GUSTAV PFANNKUOHE, OF CLEVELAND, OHIO.
ELECTRICAL CONVERTER.
QPECIFICA'IION forming part of Letters Patent No. 429,583, dated June 3, 1890.
Application filed September 28, 1889. Serial No. 325,401. (No model.)
To all whom it may concern:
Be it known that I, GUSTAV PFANNKUCHE, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Converters; 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 saine.
My invention relates to an improvement in converters; and it consists in certain features of construction and combinations of parts, as
.will be hereinafter described, and pointed out in the claims.
In the accompanying drawings, Figure 1 is a view, partly in side elevation, of my improved converter supported on a reel. Fig. 2 is a similar view, the reel being dispensed with. Fig. 3 is a transverse view of the ironwire core and the primary and secondary coils.
A represents a reel, which may be made of wood or metal. Each side or half of the reel consists of a hub 13, from which radiates'any desired number of spokes O, which are each provided with a series of holes. Strips D, of wood, hard rubber, or fiber, are inserted through the holes a in the spokes, and are secured against displacement by means of pins or keys I), inserted through their outer and projecting ends. Upon the strips or distancepieces D is wound the iron wire composing section E of the core. Strips or distancepiecesD are then inserted and secured within the holes a in the spokes and the iron wire forming section F of the core is wound upon them. In the same manner the core is built up of any desired number of sections of wire, the outer section being secured by the strips D.
It will be observed that the core, when formed in the manner shown, is thoroughly ventilated, its outer surfaces being exposed to the air and any desired number of ventilating-spaces D formed between the several superposed coils or sections. The reel forms a convenient holder or frame for supporting the converter or securing it in place.
The iron wire of which the core is made may be naked iron wire suitably varnished, or it may consist of cotton-covered wire or naked iron wire having its successive layers insulated from each other by strips of cotton or other material.
Around the core are Wound the primary and secondary coils J and J, which are insulated from each other and also from the iron core by ventilatingspaces formed in the following manner: Upon the corners of the iron core are placed the corner-pads I, which are made of vulcanized fiber, cotton cloth, or any suitable material, and around the pads is wound the coarse copper wire J, which constitutes the secondary coil of the converter,while the primary coil maybe composed of any number of superposed layers of wire J. I prefer to dispose the conductors ofthe secondary and primary coils in such manner that the secondary coil shall consist of a single layer only of coarsewire and thereby insure it the best possible insulation and ventilation. By separating the secondary coil from the core by means of the corner-pads I produce ventilating-spaces K between the outer surfaces of the core and the inner surfaces of the secondary coil. Upon the corners of the secondary coil are placed insulating corner-pads I,upon which is wound the fine wire constituting the primary coil J, the inner surfaces of which are insulated from the secondary coil by the intervening ventilating-spaces M.
By winding the core and the secondary and primary coils in the manner described all parts of the converter are exposed to inspection and are accessible for repairs. Again, the intervening spaces formed between the sections of the core,between the core and secondary coil, and between the secondary and primary coil, insure visible insulation of the parts and also provide for perfect ventilation and the carrying off of the heat developed in the use of the converter, thereby obviating the danger of the burning out of the converter.
Instead of winding the core on a reel, as illustrated in Fig. 1, it may be wound on distance-pieces and the latter connected by steel pins N, as illustrated in Fig. 2.
It is evident that the core may be widely varied in form, that it maybe made square or round or of other shape in cross-section, and that it may be made of four, six, eight, or any desired number of sides, that the secondary coil may be coupled up in series or in any other desired manner, and, further, that the converter may be varied in its details of construction, all without involving a departure from the spirit or scope of my invention,and hence I would have it understood. that I do not restrict myself to the particular form and construction of parts shown and described; but,
Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a converter, the eombinatiomwith an annular core, of primary and secondary coils wound transversely around the core, and corner-pads inserted between the coils and between the coils and core, thereby forming ventilating-spaces between the core and coils and between the coils, substantially as set forth.
2. In a converter, the combination, with a core, of distance-pieces inserted between the superposed layers or sections of the core, forming' intervening ventilating-s ntces, and rods or spokes for securing the ends of the distance-pieces against displacement, substantially as set forth.
3. In a converter, the combination, with a reel provided with detachable distance-pieces,
of corner-pads on the corners of the core, and
a secondary coil wound upon the corner-pads, substantially as set forth.
5. In a converter, the combination, with a core provided with ventilating-spaces extending transversely through it, of a secondary coil encircling the core, and insulating cornerpads for forming ventilating-spaces between the core and secondary coil, substantially as set forth.
In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
GUSTAV PFANNKUCIIE.
