FUEL VIIXER FOR EXPLOSION MOTORS.

Application filed April 22, 1920. Serial No. 375,794.

To all whom it may concern: 1 designates an engine of appropriate con Be it known that I, WILLIs J. BERNETT, a struction provided with an intake manifold citizen of the United States, residing at 2 and an exhaust manifold 3. Secured to the 60 Kansas City, in the county of Jackson and manifold 3 is a vaporizer tank or chamber 5 State of Missouri, have invented certain 4,about having a curved inner wall 5 to fit closely the wall 6 of the manifold 3. The new and useful Improvements in Fuel Mix wall 6 of the manifold 3 is provided with a .

The vaporizing tank or ence being had to the accompanying draw chamber 4 is supplied from a supply tank 8 , ings, and to the letters and figures of refer of appropriate construction through the me ence marked thereon, which form a part of dium of a pipe 9, which communicates with 70 15 this specification. one end of the tank or chamber 4. Within This invention relates to an air and gas or the pipe 9 is a check valve 10, opening in the vapor mixer whereby liquid fuel is adapted direction of the tank 4 and the pipe 9 is also to be vaporized or gasified and then mixed provided with a mechanically actuated valve with air, preparatory to being introduced 11, having a valve lever 12, at one end of 75 20 into the combustion cylinder of an explosion which is a slot 13 engaged by a pin or lug 14 motor as the fuel charge. on the pull rod-15, which operates certain According to my invention the fuel oil valves for determining, the proportions of may be first gasified or vaporized and then ture.
