FLASH-IGNITER BURNER.

Specification of Letters Patent.

Patented Nov. 26, 1918.

Application filed October 24, 1917. Serial No. 198,295.

To all whom it may concern:

Be it known that I, FRANK A. GAUGER, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Improvements in Flash-Igniter Burners; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to certain new and useful improvements in lighting devices for gas rings or burners, preferably such as are used in gas ranges, and has for its primary object to provide a simple, economical and eflicient control valve for the igniter having a gas tight universal joint provided between its valve stem and casing whereby to dispense with the usual faulty unreliable packing generally used to prevent the escape of gas from the valve.

A further object is to provide a simply constructed flash igniter burner adapted for use in connection with a group of main gas rings or burners spaced substantially an equal distance from a common center, and adapted to be located nearer to the foremost of the main burners and having its jet openings directed toward the furthermost main burners of greater volume than the others in order to procure a flame of sufficient length to reach the same, whereby individual jet flames are played against all of the main burners for igniting those of the group which have been previously. opened to a source of gas supply, this construction permitting the disposition of the igniter burner toward the front of the range and out of the way.

With the above and other objects in view which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and particularly defined by the appended claims.

In the accompanying drawings I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, in which Figure l is an elevation of an igniter embodying the features of my invention, with parts broken away and parts in section to more clearly illustrate details of construction.

Fig. 2 is a top plan view of m device illustrating its position with relation to a series of gas burners of a range.

Fig. 3 is a sectional view through the flash igniter burner taken on the line 3-3 of Fig. 1.

Fig. 3 is an enlarged view of the flash igniter burner as depicted in Fig. 3.

Fig. 1 is a longitudinal sectional view taken through my novel control valve.

Fig. 5 is a transverse sectional view through the valve and taken on line 55 of Fig. 4, and

Fig. 6 is a. sectional view taken on the line 66 of Fig. 5.

Referring by characters to the drawings, 1 represents a valve casing having extending longitudinally therethrough the passage 2 which is reduced in diameter where it passes through the male end 3 of the valve casing which is adapted for connection with a suitable gas supply 3, the other end of said passage being internally threaded for reception of the threaded end of a flash igniter supply pipe at.

Mounted in the passage 2 and juxtaposed the reduced end thereof is a sleeve member 5 forming a valve seat which is engageable by the tapered end 6 of a plug or plunger '7 forming a valve head, which has its end opposite its tapered end 6 reduced to provide a consequent shoulder for abutment with an expansile spring 8 for normally urging the end 6 to engage with the spring 5. A centrally apertured collar 9 is provided for engaging the outer end of the spring 8 and adjusting the tension thereof.

The top portion of the casing l is recessed and threaded as at 10 for the reception of a vbonnet 11 and has its recessed portion 12 in register with an aperture 13 leading to the passage 2, the aperture 13 being of a diameter less than that of the recess 12. Leading from the top of the bonnet 11 is an opening 14% of less diameter than the recess 12 whereby to provide a curved shoulder 15 for engagement with the curved portion of an enlargement or head 16 formed 011 the valve stemv 17, an expansile spring 18 being provided for urging the enlargement against the shoulder 15 whereby to provide a gas tight universal joint, to thus dispense with the usual faulty packing which is generally required.

The inner end of the valve stem 17 projects' intothe passage 2 and is received in a socket or aperture 19 in the plug or plunger 7 and the outer end thereof projects outwardly of the bonnet 11 and has detachably secured thereto an operating handle 20. As will be apparent, when the handle 20 is rocked or moved in the direction of the arrow in Fig. 4, the spring 8 is overcome and the plunger 7 is moved from seating engagement with the sleeve 5 to permit the passage theret-hrough of gas as will be obvious, the enlargement 16 always retaining a tight joint with the shoulder 15 to prevent the escapeage through the bonnet of gas regardless of the angle of the valve stem.

In order to provide for a minimum but constant flow of gas through'the pipe 4: regardless of the position of plunger 7 a tapered vent or opening 21 is provided in the sleeve 5 which is regulated by' means of an adjusting;- screw 22 having its inner end tapered as clearly disclosed in Figs. 5 and 6, and when it is desired to close this vent entirely, the screw 22 is screwed inwardly until its tapered end engages and closes vent 21.

I Proceeding 'now to the flash igniter which I employ with the valve structure just described, 23 represents a flash igniter burner having its under portion recessed as at 24!; and threaded for engagement with the upturned end 25 of supply pipe 4:, and has its upper end 26 reduced and provided in its peripheral wallwith a series of jet openings 27 and 28 whichjcommunicate with a passage 26 leading from the recess 24, the jet openings 28 being of greater diameter than the jet openings 27 for the purposes later described. The flash igniter burner is inclosed in a cylindrical dome or hood 29 which has its wall flattened as at 30 and provided with a bulged portion 31 to'which the burner head 23 is secu'redby suitable fastenings 32, and disposed around the wall of said hood and in register with the jet openings 27 and 28 are apertures 33 and near the top of said hood are a series of vents or apertures 34 for providing air circulation therethroughv to prevent the accumulation of carbon in the hood.

As depicted in Fig. 2, the flash igniter just described is located intermediate theforemost pair of gas rings or burners 35 which are opposite the I smaller jet openings 27, leavingthelarger j'et openings 28to register with the other of saidburners 35. The flash igniter burner 23 is always alight being supplied bythe gas furnished through the vent 21 of sleeve 5 of the'val-ve, and when the valve isop'enedallthe way flame jets will project throughout the jet openings 27 and 28 andplay upon-their corresponding gas burners 35 ignitingthose of said burners which have been previously opened to a source of gas supply as will be obvious. To protect the pilot light from the cross currents of air that are produced incidental to the operation of gas stoves, the apertures 33 are out of dian'ietric alinement to prevent the occurrence of a direct draft through the hood member.

From the foregoing description taken in connection with the accompanying drawings it will be readily apparent that the gas burners 35 can be ignited Whenever their corresponding valves-are open by the use of the auxiliary gas flames directed onto said burners by the multiple or flash igniter burner 23 so that the user of the gas range is not liable to burn the hand when lighting the gas range in the ordinary manner, avoiding the dangerous use of matches and waste of gas.

I claim:

1. The combination with a firing member, of a control valve therefor comprising a casing having a passage extending therethrough, a plunger in said passage and normally closing the same, a bonnet portion on the casing and having an opening therethrough to said passage, and an operating stem having a universal joint in said bonnet and engaging said plunger to open and close the passage.
