To all, whom, it nagy concern. the products of combustion from the combus Be it known that I, WILLIAM EZRA WoR tion chamber also being carried upward and THEN, a citizen of the United States, residing through the stack.

At the the front end a movable scoop 30 connected forward end of the boiler is the usual smoke by a rod 31 with the engine cab so that the 35 box X and into this chamber extends the ex engineer by lowering the scoop 30, when the haust tubes, terminating in the exhaust noz engine is in motion, can cause a stream of zle B, a branch 5 of which communicates with water to pass upward through portsy covered a condenser D. As shown, the condenser is by the flanges of a cap valve 15, which is 90 in the form of a hollow cylinder or receptacle raised by the force of the Water, and into the having side openings a communicating with receptacle 8 within the smoke-box. This re the smoke-box, and adjustable ring Valves for ceptacle 8 communicates through a pipe 7 regulating said openings and the condenser with the upper portion of the condenser D communicates at its lower end with a pipe 10, above the nozzle l4, and when the valve 12 is 95 constituting a discharge pipe, and is con lifted, its lower tapering end which closes the 45 tracted at the upper end and provided with a contracted portion of the condenser, or upper nozzle 14, which is closed by the tapering end end of the nozzle 14, will be raised to permit 13 of a valve I, a cylindrical portion 12 of the the water to flow from the chamber 8 into the valve fitting an opening in the branch 5 and condenser, meeting both the steam and the OO acting as a valve for a port v between the smoke, and condensing the steam and pre 50 branch 5 and the condenser D.
