To all whom it may concern: o

Be it known that LYGLYD .TsCoLEM-AN, a citizen of the'Unitcd States, residing at thc borough of Manhattan, city of New York, in the county of New York and -State of New York, have.invented certain new and useful Improvements in Automatic Engine-Starters, of which the following is a specification, reference being had therein to the accompanying drawings, forming a part thereof. Y I.

My invention relates to 'starting means for engines not soif-starting, such-as explosion engiires, and means embodying my invention are particularly adapted for use on engines of automobiles by reason of thefrequent necessity in the use of automobiles for the performance of the starting operation.l i 'Y My invention has for its objects simplicity Ioi construction, durability, reliability in operatiomand the realization of other advantages which 4will appear from ,the following specification.

My invention `relates to starting means whereby a power-storing device is connected `with the engine to perform the operation of starting" the engine, also to releasing means whereby the centrifugal engaging device is disengaged .o r released fromhthe condition whereby it effects the connect-ion of the engine and the power'- storing device for the performance'of the winding or power-storing operation.,y My invention also relates to the general construction and arrangement of parts andl to means for manually storing power in' the power-storing device and forl turning the engine independently of the power-storingdevice. I will-now describe the construction embodying my invention illustrated in the accompanying drawings and will thereafter point out my invention in claims. Figure l is a vertical longitudinal: central section vof the starter.' Fig. 2 is a rear elevation-of' the same, 4partly broken away .to show the interior construction. Fig.A 3 is a transverse vertical section taken 'on a plane indicated by the line 3-3, in Fig. 1, and partly broken away; Fig. 3a is a detail end of one,` of tl'e pawls engaging the ratchet on the-sHring-carrying sleeve'.

and connected'parts. Fig. 5 is a front elevation o fthe! starter, with th cap or end partloi theycasing Vremoved and other parts broken away. Fig. 6 'is a near elevation of the releasing'lever.' Fig. 7 is afveiticalaxial section of the same. Fig. Suis a reanelevationfof the pinion connected to the releasing lever. end elevation of the same. Fig. lO'is a rear elevation of the spring connecting the lever and pinion.Y Fig.-11 is a transverse axial section of the lever and pinion, assembled. Fig'. 12 is a front elevation of the non-rotative diskl for'uctnating the releasing lever. Fig. 13 is a part axialrsectirm and part elevation of the same. Figs.

Fig. 9 is an.

14vand 15 are respectively an axial section and a front screw-threaded sleeve which actuates Fig. 16 is a horizontal central sec-y elevation of the tion ofthe non-rotative disk, screw-threaded sleeve4 and adjacent parts. Fig. 17 is an elevation partly in section of the combined starting and windingcrank.

The engine in connection with which the starteris to be used is not shown in the drawings otherwise than by the illustration in Fig. l of the end of its shaft 5, this shaft being coupled to the starter-shaft c by a coupling or clutch device shown as a collar 6 on the engine-shaft recessed to receive projections from the end collar 9 on the starter-shaft c.

The direction of rotation of the engine is indicated by the arrows x. The rotative force to start the engine originates at 4the coil spring a, which is secured' at its outer end to a stationary casing or inner end to the spring-carrying or outer sleeve e, this outer sleeve being fitted to rotate upon an inner *sleeve n which, with an intermediate bushing, is fitted to rotate upon the starter shat c. The outer sleeve e has, ratchet-teeth formed at its inner end, and a rotative part or internal gear and external ratchet f is tted to rotate on the outer-peripheries of ratchet-teeth and is connected to the outer.sleeve by a plurality of spring pawlsh (see Figs. 3 and 3a), of which three are shown,

-each pawl being fitted to slide radially in V-shaped grooves formed in the rotative part f and being' yieldingly thrust inward by a spring h/ e so as tol impart 'movement from the springcarrying outersleeve c to the rotative'part f in the direction of krotation of the power-springin its starting orpower-applying operation and to impart movement from the rotative part f to the spring'carrying sleeve e in thcreverse direction and engaging the drum d and at its during the spring-winding or power-storing operation.

