of Michigan, have invented certain new and useful Improvements in Electric Starting and Generating Mechanism for Vehicles, of

which the-following is a description. The invention relatesto a devlce which may be applied to a liquid hydro carbon or gas engine and may be utilized in connection with said engine for startingthe same and for maintaining, after being started, a suitable supply of electrical energy by which it may be actuated and by which the ignition and lighting systems of any desired form may be supplied with current.

The obj ect of the invention is to provide a simple and compact device which may be applied directly toan engine and will provide a means for initially starting-said en- 'gine as well as a means for storing energy for the ignition circuit of the engine and such other circuits as desired.

A further object is to provide a dynamo electric machine'forstarting an engine and so arranging its various parts that. it may be utilized in'connection with the timeshaft which distributes the current to the various cylinders of the engine. I

A still-further object is to provide an arrangement by which the variousdriving and driven sliafts will be automatically coupled and uncoupled to give the proper driving relation from the dynamo electric machine to the engine-and from the engine to the dynamo electric machine, I

Fig. 3 is a side elevation partially in section of the dynamo electric machine as illustrated in Fig. 1.

. Fig. 5'i s a detail view of a ratchet clutch such as employed. Fig. 6 is a diagrammatic It has heretofore been common practice to employ a magneto geared to the engine magneto devices have been utilized in conjunction with storage batteries so that the generator might directly act in the ignition circuit or might act to store energyin the storage battery from which the proper currentfor the ignition circuit might be derived. a

It is one of the principal objects of the mechanism so applied to the magneto shaft which-is, as ordinarily used, such that by suitable connections, the dynamo electric machine may be utilized in conjunction with a source of-elec'rical supply to start the engine. Said engine when once started will I in turn drive the dynamo electric machine as a generator and current derived from such a drive is utilized in the ignition circuit and may be used in lighting or other cir cuits. As illustrated herein, the armature of the. dynamo electric machine is illustrated as geared to the engine shaft which in turn has suitable gearing connections with the i timing device by which the current is distributed at proper intervals to the various cylinders of the engine. Such an arrangef ment is not absolutely essential to the invention but illustrates av very compact and direct means of connecting the various parts in proper driving relation.

denotes an engine of the liquid hydro-carbon ,type and is shown as of the four-cylinder I type which has a main crank shaft 2, and a clutch 3, by which it may .be connected to "the mechanism to'be driven. It is of the automobile type of well-,lgn otvn form and thelmechanism hereinafter"described is par- 5 with an engine of this type inasmuch as it permitsstarting the engine at will and supplying necessary current for ignition and lighting purposes. p

' At the forwardend of the engine there is a casing 4, which contains a, train of gears 5, 6, 7, and 8. The gear 6, drives the fan 9, gthrough a suitable connecting belt 10. The gear 7-, is upon the cam-shaft 11, which f actuates the valve mechanism of the engine.

The gear 8, is upon the main shaft 12, of.th e view illustrating thegenrirl wiring circuits.

, generating device -which shaft, through jspiral gears, 13, 14,- drives the time-shaft 15, and actuates a suitable timing device mount fed thereon and not specifically illustrated in the-drawings. Bolted tothe frame of the present invention to provide a compact Referring to the drawings, the numeral 1,

I ticularly well adapted for-use in connection .to provide'bearings for the main shaft 12,

and intermediate driving and driven shafts hereinafter described.

The armature'18, of the dynamo electric machine is arranged in a vertical position within the field-coils and has a downwardly projectin shaft 19, provided with an antifriction t hrust bearing 20, at its lower end. Adjacent to the armature-core is arranged a gear 21, of the spur type, which meshes with a gear 22, also arranged on a vertical axis upon a shaft 23, and provided with a thrust bearing 24, both of the gears 21, and 22,-have arranged adjacent to them antifriction bearings 25, 26, which are located in a section 27, of the casing 16.

The shaft 19, has adjacent to its lower end a worm-gear 28, which meshes with a wormgear 29, secured to the main shaft 12, in such I I ratio that rotation .of the armature will rotate the shaft 12, at comparatively slow speed and will, through the train of gearing'5, 6, 7, 8, turn the main shaft of the engine for the purposes of starting it.

