摘要： A counter has a thin, flexible barrier member separating pivotally mounted operating members in the counter so as to accommodate burrs or other imperfections as well as misalignment. The pivotally mounted members are supported on shafts which extend through the barrier member and are biased against the flexible barrier member so that any burrs or roughness on the faces of the moving members abutting the flexible barrier member will produce deflection thereof and movement of the members against the biasing means without interfering with the operation of the counter.
摘要翻译：计数器具有薄的，柔性的阻挡构件，其将可枢转地安装的操作构件分离在计数器中，以便容纳毛刺或其他缺陷以及未对准。枢转安装的构件支撑在延伸穿过阻挡构件的轴上并被偏压抵靠柔性阻挡构件，使得移动构件的面上的任何毛刺或粗糙度抵靠柔性阻挡构件将产生其偏转和构件抵抗该偏置装置不会干扰计数器的操作。

摘要： A counter has a novel drive assembly including a pinion cooperating both with a number wheel and also with an oscillatable ratchet to permit selective adding and subtracting. The pinion member has two adjacent axial portions with each portion having teeth spaced about the circumference. The number wheel is in meshing engagement with a first portion of the pinion member and the ratchet is mounted for oscillation adjacent the second portion thereof. Biasing means is provided to urge a tooth of the pinion member into engagement with suitable means on the ratchet when the ratchet is in either of two positions spaced from a neutral point therebetween, so that return of the ratchet to its neutral point from one of those positions causes rotation of the pinion in a direction opposite to the direction of oscillation of the ratchet. The biasing means also prevents engagement of a tooth with the ratchet at a wrong point during the cycle to avoid spurious action.

摘要： A counter has a novel driving assembly including a pinion cooperating with both a number wheel and an oscillatable ratchet having a pair of pivotally mounted pawls thereon to permit selective adding and subtracting. The pinion member has two adjacent axial portions with each portion having teeth spaced about the circumference thereof. The number wheel is in meshing engagement with a first portion of the pinion and the ratchet is mounted for oscillation adjacent to the number wheel with the pawls engaging the pinion during movement thereof to urge the pinion into driving engagement with another portion of the ratchet. Biasing means is provided to prevent counterrotation of the pinion during return travel of the ratchet.
