ENGINE-STARTER.

State of Nen' York, have invented n certain newand uselul Improvement in Engine-Starters, oi which thel folloiving is a specification, reference being had therein.

' to the accompanying drawings, forming. part thereof.

My invention relates generally to starting devices for.- in tcrnal combustion engines, more particularly engines such as are used on automobiles 'or motor boats, and has 'for its objects simplicity of construction, and convenicnce, simplicity and efficiency of operation.

I provide a manually controllable valve for admitting compressed air from a reservoir to the air intake conduit of the carburetor, the communication of the air intake ol the carburetor with the outer air being closed at this time by a valve provided for the purpose, so that the air' iindcr pressure from the reservoir passes through the carburetor, vaporizing' the suiliciently volatile liquid fuel supplied to the carbureter. The combustible mix- ,ture thence passes to the working cylinders .of the engine and into and through all of the cylinders until the former and more or less iucombustiblecontents o the cylinders are driven out and replaced by the combusti ble mixture or priming, inlets to and outlets from the 'cylinders being opened for this purpose by manually controllable means. Means are provided for preventing the operation of the' sparking devices or ignition devices during the time that 'the cylinders are receiving their priming. In'the preferred form of my invention, ior ordinary running, a fuel isused which islcss volatile than could bo efficiently used for starting or'ior running .while the carburetor is yet cold. In this preferred construction means. are provided for 'supplying the car- 'bureter with a more -volntile f u el Ior starting and for ru'nning until the less volatile fuel can be-vaporizedbythe carhureter, such as is the subject of4 my prior ap'plication, Ser-inl Number 349,277, Bled. December 24, 1906.

A single-unidirectional movement of a manually operable part or lever 4prevents the operation ol tbe sparking devices, Iorces'open the inlet and exhaust valves, conf' nects the more volatile fuel to be used for vaporization and cuts offthe supply of lessvolatile .or ordinary runcauses the closing of or continues the closed conditionei ning fuel, opcnsthc compressed'lir supply valve', and

The engine then starts by the ignition of thc priming charge and continues to run by drawing atmospheric air through the carburetor in the usual manner.

My invention includes means for introducing priming 'of combustible mixture into all of theengine cylinders concurrently and fOrpassing-such priming through the cylinders until tlie cylinders have become filled with the priming and the previous contents of the cylinders have been substantially displaced:

My invention also includes mearis for elccting'sucli priming from a selected one of a plurality of sources of volatile fuel, whereby the cylinders may be primed for the starting operation with a hipi grade (ucl and may be run until the carbureter is suiciently heated on such high grade fuel and muy be thereafter run on ordinary or low grade fuel. -4

4 My invention also includes means for preventing the operation of the ignition devices of the engins during the time that the engine is receiving its priming.

, invention also includes various improvements in the construction and combination of parts, and has other-objects and advantageous features, which will appear from tbe following description of the means srning my invention, with a diagrammatic illustration of the' sparking circuits. Fig. 2 is s. transverse vertical section taken centrally through one of the cylinders, on a plane indicated by the line 2-2, Fig. 1. Fig. 3 isan enlarged detail plan oi a portion of the longitudinally slidable bar with a valve-opening cam-block thereon. Fig. 4 is an enlarged vcitical transverse section oi the .carburetor on a plane indicated by the line 4 4, Fig, 5.'

Fig. 5 is an enlarged vertical longitudinal scctio of the carburetor, taken On apcntral plane, as indicated by the line 5 5, Fig. 4. Fig. 6 is a side elevation, partly in section, of sn internal combustion engine including sn embodiment O'f my invention in modified form.

The engine shown is a four-cycle [our cylinder engine of usual construction, the cylinders 1 0, as ordinarily,

being srranged=in pairs, the exhaust outlets for the respectivo cylinders appearing t 11 in Fig. 1, the

exhaust manifold piping 12 (see Fig. 2) being removed for cleamcss. The cylinders receive the'. supply el combustible mixture through inlet manifold pipes 1,3 connedtcd h'y x11-connector 14 with a common supply pipe l5 and each opening into an inletchambcr 16 lcommon to a pair of cylinders (Figs. l and 2). I Esch IUS cylinder has an exhaust-valve 17 carried by l'stem or opemtingv-md 18, and also has sninlet valve lQ'cnrricd by a stem or operating-rod 20. The exhaust and inlet valves are mechanically operated irl proper sequence -by a usual com-shaft 21 carrying valve-operating cams i 22 to engage with the lower' ends ol the valve stems to lift the valves against the tension ol usual strong valvecoating thrust-springs 23 coiled about 'the vulve-stems and abutting against usual collars 24 thereon. The

