ENGINE-STARTER.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed July 18,1904. Serial No. 216.912.

To all whom, it may concern.-

.Be it known that I, Cmmr: J. COLEMAN, a

'of'the United States, residing at 'Rockaway, in'the county of Morris and State sity in theuse of automobiles'for the per formance of the starting operation.

My invention has for its objects simplicity of construction, durability, reliability in op eration, and the realizationof other advantages which will appear from the following specification.

My invention includes improved means whereby a power-storing device is connected with the engine to v start the engine and whereby the engine is connected to the powerduced speed of the power-storing device relatively to the engine so as to minimize the load upon the engine during the power-storing operation.

My invention also includes improved means for efiecting the engagement and release of centrifugal engaging means whereby the engine is connected to the power-storing device upon the attainment of a predetermined speed of the engine and whereby an inoperative condition of the centrifugal means is effected by the power-storing device when the power-storing device is fully charged.-

My invention also includes various improvements in the construction and combination of parts generallyapplicable to power starting means and specifically combined with spring starting means.

I Wlll now describe-the construction embodying my invention illustrated in" the accompanying drawings and will thereafter point out my invention in claims.

Figure 1 1s a longitudinal vertical section of the starter. section of the same takenon a )lane indicated by the"l,ine. .2 -2 Fig; 1. ig. -3 .is,.,;a

Fig. 2 is a transverse vertical transverse vertical section on a difierent plane indicated by the line 3'3', Fig. 1, also coking to the left in Fig. 1. Fig. 4 is a detached front elevation of the clutch disk. Fig. 5 is a detached plan view of the clutchdog releasing device. Fig. 6 is a detail section showing the detent for one of the gov:

ernoi arms, taken on an oblique plane indi- .cated by the line 66, Fig. 2. Fig. 7 is a face view of the clutch-dog releasing device.

Fig. 8 is a diagrammatic view of the starting means and an explosion engine to which it 18 connected and of portions of an automobile body.

The engine 1. illustrated in outline in Fig. 8 is an explosion engine of ordinary construction, which by reason of the fact that it is hon-starting or not self-starting, requires the application of a rotative force to its main shaft 5' to initiate the rotative movement thereof and to continue such movement until the engine is self-actuated. The direction of rotation of the engine is indicated by the arrow 4. The rotative force is shown as applied through the sprocket-wheel 14 fixed on the engine shaft 5 and drivenby a chain 12 running over this sprocket-wheel and also running over the sprocketwl1eel r of the starter, thelast mentioned sprocket-wheel 1' being the engine -.connected part of the starter.

The retractive power storing device of the starter is shown as a pair of coiled or helical springs a, a, each of which is secured at its inner end to a fixed sleeve a on, the station ary shaft 0 of the starting means, and is secured at its-outer end to a drum d, this drum inclosing the springs and being carried at its rear end by a partly internally threaded hub 6, hearing at its unthreaded portion on the stationary shaft 0 and fitted to rotate thereon. The drum has at its front end a head d, also fitted to rotate on the shaft 0. shaft c'is keyed in standards 8 and 9 of the starter frame, this frame also'having a base plate 7. This drum is hereinafter referred to as a part connected .to-the spring or powerstoring device and as a springcom 1ected part and power-storingdevice-connected part. A lock-whecl l) is fitted to rotate freely u on a starting and winding sleeve f, herein a 'ter referred to as a starting and storing partwliich is fitted to rotate freely upon the senses starter shaft-c. This lock-wheel b has-square teeth which are engaged by the spring-con trolled starting-pawl I) carried by the front drum-head d, this pawl and toothed connection being hereinafter referred to as unidirectional engaging means; and these square teeth are of sufficient width to be also engaged at different portions of their width by be released to permit the helical springs 13,

connected to the lock-arm 10 and the baseplate 7 of the starter frame, to return the ock-arm 10 to locking osition, thereby ele vating the pedal. The ock-arm is limited in its unlocking movement by the engagement i 1 v of a notched stop-piece 18 thereon with a stop-pin 15, and constitutes with its toothed and connected part the locking device for the lockwheel.

