To aZZ whom 223 concern:

Lie it known that i, ALmoN D. T. LIBBY, a citizen of the United States, resident of Urange, county of Essex, State of New dersey, have invented certain new and useful Improvements in Starting Mechanisms for Hydrocarbon-lilngines, of which the following is a specification.

My improvement relates to the means of starting a hydrocarbon, or internal combustion engine, and as illustrated in the drawings accompanying this specification, relates more particularly to an engine used in an automobile. I do not wish, however, to be limited to the use of my improvements, to an automobile, as they may be applied to any type of engine, which it is desired to start in a simple and expeditious manner. In the early types of automobiles, and in some that are being made today, the engine is started by means of a crank at the front end of the car, but in order to make it easier and more convenient, certain mechanisms have been applied to the engine in such a manner that the same can be started from the drivers seat by pushing down on a pedal with the foot, which act engages the pinion with a gear cut, on or attached to the fly wheel of the engine, at the same time, closing the battery circuit through the windings of the motor. The great objections to starters of this nature, is, that they take an excessive amount of current from the battery used for this purpose, both at the instant of closing the switch, and subsequently during the'operation of cranking the engine, as they start at a slow speed, under a dead load, and this load has to be carried until the speed increases, to such a point as will cause the ignition apparatus to work, and the engine then runs from its own fuel.

These types of starters are also subject to difficulties of meshing the pinion with the gear onthe fly wheel, and the consequent danger of stripping teeth from the'gears. Considerable strength is also required in many cases to engage the pinion with the fly wheel gear against the action of the spring, which must be stiff enough to throw out the pinion, when the foot pressure is released from the pedal, thus making the'operation hard for lady drivers, for whom the engine starting devices are aspecial boon.

By my improvement, I start the motor "under no load, or, at least, a very light $pecification of Letters Z'Eatent.

load, due only to the inertia of the gear set, and a small fly wheel mounted on the end of the motor shaft. When the motor attains approximately its maximum speed, or any predetermined speed, the gear set is then engaged, and likewise the motor, which is connected to the gear set, with the engine. As shown in the drawings, this engagement takes place through the medium of the fly wheel, yet, I do not wish to be limited to this precise manner. By this method of operation, I reduce the power consumption taken from the battery to a minimum, and begin to turn the engine over at a maximum speed right from the start instead of turning it at a minimum speed, and then bringing it up to the speed of ignition, as in methods now in vogue. By cranking the engine in this manner, at its maximum speed on the start, the ignition devices are in a condition to operate at once, and the engine begins to fire its charges with the least possible delay. My improvements are illustrated in the fol; lowing drawings, in which like characters are used, to represent corresponding parts in the various figures.

Figure 1 is a side elevation, showing a portion of one of the engine cylinders on the left, and the fly wheel to the right, between the two of which, a portion of the gear set, and other mechanism, is mounted.

Fig. 17 is a simplified form of Fig. 11 in which manual control means are used lnstead of automatic devices.

Referring now to the details, 1 represents the fly wheel of the engine, to which 1s attached a flange 2, which as shown, is held thereto by means of thebolts 9 and nuts 57,

although this fiange may be made integral with, the web of the fly wheel.

Mounted in any suitable manner on the engine frame is a gear wheel, 12, to which is attached a flange 3. Tn the drawings, this flange is shown attached to the gear wheel by means of bolts 6, although it may be made integral. Carried by this flange, is a resilient member 5, commonly known as a brake band, the inner surface of which is lined with a friction material 1, which may be of leather, raybestos, or other suitable material. One end of this brake band is secured to the flange 3, while the other, or, free end, is attached to a lug 29, shown in Fig. 3, and this lug is associated with a plunger 30, ot a solenoid 51, supplied with a suitable winding 50. The movement of the plunger, and likewise. the tensio on the brake band, is regulated by means of spring 28, and nuts 27, mounted on the threaded entension 26, of the plunger 30.

