MAGNETO IGNITION DEVICE.
Specification of Letters Patent.
Application filed January as, 1913. Serial no. 743,708.
To allwhom it may concern Be it known that we, Dr. FRITZ Scrmo'rnn, chemist, and FRANZ L. Miinnsn, engineer, subjects of the German Emperor, and residents of' 4 Duisburgerstras'se, Wilmersdorf- WVilmersdorf- Berlin, Germany, respectively, have invented certain new and useful Improvements in Magneto Ignition Devices, of which the following is a specification.
The present invention relates to. a starting device for multi-cylinder combustion engines by means of the simultaneous interruption and reversal of a directcurrent.
The essential feature of the invention consists in an arrangement for sending the current from a suitable source of energy through the armature winding of the magneto in alternating directions. The possibility of utilizing the armature winding, which in the newer magneto is provided ,with primary and secondary windings, for the purpose of generating currents induced from the low tensioned primary winding into the high tensioned secondary winding is possible'when the motor is started.
The current for starting, which naturally is'the direct current, must be, for the above" mentioned purpose, converted into an alternating current by means of constant alternation of the poles. The magnetic field of the magneto employed is not weakened thereby as .would be the case if a pulsating current were made to flow in one direction only through the primary winding of the armature.
The object of the invention is more clearly illustrated in the drawing in which-'- Figure 1 shows one form of the invention in which an electro-magnetic interrupter of 2 shows a device serving for the same purpose provided with a mechanically actuated switch and two individual alternately employed sources of current, and Fig. 3 shows a device employing the electromagnetic interrupter shown in Fig. 1, in combination with the two individual sources of current shown in Fig. 2.
A resilient push-button a 'serve's for the operation of the device illustrated'in Fig. 1. The armature b of the interrupter is in the form of a double armed levei, one side-.of which may be depressed by the push-lmtton a. The two arms of the armature b are subjected to the influence of the insulated springs c, c, which hold the lever in a horizontal position. If the lever 7) is depressed by means of the pushbutton a, the circuit of the battery d, or other suitable source of energy, is closed at the right hand'side in such a manner that the current flows through the contact screw f, the contact g, and the bridge in to the frame or ground. The current from the other pole of the battery flows over the lever I) and through the primary winding of the magneto h by way of contact 2', and contact screw is, hand side of the double armed lever b. The circuit is thereby closed as the other end of Patented July 28, 1914:- y
at the left the primary winding of the magneto is connected to the frame or grounded. However,
only the armature upon the left hand side of the lever 7) is attracted by the electro'magnet 0. The lever then tilts toward the left, and the current passes over the left side directly to the frame and the electrical connection with the primary winding is established upon the right hand side of the lever in a manner similar to that described with respect to the left side. The process is repeated over and over again. The primary winding of the magneto is therefore traversed continuously in this manner by oppositely flowing impulses.
The interruption and the reversal of the current. actuated by an electromagnetic device asshown in Fig. 1, may be replaced by a commutator actuated mechanically or by means of a crank manipulated by hand, or the like. The modification of the invention shown in Fig. 2 accomplishes the same result by dividing the battery into halves,
which may be conveniently done especially with dry cells. Two batteries of equal capacity are employed which are combined into an aggregate as a matter of expediency. Figs. 2 and 3 illustrate the execution of this idea by way of examples.
In Fig. 2 the positive pole of the battery 5 is connected with contact 1 and the negative pole of battery 6 is correspondingly connectedwith contact 2. Reference character 3 indicates the primary armature winding of the magneto, one end of Which is connected with the frame. The other poles of'the battery are also electrically connectedwvith the frame. If the lever 4 is shifted mechanically so that it contacts alternately with Contacts 1 and 2, the armature ing current.
In Fig. 3 a device, similar to that shown in Fig. 1, 15 shown operated electro-magnetically. Reference-character 4 indicates an armature associated with two electromagnets 7 and 8 The condensers 9 and 10 are situated in parallel to the Points of interruption. If it is assumed, for instance that the armature 4 rests upon 1, then the battery 6 would be placed in circuit. The current then passes from the positive pole of battery 6 to the frame, from there through themagneto winding 3 and rein-inns by way of 4, 1, 8 to the negative pole oi battery 6. The electro-magnet 8 becomes energized consequently and attracts 4. The current of the battery 6 is now interrupted, but battery 5 is simultaneously switched on and its current now flows in the opposite-direction through the magneto winding, namely from the positive pole by way of 7, 2, 4, 3, to the frame and from there returns to the negative pole of the battery The electro-magnet 7 becomes energized, attracts 4t and rcstablishes the initial state, and the same process begins anew and continues until the circuit is broken manually at a" suitable point, for instance between 4 and The primary circuit of the magneto is also traversed by the alternating current? means for causing the current from said' source to flow alternately in opposite directions through said primary winding.
2. In a magneto ignition device-of the class described, the combination with the primary winding of the magneto of a battery, said battery being divided into two parts one of the poles of each part being grounded and the other poles being electrically connected to contacts, said second mentioned poles being of opposite polarity, and means fonalternately connecting said contacts to one terminal of said primary winding, the other terminal of said winding being grounded.
In testimony whereof we have hereto afiixed our signatures in the presence of two witnesses.
