ABSTRACT:
A reset mechanism for a cyclometer register employs teeth formed on an axially resiliently urged shaft to engage abutments formed on cyclometer drums to permit resetting of the cyclometer drums. The teeth are normally maintained out of alignment with the abutments by resilient urging of a spring and are manually displaced into engagement for resetting. Carry pinions on a pinion shaft are urged into mesh with respective gearwheels on the cyclometer drums by a pair of springs. During resetting, the pinion shaft, with its pinions, is displaced outward. When the pinions are displaced outward, one or more teeth on each pinion enter a window disposed adjacent thereto in the frame of the cyclometer register. The windows lock the pinions into a predetermined angular position which enables proper mesh to be made with the gearwheels at the conclusion of the resetting operation when the springs again urge the pinions into meshed engagement.
