To' all whom it may concern Be it known that we, Josemi WV. LUNDAHL, . nvcitizen of the United States, and OSCAR Anvin EKs'rnoM, n subject ofthe King of' Sweden, andl residents,- "respectively, of' Thornnston, in the county of Litchfield and State 'of Connecticut, and Litchfield, Flute' ville, in the county of Litchfield and State of. Connecticut, have invented a new and: Improved Automatic Ignition System for" GasLights, of which the following is a full, f "5.111 thencoo .illustrate-'one em odiment of^theimventio;, v clear, and exact description. . ,This invention relates to ignition and gals' controlled systems especially adapted "foruse in connect-ion with automobile lamps,A whereby the driver can light the lamps bya l single controller Without moving from the sent, and while the system is useful inthis `eonnectionit isto be understood that itfis applicable for house and other lighting systemsw'here the burners areftobe lighted. from; a remote point, 1 The .invention Ihas for its general object to improve and simplify the construction' and operation of combined gas controlling" and i nitinor devices so as to be reliable and. efficient in use, comparatively*inexpensive to manufacture and install and composed of comparatively few parts. Another object of the invention is the prou vision of the make-and-brenk device which operates simultaneously with the gas valve for opening and closing the primary circuit in rapid succession, so as to produce a high tensioncurrentin the secondary circuit for generating igniting sparks at the gas burner or burners, said makemnd-'break device thereby dispensing with th-e usual vibrator nt the induction coil. Another object of the invention is to so' mount the make-and-break device that the same will be actuated by the handle that op crates the needle valve, the make-and-break device including a toothed Contact Wheel and a spring Contact cooperating with the teeth, whereby the movement of the teeth past the spring contact will produce a succession of current impulses through the primary circuit. An additional object of the invention is the provision of a novel ignition device in-y cluding electrodes which are movably mounted with respect to each other so that Specification of Letters Patent.v Appmatign med september 6, 1913. serial No, 788,405. - 8 and the electrodes of the' ignition.

With this arrangement it is seen thatacontroller such as thefhandle 46 serves to open and close the supply of gas. and of the apparatus shown will be readilyv understood by those-skilled in the art to which the invention appertains, and while we have described the apparatus which we now consider vto be the? best embodiment. thereof, we desire to have itunderstood that the apparatus vshown is merely illustrative, andthat such changes may be made when desired as are within the scope of t-he appended claims.