Between the gear22, and its shaft 23, is arranged a roller-clutch 22, of the ratchet type such as-illustrated in 'Fig. 5 and with its teeth so arranged that it will slip with reference to the shaft 23, and will communi= cate no motion when the gear 21 is rotating and the shaft 19 is driving the engine shaft 2 through the main shaft 12 and gears 8, 7, 6, 5. The shaft 23, is provided with a spiral gear 30,-which meshes with a cooperating spiral-gear31,arranged upon the section 32, ofthe shaft 12. s

Appurtenant to the gear 29, there is a similar clutch 33, arranged in the hub of said gear 'asillustrated in general view in Figs. 3 and 1. The teeth of this ratchet clutch are so disposed that as the armature rotatesin one direction under the impulse of 4 current supply thereto and is operating as ainotor, the clutch 33, will bind the gear 29,

titsshaft and thereupon the shaft 12 and ;'train of gearing 5, 6, 7, and 8, will turn'the engine-shaft 2. As soon as the engine has been started in this manner and speeds up,

thelclutch 33, will become inoperative per- Initting the shaft 12, to run away from the gear 29. As soon as the shaft is thus speeded up, the clutch 22, will become effective and thereupon the shaft 12, will, through the s iral ears 31, 30, and spur- gears 22, 21, I rive ;tfiearmature-shaft 19, so that the dynanid} electric machine will be operated as a generator and "will generate current for storing electrical energy and providing circuitsused in conjunction with the-engine.

It will be noted that with the worm-gear drive through the gears 28, 29, and the train of gears 5, 6, 7, and 8, a great advantage of coil a, of an induction coil moses/a leverage is secured from the dynamo electric machlne operat ng asa motor to the engine shaft. With the spiral gears 30, 31, and

spur gears 22, 21, it is apparent thatthe armature shaft will be driven atcomparatively high-speed when the dynamo electric machine is operating as a generator and is being driven from -the engine shaft. either case it is apparent that whether the dynamo electric machine is acting as a motor to drive the engine shaft or acting as a generator being driven by the engine shaft, the shaft 12, will drive the spiral gears 13, 14:, and maintain action upon the timing device or distributing device, so that the ignition circuit will be properly timed for the several cylinders. In order toreduce friction'an anti-friction thrustbearing 34, is provided at the end of theshaft 12," to take up the thrust of the spiral gears and an antifriction thrust bearin 35, is provided at the lower end of the sha t 15; i

In order to clearly show the operation of the mechanism the several elements are diagrammed as illustrated in Fig. 6, wherein the several parts already referred to arealready designated by corresponding ,.refer-. ence characters. In this diagram B','indicates the storage battery or accumulator having terminal leadsv 50, 51, which arecon-,, nected respectively through switches 52, 5 3, with a lighting circuit 54, 55, and a main circuit 56, 57, which is electricallyeonnected'- with the dynamo electric machine 17, and is; also connected with the ignition circuit as.

hereinafter defined. One leg of the circuit 57, is grounded at the common ground G,

which may be the motor casing and .the leg 56, leads through the conductor 58, to the movable contact 59, of a make and break device. The stationary contact .60, thereof is connected through a lead 61, with a primary ounded as at G, while the secondary coil a, through a lead 62, is connected with a movable or zro'tary. '111) member '63, of the distributing device C. The stationary contacts 64, 65, 66, and 67, through leads 68, 69, 70, 71,. are connected with the insulated terminals of 'thes arkplugs 72, 73,74, and 75, of the-severe. cylinders of "the engine. It is understood that the cooperating contact of hese spark ugs is grounded to the common ground ang 'the plugs are not shown herein in detail asfi iey are well-known in the art Obviously, the switches 52,53, may be located withinready reach oftheoperator'so that as the switch}5.8,

is: closed, the electrical supply B,,is connected to the dynamo electric machine 17 ,-to

- drive 'saidmachine 'asa motor. Thereupon,

through ,the gearing heretofore described, the enginesh'aft will be turned and the.initial impulse will be given to the main shaft of the engine-inasmuch as the timing or distributing device will be actuated and the relation one with fthe 'other, a simple ar-.

- a main shaft extending therethrough, an armight be varied to a considerable extent withoutdeparting from the spirit or intent of the invention and various forms of gear-- ing might be utilized in place of the specific.

worm and spiral gear arrangement herein described and shown.- It is preferred to use a differentially wound motor so that it is possibleto maintain a proper current condition when the dynamo electric machine is operating as a generator and which will operate properly as amotor when under the influence of the current from the battery B. Various switches might be interposed in the circuits for controlling them in any desired range-ment being herein shown in diagram.
