Abstract
845,322. Mining machines. EICKHOFF MASCHINENFABRIK UND EISENGIESSEREI GEB. Nov. 25, 1957 [Nov. 28, 1956; Jan. 5, 1957], No. 36593/57. Class 68(1). A drum type cutting machine in which the drum 5 is rotatable in opposite directions and is provided with cutting tools 13, having oppositely directed edges 18 and 19, the tools being arranged to pivot with respect to the drum 5 through limited paths. A pick 13 is mounted in a holder 11 secured to a pin 10 and has a tail 12 engaged in a notch 9 in the external surface of an internally toothed gear ring 7, which is coaxial with and free to rotate relative to the drum 5. The ring is driven by a pinion 8 and when the direction of rotation of the pinion is reversed, the holder 11 pivots in the rectangular opening 17 until its movement is stopped by one of the edges 20 and the whole drum then begins to rotate. Tugs 14 on the tool-holder close the appropriate part of the opening 17 to prevent cut material entering the mechanism. In the example shown each pick is mounted in a separate holder keyed to the pin 10, only one holder being driven from the gear ring 7. In a modification the picks are mounted in a single holder of suitable length which is free to pivot on the pin 10, which is fixed in the walls of the drum.
