GHESTER B. TURNER, OF GRAND RAPIDS, M ICIEIIGAN.
Letter-s Patent No. 74,172, dated .February 4, 1868.
IMPROVEMENT IN ROTARY STEMYI-ENGINES.`
@its .rinhnlt referat tu intime tettett @anni mit mating met nt its sume.
TO ALL WHM IT MAY CONCERN:
Be it knownthat I, CHESTER B. ITURNER, of Grand Rapids, in the county of Kent,^and Stateof Michigan, have invented a new and improved Rotary Steam-Engine; ,and I do hereby declare that 4the follownggis' a full, clear, and exact description thereof', which will enable those skilled in the art to make and use the same, reference being had tothe accompanying drawings, forming part of this specification. I f
This invention relates to an improvement in rotary steam-engines, and consists i'nfconstructing the piston with small steam-chambers or recesses `upon its face, said chambers being divided -by partitions or gates, which, togetherwth the recesses, are arranged to operate irl-connection with tho-inductien-port and valves, as will be hereinafter more fully described.
Figure l represents a vertical section ofthe engin-e through the line :csc of fig. 2.
Figure 2` is a section through the liney y of fig. 1.
Similar letters of reference indicate corresponding parts.
A is the cylinder of the engine. B is the piston-core or centre, which is attached to the driving-shaft'C'. D D represent wings or valves, which are loosely hinged to the centre B. E represents an annular spiace,V between the piston-core B and'the inside of the cylinder. To this annular space thestcam is admitted, 4where it operates upon the wings, thereby imparting motion to them and to the rnaiu shaft CL F is a double-earn 4 block, which fills the annular space E, the central portion of which conforms in shape to the piston-core, forrn'ingr-` .a steam-tightjoint therewith, as seen in the drawing. From this central portionyit slopesrat each end to a point," i,
forming cams, which, in the rotation ofthe piston, close the wings alternately as they pass. The steam-orice is seenl at g. The steam-ports (one'for each wing) are marked 7L la. z' z' represent small steamchamber'sj'f'or,
recesses made in the piston-core. These separate'chambers are divided by partitioi'isglln J, .which `cuthcifjthe steam at the desired points, as the piston with the wings revolves. Y i L Wfl The piston is supposed to be moving in the direction of the arrow. When one of th'echambers is incommunieation with the orifice y, that wing is taking steam through its portt, and it-will be seen that, byipirope'rly arranging the 'partitions J, or by making them broader ornarrower, the steam cau be cut oil' at any desired point in the stroke or revolution, and act by its expansive force. i A K is the exhaust-port. When one of thewings, D, has passed the exhaust-port, and is closed by the cam5, as seen in the drawing, the steam is exhausting behind the other firing, D. When the chamber i comes into communication with the steam-orifice g, the wing D .will hetaliing'V steam, and so on alternately.` The wings lor., valves D D are attached to the piston-core, so as to drop into their respective cylindrical recesses lgl, where:
they turn as on a hinge. Behind each wing, it will be seen that there is a lip or. sta-y, @which supports the` 'wing as itis thrown back bv the steam, and after-*friction with the cylinder has reducedthe wing in width somewhat.
Having thus described my invention, I cla-im as new, and desire to secure byLetters Patente The piston B,'provided with the partitions J and chambers i, and arranged to operate in connection `with the induction-port g and valves D and D', as herein described and represented.
CHESTER B. TURNER.
