To all whom it may concern.'
' Be it known that l, @ARLEY GOULD Wm, a citizen of the United States, residing at. North Chatham, in the county of Barnstable and Connnonwealth of Massachusetts, have invented certain new and useful, Improvements in Auxiliary Ccrbureters, of which the following, taken in connection withthe accompanying sheet oi drawings, forms a full, clear, and concise description.
The present invention relates generally to improvements in menus for supplying a combustible mixture to internal combustion engines and particninriy to the starting of the en 'ne as hereinafter described.
he ,principal oby'ect of the present invention is the provision of means acting auxillary to the carbureter whereby a proper pro ortioned rich and thoroughly vaporiz com ustible mixture will be delivered to the cylinder or cylinders of the engine for the initial or starting impulse and until the engine assumes its normal condition of operation.
A further object of my invention is to provide a device as aforesaid which will cause the engine to start more easily -and enable it to prlll a load from its initial impulse which is quently impossible under existing conditions where the carbureter alone must be de ended upon for the proper mixture.
y inv tion further comprehends a manually o erated device whichwill effect a saving in fuel and permit of u liner or closer adjustment of the oarbureter; which willbe simple in construction and may be economically manufactured and assembled, and which may be readily attached to and made a. `part of the power-plant of which an intermal combustion engine is the power unit.
Various other objects and advantages of my deyice will be apparent as the description proceeds.
Briefly stated, my invention comprises an auxiliary carbureter which communicates with the float chamber of the main carbureter and with the intake pipe of the engine and by the arrangement and operation of, its parts as hereinafter set forth will thorou hly vnporize the mixture passing thereto fgrom the float chamber of the carburetor and. delivcr a rich full charge to the engine cylin- I will now roceed to describe my invention with re erence to the accom anying drawings wherein, for the sake of c earness I have shown my invention as applied to a motor vehicle power plant, though I would have it understood that it is equall applicable toany form or type of power p ant employing an internal combustion engine, the essential elements of novelty being more particularly set forth in the appended claims.
In the drawings:
Figure 1 is a diagrammatic view showing the relative position of any device to the en ine `and main carbureter, and
ig. 2 is a sectional elevation of my device showing its relation to the main carbureter, a fragment of the latter being illustrated.
Referring now to the drawings in detail, in which like characters of reference are employed to designate similar parte throughout the several views, 7 indicates an internal combustion engine of, the four-cylinder type having the usual cooling and fuel supply systems, the main carbureter being indicated by the reference character 8.
Communicating with each of the engine cylinders is the usual intake or supply pipe 9 connected to the carbureter 8 and delivering fuel to the cylinders in the well known manner, the fuel level within the carburetor being indicated by the dotted line a-a.
The auxiliary carburetor 10 is refcrably mounted adjacent to the main car ureter 8, as shown, in a position whereby the gasolene or iluid level indicated by the dotted line a-a will be common to both the main car bur-eter and the auxiliary carburetor. To cheapen the cost of manufacture and facilitate assembling, I have found it desirable to make the auxiliary carbureter in three parts or sections, the main or body section being indicated byll and the up er and lower section threaded thereinto num ered 12 and 13 respectively. The outer ends of the upper and lowerV sections are preferably formed1 with nipples to receive standard connection or copper tubing wherebythe auxiliary carbureter has communication with the engine 7 and the main carbureter 8, the connection 13 leading from the up er end of Vthe auxiliary carburetor 10 to t e highest point in the intake `pipe 9 common to all of the cylinders of the engine 7, the lower end of the auxiliary carbureter4 being connected to a ipe or tubing 14 opening into the Boat cham er of the carbureter 8.
The body or main section 11 of the auxiliary carburetor 10, is provided with a centif i.
