MAGNETO-ELECTRIC GENERATOR.

ing is a specification.

This invention relates to improvements in magneto-electric generators for gas-engine ignition or other purposes in which a rotative mechanical movement generates an electric current, which may be used either directly or through an induction-coil for gas-engine ignition or for other purposes for which such current is suitable. 7

The object of the invention is to provide a generatorin which the winding is stationary and permanently connected in the circuit, thereby avoiding the necessity of conducting the current through either hearings or brushes, which are more or less liable to fail to properly conduct said current, due partly to the necessity for lubricants, and to provide an inductor which will be rotated within the stationary winding, so as to avoid the jar and strain incident to the changes of an oscillatory inductor in a rapidly-running machine.

The object where the generator is used for gas-engine ignition is to change the time of movement of the inductor with relation to the movement of the engine-shaft for changing the time ofignition.

The object, further, is to give the generator a quick motion regardless of the engine speed.

The object also is to simplify the construction of the generator so it can be safely operated by uneducated or inexperienced persons, which will be durable and of low cost to manufacture;

We accomplish the objects of the invention by the mechanism illustrated in the accompanying'drawings, in which Figure 1 is a longitudinal vertical central section of our improved generator, a detailin section of the end of a gas-engine cylinder with a sparking plug in section, the sparking plugbeing connected electrically with the gen- Serial No. 147,701.

erator and having an induction or Ruhmkorif coil in the circuit; Fig. 2, an end elevation of the generator looking in the direction of the arrow 2 shown in Fig. 1, and Fig. 3 a vertical section on the line 3 3 of Fig. 1.

Like letters of reference indicate like parts throughout the several views of the drawings.

The reference-letters A A A indicate powerful permanent magnets; B B, the moving part or inductor, which is 'rotated to reverse the magnetic lines of force; C C, the arma ture or winding of insulated wire, and D D D D the pole-pieces of magnets A. If the inductor B B be rotated, the magnetic flux furnished by the magnets A will be reversed in winding 0 C twice during each revolution, and an electric current will be generated in winding C C at each reversal of said magnetic flux.

Fig. 1 shows the invention in connection with an induction or Ruhmkorff coil H and ignition-plug I, both of usual and well-known construction. The ordinary electromagnetic vibrator may be used on the coil H; but we prefer to use an interrupter in the primary circuit of coil H, located on the generator-body for more convenient regulation, such as we will now describe. The inductor B is mounted in a fixed manner on the shaft S, and mounted outside of the machine in a fixed manner on said shaft S is a wheel having the cam G. When the shaft S is rotated, this cam contacts with a lug R on the free end of a spring-bar F. E is a terminal for one of the conductingwires. E and F when actuated by the cam Gr constitutev the interrupter in the primary circuit of the coil H. The time of ignition at the plug 1 is when the circuit is broken at the interrupter by the contact of cam G with the lug R. In gas-engines it is often desirable to vary this time with relation to the travel of the piston and the rotation of the engineshaft. As the shaft S is driven by some suitable connection, whether direct or indirect, with the engine-shaft, the time of ignition -may be varied by disconnecting the shaft S and turning the inductor to the desired position before connecting the shafts up again, or it may be done more conveniently while the engine is running, if desired, by the mechanism shown in Figs. 1 and 2, in which M is a hand-lever, having a sleeve at its lower end mounted loosely on shaft S. Adjustment of its upper end is held by rack P and pawl Q. Mounted loosely on shaft S outside of lever M is cog-wheel J, which is connected with the engine-shaft in any suitable manner. (Not shown) Mounted in a fixed manner on shaft S outside of wheel J is the crank K, having a pin at its outer end connected by spiral spring N with the pin 0 on lever M. The wheel J has the stud-pin L, which contacts with the crank K by the rotation of wheel J and compels said crank, its shaft S, and the inductor B, mounted on the shaft, to move with it; but as soon as the pin on the end of the crank passes the dead-center at the bottom of the wheel J (which dead-center will fall on the continuation of the line drawn through the centers of pin 0 and shaft S) the spring N will bring the crank quickly back past the position shown in the drawings, causing the cam to break the circuit at the interrupter. This time of release of the crank at dead-center may be delayed or hastened by shifting the lever M in the proper direction along the rack P. It is evident that if the gas-engine by which the magneto isoperated runs fast enough the spring will not be required and that our invention would be operative if conneeted to rapidly-moving gas-engines by gears on y.

The ordinary electromagnetic vibrator may be used on the coil H without the cam-interrupter, the ignition occurring when the current has attained sufiicient strength to operate the vibrator.

It is evident that the machine would operate with so-called primary method of ignition,wherein the electrodes within the engine are separated at the proper instant.

We are aware that prior to our invention magneto-electric generators have been used rotative and oscillative in which the electric current is generated by motion of the arma ture or winding, that same have also been used oscillatively in which the winding is stationary and within a movable inductor, said inductor moving between said armature or winding and the pole-pieces. In our invention the inductor is movable within a stationary armature.

In the following claims the word synchronously is used to express the condition in which the magneto and the engine are connected so that the generator will furnish one pulsation of an electric current at the time that the engine requires an ignition-spark, rather than an equal number of revolutions with the same or no cyclic variations.
