LEWIS L. SCOTT, OF ST. LOUIS, MISSOURI.
STEAM ENGINE.
Application filed March 27, 1922. Serial No. 547,104.
T 0 all whom it may concern:
Be it known that 1, LEWIS L. Soon, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have invented certain new and useful Improvements in Steam Engines, of which the following is a specification;
This invention relates to a single acting steam engine particulmly for automotive use. The object of this invention is to provide means for keeping the condensed steam from passing into the crankcase of said engine. l have found that unless some means is provided to prevent water from getting into the crankcase of this type of engine that said water will get into the crankcase and will float oil the lubricating oil and will freeze up in cold weather, therefore it is very desirable to eliminate this trouble.
The invention is illustrated in the accompanying drawing which is a vertical section of a well known type of single acting steam engine. a
Referring So the drawing, the numeral 1 indicates the upper part of the crankcase of my single acting steam engine, 2 indicates -the lower half of said crankcase, 3 is a partition which separates the oil chamber 4 from the main crankcase chamber 5. The numeral 6-indicates cylinders which are attached to the crankcase 1, said cylinders being set at an included angle of 90, 7 indicates a steam inlet connection, 8 is an inlet valve, 9 is a passage from the valve 8 to the top of the cylinder 6. The intake valves 8 are opened by the cam 10 through the push rods 11 and closed by the springs 12. The
. operates in the cylinder cam 10 is driven from the crankshaft 13 by any suitable means .(not shown). 14 indicates exhaust ports, which ports connect with the exhaust passage 15. The piston 16 6 and is connected -to a common crankshaft pin 18 by means of a piston rod 17. While I have shown but two cylinders, it is obvious that any number ofcylinders may be used. Each of the cylinders 6 is ,provided at its lower end with a flange 6 by means of which it is secured to the crankcase.
The means which I employ for preventing the steam, water or other fluid from passing down the cylinder wall into the crankcase. comprises. in the preferred embodiment of the invention, a stationary sleeve 19 which is provided at its lower end with a flange 19 by means of which it is secured to the crankcase, said flange being interposed between the flange of. the cylinder and the wall of the crankcase, as shown. This sleeve projects upward into the piston and the inside of the piston 16 is machined so that the upper part of the casting 19 fits the inside of the piston 16. Any steam or water that might travel down the outside of the piston 16 will run out the drain opening 20 in preference to passing upward over the casting 19 and into the crankcase. The pistons and cylinders may be lubricated by any suitable means through the openings 21. I
While I show my arrangement for preventing the fluid which actuates the piston from passing into the crank case of a steam engine it is obvious that this same arrange ment could be applied to an explosive. type of engine for preventing unburned fuel which passed down the piston from getting into the crankcase.
I claim:-
1. In a single acting reciprocating engine. a crankcase, a cylinder attached thereto. a piston operating in said cylinder. a stationary sleeve secured to the crankcase and adapted to closely fit the inside diameter of said piston said cylinder being provided at its lower end with admin opening located extcriorly of the wall of said sleeve, the construction preventing any fluid that might pass 'down around the outside of said piston from entering the crankcase of said engine.
2. In a single acting reciprocating engine, a crankcase, a cylinder attached thereto, a piston operating in said cylinder. adrain located at the lower end of said cylinder for conducting oil any fluid that might pass down the cylinder wall, a stationary sleeve adapted to closely fit the inside diameter of said piston for'preventing said fluid from passing into the crankcase of said engine.
3. In a single acting reciprocating engine, a crankcase, acylinder having flanged lower end attached to said crankcase, a; piston opthe crankcase of said engine, said sleeve berating in said cylinder, adrain located at ing flanged at its lower end and attached to the lower end of said' cylinder for conductcrankcase.
ing ofl? any fluid that might pass down the In testimony whereof I have hereunto set 5 cylinder wall, a stationary sleeve adapted to my hand.
