This company uses field wireinsulated with a layer of asbestos and a single cotton cover-ing to hold the asbestos on. One notable thing about all the coil winding apparatusin this shop is that no wood forms are used. All forms aremetal, and hence have practically no wear, hence there isnot the danger of misfit coils due to the wear of the the use of metal entirely it is easier to design ap-.

The tension of the tape inrunning oflf the spool i^: regulated by the thumb nut on theend of its spindle. The friction drive on these coil windersis of interest, as it is the result of an accidental discovery,and is not likely to be thought of as practical by one never paratus which can be worked rapidly and conveniently, andthe danger of abrasion of insulation is no greater if cornersare properly rounded. With power on the armature coilmachines now run by hand crank, it is thought that a mancan easily wind coils for two (198-coil) armatures in a present a man, with the assistance of a boy to turn, and July 6, 1901.] STREET RAILWAY JOURNAL, 5 who divides his time between two neighboring machines,can wind 150 coils per day. The boy working the G. coil winder (Fig. 5) will turn off 350 to 400 coils perday. After the coils ar
