PATENT OFFICE.
FOREE BAIN, OF UNION CITY, INDIANA, ASSIGNOR TO THE FISHER ELEC- TRIO COMPANY, OF SAME PLACE.
ARMATURE FOR DYNAMO-ELECTRIC MACHINES.
SPECIFICATION forming part of Letters Patent No. 268,980, dated December 12, 1882.
Application filed July 26, 1882. (No model.)
T all whom it may concern:
Be it known that I, FoRIiE BAIN, a citizen of the United States, and a resident of Union City, in the county of Randolph and State of Indiana, have invented certain new and use ful Improvements in Armatures for Dynamo- Electric Machines, of which the following is a specification.
My invention consists in forming an armaro ture of concentric iron rings or ribbons placed in series side by side, held in position concentric with the shaft by magneticdisks, between which each series is wound, said series of concentric ribbons and their supporting-disks being supported upon adiamagnetic frame, and
separated from each other by intervening airspaces and insulating-washers.
The object of my invention is to provide an armature which will not heat, and to so place the iron forming the core ofthe armature that the entire mass will be subject to more rapid magnetic changes than arniatures heretofore constructed.
Figure 1 represents a longitudinal elevation 2 of my improved armature; Fig. 2, a cross-section of a partthereof; Fig.3, an end elevation, showing the method of winding the armature.
Arepresents the shaft with which the armature revolves and on which it is mounted; B,
0 a hub carrying spider-arms B, placed at each end of thearmaturetosupport thecore. These parts are made of brass or other diamagnetic material.
0 represents anuularrings, provided with a series of radial polar projections, c, and spaces d, in which the armature-bobbins are wound.
D represents a series of concentric arms or rods, made of diamagnetic material, which pass through holes or notches near the inner pe- 0 riphery of annular ring 0. The ends of these rods are either riveted or secured with nuts to secure the parallel series of annular rings O.
F represents thin iron rings or ribbons wound around upon the rods D and between 4 5 the washers E, so as to form the major portion of the armature-core, and such rings or ribbons are preferably coated with diamagnetic mate rial. The two outer of the series of rings are rigidly secured to the spider-arms B, and between each of the rings or ribbons Fare placed the annular binding-rings O.
E represents insulating-washers separating each of the rings or ribbons F from contact with its adjacent disk or binding-rings C, so as to form air-spaces and to prevent magnetic connection of the parts U and 'F.
G represents one of the bobbins formed of wire wound longitudinally around the rings C, as shown in Fig. 3. The wires G are insulated from metallic contact with rings 0.
I have found by experiment that the abovedescribed armature is superior to any I have heretofore used, and is practically a non-heating machine.
I claim- 1. An armature for dynamo electric machines, the core of which is formed of iron rings or ribbons wound upon the diamagnetic frame and magnetically insulated one from another, substantially as herein set forth.
2. An armature for dynamo-electric inachines, the core of which is composed substantially ot'a series of iron rings or ribbons wound upon a diamagnetic frame, and arranged between a series of annular rings, 0, which are insulated from the rings or ribbons, as herein set forth.
3. An armature for dynamo-electric machines, the core of which is composed substantially ofa series of iron rings or ribbons wound upon a diamagnetic frame, and-arranged between aseries of annular rings, 0, which are insulated from the rings or ribbons by intervening washers, which form air-spaces, as herein set forth. 5
In testimony whereof I ha ve hereunto set my hand in the presence of two subscribing witnesses.
