To all whom z't may concern:
Be it known that I, JOSEPH BLTU a citi-v zentof the United States, residing at New 'York, in the county of New York and State of New York, have invented certain new and useful Improvements in Engine-Starting Apparatus, of which the following is a '15 cut, the present application is a division.
One of the objects of the invention herein claimed is to provide a simple and reliable electrical system and apparatus adapt ed to control the starting of a source of power, as an automobile engine.
Another object is to provide a practical and efiicient starting device embodying a generator adapted to prevent the premature or improper performance of certain steps in the cycle of operations of the system.
Another object is to provide apparatus'of the above type which may be readily applied. to existing installations, and safely operated by persons wholly unfamiliar with'thei de- Other objects will be in part obvious and in part pointed out hereinafter. a
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 application of which will be indicated in the following claims. v
In the accompanying'drawings, in which are shown one or more of various possible embodiments ofthe several features of the. invention, r V
Figure 1 illustrates diagrammatically an electrical starting system comprising a frictional drive between the'starting motor and the engine; I
Fig. 2 is a detail view of a magnetlcallv controlled braking device;
Fig. 3 is a sectlonal elevation'of a resistance-varying and circuit-completing device;
Fig. 4 is a diagrammatic plan of another form of starting apparatus having various i I features in common with the system illustrated in Fig. I?

Fig. 7 is a sectional elevation of a mag netically-controlled resistance-varying and circuit-completing"device; and q Fig. 8 isa detail view of a magnetic brake.
Similar reference characters refer to similar parts throughout the several views of the drawings.
In the above-mentioned application of 'which the present case is a division, there are'set forth and claimed one or more embodiments of an invention relating to engine starting apparatus, comprising a source of power such as an electric motor 1 adapted to engage positively and set in rotation at predetermined times a fly-wheel 2 or other member in driving connection with the engine 3. The engine may be of any typeincapable of starting itself, such as an internal combustion engine mounted on an automobile. In the embodiment illustrated in Figs.
1 and 6, the driving engagement between the motor 1 and the engine 3 'is effected by the frictional contact of the cone- shaped members 4 and 5 with the preferably crowned periphery of the engine fly-wheel 2; while in the construction set forth in Fig. 4, the motor is connected with and disconnected from the engine by the meshing and unmeshing of the teeth of the pinion 6 and gear 7. These three embodiments have in common -theaxial movement of one or more motordriven members into and out of engagement with the engine fly-wheel, as well as the cooperation of an engine-driven generator and a storage battery with the other elements of the starting device;
Referring now more particularly to Fig. 1, there is shown at 3 the engine above men tioned, comprising a crank-shaft 8 on which is mounted the fiy-w'heel 2, slightly crowned, as illustrated at 9.
' Driven from the engine shaft 8 as by the gears 10 and countershaft 11 is an electric generator 12 provided with a shunt field 13 and'an automatic switch 14 illustrated more or le$ conventionally as comprising a current coil 15 and a voltage coil 16 (Fig. 1)
rent through the current coil and closed whenever the voltage coil is sufliciently energized. The generator 12 is illustrated for convenience as a shunt wound machine without a voltage or current regulator, it being understood, of course, that a suitable regulator is in practice provided, and that the present invention is applicable to any suitable type of generator, regulator and automatic switch. Connected with this generator are the mains 18, 19, one leading directly to the storage battery 20 and the other to the opposite pole of this battery through the automatic switch 14.
Mounted adjacent the member 2 in suitable bearings 21 is a shaft 22 having formed thereon right-hand and left-hand threads, as shown. Upon these threaded portions are respectively fitted the members 4, preferably formed of case-hardened steel in the general conical form shown and so shaped as, upon being forced toward one another by a suitable turning of the shaft 22, to grip therebetween and be wedged into contact with the outer surface 9 of member 2. This wedging action substantially precludes slipping and is attained by the inclination or pitch of the Coacting threads upon the inner surface of the members and the outer surface. of the shaft. The latter member is driven by gear 23 and pinion 24 from the motor 1 and this gearing, as well as the ratio of the efi'ective diameters of the conical members to the effective diameter of the member 2, are so proportioned that one revolution of the member 2 or crank-shaft of the engine will correspond to about thirty of the armature shaft 25. 7
It may here be noted that terms of the nature of gear are used throughout the following claims in a broad sense as comprehending any rotary device adapted to transmit power to another member, whether by frictional or toothed engagement therewith.
