Referring more particularly to the drawings a cast metal body or casing I is centrally bored or cored, as at 3, to provide a cone shaped bearing surface 2 for a plug valve 4. An integral, cylin drical and screw threaded extension 5, at one end of the casing I, and axially aligned with respect to the cone shaped seat or bearing sur face of chamber or bore 3, communicates with the latter through an axial outlet passage i, leading to the burner not shown.
This outlet passage G is provided at its outer extremity with a needle point or valve l, cooperating With an adjustable perforated cap 8 to restrict the flow of gas to the desired maximum for supporting a full flame at the burner, when the plug valve is in full on position Casing I also includes a hollow laterally projecting extension or branch 9, externally threaded at its outer 20 end for convenient attachment to a manifold, not shown, and provided with a main supply passage I0 communicating with the bore 2. The supply passage Ill also communicates through an angularly disposed Icy-pass passage II, with a chamber or pocket I2, within an internally and externally threaded extension I3, integrally formed with casing I and angularly related with respect to lateral extension or branch 9, and this pocket communicates with the bore 3 through a second by-pass passage I4, located in the plane of main gas supply passage IU. A set screw or valve member I5, controls the volume of gas flowing through the Icy-pass passages to the casing into bore 2 when the plug valve is in simmer or low flame position. A cap IB threadedly engaged with the outer wall of extension I3 prevents escape of gas, and when unscrewed permits adjustment of valve I5 in pocket i2. The area'of by-pass passages II and I4 are suicient to support maximum low flame burner requirements, finer adjustments being made with valvemember I5.
The plug valve 4 is bored at its inner end to provide a longitudinal passage II, and is formed with a short lateral intake passage I8, communieating with passage I1, which may alternately be brought into alinement with main gas supply passage I0 and by-pass passage I4, so that a full flow of gas from passage I0 may flow direct into the longitudinal passage I1 and thence to axial outlet passage 6, or a reduced supply through by-pass passages II and I4 in the casing to and through lateral passage I8 in the plug and thence down through longitudinal passage I'I to 55 axial outlet passage 6, according to the position to which the valve 4 has beenrotated.
The valve thus described is a simmer valve having a fully opened position, a simmer position inwhich the quantity of gas passing through the into and interengaging with a hollow reduced eX- u tension 20, integrally formed on the outer end of the valve. Thus the stem is provided withy afk stud or pin 2l which extends into a longitudinal slot 22 formed in reduced portion or extension 2), for slidably but non-rotatably interengaging the stem with the plug valve, when said stem is partly forced into the extension 20, againsty the tension of a coil spring 23. The inner encl of this spring seats within the bore 2-3 of slotted exten sion 23, the other end being received within the circular recess 25- in the hollow inner end of the Valve stem, and bearing against alocking member orplate'Z-G. This plate has adisk shaped body portion 2l, which tssnugly but slidably within the recess 25, in the stem I9, and is formed with a finger 23 adapted toproject outwardly through a side opening 30 in the lower hollow end of the stem and into and throughtheV slot 22- for engagement with the inner face or edge of a locking ring or sleeve 23, in turn loosely sleeved over the reduced end or extension-2lo1-y thevalve plug. Assembly of the locking plate 26 can be readily effected by inserting the disk shaped body portion 2l thereof into the circular recess 25 of valve stem I3 at an angle and theny projecting the finger 28 outwardly through the circular opening 30 formed in the side of the stem, the diameter of the latter being considerably smaller than that of the body portion 2l, but suciently large to permit of the necessary relative sliding or rocking movement between the plate and the stem.
Ink order to lock the lower end of valve stem I9 and the coil spring 23, within the opening or bore 213 and also lock the ring 29 upon the plug Valve, the upper end of extension 20 is formed with two small openings 3|, at one side of and adjacent the slot 22. These openings are adapted to receive the bent ends 320i a wire ring 33, itting in groove 20', which is thus xed to the extension 20 in the path of movement of the ring and prevents the same from slipping off the upper end of the plug, whenever it becomes necessary to remove the latter from the casing for the purpose of greasing the plug, as is frequently the case.
