To all whom it concern. 7

Be it known that I, BENJAMIN LOMAX HARDY, a citizen of the United States, re-

siding at Mobile, in the county of Mobile and tate of Alabama, have invented certain new and useful Improvements in' a Rotary Gasoline Motor, of which the following is a specification.

This lnvention relates to rotary gasoline motors and 1t conslsts 1n the novel features hereinafter described and claimed.

'. tons may pass.

An object of the invention is to provide a motor of the character stated which is of simple and durable structure having its parts and features so assenibled and arranged as to affect a preliminary compression of the gases or mixture and means for passing the fuel in compressed form into an explosion chamber in which a series of istons is mounted for rotation.

W ith this object in view the motor in-- cludes a shaft carrying a series of pistons and passing transversely through the explosion chamber and a compression cylinder having a piston movably mounted thereon, means being provided for operativelytake which connects with the compression chamber and means are provided uponthe shaft for opening the valve to permit the gas to enterthe compression chamber as the piston is moving upon its intake stroke. the accompanying drawings Figure 1 is a to plan view of the motor with parts thereof in section.

Figure 2 is a similar view of the motor showing the piston at the end of its intake stroke. a

Figure 3 is a side elevation of the motor with parts in section.

Figure 4 is atransverse sectional view through the explosion-chamber of the motor.

Figure 5 is a transverse sectional viewthrough the compression chamber of the motor. a A

The rotary gasoline motor mmpr ses a base 1 having a standard 2 mounted thereon and in which a shaft 3 is journaled for rotation. An explosion chamber4 is mounted upon the base 1 and a shaft 5 passes transversely through the explosion chamber. and is provided at one end with a beveled pinion 6 which meshes with a beveled pinion 7 mounted upon the shaft 3. A compression chamber 8 is mounted upon the base 1 and a gas conduit 9 communicates with one end portion thereof. A spring'pressed valve 10 is arranged to con trol the passage way through the conduit 9 and the stem of the said valve projects beyond the side of the conduit. A star wheel 11 is mounted'upon the shaft 5 and is arranged so that its peripheral surface will wipe over the stem of the valve 10 as the shaft 5 is rotated. A disk 12 is mounted upon the shaft 5 and is housed within the intermediate portion of the explosion chamber 4. A series of spaced pistons 13 are mounted upon the periphery of the disk 12 and are housed within the outer portion of the explosion chamber-4.

The explosion chamber 4 is provided with:

an exhaust port 14. 4

A piston 15 is slidably mounted in the compression chamber 8 and an abutment 16 is fixed to the inner face of the piston 15. The abutment 16 is provided at its side with er 4. The abutment 16 is further providedat one edge with a recess 18 through which the pistons 13 may pass as the disk 12 rotates.

A rod 19 is connected at one end with the piston 15 and passes through the end wall of the compression chamber 8. A

crosshead 20 -is connected with the outer a duct 17 adapted to establish, at certain end of. the rod 19' and rods 21 are pivotal- 1y connected at one end with the opposite ends of the cross head 20 and pivotally connected at their other ends" with a cross bar 22 which is pivotally and eccentrically connected with a disk 23 mounted upon the shaft 3. An suitable means (not shown) maybe provided for firing the charges of gas in the explosion chamber and such means may be in the form of usual spark ph igf.

e operationof the motor is as follows Assuming that the-shaft 5 has been started in rotation, the beveled inions 6 and 7 rotate' the disks 23 where ythe bars 21 are moved longitudinally and the rod 19 and piston 15 are reciprocated. As the piston 15 moves toward the valve 10, the gases which have been receivedwithin the compression chamber 8 are compressed and when the ducts 17 move into register with the interior of the ex losion chamber 4, the solid portion of the a utment 16 is disposed completely across the explosion chamber 4 and the said gases are then exploded in the chamber 4 whereby they expand and operate against the end of one of the pistons 13 and augment the rotary movement of the shaft 5. After the explosion takes place, the valve 16 moves from the position shown in Figure 1 of the drawing to the position shown in Figure 2, whereby one of the pistons 13 may move through the clearancespace provided at the recess 18 and the piston 15 is retracted upon 5 s intake stroke whereby the gas is drawn in through the conduit 9 into the chamber 8.

As the shaft 5 rotates the pointed end portions of. the stellaform wheel 11 engage the stem of the valve 10 whereby the said valve is moved to an open position to permit the flow of the gas from the conduit 9 into the compression chamber 8. The points of the wheel 11 are so timed with relation to the movement of the piston 15 that the valve is opened while the piston is moving upon its intake stroke and as the piston moves upon its compression stroke the point of the wheel 11 passes beyond the stem of the valve 10 whereby the said valve may close under the influence of the impelling spring and consequentl communication between the interior o the compression chamber 8 and the conduit 9 is interrupted and the gases compressed in the chamber 8 by the forward movement of the piston 15 and when the end of the duct 17 comes into register with the interior of the explosion chamber 4, the said compressed gas is expelled from the compression chamber by the action of the piston 15 into the explosion chamber.

Having thus described the invention, what I claim is a 1. A rotary motor including an explosive chamber, a shaft journaled transversely therein, pistons operatively connected with the shaft and housed within the explosive chamber, a compression chamber, a piston.

mounted for reciprocation in the compression chamber, means operatively connectin the piston with said shaft, a valve controll conduit for leading the fuel into the compression chamber, means carried by the shaft for operatin the valve, a plate atutment carried by t e last mentioned piston and adapted to move transversely across the explosion chamber and having a duct formed in one longitudinal edge adapted to transmit the gas from the compression chamber into the explosion chamber and provided with a recess through which the first mentioned pistons may pass. Y

2. A rotary motor including in combination, a base, a shaft 'ournaled transversely of the base at one en thereof, an explosion chamber mounted at the other end of the base, a shaft journaled transversely through the explosion chamber and longitudinally of the base, gearing connecting the two shafts, a compression cylinder mounted longitudinally of the base between the first mentioned shaft and the explosion chamber, pistons operatively connected with the second shaft and housed within the explosion chamber, a second piston mounted for reciprocation in the compression cylinder, means oper atively connecting the second iston with the first shaft, a valve controlled conduit for leading the fuel into the compression cylinder, means carried by the second shaft for operating the valve, a plate abutment carried by the second piston and adapted to move transversely across the explosion chamber and having a duct formed in one longitudinal edge extending from the piston and terminating at an intermediate point of the abutment and adapted to transmit the gas from the comression cylinder into the explosion chammay pass.
