Abstract

614,865. Mining - machines. MUSCHAMP, N. J., and COWLISHAW, F. Aug. 8, 1946, No. 23491. [Class 68 (i)] Relates to pick boxes for coal cutting or other mining machines of the chain type. In Fig. 1, a chain link 1a has spaced side lugs 6 between which is mounted a cutter 8 with radial teeth 9 adapted to be brought successively into operative position; the cutter has an integral axle 15 received in slots 16 in the lugs 6, and is retained by a pin 11 inserted in either of two holes 12, according to the direction of cutting, the ends of the pin being bent over into slots, and rotation of the cutter being further prevented by contact of an idle tooth 9 against an abutment 14. In Fig. 5, a three-pointed cutter has a hexagonal axle 15a and is held against rotation by contact of an idle tooth against either of two abutments 14a. In Fig. 6, the cutter has a removable cylindrical axle 15b held by a bent-over pin 18, the axle being interchangeable with the hinge-pins 2 connecting the chain links.
