. Electric locomotive haulage in and about mines . PLATS 31. 21 operating the locomotive. mhe spring reel has a further advantage in as much as it may be removed from one locomotive and transfer- ed to another locomotive as conditions in the mine demand; or if a gathering machine- is not needed in the development of a new part of the mine, the reel may be used in some other part of the mine, or it may be stored away, thus keeping it in better working order. Both the Jeffrey Go. and the Baldwin TTestinghouse Go. as make use of much the same types of reelsAin the locomotives de-scribed above. Regarding the superiority of the electrically driven reelover the spring and the mechanical types, I would say that theelectric drive is most desirable, in as much as it is a self con-tained unit; the motor when acting as a generator sets up a torquewhich causes the cable to pay out more evenly than the other typesof reels do; low voltage and mining conditions affect the reelvery little; and it requires very little power to operate it.
