or sr. LoUIs, MISSOURI, A CORPORATION or-NEw JERSEY GAS COCK FOR RANGES Original application filed Jflovember 13, 1928, Serial No. 319,108. Divided and this application filed October 30, 1929. Serial No. 403,544.

" This invention relates to improvements in gas cocks for ranges and it is especially constructed to be usedin connection with what has become known in the art as ranges having concealed manifolds.

For a great many yearsgasranges have been manufactured in which the gas inani fold is located outside of the burner frame of the range. This improvement is a particular construction of a gas cock that adapts it for use when located within the burner range housing and having the handle of the cock located outside of the range housing for operation.

The construction here shown was originally filed in application Serial No. 319,108 of the present applicant for improvements in burners and cocks therefor, said application having been filed November .13, 1928 and this application is a division of the above mentioned application.

The improvement made the subject matter of this application pertains to the provision of a combined cap and nipple that closes the outlet of the housing, the cap and nipple being in a line with the .valve and its handle for operation, and it also pertains to a special construction of the valve whereby it contains a spring which is located between the valve and the said nipple for normally holding the valve gas tight in its tapered seat.

Other features of the invention will be understood from the following description.

parts being Referring now to the drawings in which A mdicates the burner top of a range, the

front portion of the burner top being closed by a front panel C which panel serves to form a memberfor concealing the manifold G which is embraced within the burner top A, and within the concealing plate C. The gas cook housing F is also enclosed within the burner top construction and at E in any desired form of burner with which the gas conveying tube H communicates.

Having thus designated in general terms Which may be of; any desired construction so far asthe presentimprovement' is concerned,

In the present construction the induction tube H of the burner E is quite, short and means are provided for elongating the passage of the gas and airrbeforeit reaches the burner openlngs and one of these means is described in the application of which this is a division. 1

The valve construction here shown has its housing F comprising a central portion 22 in which is mounted for oscillation the valve The outer end of the valve housing is provided with a projection 31-and the inner face of the handlehub is provided with projections 32, the said projections cooperating nipple.

arrangement of this spring between the inner to limit the rotary movement of the valve and thereby of the gas cock.

Attention is directed to the special construction of this valve in that the valve plug 23 thereof has a centrally arranged longitudinally extending chamber 33 whichcommunicates with the inlet nipple 24- ot the valve housing through a laterally extending opening 34 formed in the said valve plug. It will be noted that the outer end of this chamber 351is closed and that the inner end of the valve plug has an enlarged chamber 36 which receives a spiral spring 37 mounted within the said chamber. The inner end of the valve housing 22 is externally screw threaded as at 39 and adapted to receive the internally screw threaded flange-16 of the nipple 38. This nipple is externally screw threaded as at 51 and is adapted to receive an internally screw threaded. member 50 to serve as means for adjusting the fiow of gas through the said This special construction however has nothing to do with the present invention as it may be varied Without affecting the present improvement.

It will be observed that the enlarged chamber 36 that receives the spring 37 is made larger than the opening 49 formed in the h nipple 38 so thatthe coil spring 37 has its inner end resting against the outer end of the nipple and has its outer end resting against the inner end of the said chamber 36.

Attention is particularly called to the fact that the valve plug 23 has its handle and outer end smaller than its inner end and that the housing 22 is correspondingly constructed to receive the-said valve plug. Therefore the end of the valve and the outer end of the nipple serves to cause the valve plug to be seatedin its housing. a

In Figure 3u's shown that the wall of the spring receiving chamber 36 is provided with longitudinal grooves 55 and is therefore adapted to receive a tool suitably constructed for rotating the same. This rotation of the valve plug is necessary in grinding the valve plug in position in its housing 22 thus makin a ground joint between the two members and thus establishing a gas tight'seating of the plug in the housing.

Attention is also called to the fact that the valve plug is very much shorter than the ordinary gas valve plug and that the taper thereof is much more abrupt. This construction however while it i very advantageous in the construction of the valve, forms no part of the present invention except that it afi'ords room for the spring 37 and thus enables the spring to eiiiciently hold the valveto its seat.

I wish it understood that the particular construction described herein may be varied without departing from the invention described so long as the variations come within a fair interpretation of theappended claims.

mergers closing the outlet end of the housing and means to oscillate said closing the valve.

2. A gas valve of the oscillating-type comprising a housing having a tapered opening plug for opening and therein, a tapered valve plug in said opening, a gas inlet at the side of the housing adapted for communication with a longitudinal, opening in the plug, one end of the longitudinal opening of the plug being closed and the other end of the opening communieating with a combined cap and nipple, a I

"coil spring mounted in the plug and engaging the cap for exerting an outward pressure upon the plug for keeping it tight in the tapered housing opening, and means to oscillate said plug for opening and closing the valve.

3. An improved gas valve comprising a housing having therein a tapered opening, a tapered valve plug mounted for oscillation in said opening, one end of the housing opening being closed by the plug and the other end of the opening being closed by a combined jet and cap, and a gas inlet opening at the side of the housing, the plug being provided with a longitudinal passageway communicating at one end with the nipple, a port in the side of the plug adapted for communication with the inlet opening of the valve housing, a coil spring mounted within the longitudinal passageway of the plug. and engaging the cap, said spring exerting a pressure to hold the plug tightly within the tapered opening of the housing, and means to oscillate said plug for opening and closing communication between the longitudinal passageway of the plug andthe inlet openin of the housing.
