V. 11 type and the Edison the 59 cell A-4 or is a hinged cover in the truck deck, which permitsof quickly changing the battery if it is desired to use thetruck continuously. Another advantage of the hingedcover is that it permits of easy inspection of the charging receptacle of the Anderson type is provided,and there is an extra charging receptacle at the driversplatform for convenient use when charging the battery onthe truck. The controller is of the drum type and is mounted onthe dash. Owing to the fact that a higher voltage is used. Trr truck tying loadt <l platfoi Detail of lifting jacks and their chain-operating mechanism I han the conventional industrial truck voltage, the oper-ating current is comparatively low, and this, together withwide controller fingers, reduces the wear of these a safety feature arrangements are made so that it isimpossible to move the controller handle unless the oper-ator is in the driving position. The speed range, lightis | 2 to 10 and with full load ■/■< to 7 Resist-ance is used in the main circuit only on the low speed, andon the high and intermediate speeds there is therefore noloss of current by resistance. The frame is provided with stake pockets which arc ofsteel, hot riveted to the inside of the frame, giving flushIfame sides. Stakes can be conveniently carried in the rear of the dash when not in use. An automat iplej is furnished with the truck. This has 2x8 in. double act-ing helical springs to prevent shocks when
