VALVE.

Application filed December 14, 1921. Serial No. 522,426.

To all whom it may concern:

Be it known that 1, CHARLES F. MAT- TINGLY, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvement in Valves, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to certain improvements in valves and has relation more particularly to a device of this general character especially designed and adapted for use in connection with a water gage, and it is an object of the invention to provide a novel and improved device of this general character which can only be operated in two positions, namely, either wide open or closed.

Another object of the invention is to provide a novel and improved device of this general character which cannot be adjusted in a manner which will create a false registration of the water within a gage glass.

It is also an object of the invention to provide a novel and improved device of this general character wherein the valve is maintained open under proper pressure at opposite sides thereof, together with means whereby the valve is automatically caused to close upon reduction of such pressure at one side of the valve.

The invention consists in the details of construction and in'the combination and arrangement of the several parts of my improved valve whereby certain important ad vantages are attained and the device rendered simpler, less expensive and otherwise more convenient and'advantag'eous for use,

as will be hereinafter more fully set'forthr The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein: -f wFigure 1 is a View partly'in section and partly in elevation illustrating a valveconstructed in accordance with an embodiment of my invention; and

Figure 2 is a view partly in section and partly in elevation of the structure as here in disclosed, said view being at a quarter turn relative to- Figure 1.

As herein disclosed, my improved valve com rises a casing 0 having its outer end insertible through'the casing C.

closed by a removable plug 1 which, when removed, facilitates the proper mountin of the gage glass G, said glass being readily Engaged with the inner portion of the casing U is a sleeve or nut 2 which serves to maintain the glass G in working position.

The casing C has a portion 3 outwardly offset and extending laterally from said off set portion 3 and in communication with the chamberX afforded thereby is a tubular extension 4 provided with an internal valve seat 5 adjacent its inner end and havingits outer end closed by the removable plug 6. In communication with the bore of the extension 4 and extending laterally therefrom and in a general direction toward the casing C is a nipple 7 adapted for communication with a boiler and preferably through a connection aifordedby an adapter 8. The wall of the extension 4 remote from the nipple '7 and at a point alined with the bore thereof is provided with an opening 9 normally closed by a removable plug 10, said plug 10 being easily removed to facilitate the cleansing of the interior of the casing G and the extension 4.

Communicating with the interior of the chamber X and in threaded engagement with aside wall of the offset portion 3 of the casing C is a bushing 11, the inner portion of the bore of said bushing being formed to provide a valve seat 12. Slidably disposed through the bushing 11 is a stem 14 provided at its inserted end portion with a valve 15 for coaction with the valve seat 12. The stem 14 is of a diameter less than the diameter of the bore of the bushing 11 so that, when the valve 1 5v is in open pos1- *tion, steam and water may flow outwardly through said sleeve. The stem 14 is of such a length to extend at all times outwardly beyond the exterior end of the bushing 11 with said outer end lower end portion of the lever 18 is pivotallyengaged with said arm 20 through the instrumentality of the pin 21.

The lever 18 provides means whereby the valve 12 may be manually moved into either opened or closed position. .The lever also serves to indicatethe position or the valve 15 as said lever 18 is inclined in ,a;

link=2 This connectionbetweenthe extension 14"and-the'leve r or link 24: maybe readily.disengaged when the bushing 11 -is removed foranypurpo'se," such as the grindwin i of the valve 15 on itsseat.

he central portion of the lever or link 24 is loosely mounted upon a pin 25'supported by and bridging-the space between the outer. wall of the offsetp'o-rtion land a bar-extending transversely across the inner or open end of the chamber X and integrally formed or otherwise supported by the side walls of" said chamber; a v I I The mainvalveM hereinbefore referred to is positioned wlthin theextension 4 andc0- acts with the valve seat 5 therein. The valve M is mounted upon a stem 26 which extends inwardly of the chamber X and is provided with a head 27 pivotally con nected, as at 28, with the lower end portion of the lever or link 24.

-In practice, it is to be understood that -the valve mechanism hereinbefore described is in communication with the boiler above the water line andis a duplicate ofthecasing of a second mechanismin communication'with the boiler below the water line.

In operation, it is to be understood that when the lever 18 of each of the valve mechanisms isin a position inclined toward the adjacent casing, the associated mainvalveMis closed and the coacti n'g valve 15 opened; By pulling outwardly-upon each of the levers 18, the positions of the valves M and 15arereversed, thus effecting the desired communicationbetween the boiler and the glass G. Tl he connection afforded be tween the-valves M and 15 through the instrumentality of the lever'or link 24 causes thev'alvesM and 15 to move in unison but said valves M or 15 is opened, the other'is closed. When the desired communlcatlon'is effected with the boiler," the pressure is equalized at opposite' sides of each of the valves M and the resultant pressure within the la G and ee ce F3 e'e sirra v closed position; in reverse dlreotions'soi-that, when one' of ticularly the chambers X, will operate to instantly and automatically forcethe valve 15 into closed position whereby it is assured that the'valves M will be held in wide open position.- 7 1 7 l a v 1 Should it be desired to. closethe valves M, it is only necessary to move each of the levers 18 inwardly toward the casing C, such movement resulting in a valve M being i moved into desired contact with its seat 5 and closing communication between the glass G and boiler and at the same time -moving a valve 15 off its seat which allows the steam andwater' which is trapped within the glass G-to be released through the bor'e of a bushing 11.

' Should the glass Gbecome broken l whil the valves M are open, the pressure "which is actingfagain'st the-valves 15 will be quickly release'd'through such brokenglass'and the pressure which then rushes from the boiler" will force the valves M to their seats, thereby stopping the flow from within the boiler. Fro'rn the foregoing description it is thought to beolovio us that a valve constructed in accordance with my invention'is partieularly'fwell' adapted for use by reason of thec'onvenience and facility with which it may be assembled and operated, and'it will-alsobeobvious that'my invention is susceptibleof 'some'ch'ange and modification "without departing from the principles and spirit there'ofjand'fo'r this'reason'l do not wish tobeunderstood as limiting myself to the precise arrangement and "formation of the several'parts herein shown incarrying out my invention in 1naftercla1me'dJ practice except as here I claim: V
