To all whom it may concern "v Be it known that I, JOSEPH BIJUR, a citizen of 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 full, clear, and exact description, such as will enableothers skilled in the art to which it appertains to make and use the same.

This invention relates to engine-startmg 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 p'rime mover incapathe above type in which the lsource 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 features of construction, combinations of 'in part pointed out hereinafter.

is wholly inde endent of electric currents.

Another ob]ect is to provide a compact arrangement of parts wherein centrifugal force acting upon suitably disposed masses is utilized to unmesh a gear and pinion connected respectively with the engine and the starting motor;

Another object is to provide aisimple anddurable starting apparatus of few parts, inexpensive to manufacture, easily assembled and eiiicient in action.

Other objects will -be in part obvious and The invention accordingly consists in the elements and varrangement 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.

In the accompanying drawings, wherein are shown one or more of various possible embodiments of the vseveral features of the invention,

Similar reference characters refer to similar parts throughout the several views of the drawings.

By way of explanation, i-t may be stated that the present invention is directed, in some of its -more specific features, to the starting of automobile engines simply by the depression or other movement of a single hand or foot operated lever without requiring the drivery to leave his seat. The need for a .device of this sort, which is not only reliable and quick acting, but also inexpensive and to a certain extent automatic, has been felt for a number of years. It is necessary, for a starting apparatus to be successful, that it b e readily applicable to automobiles no'w inA use at a minimum cost of installation and without requiring the services of a hligh -priced mechanic or electrician. Furthermore, the apparatus must be Capable of performing its cycle of operations a considerable number of times withoutmaterially dralning its source of energy,

. such asastorage battery, which is neceavrily of limited Capacity. As the description progresses, 'it will be seen that. these requirements have been fullymet and that an apparatus is provided in which the required standard of excellence has'been attained.

Referring now to the drawings, and more i particularly to Fig. 1, there is shown at 1 a member, suchas any-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 4 of an electric or other Inotor 5. Inasniuch 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 ield 6 and .armature 7 in series with eachotherl the pinion 3, as by the retaining bolts 16,

f v which pass respectively,7 through the slots the radial displacement of the members or weights 15 through the connections at the` are the slotted projections 17 corresponding in numberftothe number of leaf springs 13 18 in these projections. In the embodiment illustrated in Figs. 1, 2 and 3, the projections not only serve the purpose of limiting slots .18 with the leaf springs 13, but p I'ovide at the shoulders 19 suitable surfaces for contacting with thc washer 10, provided, as above indicated, to limit the leftward travel vof the pinion 3 and its associated parts. Y f

When the' starting apparatus is not in operation, the parts are locatedas indicated in Fig. 1, with 'the pinion 3 disengaged from the gear 2 and the weights 15 firmly press-ed inwardly againstthe l'cylindrical extension 20 of a horizontal shaft 21 reciprocable'by the hand or'foot operated rod 22 acting in con]unct1 on with the spring 23 and belli. crank lever 24, the spring 23 tending, as

will be obvious, to force upward the rod 22, which for convenience will. be termed the.pedal. From this it will be clear that the downward movement of the pedal 22 in opposition to the spring 23 will cause the counter-clockwise rotation of `the bell- Vcrank lever 24, which' in turn, through the pin-and-slot connection at 25, will move the 4 3 rotate slowlv.

horizontal shaft 2l toward the right, andy since the weights 15 are firmly pressed in- `ward against the reduced extension 20 of this shaft, the movement of the shaft to-` ward the right will cause at once an engagement of the weights 15 with the shoulder 26 and the pinion 3 will move toward erted by the coil spring 9, the relative proportions of blade springs 13 and coilspring -to set itin slow rotation, the pinion will turn suiiiciently to insure meshing with the teeth of thegear as Soon as the former has moved suliiciently far toward the right. A preferred means for supplying such a current to the motor at this time is illustratedin Fig. 1 as comprising the main switch 8 whose movable contacts 27, 28 are mounted directly onthe horizontal shaft 21, above described. As indicated in Figs. 1, 2 and 3, a slight movement of the shaft 21 is suiiicient to establish an electrical connection between the movablecontact 27 and the fixed contacts 29, 30, thereby completing a circuit from the` posit-ive side of the battery4 31 through the armature 7 -and field 6 of the motor, starting resistance 32. fixed contact 29, movable contact 27 and fixed contact 30 tothe negative vside of the battery,l vand as a result tue armature 7 and" pinion The continued movement` toward the right of the horizont-al shaft 21 causes the engagementof gear 2 and pinion 3 and almost immediateliv thereafter the starting resistance 32 is short-circuit-ed by virtueV of the connection between the movthe gear 2 in opposition to the force exable contact 28 and fixed contacts 33, 34

of the ,main switch 8, as clearlyI illustrated in Fig. 2 of the drawings. The motor windings are now sufficiently energized to set in rotation the fly-wheel 1 and the engine. A

and as soon as the latter begins to rotate under its own power, the centrifugal force acting upon the weights 15 benomes suiii- `cient to move them outward in opposition to rest in the position illust-rated in Fig. 1.

