IMPROVEMENT IN STEAM ENGINES.
TO ALL WHOM Ir MAY OONOEEN;
Be it known that I, JOHN FAIRCLOUGH, of St. Joseph, in the county of Buchanan, and State of Missouri, have invented a. new and useful Improvement inSteamv Engines;. andI do hereby declare that the following is a full, clear, and exact descriptionthereof, whichV will enable those skilled Vin the art to make and use the same,
reference being had to the accompanying drawings, forming part ofj'this specification.
This invention relates vto anew and improved method of admitting steam into a steam-'engine cylinder` and exhausting it therefrom; and it consists in forming inl the piston of the cylinder the steaim-chest, and vin operating a. slide-valve with steam and exhaust-ports therein, as will be hereinafter described.
Figure 1 represents a vertical section of the piston in a. cylinder, (the cylinder. being in red,) showing theslide-valve andthe Steam passages, the section being through the line y y of fig. 2L Figure 2 is a section through the line ma: of iig. 1, showing the .face of the steam-chestwith the steam-` ports, &c.
Similar letters of reference indicate corresponding parts.
One important feature of this invention is the piston of the engine stands still while the cylinder moves,
and vthereby operates the slide-valve andimparts themotion to the machinery.
`A represontsjthe piston, which' is packed 4against the interior surface of the cylinder in the usual manner. Within the piston the slide-valve marked B is operated. C is the steam-chamber. D is the valve-rod, each -end of which extends through the piston, andis packed by smiling-boxes, as seen in the. drawing. Erepresents the piston-rod ofthe engine.` It may he said thatthere are two, piston-rods, Eiand F. Both of these rods are,
hollow, and both pass through the heads of the steam-cylinder. The Vrod E is the steam pipe andF is rthe exhaust pipe. a a represent the steam-portsin the chest C. As before stated, the piston -nnd rods E and F are fixed. The cylinder slides back and forth on the lrods at every stroke ofthe engine, and the valvcB is operated thereby. The heads of the cylinder strike the-valve-rod D, which moves the valve and admits or shuts ol` steamas tho case may be. -The cours'efof the steam is indicated by arrows. As representedin the dratving, the cylinder is exhausting steam from thcleft handl and" taking steam on the right. The part marked g represents the steam pipe from the boiler; his the exhaust-port. It will thusbe s een that all the-p`orts and the wholevalve apparatus of the engine are confined to the piston, and are consequently entirely concealed within the, cylinder, thus dispensing with all eccentrics and greatly simplifying the' construction of steam* ,engines.
Having thus described my invention, I claim as new, and desire to secure by Letters Patent- 1. The valve B, constructed as described, and vonerated by means of thc cylinder-heads through the rods D, as hereinset forth forthc purpose Specified. 7 Q Y 2. The steam-chest VC and the steam and exhaust-ports a a and z, within the piston, substantially as described. I A
3. The piston A, having thc slide-valve, steam-chest, and Asteam-ports arranged within it substantially as described, in combinationxvith a steam-cylinder, substantially as and for the purposes set forth.
