Pin wheel 1 rotates about fixed axis A and carries pin a which consecutively engages straight radial slots b of Geneva wheel 2. Geneva wheel 2 rotates about axis D of arm 5 and its five slots b are symmetrically located. Geneva wheel 2 turns 1/5 revolution to each revolution of pin wheel 1. Geneva wheel 2 is rigidly attached to gear 3 which meshes with gear 4 and transmits intermittent rotation to it about fixed axis C. Gear 3 also meshes with gear 6 which rotates about axis B of arm 5. Gear 4 can be reversed by turning arm 5 about axis A so that gear 3 is taken out of engagement with gear 4 and gear 6 is brought into engagement with gear 4.
