CHARLES M. JORDAN, OF \VASHINGTON, DISTRICT OF COLUMBIA.

ELECTRIC-CURRENT REGULATOR.

SPECIFICATION forming part of Letters Patent No. 536,530, dated March 26, 1895. Application filed February 13,1895. gerial No. 538,249. (No model.)

To aZZ whom it may concern:

Be it known that I, CHARLES M. JORDAN, of Washington, in the District of Columbia, have invented certain new and useful Improvements in Electric-Current Regulators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to the method and apparatus for regulating either continuous or alternating electric current circuits.

The primary object of my invention is to provide motors, one driven by a circuit not subject to the fluctuations of the working circuit, and the other subject to the fluctuations of the working circuit, the two motors operating in opposition to each other for moving or controlling an electric current regnlator within the working circuit.

Another part of my invention relates to the construction of the moving part of the apparatus which is based upon a well known principle of kinematics and is applied by the action of two wheels or disks movable around axes approximately at: right angles to each other, on a sphere free to move in all directions by which the sphere will take on a combined motion around a third horizontal axis, forming a certain angle with each of the two others. The velocity of the rotation of the sphere will depend upon the absolute velocity of the two motions, but the direction of its axis will depend upon their relative velocity.

Another feature of my invention consists in the introduction in the circuit of two motors, the field and armature of onebeing acted upon by the constant strength of current, while in the other the armature is made to carry the current of constant strength, the field being excited by the current which varies with consumption.

In the drawings I have illustrated the regulator as connected up in the manner preferable when it is to be employed for controlling the consumption of energy on a continuous circuit, although the mechanical features and constructions hereinafter described, are applicable to alternating currents as well.

In the accompanying drawings, Figure 1, is

a perspective or isometrical projection of an automatic regulator. Fig. 2 is a sectional view of the satellite wheel, its arm and vertical shaft, with the gear wheels and arm acting on the segments of the resistance coils. Fig. 3 is a plan view of the apparatus. Fig. 4 is a plan view of the segment and lever connected therewith, also the segmental gearwheel attached to the bottom of the vertical shaft.

Referring now to the drawings, A is a metal sphere which is placed upon and supported by the small wheel B, the disks C and D and the small ball E said ball being held in a receptacle in the standard F, and is free to move in any direction, it serving solely for maintaining the sphere A in place, while the disks C and D communicate motion to it.

The disk C is attached to the shaft Gr of the armature H of the motor I, said motor being in a branch circuit 1) and b of high resistance across the mains a and a as indicated, so that it will be traversed by a current con stant in amount.

The disk D is attached to the shaft Jof the armature K of the motor L. The said armature K is in the same branch I) and l) of high resistance as the field and armature of the motor I, while the field exciting coils of the motor L are included in the main electric circuit with the translating devices, as shown in Fig. 3, so that the strength of the field will vary with the consumption of energy on the circuit.

M is an artificial resistance in the circuit of the motor I, and the armature K of the motor L.

The disk C, actuated by the motor Lgives a rotation of uniformity to the sphere A, while the rotation of disk D, actuated by motor L, is dependent upon the consumption of enorgy in the circuit a and a, and deflects the instantaneous axis of rotation of the sphere A at a point between said disk, to a degree so much the greater or lesser in proportion as the revolutions of the armatn re K is increased or diminished by the amount of current passing through the circuit.

A sphere A rests upon the small wheel B, which carries the bulk of its weight and is free to revolve with it so that the wheel 13 will seek to economize work, and will so place itself as to roll over the sphere without sliding, and its axis will then be parallel with the instantaneous axis of rotation of the sphere A.

The wheel B is mounted on an arm N (Fig. 2) movable around a vertical axis 0, placed beneath the center of the sphere A, said arm N resting on the ball bearings P, to reduce friction.

At the bottom of the shaft or axis 0 is attached a segment or gear-wheel Q (Figs. 2 and 4) which meshes with a smaller gear-wheel R on the shaft S, and to the same shaft is attached an arm T, at the terminal end of which is an arch shaped piece which makes contact with the ringU and segments V of the resistance coils interposed in the main circuit.

The working parts of the apparatus rest on a sub-base WV while the ring U and segments V rest on the base X.

I will now briefly describe the working of the regulator. The disk 0 revolving, but no current passing through the main line to translating devices and consequently the disk D being quiet, the sphere A will revolve in the same plane as the disk 0. The small wheel or satellite B will also be in the same plane and the arm T will be on the segment of the resistance coils V representing the highest resistance. Vhen the current on the main line is turned into a translating device or devices the current passing through the field coils of the motor L will set the disk in motion and the plane of revolution of the sphere A will be changed to a point between and representing the mean of the velocities of the disks 0 and D. At the same time the small wheel B will move to the same plane and turn the arm T to a segment representing less resistance and so on as more current is turned on. In turning off current the reverse of this will take place, the disk D will gradually revolve slower, the sphere A gradually approach the plane of revolution of the disk 0 the wheel 13 also, and the arm turn to segments representing greater resistance.

It is obvious that the resistance V could consistently be placed in the field magnet circuit of the dynamo if circumstances so dictated.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
