded radially into locking engagement with the bearing means 9, 10 by a wedge 11 forced into the slot 5 by a key 12, the slot and wedge being tapered upwardly. Hoop rings 9 and a tubular spacer member 10 form the inner bearing means which is provided with an extension 3 to house the wedge I and key 12, the latter having a pair of flanges one of which engages a slot in the back of the wedge 11 and the other a slot in the extension 3. Accidental withdrawal of the key 12 is prevented by means of a removable cap 13 and a spring-urged cotter pin inserted in a hole in the key. A pin 21, Fig. 3, freely slidable in a boss 20 on the extension 3 has its upper end in contact with the lower edge of an annular flange 8, Fig. 2, of a pivotal cap 6 and serves to measure the penetration of the plunger. In operation the plunger 4 is first brought into engagement with a roof cross-bar by means of a pair of keys 25, Fig. 5 (not shown), which are alternately engaged in staggered slots 26, Fig. 2, in the standard or alternatively a hoisting device, Fig. 6 (not shown), (see Group XXX), may be used.