Also mounted on the gear wheel 12,is a set of slip rings, 18, shown in Fig. 5. These rings are mounted on a suitable insulating block, and the whole attached to the gear wheel in any suitable manner, such as by two screws shown in dotted lines, these screws being set into the insulating material, below and out of contact with the slip rings.- One pair of these slip rings is connected to the winding 50, of the solenoid. ()ne of the rings of the pair above referred to, is connected to a block 20, which is attached to the slip ring block 13, by means of screws 21. Mounted on block 20, is a resilient member 23, which can be adjusted by an adjusting and rotated by the shaft of the motor.

screw 22. On the end of this resilient member 23, is a weight 24... To the third slip ring is connected an insulated contact 25, which is mounted on the exterior surface of the block 13. The pressure on the contact 25, can be adjusted by means of the screw 22, and this adjustment is so made that the contact 25 is opened, when the speed of rotation of the wheel 12, reaches a certain prede-' termined point, at which speed the weight 241 is thrown outward, opening the contact at 25. The electrical circuit connections are carried to the slip rings through the medium of the brushes 32, which are mounted on the block is made so that it can be readily re moved for inspection it necessary, it being divided along the lines 108. The gear wheel 12, and the fly wheel 1 are so related inposition, that the bralte band 5 encircles the flange 2 on the fiy wheel, so that when current is passed through the winding 50, of the solenoid 51, the brake band is drawn down and clutches the flange 2.

The controller, or governor, 54:, mounted on the motor 53 and shown in Figs. 7 and 8, has a flange 47, which is attached to the end of the bearing of the motor in any suitable manner, it being shown threaded, and at tached to this flange are insulating members a1 and 102. Through 41 passes a brush holder of insulating material 42, said holder carrying the brush 15, connections being made to the holder by the nuts 43 on the stem 4:1. The brush -15 runs on a metal ring 36, which is carried on another insulating member 37, the member 37 being attached to Attached to ring 36, by a screw or other means, 38, is a. resilient member 39, on the end of which is a contact point 40. ()n the interior wall of the ring 11, is a metallic ring 46.

Attached to this ring is a metallic stud 49. The resilient member 39 is adapted to be thrown outward from the center, as the motor rotates, until the contact engages the metallic ring 46, at which time an electrical circuit is completed from the stud 44 through to stud 19.

In .one of the modified forms of my invention, shown in Figs. 9 and 10, the engagement is made with a fly wheel by means or the members 61, which are carried on studs 64, the same being fastened to the gear wheel by nuts 62, the members 61 being pivoted at 63. The members 61 may be faced with friction material, and are adapted to engage the inner surface of the fly wheel. I. hen this form is used, the flange 2, shown in Fig. l is not needed.

which are carried by the member 68, in a similar manner as the rings 18 ot big. 5..

Mounted on the shaft, is member o5, which is free to slide back and forth. This member has projections 71, which project into the recesses T2 of the core of the magnets 66, on which are wound coils 70. lVhen these coils are energized, member is drawn to ward the gear wheel 60, and the members 61, are rotated about the pivot 68, until their faces engage the rim of the fly wheel. lhis engagement takes place before the member (35 reaches the end of its movement, so that the fly wheel is gripped securely by the members 61, and is caused to rotate with the gear wheel 60. A similar controller or governor, as shown in Fig. 3, is mounted on the block 68, the spring or which is shown at 23.

In another modified form of my invention, shown in Figs. 12 and 13, the gear wheel 84.- is provided with core projections 83, on which are mounted coils S2, and attached to the cores by screws or bolts 80, are pole shoes 81. These pole shoes engage the rim of the fly wheel at 107, when the coils become energized, as the entire wheel Si is loosely mounted. so that when the coils 82 are energized, it is drawn toward the fly wheel, the small pinion engaging the teeth on the gear wheel- Sl. being made longer than the face of the said gear wheel, to allow for this slight movement. Mounted on the gear wheel are slip rings, 18, similar to those shown in Fig. 10. The governor mechanism is also mounted on the same mounting block along with the slip rings. lVhen the arrangement of Fig. 12 is used, the rim 107 of the fly wheel may have inserts of non-magnetic material of the proper circumferential length properly spaced apart so the pole shoes 81 will give the maximum pull, greater than if they engaged a continuous ring of magnetic material such as shown at 107.

