ARMATURE FOR DYNAMO. ELECTRIC MACHINES.
Patented Dec. 12', 1882.
UNITED STATES PATENT @EETQE.
ANDBElV B. FISHER, OF UNION CITY, INDIANA.
SPECIFICATION forming part of Letters Patent No. 269,036, dated December 12, 1882,
Application filed July 26, 1582. (No model.)
To all whom it may concern:
Beit known that 1, ANDREW B. FIsHER, 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 useful Improvements in Armatures of Dynamo-Electric Machines, of which the following is a specification.
My invention relates to an improved artnature of a dynamo-electric machine.
The object of my invention is to increase the efticiency of the armature by arranging the metal so that the entire mass will be subject to a more rapid magnetic change as it is revolved between themagnet-poles, and to cheap en and simplify the cost of the construction, all of which will be fully explained in the description of the accompanyine drawings.
Figure 1 represents a longitudinal central section ot'my improved armature with the bob bins removed. Fig. 2 is an end elevation of the same. Fig. 3 is a detail elevation of one of the convolute ribbons and its series of polar pins.
A represents the shaft of the armature.
B B represent the spider-at ms at either end of the armature, being secured to the shaft by hubs I) b.
0 represents tie rods or strips of non-magnetic material, which are secured to arms 13 B in position parallel to the axis of the shaft, and form the base and supportingd'rame tor the inner periphery of the series of convolate ribbons.
D represents rings made of soft-iron ribhon, preferably insulated with any suitable substance bel'ore winding, and wound concentric to the axis and supported by the tie rods or strips 0, to which they are attached by means of iron or other suitable pins or bolts, E,\vhich are inserted through holes pierced in the tiestrips or cross-pieces (J, and through the convolute ribbons D,which are pierced with suitable holes i'or the purpose. These pins are allowed to extendaconsiderabledistancethrough and beyond the ribbons D to form polar projections of the. armature. The rings D are placed a sntlicient distance apart to allow airspaces H, which provide suitable ventilation to the armature and prevent heating of the metal.
I represents bent extensions of the outer pins, E,which form suitable hooks, ttpon which are wound the wire-bobbins. Various methods may be employed for winding the bobbins of the armature. It may be Wound either upon the Siemens or Grannne plan, as desired.
Either the hubs I) b or the tie-strips 0 should be insulated from magnetic connection with the shaft A, or the arms B should be made of 60 diamagnetic material.
I claim- 1. An armature for dynamo-electric niachines, composed of the trame A B O, the convolute iron rings or ribbons D, and the pins E, said rings or ribbons being separated to provide the air-spaces H, substantially as described.
2. An armature. for dynamo-electric machines, composed of the frame A B U, convolute iron rings or ribbons D, and pins E, extending beyond the rings or ribbons to form polar projections, said rings or ribbons being separated to provide the air-spaces 1l,substantially as described.
In testimony whereot'l have hereunto set my hand in the presence of two subscribing witnesses.
ANDREW B. FISHER. Witnesses:
JAMES M. STARBUCK,
