ROTARY FLUID-ENGINE.

SPECIFICATION forming part of Letters Patent No. 748,348, dated December 29, 1903.

' Application filed June 16, 1902. Serial No. 111,810. (No model.)

To all whom it may concern:

Be it known that 1, JOHN FRANCIS CooLEY,

otBoston, (Allston,) in the county of Sufiolkr" cylinder with diametric internal projections which rest upon the periphery of the spacer, the said cylinder acting as a valve-piece in relation to said ports whereby the ports are brought successivelyinto com mu nication,and

2o exhaust-chests for propelling or being propelled by fluids--in other words, rotary fluidengines which may be operated by internal devices to produce pressure in the fluid medium and, conversely, which operate in con z5 sequence of pressure in a fluid medium to give motion to external devices.

My invention consists of certain novel features hereinafter described, and particularly pointed out in the claims.

3o Inthe accompanying drawings, which illustrate aconstruction embodying my invention, Figure 1 is a central longitudinal sectional view through the engine on the line 1 1, Fig. 2. Fig. 2 is a cross-sectional view through the engine on the line 2 2, Fig. 1, looking in the direction indicated by the arrow.

Like letters of reference refer to like parts throughout both views.

Referring to Fig. 2, steam or other fluid is admitted through the opening A into the pressure-chest B within the cylinder A and passes through the port 0 in the spacer L into the space D, pressing upon the piston E between the shoes F and G, the resultant of 5 which pressure passes below the axis of revolution P of the piston E, thereby causing its rotation in the'direction of the arrow. In other words, the distance on the radial line between the center or axis P to the shoe F is less than the distance between the axis P and 5c the shoe G, making a preponderance of pressure below the axis P and causing its revolution in the direction of the arrow, as above stated, which continues until the shoe F and the shoe Goccupy positions corresponding to the present position, Fig. 2, of the ports C and H, when the radial distances of the shoes F and G from the center of revolution P of the piston E are equal and the port C is in position over the valve-piece packing-strip I and the chamber D is about to exhaust into the chest J, from which the steam exhausts. through the opening K, the spacer L having rotated in the same direction as the piston E, but at a slower speed, and whose relation in integral numbers may be expressed as two to three in complete revolutions of both parts. The shoe M, occupying a point corresponding to the valve-piece packing-strip N, would thus be in a position which, measured upon a radius drawn from the center of revolution P of the piston E, would be shorter than the distance from the center of revolution P of the piston E to the shoe F in its moved posi tion, which would correspond to the present position of the port O, (shown in Fig. 2,) making the preponderance of pressure to the right of the center of revolution P of the piston E and causing rotation in the direction of the arrow, theport 0 then communi- 8o eating with the pressure-chest B and allowing the fluidto enter from the chest B to the space R, and the operation continues as above described. The pinions P mounted on the shaft P of the piston E, and the internal gears L, out in openings in the disks L secured to the spacer L, intermesh and operate at the same correlative speed ratio as thepiston and spacer of the engine. The rings S and T, (shown in dotted and section 0 lines, Fig. 1,) and of which one, T, is shown in dotted lines, Fig. 2, are provided to pre vent internal leakage to or from the chests. The wearing-rings L are provided with radial projections (shown in dotted lines, Fig. 2) and are located in the two opposite end disks L as shown in section in Fig. 1. On the outer ends of the engine are located the cylinderheads U, through which project the shaft P of the piston E, and which cylinder-heads have also inwardly-projecting hubs U, which form a bearing for the hubs L on the end disks L of the spacer L and also for the shaft P. The spring-pressed va1ve-piece packingstrips N and I are located Within the two diametric internal partitions N and j, as shown, and said strips and partitions rest upon the periphcry of the spacer L which is in continuous contact with the periphery of the piston E at points situated at radially-equal distances from the axis of their rotation Q, which is the center of rotation of the spacer L. The shoes F, G,an'd M rock, respectively, in springpressed splines f, g, and on within recesses in the spacer equidistant from each other. The entrance and exit ports 0, H, and O for fluid are laterally situated in the periphery of the spacer L and preferably intermediate between the points of contact of the spacer upon the piston.

Having thus described the nature of my invention and set forth a construction embodying the same, what I claim as new, and desire to secure by Letters Patent of the United States, is