Coacting with the members 4 and 5 is a swinging member 26 provided with a pair of arms 27 and 28 normally urged by aspring 29 against the outer surfaces of the cones, which are'preferably flattened as indicated at 30, 31. Swinging member 26 is secured to the pin 32 journaled in the frame of the electro-magnet 33, and the armature 34 of this magnet is also fast upon this pin and hence controls the position of member 26, the attraction of the magnetacting in opposition to the force of spring 29.
The solenoid 33 is connected across the mains 18 and 19 at a point on the generator side of the main switch 14 and is wound as a voltage coil. It will thus be seen that upon the engine being started the generator will immediately build up, thus enabling magnet 33 to attract its armature 34 and swing member 26 away from the threaded members 4 and 5.
Connected across the battery 20 is a voltage solenoid 35, the circuit of which is controlled by a swinging contact 36, conveniently positioned as upon the steering post of an automobile. This member is locked in normal open-circuit position by a swinging segment 37, controlled by the spark lever 38 in such manner that the latter must be swung to spark-retarding position before the circuit can be completed at 36. It'may also be noted that as the spark is advanced subsequent to the starting of the engine, this segment automatically throws lever 36 into open-circuit position. The circuit, comprising solenoid 35, is preferably automatically broken at another point. as by the serial connection in this solenoid circuit of a pair of coacting contacts 39 and 40, the latter being mounted upon the swinging member 26 and insulated therefrom,. and
the former being fixed in such position as to contact therewith when the member is swung upwardly by spring 29. It will thus be seen that as the generator is started the controlling circuit is automatically broken at this point by the attraction of the armature 34.
Secured to the plate 43 and insulated therefrom is a contact 52 adapted to coact with a contact 53 mounted upon and connected with the plate 49, and these contacts are positioned closely adjacent one another so that even a slight movement of core 44 from its completely depressed position will close the circuit at this point, further movement of the core being permitted by the spring formation of the arm 54 on which the contact 52 is mounted.
From contact 52 a conductor 55 leads to leads from the other side of the battery to the terminal of the motor at which the shunt coil 41 is connected, the remaining connection of the solenoid 33. Solenoid 35 will immediately attract core 44 and at the start of its movement will bring contacts 52 and 53 into engagement, thus leading current through the motor from the battery in series with the resistance medium '50, which is substantially at its full value. The core 44 in' continuing its movement adually compresses this resistance and ally shunts it altogether, this action being cushioned by the dash-pot arrangement above described. The motor will be started as soon as contacts .52 and 53' are brought into enga 'ement and will drive the shaft 22 in such 'rection as to force the members 4 and 5 toward one another, the latter being frictionally held a ainst rotation by the pressure of the arms 2 and 28. Just as the cylindrical portions 30, 31 pass from these arms the conical members are in full engagement with the then stationary member 2 and the reaction of the latter-wedges the parts securely into engagementa At this stage themembers 4 and 5,
which can travel no farther upon their threads, turn with the shaft 22 and the various parts are so proportioned and timed that just at this point the resistance medium 50 is shunted and the motor exerts full power. Through the speed-reducing gear.-
ing abovedescribedthe fiy-wheel 2 is immediately rotated and the engine started, and
by its action in driving the members 4 and 5, they travel in a reverse direction on their threads and move out of operative position toward that indicated in full lines in Fig. 1
of the drawings. The starting of theengine causes generator 12 to energize solenoid 33 and withdraw the swinging arms 27 and 28 from operative position as well as break the circuit of solenoid 35, unless the latter has already been brokenby the advancing of the spark-levler, as above described. As solenoid 35 is deenergized the weight of the parts immediately cuts in resistance 50 and then breaks the circuit of the, motor at contacts 52 and 53. If the parts still tend to spin by their inertia, the cones 4 and 5 are not again thrown toward the wheel 2, as, the arms 27 and 28 being withdrawn, they turn freely with shaft 22. In this manner any' hunting action or tendency of the conical members to move back and forth into and out of operative position after the engine is started is entirely avoided. I
In Fig. 4 of the drawings is shown a different embodiment of certain features of this invention, and in this apparatus the engine 3 (not shown) drives, through the shaft 8, a member 2, which may serve as the fly-wheel and is provided with gear teeth 7. Mounted adjacent this member, in the bearings 21, is a shaft 22 having a portion 57 upon which is threaded a pinion 6. Secured to this pinion 6 are a collar 58 and a leather disk 59, these parts being adapted to travel as a unit uponthe member 22. There is also threaded upon the latter member a nut 60 tied to the collar prevent an undesirable spinning action.
