`Applicatiuon filed July 29, 1919.

To all whom t muy concern.'

Be it known that I, Lnwls h/lu'rnssnn, a citizen of the United States, residing at New fflrleanain the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Valves, of which Athe following is a specification.

This invention relatesto new and useful .improvements in valves and operating mechanism therefor, and `has for an object the provision `of avalve adapted to deliver a fluid under pressure, to one or more points,

and receive from these points the exhaust fluid anddehver it to a desired point.

tfurther object 1s the provision of means l for governing the supply of fluid pressure i with `means for simultaneously cutting olf the delivery and exhaust from any of the cylinders..` i

in important object is the provision of a single valve which will control the intake and exhaust of a plurality of cylinders.

1 1 still further object is the provision of a novel cutout valve which will simultaneously close a plurality of conduits, as for example the intake and exhaust of the two ends of a piston, y

Further objects will be obvious during the course of the `following discussion.

lnwthe accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my device, through out "which like numerals designate `like parts. i

llig. 7 is a plan `view of my valve, and,

Il? 1g. 8 is a section taken through the valve easing, the plug of the valve being shown partly in elevation.

. Referring now more particularly to the drawings, the numeral 10 indicates a valve casing provided` with ports 11, 12, 13 and 111. rlhe casing is divided transversely into sul'istantially horizontal passages 15, 16, 17 and 16. Arranged vertically within these passages and interrupting the same is the plug 1 9 ofthe valve. This plug is provided with a pair of ports and 21, lying` in the same vertica plane, and `a second pair of ports 23 and 22, lying in a vertical plane at right angles to the plane of the ports 20 and 21. "The port 20 lies in the passage 15, the port 22 inthe passage 1.6, the port 23 in the passage 17, and the port 21 in the passage 18. The plug is slightly tapered and is provided on its bottoni with the usual adjusting means 24e. il bypass 25 is provided connecting the passages 16 and 16 with the port 111-.

rlhe port 11will hereinafter be referred to as the intake port, and the port 141 as the exhaust port. `Ports 12 and 13 will be referred to as the upper and the lower delivery ports, respectively.

Connected with the lower delivery port 13 is a pipe 26, with the upper delivery port 12 a pipe 27, and with the exhaust port 14 a pipe 28. A. cutout 29 is provided having ports 30, 31 and 32, the pipe 26 connecting with the port 30, the pipe 27 with the port 31, and the pipe 26 with the port 32. Ports 33,` 311 and are also provided, the port 33 communicating by a passage with the port 30, the port 34 with the port 31, and the port 35 with port 82. Arranged in the passage connecting the ports 30 and 33 is a plug 36 having` the usual aperture therein, adapted to aline with the passage when plugis in a predetermined position. Plugs 37 and 38 operating` mechanism of the `are similarly arranged in the passages conatented July 6, 1929. i

K at each impulse.

Connected with the port 33 is a pipe Li() which connects at one end of a pressure cylinder P having therein a piston 42. Gonnected with the port 84 is a pipe 11, communicating with the opposite end of the cvlinder, this cylinder being shown as that which operates a ram feeding fuel to an underfeed furnace. The port 35 communicates with a pipe leading to any desired point, this point in the present instance being indicated as the air chamber of a furnace.

lMounted above the valve 10 is a support L13, upon which is rotatably mounted a gear This gear is driven by'a worm 45 formed upon a shaft 4G, mounted in suitable journals Ai? carriedvfby the support 413, the shaft 46 being rotated in any desirable manner. The, stem 19a of the valve extends through the support i3 and is provided with a pinion 18. Suitably secured to the gear 4:4 is a segmentv i9 adapted to engage with the pinion Qand shift the same, the amount of the shifting being 90 degrees at each engagement. The support is provided with a cover 50 which incloses the gears and operating mechanism, and excludes dirt, dust and the like.

The operation of my device is as follows:

' T he plug of the valve 10 is intermittently rotated as previously described, 90 degrees lhen the plug is in the position shown in Fig. 8, the Huid under pressure enters at 11, passes through passage 15, port 20, and out at. 12 to the pipe 27, thence through port 31 of cock er cutout 29, through the passage in plug 3T, through port 34; in the pipe 4-1, and thence into the right hand end of the cylinder P, forcing the pistonV to the position shown in Jdig. 3. The plug of the valve 10 is now rotated 90 degrees, and pressure enters at 11, passes through passage 17, port 23, and out at port 13 into pipe 26, through cock or cutout 29 to the lefthand end of the cylinder. The exhaust fluids from the right hand end of the cylinder return through the saine passage by Which they are 1red from the valve 10 to the cylinder, to the valve 10, and pass through port 22, passage 1G, bypass and out of thevalvev 10, at 14, into pipe 28, thence passing through plug 38 of the cock or cutout'29, and so on to the point of delivery. rEhe valve, being again rotated,

iluid pressure again enters at 11, passes through passage 15, port 20, and out at 12 to the right hand end of the cylinder. The

exhaust fluid passes from the left hand end of the cylinder' back to the same channel by which it entered, to the valve 10, entering at 13, passing through port 21 and passage 18, to the exhaust outlet 14;;

To those familiar with the art, it will be obvious that the valve 10 may be connected With the plurality of the receivers similar to the cylinder l) and deliver fluid presA sure and receive exhaust iluids therefrom, simultaneously. By providing each of the receivers with a cock or cutout 2S it will bepossible to cut oi'lA any of these receivers, as desired.

if, for example, the valve is desired to control the fuel feed of a plurality of furnaces, the pipes 2G, 2T and 28 may be provided with branches 26', 2T', and 2S leadingr to the cylinder operating the fuel feeding rain of each furnace. A portion of the [luid pressure delivered, which in the instance cited, would Vbe steam, would be delivered through the cock or cut out 29 to the cylinders and the exhaust from these cylinders will return te the air chamber of the furnace which the am feeds. rlhe operating cylinder of each furnace will be provided with a cock or cutout 2i), similar to the arrangement shown in Fig. It will readily be seen that by cutting oili the power from the cylinder, the admission of exhaust steam to the air chainber of the furnace is discontinued simultaneously.

As many changes are possible in the sha pe, size, and arrangement of parts, I do not limit myself specifically to the structure herein shown and described, and may rcsort to any such changes without in any manner departing from the spirit of the invention or the scope of the subjoined claims.
