Abstract

1368137 Ratchet mechanism ENGLISH NUMBERING MACHINES Ltd 6 Sept 1972 [13 Oct 1971] 47704/71 Heading F2Q [Also in Division G4] A bidirectional rotary indexing mechanism comprises a ratchet wheel 12, two selectively movable pawls 15, 16 each mounted so as to move the ratchet wheel in a respective direction of rotation through part of an indexing step when the pawl makes an operative excursion from a rest position, and a third member 28 mounted so that it is displaced when either pawl makes an operative excursion, and arranged to engage the ratchet wheel to complete the indexing step thereof as the pawl returns to its rest position. The pawls 15, 16 are pivotally mounted on a base 14 by means of pivot pins 17, 18 respectively. Two operating members 22, 23 are also mounted on the base 14 and these carry pins 24, 25 which engage inclined slots 26, 27 in tho pawls 15, 16. The member 28 comprises a return pawl having a tooth 37 which is urged into engagement with teeth on the ratchet wheel 12, by means of a spring 36, in order to complete an indexing step after the member 28 has been moved out of engagement with the teeth of the ratchet wheel 12 by the engagement of a lug 34 or 35 on operating member 22 or 23.
