Be. it i-mowii that ERNEST lil. ERG11- ERICBL, a eitizen ef the United. Stm/es et America., residing et Detroit., in the ceunty of Wayne and State 01E Mieiiifgzm, have invented` eeztsin new and usefil imprevemeiits in Cariiureters, et' which the fniievvv ing is a specification, reference being im@ therein to the accompanying drffwiugs.

This invention reiatee i0 eau'buretes for internal con'ibustion engines, and especially to eetain features of construction of the liiei supply mive and Hoet chamber by which simplicity, readiness of adjustment, and certainty ef action in different positions are obtained.

The invention consists iii the matters hereinafter set forth, and more pei'i'iicnlarly pointed mitin the appended claims.

Referring to the drawings, f. igiu'e 1 is e View in iongitudinalsection through s, eau?- buretei which embodies features et the iiivention, Fig. 2 is a View in sectimi en. line -m of Fig. 1.

l[in the drawings, the base of the eerbureter is a. vertically disposed metal e inder, Whose bottom l is preferably integizil with. its side wall 2; an axial hollow, Geniaal core 3, likewise preferably integi'iil with the bottom., extends up thrmig'h the cyiinfier and the ammini' space between the com smi eide Wall wmprises a float chamber.

5.11 uuxiiiity duel' 2:33 is formeel im the eene stem 28, its upper end opening into a cup shaped mouthv 34 close to the main duet valve seat and at about the upper level to be maintained in the float chamber contr-nts. Its lower end opens horizont-ally into the float chamber.

A drain' is provided for the tloat chamber, which consists of a depending nipple 35 on the chamber bottom interiorly screw-threaded to receive a screw-plug 36 which normally closes an oblique duet 37 in the nipple wall.

A vaporizing chamber 38 with deiieetors 39, air inlet valve 40, outlet valve 43, gasolene valve 41 and throttle handle 42, is secured over the floatchamber7 the mechanism and design being of any approved type, and not per se forming a part of this invention.

In operation, the float always aets upon the gasolene inlet valve to maintain a eenst-ant. mean level in the chamber regardless of any tilting or agitation of the carbureter, owing to the universal connection between the rmgr and lever. The level is readily determined by inspection of the gage glass, and if not correct, may be quickly varied by slackin the shield nut, raising the latter clear o' the notched bushing, and rotating the shield and the stem, so as to Work the lever nut up and down and thus change the vertical position of' the float in the chamber, and thereby shift the level.

The gage glass serves as housing for the fuel valve stein and allows the operator to instantly detect any lodgment or stickingv of the valve from impurities on the valve seat which is visible.

The position ot the cross duet in the tloat chamber prevents the entrance ol Water into the vaporizing chamber. as it is trapped in the lloat chamber below the duet and may be drawn olf through the drain cook. Likewise any lighter grade stays at the to the valve receiving a supply ot' substantieilly average and constant density.

The design and ronstruetion may be varied without departing from the. spirit ot' the invention and l do not care to limit myself to any partirular form or arrangement of parts.
