GAS IGNITER.

To all whom at may concern.

Be it known that we, GEORGE M. WILLIs and ARrHUu'HUBoErToHER, citizens of the United States, residing at Chicago and Evanston, respectively, both in the county oLGook-and State of Illinois, have invented a certain new and ,useful Improvement in Gas Igniters, ofqwhich the following is a full, clear, concise, and exactdescription, reference being bad to the accompanying drawings, forming a pa'rt ofthis specification.

Our invention .relates to gas stoves and similar devices; and more specificall to an improved accessory for igniting the ame of anyburner of a gas stove without the use of matches.

In the stoves in the prior art having certain predetermined arrangements of burners, practicable to employ a fixed projector, designed to throw a fine jet of flame to each burner. There are, however, some stoves on the market in which the arrangement of the burners is such that a suitable'set of jets reaching all the burners- .can scarcely be delivered by a fixed projec tor. For such stoves a movable projector is desirable, and it isthe object of our invention to provide a movable projector device 1 for such'stoves. and, indeed, if desired, for all adaptablestoves whether or not fixed burners. are adaptable to them.

The difliculty with movable projector devices is that of leaking, particularly after it has been in service for a time, and the pro vision of such a device which will not leak,

to pass or be retained by a rotary or other moving joint and which will stand the drastic test of use under-actual service conditions is the primary object of the invention.

Further objects and advantages will become apparent as the description proceeds.

In the: accompanying drawings;

Figure 1 isa more or less diagrammatic plan view of a gas stove in which the burners areso-arranged that suitable service by a fixed projector .is .unobtainable;

Figure 2 is a much enlarged longitudinal view, principally in section, on a scale approximately twice actualsize, to facilitate in clearly illustrating the details of the invention;

Figure3 is a plan view of the structure illustrated in Figure 2;

I Application filed April 27, 1923. Serial No. 634,952.

Figures 4 and 5 are sections on line 4-4 and 5-5 respectively of Figure 2;

Figure 6 is a detailed side elevation of the actuating head; and

Figure 7 indicates a modification.

In the embodiment of the invention selected for illustration in Figures 1 to 6 inclusive, the valve casing 10 is provided with the inlet passage 12, the bore 14, the exit passage 16 and the bleed 18 for permitting sufficient flow at all times to maintain a tiny tip of flame. to cut 06' flow to the main passage and its stem 24 passes through gland 26 provided with a suitable packing 28 and carries the actuatin head 30 normally heldin the position s own by compression spring 32, which spring also operates to maintain packing 28 in proper condition. Collar 34 may be adjusted to determine the extent of opening obtained when head 30 is manually depressed. The foregoing parts as above described are old and well known in the art, being disclosed in U. S. Patent 1,227,078 to Arnold O. Rutz, May 22, 1917, and per se form no part of the present invention.

Gland 26 is held in fixed position with respect to casing 10 by reason of shoulder 36 which positions the entire gland. The projector 38. is carried at the end of arm 40, which arm underlies flange 34 to afford a mounting for its pivotal movement about the axis of the gland. The arm projects rearwardly to form a handle 42 by means of whichthe arm and projector may be swung to point at any burner desired.

Suitable flexible conduit means are provided for delivering gas from exit passage 16 to the projector 38. ,We have illustrated a rigid conduit 44 carried in blocks 46 suitably mounted on' the underside of arm 40 as by means of fastening screws 48, and a relatively short flexible connection 50 extending from the proximate end of conduit 44 to the fitting'52 by means of which it is placed in communication with passageway 16. It will be apparent that arm 40 covers and protects the conduit placed below it, and it'lnay be curved as clearly shown in Figures 4 and 5 to render it more rigid and improve its ability to protect the conduit.

Projector 38 is preferably provided with Valve 20 engages valve seat 22 provided with a flange 34 -features which may roperly be a central aperture 54 and two side apertures 56, so as to throw three slightly d1- verging jets. This results in ignition of the entire extent of the burner more quickly and certainly, and furthermore materially decreases the accuracy with which the arm must be pointed in the direction of the burner.

Referring now to Figures 2 and 6, we provide a peripheral ove 58 hav ng a central downwardly 0 set portion 60 in the lower sleeve of head 30. A set screw or pin 62 fixed in the telesco ing portion of gland 26 enters slot 58, an a small bracket arm 64 pro'ects laterally from head 30 to pass throng a slot 66 in handle When these features of construction are embodied, it will be obvious that head 30 will rotate with arm 40, and that exce it when pin 62 is in the ofl'set portion 60 t e valve will be depressed and a ct of flame for ignition urposes will be elivered from the proector. The position of the depressed portion 60 obviously coincides with the normal position of the device when not in use, and 1t is no longer necessary for the operator to depress head 30 at any time. It is only necessary to swinghthe arm 40 to point at the burner to ignite e same and complete the operation of the device. As the jet usually is a bright white flame there is no danger that it will be acoidentiy left in operation,- as the operators attention will be directed to the same until thwarts are turned back to normal osition. e also preferably provide a co spring 74 mounted on the easing and enga a pin 76 projecting from the under side 0 arm 40, to resiliently re: turn the arm to normal position.

Without further elaboration, the foregoing will so fully explain the gist of the invention, that others may, by a rent knowledge, readily adapt e sagge'for use under various conditions 0 It will for instance, be obvious that the entire valve casing might be pivoted'in'stead of merely the rojectorand its supportin means, in whic case it would be suppdite on a fixed bracket 68, see Figure 7, andconnected to the main suppl pipe 60 by flexible conduit 72. Sinn ar y pm 62; bracket arm 64, sprin 74 and the extra orifices 56 may be omitte if desired. These and many other modifications and adaptations may readily be made without eliminating certain sai to con stitute the essent1a items of novelty involved, which items are intended to be defined and secured to us by the following claims. I
