No. 5. ored to exhaust all the different methods by which an au-tomatic cut-off could be successfully operated, the typefinally adopted and which may be seen in all parts of thecountry, being generally one with exhaust valves of theCorliss type under the cylinder and vertical gridiron valvesat the side near the ends of the cylinder released by thesame valve gear below the chest which operated the ex-haust valves. The general features of this system wereembodied in larg-e compound engines after they came invogue, an example of which may be seen in the Jewellflouring mills, Brooklyn. The conservatism of purchasers and commercial consid-erations involving the cost of manufacture, always tendto bring about a certain degree of uniformity in all ma-chinery designed for the same purpose, and this is true of. connected to an 800 dynamo and operating the ConeyIsland & Brooklyn Railroad at Smith and Ninth streets,Brooklyn, N. Y. The cylinders are 26 ins. and 46 x 42 ins. stroke. The engine runs at a speedof 85 Weight of engine is 125,000 lbs.; weight ofwheel, 50,000 lbs. It is to be regretted that the manufacturers have neg-lected to point out the distinctive features of their two en-gines. It will be observed, however, that in the Dixon-Corliss engine all the valves on each cylinder are op-erated from a wrist-plate as in the original Corliss prac-tice, both being- connected to one eccentric. In theWright engine the exhaust valves of each engine are op-erated by one eccentric through independent wrist-platesdropped near the level of the floor and the steam valvesare arranged on the other or crank side of the engineand operated by a separate eccentric and rock-shaft,the motion of the governor being imparted to a longi-tudinal rock-shaft and motion transferred to t