The function of this pawl and ratchet connection is to prevent the momentum of the parts v spring beyonditsy unwound condition at the conclusion of the starting or power-applying operation in the eventv ofthe complete unwinding of the spring.

Planet pinions i and planet gear-wheels m, each ,wheel and p'inion beingsuitably securedtogether, are '.tted to'rotate on studs t" projecting from a brake-disk g, this brake-diskhaving a rear outer iange, the outer periphery of` which is fitted to rotate in a bearing formed by a stationary flanged ring g of the casing the end of which bears against the rear end plate g2 of the casing, and this brake-disk providing a bearing at its 'inner periphery for the rear end oi the inner sleeve n. A brake-band j enters a V-'shaped peripheral groove in the brake-disk g and very nearly encircles the brakedisk (see Fig. 2) and is secured at one end by a screw jz to the stationary ring g and is 'connected at its other4 end by a chain j to the boss oi a pivoted lever c, this from carrying the A' and Ariphery see Figj 12), the stationary arms projecting .A

Theioscillatingmovement of the lever 14 relatively fromafront-bearing-blO'Ck--7 BeCllIQ-ffb-ille grito-the cup p causes a partial rotation of a pinion 15 (see Fig. 16).. By' reason 0f the-acttllt f which is mounted concentrically with the axis of the nearly reached the'outer limit of their movement and the winding operation' is about to be discontinued. 1ment for the action of .the spring, Arroscillating lever '14 is carried by'the cup p, being pin :21% projecting *from the cup'p (see Fig. 4'). 4The .movement of the non-rotative plate 3 outward or tosequent orbital movement of the oscillating lever 14,

' tactwi,th a cam-projection 3 on the approaching face groove Ais formed on the' advance radial edge and on the peripheral edge of the non-rotative plate,

. -internal ratchet-bar 22, which is carried by a ring 22,

sleeve'2 is non-rotative', it is 'longf tudinally asthe power-spring linwinjds ir-.is -wou'ndg A and during the winding movement it is moved forward l and pushestheplate s forwardmward the 'Cup'pg the plate 3'being at times yieldingly pressed rearward and rthis oscillating lever 14 carries a cam-roller 12.011 'one arm thereof, this cam-roller'normally 'projecting 1n -tlie path of the non-rotative plate 3. The oscillatjing lever 14 is yieldingly heldA in such position by a.

'cam-roller will usually come-in contact with the-face 'of this' cam-projection, and as the roller is yieldingly sufficiently to mount and rollin byspring fingers 11,..se c'ured tothecasing drum d (see Fig. 5) and entering pockets 11". in the plate-3 .(see Figs 12). Asshownin Fig.;1, the sleeveand plate have fittedto' oseillate -upon a'pin 13 projecting therefrom,

helical4 extension spring`- 214,' secured at vone end to av lug l'irojecting from -the cup p .and secured at the other end to the lever 14 and holding the lever against a stopward the cup p and the rotation of the cup p and conbrings the eanf=ro`ller 12 on the oscillating lever inconof the non-rotative plate 3. Initially the face of thea held axially by-a spring l2"I located between the roller and the lever 14, the roller will b e pressed toward the lever until its orbital movement has carried it beyond the cam-projection 3 and willi'then springtoward the -tion it will beadvanced in stich position as to effectively engage therewith. I 'To further assure an effective engagement of the earn-roller 12 and the cani-projection 3, aflange is formed upon the roller and a counterpart and when in the roller next encounters the cam-projection, this flange and grmve will eng "c Vso as to effectively prevntthe roller from slipping off the cam-projection.

