A.
pinion- 2 is slidably jOum Hea on the power shaft for movement into andou't of mesh with a member such as a flywheel gear 3 of an engine to be started. A driving clutch member 4 is fiiied on the power shaft l in any suitable manner as by forming flats 5 on the shaft cooperating with a corresponding opening in the clutch member,
with retainih rih flt preventing longitudinal movement of the clutch member.
A flange member 1 rigidly mounted ths; pinion 2 in any suitable manner as'indicated at 8, and a barrel member 9 is rigidly mounted in the flange member Tasb'y' means of lugs ll riveted or welded'in openings l2 in said flange (Fig. '7). A coupling t ini iefls (Fig. 6) is slidably mounted in the barrel :9 and is provided with radial lugs l4 traversing long'itudinal slots l5 the'barrel in ord r to spline the t himb-le tothe' barrel. A shiftcollar I6 is slidably mounted on the exterior of the barrel in overlapping relation with the flangeiiieihb'er i beiiig' retained n the barrel by means-of a split lock ring 11. A spring 18' in the form. of a dished annulus is interposed between the shift collar 16 and the ends of the lugs M of thimble I3, and a secondspring I9 is interposed between said lugs: and the flange member'! whereby/longitudinal movement or the shift collar by any" conventional shifting means is' yieldably' transmitted to the thinible l3 and to the pinion 2.. i i i A driven clutch member 2! (Fig. 6) is splined in the thimble ['3 as by means of lugs 22 traversing slots 23 in said thimble. 'A dished disc spring 24 is mounted in the thimble I 3 and connected for longitudinal movement therewith as by means of a shou1'der25 and a lock ring 26 in the thimble engaging the opposite sides of the disc. The inner periphery of the disc is connected to the driven clutch member 2| by suitable means such as a thimble 21 riveted as indicated at 28 to the center of the driven clutch member whereby the driven clutch member is yieldably connected by the disc spring 24 for longitudinal movement with the thimble l3.
Centrifugal means for deflecting the spring 24 in order to assist the withdrawal of the driven clutch member 2| from engagement with the driving clutch member 4, is provided in the form of weight members 29 fixed as indicated at 3| to the disc member 24 and operative under the influence of centrifugal force to flatten the disc as shown in Fig. 4 to cause disengagement of the clutch members.
In the operation of this embodiment of the invention, starting with the parts in the positions illustrated in Fig. 1, movement of the shift collar I6 to the left by any conventional form of manually or magnetically operable shifting means moves the pinion 2 into engagement with the engine gear 3 and the driven clutch member 2| into engagement with the driving clutch member 4 as illustrated in Fig. 3. The starting switch is thereupon closed in the conventional manner to cause rotation of the power shaft l which is transmitted through clutch members 4, 2|, barrel 9 and flange member I to the pinion 2 whereby the engine member 3 is rotated to crank the engine. When the engine starts, the acceleration of the engine gear 3 causes the pinion 2 to overrun the power shaft whereby the clutch member 2| is caused to back away from the clutch member 4 due to the inclination of the backs of the clutch teeth as shown at 32. At the same time, centrifugal force acting on the weight members 29 causes the disc spring 24 to be flattened, thus completing the disengagement of the clutch member 2| from the clutch member 4 and holding the clutch members disengaged as long as the rapid rotation of the pinion 2 continues. Since the clutch members are thus completely disengaged, it will be understood that the overrunning action takes place quietly without any ratcheting action. When the shift collar I6 is returned to idle position and the pinion 2 is no longer rotated by the engine gear 3, the starting switch is opened in the usual manner and the parts re-assume their normal positions.
In case, during the meshing movement, a tooth of the pinion abuts against a tooth of the engine gear as illustrated in Fig. 8, the spring I9 compresses and permits the shifting movement of the collar IE to continue until the driven clutch member 2| engages the driving clutch. member 4, after which closure of the starting switch causes rotation of the pinion to index it into proper registry with the engine gear, whereupon the spring l9 expands and snaps the pinion into mesh with the engine gear and cranking takes place as above described.
In the embodiment of the invention illustrated in Figs. 9 to 13, the parts are in general the same as in the first embodiment of the invention and are similarly numbered. Instead of the disc spring 24 for connecting the driven clutch member 2| to the thimble l3, however, in this embodiment of the invention a coil spring 34 is mounted in a thimble |3a seated against a shoulder |3b therein and bearing against the driven clutch member 2| a. A cam member 35 is slidably mounted in clutch member 2| a in position to cooperate with the rounded head of a pin 36 mounted in the end of the power shaft Centrifugal means for moving the cam member 35 radially is provided in the form of a weight member 31 riveted as shown at 38 to the cam member 35 and normally held in a position to centralize the cam member by means of a spring 39. When so centralized as indicated in Fig. 9, the cam member receives the head of the pin 36 in a socket 4|, thus permitting the driven clutch member 2| a to engage the driving clutch member 4. When the cam member 35 is moved radially by the centrifugal weight 3'|, however, the driven clutch member is cammed out of engagement with the driving clutch member.
The operation of this embodiment of the invention is substantially the same as the previous embodiment, the centrifugal means 35, 31 serving to maintain the clutch members disengaged during the overrunning of the gearing, and returning to normal position when the gearing is disengaged and the starting motor permitted to come to rest.
