To all when; it may concern:

Be it. that I, HOWARD C. BA1LEY, a citizen of the United States, residing in Philadelphia. Pen11sylvanis,-hzive invented certain Impmrements in Starting Devices for Enplosienjngines, of which the follpwmg is a specification.

One object @i my inventionis to provide a. device of a simple and "compact nature whereby an explosive engine, such as may. be used to pnopel motor vehicles, may be given the few preliminary rev0lut1onsneces-- ssr v to start it, with the expenditure of but relatively little physical energy on the port of the operstee.

It is further desired to provide a device of the general character above noted, which may be conveniently operated from the driver's seat of a motor vehicle and which will be automatically disconnected from the engine mechanism as soon as the engine is started. i

Another object of the invention is to provide a start ng device for an explosive en gine of such a nature that its actuating spring may be wound up by the engine itself after this has once l ne-a1 started; being automatically disconn d from the engine after the winding has proceeded to a predetermined extent.

The shove other advnntageous ends I secure as here nafter set forth, reference be-s ing had to the accompanying drawings, in

which Figure 1,. is aside elevation to some extent disgrennnstieell and partly in section, illustrsting the ss sratus comprising one form of my inven' Fig. 2, is an end elevation of a portion or the gearing employed in the apparatus shetrn in Fig. 1; Fig. 3, is a side elevation of the fly wheel and the automaticclutch carried thereby; Fig. 4, is a side elevstio venrion inw nhand operated clutch is einpioyed in p '03 of the automatic clutch; Fig. 5, is an e243 elevation of a per ion of the geek usedin ponnection with the apps- T3125 snown in Zlg. 4; Fig. 6, is a side elevatron a form of my invention in which the stszi-ing spring may be wound either i) or by engine power; Fig. 7,

bracket" a. Said. bearings and brackets serve as means of support for an extension ofthe mainsheft B of the explosion engine, which it is desired to start by my invention, and this' shaft is provided at one end with the ordinary stertlng crank!) and 'a clutch b v whereby said crank'may'be connected at wlll' tb said shaft. The fly. wheel of the-engine is indicated at b and has fixed to oneend of its hub a. plate 6 on -which are mounted three pflwls 6 limited as to their movementby pins or other M suitable forms of stops 6.

Upon the engine shaft ere mounted two sleeves C and C, the letter of which has rigidly fired to it a ratchet Wheel :5 mounted.-

upon it adjacent to the plate I) on the fly. w

eel so as tobe cesble of being engaged b the pawls b, ally extending arm 0'. A relatively heavy metallic spring D has its outer end connected to a pin 0 pro ecting from the arm a and-has its inner end connected with the sleeve C by means of a screw 0.

A gear Wheel 0 is rigidly keyed or other- It a o has fixed to it a radiwise fixed to the sleeve C and is connected;

through an intermediate ear 0 to a. gear'c' fixed on' the shaft c. This latter shaft is mounted in bearings on the bracket 0 and in a frame a, in any desired manner. The shaft 6 carries at its end a beveled inioncf meshing with the teeth of a heve gear e mount-ed upon a. suitable spindle carried on.

the frame a; this gear being provided with ratchet teeth at it's periphery and having a holding pawl e. Loosely mounted upon the shaft or spindle for this gear, is an oscillatory arm 6 connected.through a link e to a hand lever e.

With the above described arrangement of parts the oscillation of the. hand lever e on its pivot causes asimilar movement.- of the arm a and as this is provided with a pawl e which engages the ratchet teeth of the gear e, this latter is intermt-tently turned.

It will be noted, hen-ever, that when it is desiredto start the'engine, the brake mechanism is firstset. or some other means, such a holding device, is pro ided for tempo: rarily preventing the revolution of the engine shaft B. Consequently as the shaft e is turned by thc oscillat ion of the. lever c, the spring D is wound, since the-movement of 0", c" and c to the sleeve C. Since the engine shaft is held, the arm c'cannot be turned untions to the engine shaftordinarily required to cause the engine to start.

It is obvious that when the engine be comes self-actuating, its speed almost instantly rises to a point in excess of that of the ratchet wheel 0 which is turned by the spring D, even if said wheel has not already come to rest, and-in any case the speed of the engine is sufficient to cause the pawls If to move out of engagement of the ratchet wheel 0 and to be held out of such engag ment under the action of centrifugalfore'e as long as the engine operates. \Yhen, however, the engine is stopped, one or more of the pawls will fall, under the action of gravity, into engagement with the ratchet teeth, 'so that the device is again ready to be started.

