VTo @ZZ whom it may concern.-

Be it known that we, WALLACE S. OLDs and DAVID M. HOUGH, citizens of the United States, residing at St. Louis, in the county of Gratiot and State of Michigan, have invented certain new and useful Improvements in Carbureters, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention has reference to a carbureter particularly designed for with explosiveengines; and our invention consists in the construction of a novel device of this character and in the combination of its various parts, as more fully hereinafter described, and shown in which Figure lis a vertical central section thro ugh a oarbureter embodying our invention; and Fig. 2 is a cross-section taken on line a; fr, Fig. 1.

In construction the carbureter comprises an inclosing casing A, having a closed upper end B and terminating at its lower end in a neck portion C, as plainly shown in Fig. 1. The casing is provided with an air-inlet port D in proximity to the neck portion and with an outlet-port E near its top. y

F designates an outlet-pipe communicating with the interior of the casing through the port E,through which the mixture passes to the engine in connection with which the carbureter is adapted to be used.

Gr represents the air-inlet pipe, through which air enters the carbureter through the port D. This pipe may be of any approved construction. Freferably, however, vided Vwith a closed end a and has formed therein in proximity to said end lateral airinlet ports b.

The neckportion of the carbureter before referred to is formed, preferably, in the following manner: I-I designates a threaded nipple engaging within an aperture I in the lower portion of the casing, and J represents a T-coupling, which has `a threaded engagement with the nipple referred to and is provided with an overllow-pipe K f In the free end of the T-coupling isarranged a bushing L, which forms a restricted passage within the neck,` and M is an elbow having a threaded use in connection the drawings, in

`.The gasolene or any engagement with the bushing, and O is a supply-pipe communicating with the elbow.

Arranged within the casing is a liquid-discharge device P, which is in the form of a discharge-pipe Q., the lower` end of which is fitted Within the plate R, which is preferably conical in configuration andwhich also has formed in its upper face a valve-seat S. y

'T designates a valve adapted to be seated upon the deliector-plate, and `U is an operatL ing-'stem for said valve,which extends through an aperture o' in the casing-top. The stem is threaded, as at d, at its upper end to engage a corresponding thread in the aperture, and V is an operating handle or head upon the portion of the stem which projects beyond the casingl The operation of the device is as follows: volatile liquid that is found preferable in use passes through the supply-pipe O to and through the discharging device. The valve is raised from its seat to permit the liquid to pass in a thin film over the conical head or delector-plate and in a suicient quantity to drop from said plate to the bottom of the casing. The air entering theinlet-port D evaporates the greater part of the liquid film upon the spreadereplate and also a considerable portion of the drops as they pass down through the air-current, and the mixture or vapor is discharged through the outlet-pipe F to the engine to be used in the ordinary manner. The valve T may be regulated so as to produce the desired flow of liquid through the discharge device, and the residue of the liquid which is not discharged with the air through the outlet-pipe is conducted away from the carbureter through the overflow-pipe K.

It will be observed from the construction of our carbureter that means are employed for spreading the liquid, so that the evaporation of the latter will be more readily e'ected. It will also be seen that by arranging the parts in such manner that the liquid will drop through the air-currents a still further evap oration of the liquid may be obtained.

What we claim as our invention isV 1. In a carbureter, thc combination of the bushing L. Upon the top of the discharge-pipe is an apertured deiiector- ICG mixing-chamber provided with an air inlet and an outlet port, a liquid-discharge pipe extending Within the chamber, an apertured Spreader-plate upon the free end of the d ischarge-pipe havinga valve-seat formed in 1ts upper face, a valve controlling the discharge from the pipe, an operating-stern for said v3.1 ve extending through and having a threaded engagement with the casing, and an overlowl pipe leading from the casing.

2. In a. carburetor, the combination with an inclosug casing terminating at its lowerend in a. neck portion and having a closed upper end, the casing being provided with a.

lateral air-inlet port and a similar outlet-port,- a liquidLsupply pipe communicating with the interior of the neck portion, a liquid-discharge pipe Within the casing having one end extending within the neck andcommunieating with the supply-pipe, an apertured spreader-plate upon the free end of the discharge-pipe, said plate having a.' Valve-seat formed in its upper face, a. valve adapted to Seat upon the plate, an operating-stem for said valve lextending through and having a threaded engagement with the closed upper end ofthe casing, and an oVeriiow-pipe leading from the neck above the supply-pipe, substantially as described.' p

e In testimony whereof we affix our signapuree in presence of tWo Witnesses.
