Kind Code:
B2
Abstract:
A reset device for resetting the digit drums of a counter wherein the drums are coupled by transfer pinions mounted on a shaft which is movable to disengage the transfer pinions from the digit drums during the resetting of the digit drums by reset fingers acting on heart-shaped cams associated with the digit drums, the reset device including a resilient element which is movable with the reset fingers, is engageable with the shaft and defines two stop positions of the shaft relative thereto, the positions being such that on operation of the device the shaft in one stop position is initially moved with the resilient element to disengage the transfer pinions from the digit drums, on further movement of the resilient element during which the reset fingers act on the cams to reset the digit drums, the shaft abuts a stop and the resilient element moves relative thereto to move the shaft into the other stop position, and during the reverse movement of the resilient element the shaft in the other stop position is moved back to reengage the transfer pinions with the digit drums and is thereafter moved relative to the resilient element back into the one stop position thereof.
