` IMPROVEMENTIN' STEAM CUT-OPE' VALVES.

Be it known that I, WILLIAM M. STEVENSON, of Sharon, in the county of Mercer, and State of Pennsylvania, have invented certain new and useful Improvements in Non-Pressure Gut-Ol-Valves; and I do hereby declare that the'following is a full, clear, Aand exact description thereof, reference being had to the accompany-4 ing drawings, and to the letters of reference marked thereon, which form a part of this specification. v In the annexed drawings- Figure 1 represents a side elevation with'the ends of the two valve-boxes removed.
Figure 2 is a. plan view of my machine.
Figures 3 and 4 represent the two openings in the valve-seat.
Figure 5 is a plan of the top of valve-boxes, with openings for the'admission of steam.
The letters'A and B represent a, cylindrical and also a square or quadrilateral .valve-box, these being the only forms in which my invention or improvement can 'be used. C designates a boxror chest placed inside ofA .valve-box B, having a space between it and the interior of the valxe-box, for the escape of lexhausted steam, which will be discharged through a pipe, e, at the end of said valve-box B. AIn the bottom of valve-boxA B` there are'two slots g, designed to admit the steam into the cylinder. Freprescnts a shaft having on it vthe two eccentric wheels `m and s. The said shaft rests on studs attached to the cylinder. 'n represents an arm, lthe inner end of which is fastened to box C, and after passing through the side of valve-box B, is connected at its outer eind to the rod h, the said rod at its outer end being looped around the eccentric s. It will be remarked that as the shaft F revolves, the eccentric s by means of its connection with box C,Aas above described, will by regular alternation bring the opening at the bottom of C opposite to the openings g g, through which steam enters the cylinder. It will be further seen that as the steam to drive the piston is received through one of the i openings g, the said opening .will be closed as the piston returns, and the other openingg by the action of C, will beuncoverd for the purpose of letting out the exhaust steam.l It will be observed that the opening at the bottom of box C is of the same width as the slots y g, through which the steam enters the cylinder. The cylindrical valve-box A isvconstrnc'ted upon the same principle with B, except that the'hox C is made circular at'its ends in 'Order to ft, the bore of valve-box A. The end of box C is furnished with neck d, with a crank' attached to said neck. To this crank is fastened a rod t, the Aopposite end of said rod being looped over the eccentric m. On the end of shaft s is a second crank, to which the piston is attached. A By the action' of thetwo rods t and -|,ithe steam will be let in' the alternate ends of the cylinder. through the opening in the top of boxes A and B,
und the engine thus kept in motion. v
Having thus-described my invention, what I' claim, and desire to secure by Letters Patent, is-
The arrangement of the valve-boxes A and B, boxes lC C, and the eccentrics m and s, with their rods t and the whole constructed and operating as herein specied.
In testimony that I claim the foregoing as my own,I aiix my signature in presence of two witnesses. WM. M. srEvENsoN.