The outer end of casing l is formed with an externally threaded flange 34, provided in opposite sides thereof with notches 35 and 36 of different sizes. The locking ring 29, which is of the proper external diameter to t snugly within the flange 34, is formed with lugs 37 and 33 of different sizes, corresponding in width with the notches 35 and 36 in which the lugs are adapted to seat. The locking ring is thus held in the casing against rotation and due to the relative sizes of the slots and lugs can only have one position relative to the casing and its inlet and outlet openings. When the parts have been assembled a cap IM is screwed on the casing to hold the valve assembly in place.
The locking ring or sleeve 29 is formed with a depending flange 39 against which the finger 23 of locking plate 20 is forced by coil spring 22 and over which the finger slides when the valve plug is rotated. Flange 39 has an extended portion 40 forming stops 4I and 42 for finger 28 and is provided with a notch 43, intermediate these stop shoulders and against which and intov which the nger 28 is adapted to respectively engage and snap during. respective positions of the sages I I and III are closed to communication withA the longitudinal outlet passage Il' in the plug. Upon anti-clockwise rotation of the pluguntil linger 28 snaps into notch 43, in flange 39, of
' locking sleeve or ring 29, direct communication between the main gas supply passage ill and plug passage Il will remain closed but a reduced supply of gasf'is then free to ow through the angularly disposed by-pass II to pocket I2 and thence through straight by-pass passage I4 to the inlet. I 8 for longitudinal passage l1, this' flow of gas; being sufcient to provide the desired simmer flame (see Figure 4). In order to rotate the valve still further in an anti-clockwise direction, to its full open or main burner position, (see Figure 5), it is necessary to press the stem inwardly against the tensionof coil spring 23, until finger -28 is forced out of notch 133, whereupon the valve may be. rotatedy until finger 23 contacts and is stopped by shoulder 42. A full supply of gas will now ow direct from main gas'supply passage I0 into and through plug passage Il to the burner. The nut or cap dll adapted for threaded connection with the flange 3d prevents nger or stud 2 I from jumping out of the slot 22. and otherwise locks the partsin their operative relation. When in this position, and at all times, the spring 23 is forcing the valve stem and locking plate 2S LII) LTU
upwardly and causing a frictional engagement y of the nger 28 of the latter with the depending flange 39 of locking sleeve 29, thus preventing the easy turning of the plug. At the same time the spring is exerting a downward pressure vonl the plug to hold it tightly to its tapered seat.
In assembling the stem and valve plug the spring 23 is first inserted in the plug and after the locking. plate 26v has been placed in the stem, in the manner previously described, the stem is inserted in the `bore 22 of slottedv extension 2U, withv the locking plate or ring 2G resting on top of the spring with its finger 28 in slot 22. As the stem is pushedl home in the bore 2li, the stud or pin 2I and finger 28 travel downwardly in the slot 22. Locking sleeve 29 is then sleeved over extension 23 of the plug valve and nally the bent ends of locking ring 33, seated in peripheral groove 2-0, are secured. in the openings 3l. The locking plate 26 is prevented from displacement by the sleeve 29 and both of these parts are securely held on the plug 'by the wire locking ring.
Having thus described the invention, what I claim is: v
A valve comprising a casing., a hollow plug valve rotatable in said casing,a valve stern slidably but non-rotatably mounted in said valve and formed with a circular recess in its end and with a lateral opening communicating with said recess, a valve latching sleeve sleeved on said plug, and means for preventing relative rotation of said sleeve and casing, a latching member loosely carried by said stem having a body portion snugly received in the circular recess of said stem and formed with a nger portion projecting through said lateral opening and cooperating with said sleeve to stop the rotation of the valve when the valve is turned ROBERT E.
