arter manually, I prefer to extend the p 1 ex I protectfthe-projeca this 'ing e'n d Of tllG shaft 23 and the clutch 57 or flevfe'r i may be conveniently applied for the manual operation of the counter-shaft. Assuming that the various elements which make up my spring starter are in the position shown in Fig. 1 of the drawing, the male clutch member 57 being out of engagement with the female clutch 56 and the nut 41 screwed up to the left-hand end of the screw-threads 40, the main shaft 23 of the starter which is connected with the crankshaft of the internal-combustion engine may freely revolve in its bearings without affecting any other portion of the mechanism of the starter. This position of the starter last described is the unwound position, and it will be assumed that while the starter is in this condition, the internal-combustion engine is operating under load. It is the customary practice to release the clutch mechanism of such engines, that is, to unload the engine, before stopping. the same. When, therefore, the operator of the engine desires to stop the same, he will first operate the clutch pedal 23 to remove the load from the engine. 31 of my self-starter being connected to this clutch-operating mechanism so that the cable 33 is pulled at the time of disengagement of the clutch, the lever 31 will be rocked about its pivot and will operate upon the head 29 of the bushing 27 to withdraw this bushing from the casing 21, thereby shifting the shaft 23 longitudinally in its bearings until the male clutch 57 engages the female clutch 56, this shifting movement 0 the shaft 23 being permitted by its oonnections with the shaft of the internal combustion engine.

The continued operatlon o the internal combustion engine will drive the shaft 23 and through the clutch mechanism 56, 57 and sprocket and chain connections 53, 52, 51, will drive the rewind counter-shaft 49. The rewind pinion 48 of this shaft being in engagement with the hub gear 46 will thereupon rotate this hub in a counter-clockwise direction, as viewed in Fig. 3, to coil up or wind the spring 45. It will be understood that this rotation of the hub 35 will be permitted b the roller clutch connecting the same with the shaft 23. As the hub 35 revolves, the traveling nut 41 which is threaded therein will be moved to the right, as viewed in Fig. 1, the screwthreaded engagement between the hub and the nut I such movement, until at the time the spring 45 is completely rewound, the right-hand end of the nut 41 will engage the thrust bearing 43. and positively force the shaft 23 to the right as viewed in Fig. 1, thereby disengaging the clutch 57 from the clutch 56. Either the cable 33 or the lever 31 or some other portion of the mechanism connecting these parts with the clutch of the internal combustion engine is designed to have sufficient The cable 33 attached to the lever being properly designed to efiect elasticity to permit of this shifting of the shaft 23. As soon as the clutch 57 has been disengaged from the rewind clutch 56, the hub 35 will come to rest, the spring being prevented from unwinding by reason of the spring-lock 59 of the counter-shaft 49. The starter is now rewound and the internal combustion engine may be stopper. It will be understood that the normal rate of speed of an ordinary internal combustion engine is so high that, in practice, the rewinding operation above described will be completec in the minutest interval of time and practically coincident with the disengagement of the clutch mechanism of the internal combustion engine, so that immediately after such disengagement the engine may be stopped as in common practice.

When it is desired to start the engine, the release lever 61 will be oscillated in a counter-clockwise direction as viewed from the left-hand end of the shaft 49 in Fig. 1, whereby the locking coil 59 of the countershaft will be released from its engagement with the same. The force of the spring 45 acting upon the hub 35 will then cause the latter to revolve in a clockwise direction, as viewed in Fig. 3, whereby the rollers 38 are forced upwardly upon the cam eXcrescences 39 of the main shaft 23, and this latter shaft is rotated in its normal or-forward direction to start the internal combustion engine. During this clockwise rotation of the hub 35, the screw-threads 40 thereof will act to retract or move the nut 41 to the left, so that when the spring is completely unwound this nut will again occupy the position shown in Fig. 1 of the drawing. This completes the cycle of operation of the starter.

In Fig. 6 I have illustrated a modification of the re-wind counter-shaft and the method of mounting the same upon the casing. In this modification the casing 21 has a tubular boss 67 cast integrally therewith which receives and supports a stub-shaft 68 shouldered intermediate its length as at 69 and locked in position by means of a nut 70. The outwardly extending headed end 70 serves as a journal for a rewind pinion 71 and sprocket 72 which are preferably secured together as by the screw-threads shown in the drawing and correspond with the pinion 48 and sprocket 51 of the construction shown in Fig. 1 Beyond the sprocket 72 there is journaled upon the shaft end 7 O a brake pulley 73. Between an outer hub 74 of this brake pulley and a mating inner hub 7 5 formed on the sprocket 7 2, there are mounted clutch rollers 7 6, the two hubs and these rollers forming an automatic clutch of the general type shown in Fig. 3. The brake pulley 73 is designed to have applied thereto any preferred form of friction brake, by means of which the pulley and consequently the sprocket 7 2 and rewind gear 71 may be locked to-prevent un and may be released unwind for the pu motor.

