. 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. upon the chisel is so rapid as to be almost con-tinuous. A small balance wheel on the end of shaft A absorbs partof the shock of the impact and produces smooth running. A plunger,D, is free to sHde within the hammer head, but is kept from strikingpoint F by the coil spring at E. When the pitman moves to the rightits right-hand end presses against the plunger at G, which in turn com-municates motion to the hammer head through spring E, and the chiselis struck a sharp blow. After the blow, the hammer head is returned by the movement of thepitman to the left, by means of pin g. This pin is attached to hammer-head C, but is entirely independent of the plunger D. The end of thepitman is slotted to receive pin g, and the slot is of such a length that thepin, together with the hammer head, can have free motion during theblow. 854. DUPLEX ROLLING LIFT BRIDGE. Scherzer bridges cover a double waterway of no feet each, over NewarkBay, on the line of the Central Railroad of New Two 75-horse-power gasoline engines, manufactured by Fairbanks,Morse & Co., are provided. Each engine is so arranged and con-nected with the machinery that it can operate both bridges eitherjointly or separately, as desired. The operators house is constructedentirely of steel and fireproof material, wood being eliminated. ENGINEERING AND CONSTRUCTION, ETC. 331 855. BALANCED SWING BRIDGE, Toronto, Can.
