UNITED STATES PATENT OFFICE.
IVARREN S. BELDING, OF ENGLEIVOOD, ASSIGNOR TO THE BELDING MOTOR AND MANUFACTURING COMPANY, OF CHICAGO, ILLINOIS.
ARMATURE-PLATE.
SPECIFICATION forming part of Letters Patent No. 415,695, dated November 26, 1889.
Application filed July '7, 1888. Serial No. 279,313. (No model.)
To all whom it may concern.-
Be it known that I, WVARREN S. BELDING, a citizen of the United States, residing at Englewood, in the county of Cook and State of lilinois, have invented certain new and useful Improvements in Plates for Armatures; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification. This invention relates more particularly to plates to be used in the construction of segmental sections of armatures, which sections are to be built up and wound and united to form the complete ring on cylinder after winding. It has been found desirable to construct the armature-ring in segments in order that the winding may be more easily accomplished and that a coil which has been rendered defective by use may be more easily removed and replaced.
In the accompanying drawings, Figure 1 is a View of two of my improved plates disconnected, Fig. 2 is an end View of a completed ring formed of the plates. Fig. 3 shows a modification of the form of plate shown in the preceding figures. Fig. 4 shows the side of a completed ring without the coils.
Referringto Figs. 1 and 2, A A are plates of such dimensions and form as that they will 3 5 fit together end to end and constitute a complete circle. The meeting ends are so formed as to interlock and form a joint, by which the plates are held to each other. Each plate in Fig. 1 has a projection A at its ends, extending inwardly or outwardly in a line passing through the center of the circle of which the plate forms a part. I prefer to form each such projection with parallel sides, so that its outer portion is of the same Width as its inner portion, but it may be of other shape;
and I prefer to form one of the said projections to extend toward and the other from the center of the circle. The special advantage of this latter feature will be stated below. Between each such projection and the body of the plate is a notch A of sufficient width to receive the projection A on the end of the plat-e A,which is brought into j uxtaposition to it. Said notches are best made with parallel sides; but they may be of other shape, so long as they are as wide at their outer portion as the widest portion of said proj ections, in order that said notches may receive said projections when the said sections are moved toward or upon each other 011 a line passing through the ends of both sections. The plates A may or may not have polar extensions A. By making each plate for the complete ring a half or other aliquot part of the circle all the plates may be identical and cut from the sheet of metal in the same die.
I11 building the half of the armature the plates are placed side by side to make the desired thickness. Sheets of insulation material cut in the die in which the plates are cut may be placed between the plates, and the plates may be held together temporarily by any suitable means. The similar ends of the plates and the insulated sheets are laid upon each other and the ends are made even with each other, none being extended beyond the rest to make spaces between the ends. hen thus massed and temporarily held together, the bobbin-spaces B of the section are wound 8c with wire to form the coils C. \Vhen the coils have been thus wound, they hold the plates of the section together. The two halves may now be easily united by sliding one sidewise upon the other, so that the projections A on one half enter the notches A on the other half; or the two halves may be slid endwise upon each other, the projection A sliding in the channels formed by the notches A The ring or cylinder is now ready to be 0 mounted upon a shaft by means of a spider. Holes D between the bobbin-spaces in the plates form continuous holes between the coils through the sections for the reception of bolts used to bind the spider or spiders to the armature.
In Fig. 3 the ends of the plates look by dovetailing, a projection E being formed on one end and a corresponding notch being formed on the other. The halves of the armaroo ture builtof these plates must be moved upon each other in the direction of the axis, while those built of the plates shown in Fig. 1 may be moved upon each other in the direction of the axis and also in a direction transverse to the axis. The latter mode is preferable, because the sections are not so apt to bind upon each other before each is in place. In the form shown in Fig. 1 each projection A merely enters the notch in the end of the plate which is to stand opposite to it in the complete arm ature, while in the other form the proj ections E must move parallel to the axis of the arma ture through the channel formed by the notches E, and, as the dovetailing must fit closely, care must be exercised to get the ends of the plates so even as to allow the sections to move readily upon each other. It is to be observed that in neither form do a portion of the plates extend beyond the others, so as to' leave spaces for the projecting ends of the plates of the opposite section to enter. This I consider an important improvement.
I have found in practice that it is difficult to interlock the sections by means of the projecting ends. The ends of some of the plates are apt to turn sidewise sufficiently to prevent the meeting ends of the sections from intermeshin g readily, and if insulatioirsheets are used between the metal plates the ends of said sheets are apt to be met and pushed inwardlyby the ends of the metal plates of the opposite section. In consequence of this the insulation-sheets must be made thick. By the use of my improved plates no such trouble is met with in. using either the metal plates or the insulation-sheets, and the insulation-sheets may be cut of thin sheets, whereby the thickness and cost of the armature are reduced.
I claim as my invention- 1. A sheet'metal armature-plate forming a portion of a circle and having its ends provided with projections and with notches as wide at their inner portions as the widest portion of said projections, and formed to interlock with the ends of a similar plate, substantially as and for the purpose set forth.