The shaft 22 is .driven by gears 23 and 24 from a motor 1, as in the apparatus heretofore described. The connections and controlling mechanism of this motor are also substantially identical with the corresponding parts of the first described apparatus, but the circuit of solenoid 35 is closed in the first instance by a push-button 62 conveniently positioned, as on the steering-post of an automobile. This circuit, furthermore, leads through the spark-lever 38 and a coacting contact plate 36 in such manner that it is necessary that the spark be retarded by movement of the lever into full-line position before the solenoid 35 can be energized.
Resiliently urged against the outer surface of collar 58, by spring 29, is one arm 63 of a bell-crank lever, the remaining arm 34 of which forms an armature for the solenoid 33 connected across the mains 18 and 19 on the generator side of the main switch 14.
project into the path of the leather The action of the above apparatus is i closely similarto that first described, but
the following features of its operation should be noted: If it be desired to start the engine 3 (not shown), the spark is retarded and the circuit of solenoid 35 completed at 62, thus gradually starting the motor 1.
This action throws the member 6 inwardly,
as its rotation is retarded by the lever 34 63, and as the teeth come into mesh with the teeth 7 collar 58 passes out from under arm 63. Pinion 6 travels fully into mesh with the gear 7, being held by the latter against rotation until it has completed its travel and rests against a fixed collar 66 on the shaft 22. At this stage the resistance 50 in series with the motor 1 is shunted and the motor exerts its full power to turn over the engine and start the same. As the engine is started it drives generator 12 to energize magnet 33 and the freely turning member 6 travels upon shaft 22 out of engagement with member 2, the motor being shut off, due to the breaking of the solenoid circuit at contacts 39 and 40. If the shaft 22 is still spinning as the member 6 withdraws into the inoperative position shown, it will not throw the latter again into mesh as the member 6 will spin with the shaft, due to the continued retraction of lever arm 63 and the nice fitting of the threads brought about by the action of spring 61. The return of pinion 6 into mesh is further prevented by the action of the flange 65 engaging the disk 59, which engagement, with the engine running, would be of itself suflicient to cause member 6 to be so rotated as to again recede from member 2. It is to be understood, however, that this engagement between the disk- 59 and flange 65 is not sufficiently positive to prevent the parts passing into operative relation when the engine is started, as disk 59 will yield in passing the then stationary flange.
In Fig.6 of the drawings there is shown apparatus which also embodies certain features of this invention. In this case the engine and its fly-wheel, together with the parts immediately coacting with the latter, are substantially identical with the corresponding parts of the apparatus depicted in Fig. 1. The motor 1 is here connected through a conductor 67 and a contact member 36 to one side of the battery 20, which may be charged from the generator 12 driven as before from the engine. The remaining motor lead passes through the series field 41 and resistance medium 50 to the opposite battery terminal. Also connected across the battery is a circuit comprising a solenoid 35 and a magnet 33 in series one with another, this circuit-being formed in part by the conductor 67 and hence being dependent for its completion upon the contact member 36. Solenoid 35 controls resistance 50, and by means of the device shown in Fig. 7 of the drawings, which, in its mechanical elements, is substantially identical with that shown in Fig. 3
' already, the corresponding parts are accordingly correspondingly lettered and their action will be clear.
- The magnet 33 controls theposition of a bell-crank braking-lever 68, which is normally retracted by spring 69 and thrown into braking position against the cones 4 and 5"'as the magnet 33 is energized.
Considering the action of this apparatus in starting an engine, the circuit is closed by contact member 36 as already described. This action completes a circuit through the motor 1, the shunt field 42 being fully energized and the series field i1 being connected through the resistance 50. The closing of the circuit, moreover, energizes solenoid 35, which gradually compresses and ultimately shunts resistance 50, and the magnet is also energized with the closing of the circuit to'bring about abraking action on the cones 1 and 5 until they have passed into engagement with the member 2, as already described. When the engine is started, it, as previously set forth, tends to throw the cones out of operative relation, and as the spark is advanced by lever 38, the circuits of motor 1 and of solenoids 35 and 33 are broken, thus'permitting the cones to reach their outward limit of travel and prevent any tendency to. again drive them into engagement with member 2.
It will thus be seen that there is herein described apparatus in which the several features of this invention are embodied. and which apparatus in its action attains the various objects of the invention and is well suited to meet the requirements of practical use.
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.
