When this cart is filled with turnings it is pickedup by the crane and carried away to be dumped outside. The large wheel lathe has two turret heads and its tailstock is moved by an independent motor. The control of thedriving motor is governed by a reversing controller and alsoby two snap switches mounted on the frame of the lathe closeto the operators position. One of these switches serves tostop the lathe instantly and the other to reduce to half-speedwhile the lathe tools are passing through hard spots. Thespeed of the Sellers lathe is 16 ft. per minute and the wheelsare turned with a J^-in. feed, using high-speed steel tools. Onemachinist and a helper turn about 10 pairs of wheels in aworking day of nine hours. The wheels are brought close to.
