MARIUS JEAN BAPTISTE BARBAROU, OF NEUILLY-SUR-SEINE, FRANCE.

ELECTROMAGNETIC IGNITION SWITCH FOR INTERNAL-COMBUSTION ENGINES.

Application filed August 20, 1920. Serial No. 404,856.

To all whomit may concern:

Be it known that'l. llIARIUS JEAN BAP TISTE BARBAROU. a citizen of the Republic of France, residing at Neuilly-sur-Seine,

b in the Republic of France, have invented new and useful Improvements in Electro magnetic Ignition Switches for Internal- Combustion Engines of which the following is a specification.

It is the customary practice to carry out the ignition of explosion motors by the use of a magneto.

But in the case of motor starting devices it is not an easy matter to obtain the proper starting. by reason of the slow initial speed given to the explosion motor by the starter.

It is in fact recognized that a minimum speed of 60 to 70 revolutions per minute is required for the motor in order to obtain a suitable spark from the magneto. said minimum speed being the absolute speed at the moment of the occurrence of the compression. i. e.. of the ignition.

However in the case of a motor of mean or high power, it becomes impossible to provide a starter having a sufficient capacity together with a storage battery suitable for supplying the same, whereby the said minimum speed of 60 to 70 revolutions shall be obtained under all circumstances at the moment of occurence of the compression.

On the other hand the fact that a storage battery is provided for the lighting and for motor starting will afi'ord a convenient means for employing an ignition distributor supplied by a high tension coil.

This invention has for its object to utilize the high tension spark coil. which produces a constant spark at all speeds of the motor, to provide for the ignition upon starting the motor, while the magneto will secure the ignition at normal speed. These two operations are carried out in an automatic manner by the use of an apparatus termed permutator. which is the object of this invention.

In the accompanying drawings which are given by way of example:

Fig. 1 is a longitudinal axial section of an ignition permutator constructed according to this invention.

Fig. 2 is a corresponding plan view.

Fig. 3 is an end view of the left hand side of the same.

side.-

Fig. 5 is a diagrammatic view indicating the various electric connections between the permutator and the cooperating members of the ignition device.

As represented in the drawing, the ignition permutator according to this invention comprises essentially a metal casing having disposed therein the magnetic field member 6 of an electro-magnet, the disk-like armature 0 whereof is movable axially. The said armature is secured to a central core having the internal portion thereof constituted of an insulating substance e. The other end of the core is provided with a rounded stud f.

The movable assemblage of the electromagnet is returned to the inoperative position by means of the spring g.

The magnet coil h is constituted by a winding having one end thereof connected to the metal framework the other end being connected to the terminal iby the lug j. The terminal 2' is mounted upon the cover A: constructed. of insulating material.

At the other end of the casing a is in serted a block Z of insulating substance hav-' ing disposed thereon the three terminals m,

A cut out portion in the block 1 contains swinging therein the rocking member 77 also of nsulating material.

A metal cross pin 1 serves as a pivot for the same.

The rocking member 71 is provided upon its opposite sides with the two flat contact strips 1", r.

The strip 1' is in constant contact with the terminal m through the medium of the coil'd spring 8. while the strip 1- is maintained in constant connection with the terminal n by means of the spring blade 25.

The contact member a is on the other hand connected to the terminal 0.

The terminal 0 is connected to the ignition distributor D (Fig. 5) supplying the spark plugs, the terminal at is connected to the high tension spark coil C supplied by the battery Z, and the terminal m is connected to the magneto B. Connection is also made between the terminal 71 of the electro-magnet coil and a suitable terminal Q) on the high tension coil C whereby the current of the battery Z is supplied at the same time to the electro magnet of the permutator A and the spark coil C.

The connections are properly made by means of a combination switch W whose handle a is operated by the driver of the vehicle.

Y is the line connected to the generator.

The said handle is adapted to take three positions, viz

1-Full stop.

2-Operating with magneto.

3Operating with high tension spark coil for the starting.

Under the above conditions, the operation of the permutator is as follows:

In the normal position for the motor running with magneto, the switch being in the position numbered 1,, the contact strip 7" or" the rocking member is in constant contact with the contact. member 14, whereby constant connection is provided between the terminal 0 and the t'xrminal m, i. e., between the magneto B and the distributor D.

At the moment of starting, with the handle placed in the position start (numeral 3 of the diagram), the current is sent into the electromagnet h of the 'permutator whereupon the movable armature will be attracted and the stud f will exert a pressure upon the rocking member 9, causing this lat ter to swing. At the end of the stroke, the strip r will come in turn in contact with the member a. At this moment, by reason of the spring contact member 25, electric connection will be made between the ti'rminal n and the terminal 0., i. e., between the high tension coil C and the distruloutor D. The starter is put in action and the explosion motor will now rotate.

As soon as this latter commences running by its own means, the switch handle is placed in the position magneto (numeral 2 of the diagram).

The connection is now broken between the electro-magnet'of the permutator A and the battery Z on the one hand, and the spark coil C and the battery Z on the other hand.

The springs sand 9 will add their effect to drive back the movable armature, and the rocking member now assu'mesits normal position, whereby the magneto B is connected to the ignition distributor D. The ignition is thus definitely effected by the magneto B alone.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is An ignition electromagnetic switch comprising a casing, an energizing coil therein, a spring controlled core slidable axially through said coil and provided at one end with an insulating member, a rocker adapted to be operated by said insulating member, said rockerha-ving a rounded end, parallel. contact blades separate from each other on said rocker, one of said blades extending over said rounded end, a fixed contact member with which said contact blades are adapted to alternately contact, a returning coiled spring adapted to convey an electric current to one contact blade, and a spring blade in constant contact with th rounded part of the other contact blade and adapted to convey an electric current to the same In testimony whereof I have signed my name to this specification.
