The rear endis equipped with a heavy bumper which effectually takesall shocks, and protects the lift platform. A drawbar attach-ment also is provided which enables the truck to be used asa light duty tractor. An automatic brake and circuit breaker application, four-wheel steer, single reduction worm drive of the power axleand easy accessibility of batteries, lifting, driving and con-trol mechanism are features of the truck. It will operate inintersecting aisles 60 in. wide. The extreme turning radius, outside point, is 7 ft. 10 I. T. C. Self-Loading Electric Truck By folding the foot pedal and steering handle into a verti-cal position, the overall length is shortened for use on ele-vators. The length is 102 in. overall or 9\lA in. with the January, 1921 RAILWAY MECHANICAL ENGINEER 53 step raised. The width is 36 in. overall and the height oversteering shaft head 51 in. Either alkaline or lead batteriesare used. The controller is of the drum type with threespeeds forward and three reverse. The new truck has been subjected to rigid tests underactual operating conditions, and promises enduring servicedue to its all-steel construction, low center of gravity, andgeneral compactness and ruggedness. Taper Attachment Applied to Boring Mill FOR turning and boring tapers approaching nearly a hori-zontal line to which swiveling the head is not adaptable,a taper turning and boring attachment has been de-signed for use on boring mills manufactured by the CincinnatiPlaner Company, Cincinnat
