Description
p 1930. J. M. DUNGAN 1,755,474 7 GAS STOVE Filed Feb. 14-, 1927 22w fig/L INVENTOR W ATTORNEY Patented Apr. 22, 1930 UNITED STATES JESSE M. DUNGAN, or FORT :WAYNE, INDIANA as s'rovn Application filed February 14, 1927. serial no. 167,982.
This invention relates to improvements in gas stoves of that type wherein hydrocarbon fuel is utilized. The object of the improvement is to provide means for maintaining the gaseous vapor in the feed pipe for the stove in a constant state of dryness so as to be in readiness and in proper condition for combustion when admitted to the burners, and thus obviate the customary practice of priming and preliminary heating of the burners.
This object is accomplished by the construction illustrated in the accompanying drawings, in which Fig. 1 is a plan view of a gas stove equipped with the invention; and
Fig. 2 is a detail showing an elevation of a lighter in conjunction with the feed pipe through which hydrocarbon vapor is supplied to the stove.
The characters appearing in the description refer to parts shown in the drawings and designated thereon by corresponding characters.
The invent-ion is used in connection with a gas stove 1 having a series of burners 2 which are respectively supplied with a mixture of gas and air through corresponding duct-s 3,
each having a mixer 4 and valve 5, the latter being connected with a common manifold pipe 6. The construction and arrangement of the burners including their ducts, mixers, valves and the manifold pipe are such as is ordinary in the art. The invention contemplates in connection with the stove apilot lamp for igniting the gas mixture when supplied to the various burners, which igniter is of the ordinary type, and consists of a shell 7 having a series of apertures 8 and a gas burner 9 which is connected with the manifold 6 by a pipe 10, there being a valve 11 provided for controlling the supply of gas to the burner. The valve 11 is of the customary type for regulating the pilot lamp, and is normally open to such extent as to adm t the passage of sufficient gas to sustain a single jet of flame 12 from the burner 9, and may be fully opened by pressing down upon the stem 13 of said valve so that the supply of gas through the burner 9 is sufficient to cause the flame 14: to be projected through each of theopenings'S in the shell with sufficient force as to reach the corresponding burners. 2, as
in the ordinary practice. In this manner when .1 gas is turned onto any one .of theburners the gas mixture as it passes from theiburner may be ignited.
In con-ne'ction with the shell 7 is arranged a supply pipe 15, the pipe having loops 16 formed therein so that the pipe passes through the shell 7 several times in the upper part of the shell, so as to be exposed constantly to the flame 12 of the pilot lamp. The supply pipe 15 is provided with a regulating valve 17 and is connected with the manifold 6. Also, the supply pipe has connection with a pair of drums l8 and 19 with which it has communication through the customary fixtures 20 for controlling the supply of hydrocarbon vapor from the respective drums.
The invention contemplates the use of hydrocarbon in the form of easing head gasoline or naptha of such volatility as to vaporize at a pressure less than that of the atmosphere, so that gaseous vapor is supplied under constant pressure to the supply pipe from one or the other of the drums which contain the supply of liquid fuel. The vapor thus supplied is normally of insuflicient dryness as to mix readily with the air and form a completely combustible mixture. However, in the so present invention the vapor is dried by the heat derived from the pilot frame 12 as the vapor passes through the supply pipe from the drums to the manifold.
In utilizing the inventionthe pilot lamp is initially heated by applying a. torch momentarily so that the vapor in the supply pipe is dried. The dried vapor is then admitted through the valve 17 into the manifold and passes through the partially open valve 11 to the burner 9 whereupon the pilot flame is established in the shell. As the flame of the pilot lamp burns continuously the vapor in the supply pipe 15 is maintained in a constant state of dryness and in readiness to be admitted to any or all of the burners of the stove accordingly as the corresponding valves 5 are turned, the consequent mixture of gas and, air emitted from the burners being ignited by the flame 14 that is projected'from loo the pilot lamp upon manipulationof the valve stem 13.
What I claim is In apparatus of the class described, a gas 1 stove having a series of burners spaced apart; a pilot lamp; a manifold pipe having independent connections respectively with said burners and lamp; a perforated shell disposed over said lamp; a supply pipe extend H ing through said shellover said lamp and f connected to said manifold; a source supplying hydrocarbon fuel to said supply pipe un- V der pressure; and valves controlling the cor responding connections between said maniv,
fold and burners,said pipe being heated constantly by said-lamp whereby the flame of said lamp is continuously maintained during 7 operation of the burners and after all the valves for said burners are closed and the burners extinguished. y
In testimony whereof I afiix my signature.
JESSE M. DUNGAN.
