A very noticeable feature of this tool room is theabsence of belts and also the simplicity of the headstockarrangement effected by the use of the variable-speed motor. The following engravings present views of a home-madeapplication of motor driving to a large Bement-Miles wheellathe in a prominent railroad repair shop. The motor used isa constant-speed General Electric motor, and with the drivingcone pulley, it is mounted upon a platform of boiler plate, sup-ported by cast-iron pillars bolted to the headstock. This is aconvenient method of adapting an old tool to motor driving—the principal criticism In this case is the lack of a means ofeasily raising the drive cone
