To all it may concern:

Be it known that I,IRICHARD VARLEY, a citizen of the United States, residing at Englewood, in the used as the sole source of primary current, and batteries of every sort are dispensed with.

The use of batteries in motor vehicles is attended by I much trouble and annoyance mainly on account of the the light run-about class, and with an engine having fact that the amount of energy required for the engine ignition is large and beyond the capacity of any convenient portable battery, unlessthe same is renewed or recharged very frequently. Accordingly engine driven" magneto generators are frequently used to supply the ignition current when the engine is'running. Such f generators answer requirements except thatthey do not generate a current when the engine is at rest to en- In the drawings: Figure 1 is a view of an auxiliary 1 magneto generator included in'an ignition system and embodying the principles of my invention; Fig. 2 is a detail view-of a part of the same. Fig. 3.11s detail view showing a slightly modified arrangement. Engines with four or more cylinders are now almost universally used onall motor vehicles, except those of this number of cylinders it always theoretically possible to start the engine from a'state of rest, since one of the four cylinders is bound to be'withi'u a quarter of a.

revolution of the nornral ignition point, and the ignition timing devices are always capable of being manipulated enough to reach the ignition point for such one of the cylinders within these limits. Since this cylinder contains a carbureted mixture remaining from the intake when the engine was last running, it follows that such charge will be exploded I and the engine started. This is not only theoreticallygthe case, but ispractically true for all cars which have finelybuilt cngines. The only requisite, therefore, is to obtain an ignition spark of suflicient intensity to ignite the charge which is often cold and only slightly compressed when the engine has been standing idle for a long time. The.

engine driven dynamo is of course not avail able when the engine is at rest.

In carrying out my invention I aim to provide a source of current which is compact and convenient, and

which has abundant energy to 'fire a poor mixture which has been'left standing in the cylinders for a long time. i I further aim to automatically cut out this auxiliaify sour'ce from action when the engine hasbeen started into operation.

Referring to the di'awings in which like part sare desig- I nated by the same reference sign, 1 designates broadly a magneto generator which is formed to be attached upon the dashboard of a motor vehicle, and in a position convenient to be engaged by the foot of the chauffeur or his niechanician; This magneto generator is conveniently made with a box-shaped frame or casing 2,

open at its front side, and having screw holes 3, by

which any ordinary cover plate (not shown) may be secured thereto. 4 indicate the permanent magnets received upon -polepieces 5, attached to the- casing 2, and 6 denotes the revoluble part or armature which is journaled in suitable bearings 7, on the pole pieces. This magneto may be of the ordinary or any desired form, and the details of its construction-constitute no part of my inven tion.

8 denotes a short shaft' journaled in the casing 2, and having a large gear wheel 9 thereon. which is geared to rotate the armature 6 by a multiplying gear train l0, l1, 12, the pinion 12 being on the armature shaft. Gears 10 and 11 are fixed on a shaft 13 jonrnaled'in the casing. I provide meansjor rotating the shaft 8 through part of a revolution by the movement of the foot. For this purpose a ratchet wheel 14 is fixed to the shaft 8, and a spring pressed pawl 15, carried by a lever 16, loose on shaft 8 is effective to turn the ratchet wheel 14 when the lever 16is'rocked. The lower end ofthe leverl6, is

provided with a pedal 16.

17 d tiotes a spring attached to the lever 16 and the casing 2, by which Said lever is normally retracted. In its retracted position the lever rests against-a fixed stop'l8, which also constitutes an electrical contact, said stop being insulated from the casing 2 by an insulating block 19. I

' One of the armature terminals of the magneto generator 1 is grounded on the casing 2, while the other tcrminal has the ordinary spindle end connection with a plate 21. This plate 21 is in electrical connection by a wire 22,.with the stop or contact 18. This brush may also be connected in the ignition circuit in the manner shown diagrammatically at th 0 lower part of Fig. 1.

The operation is as follows: The induction coils A, A A and A", are connected through any suitable'circuit controlling devices B, C, with a dynamo or other suitable current source D, grounded at E. The nagneto generator comprised by my invention is included in this circuit, the connection n being grounded on the casing 2, while the connection n runs to the plate 21.
