PARSONS, ELECTRICAL FOREMAN In many instances it is necessary to operate cars ortrucks in parts of buildings or yards where power isnot available; for example, on an upper floor equippedwith a transfer table but without trolley wires or chan-nel rails, or in shops where the cars are jacked up andthe trucks moved elsewhere for overhauling. The following paragraphs describe a reel whose con-ductor is made alive, embodying such construction thatthe wire can be fed out as the car or truck leaves thetransfer table or elevator, and which can be wound InsulatorFiber ContactFingers. BUctTb By. Journal FIG. 1—TOP VIEW OF REEL up as the vehicle is drawn in. In this way loose cableis prevented from sliding around the floor, and time issaved in handling the equipment. The reel is a simple drum of the style furnished bywire companies to transport cable. It is fitted with adummy commutator which is turned from dry, hardwood and fastened to the side of the reel. This commu-tator has two full circle segments, placed about 5 , and to these segments the wires from the insideof the drum are connected. On the segments rest twocontroller-like fingers which conduct the current from the source to the reel. The segments on the commuta-tor, acting like collectors on a generator, are in contactin any fixed or moving position of the drum becauseboth the commutator and drum turn on a commonshaft. The reeland commutator arefastened to the shaftwith ordinary pipeflanges, which arepinned to the shaftand held to the reelwith wooden end o