The spring starter is now rewound and in condition to serve as a source of power for rotating the fly-wheel 7 8 and through it the internalcombustion engine for starting the same. t will be understood that in this form of construction the clutch lever 84: must be allowed to move backwardly to permit the clutch 7 9 to engage the fly-wheel 78 when it is desired to start the motor.

1n Figs. 9, some modifications of the rewind clutch and starting clutch. In Fig. 9 the main shaft of the starter, designated 95, has a collar 96 formed thereon by which the shaft may be shifted to the right by the traveling nut 97, which corresponds to the nut 11 of Fig. 1, or the nut 86 of Fig. 7. This traveling nut '97 is threaded into a hub 98 and is prevented from rotating by the studs 99 with which the slotted ears 100 of the nut engage. In place of the roller clutch connecting the hub and the shaft, as shown in Figs. 1 and 7, I have shown in Fig. 9 a coiled wire similar to the counter-shaft clutches shown in Figs. 1 and 7. This coiled wire clutch, designated 101, has its end 102 secured to the hub 98 and its opposite end free and in frictional engagement with the shaft 95. It is clear that when the hub 98 turns in the direction indicated by the arrow in Fig. 9, the free end of the wire coil 101 will by its frictional engagement cause the coil to tighten upon the shaft 95 and eventually give a driving engagement with the same. When the hub 98 rotates in the opposite direction, however, the wire coil will automatically loosen itself to permit the hub to turn free of the shaft.

For operating the rewind sprocket 102 of the construction shown in Fig. '9, I have provided a modification of the coiled wire clutch. In this modification the shaft 95 is surrounded by a bushing 103 which is splined to the shaft as shown at 10 1, to permit of the requisite longitudinal sliding of the shaft. The coiled wire, here designated 105, has its large end 106 turned outwardly and caught in a suitable aperture in the rewind sprocket 102 and has its small end turned forwardly and engaged in an aperture 107 in a male clutch member 108 mounted for rotation on the end of the rewind sprocket 102 and prevented from shifting longitudinally with respect thereto by the set-screws 109 which travel in the groove 110 turned in the cylindrical hub portion of the sprocket 102. For cooperating with the male clutch 108, there is provided a female clutch member 111 rigidly secured to the shaft 95 as by a set-screw 112. The rewind sprocket 102 is held in its proper assembled relation by a split col 10 and 11, I have illustrated The bushing 116 has a lar 113 fastened to the face of therewind gear 114 of the hub 98 and bearing against a shoulder on 1 the hub of the rewind sprocket.

The operation of the modified form of rewind sprocket clutch shown in Fig. 9, is as follows: V7 hen the shaft 95 is shifted to the left by some suitable means as by the by the lever 84: of

Fig. 7, the female clutch 111 which is securedto the shaft comes into engagement with the male clutch 108. Continued rotation of the shaft 95 therefore operates to turn the clutch member 108 and by its connection with the end. of the spring 105 serves to forcibly tighten this spring upon the bushing 103, thereby causing the spring and bushing to become locked together. The bushing being keyed to the shaft 95 therefore drives through the spring directly to the rewind sprocket 102, the sole function of the relatively small or light clutch members 108, 111, being therefore to maintain the spring 105 coiled tightly upon its bushing. When the clutch 111 is released as by the inward shifting of the shaft 95, which is accomplished by the traveling nut 97 when the spring has been rewound, the clutch member 108 will thereby be f and the elasticity of the-coil 105 will cause it'to unwind, thereby releasing the bushing 103 and permitting the sprocket 102 to come torest. It should be noted that this formof construction differs from the coiled wire clutch hitherto described, in that the coil 105 is so wound as to have a slight clearance upon its mandrel in place of having frictional engagement therewith as was necessary in the previously described forms of coil clutches. In the normal or unstressed condition of the coil 105 therefore it is expanded clear of its bushing 103 and the latter may rotate in ei her direction without causing the coil to bind. It is only whem'by operation of the clutch 108, the coil is tightened upon the bushing that the automatic locking action takes place. While in Fig. 9 1 haveshown the clutch 108, 111 as being of the conventional cone or friction type, it will be readily understood. that this clutch might be of any approved design, such, for instance, as a roller clutch. In Fig. 10, I. have shown such'a roller clutch applied to the end of a coil 113 designed to replace the coil 101 shown in Fig. 9. e main shaft, here designated 95, has formed thereon cam excrescences 11 1 which cooperate with rollers 115 and a sleeve or bushin 116 to form a complete roller clutch. flange 117 formed on one end in an aperture of which flange the free end 118 of the coil 113 is caught. The open end of the bushing 116 may be closed by a collarv 119suitably fastened to the bushing and it is'apparent that the bushing 116 ting-the inectedtherewith and one end connected with s rin from a starter shaft connected with the connected with will serve to replace the fixed collar- 96 on theishaft 95. of Fig. 9, so that the, assembly represented by Fig.v 10, may be placed bodily within the hub mechanism of Fig. 9.
