DEFINITION

Classification: 476/22

Idler between conoidal gears:

(under subclass 21) Subject matter wherein said first and second elements are in the shape of a cone or the frustum of a cone. [figure] [caption] Reversal of the direction of rotation of the driven shaft 2 by the employment of the reverse wheel 18 is due to the fact that said wheel engages the driven cone 4 upon the same side of its axis as the intermediate wheel 11, but upon the opposite side of the drive cone 3 from that engaged by said wheel 11
