To @ZZ 'whom 'it may concern.'

Be it known that l, lVAi'fren C. Wns'r- AWAY, a citizen of the United States, residing at Rockford, in the county oii llfinnei bago and State of' Illinois, have invented certain new and useful Improvements 1n Carbureters, 'of which the'iollowing a description My invention belongs to that general class of devices designed to thoroughly coniiningle air and ay suitable. liquid, as J@or ezainple ahydro-earbon, and has for its object theproduction of a similar, eheaper and more eilicient device for the purpose.

To this end niy invention consists in the novel-construction, arrangement, and coinbination-offparts herein shown and described,

and more particularly pointed out in the claims.

Inthe drawings Whereln like reference characters indicate like or 4eorrespoluling parts: Figure 1' isa partial vertical. sectional Fig. isa cross-sectional vien7 of the saine taken online Fig. 3 is a View of one side inelevation. Fig. 4 is a. view of the opposite. side in elevation. F ig. 5 shows niy preferred form of liquid valve, the ports shown in dotted lines. Fig. 6 is a sectional view ofthe saine taken on line G-G of Fig. Fig. 7 showsr my preferred orni'o valve, in

' a slightly different vposition relative to the port openings. Fig. 8 shows the saine, the

`-valve shifted until the port openings are Wide open. Fig. 9 is a partial vertical sectional View of a modified form of device, and F1g.'10`1's a top View of the device shown in the several figures. y Referring te the drawings, 1 is abase and 2'atop for a shell or easing forminga mix 'inggehamberf The base and top may be erably integrally Connected to the part 2 seeured :together lin any .suitable or preferred Way. As is shown in the drawings (seejFigs. 2,- 3 andv 4t) lags 3, 3 suitably formed on the twolparts 1 and 2 serve seats for the clamping bolts 4L or their equivalents, which securely holdthe parte together.

Within the mixing chamber is. a suitablev spreaderfor ba-tile, 9 (Figs.-1-and'2)', pref-l as at 10, but arranged so toleave an open space 11 between it andthe part 2. It4 is o viens. that if.desired.the-spreader may be madeseparate from the 'part- 2, and secured may ine-ans. The-top 2 is preferably extended as at 2, and a -valve seat 13 arranged thereon as shown. Means for conducting a liquid t'roin the valve seat to substantially the eenter of the under part of the spreader is provided, the preferred construction being to have the duet 12 for that purpose arranged wit-hin the spreader as shown. Any suitable means niay` be employed for conducting the liquid from the supply pipe to the vali-e seat, a second duet 15 extending from the supply pipe opening at 15 to the valve seat isshoivn for the purpose. A valve 14' for 'oon-- trolling the passage of liquid.z through the duets 15 and 12 to the spreader is provided', the construction and opera-tion of which will be more fully explained hereafter.

In the preferred construction, suitable means are provided'for admitting air to the mixing chamber, as shown an opening 8 is arranged ior that purpose. The base 1 pref# erablyextends into the mix-ing` chamber forming a nozzle as at 7, and is with a chamber G formed by thewa ls 5. It

rovided."

in the preferred position by any suitable is obvious that the extension 7 ,-v or the Walls* the amount of air adn'iittedA to the chamber 6 is shown, the construction and operation 'being more fully explained hereinafter.

In the upper partvv of the top 25 is provided an outlet opening 17. As--shovvnthe-top is extended as at 18,- and 'suitable ineensprovided for attaching the same to a-pipe, en-

Oine or the like,

aetory.

