SPECIFICATION forming part of Letters Patent No. 782,045, elated February '7, 1905.
Application filed May 16, 1904. Serial No. 208,084.
have invented certain new and useful Improvements in Engines, of which the following is a specification.
.\ly invention relates to steam-engines; and
the object of the invention is to utilize the exhaust-steam, which is usually discharged into the open air and wasted, for operating a secondary or auxiliary engine located at any suitable distance from the primary or highpressure engine to develop power for running a pump or like apparatus.
The invention consists generally in utilizing the exhaust-steam of a high-pressure or primary engine to operate a secondary engine having a piston of the revolving type that is independent of the piston ot' the primary engine and operated at the same or a greater or less speed.
ln the accompanying drawing, forming part of this specification, the figure represents a longitudinal section of a turbine-engine having its intake-port connected with the exhaust-pipe of a high-pressure or primary englue, said exhaust-pipe being also arranged to discharge into the open air, and a condenser connected with the exhaust-port ot'the turbine.
In the drawing, 2 represents a steam-engine ot the ordinary reciprocating type, having a cylinder 3, provided with an exhaust-pipe at. A T-pipe 5 is connected to the pipe 4, and a pipe (3 leads from said T-pipe to the open air. This pipe, which may be provided with a regulating-valve, (not shown,) is adapted to dis charge into the atmosphere the surplus steam not used by the turbine. A second pipe 7 is connected to the opposite end of the T and leads to the intake-port 8 of a turbine-engine J. This turbine is of the ordinary type, having a shaft 14) and vanes 11 secured thereon and movable therewith and fixed vanes 12 alternating in position with the movable vanes. The vanes are arranged in alternate sets, one stationary and the next movable, and there may be any suitable number of them. The turbine is provided with the usual regulating and throttle valves. (Not shown.) I preter in this case where exhaust or low-pressure steam is carried through the turbine to increase the number of vanes, and thus provide a greater number of deflecting-surfaces. Intake and exhaust chambers 13 and 1t are provided in the ends of the turbine, and an exhaust-port 15 is connected through a pipe 16 with an ordinary jet-comlensor '17, having an intake-pipe 18 and a discharge-pipe 12) leading to the sewer-pipe 20.
The operation of the apparatus is as follows: The steam discharged from the exhaustpipe is usually about or a little above atmospheric pressure,and a portion will pass through the pipe 7 into the chamber 13 and from thence pass the vanes to the exhaust-chamber 14. The operation of the condenser will produce a vacuum in the exhaust-chamber, and the steam rushing through the turbine from the chamber 13 to destroy this vacuum will impingealternately the sets of lixed and movable vanes and being deflected from one to another will impart a rotary movement thereto and revolve the turbine-shaft, which is coupled in the usual way to a generator or other apparatus.
The turbine can be made of any suitable size to provide the desired number of vanes and can be operated at the same or a higher or lower speed than the primary engine, according to the character of the work to be performed. The turbine may be located at any desired distance from the high-pressure engine, and its piston is not in any way dependent upon the movement of the highpressure cylinder-piston, and the speed of one engine will not have any etl'ect on the speed of the other.
The turbine used in this case as a low-pressure engine will generally be employed to operate a pump or similar apparatus, but may be utilized for running other machinery as well, the speed of the turbine depending upon the vacuum, the number of vanes, and the volume of the exhaust.
1 have shown and described my invention applied to one type of turbine-engine; but I do not wish to conline myself to this application, as the invention is equally well adapted for use with other styles of turbines and also with engines of the rotary type.
pendently of the piston of the first-named engine and provided With intake and exhaust ports, a pipe leading from said exhaust-pipe to the open air and to the intake-port of said second engine, and a suitable condenser connected With the eXhaust-port'of said second engine.
In Witness whereof I have hereunto set my hand this 13th day of May, 1904.
FRANK M. OVERHOLT. In presence of* RICHARD PAUL, M. HAGERTY.
