ABSTRACT:
A counting device of the kind having coaxial number wheels each with a reset cam and transfer pinions mounted on a shaft which is displaceable relatively to the number wheels the pinions being located between successive number wheels with each pinion meshing with gear teeth on an adjacent number wheel and adapted to engage drive means on the other adjacent number wheel so as partially to rotate the number wheel with which it is in mesh. Reset fingers are provided which are together rotatable about a common axis respectively to engage with the reset cams to reset the number wheels, the reset fingers and transfer pinions being located, prior to resetting, respectively out of engagement with the reset cams and in engagement with the gear teeth on the number wheels. A reciprocably movable actuating member is also provided to effect resetting of the number wheels during movement in one sense and upon movement in the reverse sense is repositioned for subsequent resetting action. A cam element is provided which is rotatable relatively to the number wheel axis during an initial part of the resetting movement of the actuating member to effect displacement of the transfer pinion shaft to disengage the pinions from the gear teeth on the number wheels, and, abutment means are fixed relatively to the reset fingers and adapted during a subsequent part of the resetting movement of the actuating member to reverse the rotation of the cam element so that after resetting of the number wheels and while the reset fingers are engaged with the reset cams, return movement of the transfer pinions with the gear teeth on the number wheels is effected.
