Abstract
137,913. Robinson, R. W. Jan. 24, 1919. Calendars.-A perpetual calendar comprises a chart a of tables showing year letters and month numbers for 24 centuries under both Julian and Gregorian styles, and an adjustable slide b marked with a month's dates (repeated where necessary). This slide is set with reference to the day names p by means of a scale and finger-piece b<1> according to the month's number as given by the chart; any unnecessary terminal dates (29, 30, 31) are covered by a shutter movable in the thickness of the slide b by means of a setting- piece c<1>. The name of the month is borne by a rotatable disk f, and the number of the year is shown by disks g, h. A lettered disk i exhibits the year letter. Instructions for setting the calendar are printed in the space k. In a modincation, the chart is printed on the back of the calendar, and the various slides are set from the back.
