TO A LL WHOM IT *MAY CONCERN:
, Be it. known that I, WESLEY B. GAiiPnnLr., oi' Abingdon, in the county of Jefferson, and' State oflows, have inizented a new "and useful Improvcinentin Rotary Steam-Engines; and I do hereby declare that theffol.. lowing is a full, clear, and exact description of the saine, -retei-encebeing had tothe annexedA drawings, making part of this specification, in which- Figure 1 is n perspective view, and Figure 2 is averticnl longitudinal section. Y 'Tho'sauxe letters are employed in hoth figures in the indication of-the same parte. f i l My invention relates to .thatelass of engines in which the steam is applied directly to iloats'nponfa wheel,
. to which a rotary motion is communicated, and the character of my improvements will be fully Vsctiorth in the following specification and claims. l 7
A is the induction-pipe, through whichlthe steam is conveyed from the steam-generator to the rotary wheel. ,B isfa metallic cas'c, enclosing the wheel, which run's in a recess in the lower'part of the case.' .The wheel C .is a solid metallic disk, turning on a shaft, having suitable bearings on a frame, andearrying a y-wheelpulley.
The periphery of the wheel is formed by a sc rics of four er more eccentric-faces, as shown in iig. 2. The points i of these faces run in. close proximity to 'the innersurface of the semicircnlnrchainbcr inthe case, to prevent` t Steam O Wng from one 0f the. compartment-Ss formed 'between the eccentric-faces' and the'ease, nto another. An are of Babbit metal is s et into lthe side of the recess in the casing, which, 4by ineens of set-screws', maybe eempressed'agnins't the side of the disk C, to form a steam-tight packing, and prevent the escape of the steam 'over the sides of the disk, through the spnce'bctwecn theinduction and eduction-pipes 'lhe steamentering through the induction-pipe presses with its full expansive force against the vertical side of the chamber formed by the eccentric-faces, driving the wheel forward towards the edu'etion-pipe G, through which the steam escapes. The back pressure of the steam against the inclined eccentric-.facesof the disk is prevented hy'a valve, E, which fills th'e chamber between the wheel `and the case. Asthe wheel travels forward, this valve is forced .np by the inclination of' the eccentric-face into a recess cut in the case, When the -point passes from under it, it is instantly forced down by the spiral spring F. The expansive force ofthe steam., backwards being expended on this valve, its full force is directed towards the vertical face, the steam acting expnnsivcly, untilA that chamber is cut oil' by another receiving the steam, when the steam -is permitted to escapey 4through the pipe G.; Y i
` The cap, Bgis forined and packed like the ordinary steamchest. B2 is a smiling-box, through which th ralve steam passes. y i
In order that the engine may bo made to ran in eitherdirection, a second 'wheelis .placed on the same shaft; the inclined faces of which are reversed, the case being formed'by an addition tothe one shown,so as to duplicatet-he recess. Then a branched steamfpipe is employed, se that the steam may be directed upon either wheel, as it may be desired to have the shaft revolvein one drcctioner theother. rlhe enseis s'et upon the heads of the frame, resting upon India-rubber springs, and secured b'y bolts, so that asth'etpoints of the wheel are worn from long use, the case may bc drawn down to maintain the tightness l of the jointsllhe pressure for driving this wheel may be derived from steam, water, or any other fluid capable of such application. Y
What I claim as'my invention, and desire to sec'ure by Letters Patent, is The arrangement of the following partis:V The induction-pipe A, the case B,wheel C, packing D, valveIE,` s'prinfor F, and eduction-pipe G, substantially as set forth. i
In testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
