' Be itknown that I, EUGENv LUDWIG MUEL- siding at Paris, France,.have hve'nted'certain new and useful Improvements in Carbureters, of which the'following is a speciii-- cation. i

Myinve'ntion relates to an improved carbureter combining the advantages of the injection-carbureter,'such as compactness and uniformity in the quantity of fuel utilized, with those of the surface c'arbureters, in par'- The new carbureting device has the additional advantage that the cross-section of the vaporizing-chanber is regulated by a ysingle member, the' air-supply aperture and above and the ioat-chamber c below.

liquid to be vaporized is distributed and prethe mouth of the screw connection to the motor being regulated in the same proportion.

In the accompanying drawings, Figure l represents a vertical section of the vaporizer on theline B of Fig. v2, andFig. 2 is a plan view of Fig. 1.

In place of an injection-nozzle I employ a wick a, which enters the mixing-.chamber b The sented to the air-current by the fick over a relatively large area in astate oi such fine distribution that the vaporization takes place actually at the wick itself and that there is no danger of particles of liquid being entrained and entering the working cylinder. This homogeneity of the mixture' insures silent and at the same time economical working,l

vforthe air, Wherefore it isk much easier to obtain a uniform mixture for all speeds ofsthe motor. The resistance which the wick offers to the flow of the fuel through the device can be regulated by means of the nut il, which displaces the cone e in vertical direction, and

thus presses'the wick more or less forcibly against the corresponding cone fof the carticular, 'the formation of a homogeneousv bureter-casing. The adju-stable lfloat g'enablesthe level of -th'e liquid to be kept constant.

Air is-supplied through the screw-connection'pipe h1. The mouth of the latter where yit enters lthe mixing-chamber b is regulated by an annular, slide t, moving in vertical di,

rection only. For this purpose the slide i is provided on its outside wall with a thread c" of high pitch, with which the Y.iut 7c, .which operates inthe casing, engages, 4The nutk can be -Operated by the handle Z, projecting through a slot in the casing, in which manner the annular slide can be raised or lowered, as

desired,l whereby the crosssection of, the

mixing-chamber and the outlet-aperture fm,

for the working mixture can be adjusted. In-

vaporizers of this kind of large dimensions I preferablv provide a hot-Water jacket to heat the mixing-chamber.v

. W `t I claim isl 1. A carbureter, comprising in combina? tion, a mixing-chamber having an airinlet and a mixture-outlet, a liquid-reservoir located'below said mixing-chamber and presenting a conical wall, a vertically-adjust-able member having a conical wall projecting into the said reservoir parallel to the first said conical wall, and a wick located between the two .said conical walls and projecting from said reservoir into said mixing-chamber, substantially as set forth.

2. A caibureter,comprising combina;`

tion, a mixing-chamber having an air-inlet and mixture-outlet, a liquid-reservoir located belowv said mixing-chamber and preseiiting a conical wall,'a vertically-adjustable member having a conical wall projecting into said reservoir parallel to the first said conical wall, a ,vertically moving sciewthreaded member located in the mixing-chamber and regulating the cross-section of the saine and of the said inlet and outlet passages, a nut fitting the said regulator, and means for actuating said regulator from without the device, and a wick located between the two said conical walls and projecting from said liquid4 ,reservoir intopsaid mixing-chamber, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.l
