The cylindersA are fixed to a framing supported on wheels, and the levelof this framing and its angle can be adjusted by means of regu-lating screws. The piston rods of the cylinders A are con-nected to cranks on the crank shaft B^; upon this is a worm gearing into C on the uprightshaft C, at the lower end of which is a mitre pinion C^, gearing into the pinion D^, on thehorizontal shaft D, on which is also fixed the bevel pinion DS gearing into the large bevel 8T1. ?^>,;A^:^V:>si^5?M^:?^^^^^^.
