Claims14
Apparatus for imprinting time clock data on sheet means, comprising
- (a) first means providing time data in indicia form for presentation toward the sheet means, said first means including wheels carrying the indicia, and shaft structure supporting the wheels,
- (b) control means operatively connected with said first means to automatically and periodically change the indicia presented toward the sheet means,
- (c) and imprinting structure including a roller mounted for progressive advancement at selected times over the sheet means to urge the sheet means toward the time data indicia which are presented toward the sheet at the selected times,
- (d) there being a base plate defining a first through opening, a platen to receive the sheet means, said platen having means for presenting further imprint indicia toward the sheet means, the platen overlying the base plate, the platen defining a second through opening, the platen yieldably connected to the base plate, for movement relative to the base plate in response to roller pressure exertion on said further imprint indicia via the sheet means,
- (e) there being means yieldably connecting the shaft structure and wheels to the platen to move with the platen and further to move relative to the platen in response to roller pressure exertion onto the wheels via the sheet means, said wheels projecting in said second through opening to present the indicia to the sheet means, said connecting means positioned in said first through opening.
