Abstract

855,670. Advancing mine props or chocks. EGGEMANN, W., and CAMPENHAUSEN, E. VON, [trading as SCHWARZ KOMM.-GES. H.], May 22, 1957 [June 19, 1956], No. 16212/57. Class 20(2) [Also in Group XXX] Hauling means for withdrawing, erecting or displacing mine props &c. 1, Fig. 6, by a rope or other flexible hauling element are mounted on the framework of a face conveyer 9. In one form, Fig. 2, the hauling means comprises a winch drum 3 journalled in a frame which is either secured to the framework of a scraper face conveyer or, as shown, provided with rollers 12, 13 by which it is guided for movement along the conveyer framework. The winch drum is driven by an internal compressed air motor controlled by handle 8 Alternatively, as in Fig. 4, the winch drum may be driven by engagement of a sprocket 16 with a chain 24 of the face conveyer, the sprocket 16 being connected with the winch drum through bevel gearing, or by engagement of a star wheel 17, Fig. 5, with the scraper bars 18 of the face conveyer. In another form, Fig. 6, the hauling means comprises a sheave 20 on the conveyer framework and a rope 4 which is secured at one end to the mine support 1 and extends around the sheave 20, the other end of the rope 4 being provided with a hook 21 adapted to be engaged with the chain 24 or with a passing scraper bar. The hook 21 includes a lug 23 adapted to ride up a cam surface 22 on the conveyer framework to automatically disengage the hook 21 after it has moved a predetermined distance. The conveyer is advanced by a cylinder 10 and a sprag 11 engaging the roof.
