LOCKOUT FOR AUTOMATIC STARTERS.

Original application filed September 18, 1919, Serial No. 324,450. Divided and this application filed December 26, 1919.

T all whom it may concern Be it known that I, RICHARD VARLEY, a citizen of the United States, residing at Englewood, in the county of Bergen and State of New Jersey, have invented certain new and useful Improvements in Lockouts for Automatic Starters, of which the tollowing is a full, clear, and exact descriptlon.

This application is divisional of my co- 0 pending application Serial Number 32%,450,

filed September 18, 1919. v

An object of my invention is to provide a simple and reliable device which will operate automatically to prevent the actuation of the self starter of an automobile engine while the engine is running, and thus eliminate the possibility of damaging the starter. Very many of the starter constructions in common use are liable to be injured in one wayor another it they are actuated while the engine is running. Perhaps the type most susceptible to injury are those in which a starter pinion is shittable into and out of engagement with a co-operative gear, such as a gear on the fly wheel ot the engine. If the engine does not make sutlicient noise to apprise the operator with certainty that it is running there is always the danger that he will actuate the starter under. the mistaken belief that the engine is not running, with the resultant liability of stripping the teeth on the pinion, or otherwise injuring the mechanism.

In accordance with my invention I provide an actuating memberoperatively connected to an enginedriven shaft and arranged to be moved in the proper direction by the shaft and actuate a detent against its bias into locking relation to the manually operated starter lever. Usually this lever will serve to shift the starter-"pinion and will be locked by the detent in the position in which the pinion is out otengagement with its co-operating gear wheel.

I shall now describe the illustrated embodiment of my invention and shall thereafter point out my invention in claims.

Fig. 1 is a plan of the automatic lock-out mechanism with a portion oi the starter mechanism shown in elevation in operative relation thereto;

Fig. 2- is a sectional elevation of the automatic loolcout mechanism. I

ion 1 is splined to the shaft 2 of the starter motor 3 and is shittable into and out of engagement with the gear teeth on the flywheel lby a reciprocable rod or lever 5. This rod has proper operative connection with the pinion 1 to effect the shifting movement, and for the purpose of illustration it is shown as provided with a depending fork or stirrup 6 which straddles a grooved collar on the end of the pinion 1. One end of the rod 5 is operatively connected to a suitable bell crank 7 shown as pivoted on the under side of the foot-board ot the vehicle and provided with an operating extension through the foot-board terminating in a pedal 8. The other end of the rod 5 is pivotally connected to a pivoted member 9 which I term the locking member. and which carries a knife contact 10 co-operative with thevtwo stationary starter contacts 11. A retractile spring 12 tends to hold the above described parts in the position shown with the pinion out of engagement with the gear teeth on the fly-wheel.) To look the member 9 and consequently the entire starter mechanism in the position shown when the engine is running, suitable automatically operated detent mechanism is provided which will now be described.

'In the form shown this mechanism is enclosed in a-suitable housing 13 provided with a horizontal wall or platform 14 on which the member 9 is pivoted. The member 9 is provided with an extension 9 beyond-the pivot and co-operative with this extension is a detent 15 which is also pivoted in a suitable bearing in the wall 14 and which is provided with a nose arranged to be moved into and out of the path of the extension 9 as the detent 15 is rotated on its pivot. A retractile spring 16 tends to hold the detent 15 against a stop 15 with the nose out of the path of the extension 9. v

To actuate the detent '15 against its bias into the path of the extension 9 suitable transmitting means are provided having operative connection with an engine-driven shaft 17. For the purpose of illustration I have chosen atransmission device of the type shown and described in my (Jo-pending application. Serial No. 314,643, although it will be understood that any suitable mechanism actuated by the shaft 17 may be employed for this purpose.

In the illustrated construction the primary member of the transmission comprises an annular cup-shaped member 18 secured aX ially upon the shaft v 17 immediatelyabove a suitable anti-friction bearing forthe shaft 17 formed in the wall 14. "The secondary member 19 rests on top of the primary memher and is an annulus providedat its inner edge/With a hub portionwhich loosely surmember, and therefore is free toturn thererounds the center portion ofthe primary on. '-A sui.table cover 20 encloses'the device.

The primary me'mber18 :is provided with a plurality of concentric [flanges 18% intermediate ofwhich' are similar depending flanges 19 on'the secondary member. The device is partially filled withoil or other 'l'iquid ivhich servesto couple'the twomembers and transmit-a torque to the secondary member. The secondary member carries an abutment-"21 in position toengage the end of the pivoted detent 15:0pposite the nose portion. Since theshaft 1'Zis. driven in a clockwise direction as viewed inlTig. 1, it follows that the drag'of the primary member upon the secondary member will cause the latter to rotate in a clockwise directionwhen 'the engineis running, and the abutment 21 and means mechanically connecting shaft to the lock-outandoperative'by any running.

will thereby actuate the detent 15 against the tension of the spring 16-and move the nose-down into the'path ofthe extension 9 The starter-mechanismasthereby locked against actuation so long as the engine is It is obvious" that various modifications may be made in theconstruction shown 1n "the-drawings and above particularly described within invention.
