carbureters employed in connection with internal combustion engines, for converting the liquid fuel into a gaseous mixture for motive purposes.
It is well known that the speed of automobiles, aeroplanes, y and like structures propelled by explosive engines may be increased by advancing the time of ignition of the explosive mixture, increasing the supply of air to the explosive mixture, and also by increasing the quantity of explosive mixture in proportion to the increasing speed. It is therefore customary to provide explosive engines or structures propelled by them with means for advancing the ignition and for increasing the air andv fuel supply in order to obtain greater' efficiency of operation. The means above referred to for increasing the air and fuel supply to form a properly proportioned mixture have to a great extent proved 1naccurate, often supplying the fuel and air in improper proportions for the speed at which the engine is running.
It is an important ob'ect of our invention to provide a' mechanism which will deliver an exact proportion of air and fuel for carburation best suited for thespeed at which the engine'is running.
A further object is to provide a carburet- Aing mechanism in which the air and fuel supply tothe carbureter 'is positively. increased or diminished in exact proportions to the speed at which the engine is running,V
being operated in connection with the engine throttle mechanism.
A still further object is to provide a mechanism in which the fuel and air supplies are simultaneously regulatedI -Another object isA the provision lof a mechanism in which the airand fuel supply chamber is connected directly to the intake manifold of an engine, and in which the mixture outlet passage leading there from is free from obstructions.
An embodiment of our invention herein disclosed may be generally describe-:l `as comprising a mixing chamber havingfuel inlet and gas outlet openings controlled vby reciprocating members provided with openings, said-openings adapted to be brought into `or out of register on a reciprocation.
thereof, -fueldelivery valve being located within said chamber, both members and fuel valvebeing `operated in unison; and
controlledffrom the throttling mechanism.y
Vfeaccomplishv the above objects `by means of the mechanism herein described ings, in which; l
VFigure l, is an end elevation ofourcarbureter.
Fig. 2, is a central vertical section on'line'22 ofFig-Ql.
' Fig. 3,' isa plan view vof the Amixing chamber, and fuel delivery valve, the gas outlet leading therefrom being in section. y
Fig. t, is a transversesection through the mixing chamber taken on line 4--4' of Fig. l.
Referring more particularly to the drawings, we desire to state that'we have not illustrated a Hoat chamber in connection with our invention, as. such mechanisms are well known, and furthermore it does and illustrated in the accompanying draw# l taken not form a part of our invention, any well shown in Fig. 2 of the drawing, terminat-` ing. in aflanged end'S adapted to be `bolted or otherwise secured to the lower end of an intake.V manifold of .an explosive engine.
`Telescopicallv mounted within `mixing` chamber 5. are cylindrical tubes. 9 and l0, each having a wall ll closing the outer end thereof. Tube l0 telescopes within the chamber 5, while tube 9 telescopes within tube l0, as clearly shown in Fig. 4 of the drawings, the difference in the external diameter of tube 9 andin the internal diameter of chamber 5 being provided for by means of an annularl bearing flange l2 formed on one end of chamber 5. Tubes 9 and l0 are each provided with air inlet Aopenings 13,14, and mixture outlet openingsl 15 and 16, saidopenings being preferably rectangular in configuration, the outlet openingscommunicating with the mix-` manifold (not shown). Y
are approximately 'the sain-e length as cham-V ture outlet pipe leading to the'engine rlubes 9 and 1() ber 5, so that when the tubes are nested therein the openings `13and 14 will be out of register', and will close air 'inlet openings 6 entirely with the exception of a very small aperture, which is necessary to insure the admission of sufficient air to chamber 5 required by the engine when idling.
The mixture outlet openings 15 and 16 formed Vin tubes 9 andV 10 control the volume Yof' carbureted mixture admitted to outlet pipe?, said openings being oppositely'disposed to. the air inlet openings 13 and 111, and operating simultaneolisly therewith. The area of the mixture outlet opening in the mixing chamber is slightly greater than the air inlet opening, thereby insuring the delivery of the entire volume of carbureted mixtureV to the engine cylinders.
The bottom of mixing chamber 5' midway between its ends is providedwithaperture 20, fuel inlet pipe 21 passing therethrough and terminating within the chamber at approximately thecenter thereof.l The end or pipe'21 forms a nozzle within chamber 5 and is provided with a cone shaped valve seat 22, and the Vwall of said chamber directly opposite valvef seat 22 is provided with al Y circular aperturedneclr 23 exteriorlythreadi having a plurality of arms 28, 29 and 30;
Pivotally connected to lever arms 28, 29, which are oppositely disposed, are operating rods 31, 32, the outer end of said-rods being pivotally connected to brackets 33 and `34 i respectively, which are rigidly secured to the outer ends of tubes 9 and 10 at the outer endthereof. Arm 30 of lever 27 is pivotally connected by a pull rod 35 to a verticallyY disposed rock lever 36, said lever being pivotedY to one side of the mixture outlet tube .7, as clearly shown in Fig. 3 of the drawings. Pvotally secured to the upper end of lever 36 is an operating pull rod 38 which extends rearwardly and is connected tov toot and hand operating levers of usualconstruction (not shown). If desired, the pitch of the threads formed on the upper end of valve stem 25 may be varied to cause the valve stem toV rotate more quickly or more slowly, as desired.
In order' that the valvev stem and fuel inlet pipe will not interfereV with the reciprocal movement of tubes 9 and 10, we haveprovided longitudinal elongated slots 39 and 40 in the walls of said tubes, said slots being oppositely disposed and surroundingthe i'ii,
rlhe operation oiz our mechanism will be clearly apparent from the foregoing description, andy it will be seen from the above that we have. provided asimple mechanism whereby the vair inlet, the fuel supply valve u and mixture outlet openings are all controlled in unison, the increase or decrease in the size of the various openings, including the operation of the iiuel'supply valve, being regulated so as to :form a -mixture best suited for the engine at the speed at which it may be running. Y
' What we claim is: Y
A carbureter comprising an open ended cylindrical mixing chamber having oppositelliyT disposedair inlet and mixture outlet openings in its wall, a pair of cylindricalV members each having la pair oiV oppositely Ydisposed openings therein reciprocatingly mounted in saidnmixing chamber, the outer ends of said members being closed, a fuelv `valve mounted in said mixingchamber` andV a single means to reciprocate said cylindrical members and to regulate the' amount or fuel delivered by said valve.- Y f In witness that we claim the oiegoingwe have hereunto subscribed our names this 18th day of February, 1918. i
