To ALL' WHOM ITMAY coNcEnN:
' Be it known that I, WESLEY B. CAMPBELL, of Abingdon, in the county 'of Jefferson, of State of Iu'a, have invented a new and useful Improvementin Rotary Steam-Engines; and Ido hereby declare that the following is afulLcIear, and exact description of" the same', reference-being liad to'l the annexed drawings, making part of this specification, in whicht v Figure 1 is a perspectiveview, and
Figure 2 is a side elevation, partly in section. W Y Figure?) is avertical transverse scctionof -thecams and part of the case. The same letters in all the figures indicate the same parts.
jMy improvements relatejtthatclass of steam-engines'inv which revolution is comtnunicated toawheel by the'direct impact of the steam pressing against one side of the floats upon the wheel continuonsly and my" invention .consists in tho construction of the vcase and wheel, whereby the'st'eam shall act on the fioats, and not press withits f'ull force against the. huh of the wheel; and also, in the'arr'angement of .the earnsl for actuating the eut-ofi`,which directs 'theaction of the steam against one side of the oats only. A
In the annexed drawings, A is the steam-chest or case, enclosing the wheel, B, which revolves upon journal-srunning on the main frame. The wheel B runs ina chamber in the steam-chest, and is constructed with a-series of radial floats, B', arranged upon its periphery, vagainst which the pressure of the steam act's, to drive the wheel.
The floats areattached tothe hub ofthe-wheel only at their middle portion, b', the ends b Vextending over. the hub, leaving a space between theiloats and the hub `sutricient to receive the flange c ot` the side-pieces C of the steam-chest. These fianges on cach side operate to relievethe hub from the pressure of the steam, rw hieh, entering at D, presses against one side of the oat B', driving it before-it, 'until thcfcat, passing'vthc cductionpipe E, allows the steam to escape.l The ends of the flanges are iitted 4neatlyto 'a central ba'nd on thewrhcel B, to which the floats are attached# I 4 i In order to direct the pressure of the steamngainst one side of thofloatsonly, thofcut-oi valve, F, is arranged in thetop 'of' the steam-chest, standingrvertic-ally, and pressing its point against the hub of the wheel and the top of v the ilanges C C, seas to` separate the steam-chest into twoveompartmcnts.' Itis necessary,\o f conrse,"that this valve should be raiscdwhcn the floats areV passing. This is accomplished by the following mechanism t ,The arms,-G, are attached to tho topet the valvc-stem,and are connected on each side by rods, H, with the cams I, which, being set on the driving-shaft of the wheel B,'arc so constructed as to'raisc the rods H, and with ,them 'the valve F, at the instant the iioats, in revolving, approach said valveclosing again' instantly as s'oon as the floats have passed. Y v i K is a, fly-wheel and pulley, placed on the end of the driving-shaft.
The steam-chest is constructed with two sets of induction-pipes, I), and educton-pipcs, E, placed on oppo site sides of thc valve F, so that by directing the steam into one or. the other side, the wheel may bedrivcn in either direction,'as required.
What I claimas my invention, and desire to` secure hy'Ietters Patent, is
l1. The arrangement of the wheeli'B, floats B,.the cndsb, flanges c, eide-plate'syC, and steam-.chest LA,
whereby torelieve the huh `f'rorn the pressure ofthe steam, substantially as set forth.
42. The arrangement of the wheel B, the valves F, arms G, rods H, and cams Lisubstantially asset forth.'A
I I In testimony-whereof, I have signedmy naine tethisspecificatonin the presence of two subscribing witnesses'.
