. Mechanical appliances, mechanical movements and novelties of construction; a complete work and a continuation, as a second volume, of the author's book entitled "Mechanical movements, powers and devices" ... including an explanatory chapter on the leading conceptions of perpetual motion existing during the past three centuries. closed by pressing a button, the armature end of the lever B is pulleddown, releasing the upper end of the vertical lever D, which also serves as a hammer, striking the lug on the pawlE, throwing it out of engagement withthe ratchet, thus allowing the shaft of thestop to revolve and close the valve bymeans of the sprocket chain attached tothe sprocket wheel of the stop, engaginga similar sprocket wheel attached to thethrottle-valve stem, the weight on thecable furnishing the power. At the op-posite or right end of the stop is adashpot, which consists of a cylinderinto which the piston P fits closely. On this end of the shaft iscut a square-threaded screw, S, passing through a nut fastened in thecenter of the piston, P, so that as the shaft revolves, by means of this screwthe piston is carried into the cylinder, and the air behind its inner faceis compressed, thus forming a complete cushion. The speed at whichthe stop acts may be very accurately adjusted by turning the by-passvalve V,
