The machine includes: drive transmission means which permit reversal of the direction of rotation of the drum without having to reverse the prime-mover, the drive transmission means being interposed between the driving means and the prime-mover driven shaft and comprising: two gear wheels, the gear wheels being mounted for continuous meshing engagement with one another on parallel shafts, one of the shafts being operatively connected to the prime- mover driven shaft for continuous rotation of the gear wheels in opposite directions about the shaft axes; and a cradle, both of the shafts being rotatably mounted in the cradle, the cradle being pivotable about an axis parallel with the axes of rotation of the gear wheels; the cradle being adapted selectively to move each gear wheel into and out of a position in which its rotation is transmitted through the driving means and the driven means to rotate the drum in one or the other direction. By this invention, then reversal of the direction of rotation of the drum can be effected without reversing the prime-mover.
