CALCULATING MECHANISM FOR TEN KEYS - FOUR SPECIES - CALCULATING MACHINES

摘要

The specification discloses a calculating mechanism for transferring values from a value detecting rack to a counter gear in which a setting disc has teeth meshing with the rack and a peripheral cam with a sharp rise at one end. A control wheel which rotates on each machine cycle has a toothed sector pivotally mounted thereon and biased away from engagement with the counter gear. The sector has a cam on the inner side in the plane of the cam on the setting disc with a sharp rise at the leading end. The cams move the sector into engagement with the counter gear when the rises meet so the adjusted position of the disc determines the amount of rotation imparted to the counter gear when the control wheel makes a rotation.