The starting and winding sleeve has fixed thereon a starting ratchet-wheel g and a winding clutch-disk it. The sprocket-wheel 1*, over which runs the chain 12 connecting the starter with the engine shaft, is fitted loosely on "this sleeve between the starting ratchet-wheel and the winding clutch-disk. This sprocket-wheel r carries starting-pawls,

of which two g, g are shown, these starting 4 pawls engaging the teeth of the starting ratchet-wheel 9' during the starting operation to transmit the rotation of the starting and winding sleeve f to the. engine-connected sprocket-wheel 7. When the engine is selfactuated these starting-pawls are carried forward and are drawn outward by centrifugal force, overcoming their light springs g g and moving them clear of the starting ratchet-wheel g, so that during the-self-actu ation of the engine they. will be held by centrifugal force out of contact with the-ratchetwheel and will not rub over the teeth of the wheel, and the wear and noise which would otherwise result will thus be avoided. When, however, the engine slows down below a predetermined speed, the springs.. c, will move the pawls inward intocontact with the teeth of the starting ratchet-wheel andthey /will be in position to engage the ratchet-Wheel to receive the thrust of the-starting springs and will be held in contact therewith by their locking engagement until'relea gwd and thrown outward by the seli actuatiaid of the engine.- These starting pawls g are therefore centrifngal p a-wls which are moved by centrifugal forceout of engaging position. .They" andtheir gatche't-wheel are also unidirectional engaging means connecting the starting and winding sleeve. f with the engine-connected sprocket-Wheel 7', which engage and transmit the starting thrust from the spring-connected part to the engine-connected part.

The lock-wheel b carries planetary gears, of which three 0), i, 2', are shown, which mesh with the internal gear teeth of the s ring drum head 1), these internal ear teeth eing shown as formed upon a rin I2 tightly fitting an overhanging part of t 1e head. These planetary gears also mesh with a central pin 10m 7 on the starting and windin sleeve 7 and shown as formed on an en argement thereof. It will be noted that the lock-wheel b, which carries the planetary gears i, is fitted to rotate upon the starting and winding sleeve f between the pinion f and the starting ratchet-wheel-g and that it has a disk portion which fits loosely within the spring drum dfso as'to inclose the gears, and has an annular portion on which the square lockteeth are formed and which overhangs the starting ratchet-wheel g and'its pawls 9, thus inclosing these parts and afiording a very compact construction. I

The parts above described perform the starting 0 eration'. This operationwill now be descri ed before describing the power storing or winding mechanism and the operation whereby the springs are automatically 9 wound so as to be ready to perform the starting operation.

The thrust of the starter springs a, a, when wound, is exerted upon the spring-drum d in the direction in which the engine is to be rotated, and the lock-pawl b, byits engagement with'the lock-wheel b, prevents rotation of this spring-drum relatively to the lock-wheel I) under the thrust of the startersprings, while the lock-ar1n 10, by engagement of its tooth j with the lock-wheel b, pre- .vents rotation of the lock-wheel I) under the thrust of the. starter-springs,- and thus the starter is securely held with its sprm s wound -g'ear on the sprin -drum (1 and impart rotation to the central pinion f at the same rate of rotation as the spring-drum-the springwith its planetary gears and the starting and winding sleeve f with its central pinion, ro-

drum with its internal gear, the lock-wheel tating as a rotary unit and im arting the thrust-inf the starter-s rings to t e starting 12;,

and windin sleeve. he starting ratchet i wheel g on t 'e', sleeve 3 imparts therotativc movement. of the sleeve to the sprocketwhheeti throughflthe start'in'gy-pawls' g, and t ere ore'the sprocket-wheel r is rotated at 1 gine.

