Rotation is transmitted from c rank 1 to driven shaft 2 by means of roller 3 which presses slanted washer 4 to fixed, cone 5, imparting a complex spatial motion to the washer. Washer 4 has slotted member a whose slot slides along block 6 which is pivoted to pin c. Pin c is mounted in clevis 7 which can be adjusted along feather key b of shaft 2 to change the height position of block 6 and, thereby, the speed of shaft 2.
