The flexible couplings 48, 41 are introduced in the motor shaft SI to compensate for possible disalinement between the motive and driven element.
The modification in Fig. 6 is the same as the structure and mode of operation described except that the driven shaft "a: is driven by the gear worm 33:: on the counter shaft 34:. This counter shaft is driven by the pulley 43 and the belt 44 engaging the pulley 48 on the shaft of the motor 352:. A plurality of pulleys can be driven as by the second worm 33m. This belt drive has some advantages due to .the flexibility oi the belt 44 in starting and possible slippage with consequent prevention of damage to the motor should the traction unit become jammed by a foreign obstruction entering tthe unit.
Having thus described this invention what is claimed and desired to be secured by Letters Patcntis:
i. In a returnway in the class described, a ball retarder including a substantially cylindrical brush; a traction member within the arc of said brush and means for driving said traction member in a direction opposite to the normal rotation of a ball rolling through said brush from said retumway.
2. In a returnway in the class described; a ball retarder including a substantially cylindrical brush: a pair of parallel traction belts adapted 6 to travel at relatively different speeds; a motor geared to said belts; and a motor switch control for said motor between said belts in the path of a ball passing through said brush.
3. A returnway in the class described, includ- 10 ing a substantially cylindrical brush: a pair of parallel traction belts within the perimeter of said brush; and means for driving said belts at different speeds.
4. A returnway in the class described, includ- 15 ing an inclined ball support: a substantially cylindrlcal brush arranged above said support: a traction means within the perimeter of said brush and forming a continuation of said support: and means for driving said traction means. 20
5. A returnway in the class described. including an inclined ball support: a substantially cylindrical brush arranged above said support a traction means within the perimeter of said brush; and means for driving said traction means in a 25 manner to alter the normal rotation of a ball descending said support as it passes through said brush.
