M. DEPREZ; ARMATURE FOR DYNAMO ELECTRIC MAGHINES.
No. 469,080. Patented Feb. 16,1892.
v I2; @M w Z UNITED STATES I PATENT OFFICE.
MAROEL DEPREZ, OF PARIS, FRANCE.
ARMATURE FOR DYNAMO-ELECTRIC MACHINES.
SPECIFICATION forming part of Letters Patent No. 469,080, dated February 16, 1892.
Application filed December-7, 1885. fierial No. 184,368. (No model.) Patented in France November '7, 1885, No. 172,138-
To all whom it may concern:
Be it known that I, MAROEL DEPREZ, a citizen of the Republic of France, residing at the city of Paris, France, have invented certain new and useful Improvements in Armatures for Dynamo Electric Machines, (for which I have obtained Letters Patent in France, No. 172,138, dated November 7, 1885,) of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.
In the ordinary construction of ring-armatures for dynamo-electric machines the armature-coils are wound directly upon the core, so as to form an integral part of the latter and practically inseparable from the same. This construction has the disadvantage that in the winding of the coils thewhole armature-ring must be handled, which in machines of great size is difficult and annoying. The winding must ordinarily be done by hand, and is therefore necessarily slow and expensive. A stillgreater disadvantage is found in the fact that if any portion of the coil becomes defective the whole armature must be dismounted, and it is necessary to closly inspect every part of the coil in order to detect and locate the defective portion.
It is the object of my invention to overcome these difficulties by constructing the armature-coil in separate sections, which may be slipped on and off the core without disturbing the remainder, and I accomplish my object by providing a series ofsegmental bobbins of insulating material and by placing a coil upon each bobbin before the latter is slipped upon the core, whereby I am enabled to manipulate each section of the coil of the armature as anindividual Whole and to wind the same in a suitable lathe or otherwise by machinery. I further improve the construction bymaking the bobbins of plastic insulating material such as glass, porcelain, earthenware, plaster-of-paris, and the like-which materials are both good insulators and also admit of forming the tubular portion of the bobbin curved to conform to the curve of the In addition to this the materials which I preferably employ and which I have named are refractory, and therefore not injured by sparks or by heating. 7
In the accompanying drawin s, which form a part of this specification, I have illustrated in Figure l a perspective of a segmental section of the core of my armature, and in Fig.
2 a like view of one of the bobbins made in accordance with my invention.
The core A is built up of frame like laminae, as shown, and as more fully described in my application, Serial No. 184,867, and a detailed description of the same is therefore not here required. For each segmental section of the core I provide a bobbin B, the main body of which is a tube curved to closely fit upon the core, and it terminates in two flanges O 0.
Upon the tubular portion of each bobbin is wound a coil F, the terminals of which are connected with the coils of the adjacent bobbins and with the commutator, as is usual in dynamo-electric machines.
The material which I use for the construction of the bobbins must be such as to enable me to mold the tubular portion of the same upon a curve corresponding to the curvature of the core, and for this purpose I use'by preference glass, porcelain, stone or earthen ware, or any similar material that is a good insulator and at the same time refractory, so as to resist the destructive action of sparks and heat; but in some cases I may also use ebonite, gutta-percha, or wood impregnated with or boiled in petroleum, molten paraffine, or any other suitable hydrocarbon; but the refractory materials hereinbefore mentioned are preferable.
Having now fully described my invention, I claim and desire to secure by Letters Patent- 1. In an armature for a dynamo-electric machine, the combination, with a segmentalring core, of a series of segmental bobbins of refractory insulating material fitting upon the core and an armature-coil upon each bobbin, substantially as described.
2. In an armature for a dynamo-electric machine, the combination of a laminated segmental core with a series of independent segmental bobbins of glass, substantially as described.
' In testimony whereof I affix my signature in 100 presence of two witnesses.
MARCEL DEPREZ.
