SAFETY nrerrrnn roa GAS srov'ss on THE LIKE.
Application filed August 20, 1928. Serial No. 300,837.
This invention relates to devices for light! ing the burners of a gas stove, and more particularly to a pilot light which is kept burning for the purpose of lighting the gas whenever it is turned on.
It is an object of my invention toprovide a ,pilot light which is simple in structure and reliable in operation.
It is another object of my invention to provide an individual pilot light for each of the gas burners which is automatically controlled by the turning of the valve handle for each of the burners whereupon the pilot light is jetted outwardly into the burner.
The pilot light is so positioned that it will light the gas whenever it is turned on, either by accident or otherwise.
Other objects and advantages will appearfrom the detailed description whi'chfollows taken in conjunction with the accompanying drawing. i
I attain these objects andadvantages by means of the device illustrated in the drawin wherein j %igure 1 is a plan view of a gas stove with the invention applied thereto.
Figure 2 is an enlarged detailed view showing the automatic. control means between the valve for the gas burner and the valve for the pilot light, the pilot light being shown equipped with a small guard for preventing its extinguishment by water or Similar numerals refer to similar parts throughout the several views.
Referring to Figure 1, the gas stove is provided with a main supply pipe 2, the
branch supply pipes 3 and the; burners 4.
A valve cock 5 with the handle lever 6 is provided for each of said burners. The main supply pipe -2 is provided with a branch plpe 7 to which a smaller pipe 8 is lights 12.
secured by means of the T union 9. The pipe 8 is parallel to the supply pipe 2 and from it run the feed pipes 10 for each of the pilot As shown in Figure 2, each of the feed pipes 10 is provided with a valve means 13 of usual construction having a spring actuated closure 14. The supply pipe 2 is provided on its upper surface with cupped ugs 15 to which are secured springs 16. The cupped 'lugsm'ay be made integral with the supply pipe 2 or maybe attached thereto by means of a-separate band. To the 11 per end of the helical spring 16 is secure the upper portion of the lever 17. The lever 17 is substantially S-shaped and is attached to or adapted to contact with the handle 22 of the spring urged closure 14 at its extremity 23. The relation between the spring 16,
the lever 17 and the valve means 13 for the I valve cock 5 the handle lever 6 will contact the flat portion 18 of the lever 17 and will depress the lever 17 which in turn depresses the spring urged means 14 which causes the pilot light to be jetted into' the surrounding gas burner. As shown, eachof said pilot lights is centrally disposed within each of said gas burners 4. The feed pipes 12 are-each provided with a small upright pipe 20 having a tapered end with'openings therein to form tlie'pilot light. The upper extremity of the tapered end is provided with a guard 21 which resembles an inverted saucer.
As shown in Figure 2, the burner 4 is not shown with the grating which is generally used thereon and which would clear the guard 21. In any event, the pilot light should be so constructedthat the guard does not interfere with any vessels which may fication may be employed in such a case by securing the guard portion to a helical spring which in turn is secured to the pipe 20 which would allow the guard portion to yield in case it extended above the gas burner.
be placed on the burner. A further modi- The operation of the device is as follows.
The pilot light remains at alltimes lighted. When .it is necessary to light a gas burner the handle lever is turned as in the general operation of opening the same and I spring urged control means on the feed pi e j 10, to which the pilot light is attached, t e spring urged means releases more gas to the pilot light and causes the pilot light to become fuller and giving quicker ignition.
The contact between the handle lever and.
the spring urged means associated with the pilot light is made only when the handle lever contacts the lever during its path of turning in either the OH to on, or the on to off directions. vWhen the handle lever passes beyond the topmost portionfof the lever actuating the pilot light in either'direction, 'the pilot light again burns low.
The same results are obtained should the tation. I do not wish to be limited to the exact structure of the preferred embodiment shown and described, or to any particular material used in; the construction of parts, or to the design of parts, but desire protec tion as against any variations in structure or substitution of equivalents which utilize the principle of my invention and fall within the purview of my invention and are within the spirit and scope of the following claim.
The invention having been set forth, what is claimed as new and usefulis:-
A gas stovehaving in combination gas burners, branch supply pipes therefor, a main supplypipe, an individual pilot light for each gas burner, a substantially parallel feed 3 pipe for said pilot llghts, said 1n lvidual pilot lights being positioned centrally of said gas burners, a guard 'on each, of said pilot lights to protect it against liquids, said feed pipes ipeconnected to said main supply being providedwith a spring urged control means for each pilot light, control means for each pilot light, said gas burners having ranch' feed pipes on said arallel feed each an individual valve cock provided with a handle, a substantially S-shaped'means contacting said spring urged control means and passing under 7 said handle, said S-shaped means being so ositioned that it is adapted to be iepressed y the turning of said handle.
