ABSTRACT:
Coal is pounded in a pounding box to form it into a cake which is then introduced into a coke oven. The pounding is effected by members that are repeatedly lifted and then allowed to drop onto the coal in the pounding box. When the coal is thus formed into a cake, the members are retained in lifted condition by a locking-cam mechanism so that the cake can be pushed from beneath the members.