the same rate of rotation as the spring-drum and the power of the starter-springsis 'di-- aft until the engine becomes self-actuating with greater rotative force than is ap lied to 1t by the starter-springs, but when t iis con- .dition i attained the stafrting-pawls 9 will be advanced and moved outward by centrifugal force,- as above described, so that their continued movement under the operation of the engine will be altogether clear of contact with the starting ratchet-wheel 9. To prevent unwinding of the springs beyond their natural or normal set or shape, which would tend to wind them up in an opposite direction and might break springs of considerable strength, I provide a reciprocating stop-pin k fitted to move longitudinally in alug 19 of the starter-frame and in the stand-.

ard 9 thereof, and actuated by a lever mas hereinafter explained, so that it willbe pro jected rearwardly into the path of the head I of the pivot-pin of the lock-pawl b and will stop the sprin -drum by contact with such head before the springs have'become unwound beyond. their normal set; The automatic operationof this reciprocating stoppin is required so that it will not be projected into operative position until after the commencement of the final revolution which would be terminated by contact with this stop-pinshould the springs become so far unwound.

Ordinarily the release of the pedal will occur before the exhaustion of the startersprings, but should it be delayed beyond the point of exhaustion of the starter-springs, no injury could result to the mechanism by reason of the construction above-described.

The strength and capacity of the starter spring would usually be such as to allow an ample margin over the maximum work required to start the engine. l v

The winding clutch-disk h is provided with clutch-dogs, of which two 0, 0, are shown. These clutch-dogs are normally held intheir extreme outer positions, shown in Fig. 2, by light springs 0, 0, as well as by centrifugal force. Centrifugal or governor-arms are also provided, carried by the sprocket-wheel r and pivotally mounted thereon, two of.

these arms p, p, being shown, each governorarm having a weighted end and a toothed end and the governor-arms being connected by helical extensible springs p, p, tending to hold the arms in. the position shown in Fig. 2, with their toothed ends clear of the path of the clutch-dogs 0, 0. Centrifugal force will tend to move the weighted ends of the governor-arms outward and their toothed ends spring-detents s therein which normally the front standar enter depressions in the face of the sprocketwheel 7' (see Fig. 6), affording a resistance superadded .to that of the governor-springs p and holding the governor-arms until a centrifugal force is developed which will. move them quickly outward and will thereby cause a quick inward movement of their toothed ends and a positive engagement with the clutch-dogs 0, 0, of the winding clutch-disk h. This movement will'not occur until a predetermined speed of the engine, usually its full speed, has been attained, so that the work of winding the starter-springs will not have to be performed by the engine until it is fully capable of performing such operation in addition to its ordinary work. The movement of the governor-arms is limited by ordinary fixed pinsv r entering slots in the'faee of the sprocket-wheel 1.

When the winding clutch-disk his actuated by the sprocket-wheel r, the starting and winding sleeve f and the central pinion f thereon will be rotated and the planetary gears 41 will be rotated and will transmit rotation to the internal gear (1 of the spring-drum d in the opposite direction and at reduced speed, rotating the spring-drum and winding the startensprings a. the spring-drum during this winding operation diminishes the load upon the engine dur- 9 ing the winding operation, and it is to be especlally noted that this advantage of leverage to the engine during the winding opera tion is not present during the starting opera-' tion, as during that operation, as above described, the spring-drum and starting and releasing plate 25 loosely mounted upon the starter-shaft 0 'near the front end of the shaft so as to bear against the back of the front standard 9 "when in inactive position, as shown. This releasing plate t is provided with overhanging ends t, t, the inner arcshaped faces of which are adapted, when the releasing plate is moved rearward, to engage forward projections on the clutch-dogs 0 (see Fig. 4) and therebyto move the clutch-dogs inward, clear of the. toothed endsof the governor-arms p. The releasing plate t is yieldingly held against'limited rotative movement by spring-pins a a, sliding in lugs a u, (see Fig. 7), these lugs projecting rearward from 9. and having inclined faces co-acting with the inclined faces on the ends of the releasing plate t (see Figs. 5 and 7) to assist in moving the releasing plate rearward away from the front standard 9 and into position to engage the clutch-dogs. The

The reduced speed of 7 spring-pins u press the releasing plate t against a stop-pin u;

The control of the releasing plate t from the starter springs a is accomplished by means of a slide-rod e seated in a ey-way in the starter-shaft c and shaped at its rear end to engage the internal threads of the rear hub e of the spring-drum so that'it will be moved forward as the starter-springs unwind and will be moved rearward as the starter-springs are wound up.

