METHOD DF WINDING FIELD-MAGNETS.
SPECIFICATION forming part of Letters Patent N0. 397,705, dated. February 12, 1889. Application iiled September l5, 1888. Serial No. 285,525. (No model.)
Be it known that I, THOMAS A. ED1s0N,of Llewellyn Park, in the county of Essex, in the State of New Jersey, have invented a certain new and useful Improvement in the Method of Winding Field-Magnets, (Case No. 7 98,) of which the following is a specification.
The object of my invention is to providea simple and convenient mode of winding the field-magnets of dynamo-electric machines with their wire-coils,whereby I am enabled to cast the magnet-cores with their pole-pieces and yokes in one piece instead of making perspective view ofv the cylinder and the dethem separately and afterward bolting them together.
It has heretofore been found necessary in most cases to wind the field-magnet core by 'itself and afterward bolt it to the other parts of the magnet, because the operation of winding aftertheparts were secured together would be exceedingly inconvenient, if not imprac ticable.
The main feature ot my invention consists in placing upon the c ore a cylinder adapted to be turned, and turning said cylinder to wind the wire upon it, the cylinder beingleft on the core under the coils.
.My invention is illustrated in the accompanying drawings. A
Figure 1 is a viewof a eld-magnet,show ing the operation of my invention; Fig. 2, a
vices for turning it; Fig. v3,9. View of one of the parts of which the cylinder is composed.
Im making the kind of machine illustrated 'and quickly wound thereon.
der made up of two halves, a a. This cylin-` der may be made of any suitable material;
-but I prefer to make it of thin wood or of card-board.`- At'onefl end the cylinder is-.provided with a grooved ange, b, and by means of a suitable cord or belt, c, operated by suitable power, as illustrated in the drawings by the shaft d, the cylinder is rotated on the magnet-core, and the wire e, being fed onto the cylinder in any suitable manner, is readily The belt being removed from the cylinder, the winding is complete. The two halves of the field-magnet will be bolted together at f. f NVhatI'claim is- 1. The methodof winding a magnet, which consists in placing a cylinder on the magnet core and turning said cylinder to wind the wi re thereon, substantially as set forth.
2. The method of winding a magnet-core, which consists in placing onthe core a cylinder made in two halves and turning said cylinder so as to wind the wire thereon, substantially as set forth.
This specificati on signed and witnessed this 31st day of August, 1888.
