DYNAMO-ELECTRIC MACHINE.
SPECIFICATION forming part of Letters Patent No. 406,599, dated July 9, 1889.
Application filed April 20, 1888. Renewed April 13, 1839. Serial No. 307,208. (No model.)
T0 (0% whom it may concern:
Be it known that I, WILLIAM L. SILVEY, a resident ofLima, in the county of Allen and State of Ohio, have invented certain new and useful Improvements in Armatures for Dynamo-Electric Machines, of which the following is my specification.
My invention relates to an improved c011- struction of the armatures of dynamo-electric machines; and it is the object in my pres ent invention to construct an armature that will be at once simple, cheap, durable, and very strong, without the necessity of complication of parts, as is generally employed by most makers.
Referring to the accompanying cuts,whicl are made a part hereof, in which similar letters of reference refer to similar parts throughout, Figure 1 is a perspective view of the complete armature without the wires, and Fig. 2 is a side view of the armature-spider B B and shaft A, on which the armaturerings D E are mounted. It will be observed that the armature-blanks E are of very thin sheet-iron,'having notches e stamped at regular intervals out of the inside, into which the brass spider B B is pushed. 'Each of these out iron blanks is separated from the ones adjacent to it by a paper blank of a corresponding size. Each end of the armature is faced by a heavier iron blank D, an inside view of which is shown in Fig. 3 and outside view in Fig. 4:. Fig. 5 is a side view of the stamped sheet-iron blanks. Fi 6 is a perspective view of the armature disjointed at its center, showing the arms of the spiderprojecting, with the armature-blanks of each half in place; and Fig. 7 is an upright perspective view of one of the spiders, showing the V-shapedends of the armature -wings, whose office is to assist in making the armature interlocking. The reason for this heavier plate is in order to have a solid surface for the lugs b to press against in order to keep the lighter blanks together.
The spiderB B is divided in its centerinto two parts, each of which is filled nearly full of the cut blanks and the two pressed together by clamps, at which time it is secured on the shaft by bolts 0 c. The great peculiarity of this spider is the peculiar construction of the blades. By looking closely at Fig. 2 it will be observed that each alternate blade is longer than the other, whereas the blade which faces it is short. This continues entirely round the spider. Whenever there is a long blade on one side there is a short one on the oppositehalf of the spider. \Vhen the half-spider is filled with blanks there will be one-half of the wings which do not come flush with the surface, whereas the other half or each alternate wing will project a little above the surface. here the wingsare short on one half of the spider they are long on the other side, and the long Wing will press into the notches in the rings where the corresponding or short one is, and in this way the two halves are made interlocking, and are as strong as if the spider had been made of one solid piece throughout. This is the particular distinguishing feature of my armature. I sometimes use a V-shaped edge between the ends of the wings, the pointed one being the longer and the smaller one being cut away to correspond. In this case a still stronger joint may be made.
It will be observed by looking at Figs. 3 and 4: that the heavier iron blank D is grooved out on its inner side to make it light and relieve it of materiahwhich will entirely eliminate all danger from heating, which it would do unless this were done.
I11 case the armature is very large and it is not desirable to use wrought-iron for the two rings at the end of the armature, or Where the iron is hard or cast-iron containing alarge per cent. of carbon or of too large a bulk, which will cause the iron to heat, I prefer to make these end rings of brass or other nonmagnetic material; but I would not alter this form, and would not advise this change of metals, except the trouble from heat is so great as to endanger the insulation.
Having described my invention,wh at I claim as new, and wish to secure by Letters Patent in the United States, is
1. An armature for dynamo eleetric machines, consisting of two interlocking spiders B 15,011 which are mounted end plates D, one at each end, with numerous alternate blanks of sheet iron and paper pressed between them, and the whole mounted on a shaft, substantially as and for the purpose set forth.
2. In an armature for dynamo-electric ma chines, the supporting spiders B B, having the spider consistingofsoparable parts united each alternate Wing shorter than the other, together by \vedge-shzmm'l projeciions, as set IO whereby the Wings are made to interlock forth and described.
when the armatureblanks D E are mounted T V T 5 thereon,substantiall y as and for the purpose ILLIAM H In specified. XVitnesses:
An armature-spider [or supporting a R. CJVARNER, magnetic ring on which the wires are Wound, FRED NEILL.
