(under subclass 18) Subject matter wherein one of a group of interconnected elements providing rotary drive between said input and output bodies includes members having intermeshing teeth to transmit rotation from one to the other of said members. [figure] [caption] By turning the handwheel 23 the disk 15 may be adjusted along the drum 14 varying the speed ratio of the shafts 13 and 17 as the disk contacts with the larger or smaller part of the drum, as will be apparent. By moving the disk 15 into registry with the groove 25 in the drum 14 the latter is disengaged from driving relation to the shaft 17. With the disk in this latter position the reversing device may be brought into action. This reversing device comprises a gear 30 fixed on the engine shaft 13 and meshing with a second gear 31 carried on a stub shaft 32 journaled in the bearing element 21 above the shaft 13.
