This mechanical saw works with hydraulic energy. Thanks to a complex system of cog-wheels, which combines the rod and crank with the pawl mechanism, the hydraulic wheel transmits the alternated motion to the saw and to the trolley transporting the logs. This is synchronised to move forward one unit at the time. The functioning of the saw is thus made as automatic as possible.
The model is based on the drawing:
