fThe 2. present invention relates to carburetors, and particularly tofcarburetors for mixing airfand liquid fuel for internal combustion engines.` f 1 An objectofhe invention isto provide a carburetorr'by whichy theliquid fuel is vaorized before itenters y. the. intake mani- A 'furtherobjectpf 4the invention is to provide a carburetor having aheatlng de-` vice associated therewith and adapted to asi carrying the upper and lower pivot pms 17 sist in the vaporization ofthe fuel.
Another object of the invention is to provide a carburetor having a rotary fuel-rece'iving member. with means whereby it is operated by air pressure from the air-intake.
Still another object of the invention 1s to provide such a carburetor with means for automatically cutting ofi' the fuel suppl when the engine is not running, and wi means for regulating said fuel supply.
A still further object of the invention is to provide arcarburetor, and particularly a carburetor-having a rotary member with an electrically heated member for vaporizing aliquid fuel.
Other objects and advantages of the invention" will appear 4fro'rn the following description taken =in connection with the accompanying drawings, which' illustrate one preferred' embodiment`rv thereof andy in which: f
Fig. *1 isal vertical sectional view of a formyof carburetor'l embodying the'` present invention;"' l
Fig. 2V is'a sectional view taken on the line i 2-2 of Fig. 1in the direction 'of the arrows.
Referring 'finpdetailf tothe drawings, Ya casing =11*'1s provided with an air'intake ,opening 12 at one` end thereof, in `which is ."mounteda springand bearing housing 13,
, which is v re l erably made of insulating materialfan lwhich maybe supported/g upon a centrally `located plate 14, ormin'g 'a part of the casing 11,` or isupportedzfromgitby lwebs or other desired means. y f
In the y'lower end 'of thevhousing 13 is mounted a spring such 'as the coil spring 15, shown, and resting `on'sai'd springis ,-a lower bearing member 16 adapted to receive the lower -end of a pinv 7. f
The pin 17 fits within aninsulating member 18 at the lower end thereof, and inthe upper'end thereof is mounted anI in 19, supported in an upper bearing mem r 20, which is slidably mountedlin the stationary housing 21, `fixed within the upper casf.
ing member 22 by means of spacingand supl. porting webs 23, or by other desired means.
A spring 24, mounted the stationary member 21, urges downwardly the upper bearing 20, and is preferably under suii;VV
cient tension to overcome theifaction'of the spring 15, and the insulating member 18,
, and 19, respectively, is thus yieldably held for' rotary motion between the two coil springs. l
Centrally 'fixed to the insulating member 18 is a fuel receiver 25, preferably cupshaped, as shown, and having a `depending annular iiange 26, through which the in- The housing 13V is provided with an inner annular shoulder adapted to receive` a ring 30 of metal lor other conducting material,
with which a wirev contacts conducting an electric current. The ring 30 is mounted -in the upper part of the housing-13, vand whenJ the rotary fuel receiverv 25 is moved axially in operation, the lower bearing' 16'moves with it under thefyaction ofthe spring and comes in contact with the rin 30. f
The ring 3 0,v the lower bearing 16, `thepin 17, thering or collar 27,l and the rotary-` fuel 1- receiver, including the flange 26, are thus' adapted lto conduct a current yof electricity,4
which may be'y carried tothe housing 13 by a wire 29 from .any suitablesource to the i rotary fuel receiver. y
The, particular heating v.device herein i' i vshow'nli'n the resent embodiment of the inyention has-.t e form of a wire `31` secured 1n any convement manner to a circular insulatingvv strip 32 disposed about the rim or outer\ edgeof the rotary fuel receiver 25.
The upper bearin Vmember 20 yhas its lower portion space from the stationary housing 21 to permit the passage there?.
through of a liquid fuel which enters into the opening 33 from ay channel 34, provided with a valve 35, o erable from without the casing and controing the supply o-f fuel v which enters the carburetor from a feed pipe point 37, where said'wire is soldered, welded, v or otherwise secured to said -fuel receiver.
Afterl passing about the edge of the fuel receiver, the wire/ 31 is bent radially inwardly, as shown at 38, and contacts with the upper bearing pin 19, which conducts the current through the upper bearing member 20 to the housing 21, where the circuit is grounded. 'lhe stationary member 20 is spaced from the upper housing 22 to provide an annular channel 39 leading to the intake manifold 40. In operation the liquid fuel is fed from the supply tank through the feed pipe 36 into the channel. 34, and downwardly through the chamber 33 into the rotary receiver 25. The intake of air through the intake opening 12 causes the fan blades 28 to rotate, and these blades being fixed with respect to the rotary fuel receiver, cause said receiver to rotate at the same angular velocity as said blades. This rotary motion causes the liquid fuel to be spread in a very fine film over theinner surface ofthe fuel receiver and to be thrown radially outward under'centrifugal action to the upper and outer edge of said receiver, where it passes across the heating wire 31 and is thrown off the fuel receiver in a tangential direction caused by said rotary motion in the form of a vapor produced by the action of the heated wire on the line film, the vaporized fuel being then carried through the channel 39 around the stationary member 2O in the form of a vapor into the intake manifold 40, from which it is delivered to the combustion chamber or chambers.
It will be seen that by the above construction there has been provided a carburetor having a rotary fuel receiver in combination with a heating element, by which the liquid fuel is heated and vaporized before it is carried into the combustion chambers to be ignited, and that the upper movable bearing 20 cuts olf the supply of fuel when the device is not operating, owing to the action of the spring 24.
It will also be observed that the ring 30 and the lower bearing member 16 provide an automatic make and'break contact, by means of which a current- Hows through the heating element during operation of the device and is cut ofi' therefrom when the device is not operated. It will also be observed that the heating element in the present embodiment lof the invention is located on the inside of the fuel receiving member ing, a' rotatable heating element, and means in said casing carrying said heating element and operated by intake of air thereinto for delivering said fuel to said rotatable heating element to vaporize said fuel.
