To all *whom it mag/:concern: -Be' it` known thatl, J a-L. WALKER, a

citizen of the United Staes", residin .at National,"in the county of Pierce and tate of Washington, have invented certain new and useful Improvements in. Carbureterl'; and ll do hereby declarelthe following tobe a'full,

clear, vand exactdescription ofthe invenw tioinsuch as will enable others'skilled in ,the

art to which it appertains tomake and' use the same, referenceI being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in carbureters and consists in the provision of a simple and eilicient de-i vice of'this nature so constructed as to enable the same to be run upon a heavy fuel,

such as kerosene and distillates and so constructed as to be of easy operation.

My invention comprises various details 'of construction, combinations and arrangements of parts, which will be hereinafter fully described, shown in the accompanying drawing and then specifically defined in the appended claims. A

I illustrate my invention in the .accom-y panying drawing, -in which I have shown a' of the ioats and receive threaded portions of the rod 6V whichY has a hand wheel 6x fastened at one end, whereby the rod may be turned to cause an adjustment intermediate the sameand .the float. The bolts 7 serve not only to hold the oat from turning axially but to guide the same in its vertical movements within the chamber 2. A coupling 9, made preferably of mag;

netic metal, has threaded connection with.

an opening in the bottom of the float chamber and has a laterally extending duct 9* to which the coupling 10 is connected. The

lower end of the coupling 9 has a valve seat 9 and a rod 6 passes through the coupling nSpeedmtion of Letters'atent. applipauonnied July 22, 1916. srial No. 110,734.

A float 5 Patented Oct. 2, '13917.

9 and is provided for theupurpose of unseating the ball valve 8 whichnofrmally 1s held to its seat, formed at the lower end of thecoupling 9 by'magnetic attraction and` may be unseated by pressure appliedyto the rod 6. A gasolene"`supply pipe, designatedV by numeral 11, is connected to the union-11.x

landforms means whereby fuel from any suitable source of supply may `pass to the interior of the coupling 9, thence .through thecoupling 10, through the duct l'foimed. inthe wally ofthe member 13. Said mem? ber 13 is fitted within the body of the cal"- bureter 1, which latter is provided with 'air openings 18 and the member has similar air openings 18, formed in the bottom thereof..

yThe ehambered portion of the member at its lower end has interior threads to receive the .adjusting plug 19, which latter has a duct 19X through thei'wall thereof, leading into anannular recess19, forming a chain ber in which the fuel enters before passing into the interior of the plug 19. The upper end 'of the plug 19 has an opening 19a which iscontrolled by the needle valve 16", and

16 designates a piston secured to the rod '.15

and is movable therewith inside of vth chambered portion of the member 13.

4 A sleeve or piston 1,2is movable within the carburetor 1 and has an opening,the walls of which incline from the central contracted portion 12 through which contracted portion the member 13 passes. A wire 20 is bent bail-shaped and ha's its ends fitted into the sleeve and passes through apertures'18.'

in the bottom of the member 13 and is bent about the plug 19, and which wire is pro* vided for the purpose of limiting the upper movement of the sleeve and thereby avoid injury to the needle valve and other delicate parts of the device and also serving as-a means for holding the sleeve down, if desired, in startin the carbureter. Secured to the pistonor s eeve 12 are the spider arms 17 which support the mixing? plate 14, the latter being centrally apertured for the reoeption` of the stem 15, having a loose connection therewith, so that it may shift but is adapted to be raised and lowered in the plate 14.- and sleeve 12. The plug 19 is adjustable within the lower end of the member 13 and is provided with a drain cock 21 in the lower end thereof.

-Mounted within theexhausted chamber 3 is a small lioat chamber 22, the upper'end of which Vhas an opening 22,I the -wall'- of which forms a valve seat for the tapering valve t28 at the upper the 'float 23. A ,pipe 29 leads freni the opening in the top of 4the chamber 22 and leads to and communicates with e three-Way union 25 from which t a pipe-25 leads the interior of the carburetor chamber l., andy@ designates a pipe leading from the threes/ay union and communicates with thev gasolene tank 24, the pipe 28 being 4providin ed with arent 26 to the ati'nosphere.

` t water pipe 2'? leads through the -top of Ithe heatingchamber 3 and. coils about the lloat chamber 22 and communicates with the opening at the lower end of said chambei' 22. An exhaust pipe 30 communicates with one end o the exhaust chamber 3 and an exit exhaust pipe 3l, end' oit vsaid chamber 3.

ln operation, when. a slight vacuum is formed in the carbureterabove the sleeve i12, the latter isiraised according to the speed of the motor andwillpermit air to enter thev Carburetor landv in its movement the needle valveis lifted, admitting fuel according to the quantity 'ot' air admitted. The fuel y passes 4out through the top of the jet and .comes in Contact with the lower surface of the mixing plate lll. Air entering between 'i mixture and downwardl tor a rich mixture,I

the needle yalvebeing tapered for the different speeds. The fuel levelv may be adjusted by screwing' the' rod 6 up or down through the float 5, the latter being held from turning by means of the bolts. The water passing through the pipe enters the heating 'chamber 3 and into the tloat chamber 22, causing the'lloat 23 therein to rise, making it impossible fior water to pass through the float chamber 22 but, as the water becomes heated,'steam will be generatedand 'force the Water downward in the float chamber and the-float will lower and force the steam outl at the opening in the top thereof, and the steam passes through the pipe 29, coiled about the float chamber and .thence passes through the threewvay union 25 and enters .i in a superheated condition the upper porso tion ol the 'carbureterchamben An automatic piming 'device is provided through the medium ot the pipe 2. it the starting of the 'motor there no steam and to and coi'iniiunicates withy leads from. the exit y ture at one end, a stem the ad usting 4 shannon water will not )ass 'throughthc chamber '22 andthere will he a suction through the 65 pipe Q8, drawing gasolene `from the tank 24 and afterward air through the vent 2o which, mixing therewith, will be drawn into the carburcter through the pipe 25K. When the apparatus is in operation and steam Iis7ol produced by the water being heated by the exhaust :from the engine, the suction will 'be overcoineby the steam and the feeding of the gasolene will stop, thus priming the carbureter only when there is no steam to assist in yaporizing the heavy fuel.