The slide-rod e in its extreme forward position, as shown, comes in contact with and pushes forward theupper end of the stop-pin lever m, thereby causing the reciprocating stop-pin k to be projected into the position shown, in which it will come in contact with the head 6 of the pivot-pin of the lock-pawl vb so as to arrest the movement of the springdrum and starter-springs beyond the normal set of the starter-springs, thereby preventing the possibility of breaking the springs. The stop-pin k is withdrawn upon the rearward movement of the slide-rod e by the spring m bearing against the stop-pin lever m, so as not to interfere with the rotation of the springdrum in other than the final revolution thereof. The slide-rod e, as it ap roaches its extreme rearward osition or t e position corresponding to the wound condition of the starter-springs, causes the releasing plate t to he moved rearward so that its overhanging ends it, t, will engage with and move inward the clutch-dogs 0, 0. This actuation of the releasing plate is accomplished by means of an actuating spring-pin v loosely fitted in the releasing plate in position to be engaged and actuated by projections o, u, on the sliderod e. These parts are-shown with the re leasing plate in forward and disengaged position, and with the actuating spring-pin v pressed inward by the pro'ection '0 of the slide-rod e. As the slide-ro e is moved rearward during the winding of the springs, the actuating spring-pin v is projected in front of the projection 22 and thereafter contacts with the rear face of the front projection o, and the engagement of these faces projects the releasing plate rearward into engaging position, as soon as the force developed is suflicient to overcome the detent spring-pin w. The rearward movement of the releasing plate brings the arc-shaped faces of the releasing plate into engagement with the clutch-dogs 0, pressing the clutch-dogs inward and disengaging them from the toothed ends of the governor-armsp. The successive positions of one of the clutch-dogs at and after contact with an armshaped face of the re leasing plate are shown in broken lines in Fig. 7. -The function of the detent springpin w is to oppose a resistance which enga whicihi move it'- quickly into engaging powill re tain the releasing, plate tin forward and dis-V 'tion until a force is developed sition, thus assuring an, effective movement to release the clutch-dogs. The s ring-pins a cushion the impact of the c utch-dogs against the overhanging projections t of the releasing plate, and also by virtue of their inclined abutment against or engagement with the ends of the releasing plate, assist the movement of the releasing plate into engaging position. The pushing inward or disengagement of the clutch dogs from the toothed ends of the governor-arms will disconnect the winding clutch-disk h from the sprocket-wheel r and terminate the winding or power-storing operation. The starterspr ngs having been fully wound will be ready toperform a starting operation, and as they perform the starting operationthe springs will unwind and thereby the slide-rode will be moved forward, and when the front face of the projection '0 of the slide-rod e comes in contact with the actuating springpin '0, the releasing plate, will be moved forward clear of the projections of the clutchdogs 0 and the clutchdogs will be restored to their normal positions shown, ready to be engaged by the toothed ends of the governorarms when the engine is self-actuated at the predetermined or full speed. This disengagement of the releasing plate from the clutch-dogs will occur after a comparatively small unwinding movement of the starter springs, so that if the engine is quickly started with the employment of much less than the full power of the s rings, and the pedal 17 is promptly release and the lock-wheel 1) locked to prevent further unwinding of the starter-springs, the clutch-dogs will nevertheless be released by this comparatively small unwinding movement and will be restored to their normal positions, and the cen trifugal-clutch will be ready to rewind the springs upon the development of sufficient centrifugal force from the rotation of the engine 'to cause the toothed ends of the governor-arms to engage the clutch-dogs. The consequence of this construction is that the starter-springs, altho'u h non-automatically controlled at the lock-p ate 6, are at all times sufficiently wound to start the engine, ex-

cept during short periods between a long unwinding movement and its following winding movement.

It is obvious that various modifications may be 'made in the construction shown and above particularly described within the principle and scope of my invention.
