UNITED STATES PATENT OFFICE.
WILLIAM S. GUTHRIE, OF LOS ANGELES, CALIFORNIA, ASSIGNOR TO MARVEL CARBU- RETEB COMPANY, OF FLINT, MICHIGAN, A CORPORATION OF INDIANA.
CARBURETOR FOR INTERNAL-COMBUSTION ENGINES.
Original application filed April 3, 1919, Serial No. 287,277. Divided and this application filed September 8, 1924. Serial No. 736,597.
This invention relates to carburetors for internal combustion engines and is a division of my application filed April 3, 1919, Serial Number 287,277 for carburetor, the object of my invention being to provide an improved construction of reservoir with a float for controlling the supply of fuel thereto.
Another object of my invention is to provide a carburetor with a fuel reservoir havlO ing a float through which loosely extends a stem so as to permit freedom of movement of the float in respect to the valve.
The invention especially consists of certain details of construction shown in the drawings and more fully described and pointed out in the claim.
The drawing shows one embodiment of the invention.
Referring to the drawing, the body 1 has a main fuel reservoir 2 in which a float 3 controls the fuel valve 4. to open and close the inletpassage 5 to which the liquid is conveyed in the usual manner.
The fuel inlet valve 4-in the present case a needle valvein the embodiment shown is preferably guided at both ends so the valve will not get out of line with its seat and thereby impair the same, and it has two portions of different diameters, the smaller of which passes, preferably rat-her loosely, through the float 3 and in the present. case guiding the latter; and a cross pin 10 or the equivalent is provided on the valve some-' what below the bottom of the float. It will thus be apparent that the float may have considerable free movement to accomodatc and vibrations and relieve the valve seat largely from shocks itwould get if the float and valve were closely connected. The con struction is exceedingly cheap (the use of interposed levers or the like being eliminated), and it may be applied to devices other than carburetors.
The liquid flows out of the reservoir through suitable passages to a main passage 29 and then to the nozzles 30 and 31.
lVhat I claim is A carburetor comprising a carbureting chamber and a fuel reservoir connected thereto, a removable cover for said reservoir provided with a fuel inlet passage terminating in an enlarged passage forming a guide way, a valve seat formed at the junction of said passages, lateral branch passages extending from the enlarged passage within said fuel reservoir, a valve mounted in said guideway cooperating with said valve seat and having a reduced portion, a guideway formed in the bottom of said reservoir in which said reduced portion is slidably mounted, a float loosely mounted on the reduced portion of said valve and a pin extending through the reduced portion of said valve below said float. I
In testimony whereof I hereunto aflix my signature.
WILLIAM S. GUTHRIE.