My preferred form of' valve for control-- ling the liquidadrnittedtothe duct'12eon; sists of' the member 14 pivotally seeuredto` the'top 2 as at 19 (see Fig. 3). The valve is'seeurely held on its seat 13 by the inem.- ber 2-1 secured to the top 2A as at 225. the member 20 and the resilient means-23J- The part 20 preferably eX-tends out as at 20 to loosel engage 21, in order that the part-2U' retained in asuitable position to perform `its functions inholding.: the valveon its. seat. The 'construction of the-valve'- is clearly shoivnin detail in Figs-...5, 6,7' and 8.- A. depression 14.- is formed vin vthe valve on the side that. seats on the valve sent lugs M beingfound satis@V 13. When the valve is substantially in the position shown -in Fig. 3, the ports (as shown in dotted lines) are closedand liquid prevented from passing from the supply pipe, through duct or ort to the port or duet 12. As the va ve is operated the ports are gradually opened to each other as indicated 1n Figs. 5, 7 and 8, as shown being Wide open in the position in Fig. 8.

The preferred torni of valve for regulating the amount of air to the chamber 6 and opening 8 is most clearly shown inF ig. f1. The part 34 is pivotally secured to the base l as at 36, and carries one or more ad'ustable members 16, ywhich are adapte to cover or partially Icover the opening to the chamber 6. It, is obvious that instead of using the adjustable members 16, held by the screws or otherv suitable means, a flat not adjustable member might be used, that is the member 3ft might be of a shape adapted to cover the opening to the chamber (i. rl`he top 2 is also preferably provided With extensions 24C, or their equivalent, adapted to hold the member 25, to Which is secured the lever or armV 40. (See Fig. l0.) i Any suitable means may be employed to operate the inlet valves, and the same may be operated separately or s nchronously as is de sired 'or preferred. bly preferred way and means are substantially as follows. Arms or levers 2G and-30, or their equivalent are se cured to the member 25. The liquid valve and air valve are connected to the arms 2V and 30, by means of the connecting members 2'( and 31 pivotally secured at the points 29 and 28, and 33 and 32, to the valves and arms respectively. It is obvious that the extent to which either of the valves is opened depends upon the rotation or movement of the lever or arm 40, and Vthat the two inlets are opened synchronously and to a predetermined extent relatively to one another.

,In my preferred forni of construction as indicated in Fig, 9, the spreader 9 is extended downward as at 37 or substantially dome shape, it being obvious'that the ex?. tension may be separate from t), as shown,

or integral. 4ln this form' the member 38, substantially as shown, may be provided.

'lhe mode of operation of my improved device is substantially 'as-follows. Normally the solid portion ot the valve 14 covers the port 12 and Vprevents the passage of liquid into the port. or duet- 412, and into the mixer.

lllmirrotating the lever VKl() the valve moves and gradually uni-overs the port 12 and the liquid passes from the supply pipe through the duct I5, through therrecess 14 and into theI dile-t l2, thence into the mixing` chamheifl' By thesame movemeutof the arm 40, the air valve16 is opened and air is admitted to the mixing chambeithrough the rhamber and openiimr 8. 'lhe incoming air strikes` the spreader and the incoming liquid. The liquid and air commingle and (in the simple form of device shown in Figs.- l and 2) pass up through the opening 1l and thence up and out through the outlet or opening 1T to the engine or other desired place. lu the preferred form shown in Fig. t), the mixture passes down and under the edge of the extension 37, and then upward through the openings l1, and out of the outlet 17. As is shown a small opening or duct 39 is preferably provided opening down into the chamber 6. Any Waterl thatl may form or be in the mixture chamber owing to moisture in the air or other causes, or any excess of liquid from the liquid inlet duet, will run ott through this opening to the chamber 6 and out, or else be drawn back into the mixing chamber in the form ot vapor or gas. In this manner the flooding ot' an engine or the like, With the liquid is practically done away with. The lever or arm l() is preferably provided With an extension 423, and also an extension 41 and an adjustable member 42. These extensions and the adjustable member serve to regulate the travel of the arm 40. An adjustable member may be put on the extension 43 if desired, or any othersuitable means may be employed instead of these extensions, to regulate, the movement of the lever 40.

lt is thus seen that l have an eliicient and very simple devire for accomplishing the purpose set` forth, and as it is obvious that ythe arrangement of the various parts as shown may be altered and other various immaterial moditeations made without de parting from the spirit of my invention, I do not therefore Wish to be understood as' limiting myseltl to the', exact construction and arrangement shown.
