Abstract

169,231. Clark, W. M. June 16, 1920. Calendars and date indicators.-A perpetual monthly calendar comprises a board or tablet A upon which the stationary and movable parts are mounted. The days of the month are arranged in columns E and the day-names of the week, repeated once, are marked on a vertically adjustable endless band D. The first four columns E are permanently marked on the surface but the fifth column is of a length equal to three day-number spaces and is provided with an endless band to display one, two, or three last days of the month or three blanks. A horizontally movable strip C bears the names of the months and the year number, of which the last two figures are carried by endless bands so as to be adjustable, is exhibited at B. An adjustable indicator F is provided to mark the actual day of the week or a particular date.