If, however, the pressure is not removed `from the pedal, the motor will rotate at its free running speed, consuming little power and having no effect whatever upon the engine, since the pinion can not be re-meshed with the gear while the lpedal is depressed. Then when the pedal 22 is allowed to rise, the motor comes to rest with the parts as shown in Fig. 1.

Inorder to prevent the downward movement vof the pedal when the engine is rotating, arsuitable interlock may be provided, this mechanism comprising, in the present instance, a voltage coil 36 (Figs. 1, 2,y 3 and 5) connected acrossthe terminals of the 'generator 37 driven by the engine, this coil, when energized, attracting in opposition .to the spring 38 the armatures 39, 40," secured respectively to the two'halves 41, 42 of a split collar, thereby bringing the two hinged members of this collar into `the annular groove 43 of the pedal 22, the

groove and collar registering when the pedal 1s '1n its normal position of rest, indicated lin Fig. 1. It will be obvious, without further elaboration, that as long as the voltage coil 36 is energized, it is impossible to depress the pedal, 22 so that energy can not be supplied to the motor 5 until the engine has come to rest.

In the several figures of the drawings Iwhere the generator 37 is illustrated, Van Fautomatic Vswitch is shown, more or less conventionally, as comprising a 'current coil 44 and a voltage coil 45 wound so as to as,-

- sist the current oil in maintaining a closed circuit at the contacts 46, the switch being opened by reversecurrent through the' current coil Iand closed whenever the voltage coil is suficiently energized. The generator is illustrated for convenience as a shuntwound machine without a voltage or current regulator, Ait being understood, of course, that a suitable regulator is in practice provided and that the present invention is applicable to anydsuitable type of generator,

. regulator and automatic switch.

In Figs. 6, 7 and 8 is illustrated another embodiment of the present invention. As before, a pedal 22 is provided together with a spring 23bell-crank lever 24, interlock 35,

main switch 8, fly-wheel 1, gear 2, motor 5 and reciprocable pinion 3 feather-keyed oii the pedal 22 is depressed, thereby moving toward the right the horizontal. shaft 50,

= collar 48 and switchA rod 51. One or more of the weights 47 may at this time tend to buckle outward, but evensif both the weights should buckle outward, the collar 48 coming soon into engagement with the left end of the coil spring 52 would, through f this comparatively stilil spring,y effect the movement of the pinion 3`towardthe gear 2. As before, connection is made at the auxiliary contacts 29, 27, 30 of the main switch 8 to set the motor in slow rotation prior to fly outward and thereby disengage the pinion 3 from the gear 2 even though the pedal 22 remains depressed. Premature rengagement is prevented by the continued rotation, at high speed, of the weights 47 as long as the pedal is depressed, since the upward movement of the pedal by denergizing the motor only after connectionV 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 the motor shaft 4, the generator 37, auto# maticswitch 46 and main switch 8 are pro- -vided, as in Figs. 1 to 9, and the pedal 22,

electro-magnetic interlock 35 and bell-crai`ik lever 24 serve, as in the previous figures, to illustrate a suitable way of operating the main switch 8 and other parts. of the mechanism. In the present embodiment ofy the invention ,the pinion 3 is feather-keyed, as before, upon the shaft 4 of the motor, but the spring 53 tending to throw this pinion out of mesh with the gear 2 is mounted within the motor shaft instead of around the same, as in Fig. 1. The two arrangements of spring are, for`the purpose of the present invention,` interchangeable. The face-plate 54 secured, as by the screws 55 to the outer end of the pinion member 3, serves to retain on said member the annular member 56 feather-keyed as at 57 upon the pinion`member 3 and comprising parallel ange portions 58, 59 suitably secured together, as at 60, in such a way as to exclude dust, and carrying between them the weighted levers 61 pivoted, as at 62, to trunnions mounted in the two flange members 58, 59. These weighted levers, as

