DETENT MECHANISM FOR MECHANICAL COUNTER HAVING PARTITION MEMBER CHUN-WEI YANG A counter includes a housing, a mask having an opening therein defining a viewing station and units and tens counter wheels coaxially aligned and rotatably mounted on the housing in alignment with the viewing station. Means are provided for operably connecting the counter wheels to drive the tens wheel in accordance with the rotation of the units wheel. A detent wheel is mounted on the hub of the units wheel for movement therewith. A partition member is situated between the counter wheels and spring means mounted on the partition member cooperate with the detent wheel to position the units wheel relative to the viewing station after each rotation thereof. The spring means includes a base member and a pair of leg members one of which extends from each end of the base member to form a "U" shape configuration. The leg members are bent to form a pair of protrusions which are spaced to receive the detent wheel therebetween. A mounting member is connected to the base member and is provided with a pair of mounting arms which are bendable to form a space into which the partition member extends.
