PatentedJune s, 1920.

Original application filed June 25, 1913, Serial No. 775,670. Renewed November 23, 1918, Serial No. 263,947. Divided and this application filed February 24, 1919. Serial No. 278,918.

To all whom it'mag concern: ie it known that I, Josnrn BIJ R, a citizen of the United States, and a resident of the. borough of Manhattan city of New York, county and State of ew ork, have invented an Improvement in Engine-Starting Apparatus, of which the following is a specification.

This application is a division of my application for engine starting apparatus, filed June 25, 1913, and issued June 17, 1919, as Patent No. 1,307,177.

This invention relates to engine-starting apparatus, and with regard to certain more specific features, to electrical means for starting internal combustion engines.

One of the objects of the present invention is to provide practical; inexpensive and durable means for setting in rotation an automobile engine-or other prime mover incapable of starting itself.

Another object is to provide apparatus of the above type in which the source of power used for starting the engine is positively, effectively and completely disengaged from the engine when the latter has started, regardless of the position of the manually operated parts.

Another object is to provide starting apparatus embodying a reliable and durable automatic disengaging device whose action is wholly independent of electric currents.

Another object is to provide a compact arrangement of parts wherein centrifugal force acting upon suitably disposed masses is utilized to nnmesh a gear and pinion connected respectively with the engine and the starting motor.

Another object is to provide a simple and durable starting apparatus of few parts, inexpensive to manufacture, easily assembled and efficient in action.

Other objects will be in part obvious and in .part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the ap- I plication of which will be indicated in the following claims.

In the accompanying drawing, wherein is shown one of various possible embodiments of this invention,

Figure 1 is a diagrammatic view of starting apparatus;

Figs." 2 and 3 are similar views of the same apparatus showing the parts in different positions; and

Fig. 4 is a detail plan view of a portion of the apparatus shown in Fig. 1.

fnmilar reference characters refer to similar parts throughout the several views of the drawing.

By wayof explanation, it may be stated that the present invention is directed, in some of its more specific features, to the starting of automobile engines.

Referring now to the drawings, and more particularly to Fig. 1, there is shown at 1 a member, such-as a fly-wheel, in driving connection with the engine ,(not shown), to which the starting apparatus is applied. On this fly-wheel 1 is a gear 2 adapted at predetermined times to mesh with the teeth of a pinion 3, the latter being feather-keyed upon the shaft 41 of an electric or other motor 5. Inasmuch as an electric motor is preferred for rotating the shaft upon which the pinion 3 is mounted, such a motor is illustrated in the drawings, with its field '6 and armature 7 in series with each other and with the main switch 8.

The pinion 3 is provided with suitable teeth 12 adapted to mesh with the teeth of gear 2 upon the pinion being moved endwise as hereinafter described.

In thisillustrative embodimentof my invention, there is provided a foot pedal 22 co-actingwith a retracting spring 23 in swinging a bell crank lever 2&1, the lower arm of which is provided with a pin-andslot connection witha reciprocal rod 50.

A preferred means for supplying current to the motor is illustrated in Fig. 1 as comprising the main switch 8 whose movable contacts 27, :28 are. mounted directly on the horizontal shaft 51. As indicated in Figs. 1, 2 and 3, a slight movement of the shaft 51 is sufficient to establish anelectrical connection between the movable contact 27 and the fixed contacts 29, 30, thereby completing a circuit from the positive side of the battery 31 through the armature 7 and. field 6 of the motor, starting resistance 32, fixed contact 29, movable contact 27 and fixed contact 30 to the negative side of the bat tery, and as a result the armature 7 and pinion 3 rotate slowly.

It will be seen that if a slight amount of current be supplied to the motor in order to set it in slow rotation, the pinion will turn sufliciently to insure meshing with the teeth of the gear as soon as the former has moved sufficiently far toward the right.

The means whereby this meshing movement of the pinion is brought about in this illustrative embodiment of the invention, is as follows: The reciprocal rod 50 above referred to, is connected with the shaft 51 of the switch 8 and with a grooved collar 48 on the extended shaft 4:. Between this collar 48 and pinion 8 are a pair of toggles each comprising a pair of links 49 pivoted one to another and weighted as shown in Fig. a of the drawings at 4 7. These toggles are normally held in extended position by the spiral spring 52 about the shaft.

The swinging of the bell crank lever 24 about its fixed pivot not only actuates the switch rod or shaft 51 as above described, but slides collar 48 along the shaft, and acting through these toggles and the spring 52, moves pinion 23 into mesh with the gear 2. It will be seen that the collar 48 occupies a limiting position in Figs. 2 and 3, the switch 28 acting as a stop means to prevent further movement of said collar.

In order to prevent downward movement of the pedal 22 which as above described causes meshing of the pinion with gear 2, when the engine is running, there is provided at a locking detent controlled by the magnet 36 energized from the generator 37 which is driven from the engine. This detent co-acts with a locking groove 4:3 in the pedal 22. The construction and action of these parts form in themselves no part of the present invention and are more fully described in my Patent No. 1,307.17'7, above referred to.

There is also provided in this case an automatic switch -16 controlled by a series coil 4% and shunt coil 45 to govern the connection of the generator 37 with the switch battery 31.

In the present embodiment the pinion is moved toward the left, out of engagement with the gear, either by releasing the pressure on the pedal 22 and allowing the spring 23 to rotate the bell-crank lever 24: clockwise or by the outward movement of the weights 4L7 secured as indicated, to the pinion 3 and collar 48 by the pivoted links 49 as above described.

\Vhen the engine is to be started the pedal 22 is depressed, thereby moving toward the right the horizontal shaft 50, collar -8, and switch rod 51. One or more of the weights 47 may at this time tend to buckle outward,

' spring, effect the movement of the pinion 3 toward the gear 2. In this manner the force or power for the meshing movement is transmitted from lever 2i and thence from member i8 to pinion 3 through coil spring 52 and thus the endwise movement of the pinion is yielding. Connection is made at the auxiliary contacts 29, 27, 30 of the main switch 8 to set the motor in slow rotation prior to engagement, and, as soon as engagement is completed, the closing of the circuit at the main contacts 33, 28, 34: short-circuits resistance and energizes the motor suliiciently to enable it to start the engine. As soon as the engine has started to rotate under its own power, the increased angular velocity of the weights 4? causes them to fly outward and thereby disengage the pinion from the gear 2 even though the pedal 22 remains depressed. Premature reengagement is prevented by the continued rotation at high speed, of the weights 4 7 as long as the pedal is depressed, since the upward movement of the pedal by dei nergizing the motor only after connection is broken at the auxiliary contacts 29, 27, 30 insures the continued rotation, at high speed, of the weights until the collar 48 has almost reached the end of its leftward travel. While the engine is in rotation the interlock 35 prevents the downward movement of the pedal.

Briefly summed up, the operation is as follows :-lVhen the engine is to be started, the pedal 22 is depressed, thereby slowly rotating the motor while the pinion 3 is moved toward the gear and then sending a heavy current through the motor as soon as engagement between gear and pinion has been effected. l.)isengagement is effected by the out n rd movement of the weighted links -19 connected respectively to a pedal-controlled member and to the pinion 3.

As many changes could be made in the above construction and many apparently widely different embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.
