Rod 1 reciprocates in fixed guide p and is connected by turning pair C to bellcrank 8. Lever 3 turns about fixed axis A and is connected by turning pair B to link 8. Links 8 and 3 are connected by turning pairs D and E to links 5 and 9 which are connected together by turning pair F. Link 5 is designed as a pawl which engages ratchet wheel 2. Pawls 10, 6 and 7 turn freely about axes D, E and G of links 5 and 3. Pawls 5, 6 and 7 are held by springs, secured to link 8, against ratchet wheel 2. When rod 1 reciprocates, pawls 5 and 6 turn ratchet wheel 2 intermittently clockwise about axis B. Pawls 7 and 10 prevent rotation of the ratchet wheel during the return stroke of rod 1.
