a citizen of theUnited States, residing at ,Olev'elamL-in the county of Cuy'ahoga and State of Ohio, have invented. certain new and useful Improvements in Carbureters, of which the".,fOllQWing is a specification,

reference being bad thereinfto the accompany ng drawing.

- -Tl11S inve tron relates to improvements in earbureters, and particularly pertains to that type of carburetor in which there are two separate air passages, each having a separate oil supply, whereby there are two separate carburetingpass'ages;

The present improvements, as embodied gwebs 5 and 6. The inlet ends of these passages'are each provided with inlet passages, 7, and their outlet ends 8 are each provided with eontrollingthrottles or valves 9 and 10. Eachof the inlet passages '7 is provided withan inwardly opening valve- 11 ,.and these valves slide upon an adjustable supporting rod'12. Arranged in the top of 'the casing'l and coaxial with the valves 11, are the externally screw-threaded valve-rod supporting members 13. Spiralsprings' 14 Patentedqaii. 9,1912.

The=member s 13 have aeeutrallon- 5 gitudinal here or passage 16' through which thevalve-supporting, rods 12 pass, and the upper ends are screw-threaded as shown at "17, to receive the s'crew-threadedportions of the rods 12, whereby the rods areadjusthers 13 tire split longitudinally below their heads 18'by lbngitudinalslits-IQ, and'one of-thedi'vided portions isprovidedwitha longitudinal externalgroove 20; which re-- ceives ,the inner end of aset screw 21. This; screw serves. to hold-the member 13 from rotating after it is adjusted, and by forcing it against the inner wall ofthe groove as ing the valve-supshown in Fig. '11, clam s it to its adjusted porting rod 12 and hol position.

As shown, "the'gasolene sup ly chamber 2, preferably extends below e casing 1, as shown at 22', and has alcentrally located gasolene inlet port 23, which-is controlled .by means of azvalve 24, thestem25 of which is suitably connected with the float'26. The

No claim is made herein for the valve mechanism here shown and described, as this will form the subject matter of a divisional application.

Having thus described this invention, what is claimed and desired to be secured by Letters Patent, is

A carbureter having two I carbureting passages, a vertically arranged fluid chamber located between said passages at a point intermediate the ends of the horizontal passages, the fluid supply chamber having a separate exit passa e extending into each air passage, one end 0 the assageshaving air inlet passages at one si e of the supply chamber and the other ends having throttles located at the opposite side of the supply chamber. 1

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