To all whom it concern:

Be it known that I, WILLIAM F. Onrronn, acitizenof the United 1 States of America,

residing atDetroit, in the county of Wayne andState of Michigan, have invented certainnew and useful 'Improvements'in Gas-' pliled toflth burner;

' tro t s among th ob'ects "of the' invention an l' y combined gas con. "@Qds g ter of in the normal functions tovthe engine. b

v The invention further resides in the novel arrangement and combination, of parts, and of construction "hereinafter setforth uu',

This chamber D is pref erably formed as a part of thecombined controller andigniter E, one end of said valve 1 chamber beingpi'ovided withintegral lugs Eof the, controller screws E E7.

As shown in Fig. 2 this valveisof the needle type and is moved toward or fromthe seat F when the valve 'stem G is rotated, there being the usual threaded engagement between the valve stemand the inner Wall D of the chamber The valve stem extends through a bearlug-G carried by the insulating body E05 1 the controller and is turned by means of the operating knob, or button H.

- :The connection-between the valve stem and the operating button is arranged to cause the stem torotate with the o erating button butpermitting the. free relative, 1011- gitudinal movement of said parts. Thus, the operating button H is provided with a cylindrical housin H fixedly secured withinv the button, sai housing havin its open end partially closed by a bar This gages a flat bearin face I formed by recess ing aportion of t a stem G's Beyond the plane of the bar H the remainingportion of, the-stem G which extends within the of the operating button.

The, 1

independent longitu button is employed? for ignition control in the following manner: -An annular contact maker K is, carried by the operating button, being secured thereto by suitable means such mechanism. A plurality of contact mem-' bers L L L and L are carried by the in sulating body E and are positioned in operative relation to the contact member K. These members L L L and L extend through the insulating body E and on the opposite side thereof terminate in binding postsM M M and M respectively. 1 The;

lead from the binding postM runs t o-the lamp C and that fromthe binding post M to the lamp C, while the binding post M is CODHBCtQdtO a suitable'source of current.

Thus as shown int-he diagram; the binding post M is con nected to the lead from the magneto, and the. binding post M tothe spark plug. As it is desired to use the same contact memher for connecting the contact maker to the magnetolead in all positions of adjustment of the operating button, the binding post M is made hollow and has sleeved therein a metallic member 0 normally pressed ou't ward against the contact maker K through the medium of a spring 0 housed within .the hollow posti- "Since'the contact maker K is of anniilar form andx-extends'outward over the metallic member 0, 'it'is obvious member-O willb'eiin electrical contact in all positions of rotative and longitudinal-ad yustment of the operating member Hand will in no way interfere-*rwitlr=eithe1f ad justment.

In the arrangement of parts as above described it will be seen that a single pressing in of the operating button H will successively break the circuit to the spark plug N, close the circuitiato the lamp C and then reopen the same and finally close the circuit to the lamp C. This operation is moreover accomplished irrespective of the position of rotative adjustment of the operatingv but ton H.
