Plate cam 1 rotates about fixed axis A and is rigidly attached to gear 4 which meshes with gear 5. Cam 2 is rigidly attached to gear 5 which rotates about fixed axis B. Gear 5 has twice as many teeth as gear 4. Follower 3 reciprocates in fixed guides C-C and carries two rollers, 6 and 7, which roll along the contours of cams 1 and 2. Cams 1 and 2 alternately actuate rollers 6 and 7, transmitting complex periodically varying motion to follower 3. Roll 5 or 7 is held in contact with cam 1 or 2 by spring 8.
