Application r1811 September 14, 1906. serial No. 334,644.

. United States, residing at Lexington, in the county of struction, when left closedfor any considerable time,

rust fastens the same and they become inoperative;

Globe valves cannot be successfully employed since there is always more-or less dust present in producer gas, which accumulates upon the seat and is simply' compressed and fastened there by the pressure of the valve in closing. When the valve is again opened a part of this deposit adheres to the valve and a part to its seat, so that frequent opening and closing of the valve soon results in making the valve and seat uneven in their contacting surfaces, thus causing serious leakage. Since the pressures employed in producer gas work are never more than a few ounces per square inch, these valves need not be designed for heavy pressure.

The object of my invention is, therefore, to over come the foregoing objections and to accomplish the same in a simple and effective manner.

Said invention consists of certain features or instrumentalities substantially as hereinafter fully disclosed and specifically pointed out by the claims. In the accompanying drawings illustrating the preferred embodiment of my invention, Figure 1 is a sectional elevation of certain parts of a gas-producer, with said invention applied thereto, Fig. 2 is a view thereof, with the cover or closure removed, showing the valve proper in position over one port, and a second port uncovered. Fig. 3 is a general like view of the same, with the valve proper also displaced. Fig. 4 is a general similar view taken from the reverse side"o fthe responding surface of the boss or ledge 6. Between these ports and pipes 8, 9 connection may be suitably I effected, leading to the required points. Upon said i seatplate is adapted to work or slide a valve 10 for condisk-like and having its face which is trued brought to a sharp edge as at 11 around its entire circumference, whereby it is noted that, with the usual opening and closing movement of the valve or disk it will, in itself, have a scraping action upon said valve-seat and thus provide for the practical automatic cleaning of said seat and accordingly guard against the sticking of the valve from any deposits of gaseous products which would otherwise remain upon the seat.

A suitable handle or lever 12, which may, or may not be enlarged orweighted at its outer end for effective movement, is passed through the seat-plate 1 and its inner end, which end is let into, and :bears in a step or socket 14 formed in a housing or closure 15 suitably bolted or secured to said platen Said arm itself, has attached or fixed thereto and at right-angles, a second arm 16, which has its distant end sleeved upon a central outstanding stud or pin 17 of'the disk or valve 10, whereby, it is noted that, as the handle or lever 12 is suitably actuated, the valve will be swung fromone port to another in alternately covering and uncovering the same, as the requirements of the case may demand. A spring 18, preferably coiled or helical, is suitably applied to the arm 13 of the lever 12 so as to ultimately deliver its tension or pressure upon the valve or disk 10, for the retention of the latter upon its seat with sufficient force to render the contact therebetween gas or fluid tight and yet allow, by suitably manipulating the its scat in'event of such ever being required.

Suitable pipe connection as at-19 is effected between the gas-producer and'the valve casing or housing 15 for controlling the passage of the gas by the valve 10. The pipeconnection 9 may be omitted and the valve may serve equally the purposes of my invention, in that case it being styled a straight-away valve-as now shown as a three-way valve. i i

. p I claim 1. A device as described, comprising a seat-plate having opposite ports tlrerein and a continuous outstanding'ledge serving as a seat around said port's, a valveresting upon said ledge or seat and effective for closing either'of said ports, a housing arranged upon said-Seat-plate, over said ports and valve, a handled lever bearing in said housing and stepped in said seatplate, said lever having a lateral arm with a right-angled terminal sleeved upon an outstanding central stud of said valve.

trolling either of the ports 2, 3, preferably circular or has a-right-angled integral arm 13, a short distance from lever, the moving of the valve slightly outward from .mii voinnrisiny: sum-plate having onnusito i'Ui'iS llwrrin Iiilli :in outstanding; rnnrinnuns lwiu'n t'urnzinu \';|!\'v knzii around said ports, 11 valve rl'i'nriivu i'nr rIwsinu, viihrr oi sziid ports and resting upon .--:1i:i iiiili or SW1! :ii1(i Imvin :in nui'xlziniiing (:Qnirni sum. :1 housing fur vmid purix zind vzilw. ininiilrli lever passing; flll'UlrLLii Ziili housing; and Mnppvd inmiiii semi-pinto and i lnlorui :irln wiiii :i li l'ili liligiiii lvrminzil sleeved upon said Hind. iiliii :1 spring :ippiiULi in said iUVEl' interiiiWiiflhi) of it's bundle and said sentplnte for delivering prcwnro upon semi $0M, vulva and for its eileiriive retention in pusiiiion.
