On itsfirst test the car obtaining its current through this wheelran at the rate of approximately 60 for twentyminutes, the wheel thus making 6000 The anti-friction principle introduced by the rollersmakes it possible to operate this bearing without lubrica-tion. This is accomplished by separating the rollers whichcarry the load by idler spacing rollers, the latter revolvingin a direction opposite to that of the load rollers betweenwhich they lie. This eliminates all sliding contact and pro-vides a completely free rolling motion for both load and. Illinois TractionEquipped for System—Gasoline Emergency CarSummer Use, Ladder Included Roller-Bearing Trolley Wheel with Roller Casing Removedto Show Idle and Load Rolls sired to move along the road the pivoted ladder is swungto a horizontal position to form a T with the standardas illustrated, and it is then held securely by two sectionsof light strand attached to the car frame. The motor carproper is as light as practicable to permit the men to re-move it from the track to clear regular trains. In winter the car consists essentially of an inclosed body spacing rollers, thus preventing any possibility of heatingand scoring even though no lubricant is used.
