Abstract

1,099,459. Date and time printing apparatus. S. C. CAUSER. Dec. 22, 1964 [Dec. 23, 1963], No. 50722/63. Heading B6D. [Also in Divisions F2 and G3] Mechanism for the display or printing of the time of day and of the day or date comprises three rotary discs 21, 32, 45 which are advanced quickly at intervals of 1 minute, 1 hour and 1 day respectively, and remain stationary between the movements of advance. An input shaft 11 is driven at 1 r.p.m. The shaft carries a worm 13 having a cam 15 of the same helix angle as the worm and spring-urged toward a fixed cam 16. Worm-wheel 19 in mesh with the worm 13 advances the minutes disc 21 on shaft 20. The worm 13 performs an idling stroke against spring 17 owing to cam 15; once each revolution the cam releases the worm which moves longitudinally to advance the wormwheel. Worm 13 also meshes with a worm-wheel 22 on shaft 23 which carries a second sliding 24 having a cam 27 and functioning similarly to advance the hours disc 32 through worm-wheel 30 on sleeve 31. This sleeve carries a bevel gear 33 meshing with bevel gear 34 on shaft 35 which carries a spur gear 36 meshing with spur gear 37 on shaft 38. This shaft carries a third sliding worm 39 with cam 40 which as before advances a day disc 45 through worm-wheel 43 on sleeve 44. Worm 39 also drives a worm-wheel 46 on a shaft 47 which constitutes an output for driving ancillary equipment.
