The weight of themoving parts, 10 cwt., gives a total of 2240 units of work, whichis equal to the force exerted by a weight of 1 ton falling througha height of 1 ft.; but by admitting the steam to the top side ofthe piston, and so accelerating its descent, the force of this blowmay be considerably increased. This hammer is so proportioned in the various parts, that allare equally strong, and in order to facilitate the carrying out ofany necessary repairs the parts are made as accessible as pos-sible; the repairing of a steam hammer generally occasioning. iDQ am cni 1389.
