GAS STOVE.

Application led September To all /w/Lom it may concern.'

Be it known that l, HUBERT lt. .HUM- rrinnr, a citizen of the llnited States, residing at the city and county of Kalamazoo, State of lilichigan, have invented certain new and useful Improvements in Gas Stoves, oi which the following is a specification.

This invention relates to improvements in gas stoves. The main objects of this invention are:

First, to provide an improved operating means for multiple burner gas stoves in which gas may be admitted to all or a part of thc burner members as desired.

Second, to provide in a gas stove of this type an improved. igniting means.

Third, to provide an improved igniting means for gas stoves having radiating elements of foraminous earthy material.

Fourth, to provide an improved valve actuating and ignitino' means for gas stoves which is simple in structure and at the same time very eiicient.

Further objects, and objects relating to structural details, will definitely appear from the detailed description to follow.

l accomplish the objects of my invention by the devices and means described in the following specification. The invention is clearly defined and pointed out in the claims.

structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawings, forming a part of this application, in which:

Fig. l is a. front elevation of a gas stove embodying the features of my invention, parts being broken away and other parts omitted to illustrate features of the invention; other parts being shown conventionally for convenience in illustration.

Fig. Il is an enlarged detail fragmentary view of the burner and the burner valve operating means partially in section on line ing means, the burner manifold being shown partially in horizontal section.

Fig. Vl is a detail section on a line corresponding` to line 6 6 of Fig. ll, showing details of the valve actuating mechanism.

F ig. Vll is a detail section through the valve on a line corresponding to line 7 7 of Fig. lV.

Fig. Vlll is a. detail section through the valve on a. line corresponding to line 8 8 of Fig. lV.

Fig. IX is a detail vertical section on a line corresponding to line 9 9 of Fig. l, showing the arrangement of the igniter elements on the firebaclr.

Fig. X is a detail horizontal section on a line corresponding to line 10-10 of Figs. l and X.

Fig. Xl is a diagrammatic viewY showing the electrical connections for the igniter and the valve actuating means.

ln the drawings similar reference characters refer to similar parts throughout the several views, and the sectional views are 'taken looking in the direction of the littlearrows at the ends of the section lines.

Referring to the drawings, 1 represents the .frame or body of the stove, 2 the fire back which is arranged the-rein, and 3 the foraminated tubular radiating elements which are disposed in front of the iirehack.

rlhe iirebacl is preferably provided with an overhang 4 at its upper end, the upper ends of the radiating elements being adjacent to and under this overhang, as shown in lX.

The burner .is of the general character of that shown in my application for Letters Patent, filed Aug. 3. 1920, Ser. No. 400,948, and consists of a plurality of independent burner tubes or members 5 each operatively associated with one of the radiating elements The gas delivery nozzles 6 are mounted upon the manifold 7 so as to deliv r to the lower ends of these tubes. The manifold. has va chamber 8 with which a part of the nozzles dare connected and a chamber 9 vwith which the remaining tips are connected.

The casing has ports 12 connecting with the manifold chamber. The valve 1B is rotatable in the casing and is provided With a longitudinal bore or passage 14 communieating with the supply pipe. The valve has ports 15 and 16,-See Figs. IV, VH and VIH, adapted to be brought into register with the casing ports 12. The port 16 is elongated so that while both ports are simultaneously opened the port 15 is cut o therewith;

prior tothe closing of the port 16. This delivers gas to all of the burner members when the valve is actuated to open the same. The second actuation cuts olf a part of the burner members and a third actuation cuts off all of the burner members.

4In the structure illustrated this is accomplished by 'means of an electromechanical mechanism consisting of an electromagnet 17, the armature 18 of which is connected to the pawl carrier 19 by means of the link 20. A vcoiled spring 21 returns the armature when the current is cut ofi".

The pawl carrier 19 is rotatably mounted on the stein 22 carrying a Sleeve 23 rotatable On this slecveis a ratchet wheel 24 and a stop wheel 25.

in* engagement with the ratchet wheel by the spring 27,-see Fig. VI.

The link 2() has an extension 28 coacting with the stop `ratchet 25 preventing overthrowr of the valve. The valve stem is also provided with a hand wheel 29 so that the valve may be manually manipulated if desired,-see.Fig. IV.

Vith this arrangement, on each actuation of the electromagnet the valve is ad- 'the burner members.

I arrange an igniter, designated generally by the numeral 30, in a recess 31 in the fireback adjacent the upper ends of the radiating elements and below the overhang l of the ireback. This igniter, in the structure illustrated, is a resistance wire wound upon v a suitable core. The igniter is connected by the Wires 32 in series with the electromagnet, as shown diagrammatically in Fig. XI, the circuit 33 being controlled by a switch 34 automatically opened by the spring 35 so that when the switch 34 is held closed by the operator the armature is actuated and current is supplied to the igniter,y the current beingsupplied as long as the switch is held open, it being automatically cut off upon releasingthe switch. This enables the operator'to maintain the current on the igniter until the same is heated suliiciently to light theses, f i

By positioning the igniter as I havev described, the .gas 'is'turn'ed on land flows up The pawlv 261is of- -v lthe reciprocating type -being held yieldingly through the radiating elements below the ireback and a suitable igniting mixture is secured so that the burners are lighted without producing an objectionable explosion such as is likely tov occur where an attempt .is made to light the burners instantly upon turning on the gas or at the burner tips, the slight lapse of time required for the igniter to become incandescent being suficient for the gas to reach the top oi' theradiating elements and to form a proper lighting mixture.

. I have illustrated and described my -improvements in an embodiment which I find highly satisfactory. I have not attempted to illustrate or .describe certain modifications and adaptations whichI contemplate as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as maybe desired. Y j

Having thus described .my invention, what I claim as new and desire to` secure by Letters llPatent, is:

1. In a Structure of the class described, the'combination of a ireback, radiating elements disposed at the front thereof, a burner operatively'associated with said radiating elements, a gasy supply valve, an electrically controlled actuating means for said valve, and an igniter element disposed on said iirebacl andconnected to said valve control means so that current is supplied to the igniter element upon the actuation of the valve.

2. In a structure of rthe* classl described, the combination of a irebacl, radiating elements disposed at the front thereof, and an igniter disposed in a recess in said fireback adjacent the upper ends of said radiating elements.

3. Ina structure of the class described, the combination of a ktireback having au overhang. at the top, a plurality oftubular foraminated radiating elements disposed against the face of said reback with their upper ends adjacent :said overhang, and' an igniter disposed on said fireback below said overhang and adjacent the upper ends of said radiating elements. y

In witness whereof,I have hereunto set my hand and seal in the presence ot two witnesses.
