series of cylinders by having the current therefrom electro-magnctically distributed to said cylinders.

This invention consi in a source of high tension current, preferably an induction coil, the prin'iary winding of which may be connected to a plurality of sources of low tension current, of a series of spark-plugs, a separate circuit between each spark-plug and the secondary winding of the induction coil, an electro-n'iagnetic switch in each said circuit, a current distributer operated by an engine, a circuit connecting the winding of each electroinagne-tic switch to the primary winding of said induction coil and to said distributer, which circuits are closed in sc' quence by said distributor as a current is desired at the spark-plugs to explode the 'by the arm 3 secured to the shaft 4 which is driven by the engine. The arm 3 and shaft 4 may be grounded by the wire 5. Wires 6, 7, 8 and 9 connect to the various contacts 2 and to the windings of the mag nets 16, 17, 18 and 19, respectively. -The opposite ends of the windings of these magnets connect to the bus-bar 15 by wires 14.

a. current passes to its winding, draws up an armature 26, 27, 28 or :29, which is connected. to the bus-bar 21 by means of a wire 36, 37, 38 or 39, and when the armature is drawn up against the core, a high tension current will pass from the bus-bar 21 to one of the spark plugs 46, -17, 48 01' d9 (of which there is one for each cylinder of the engine), over the wire 56, 57, 58 or 59, ac-

cording as the arm 3 engages with the contact 2 at the end of the wire 6, 7, 8 or 9. The spark-plugs may all be of any well known construction and their cylinders are grounded, this fact being indicated by the wires 2 although the engine itself constitutes the ground The primary winding 30 of the induction coil connects to the vibrator 31 and to the switch arm 32. A storage battery 33 connects to the contact 34 and is grounded by the wire 35. A magneto 10 connects to the contact ll of this switch and is grounded by the wire 12. The

magneto will preferably be driven by the engine and produce an alternating current. The contact point 43 of the vibrator connects to the bus-bar 15 by means of the wire 44. I

The secondary winding 50 of the induction coil connects to the bus-bar 21 by means of a wire 51 and to the wire 44 by means of a. wire While four spark-plugs are shown, it will be understood that this number may be varied as desired.

As the arm 3 engages the contact 2, at the end of the wire 6, a current will flow from the magneto 4:0 over the primary winding of the induction coil to the bus-bar 15, over the Wire 14, the winding of the magnetil6, causing its core to draw up the armature 26, then over the wire 6, the arm 3 and wire 5 to ground. The secondary current will be from the wire 44, over Wire, 52, the secondary winding 50 and Wire 51 to the bus-bar 21, thence over the wire 36, switch 26 and wire 56 to the spark-plug 4L6.

Each spark-plug thus receives a current during such time as the arm 3 engages the contact 2 at the end of the main Wire of the primary lead 6, 7, 8 or 9 of that particular spark-plug, and this current stops as soon as this engagement is broken, even if the magnet should be slow in releasing its armature, which slowness may be desirable on account of the interruption in the primary circuit by the action of the vibrator 31. As only one induction coil is employed,

absolute synchronism is assured, which is impossible where aseparate induction cell is used for each spark-plu By mounting the pivot (3() of the armature 65 on a metal frame 61 quite ,near the core rotatable to advance or retard the ignition sparks in the usual manner, this being indicated by the arm 66 and the arrows leading therefrom. Details of construction are omitted for the reason that'all the elements employed are wellknown, the novelty residing entirely in the combination or assembling of these elements.
