plurality ot insulated strands arranged, one outside the other, as is vinost clearly shown in Fig. 3. The "trands lforining the inner twothirds clE e ch section are connected to forni a stranded conductor connnon to all the sections. ''.)ne terminal oly this conductor is shown entering section c1 at l in Figs. 2 and 3. This conductor extends through all the sections in series, ii'xcluding the strands l'orining the inner two-thirds oll each section, and has its other end at section c" at the point 2. This conductor may be given a twist at its niiddle point between sections c and c, as indicated at' i5, so that the outer strand oll this conductor on one side olA t he twist becoines the inner st ind on the other side ol the twist, and the l ridilages indgiced in all the strands ot' the condneior are initialized. On leaving the seci i at the point 2, this conductor divides j into two equal parts,one part passing tln'tnig'li the outer strands in series with the /ns c, cf and c, and the other partV passthrough the outer strands in series of the sections ff. ci and c". lhus two other stranded conductors are lorined,---one entering section 1:1 at fi. and leavin;r section c atA 5, while i the other enters section at (El, and leaves secl tion c at 'ihe ends 5 and 7 are connected l fetlicr, as clearly shown in Fig. fi. These 'info coinlnctors, each ol which is ol' hall the i cross-section oly the conductor lirst described, are connected in parallel with each other, and in series with the lirst ronductr'ir. [n thisl manner the six sections are ei i'1n .cted to,1 torni astran led conductor with nine ell'ectl ire tin and with a cross-section equal to two-thirds the cross-section ol'L each section. ,t l l l l l l Ot lier coinbiinitions of connections may be employed to secure otln r ratios ol the ninnber ol turns and ol' cross-section, in accord-` ance in tlzA the principles above explained. Accord "fly, lV do not desire to liinit myself to icular construction and arrangement s here shown, but aiin in the appended l l i l ctor coininon to all of said sions and the remaining strands beingconnected to forni a pluralityv of conductors each corninon to a portion only ot' said sections.

f) A winding ior electrical apimratus coniprising a plurality of sections each composed ot' a plurality of insulated strands arranged one outside the otlier, a porti .n olz the strands ol each :ection beingl connected to forni. stranded condncttn' colninon to all ol` said sections and the remainingl strands being connected to Forni a plurality ol conductors each connnon to a portion only olA said sec!- tions said last inei'itioned conductors being connected in parallel with each other and in series with the lirst mentioned conductor.

3. A winding lior electrical apparatus coinprisingl a plurality of .sections each composed ol' a plurality oli insulated strands otI equal cross-section arranged one outside the other, the ,er later portion ot the strands ol4 each section being' connected to forni a stranded conductor coinnion to all olI said sections and the remaining strands liieingv connected to lforin a plurality of conductors each coi'ninon to a portion only of said sections, said last nien-- tioned coinluctors being: connected in parallel with each other and in series with the lirst mentioned conductor.

Li. A winding for electrical apparatus coniprising a plurality' ol sections each composed of a pluralit)r otl inf-inlated strands arrainged one outside the otl1cr,`tlie inner strands ol" ieach sec-tion being connected to lorin a stranded conductor connnon to all ol said sections and the outer strands being connected to torni a pluralit)v ol' conductors each connnon to a portion onlyr ot said sections.

5. A winding lor electrical apparatus coniprising a pluralit f' ol: sections er. h composed of a plurality olz insulated strands arranged One outside the other, the inner strands ol each section being connectixi to lorin a stranded conductor coininon to all ol' said sections and the outer strands being connected to lorm a plurality ol' conductors each common to a portion only ol said sections, the lirst mentioned conductor being' twisted iinte'iinediate its ends so that the outside strand onl one side ot the tu is the inside strand on the other side of the twist. ln witness whereof, l have hereunto my hand this 30th da)Y of' October, i906.