3 will be first'abac'kward and inward swingingmovement and then-a backward and outward swinging movement until the roller 1-2 has been-moved outward contact with the peripheral ledge of the cam-projection and thereafterY the rotatie of the cup p will not cause. the further movement tif the oscillating lever 14 relatively to the lcup 7i.; As. thelever 14-is thus oscillated, .a"s1' ring A pawl 14", which is carried on an obliquely arranged short arm of the lever, will eng "e with an arc-shaped this ring being fitted to oseillate on the'front bearingbleek 7 between stops 22c'and 22.d on the casing'and `yieldingly held against the front stop 22 by a spring 22. This ongzgement will introduce a frictional resistance such as will be effective in overcoming the momentum of the parts after the centrifugal pawls have been released.

nection therewith, this yielding effected by a helical torsion spring 15b-(see Fig'. 10) which is located between the stud 13 and the hub of the' lever 1'4 and engages at one end with 'the' pinion lland at thejother end with the lever 14 (see Fig. 11). The extent of -this yieldingr movement is controlled 75 by a projection 15l on the pinion engaging-a projec -tion 14" o n the lever with a slight freedom of move- .lever 14'on the pin 1 3 Aand has-a. slightly yielding conconriection being Thisj spring yields .when the lever is actuated by the cani-projection 3," on the non-rotative plate 3 and remains-under torsion 80 so long as thelever is actuated 'by the carrito perform the releasingoperation, but exerts-its resilient force at the conclusion of such forcible operation to effectivelyY complete the withdrawal pawls clear of engaging positions. S5

of th'e centrifugal The pinion 15 meshesl with geanteetli formed upon a portinfof the periphery of a disk 16 of 'a thrust-part including this disk 16 and anannular releasing plate 18 located .inside the cup, being connected by projections 17 extending .forward 90 the disktl and plate 18 ff'rom the disk 16 through arc-shaped slots formed' in the web o f thevcup pand ofsuffieient length to accom- I modate the part rotative part relatively to the clip p, and' theplate* 18 is secured to the projections .17- at the front end thereof, A -as bythe screws shown. ried by the thrust-part, their outer ends 'being shown movement yof the thrust- Cam-pins 17 are' also car- `secured in the projections 17 bythe same screws that secure the disk 16 thereto, and these Ycam-pins extend inward freely throng' plate so ,that when it next approaches the cam-projee p wiae'sloa nin the hub grooves formed in the reduced front end 4of the inn-er sleeve 'As the cup p is secured upon the -i `r sleeve n, the partly rotative .movement of the disk 16,. resulting -from its actuation'by the pinion 15, causes the 'cam-pins 17a to move in the cam-grooves in the nersleeve n, and thereby -the thrust-part is projected forward ortoward the block t which carries the centrifugal pawls u. This movement is imparted' to releasing pins 19, .'Whicll. are vannularly. grooved so 'as The movement hf the lever 14 resrilting from contact to A vof its cam-roller 12 with the end of the cam-projection l be engaged in an inner annular groove inthe releasing'plate -1'8, and which are fitted to slide in bear-l ings formed in the block't, and pass through perforations in the centrifugal pawls u. The releasing pins 19 contain cylindrical portions-of diterentdiameters 115 united `by truste-conical 'thrust` forward these"frusto-conical portions are-thrust forward intocqntact with' the walls of the perforations Ain the centrifugal pawls pawls inward out of engaging positions. The annu- .larly grooved engagement of the releasing pins 19 and the releasing plate 18 permits the pins 1 '9 to revolve orbitally with the starter-shaft c and also to rotate on their own axes when not restrained by frictional contact with their respective centrifugal' pawls, so as to present different portions of their peripheries at dif- 4ferent operations -of wedgingl the centrifugal' pawls inward, and this annularlylgrooved engagement alsoA permits the releasing pla the cup p and inner sleeve a, butneyertheless assures portions and as th'ey are 18 to rotate freely with positive actuation of the releasing pins by the releasing plate both in the engaging and releasing movements of the releasing pins. The result of this release or disengagement of the-` centrifugal pawls u is that vthe starter-shaft ceases to imparti'r'otati've movement -zto the cup p'. The retractive action of the power- "spring willthen b e exertedduring. the brief interval.