lj-enginc has a main-shalt 'or crank-shaft 25 to which are l connected pitmcn or piston-rods 26 -carrying pistons j 27 working in the cylinders 10. Firing or ignition 'takes placolrom usual' spark plugs 28 from which spark-circuit conductors 29 lead to respective segments of a distributor whose. ornmon'contact terminal 3D is connected by a com mon'conductor 31 to one terminal ol the secondary winding32 oi a spark-coil, the other terminal o l' the spark-coil scconclflrjr 'boing shown as grounded at 33. thus completing thecircuit. Current p for thcspsrk-coil is supplied by abnttory 34, the circuit 291 from which may be traced by way ol conductor 35 lhroughthe primary 3B ol the spark-coil, interruptor or buzzer 37., conductor 38, timer 39, conductor 4D, un

Thel timer, distributor, sparir- 25 coil, battery nndnll circuits are shown diagrammatically; and the distributor and timer are shown as operativily connectedtogether arid electrically insulated from eachother as usual. Everything above pep V ticularly described, excepting alone the ci rcuit-breaker' S0 'or cut-out mentioned, i`s usual and ordinary construction,;liut should be noted so us to properly understand -my invention in its relation to the parts described.

.-Ths combustible mixture for the -engine is supplied by l carhurctorol the construction shown, described 85 and clniincd in my above mentioned prior application. This carburetor has duplicate Iucl-rescrvoirs or floatchsmbors 42 and 43, through which posses a common air-conduit 44 which is continuous at its delivery oud with the delivery or engine supply pipe 15 and is cou- 40 tinuous nt its intake end with an intake conduit 45:

In 'operation great-er'prcssurc'at the intake end causes l current of air to para through theek-conduit in the4 direction indicated by "arrows, 'such pressure b'eing caused, when the engine is running, by Athe suction or 45 low pressure produced by the engine. The two inde-l pendent [lont-chambers are provided for containing volatile liquid lucls of different grades orkinds. For

example, the chamber 42 muy' contain s. grade or kind i of uel suitable I'or ordinary runningconditions auch .50 as exist alter the carburetor has become warmed hyp. short period ol the running 'of the engine.. This volstil'e liquid may be low grade gasole'ns, of 68 to 76 Baum, or kerosene, or alcohol. -The chamber 43 m'sy contain s grade or kind oi u'el 'suitable for starb l'. ing the engine, such us high grade gasoleue, preferably-` d about BBBsLum, or benzin.

The'carbu'i'eter is provided `with an inwardly opening auxiliary air-inletvalve'dnormally retained upon 4its seat by a spring 69.

According to m'y invention, preparatory to storting the engine, all of the cylinders are to be filled with combustible mixture. To this endmeans are provided for blowing the combustible mixture through all of the cylinders concurrently, such means including l sourcel ol compressed air shown satin sir receiver or sir storage reservoir 70.4 o lar. as'the present invention is concerned, the supply of airheld under compressiouiri tlc-Jeacrvoir 'IQ may be replenished in any convenient manner. .For use in thus replenishing the air the reservoir is provided with a plug or coupling part '71 liaving therein .an inwardly nripening check, valveJZl- To produce a combustible mixture for starting the engine,

the compressed air ,from the reservoir is passedv through the carburetor, and to assure thst a combustible mix'-, ture will be then produced niesus are provided for ascuring that the higher grade of fuel will it that time b'e supplied tov the carburetor. For passing 'air through the carburetor 'an air-conduit 73 leads from the r`eservoir 70 and opens into s passage 74 which communi- Cates, through a manually 'operable oir controlling valve 75, with. a passage 76 which opens into the airin'tako pipe 45 ol the carbureter. The air-controlling valve 15 could be ol any preferred construction but is shown as of the puppet type 'cn'djls opening towards the air reservoir. This'valve has an actuating stem extending rearwardly t'the atmosphere through sn' ordinary packing gland as shown, the stern terminating ih a head by which the vilvs may be actuated. This valve is held upon itl b'y the prsure o! the 'air in the nir reservoir', aixd'il additionally retained upon its seat and made to quichly-closs by l valve-closing thrust spring shown as coiled about the vslvecte'm and acting upon the head of the valve-stom.

