I IGNITION SYSTEM FOR EXPLOSION-ENGINES.

Specification of Letters Yatent.

Patented Apr. 9, 1918.

Application filed August 22, 1916. Serial No. 116,283.

To all whom it may concern:

Be it. known that l, HENRY A. Lyon, a United States, residing at Solomon, in the county of Dickinson and State of Kansas, have invented certain useful Improvements in lgnition Systems for Explosion-Engines, of which the following is specification, reference being bad therein to the accompanying drawing.

This invention relates'to improvements in circuit. closers and is more particularly minptcd to control the ignition system of internal combustion engines. To this end I provide :1 switch which is operated manually to connect the spark plug ignition for energizntion but which, when released, will autonmtically disconnect the same and connect the make and break ignition, operating in conjunction with the jump spark ignition of the engine.

In the nccompanyin drawings:

Figure l is :1 top p on View of the complctc switch, the electrical circuits bein in diagram. heavy lines indicating the fiow of current when the jump spark ignition is energized.

Fig. 2 is of Fig. 1.

Referring a cross section taken on line 2--2 to the drawings, the numeral 5 designates the switch casing which is made in the form of a cup-and preferably of insulating material.

Mounted within this cup are two sets of metal contact strips 6 and 7. the strips 6 being connected through the binding posts 8 with the make and break ignition system, to be hereinafter explained in detail, while the strips 7 are connected through the binding posts 10 in the jum spark ignition system designated generally by the reference numeral 11.

Mounted within the cup is a bar or rod 12, whose terminals are seated respectively in the socket 13 and the opening 14 of the cup, while the flattened apertured portion 15 thereof receives the bolt or screw 16 which rigidly secures the same to the bottom of the cup.

The switch member 17 is made from a 'single piece of material and comprises the in tel-mediate port-ion 18 having the elongated slot 18 which for the bar, while the two depressed contact shoes 19 and 20 are disposed to resiliently engage either of two pairs of the respective contact strips 6 and 7, either the first and surrounds the attaching screw third or the second and fourth contacts (it being noted that the span of these depressed contact shoes is such as to connect two contact strips and bridge over a third contac strip), to form a closure to either one of the ignition circuits.

The upwardly projecting terminals 21 and 22 of the switch have apertures 23 and 24: which fit slidably upon the cylindrical terminals of the bar, while disposed upon one of the terminals of the bar and against the wall of the cup adjacent the socket thereof. is a coil expansion spring 26 which normally holds the switch in contact with the first contact strips 6 and 7.

The wiring system of my invention will now be described. From, one side of battery 5' leads a wire 9 to the switch member 4 from which leads a wire 1' connected to the first contact strip 6. The first contact strip 6 and the third contact strip 7 are bridged by the switch member 17 and connected to this third contact strip 7 is a wire 13 lead ing to the make and break system 30 of the engine frame, thence current flows by way of the wires 12 and wire 11' to switch member 10' and thence by way of lead wire 9 back to the other side of the battery. Thus when the switch member 17 connects the first and third contact strips, after the engine shall have been initially started'and the switch member 17 has just been released from the tension of spring 26, the current will flow by way of the first and third contact strips, and the engine frame to both sides of battery 5' and consequently ignite the charge within the cylinder. and keep the engine running. The second and fourth contact strips are also adapted to be connccted by switch member 17. The wire 9 leads from one side of the battery 5 by way of wire 17' to second contact strip 6, and a wire 16' leads from the fourth contact strip 7 to the primary circuit, of the coil box .15; thence a wire 18 runs from coil box 15 to wire 11 which conducts current by way of switch 10' and wire 9' back to the other side of the battery 5'. Thus to initially start the engine the switch member is manually pressed against the tension of the spring 26 so as to bridge the second and fourth contact, strips and be held out of contact with the first and third contact strips; there upon the battery circuit to the primary coil will be closed, and :1. hot spark generated in the secondary coil which is connected by the wire 14 to the spark plug 3 whereby the charge will be ignited.

What-I claim as new is:

1. In a device of the character described, in combination a cup-shaped casing, four metal contact strips arranged in two series and in parallel relation, a bar having its opposite terminals fixed against opposite points of the wall of said'cup, the intermediate portion of said bar being flattened and formed with an aperture, a metallic switch member consisting of an intermediate portion formed with an elongated slot and at opposite ends with depressed contact shoes arranged to connect in contacting relation the first and third, or the second and fourth of said contact strips, said switch member also formed at opposite ends with upwardly projecting terminals having openings through which said bar projects, a screw bolt extendin vertically from the bottom of said cup an projcctin through the aperture of said bar, a nut is readed on the upper end of said bolt and engaging the flattened portion of said bar and coiiperating to press said contact shoes against said strips, an operating handle for slidahly actuating said switch member, and a spring coiled around said bar and bearing against the wall of said cup and against one of said upwardly projectin terminals, said slot being of a length to a low said switch member to move upon either of the endmost of said strips.

2. In a device of the kind described, in combination, a casing,a rod extending transversely of and connected thereto, a switch member having two depressed contact shoes at opposite ends thereof, said switch memher being slidahly guided upon said rod, a pair of contact arms mounted in said casing, a sprin switch member'out of engagen'ient with said contact arms, and a tubular handle slidably projecting into the wall of said casing, being secured to said switch member so as to actuate the same and telescopically fitting said rod.

In testimony whereof I :iltix my signature.

HENRY A. LYON.
