MEANS FOR STARTING MOTOR ROADVEHI0LES.

Specification of Letters Patent.

Application med my 14, 1913. Serial No. 772,914.

neto of which has two pairs of pole-pieces,

betweenone of which there rotates an armature for generating lighting current, and between the other'pair'of which there rotates an armature for generating ignition current.

Now, the object of my present invention,

is to provide means whereby this machine can be utilized as a motor for starting motor road vehicles, and to this end 'I employthat armature of the machine which is used for generating the lighting current as a motor, current bein supplied thereto from the usual accum ators and the rotation thereof being transmitted to the crank-shaft of the vehicle motor through the medium of suitable gearing. In the case where the lighting armature is driven directly from the ignition armature of the double armature magnetoelectric machine,- the transmission between the two armatures may be of the free-wheel =type,'so that the lighting armature can be driven from the accumulators as a motor for purposes as above described, without. afl ecting the ignition armature which remains inoperative until it is driven by the petrol motor in' the usual manner.

To enable my invention to be fully understood I' will describe it by reference tothe accompanying drawing, in which:

Figure 1 is a sectional side elevation of a magneto-electric machine of the kind described in the specification of application Serial No. 679044, provided with the means for starting according to the present; inven- 'tion. Fig. 2 is a diagrammatic view illustrating the connections between the magneto machine and the accumulators as hereinafter described. Fig.3 is a detail view' showin part of themagneto illustrated in Fig. 1 and same with the cam shaft and crank shaft of an engine. Fig. 4 is a detail .view showing the arrangement of the gearing and illustrating the free wheel clutch mechanism.

illustrating one method of connecting the armature c is mounted upon the spindle e and is driven from the spindle (I through the medium of the-toothed wheels d" and'e, the

wheel d being connected to the spindle (1 through the medium of a tree-wheel clutch. I

The spindle e of the lighting armature-o has mounted upon it the free-wheelsproc'ket wheel f which is in connection by means of a chain, with a sprocket-wheel upon the crank shaft of the engine or a shaftdri'ven' i thereby. v w

The lighting armature c is in electrical connection, as shown in Fig. 2, with a secondarybattery or set of accumulators g, the

circuit-containing the double poleswitch hf by means of which it can be broken. or. made as desired.

.JWith this constructio it will be obvious that whenthe internal combustion engine is running normally, the spindle d 'iS driven soas to rotate the armature b and through. the medium of the toothed gearing 'd, e, the armature 0, thus providing both current for the ignition of the explosive'charges in the engine and lighting current from the armw' ture c. When, however, itis desired to e'm-f ploy the magneto -machine as a Irieans- .f 0r starting the internal combustion engine then the circuit connectin the armatureo with the batter g is made y means of the double pole switch a is rotated so that the spindle e is revolved, the armature b, however, remainin' in'operative by reason of the free-wheel clutch connecting the spindle d and wheel 0!. The.

h, whereupon the-said'armature rotation of the spindle .-e revolves the sprocket-wheel the motion of whichiis transmitted to t e crank-shaft of 'the engine which is thus started. Assoon as the said crank-shaft is set in motion and the/engine started the spindle d of the ignition arma 'i-ur'e 'b' is also rotated whereupon the neces-f sary'cuirent for ignition sparking is -pr vided'. a

In Figs. 3 and 4; I have shown one ar-- -rangement for connecting the magneto hereinbefore described with the cam shaft and crank shaft of an explosion engine, the parts of'the'magneto being-letteredas in Fig. 1.-
