Abstract: In sliding clasp fastening means comprising longitudinally extending mating strips and a U-shaped sliding clasp providing a channel fitting over the strips, the channel width tapering in the longitudinal direction of the strips and having adjacent the end thereof of greater width a pillar which fits between and holds the strips apart so that reciprocal movements of the clasp cause engagement or disengagement of the strips, the provision on one or both sides of the channel of means adapted to receive a tool operable to effect resilient separation of the sides of the channel to facilitate fitting of the clasp over the strips.

Abstract: A counting device of the kind having coaxial number wheels each with a reset cam and transfer pinions mounted on a shaft which is displaceable relatively to the number wheels the pinions being located between successive number wheels with each pinion meshing with gear teeth on an adjacent number wheel and adapted to engage drive means on the other adjacent number wheel so as partially to rotate the number wheel with which it is in mesh. Reset fingers are provided which are together rotatable about a common axis respectively to engage with the reset cams to reset the number wheels, the reset fingers and transfer pinions being located, prior to resetting, respectively out of engagement with the reset cams and in engagement with the gear teeth on the number wheels. A reciprocably movable actuating member is also provided to effect resetting of the number wheels during movement in one sense and upon movement in the reverse sense is repositioned for subsequent resetting action.