lonsidering now, the general operation of my system, and referring particularly to Fig. 11, the push button 56, is mounted on the dash board. or in any convenient place, on the vehicle, and in order to start the-en gine, this button is pushed in and then released. The act of pushing in the button allows current to flow from the batter)? through the relay winding 55, which energizes the core, drawing up the armatures and closing the contacts 58. and 59. The closing of the contact 58 supplies battery current to the electric motor 53. Phe detail connec Hons of the inside of the motor are so well 5 known, that they are not described herein,

the binding posts only, being shown on top of the motor. The closure of the cor tact 59, allows the battery current to dew through the winding of the relay. and by means of one of the brushes 32, and slip ring 18, through the Contact 25, of the goi ernor device on the gear wheel 12, back the other side of the battery, thus looking a ie relay in its operated position. As soon as the current goes tl'irough the electric motor, this immediately starts and comes rapidly up to its maximum speed. Eitany predetermined point near this maximum speed, the automatic governor 51 operates by throwing out the spring 39, so that the contact 40 engages the ring ll), thus allowing the current to How from the brush l2 through the governor to the stud l9, and through the relay device 52 to one of the brushes and slip rings 18. through the coil 50 of the solenoid 51, to the outer slip ring 18, back to the other side of the battery. This flow or current through the relay device attracts its armature. The relay device is locked in position through the contact 105, so that as the speed of the motor diminishes after the load is thrown on, the current through the solenoid winding will not be interrupted. At the instant the current passes through the solenoid winding 56,

the plunger is attracted, and the brake band 5 is drawn together. bringing the triotion surface 4 into engagement withthe flange 2 on the fly wheel.

As has been hitherto described, the plunger 30 is made to be readily adjustable, so that the clutch can be increased or diminished in tension, as desired. During the interval, from the time the current is closed on the motor until the clutch acts, a large amount of energy is stored up in the fiv wheel F, and at the instant the clutch seizes the fly wheel, or other part of the en gine which it is designed to engage, the shock of the engagement is absorbed by the energy of the fly wheel F, so that the motor does not draw any greater amount of current for some little interval of time, and the engine is turned over at its maximum speed, immediately. Should, for any reason, the ignition devices fail to operate at once, the entire combination will keep on turning, and as the energy of the fly wheel F is absorbed, in doing work on the engine, its speed, and the speed of the motor will decrease, and the motor will begin to draw more and more current until it reaches a certain value, and it will continue turning the engine at this stated amount of current until the driver sees that something is wrong and desires'to shut off the power, which he can do by pushing the button 106, which breaks the locking circuit on relay 55 and consequently cutting off the current to the motor, relay 52 and the clutch.

Assuming however, that the engine fires immediately, it will at once pick up in speed much faster than the motor 53 has been turning it, and as soon as it increases in speed to a predetermined point, the governor weight 2% is thrown outward, and the contact 25 is opened, thereby breaking the look through the winding of the relay 55, thereby cutting the current 0d the motor, the relay device 52, and the clutch. It is thus seen that the system as described is entirely automatic, merely necessitating the pushing in of a small button, which can be mounted in any convenient place on the vehicle.

tVhile l[ have shown and described an automatic system, yet, ll do not wish to be limited to the exact forms shown, as it is perfectly feasible to perform certain of the automatic features manually. For example, 1 may use a manual controlling switch which in its first position, may throw current on to the motor, and in its next position, close a circuit through the clutch, thus dispensing with the relays 52 and 55, and push buttons 56 and 106. 1n this case, the operator will cut the current 011 by the switch, immediately the engine starts, although no harm will result, even though the current be kept on. I arrange and-.adjust the preferred form of my invention so the engine tends to run away from the clutch, when the speed of the engine becomes faster than the gear set. 1 may also close the clutch winding at the instant of applying current to the motor, and start from on dead load, or, 1 may use a magnetic means of engaging a gear cut, on, or attached to a fly wheel with a sliding pinion, doing so at the instant of starting, and 1 may also incorporate the magnetic clutch within the gear set, connecting one side of the clutch member to the engine, letting it run idle with the engine, when the starter is not in use. 1 may incorporate my automatic clutch as a part of the regular clutch, especially where the regular clutch is of the cone type, in which case the cone clutch is released from the engine in the usual. manner, until the starting motor is up to speed, when the cone clutch is released and engages the engine fly wheel.

