DYNAMO ELECTRIC MACHINE.

'UNITED STATES PATENT OFFICE;
CHARLES A. HUSSEY, OF NEW YORK, N. Y., ASSIGNOR TO THE HUSSEY ELECTRIC COMPANY, OF SAME PLACE.
DYNAMO-ELECTRIC MACHINE.
SPECIFICATION forming part of Letters Patent No. 253,387, dated February 7, 1882.
Application filed August 31, 1881.
T 0 all whom it may concern Be it known that 1, CHARLES A. HUssnY, of New York, in the county and State of New York, have invented certain new and useful Improvements in Dynamo-Electric Machines, of which the following is a specification.
My improvements consist in a field-magnet for a dynamo-electric machine, composed of corresponding arc-shaped principal or main portions and intervening portions made continuous with said principal or main portions wound with wire and sufficiently offset from the main arc-shaped portions that when a proper quantity of wire is wound on them it will on the interior be approximately coincident with the interior surfaces of the main arc-shaped portions.
The improvements further consist in the combination, with such a field-magnet, of an armature composed of a core wound lengthwise with wire arranged within the same. This armature, when rotated, will travel before the poles or consequent points, as also before the entire length of the field-magnet, and hence it will move through the entire field of force. The dynamo-electric machine coinprisin g such a field-magnet will be cheaper, more compact, and lighter than one made in the ordinary way, because it will have a lighter and less bulky core and less wire thereon.
In the accompanying drawings, Figure I is a-perspective view of a dynamo-electric machine embodying my improvements. Fig. 2 is a transverse section of the same. Fig. 3 is an edge view, on a smaller scale, of the core of thefield-magnetandwire wound thereon. Fig. 4 is a perspective view illustrative of the winding of wire on the field-magnet, and Fig. 5 represents an end view of the armature-core and appurtenances.
Similar letters of reference designate corresponding parts in all the figures.
A A designate the core of the field-magnet, which consists of opposite corresponding principal or main portions, A, and intervening portions A, made continuous with the principal or main portions wound with insulated wire A and sufficiently ofiset that the interior surface of the wire will be approximately coinci- (No model.)
dent with the interior of the main portions of the magnet. The intervening portions A may be arc-shaped, or they may be perfectly flat and straight, as shown. This core may be of cast-iron or other suitable material. The insulated wire is wound on them, so as to form poles or consequent points of the main portions A of the core of the magnet. The method of winding the wire is fully illustrated in Fig. 3. If'desirabie, however, the wire may be wound in reverse directions from the center toward each end of the intervening portions A of the magnet-core. The wire may be retained in place laterally by pins A". As here shown, the field-magnet is arranged so that one of the intervening portions A is at the top or uppermost portion, and the other is at the bottom or lowermost portion of the said field-magnet, and it is supported by means of two feet, A secured to its exterior and to a base-piece, B, by screws or bolts to.
C C designate an armature consisting of a metal core, C, and insulated wire C, wound thereon. The core consists of a number of thin plates of wrought-iron or other suitable material. Its shape is that of a number of coincident arcs of a circle and a number of intervening coincident and concentric arcs of a circle of larger radii connected to the former by approximately radial portions. The construction of the armature-core is clearly shown in Fig. 5. The insulated wire is wound over the smallerarcs andthrough the hollow interior, and when in place its exterior is approximately coincident with the exterior of the larger arcs. The coils of wire thus produced extend in the same direction, and the inner end of one is connected with the outer end of the next throughout the armature, loops being thus formed which are connected by leading-wires C with the plates of a commutator, D, mounted on the exteriorof the shaft C of the armature. The plates of which the armature-core is composed may be connected to spiders, which in turn are connected with a hub fitting the said shaft. This shaft is supported in hearings in spiders E, which are secured by screws 1) to the ends or edges of the core of the field-magnet. The leading-wires C pass through a bushing, F, of insulating material, which is afiixed to the shaft U and fits in one of the bearings in the spiders E.
G designates lubricators for the hearings in the spiders E.
The shaft 0 may be driven by means of a belt applied to a pulley, 0 mounted on said shaft.
G G designate brushes, which are supported in posts G and bear on the commutator. The posts G3 are affixed to an annular plate, H, but are insulated therefrom by washers or gaskets oi'insulating material. The annular plate H is provided with concentric slots 0, through which pass screwsf, which screw into arms I, which are mounted on the spider E which is nearer to the comm ntator. By loosening these screws the plate H may be turned to adjust both the brushes in unison, and by subsequently tightening the screws the brushes may be secured in the position to which they are adjusted.
One end of the wire of the field-magnetnamely, the end g, Fig. 2.is connected to a binding-post, J, and the other end ofthe wircnamely, the end h, Fig. 2-is connected to the brush G The brush G is connected by a wire to the binding-post J. These binding"- posts, when the base-piece B is made of metal, are insulated therefrom by washers or gaskets of insulating material. Wires K lead from the binding-posts J J to conduct off the current of electricity generated by the machine.
The armature, when rotated, travels before the poles or consequent points, as also the whole length of the field-magnet. Hence it moves throughout the entire field of force and very powerful electric currents are generated.
As the core of the field-magnet is very light and the amount of wire used is very small, I producebymyimprovements a machine which, for its power, is exceedingly cheap, light, and compact.
What I claim as my invention, and desire to secure by Letters Patent, is-
1. A field-magnet for a dynamo-electric machine, composed of corresponding principal or main arc-shaped portions and intervening portions made continuous with the said principal or main portions wound with wire and sufficiently oflset from the main arc-shaped portions that when a proper quantity of wire is wound on them it will on the interior be approximately coincident with the interior surface of the main arcshaped portions, substantially as specified.
2. The field-magnet composed of the corresponding arc-shaped portions A, the intervening offset portions made continuous with said arc-shaped portions A, the wire A and the pins A substantially as specified.
3. In a dynamoelectric machine, the combination, with a field-magnet composed of corresponding principal or main arc-shaped portions and intervening offset portions madc continuous with said principal or main portions wound with wire, of an armature arranged to rotate within the same and consisting of a core wound longitudinally with wire, substantially as specified.