U-r which will elapse before the engagement of one of the stop-pawls f witha tootli on the rotative -part f, but any backward rotation of the cup p resulting therefrom will merely cause the arc-shaped Ainternal ratchet-bar2`2 to be moved backward by engagement therewith of the pawl'14 on the lever 14, and such movement will bewithin the limit of the movement oi-sucli-bar between the stops 22" and` 22d. The resulting positionfofV parts is shownin Fig. 5; the cen'- trifugal pawls u being inward out of'engaging position andthe pawl 14 on the releasing lever 14 in engagement with the ratchet-bar 22.v 'The power-spring a is now 'fully wound and the starter readyto perform a.

starting'o'peration So long-as the brake-'disk g is locke'dby its-brake-band j the power-springe will and the'brake-dis'k g and the'linner sleeve n, the rota- -A tive movement f of the partf' being imparted 'through- 'i sleeve nrwithout rotation'ofthe planet-pinions 'and planet-'wheels on--their ownagres. Thus the inner the planet-piniorls i and planet-wheelsm to the inner sleeve n and the cup p carried therebywill be rotated in'thesame direction in which they were rotated when winding the-spring, and the pawl A14a and the spring.22 w.ill carry the ratchet-bar 22 into contact with its frontstop 22 !and' thpawl 14a will thereafter click overthe'teethof the lratchet-bar until it moves clear thereof andthe cam-roller 12 on the releasing-` lever 14 will be carried forward in its track' on the periphery of the non-rotativeplate 3 'until it has moved clear -of vthe cam-projections@ and will then be swung l by its spring 2li-hachs the-disengaged position shown in'Figs -4'and 1,.itbeing Aremembered'that the un- 4 5-l ing the threaded non-rtative'sleeve 2 to'bewithdrawn winding of thepower-spring is at :the same time causand thatthe non-rotative plate 3 is being caused to follow this movement by its spring-fingerslll a vEhe-'returnof` the'lever 14 to disengaged position- -will cause a reversepartial rotation of the `pinion 15 l and of-.the disk- '16 engaged therewith and, immensequence of .this movement, the thrust-partcomprising` the disk 16. and the annular releasing plate 18 will be withdrawn -and will withdraw the'releasingpins 19,. all. of these-'parts being returned to the position shown in Fig. 1and .thereby 'the centrifugal pawls u will .be released.. With the centrifugal 1pawls thus `released;- these pawlsarein condition-te be m'ovellinv 'engage'- ment by centrifugal force and to cause the rewinding ofthe power-spring a as soon as the engine attains'` the predetermined ,speed 'selected as suitable forl the winding operation. It will be noted thata comparatively-smaliunwinding. movement I,elf the powerspring willrelease the `centrifugal pawls and' thus put thestarter in condition to be rewondand therefore reWinding-iiviil occur after every material movement of the spring, so that the spring'will be reoperating sleeve 29 in forward position. 'an engine-starting operation under power is desired, -the' shaft-operating sleeve may be'withdrawn'and then unwinding stored to fully wound condition whether or not its full force has been exerted in the starting operation.

For the purpose of initially Winding the power-spring and of rewinding it in the unusual-event of an operation of the engine through suchashort interval of time that the spring ,has not been wound by the engine, or of va'failure to start the lengine by the spring, such as may result from a lack ofproper adjustment or failure of operation of other parts, as, f or example, of the sparking device, provide a combined winding and shaftperating crank 26, the end of the hub of which has diametrically opposit'e recesses 27 for engaging with a cross-bar 28 secured on the outer'end of vthe cup p, for the purpose of winding the spring. The, crank also end of the starter-shaft to directly operate the startershaft. and engine-shafts,`and this sliding sleeve is controlled by a spring-pin 31 so that it can be pushed forward ntooperative position, as shown in Fig. 17, or withdrawn from-such operative position, and will be held in either position by thelspring-pin 31. If, for

example, .it is ldesired to turn the engine-shaft, as for hasasliding-shaft-opcrating sleeve 29l shaped at its -innerend so as toengage the cross-pin-30 at the front inspection, adjustment or lubricationof parts, the

crank is used-in the position shown', with the shaft- If-,however,

the crank will engage the cross-bar `of the cup and will' wind thespring, this winding of the spring being accomplshed through the reducing gearing and `requir v ing comparatively little effort, 'and eHecting the automatic operation of the releasing mechanism when' the spring is fully wound,