. illustrated more in detail in Fig. 12, are

fastened .together at their freev ends by a coil spring 63, against the retractile force of which the weighted levers move radially outward to an extent proportional to their interlock 35 prevents'the downward move- Aiio speed of rot-ation. When-the' weights are at l rest, or rotating below a predetermined speed, the. inwardly projecting lugs 64 thereon press inwardly against the outer surface of the pinion member y3, and if the annularmember 56 is in the position illustrated in Fig. -these lugs register with and embodiments heretofore described, with the l result that `first the auxiliary contacts 27, 29,

y l30 of the main switch are closed, thereby setting the motor 5 in slow rotation; second, the bifurcated operating lever 68 moves the annular member 56, and through the lugs 64 thereof, the pinion member 3, toward the right from its dotted-line position in Fig. 10

a suicient distance so that the slowly rotatv ing pinion comes int'o mesh with the stationary teeth 2 of the fiy-wheel; third, the continued downward motion of the pedal closes the main contacts 28, 33, 34 of the main switch 8 atthe time the pinion 3 has come completely7 into mesh with the gear 2, as

illustrated in solid lines in Fig. 10. The motor is now energized suiiiciently to enable it to set the engine shaft in rotation through pinion 3 anda gear 2, and as soon as the engine begins to rotate under 'its own power the outward movement of the weighted levers 61 causes the inwardly Vprojecting lugs' 64 thereof to pass out of theannular groove 65 on the pinion member 3. This removes the only obstacle to the leftwardv movement running speed, which should, of course, be

of the pinion member under the influence of the coil spring 53 within the motor shaft.

The pinion member therefore promptly slides toward the left, out of engagement with the gear 2 of the fly-wheel, as illus- -trated in Fig. 11, the axial travel of the pinion member being limited by the length of the slot thereof in coperative relation of thepin 71 on the motor shaft. This disengagement of gear and inion, it is noted, is wholly independent o the position of the pedal 22 and bell-crank 24. After disengagement has occurred, if the pedal be still depressed the motor will rotate at itsfree low enough for safety, as a no-current release might otherwise need to be added to the apparatus. When pressure on the pedal is released the retractile spring 23 restores the bell-crank lever 24, main switch 8 andl bifurcated operating rod 68'vto their initial positions, thereby disconnecting the motor from the source of power and moving the annular member toward the left into the poi 35 serves as before, to lock the pedal 22 in its raised position whenever the 'engine is run-` ning.

It will be apparent from' thel drawings l that with this embodiment of the invention a combination of elements especially Ladapted for engine-starting is provided within a small compass at a minimum cost.

Briefly stated, the operation of the embodiment illustrated in Figs. 1, 2 and 3 is as follows IVhen the engine is to be started, the pedal 22 is depressed, thereby slowly rotoward the gear and then sending a heavy ltating the motor while the pinion 3 is moved current through the motor as soon as engagement between gear and pinion has been effected. lVhen the engine has started,'the high speed of rotation of the weights 15 causes them to slide outward over the end of the shoulder 26, whereupon the coil spring 9 causes the pinion 3 to move toward the left, out of engagement with the gear 2. Then as soon as pressure is released from the pedal the motor comes to rest. The electro-magnetic interlock 35 connected across the terminals of thegenerator 37 locks the pedal in its raised position and prevents the engagement of gear andpinion when the engine is rotating. In Figs. 6, 'Z and 8 disengagement is effected by the outward movement of the weighted links 49 connected respectively to aV pedal-controlled lmember 48 Y and to the pinion 3. When the pinionris moved into engagement with the gear, the

coil spring -r52 transmits power from the member 48 to the. pinion 3' in case all the weighted links 49 should buckle. In Figs. 10 to 13 the weighted levers 61 are provided with inwardly projecting lugs 64 which, at

a predetermined speed of rotation,.pass out' Y of the annular groove 66 on the pinion member 3 and permit the latter to be disengaged from the gear 2 through the force exerted by the expansile spring 53 within the'motor shaft. In lall the figures the movement of the pinion toward the gear, as well as .the

operation of the starting switch, `is accom-` plished directly through the single hand or foot operated rod 22. y

It will thus be seen that there is provided apparatus in which the objects enumerated are achieved and other advantageous ends attained.

In the above description certain expressions, such as left, right, clockwise and counterclockwise, have been used to designate simply the relative locations and relative movements vot cooperating parts, and it will be obvious that these words are neither used in an absolute sense nor intended in any way tov illustrate the arrangement of the specific expressions employed.

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.
