Specification ofLe'tters Patent. Patented June 20, 19 22.
' Application filed February 20, 1920. Serial No. 360,175.
.Be it known that I, JOSEPH P. Davina, a citizen of the United States, residlng at Buffalo, in the county of Erie and State of New York, have-invented a new and useful Improvement in Apparatus for Drying the Covering of Electrical Conductors or the like, of which the following is a specification.
This invention relates to apparatus for removing moisture from the covering of cables, wire or other electrical conductors or analogous devices. 7 v
The objects of this invention are to provide an apparatus of this kind by means of which a coil or mass of covered wire or cable can be quickly heated by means of an electric current passing through'the same, to effect a rapid drying of the covering and which is so constructed that the ends of the conductor or conductors to be dried can be readily connected with and disconnected from a suitable supply of electric current;
also to improve methods and apparatus of this kind in other respects hereinafter specified. v I
In the accompanying drawings:
Fig. l is a central sectional elevation of an apparatus embodying the invention, by means of which the process forming a part of this invention may be carried out.
Fig. 2 is a sectional plan view thereof on line 2-2, Fig. 1.
Fig. 3 is a similar sectional plan view thereof on an enlarged scale showing means for making electrical connections.
The apparatus disclosed is primarily intended for use in drying the paper covering which is generally first placed upon the wires, cables or other electrical conductors, and which after being thoroughly dried, is impregnated with an insulating material. The invention, however, may be used for drying covering other than paper.
In the apparatus shown A represents a vacuum or drying chamber which may be of any suitable form, that shown being substantially cylindrical and open at the top to permit the drums on which the covered conductor is wound to be placed into the chamber. The upper portion of the chamber is closed by means of a cover B which may be held in place on the drying chamber by the usual bolts 5 or the like. The air may be exhausted from the drying chamber through a pipe C. D represents the conductor projecting beyond the drums.
. in order to conduct electricity to the conduc'tors wound on the drums, suitable bus bars or other connectors are arranged with,-
bars are slidable relatively to the supporting brackets therefor, this being accomplished by means of. pins Gr' extending through the brackets and through the. bus
drums on which the covered wire, cable or Y other conductor 1s wound, the ends 03 of the bars, and springs g are provided which press the bus barsof each pair yieldingly toward each other, the springs shown being arranged around the pin G. By means of this construction, if a wire d is forced between the bus bars, the springs will yieldingly-press the bars into engagement with the wire and thus form a good contact or connection through which the-current may be conducted to the wires. The bus bars are connected to suitable conductors g which in the construction shown extend through insulating bushings g inthe wall of the drying chamber. The advantages of the bus bar construction shown are that any number of conductors may. be placed between thebus bars and the conductors may be connected to the bus bars at any desired port-ions thereof. Other means may be provided for supplying electric current to the conductors on the drums. The current flowing to the bus bars may be controlled by any suitable well known means so that the reason that the heat is applied directly to the conductors, and a great saving in time required to dry the covering is also effected by means of the apparatus. The use of vacuum for removing moisture also greatly facilitates the drying of the wire covering.
I claim as my invention: 7 1,. In an apparatus for drying the covering of electrical conductors, the combinaextend substantially throughout the length of said chamber and to which a plurality of said conductors may be connected for passing a current of electricity through said conductors for heating the same, and a single pair of terminals extending through the chamber walls for supplying current to said connecting means.
3. In an apparatus for drying the covering of electrical conductors, consisting of a drying chamber adapted to receive a drum on which a covered conductor is wound, means through which air may be exhausted from said chamber, and electrical connectors in said chamber and including two members, one of which is yieldingly pressed toward the other member and between which the ends of the conductors may be yieldingly held for causing the conductor to be heated by a current of electricity passing through the same. i 7
4. in an apparatus for drying the covering of electrical conductors, consisting of a. drying chamber adapted to receive a drum on which -a covered conductor is wound, means through which air may be exhausted from said chamber, and electrical connectors-in said chamber including bus bars extending substantially throughout the height oi the chamber, and to which the ends'of the conductors may :be connectedfor heat ing the conductors by a current of electricity flowing through the same.
5. In an apparatus fordrying the covering or electrical conductors, consisting of a drying chamber adapted to receive a drum on which a covered conductor is wound, means through which air may be exhausted from said chamber, and electrical connectors in said chamber including bus bELIS'GX- I tending substantially throughout the height of the chamber, each bus bar comprising two members yieldingly pressed toward each other and between which the ends of the conductor may be yieldingly held for causing the conductor to be heated by a current of electricity passing through the same. i
lVitness my hand this 16th day of January, 1920.
