Be it known that I, LEOPOLD .F. BURGER, a
l citizen of the- United States, residing at Beloit, inthe county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Fuel-Feed Mechanism for Internal-Combustion Engines, of v*which the following is a full, clear, and
exact. specification.
n invention relates to fuel feed Vmechanism for internal combustion engines, and in particular to such devices as are used in a vdual capacity for either controlling the mixture of liquid hydrocarbon and air or of air and gas, depending upon the vadjustment of the various parts of the mechanism; the object of my invention being 'to provide -ag mechanism simple in construction, comprising few parts, capable of easy and quick manipulation, l'and eiiicient in operation.

When liquid fuel. is being used the'valve is in the position shown by full lines in Fig. 2 closing the opening between chamber 12' pand chamber l and permitting air to be drawn directly from chambers 16 and 15 -past the fuel nozzles 11 for vaporizing thefuel drawn'therefrom. When it isdesired that a mixture of gas and air be used,'the
mitted tofenter thejslot 31 lin a manner to retain the valve in 'its position. of adjust-L ment, .wherein it closes the opening for the and uncovers the opening between chambers -12 and 1, permitting a1r tobe drawn through the'valve controlled opening between chambers 12 and 1G/'and .gas through the ports.
