A 25 pivotally connects the engine when starting. with the slide 9 and with the crank portion 4. Still further the present invention proposes O A conventional slide 26 is slidably mounted that the piston rod urging means be a resilient in a steam chest 27 and controls the ports 28 and means for urging the Crank portion to rotate in 29 to the top and to the bottom of the cylinder 20. one direction past its dead centers, while starting Said also controls the exhaust port 30. the .
