Abstract
850,915. Mineral mining equipment. JOY - SULLIVAN Ltd., and BALL, C. F. June 26, 1959, No. 22041/59. Class 68(1). To allow of a cutter head to be tilted about an axis transverse of and longitudinal of the mobile head - supporting chassis there is incorporated in the transmission drive to the cutter means of the head a universal coupling 27 that lies on the centre of the transverse axis and therefore also on the above mentioned longitudinal jacks acting between the chassis and the cutter head control movement of the cutter head about said axis. Specification 811,940 is referred to.
