UNITED STATES PATENT OFFICE.
CHARLES J. VAN DEPOELE, OF CHICAGO, ILLINOIS.
DYNAMO-ELECTRIC MACHINE.
SPECIFICATION forming part of Letters Patent No. 259,061, dated June 6, 1882.
(No model.)
To all whom it may concern:
Be it known that I, OHAs. J. VAN DEPOELE, of Chicago, in the county of Cool; and State of Illinois, have invented an Improvement in Dynamo-Electric Machines, of which the following is a specification.
My invention consists in a new construction of the armature for dynamoelectrio machines, and comprises a new mode of constructing, winding, and connecting the armature-coils; also, of new combinations of the various parts constituting my armature, all as fully set forth in the following specification, and specifically pointed out in the claims, reference being bad to the annexed drawings, in which Figure 1 is a vertical longitudinal section of my armature, showing construction of frame thereof. Fig. 2 is an end view of armatureframe. Fig. 3 is a vertical longitudinal section, showing the connection of two opposite coils. Fig. etis onehalt'ofa crossscction, showing connection ofcoils with commutator. Fig. 5 is a similar cross-section, showing connection ofcoils with the insulated ring. Fig. 6 is a diagram cross-section, showing mode of winding and connecting the wire upon the cores. Fig. 7 shows in an end view thecommutator and collecting-brushes. Fi 8 is a detached perspective view of one of the coils.
In the drawings, A is the shaft of the armature, to which are secured the two brass disks B B.
O O are a number of coils arranged cylindrically around the shaft and stepped with their ends into recesses a, formed on the inner sides of the brass disks B B.
I) are soft-iron rods, also placed cylindrically around the shaft in the intervals between the coils, with their ends passing out through the disks and provided with screw-nuts ff.
F is a metal ring insulated from the shaft, but firmly secured thereto.
G is a commutator, also secured to the shaft, and divided in sections corresponding to the number of coils in the armature.
H is the top collector; H, the bottom collector.
I and I are brushes.
The construction of the coils G is as follows: bis the inner core, made of a thin soft-iron plate, bent or doubled upon itself, as represented in Fig. 1, leaving a central opening, 0. The point at which the free ends of the thin iron plate are brought together is immaterial, as it may be upon either side instead of at one end, as shown in the drawings. (1 (Z are polefaces, and consist of thin soft-iron plates secured to each side of the core I) by means of rivets c, passing through the opening 0 of the core. The face-plates d d are perforated and theirendsfitted to enter into the recesses aofthe disks, as shown. The core b, with the plates (1 d, thus forms a spool upon which the wire is wound in the following manner: The spool being attached to some suitable machine for winding, one layer of wire is wound upon the core and then a thin plate of soft iron, insulated on both sides, is wrapped around it. Then another layer of wire is wound over it, with another plate of insulated soft iron wrapped on top of it, and so on, one layer of wire alternating with a layer of insulated soft-iron plate until the required amount of wire is wound on, the different layers of wire being formed of the same continuous wire.
It is evident that ono or more bent plates or cores .an be used in connection with the face-plates d, and one or more layers of wire to form a magnet, without departing from the spirit of my invention.
For mounting the armature the coils are placed vertically upon the inner side otone of the disks B, with the coils stepped into the recess a, between the rods D. Then the other disk, A, is slipped on top and the nuts fffirinly screwed down upon the rods D. The shaft B can now be passed through the disks and the latter secured thereon by means of setscrews. Next, all the inside endsol the wires are con nected to the ring F, and all the outside ends of the same are connected to a corresponding section of the commutator Gr.
Having thus described all the different parts of my armature, I will now proceed to explain its action while revolving in its field of force, where it belongs.
On examining Fig. 7 it will be seen that one half of the sections of the commutator are in connection with the top collector, H, through its brushes I, while the other half of the commutator is in connection with the lower collector, 11 through its brushes I; and if we connect now, for instance, the positive pole ofa battery or other source of electricity to the collector H, and the negative pole to the collector H, the current will flow through one half of the coils of the armature in the same direction to the ring F and pass over to the other halfof the armature-coils, through which it passes in the same direction, (see Fig. 6,) and is then finally collected by the brushes I and collector H, and completes its circuit to the negative pole of said battery. In Fig. 6 the positive pole of the armature will then be at and the negative pole at P-, while N and N mark the neutral points. Now, on revolving the armature in a field of force of ordinary construction and connecting the same properly with the coils of said field, a continuous current is produced.
I am aware that it is not new to construct electro-magnets of alternate layers of wire and iron tubes, or layers of wire and layers of transverse iron rods, and I do not claim such construction. In my invention iron plates are bent to form smooth surfaces on which the wire is wound, and each iron plate fits closely around and forms a perfect binding for the layer of wire beneath it. This construction renders the winding of the magnets very easy compared with that style of magnet in which numerous transverse iron rods or wires are used.
What I claim is- 1. In an armature, a series of sectional cores, each composed of thin sheet-iron plates, folded upon themselves, in combination with layers of wire wound between said metal plates, substantially as described.
2. In an armature for a dynamo-electric machine, a magnetic section consisting of a sheetiron core bent or doubled upon itself and secured to pole-faces of the same material and coils of wire wound upon said core, substanscribed.