' tral bore or passageway 15f extending verti-4 cally thereof, this passage-way communicating a housing tion of the bore .which th air p oirts 28 have communication ing with a vertical tion 12 and also with the passa e 1 lower section 13, as and for t e puigroses which will be hereinafter explained. lateral bore opening into the passage 15 and iudicated by the refference numeral 18, is provided in the central section or portionll, a sleeve 19 being threaded into said member contiguous to said lateral bore and providor seat for the plunger valve 20 which is ada ted to be maintained in open position as s tension of the spring 21, by any suitable manual means, such as aphain -or cable 22 bore 16 in the up r sechaving a connection with'a' al Y23 or a leveror the like located on t edash-board of the vehicle, this pedal be' adapted to be locked by a spring .catch to hold the plunger in o en position. f
It will be o served from the structure thus far describedV and shown, that-when the plun er 2O is locked in open position there vwill e an uninterrupted passage-way between the passages 15 and 16, the lower por- 15 in the central or body ortion 11 being enlarged to provide a seat or the spring 'seated valve 2 This valve 25J under the tension of the sprin 26 closes the-cha `ber 27 formed therebe ovv2 with and through w the auxiliary ch fresh air is drawn. into carburetor, as will hereinafter be apparent. 29 isa needle valve for re ulati the sup ly of gasolene from e' iloat c amber o the carburetor 8, the gasolene .passing` through the passage. 17 and through the preferably ob iquely disposed ducts 30 communicating with the enlarged portion of the passage-way 15, in, the central or body section 11.
In the operation of my invention, the main carburetor 8`an`d the' ignition syst/empf the engine 7 are ad'uated for the operation; of .the e 'neint e pustoniary manner, the plun -valve 20` giened by means of thecieain 22 and1 asheretofore described,- after' vvI the 'engine is turned cver,the t'fof the' pistons I mtlun theV engine j linders 4cireating a suction davliieh, .throwl 'theinbdiiim of the intake ipe 9 and ipe 18", causes the ball valve? i;gj also raises the valve 25 a on-of the spring.
- t airthrough the portar 28 an simu taneously duid from the sucks u p the -gasolene or other r and through oat chamber of the Y the connecting pipe 14 and-.the passa e-wa 17, the `gaaolene or the like passing); roug carburete the ducts 30 andcombining or mixing with the air within the passa -way 15, and forinin a rich and thoroug Haporzed mixture w ich flows past the ll valve' 31 and own in Fig. 2, against the Athrough the passage-way 16 of the upper section12 to4 the engine cylinders, through the medium of the connecting ipe 13 and the intake pipe 9, a proper y pro ortioned charge being delivered toeach cy inder by reason of the fact that the connecting ipe 13 enters the fitake Eipe 9 at its hig est int so that the distri uton of the mixture is common to all of the cylinders.
I have found that the mixture delivered vby my auxiliary carburetor` in the aforesaidmanner is properly roportioned, and that a eiciency is o tainable therefrom, the in itia-l impulse of the engine taking place with comparative ease, an enabling the engineJV-to start milder a load which is fre quently e' where the main carburoter onl iam layed.
Shoul there a back pressure owin to misri ofthe engine, or from any ot er t e vaporized mixture which has passed through the auyilary not return thereto owin to e @ovision of the ball valve B1, wh' n er-`V force of such back pressure becomes within the lowarreduced portion o thwssage-way 16 in then per-section 12. en the c ngine assumeste normal condition of running, the 28 as released by the ma nipulation of the catch 24 which causes the plunger valve 20, under the impulse ofthe spring 21, to close the lpassage 15 the valve 2li simultaneously returning to its normal seated ition under the influence .of the spring 6, 'and closing the chamber 27 comninnica with. the air ports 28. The provision of t e' adjustment or needle valve 29 enables me tominutel re ate the supply of gasolene or other liqui delivered to the chamber lor vaporlaation so that I ma the h est eiciency wit Hi-.- lenpnauin ton oline.. Y
havedrh my invention with particular the embodiment here# in showband d` ,it is obvious that it is adaptable t0 Ghr uses, wherever an internll cpmbustion engine is em loyed, and
various changeain the details of structure may be made mfthout departing from thespirit andscopeg' my invention.
