Jlhe invention consists primarily in the method or art of making insulated wire consisting in winding '1 cotton sliver spirally about a conductor wire, with the edges overlapping, compacting said sliver upon the wire, windinga strand of flexible, absorbent cessive",conVO111ti6ns thereof within said sliver [while it is :comp'acted, said strand being wound a ata'difierent pitch" than "that at which said sliver is. wound, and thereafter saturating oivim regnatin'g said. sliver, and
said "strand" wit a viscous. composition whereby the insulating property is increased, the completed wir'e'is waterproofed, and said other novel steps'and practices as are hereinafter set forth and described and more particularly pointed out in'theclaims hereto ap endeda j I c efe'rr ng to'the draw Fi 1 is aside elevation of a machine binding to a. conductor and Fig. 2 ,illustr tesu an apparatus used in the ering for the wire withf asp viscous composition. 5 q r t Like'letters refer to like parts in both of said views: [In thepractice of the method or art of my invention, a continuous strand of acon-' ductor wire ,a' is passed through a bath of altum or other the rollersc' to a rew1ndingreel (not shown). "a continuous strip ofcure' continuity of this-cover and substan-, tially the? same thickness thereof throughout. This. liver is applied by means of a-rotating platform 0 ada ted to carry a container for; the sliver, t through-this platform axially thereof, After the application of the wire with the sliver thereon passes through and embedding 'suef 1 e wire a passing vertically sliver to the wire, the

Preferably a plurality of independent to permit the use of a fairlywide sliver confined at a number of different points by these} threads or cords The variance in he'number' of convolutions and of the resulting pitch of thesaid threads or cords and of the sliver, causes theformer to intercept the line' of the lap joint of succeeding convolutlons of the. sliver, thus tending to minimize a tendency towardthe unwinding of the sliver, either. while the wire is in process orafter ,itvhas been completedv and is in use.
manner above described by the thread or cord j, the,wire with'its covering iscpassed through'a tank kcontaining a bath of viscous insulating, adhesive and waterproof material, such as the asphaltum composition ordinarilyu sed in makingvinsu lated wire. Thef wire after thes'setting of this' composition fz-is waxed and, passed through polishing and; finishing" irons' giving the desired final'finishgthsreto. v
7 By reason'fof-the'.application of adhesive to the wire {before Wrapping the sliver spirally thereupon, this sliver [will be firmly bonded to 'thejfwire' so as to resist dis'p'lac'ement bythe compressing .or compacting horns, even though the se, horii' do not have rotary movement. p I I t e. cotton i r s 1,11 the 'asphaltuin sliver,

In this manner, 'I am enabled by afsubstanr I or continuous operation, to apply both the'cotton sliver and the bind-i ing thread or cord to the wire, thereby gain;
iiig the'advantage over the present methods of avoiding t e necessity for passing the wires successively through a machine for wrapping this sliver about the wire, and a machine for applying a cover thereto.
Theessential characteristic of the method orart of my present invention is the application of the binding threads or cords at a lesser or lower pitch than that at which the sliver is applied to the wire,'thus avoiding he possibility of the thread or cord being unwound simultaneously w ith the sliver b reason of'the fact that the binding thread or cords. intercept the lap of succeeding convolutions of the sliver- Having described the invention, what I claim as new and desire to have protected by Letters Patent is z--.- 1 a 1.
