UNITED STATES PATENT onnrcn- WILLIAMKG.' sIMP-soN, or DETROIT, MICHIGAN.

HYDROCARBON OR GASOLENE TURBINE-MOTOR.

Application filed March 4, 1919.

To all lwhom it may concern.'

Be it known that I, WILLIAM G. SIMPSON, a citizen of the United States, residing at 1666 Brush street, in the city of Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Hydrocarbon or Gasolene Turbine-Motor,.of which the following is a specification.

This invention relates to new and useful improvements in explosive turbines and has for an object provision of a-device of this character, simple of construction and parts of which are readily replaced.

A further object is a provision of the above character wherein the entire effective energy of explosion is exerted upon the vanes of the turbine. l

Other objects andadvantages will be ob, vious during the course of the following discussion.

lIn the drawings wherein for the purpose of illustration is shown the preferred embodiment of my invention, and wherein like numerals designate like parts thereat. The figure is a transversel section through my turbine.

Referring now more particularly to the drawing, the numeral l indicates a casing having end closures 2 and 3.

A shaft 4 is mounted within the casing in suitable bearings 5 and 6. Intermediate these bearings the shaft is provided with a sleeve 7, having eccentrics 8 and 9 formed thereon.' The sleeve 7 is provided with a keyway 10 for a purpose hereinafter 'to ap-A pear. y.

Secured to the shaft 4 is a gear 11 mounted in a bearing 12 formed in the end plate 3 of the casing is a stub shaft 13. Mounted upon this stub'rshaft is a gear 14 meshing with/the gear 11 upon shaft 4. Secured to the gear 14 is a gear 15, which meshes with a gear 9 rotatably mounted upon a shaft 4. The gear 9 is provided with keys adapted to enter the keyway 10 formed in the sleeve .7.`

Formed in the casing 1 is a cylinder-16 within which is mounted a piston 17 connected `by a pitman 18 to the eccentric strap 19, which in turn receives eccentric 8. An intake chamber 20 is provided in casing 1. The communication between the intake chamber and the cylinder is closed by means of a puppet valve 21, the stem 22 of which is adapted tojbe contacted bythe eccentric 9 on vthe sleeve 7 at each revolution thereof.

Specification of Letters Patent. Patented .Blay 11 192() Serial N. 280,593.

A valve 23 governed by a dash-.pot of any suitable construction closes communication between the rcylinder 16 and chamber 25. This chamber 25 is provided with a reduced nozzle or opening directed against vanes 27, secured to, or formed'upon a fly wheel 26 secured to the shaft 4.

Secured to the gear y15 is a bevel gear 28 which meshes with a bevel pinion 2O adapted to operate a timer 30 of any suitable construction.

`The operation of my device is as follows:

The shaft 4 is rotated until the charge is drawn into the cylinder and compressed, when it will be exploded in the usual manner. The spring of the dash pot is set at a suitable point slightly higher than the point of compression in the cylinder 16, that is to say, if the point of compression in the cylinder 16 is 70 pounds the dash-pot spring is set at 75 pounds or thereabout.4

`It will readily be seen that under the force of the explosion the dash-pot valve is opened and the exhausting gas impinge against the vanes of the fly wheel rotate the same.

It will readily be seen that as long -as the pressure within the chamber remains at more than 7 5 pounds the dash pot actuated valve will remain open and exhaust continue. As soon however, as the pressure drops below this point, this valve closes and the cycle is again repeated. By supplying a suitable governor for the dash-pot, and the timer, the operation of the turbine may be governed so that the number of explosions are entirely under control of the operator. It will of course, be understood, that some suitable means for, disconnecting the timer during the period at which vthe dash-pot valve'is open mustl be supplied.

It is to be understood that the form of my invention herein shown and described is to be taken as the preferred embodiment ofl the same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

v'What I claim is,

1. In a device of the type describedfa casing, a shaft rotatably mounted within said caslng, a sleeve rotatably mounted upon said shaft, a reducing gear train connecting said shaft and said sleeve and eccentric carriedl by said sleeve, a cylinder formed in Said casinggva piston reciprocable therein, means connecting said piston and said eccentric whereby saidl piston `is reciprocated when said sleeve is rotated, means Vfor supplying a combustiblecharge to said cylinder, an exhaustavalvc for said cylinderv adapted to' be opened When the 'pressure in said cylinder exceeds the compression pressure thereof -said casing, a piston reciprocable therein, -means connectlng sald pistonl'and sald eccentric whereby said piston is reciprocated when said sleeve is rotated, means for sup'- plylng a combustible charge to said cylinder, a dash-pot controlled exhaust Valve for v said cylinder adapted to be `opened when they y pressure in said cylinder. exceeds the compression pressure thereof, and a fly Wheel secured to said shaft provided with vanes disposed in the path of said exhaust.