1 will briefly describe these modifications.

In Fig. H, 19 illustrates a portion of the engine 1, the fly wheel. 12 is a large gear wheel, the same as shown in Figs. 1 and 2, but in this case, it is fastened securely to the fly wheel 1 and rotates with it. starting motor 53 is connected by means of a pinion, l to a gear wheel 119, which is carried on a suitable shaft 120. Mounted also on shaft 120 is another gear wheel 118. Gear wheels 118 and 119 are so constructed that in a space between them there is mounted a coil 121, and when the motor The I 53 reaches a certain predetermined speed, the circuit is closed through the coil 121 in the same manner as has been described in the operation of the apparatus shown in Fig. 11. As soon as current passes through the coil 121, the gear wheel 119 is drawn toward the gear wheel 118 and they engage along the surface 122, thereby forming a magnetic lock, and the gear wheel 118 is then carried along with 119, and movement is transmitted to the engine through the gear wheel 12. When the engine picks up from its own power the circuit through the coil 121 is opened in a similar manner as described in Fig. 11.

1n Fig. 15, the automatic clutching elements consist of gear wheel 125, brake band 126 and member 12:: arranged. in a somewhat similar manner as shown in Figs. 1, 2 and 3. 1n the operation of this modified form, the regular engine clutch 123 is released from the fly wheel 1 before the current is applied to the starting motor 53.

As soon as the motor 53 reaches a certain speed, the clutch members 12%, 125 and 126 are locked together in amanner previously described and then the clutch 123 is gradually released to its normal position into engagement with the fly wheel 1, and this immediatelystarts the engine turning over. Disconnection is made in the manner already described. In the n'iodified form shown in Fig. 16, the starting motor 53 with intermediate gears is not shown. The pinion 113 which engages the gear teeth out on or attached to the iiy wheel, is normally in the position shown in dotted lines, and is carried on a shaft 116, supported by bearings 11 1. Around the shaft 116 is mounted a suitable coil with wires running to the switch points 110 and 112, as shown in Fig. 17, so that when the circuit from the battery B is closed across these two points, the solenoid is operated and the small gear wheel 113 is drawn into engagement with the gear teeth on the fly wheel. When the switch points 110 and 112 are separated the spring 117 returns the small gear 113 to its normal position.

Fig. 17 is a simplified form of Fig. 11 in which the relays 52 and 55, and switches 56 and 106 are disposed with and a special switch is used, consisting of two contact points 110 and 111 and switch blade 105). In the operation of the apparatus shown in Fig. 17, the switch blade 109 is thrown to the right. It first makes contact at 111 with an extended post. This first contact closes the circuit from battery B through the motor 53 and allows the motor to speed up. Continuing, the movement of the switch blade allows current to pass through the coil 50, which operates the clutch shown in Fig. 3. The automatic governor shown combination of an in Fi 5 is used to releasethe clutch when the engine picks up. This governor may be dispensed with and the circuit opened by means of the switch blade 109 at the time of removing current from the starting motor. Should it be desired to close the current in the clutch coil at the same instant of starting, the long contact 111 may be reduced in length to the dotted line 112, and when so constructed, a circuit is closed through the clutch simultaneously with the starting of the motor.

The form of controller and method of making connection thereto may be greatly altered from those shown. It is thus easily seen that numerous and extensive changes and alternations may be made various devices, without departing from the spirit of my invention and the scope of the appended claims.
