Said member 1, is also formed with the encircling peripheral flanges 14, upon both faces thereof, to which are secured by the bolts 65, the casing members 15, and 16, by their flanges 17, and 18.
\Vithin the casing 16, and rigidly secured upon the shaft 4, by cent to the intake side of the member 1, is mounted the rotating compression member 20, which is formed on its periphery with the flange 21, which is provided with a ball race 22, coacting with a ball race 23,formed in the flange 18, of the casing 16, and provided with the balls 24, forming a frictionless bearing for said member 20, to revolve upon within said casing 16. Said compression member 20, is provided with a compartment 25, having a central intake opening 26, in the end thereof, and surrounding the shaft 4; and within said compartment 25, is mounted a radial bladed combined suction and forcing fan 27 which is secured upon a sleeve 28, which is rotatably mounted on the shaft 4; and which extends out through the end of the casing 16, and which is adapted to be rotated by a pinion 29, secured on the end thereof; said pinion 29, being driven by a gear 30, which is rotatably mounted on a shaft 31, secured in the bearing bracket 32; said gear 30, being integral with a pinion 33, which is, in turn, driven by a gear 34, which is keyed to the shaft 4, and adjacent to the pinion 29; said train of gears as here shown being of such ratio, that the suction fan 27, will make four revolutions to one revolution of the compression member 20, and this ratio may be varied as desired. The compression member or ring 20, has a fanshaped opening 35, extending from side to side of said member 20, and for about onethird of its circumference; and this opening 35, is provided with stationary dividing shutters 36, set at an angle of about fortyfive degrees, for the purpose of breaking up and mixing the charge of gas as it is forced through the opening 85, by the fan 27, the remaining portion of the compression member 20, having the side wall 37, which affords a temporary side for the explosion chambers 8, during the period of explosion, as will hereinafter be more fully explained.

The impulse receivi'ngmember or driving rotor 61, is also keyed upon the shaft 4, upon the other or outlet side of the member 1, and is formed with a similar bearing flange'44, ball race 45, and balls 46, running in a corresponding race 47 formed in the flange 62, of the casing 16. Said driving rotor 61, is
formed with the end wall 49, and the inner wall 84, which are connected together by the hub 50, and the wall 51; said rotor 61, being also formed with a fan-shaped opening 52, extending through the same, near the periphery thereof, and extending for about one-third of its circumference; said opening 52, being provided with a series of curved blades 53, which are set at an angle and extend downward by the side of the outer wall 49, and which are designed to re ceive the impact of the exploding gas from c the explosion chambers 8, and thus be rotated thereby; said exploded gas being then expelled by the curved ends 54, of said blades 53, into the chamber 55, and then out of the exhaust port 56, formed in the casing 16; a cone-shaped deflector 57 being employed to keep the gas from the bearings of the shaft 4, the Wall 48, serving as a temporary side for the explosion chambers during the period of compression, and being timed to move out of the way of the force of the explosion at the instant of the ignition of the charge, so that the full force of the exploding charge will be against the blades 53, which have taken the place of said wall 48. Between the adjacent surfaces of the member 1, and the rotor 61, is also placed a gasket 58, similar to the gasket 38, and retained in, a like manner in the groove 59, and under compression of the springs 60.
The cooling of the compression member 20, and the rotor 61, is effected in the following manner :-Between the inner and the outer walls of said members is formeda compartment 66, which extends entirely around said members, except where closed off from the opening 35, by the wall 67 the outer walls of these compartments which are also the periphery walls of the members 20, and-6 1, are provided with one or more openings 88, through which air will circulate from the space between said members 20, and 61, and their respective casings 15, and
revolved, the ch igo'mm 16;;said casings 15, and 16, being formed with a series of'openings 69, for the admission of'said air. The end of the casing 16, is provided with an intake chamber 70, opening into the compartment 25, member 20; and is formed with anintake port 71, to which is connected 72 anda controlling means 74, and fed by feedpipe 75, from shown).

5- A compression means for rotary gas engines comprising in combination with a stationary member formed with a series of explosion chambers, each provided with ignition means, and a driving shaft rotatably mounted in axial relation to said stationary member, a compression member secured upon said shaft adjacent to said stationary member, and adapted to be rotated by said shaft, said compression member @rmed with spaced side walls joined together by a hub and a rim, and having an opening extending through the sides thereof, blades secured within said opening and set at an angle, a suction and forcing fan mounted adjacent thereto and adapted to deliver gas to said bladed opening in said compression member whereby it is compressed into the explosion chambers, means for providing a temporary side wall for said explosion chambers during the period of compression, and means for providing a temporary side wall for said explosion chamber during the period of ignition.
6. A compression device for rotary gas engines comprising in combination with a stationary member having a series of-cxplosion chambers formed therein communicating with a rotating shaft driving member, and a casing secured to said stationary member and provided with a carbureter, a rotating compression and suction fan mounted upon the driving shaft, within said casing and adapted to draw the gas from said carburetor, a double walled compression ring mounted within said casing upon and driven by said shaft and formed with a fan-shaped opening in the walls thereof, compression blades secured in said fan-shaped opening adapted to receive the gas from the fan and compress the same into the explosion chambers, and means for providing a temporary side wall for said explosion chambers during the period of ignition.
7. A fuel compressing device forrotary gas engines comprising 1n combination with an explosion chamber and a driving rotor to receive the impulses from the charge exploded in said chambers, a rotatable compression wheel mounted adjacent to sal explosion chambers and formed with a transverse opening in the body thereof, fixed blades mounted in said opening and adapted to force and compress the charge of fuel in said explosion chambers, means carried by said compression wheel for producing a temporary side for said explosion chambers during the period of ignition, and means for supplying fuel to said compression wheel.
In testimony whereof I afiix my signature in presence of two witnesses.
