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. Flexible members are provided which are disposed to be out of contact with the transfer pinions during counting operations of the device and located so as to be engaged respectively by the transfer pinions during reset operation of the actuating member thereby to reorientate the pinions and abutment means which engage and stress the flexible members after engagement thereof with the transfer pinions so that contact between the pinions and the flexible members is maintained until remeshing of the pinions with the number wheel gear teeth takes place, the flexible members thereafter disengaging from the pinions.
