GENERATOR FOR ELECTRICAL IGNiTERS.

SPECIFICATION forming part of Letters Patent No. 608,895, dated August 9, 1898.

Application filed March 30, 1898.

To all whom it may concern:

Be it known that I, BENJAMIN MCINNERNEY, a citizen of the United States, residing at Omaha, in the county of Douglas and State of Nebraska, have invented certain new and useful Improvements in Generators for Electrical Igniters, of which the following is a specification.

In a separate application forLetters Patent, Serial No. 675,776, filed March 30, 1898, I have set forth means for varying the ignition-point of a gas-engine, consisting of a generator in two parts, one carried by a moving part of the engine and the other arranged in proximity to the path of the moving part, but adjustable, so that the two parts may be caused to coact to produce a current at different periods of the revolution of the main shaft. In the device specifically claimed in said application one part of the generator consists of a permanent magnet and the other part a wirewound coil. This, while effective and embodying the broad principle of my invention, is sometimes attended with objections which it is the object of my present improvement to avoid, and this I do by the construction hereinafter described, and shown in the accompanying drawing, which illustrates a gas-engine with my invention.

The engine, of any suitable construction, has the usual foundation and frame, cylinder, piston, crankshaft connections, and fly-wheel 1). The fly-wheel supports one part of the generator G and the other part is supported by a carrier or support E. This support may be connected with the frame or base or otherwise permanently but adjustably supported, but preferably is an arm 13, connected with a yoke 19, turning freely on a sleeve projecting from the bearing of the crankshaft 4 and limited in its movement by two set-screws 2O .21, extending through the arms of a bracket 23, connected to the frame, between which set-screws extends from the yoke an arm 24. The parts are so arranged that in either position the support E will be on one side or the other of a vertical line extendin g through the axis of the shaft 1, so that the support will remain in th the position to which it is set.

When the flywheel carries the magnets Serial No. 675,775. (No model.)

and the support the wire-wound core, the weight of the part carried by the wheel, especially if the engine is small, may tend in some cases to unbalance the wheel, and the capacity of the generator is therefore limited by the necessity of restricting the weight and size of the movable part of the generator. To avoid this, I connect both the permanent magnet 6 and the wire-wound core 7 to the support E, so that they shall be isolated by non-inagnetie material, and I-place upon the fly-wheel keepers a a, constituting part of the generator, and which when opposite the poles of the magnet 6 and core 7 produce the requisite magnetic action and cause the current to be generated in the coils, passing thence to the igniter of any suitable character.

As shown, the core consists of a series of U-shaped plates with the wire coiled upon the forks thereof, and the magnet and core are secured upon opposite sides of the arm 13. As thus arranged the sizes and weights of these parts may be increased to any desired extent to secure currents of any necessary potential without in any way affecting the operation of the engine or demanding the movement of any material weight, inasmuch as the weight of the keepers is but slight what ever may be the size of the other parts.

\Vhen the engine is started, the support E is swung to the position shown in dotted lines, so that the charges are not ignited until the piston has moved away from the cylinderhead; but after the engine has begun moving the support is swung over to the position shown in full lines, when the charges will be ignited at an earlier period of the pistons movement. Any suitable electrical conductor serves to connect the generator-coils and the igniter, and in some cases there is a circuitbreaker 0 arranged at any suitable point and operated from any moving part of the engine and breaking the circuit when the current is of maximum efficiency.

lVhile I have shown one part of the generator as carried by the flywheel, it may be carried by any other rotary or vibrating or reciprocating part of the engine.

\Vithout limiting myself to the precise construction shown, I claim as my invention- 1. An electrical generator for electrical igcarried by one of the arms, stop devices Inn-- iting themovement of the other arm, and keepers carried by the fly-wheel,substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

BENJAMIN MOINNERNEY.
