The core or flux val ve is nfbunted on the shaft 21 which is driven by the engine shaft 22 through the gears 23-% which are of such size that the shaft 2l makes two revolutions for each revolution of the engine shaft. The gear2et is fixed to the sleeve 25 which is mounted for independent rotatioh on the shaft 21. The sleeve 25.is provided on its outer end with" a single tooth ratchet 26 which engages a similar ratchet on the sleeve 27, which is movable longitudinally of the shaft but is splined thereto, so that it rotates with the shaft. The sleeve 27 is held against the sleeve 25 by the spring 29 surrounding the shaft. As the. engine shaft revolves, the flux valve is also revolved, through the agency of the clutch, but when the engine shaft is stationary, the flux valve shaft may be rotated in the proper direction by the crank or handle 30, thereby allowing a current to be produced when the engine is at rest. This rotation does not disturb the relation between the position of the distributer and the position of the pistons in the timing of the spark is correct.

Arranged between the handle 30 and the valve shaft is a clutch which becomes disengaged when the engine starts, thereby allowing the handle to remain at rest. The

clutch consists of the toothed member 51 formed on the sleeve 52 loosely mounted on the valve shaft and to which sleeve the handle is attached. Arranged on the valve shaft is a similar toothed member 53. Bearing against the sleeve 52 is a spring 54 which operates to normally hold the toothed members apart. When it is desired to produce a spark with the engine at rest, the sleeve is pushed in, compressing the spring and bringmg the two parts 'of the clutch into mesh and the handle is rotated. The clutch on the opposite end of the shaft allows the shaft to be rotated by disengaging it from the engine shaft.

Loosely mounted on the sleeve 25 is the fiber drum 31 of the distributor. This drum is rotated at the proper-speed by the connected-gears 32'33 mounted on the stub shaft 34. Gear 32 meshes with a gear 35 formed on the end of the sleeve 25, and gear 33 meshes with a gear 36 on the drum. Embedded in the circumferential face of. the drum is a metal ring 37 having an offset tongue or section 38, which comes into contact alternately with the brushes 414l2 is ae, which are connected to the respective spark plugs of the four cylinderengine. Bearing against the continuous ring 37 is a brush 45 which is connected to the sparking circuit. i

In order that'the current mav he directed a single winding arranged in said channels 1 to the sparking circuit at the proper int vals and to the lighting circuit at of times, a contactor or switch operated by rotating shaft is necessary. At the valve shaft is a disk 46 hav pression 47 formed in the circurn face thereof. Mounted on the casing or Q2 48 attached to the frame of the mag-n a' spring held contactor arm as hearing a roller engaging the face of the disk. 7 is evident that as the disk revolves, the re moves into and out of the depression causing a movement of the free end of ne arm 49. Secured to the free end of the i is a sleeve 56 in which are arranged as opposite ends, the contact points ai J Mounted on the casing l8 and in l therefrom and from each other nals 61-62 of the sparking and light.-. circuits respectively These terminals are 5. -7 arranged adjacent the contact points so that when the roller is riding over face of the disk, the point 58 is in can with terminal 62 closin the lightin c1 and opening the spark circuit, and when roller enters the depression in the disk, t- I point 57 is in contact with terminal 612,

ing the sparking circuit and opening the lighting circuit. In order that no may occur at these contacts est-he circuits are opened and closed, I so arrange the con tact points so that the circuit to be made established before the existing circuit is broken. Th s is accomplished by making contact points 57-e58 slidahle within the sleeve 56 and holding them pressed'apart by the spring 6%. That point which is in cir ouit is pressed into the sleeve by the contact ing terminal, to such an extent, that as sleeve moves away from said terminal, point does not reach the end of slaand be separated from the terminal until other terminaland contact point are in con tact. Attached to the casing 48 at'a suitable place is a rocker arm 65 to which is attached a lever or arm for rotating the casing when it is desired to advance or retard the spark. One end of the coil is is connected to the contactor arm 49 and the other end is connected with the lighting circuit and-with the low tension side of the sparking circuit.
