The springL throws back the lever/, the rod D. and the valve G totheir former places in such a way that the movement ofthe hammer is carried on without shock or concussion. J/(fig. 77) is a lever at the side which serves to regulate the stroke of the piston ; when placed at n the lever M raises the lever J through the shaft on which the latter I oscillates ; in this case the piston has only a short stroke, I and if this lever is placed at/ the piston rises to the full. riiew-^af^j- ifif*w:
