Anyform of belt may be used, but should not be more than 180 RULES FOR MOVEMENT OF TRAINS 5 wide, and in thickness no lighter than the equivalentof four-ply rubber. One belt of proper dimensions withsuitable fastenings is provided with each generator. The alignment of the belt can be adjusted by loosen-ing the guide and clamps on the cross bar and shiftingthe two outboard arms of the generator to one side orthe other and then d^A^^i. FIG. 80. SIDE VIEW OF GENERATOR SHOWING LOWER FRAME SWUNG DOWN, EXPOSING INTERNAL PARTS, ARMATURE REMAINING IN UPPER FRAME. Advantages of Bliss Suspension.—The advantagesof this form of suspension over all others are: 1. The generator being supported entirely by the up-per portion, the lower portion is left free and clear forinspection and repairs; the lower half of the field frame,armature, bearings, pulleys and all other parts can beremoved without disturbing the supporting framework, HEATING AND LIGHTING CARS 181 2. The adjustment of the belt tension is effected bymeans of a direct longitudinal movement of the genera-tor, which is the universal practice with all stationary beltdriven generators and motors, the roller bearings practi-cally eliminating all sliding friction. The generator notbeing pivoted is not tipped or otherwise drawn out of itsproper position in making wide adjustments of the belttension. 3. The enti
