Application filed August 14, 1917. Serial No. 186,088-
To all whom it may concern:
Be it known that I, ETHELBERT M. FRAsnR,
a citizen of the Dominion of Canada, residing at Yonkers, county of Westchester, and State of New York, have invented new and useful Improvements in Starting and Lighting Apparatus, of which the following is a specification.
My invention relates to a starting and lighting apparatus particularly adapted for use in motor vehicles, although it is likewise ap licable in other instances as will more fu y appear from the following description. One of the objects of my invention is to 15 provide in a single unitary structure a motorgenerator set com rising a stationary field structure, a rotata 1e armature, and an independently rotatable second winding interposed between said field structure and Said armature, that can be utilized for generating electric current and used as a motor for starting automobiles.
Other objects of my invention will clearly appear from the drawings and from the detailed description to follow.
An apparatus embodying my invention is illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is aside view partly in section.
Fig. 2 is a view illustrating the manner in which my improved starting and lighting apparatus may be connected up with a gasolene engine as used in motor vehicles.
Fi 3 is a wiring diagram of my starting 1 and'lighting apparatus in connection with a starting switch, an automatic switch, a battery, lights, and horn motor. I
Fig. 4 illustrates a portion of the rotatable second winding shown in section.
In the preferred form of my device the improved starting and lighting apparatus comprises an outer stationary field structure B, an inner rotatable armature O and an intermediate independently rotatable second winding D, these three members constituting a motor-generator.
As shown in Fig. 1, the outer stationary field structure B comprises the magnet yoke and poles F, series coils and shuntroils H, constitutin one set of field magnets and coils. Secure to the magnet yoke E are the end-bells I and I, the
central portions of which are constructed so as to form hubs or bearings in which the shafts J and J, respectively, are suitably journaled.
The rotatable armature O comprises the core K, the armature winding L and the commutator M. The armature O with its commutator M is keyed or otherwise suitably secured to the shaft J.
The intermediate rotatable second winding D is made up of conductors of high electric and magnetic conductivity, so constructed and arranged as to form a single winding, provided with a commutator which is carried by the end-bell U which'is keyed or otherwise suitably secured to the shaft J. This end-bell U also forms a support and bearing for one end of the shaft The other end of the armature winding D 1;
ell
secured to but insulated from the endwhich is rotatably mounted upon the hub of the end-bell I.
In Fig. 4 I have illustrated in section a part of this second winding D in which a is the soft iron portion made up of iron laminae, and b and 0 form the copper conductors b and 0 being insulated from each other and from the iron portion a by the insulation (Z.
Suitably secured to the hub of the end-bell I are the brushes 0 for the commutator and suitably secured to the end-bell I are the brushes R for the commutator N.
As shown in Fig. 2 my starting and lighting device may be suitably secured to the casing of the gasolene engine S by means of the strap T, although if preferred it may be secured to the engine bed or to any other adaptable part of the motor vehicle. One end of the driving shaft S of the engine S is connected the shaft J while the shaft J.
gear. Such a throw-out gear may well known illustrated diagrammatically in Fig. 2,'from which it will be apparent that as the shaft J is rotated the pinion V will move forward to engage and W, thereby rotating the driving shaft engine S. In my be the 0f the rotate the toothed fly wheel improved starting and lighting apparatus the speed ratio between the engine shaft andshaft J is preferably 2- by suitable gears and chain to i may be pro-' vided with any suitable form of throw-out Bendix gear. which I have u mg or closing the heavy lines connected through the motor" winding D to the starting switch X and to thestorage battery Z. The generator shunt field coils H which are connected in shunt across the generator armature winding L are shown in light lines in the circuit of which is inserted the switch Q for automatically closing the circuit when the current has reached a certain voltage for chargin the battery Z and which will open automatically when the voltage falls below the said predetermined amount. The lights 1, 2 and 3 and horn motor 4, with their respective switches, are connected across the battery circuit.
With my improved starting and lighting apparatus connected in the manner shown in Fig. 2 the closing of the switch X will place the batter Z in circuit with the motor winding D and the series coils G. This will cause the winding D and the shaft J twlll rotate the shaft J close thereby enabling the to rotate; the pinion V will move out on its threaded shaft so as to engage and rotate the fly wheel W thereby causing the shaft of the engine S to rotate and start the engine. As soon as the engine speeds up sufliciently so that the fly wheel W causes the pinion V to rotate faster than the shaft J, the pinion V will automatically disengage thefly wheelW and the opening of the switch X will then cut out the motor winding D coils G. The continued rotation of the shaft of the engine and the armature 0. he armature (l with its cooperating field structure B 'will then actas a generator to generate current. When this current has reached a certain voltage the switch Q will battery Z to be charged. If the voltage generated by my device should fall below the predetermined amount then the switch Q will open thereby protecting the battery Z from any discharge. it an apparatus and system arranged in accordance with my invention the battery Z may be utilized for operating incandescent lamps in the various lights 1, 2 and 3 of the motor vehicle, or for operating the What I claim is:
