Abstract

886,642. Mineral-mining machines. ALLIMANN, G. Aug. 31, 1959 [Sept. 27, 1958], No. 29680/59. Class 68(1). Pivotally mounted in peripheral recesses 4 of a cutter disc 1 for a cutter unit of a mineral-mining machine are swinging picks 2 that, on being thrown back into the recesses on encountering the mineral. being mined, compress springs 8 housed in the recesses so that the springs exert forces in addition to centrifugal forces to cause outward swinging of the picks as soon as possible to deliver the next blow.
