Specification of Letters Patent.
Patented Jan. 19, 1909.
Application filed January 3, 1906. Serial No. 294,431.
T 0 all whom it may concern:
Be it known that I, CHESTER B. MILLS, a citizen of the United States, and a resident of lVilmerding, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Commutator-Bruhes, of which the following is a specification.
My invention relates to commutator brushes for dynamo-electric machines, and it has for its object to provide novel and improved means for securing flexible conductors thereto.
My invention is especially applicable. to
motors and other dynamo-electric machines of the commutator type in which thinner carbon brushes than those which are usually employed in direct current machines of corresponding capacities are essential to the most successful operation.
liigure 1 of the accompanying drawing is a View, in perspective, of a commutator brush embodying my invention, and Fig. 2
is a view, in development, of the part whereby a flexible conductor may be connected to the brush. 7
A commutator.brush 1, that is composed of carbon or other suitable-material, is provided, in its outer edge, with a longitudinal slot 2 in which is located a strip of sheet metal 3, from which there projects, at one end, a shorter and wider portion 4: that is partially separated therefrom by means of a slot or saw-cut 5 so as to enable folding One end of a flattened, flexible conductor 7 is clamped in the folded projection and good electrical connectidn may be formed between it and the projection and also between the strip and the brush bymeans of solder. The strip 3 serves also as a wearing piece with which the'free end of a spring-pressed lever of a suitable brush-holder (not shown) may engage. Since no portion of the device whereby the flexible conductor is connected to the commutator brush projects beyond the lateral faces thereof, free movement of the brush in the holder is permitted.
I claim as my invention:
1. The combination with a carbon oommutator brush having a slotted outer edge, of a conducting strip located completely within the slot except at one end which is provided with a folded'portion that projects at right angles to the commutator-engaging face of the brush, and a conductor clamped in the folded projection.
2 The combination with a carbon commutator brush having a slotted outer edge, of a strip of sheet metal so located in the slot that its exposed edges are fiush with the edges of the brush except at one end which is provided with a portion that projects at right angles to the commutator-engaging face oi the brush, and a conductor secured to said projecting portion. I
In testimony whereof, I have hereunto subscribed my name this 27th day of December, 1905.
CHESTER B. MILLS.
