DYNAMO OR MOTOR.

SPECIFICATION forming part of Reissued Letters Patent No. 11,354, dated July 25, 1893. Original 70,057, dated March 1,1892. Application to; reissue filed January 25, 1893. Serial No. 459,742.

of Brooklymin the county of Kings and Stateof New York, have invented certain new and useful Improvements in Dynamos or Motors,

of which the following is a specification.

The object of my invention is to construct a cheap, simple, and efiicient dynamo or motor; and it relates particularly to the form and arrangement of the framework constituting the field,- whereby the best results are It is of the spherical type, the armature and the iron-clad casing constituting the magnetic bond between the field magnets, being globular in form whereby I am enabled to make not only a most efficient motor, but it also presents exteriorly a fine appearance.

In the drawings Figure l is a central vertical longitudinal section of the motor; Fig. 2, a central vertical cross-section, and Fig. 3, an exterior View of one end of the same.

In constructing the invention I form the casing or shell in two parts divided centrally on a horizontal plane, the lower half or hemisphere A having a base 13 integral therewith and at each end a bracket or arm, asO D, in which the armature shaft is journaled. 'lhe u pper hemisphere E is a plain shell, and these two parts are united by m cans of serew-th readed edges, as shown,or in any other manneras for instance, by having them flanged and bolted together. Centrally within these shells are screw-threaded sockets to receive the serewthreaded ends of the field magnet cores F. These field magnets have their polepieces or heads G cup-shaped, the curved sockets in the ends being out out to conform to the shape of the spherical armature. The base II of the core is designed to fit snugly against the inner side of the shell. The armature shaft I, which passes horizontally through these shells, has centrally within a spherical armature-core I, and wound thereon in any suitable manner is the insulated wire, any form of winding being adapted for the purpose.

In Fig. 1. I show the shaft and armaturecore covered with insulated wire, as shown at J, and connected up with the commutator plates K, and one of the fieldanagncts is also wound, as at L; but I have made no attempt to connect up the wires, because the manner of connecting same forms no part of my invention.

My invention has particular reference to the construction and form of the iron-clad shell or frame forming the magnetic bond between the field-magnets, and incidentally to the attachments thereto.

Both the fields and the armature may be wound as desired but I prefer the ring type, with the outer surface spherical in shape and the inner surface flat. The coils are either wound on the ring by hand or are slipped'on after being wound,and the whole armature is fastened to the shaft by means of a non-magnetic spider, or in any way that will prevent its resting on the shaft; or it may be composed of a hollow spherical core, over the outer surface of which is wound the wire after being. insulated from the core. The field core is preferably covered with copper before being wound, and the wires may be wound directly on the core or on a spool and afterward slipped on.

By employing a spherical frame connecting the field-magnets, as shown, a perfect magnetic circuit is made, eliminating magnetic leakage, and by spherical poles and armatures the lines of force are concentrated more directly upon the armature, as well as giving the armature greater surface. I also claim that I am enabled to obtain by this a more intense field, slower speed, greater solidity and efficiency, protectioirto the-field and armature, ease of construction, and general simplicity in construction.

lVhat I claim as new is 1. In a dynamo or motor a hollow sphere made of magnetic material and included within the magnetic circuit of said dynamo or motor and inclosing the armature thereof substantially as set forth.

2. A dynamo or motor having its pole pieces and armature inclosed in a two part magnetic sphere, substantially as set forth.

3. A dynamo or motor having a'frame consisting of a hollow sphere of magnetic material, and field pole pieces upon the inner surface of the sphere magnetically connected ICO through the body thereof, substantially as described.

4. A dynamo or motor consisting of a hollow sphere of magnetic material, field poles upon the inner surface of the sphere magnetically connected through the body thereof, and an armature mounted to revolve within the sphere between the poles, substantially as described.

5. A dynamo or motor having a frame cons sting of a hollow sphere of magnetic material, and field pole pieces upon theiunersurface of the sphere magnetically connected through the body thereof, said sphere being divisible to facilitate assembling the parts of the machine,substantially as described.

6. A dynamo or motor composed of a hollow spherical shell in two parts, the lower partor hemisphere having base and bracket bearings for the shaft integral therewith, the opposing field-magnets being attached to the two hemispheres, respectively, as set forth.

7. A dynamo or motor having a hollow spherical shell to constitute a. frame having within the field-magnet cores removably attached to the shells, substantially as set forth. 8. A dynamo or motor having a hollow spherical frame, field-magnets within said shell, having hemispherical pole-pieces, and a spherical armature-core, substantially as set forth.

9. A dynamo or motor having a frame composed of two hollow hemispheres secured together, field-magnets removably attached within and provided with hemispherical polepieces, and a spherical armature-core, substantially asset forth. 1

10. The combination of two hollow hemispherical shells constituting a frame for a dyv uamo or motor, joined together on a horizontal plane, a base and journal-bearing arms cast with the lower portion, a horizontal armature-shaft journaled in said arms, a removable field-magnet vertically disposed and attached to each hemisphere within, and a spherical armature core on said shaft, substantially as set forth.

In testimony whereof I aflix my signature, in presence of two witnesses, this 21st day of RAL STON O. KINTZING.

January, 1893.