The lli1r-iuutlre pipe 46 i! provided as usual with an air inlet opening 77but in sdditxon thereto s vulve is provided lor controlling this slr' inlet opening, this valve beim dsosrn as an opening check-valve and in pressed lightly towards its seat by a thin spring as sho'wn, thus presenting no appreciable obstacle to the ingress o! air in the operation of the engine, but

closing unrler pressure o( the air from the reservoir to prevent the escape of this air to the atmosphere and to compel this air to pass through the carbureter. As tho air from the sir reservoir passes through the carbureter it readily vaporizes the high grado'iuel which is provided lor starting and forms s. combustible mixture which is passed into'the cngine`c`ylinders and milde' to displace their former contents until the cylinders becomo lillcd with the combustible mixture.

To allow the cylinders to till with combustible mixture, means are provided for forcing open and holding open all ol the cylinder inlet valves 19 end also at the sometime allot the exhaust vslveii 1.7 until the cylin ders are thua'llled. Thus when the cylinder inlet and exhaust vulves are open and the air controlling valve is open, compressed air will be b lown rom the-air reservoir through the carburetor wherein .it will be carhureted to en explosive mixture, which will be 'blown through the cylinders, displacing their former contents and filling the cylinders with combustible mixture. When'the cylinders ha've become lillcd `with combustible mixture the inlet and exhausthvalves and the air controlling valve are allowed to close, utter4 --which the engine is made to startl by'igniting the mixturc in the cylinders in the proper order orsequence.

The means shown ,lor holding opeh the inlet and exhaust valves comprise valve-opening cam-blocks- 79 carried hy s longitudinally slidahle bar guided in hearings 8l on the engine llame. These' cambloeks have sa shown a sloping or wedge-shaped portion for engaging beneath thevalve-stcrn collars 24 to raise the valves'. The bar BO'has elongated openings or slots to permit the valve stems 13 and 20 to pass through the bar without intcrlcring with the sliding movcmentof the bar, and a valve-lifting cam-block 79 is located at each nido laterally of cach' ol auch slots (ses Fig. 3). The cams or wedges 7S) are shown as normally located in rear ol the valve stems, necessitating that the sliding har 80 be moved forward to effect an opening of the engine vulves.'l The liar 80 is shown ns having pi'vl otallconnection at Aits rear end with an intermediate lever 82 which is pivutally supported by a stationary part ol th'e engine as shown. held alrite rearward position by a thrust-spring 83 actning between theintormediate lever 82 andthe engine Iranie. -The bsr 8.0 may be actuated 'at will, to cause tho'calns 79 to open the enginevalves, by a pedal or foot-lever 8 4 connected to the intermediate lever 82 by a linlr or lconnecting rod B5. when the pedal 84 is pressed the cams 75l Awill beactuated against the tension of the cnm-'bur-restoring spring 83 to lorca open all of the closed inlet and exhaust yalves 17 and 1.9. against the tension of the valve-closing' springs 23, and

"when the pedal is released all of the inletand exhaust valves not held'open by the valve-operating cam: 22 will beclosed by their valve-closing' springs. "The intermediate lever 82 extends'downward beyond its connection .with the cxm-op'eratingbar 60 to engage with tbs head or outer erid oi the vslvefstem oi the air-J controlling valvo 76 to hold this valve open while the inlet andhxbxust .valvesof the engine are held open.

.The bar 80 is normally When th pedal is released the air-controlling volvo will be closed by its spring and. by the pressure ol aix' in tho reservoir. To form s proper combustible mixture for starting the engine, means are,provided lor automatically supplying the higher grade luel' or starting iuel and for cutting off the lower grade iuelor ordinary running fuel. Such means comprise e. valve-actuating pin 86 carried by the slidable bar 80 at the rear of and in alinementl with the upper arm of the-hell-cranlc lever 61.' When the bar 8O is moved forwardly to open the enginewalves the pin 86 engages with the bell-crank lever to push the upperarm thereof forward, thereby,'through connections .containing low grade or ordinary' running full, and its nozzle, is seen in Figs. 2, 4 and 5. lt is usually desirable that the engine shrill not only be given its initial or starting movement with high grade fuel, but that it shall continue-to use the high grade fuel until the care bureter shall have becomo-suiliciently warned to attisactorily vaporize the ordinary running fuel. Thcrofore, the nozzle-controlling valve 56 is not arranged to be operated in its opposite direction oi rotation by the return movement of the bar S0, the pin 86 `then merely moving away from the bell-crank 61, as shown in Fig. 1, leaving the nozzle-'controlling valve the position seen in Fig. 5. After a short period of running oltho engine thenozzle-controlling valve may be independently restored to its former position, to supply the ordi-- nary running fuel, by drawing backward the handle G3. Means ere'providcd for preventing ignition while theV cylinders are being filled with combustible mixture. Such means us shown comprises a cutrout or circuit breaker for automatically opening the battery circuit. The battry circuit conductor .40 ls connected to a contact spring o'r movable terminal 87 shown as c'arric-l by but electrically insulated from a brise-plate 88 o which is connected thel buttery circuit conductor L The plate 88 carries an adjustable stationary contact tonni 'nal 89 for coperating with the movable terminal 87.

