Claims

Claim lst. In a commutating apparatus for dynamo-electric generators a disk or arms revolving with the armature coils and carrying flexible strips of copper, or other metal, each connected to a free terminal of the armature coil, and adapted by centrifugal action or otherwise to bear upon the segments of a divided and adjustable circular collector, in the manner specified and set forth. 2nd. In a commutating apparatus for dynamo-electric machines, the combination of a disk or radial arms revolving with the armature, and counterbalanced brushes revolving with said diik or arms and adapted by the action of centrifugal forge upon the counterbalances to press inwards towards a point concentric with their arc of revolution. 3rd. In a commutating apparatus for dynamo-electric machines, a contact brush or brushes attached to each free terminal of the coils of a revolving armature, and adapted by centrifugal action or otherwise to bear upon a collector or collectors placed concentrically with the axis or revolution of the armature. 4th. A collector to which positive and negative connections may be made and consisting of two rings, of two active and two neutral segments each, the corresponding active segments of each ring being in electrical connection and adapted to ,move upon each other to increase or diminish the length of brush contact on each segment with the object of varying the electro-motive force of the machine. 5th. The combination of a current collector, consisting of two rings, of two active segments each, the corresponding or positive and negative segments of each ring being in electrical contact or connection, with an eleotro-magnet, the actuating wire of which is in the main circuit, or a shunt derived from the main circuit of the generator, and with mechanism adapted to move one ring of the collector in relation to the other backwards or forwards, to lengthen or shorten the effective contact of each brush terminal of the armature coils, and so vary, the electro-motive force of the current produced. 6th. The combination, with a disk carrying the brush terminals of the armature coils of a dynamo-electric machine, of a series of blades adapted by their centrifugal action to produce a current of air through the segments of an adjustable collector for the purpose or preventing injurious heating of the collector segments. 7th. In a commutating current collector, the combination of the insulating disk V the flange Y, and the rings S S1, in the manner specified. 8th In a current collection and regulating apparatus for dynamo-electric machines, the combination of the disk , carrying the fan blades F, and balanced brushes B, each connects to a coil terminal of the armature, the segment current collectors S Si. mounted upon the carrying flange Y, and the insulating disk V, the regulating magnet M, and core C, with dash pot Di and lever L attached to adjustable collector segments S S. 9th. A regulating device, consisting of an electro-magnet or helix in the main, or a shunt derived from the main circuit of a dynamo-eleetric generator adapted to vary the working length of each segment in a collector composed of adjustable positive and negative segments. 10th The combination, with stationary or adjustable circular collectors for dynamo-electric machines, of the automatic oiler I and groove or trough R, with capillary tubes , which allow the oil to flow down through the collector upon the revolving brush terminals of the generator having tiers of ledges and the motor and carriage for the wires, said motor and carriage being connected by a hinged or pivoted rod, substantially as and for the purpose set forth.
