Application ledAugust 22, 1925- Serial No. 51,782.

To all 'whom it may concern.' Y

Be it known that I, JoHNELiirERSimar-V FER, a citizen of the United` States, residing at Louisville, in the county of Jefferson and I State lof Kentucky, have invented newvand useful Improvementsin Valves, of which the :following is a specification.

`This invention relates to valves especially designed to be operated from a remote point, an object being tov provide a.k valve for controlling thesupply of fuel to a burner, so that the said burner may be lightedand eX- tinguished fromV a remote point. y i The primary object lof the invention `is to provide a burner kvalve for use in connection with a water heater, so that .a heater located in the basement or4 other part of a building or dwelling, -may be. :lighted and extinguished from another part of the building orl dwelling and time and trouble otherwise required invlighting and extinguishing the burner, willbe saved. Y

Vith the above 'and' other objects in view,

the invention further `includes the following j novel features and details of construction,

to be hereinafter more fully described, illustrated in the accompanying drawings and pointed out in the appended claims.

In the drawings: i Y

Figure 8 is a fragmentary sectional View similar to' Figure 6 and showing the valve closed. y Y Figure 9 is a section showing a slightly u different form of valve. r

Q: yReferring to the drawings in detail wherein like characters of reference denote corresponding parts, the reference" character l() indicates the casing of the valve which has extending therefrom a burner lnozzle 11, no the valve being shown and described for controlling a burner. Variousv types 'of burners may be used, one of which is illustrated at B and shown as connected byan elbow E and an air valve V. It is obvious `that the valve may be used for various other purposes and it isnot the purpose of the present -application to limit the invention to the use shown and described. The valvecasing 10 includes an inlet port 12 which-may be connected to ay suitable source of gas supply and is further provided with a tubular extension 13 which carries a pilot burner P, they latter being connected to the extension by a relatively small pipe indicated at 14. At the inner end of the tubular extension 13 ythere is provided a passage 15 which communicates with the interior of the casing 10, while operating wit-hin this casing is a rotar valve member 16.V This member is provi ed with aport Yor passage 17 by means of which communication `may be established between the inlet port 12 and the burner 11, while the passage 15 provides communication between. the tubular eXtension 13, or pilot burner,` and the inlet port 12 when the valve member 16 is in closed position. A pilot light will thusP be provided so that when the valve `member 16 is'operated to open .the valve, an increased flame will be provided, while a relatively `small flame will burn when the valve member is closed. An auxiliary valve 19V is provided in the tubular extension 13 for the purpose of regulatingthe pilot. This valve member may be adjusted and held in adjusted `position by means of a lock nut20. y i

The construction covered bythe foregoing description may be varied as desired as it illustrates only one of the many uses for100 which the valve is intended.

Secured upon the reducedsquared por- -t-ion 21 of the valve member 16is what will be hereinafter termed a.l valve stem lever, the latter being indicated at 22 and shown 105 in detail in'Figure 7 of the drawings. .This lever is provided with a squared -opening 23 for receiving the squared portion 21 or stem of the valve, so that the valve member and Y lever. 22 will `berigidly associated. 'The 110 valve stem is also provided with a round or cylindrical portion 21 and a screw 24 and washer 25 serves to rotatably secure an ac tuating lever 26 upon this portion 21', so that the said actuating lever-,will be rotatably mounted. Pivotally secured to the lever 26 at 27 is one end of an actuating dog 28. This dog is located within the same plane as the lever 22 and isprovded on yone edge with atooth 29 which is adapted to engage i111 fthe .recess or n-otch 30 vprovided in one edge of the levert-22. A` spring 31' which has one. of its vendsconnected to the/lever- 26 and its opposite end connected to the dog 28 serves to yieldingly. hold the dog in contact with the lever 22. A spring 32 has one ,of its ends connected to the outer end ofthe lever 26 and its-other end connected lto the jlever 22, the purpose of the lastmentioned spring being later explained. Y Pivotally mounted upon the valvevcasing 10 as shown atl 33 is a locking `dog 34. .This dog is. located below the plane `of the lever 22 and the dog 28 and is providedwith a tooth 35 adapted to engage a lug 36 which extends laterallyfrom the valve stem lever 22 in the .path of movement of said tooth. ,One'end of the locking dog 31 has connected thereto one end-of a spring 37, the opposite endot which is connected to a pinv or stud 38 carried by the casing 10. Extending outwardly `romthe locking Adog 34 near one end thereof is a lug 39 which is located in the pathof movement of; the actuating dog 28' and is adapted to be engaged by the` edge 40 lof said dog.v This edge has extending from its inner end a lug 41 which isadapted 'to engage the inner edge ofthe lug 39v during the operation of the.V valve, as will be later explained. .The wire, rod `orA other .member 42may have one of its ends connectedl with theV outer end of the actuating lever 26 andaitsother end extended to a convenient pointwso that ay pull upon this -Wirev or rod will move thelever` pivotally. Thefvalve member 16 has'extending from its inner endy a reduced stem 43 which is surrounded` by a coiled spring-44 and when the valve is rotated in one direction, this spring will ybe `tensioned and Lwill. yieldingly resist such movement, and return the valve to its normal position when the latter is released.l Another'functionrof.the spring 44 is `to keepv the valve zmeinber 16 properly seated.

From the foregoing description and accompanyingvdrawings it Will be seen that af pull 'upon the wires-or rodf42 Will movevthe actuating l,lever pivotally so that the tooth 29 will engage the' tooth 30 of the lever 22 and will imparty rotary motion to v the lever 22 and as-.this lever isrigid with thefvalve member 16, theV latter will be r0- tated. \Duringf this movementthevlugv 36 which extends laterally from the lever 22 this lug 36 rides past the tooth 35, the said tooth will drop into position behind the lu as 'shown Vin Figure 2"of the drawings an the valve member will then be locked against reverse rotaryf movement. During this movement, the-'valveis moved from its normally'closed to an open position, the position of the valve being illustrated in Iiigurey 2of thefdravvings. .Y f i* 'When it y:is desired to close the valve, the wireor rod 42 is againfpulledto impart further rotary movement to the actuating lever 26 in the samedireCtiOn. i This causes the end 40 of the actuating Vdog 28 to engage the lug 39 of the locking dog and `as the .free end of the locking dog is held against in- -ward movement by engagement 'ofits end 50 `with the valve casing, the actuatingdog -Will be moved pivotally outwardagainst the action of its spring 31 and as the locking'dog is simultaneouslyv moved upon vits Hpivot against the action of its'spring'37, the tooth .35vvill be disengaged from the tooth 30. and the valve stein lever 22 released. a .This renders Vit possible tov turn thevalveonv from a given point vand 101iv from another point if. desired. Upon the release. of the valve stem ,lever 22, the spring 44 ofthe valve member Will-return said member to its closed position, movement inv this direction Ibeing limited by the engagement `of a tooth or extension 46 with the yst-ud 38. This reverse movement ofthe lever22, Willthrough. the spring 32,' pull the actuating lever inthe same direction until the tooth'or yextension 46 of the latter alsoA engages the stud 38.

At the` sametimefthe actuating dog'will be movedso that its tooth 29 will properly engage the wall of the notch or recessBO of the llever 22, so that the parts" will nowbe in position to again open the ,Valve when desired. f a. It willy be apparent from, an vinspection of the drawings that the-locations -of the screw 19 and pipe 14 may be varied, their positions depending' upon .the position of the valve `when installed. That is, whether the' valve is horizontallyV or vertically arranged. i
