Original application filed September 80,-1915, Serial No. 58,264. Divided and this application filed July 10,

county of Montgomery, have invented certain new and useful Improvements, in Engine Startin Systems, of which the following is a ful clear, and exact description.

This invention relates to improvements in starting systems for internal combustion or explosion engines, and more particularly to that type of system which is adaptable for use with engines capable of operating either in a forward or reverse direction.

One of the objects of the present invention, is to rovidea starting system in combination with a reversible engine, which may be so coupled up to said engine .as to crank the engine in either a forward or reverse' direction, in accordance with the direction in which it IS desired'to have the en ine run, after it has once been started.

6m manner of attaining the above object may be by providing two prime movers, one of which bein capable of operation in one direction -whi e the other is capable of operation in the opposite direction,- and also providing a luralityof connectingunits or devices which may be actuated to couple prime m'overs to the ,engine, so as to operate the engine'in either a forward or reverse direction.

In combination'with the above mentioned prime movers and their" respective connect-,

ing units, there is provided a controlling plurality of -o erative ing element 1s moved to-one of its operative positions, one of said prime'movers will be connected to the engine by means of one of the connecting in one direction;

The functions of this controlling element, when moved to another of its operative po sitions, is substantially the same with respect to another prime mover. The result of the above arrangement and construction is that when one of the prime movers is brought into operation, the engine may be cranked in one direction, while when another of the prime movers is brought into units, to turn said: engine America,

operation, the engine will be cranked in an o posite direction.

The present-application is a division of my co-pending application, 30, 1915,Serial Not-53,264.

In the present form of the invention, the

starting device includes separatemotors,

' one of which is mounted on each side of the engine, so that this connecting device may be readily shiftedto couple up that particular motorto the .engine,-,to' crank the engine in one direction, while when it is defiled September sired to crank the engine in an opposite directiore. another cranking device will be shifted into position to couple another motor with. the engine, whereby the engine will be cranked in an opposite direction. f

-By referring to the drawing, the starting device or system includes two separate prime movers or electric motors, designated by the numerals 120 and 121,- one of which is mounted on each side of the engine.

In the present invention, of current is, employed as at 122, and has suitable circuit connections with the respectifve motors, as will be described hereina ter.

The main operating or controlling memher 123 is suitably mounted in such a manner that it of operative positions, in any one of whic positions the circuit connections between the source 122 and one of the motors will be closed concomitantly with the completion of the shifting of one of the connecting units.

- By referring to the drawing, the operation of the system will be described when the same is brought into operation by the shifting of the controlling member into the extreme right-hand positron.

Upon the initial movement of this controlling member, the connecting unit 124 will be moved toward the flywheel 125, and

concomitantly an initial movement will be imparted to the motor 120 by the closing of the following circuit, through the, effect of a bridgingelement 126, carried by the controlling member 123: from the battery 122, conductors 127 and 128, through the series field winding 129, across the brushesof the motor 120, through conductor 130 to the common terminal 131, across the may be moved to a pluralit*- a single source 128,. through theoppos te side of the battery, via conductor 134? i v The object of imparting a'n'initial movement to the motor, in the connecting up of the pinion of the connecting unit with the flywheel gearing.

Now, as soon as the pinion 124: has been brought into enmeslnnent with the flywheel gearing a determined degree, the controlling member closethe following circuit, which may be designated the main cranking motor circuit: from the battery .122, conductors-127 and series field winding 129, across the brushes of the motor 120 to lead wire '130, a. common termmal 131', through the bridging element -126--to1 the terminal 135 and thence back to the battery, via con- -duetor"134. -VVhenthe engine has become self-o erative, the controlling member 123 may: 'released, and the spring 136 will effect the unmeshinglmovement of gear 124, and will restore t emember 123 to inoperative position. I v

,If it is .desiredto crank the engine in a directionopposite to that resulting connecting the motor I 120 therewith, the main controlling lever 123 ,should be shifted to its extreme left-hand nperative position, in whichcase .the motor 121 will be conneeted up to the flywheel gearing, and a substantially duplicate set of circuit connections will be so eflt'ected as to give the required operations to the motor. Spring 137 will be effective, upon the release of memher. 123, to disconnect the motor 121 from the fly-wheel, and to restore member 123 torlnoper'ative osition. I x While the 'orm of mechanism .herein shown and described constitutes a preferred formof embodiment of theorinvention, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.
