To ctZZ whom it may concern.-

Be it known that we, ALBERT DE DION and GEORGES BOUTON, citizens of France,and residents of Puteaux, in the Department of the Seine, France, have invented a new and usefullmprovement in Igniting Devices for Gas 1 or Like Motors, (for which we have obtained Letters Patent in Great Britain, dated October 21, 1895,No.19,735; in France, dated September 13, 1895, No. 250,259; in Germany, dated October 28, 1895, No. 87,352, and in Switzerland, dated October 17, 1895, No. 11,033,)01": which the following is a specification.

This invention consists in the arrangement of devices for igniting explosion engines which will allow of the following advantages: First, a contactmaker or circuit-closer similar to those used with an ordinary inductioncoil can be placed at any desired distance from the coil, and its movements to establish and disestablish the circuit of the primary of the induction-coil may be effected by mechanical means at the exact moment when a spark is required for igniting the explosive mixture of a gas1notor; second, the proper movements of the circuit-closer may be so produced that they will complete the circuit while the motor is turning at its normal speed or at a lower speed, but will be inoperative if the motor is turning too quickly, thus taking the place of a speed-regulator. To obtain these results We employ apparatus such as is shown diagrammatically in the accompanying drawing, in which the figure shows the essential parts of a gas-engine and illustrates our invention combined therewith.

Referring to the drawing, the reference-lettor A indicates the crank-chamber, and B the cylinder, of any ordinary gas-engine. At any suitable point relatively to said engine we place an induction-coil O, the primary coil of which is supplied with current from a battery or other source of electric energy D. At whatever point the coil Ois placed wires to and Z) are led from the terminals of the primary coil to binding-posts c and cl, in one of which a contact-point e is mounted, while from the other a vibratory strip or circuit-closer E is mounted in such manner that it lies very near 7 the extremity of the contact-point 0, beyond which said strip extends for some little distance, a shoe F being mounted upon its free or unsupported end. In suitable relation to said shoe F is a disk G, mounted upon a shaft H and provided at one point in its periphery with a notch f.

The shaft H is revolved by any preferred means. 7

The arrangement of the parts is such that as long as the shoe F rests upon the periphcry of the disk G the conducting-strip E will be held out of electrical contact with the extremity of the contact-point 6. shoe F falls into the notch f, however, the elasticity of the circuit-closer E causes it to come into contact with the point e, and the circuit of the primary of the induction-coil O is thereby completed for a moment or until the continuous revolution of the disk G causes said shoe to be lifted out of the notch. Thus a current of high tension is induced in the secondary of the induction-coil O. The terminals of said secondary coil are connected to two binding-posts K and L, and from said binding-posts wires M and N are led to and into the combustion-chamber or explosionchamberB, within which the extremities of said wires are brought close together, the interval of separation between their ends being such that the high-tension current will readily jump across. In passing this interval of separation a spark is produced, having ample igniting power to produce an explosion of the gas or gaseous mixture.

The flexibility of the circuit-closer E and the outline of the notch f may be so regulated that if the motor turns too quickly a suflicient movement of the circuit-closer to bring it in contact with the point 6 cannot be obtained, since the shoulder f of the notch f will come into contact with and arrest the circuitcloser before a full movement can take place, thus preventing contact with the point 6. With this arrangement the current is only used during the time of explosion.

Having thus described our invention, what we claim is- 1. A gas-igniting apparatus for a gas-engine, consisting of a vibratory conducting-strip or WVhen the circuit-closer having a shoe, a conducting contact-point, Wires connected to both and to the terminals of the primary of an induction-coil, and a notched disk upon the periphery of which the shoe of the circuit-closer rests out of contact with the point, and at each revolution falls into the notch an d closes the circuit of the primary of the inductioncoil, substantially as described.

2. In explosionnnotors a device for igniting the explosive mixture by electricity consisting" of a notched disk revolved by any suit able means, a circuit-closer having a shoe resting on the disk and falling at each revolution into the notch, a contact-point close to but out of contact with the circuit-closer save when the shoe thereon passes into the notch in the disk and an induction-coil having the terminal of its primary connected to the circuit-closer and contact-point and the terminals of its secondary slightly separated in an explosion chamber, substantially as de scribed.

In testimony whereof We have signed this specification in the presence of two snbscrih" ing Witnesses.
