Patent GB-740089-A (GB)
Abstract: 740,089. Date indicators. LANSLEY, H. H. March 1, 1954 [Nov. 27, 1952], No. 30031/62. Class 106 (4). A mechanical date indicator comprises amulti-armedpivoted lever K arranged to rotate a primary gear A by an amount dependent upon the angular displacement of the multiarmed lever, at least one secondary gear C rotated by the primary gear, and a cam F and cam follower K<SP>3</SP> on the secondary gear and lever to determine the stroke of the lever in dependence upon the rotational position of the secondary gear C. In one embodiment, Fig. 2, a date unit comprises a datenumber disc L rigid with a 31- tooth ratchet-wheel H, a pinion A and a cam disc E and the pinion A meshes with a pinion C, rigid with a cam disc F, with gear ratio 12: 13. Each time an operating bar Q is depressed against the action of a spring R, a trip S rocks the three-armed lever K about its pivot X against the action of a spring T and, when released, the length of the return stroke of the arm K is determined by the relative positions of the cams E, F in conjunction with followers K<SP>1</SP>, K<SP>3</SP> formed on two arms of the lever K so that the date unit is advanced 1/ 31  of a revolution by a pawl K<SP>4</SP> except at the end of a 30-day month when it is advanced <SP>2</SP>/ 31  of a revolution. A day name disc N<SP>1</SP> rigid with a 7-tooth ratchet-wheel N is rotated through one tooth irrespective of the length of stroke of the lever K. At the end of each complete revolution of the date unit a trip Y advances a month name disc M<SP>1</SP> through a ratchet-wheel M. At the end of February the bar Q has to be operated two or three times and the day-name dial separately adjusted. Alternatively a further pinion may mesh with the pinion A in the ratio 49: 48 and a suitably shaped cam may co-operate with the lever K to vary the advance of the date unit in accordance with the lengths of the months and incidence of leap years. The lever K may be actuated by a clock-driven cam once in 24 hours. In another embodiment, Fig. 3, a pinion A meshes with three pinions B, C, D with gear ratios 1: 1, 12 : 13, and 48 : 49 respectively and the pinion A is rigid with a ratchet-wheel H and date dial L while the pinions B, C, D are rigid with cams E, F, G respectively, which co-operate with follower arms K<SP>1</SP>, K<SP>3</SP>, K<SP>2</SP> of a lever K which carries a pawl K<SP>4</SP> for advancing the ratchet-wheel H daily. The stroke of the lever K is so controlled that the date dial is advanced <SP>1</SP>/ 31  of a revolution each day of the month from the 1st to 28th and thereafter the movement is varied by the positions of the cams in accordance with the number of days in the month and with the incidence of leap years. The day, date and month may be displayed through apertures in a frame suitable for a picture or advertisement.