The foot-lever is shown as extended below its lulcrurn lp'ivot and provided with an insulating tip which normallyfengages the spring Contact terminal El? to lrolrl il; in contact with -the stationary contact termnal't) undn thus to preserve the continuity ol the battery circuit. However, when the pedal is pressed forward to xictuate the above described devices for blowing a combustible mixture through the cylinders, the contact spring 87' is released and opens the battery circuit, lenergizingl the spark-coil and preventing ignition taking place until thebattery circuit is restahlished by the release of the pedal.

It is to be noted that allot the abovemamed inc i- I i ldentls lof operation should take place their'proper sequence.' For example', it is obvious that sparking should be discontinued prior to the opening ol the aircontrolling valve., `n uclitis obvious that the 'sparking should not be resumed until after mohair-controlling'valve has closed, nor until after the 'inlet and e'x-V haunt valves have been re'loasodby cams 79, it il Y preferable that air-controlling 'valve should not bo opened until alter the inlet and exhaust vulves' have heen opened-nt lenst sulliciently to provide s clear nud unobstructed voy through the cylinders so that the nir may pass reely through the carbureter to produce su eflcient vaporizution. As shown in the drawings (Fig. l), when the loot-lever is depressed the c'ohlactspring 87 will be released and will open the battery circuit along' with the initial vulve-opening movement ol the bar 80 and previously to the engagement of the,

' lever 82 with the stern ol the aincontroliing 'vlve 75 to open auch valve. .As shown in the drawing-s, the inlet and exhaust valves will have substantially completed their opening movement prior to the' sctuntion of tho l air-controlling valve 75; The nozzlerontroliing4 valve l5 56 ivill be nctuuted, tosupply storting fuel to thocarbureter, along with tlie vulve-'opening movement ol' 4the bar 80. -Wllen the pednl is released the spring 83 'acts upon lire lever 82, lirst, incidentally. to release und pennit the closure ol the air-'controlli-.i'g valv'e 7.5, wond |ast,just alter the inlet and exhaust valves have been relensed hy the ca'ms 79. to depress the contact spring 87 and rcstorethe battery circuit.

To start the engine tin.l perlnl is simply pressed down and held for n few moments and then released. Ignition will then toko place in whichever cylinder sparkying occurs,according ln the operativo position of the distributor or sprk-controllel 39. Should the operative .position he such 'tlmt sperking'does-not occur, then .'spnrking may be caused to occur by manigulation ol' the spark-controller in the usual n'mnner ol spark adjustment. lter the linut ignition has loccurred, und. en initial storting movement thereby given, the charges fin the other cylinders will be tired successively in their l'aropr order, the engine then continuing to run in th ordinary manner by dmwing nir through the carburetor mul atmospheric nininlet 77. Alter a short period of running: :md consequent vmnnig of the cnrbureter, nrdinury running fuel may be substituted for the starting luvl by operoting the nozzle-controlling handle 63 nsuhove described. VIn the modilcatiun illustrated in Fig. G, the inven- 4t'in is showrin ils sin1plcst form. 'The constructionnud operation ol corresponding parts through ut lr'e substantially identical with those just described. The sparking devices are omittedbecausel identical with irlml. is showr. in Fig. l. The only'substantnl difference in the modified construction from that just described is that in` place of the duplex carbureter am ordinary carburetor 90 is employed. This also-,f course eliminates the mechanism lor effecting a change' Imm one gmdc or kind ol fuel used to another grade or kind.
