. Il giornale ferroviario di strada . rator non avrà difficoltà a fermarsi dove vuole. Questo piano è già in uso sulle macchine avvolgitrici a bobina di campo descritte più avanti. In Fig. i ilolio è stato appena avvolto tra i due bracci, trafila il filo da una bobina sullo sfondo, e gli stampi sono stati serrati, che danno una leggera torsione ai lati deloli. La distanza tra i bracci è regolabile conle viti di fissaggio mostrate. Questa regolazione con il cambio di matrici adatta la macchina per l'avvolgimento dei diversi tipi di bobine menzionati. Particolare attenzione dovrebbe essere rivolta ai tappi

. The Street railway journal . rator will have no difficulty in stoppingjust where he wishes. This plan is already in use on thefield coil winding machines described later. In Fig. i thecoil has just been wound between the two arms, drawingits wire from a spool in the background, and dies have beenclamped on, which give a slight twist to the sides of thecoils. The distance between the arms is adjustable withthe clamp screws shown. This adjustment with the changeof dies adapts the machine for the winding of the differentkinds of coils mentioned. Particular attention should becalled to the caps on the ends of the arms, which are ad-justed to form the groove into which the wire goes as itis wound. The width of the groove is, of course, varied tosuit the gage of the wire that is being wound. This widthof groove is adjusted before the machine is started by oneof the clamp screws seen on the arm, which adjusts thedistance to which the cap can be pushed in. By looseningthe other clamp screw on the arm the cap can be taken. FIG, 6.—ARMATURE COIL WINDER FOR WESTINGHOUSE49 MOTORS completed coils below it. This machine is comparativelysimple. To remove a coil after winding, the block on onecorner is loosened, and also one of the end clips. In Fig.3 the coil is just completed, and has the spring clips onready for handling. 4 STREET RAILWAY JOURNAL. [Vol. XVIIL No. i. The G. E. 800 motor armature coil winder is clearlyshown in Fig. 5. The winding is accomplished by a backand forth motion of the hand wheel. The coil is taken outof the winder by removing the caps around which the endsof the coil make the turn, and the coil then has the formseen in the coil on the table just in front of the hand wheel, Fig. 5. It is then spread to the form shown on the tableat the right of the hand wheel.