The device forming the subject of my invention is usually employed in the starting of explosion engines used in motor vehicles and under these conditionsthe operating lever e is placed adjacent to the drivers seat. As a consequence, the engine may be more easil started than with the well known cran although as illustrated in Fig. '1 this is usually rovlded for use in emergencies. Inasmuc as the work of winding the spring is performed at a relatively low rate, it will If desired, I may arrange the various parts as illustrated in Figs. 4 and 5, in which case the gear c may be omitted, while the gear 0 is mounted upon a sleeve C carrying a plate a". This latter plate is connected through a. pin 0 with the outer end of the. spring D, while the inner end of this latter is connected through a sleeve C with the. movable member I) of a clutch. The other member I) of the clutch is rigidly fixed to the fiy wheel I), while a lever f pivoted to any suitable support, is connected to the movable clutch member which, by means of 'a hand bar f, may be shifted into and out of engagement with the other clutch member. The intermediate bearing a not onlv its outer ends so as to fit into an annular member on the fly whcel.- In this case, I

I provide a brake b for holding the fly wheel said shaft is transmitted through the gears fromrcvolution during the time in which that when the engine is operating under normal conditions. this brakei-s released and the clutch member 11 is held away from the clutch member b by means of the spring a.

When it is desired to start the cngine', the hand rod f is moved so as to throw the two clutch members 7' and 1) into engagement and the brake. shoe fis applied to' the fly wheel. The spring is thenwound as previously described, and in order to give-the engine the few preliminary revolutions necessary, the brake b" is suddenly released, when the unwinding of the spring turns the lly wheel and through it revolves the main.

shaft of the engine. Assoon as this is driven by its own power, the increased speed of the ily wheel and of the clutch member 6 causes the clutch member b? to be moved outward so that said parts are automatically dis con-- nected; the spring a" serving to retain the member b" in its disconnected position.-

In Figs. 6, T, and S, niy device is illustrated as so arranged that the spring D may,wl-ien desired, be wound by hand or may be connected to the engine after this has been started, so that it performs the work of winding said spring. In such cascthe shaft 4 has fixed to it another car wheel 9 and this meshes with'a gear 9 fixed to a movable clutch member 9 loose-on the engine shaft. The second member g of this clutch is fixed to the shaft B and the parts are so arranged that the hand barf may, througha lever f=, cause the movable clutch member g* to be coupled to the engine shaft of the clutch member g. Underthesc conditions it -is obvious that the winding shaft, 0. will be driven from the engine shaft and will consequently wind the spring D. In order that such winding may not proceed beyond a predetermined point, I provide a bell crank lever II having one arm 7: so arranged as to be acted on by one of the convolutions of thes ring D; its other arm being connected t1rough the hand bar f to thelcver f.

rio

\Yith this arrangement, when the spring D is wound to a predetermined point, it causes the turning of the lever if upon its pivot. and

such a movementof the hand bar as will then In the latter case, the sleeve C has extended through it a shaft section B carrying adjacent to the fly wheel I), a plate i connected to the outer end of the spring D by means of a pin 0 This plate, as shown in Fig. 8, has

groove in the clutch member a, and thereby mounted upon it a number of swinging fingel-s 2' each provided with a stop *1 whereby their. revolution is prevented beyond a cert ain oint. Upon the adjacent face of the fly w eel b, I mount a progtecting stud i and 5 it is obvious that when t engaged by one of the ngers iso that ower .is transmitted from thespring to t e iiy wheel through said finger and its stop .13.

VFhen, however, the en ine is moved b its own power, the fingeis t are either hel out of the way of the stop if by gravity, or, as shown in Fig. 8, turned over by it sees to rest against the stops '1',- out of the way.

Then however, the engine is stopped and the plate i again turned underthe action of the s ring 1), when this begins to be wound, the y wheel, through saidstud, is again cou led to the s id spring as before de 29 scri ed; In winding the spring by hand, I may enrploy, if desired, a bralre'shoe' I) operative on thefiy wheel, and when such win 'ng is done b means of the engine, a brake I) is ap- 5 plied to the piste 'i so as to hold this from turning indep endentl of the fly wheel. The

brake shoe b may see be used in'conjunctron with my ivmding lever attachment 1ndependently or the automatic wlndn systern, for the driver may throw onsaid rakeshoe while the engine is running and wind up the spring throu h the medium of the hand lever, thus holding said spring in condition for instant starting of the engine after 5 its next stop.

In starting high power en ines in which there is reat compression to e overcome in giving 1; e few prelmnnary revolutions, I may use a series or compression relief cocks 40 operative from the driver's seat so as to be instantlyclosed onthe first series of explosions of the engine.
