rotation of the former produced a corresponding movement in the, 

 latter. Now, between these there are placed a larger (7>) and two smaller 

 toothed wheels (h, i), as well as another toothed segment-piece d ex-

 engages with H, and i engages with the chain-wheel a. The successive 

 transmission of movement is through the toothed wheel i, the lever-
