ARMATURE-CORE FOR DYNAMOS.
SPECIFICATION forming part of Letters Patent No. 390,301, dated October 2, 1888.
(No model.)
To all whom it may concern-r Be it known that I, \VARREN S. HILL, a citizen of the United States, residing at Boston, Suffolk county, Massachusetts, have invented certain new and useful Improvements in Armature-Cores, of which the following is aspecification.
My invention relates to armatnrecores for electric generators or motors; and it has for its object to improve and simplify the construction thereof and produce a core which shall prevent heating and the effects from side currents, and at the same time furnish good magnetic qualities; and to these ends my invention consists in a core constructed substantially as hereinafter set forth.
Referring to the accompanying drawings, Figure l is a side view, partly in section, of so much of a core as is necessary to illustrate my invention. Fig. 2 is a section of the same on the lines arof Fig. 1. i
In carrying out my invention I provide a series of disks, 1, preferably of cast-iron, having side flanges, 2, and preferably with a laterally-extending collar, 3. These disks are adapted to fit snugly by being driven or otherwise applied to the shaft 4 of the core, and any number may be arranged thereon, according to the size of the core desired. These disks, when placed in position, as shown in the drawings, provide recesses 5, in which is wire, 6, which preferably fills the recesses flush with the edge of the disks.
Between the coils of wire and the disks I place suitable insulating material, preferably of paper, and these may be in the form of rings 7, which fit accurately over the flanges 2, so as to extend between the sides of the coils and the disks, and other pieces of paper, 8, may be wound around the flanges, so as to properly insulate the core therefrom. \Vhen the recesses have been filled with wire, they may be covered with insulating material, 9, of any suitable substance, as paper, which will aid in maintaining the wire in position in the re cesses, as well as serve as insulating material; but if the core is to be wound with insulated wire this additional insulating material 9 is not absolutely necessary.
In order to provide means for ventilating this core, I form in the webs of the disks perforations 10, which furnish a passage for the free circulation of the air through the core be tween the coils and the shaft.
It will be observed that this core may be cheaply made, as all the disks may be cast from the same pattern, with the exception, perhaps, of the end disk, 11, which has to be provided with two disks for one side flange in order to furnish a bearing for the coils therein; and this may be done by forming one of the disks, as 12, without the side flange, 2, or by uniting two disks, as 12 and 13, by a single flange, 11. Upon the core made up as thus described may be wound in any suitable man nor the wire forming the coils of the armature; and I have not deemed it necessary to show any particular form of winding.
By this construction of the core I provide a very simple and cheap structure; but it is evident that it is a strong and rigid core. The parts, being united as set forth, are not liable to become loose or get out of place; and I am also enabled to avoid the heating effects due to the so-called Foucault currents, which are apt to circulate through the machine, not only producing heat, but interfering more or less with its magnetic qualities.
Having thus described niyinvention, what I claim isr 1. Anarmature-core composedof a series of disks having side flanges arranged to be secured upon a shaft, substantially as described.
2. An armature-core composed of a series of disks having side flanges and provided with collars adapted to fit snugly upon the support- 'ing-shaft, substantially as described.
3. An armature-core composed of ascries of disks having side flanges, forming recesses, and coils of iron wire secured in said recesses, substantially as described.
at. An armaturceore composed ofa series of disks having side flanges, the said disks being secured upon a shaft, coils of iron wire supported by said flanges, insulating material between the coils and the disks and flanges, and perforations through said flanges, substantially as described.
In testimony whereofl have signed my name to this specification in the presence of two subscribing witnesses.
\VARREN HILL.
