Abstract

5039. Dreyfus, G. March 1. Calendars.-The object is to reduce the number of superposed interchangeable cards as much as possible. The Figures show one form, which may, be variously modified. The days of the week are printed at the top and bottom edges (on both sides) of two cards A ; the days of the month on all the edges of four square cards B ; the names of the months on top and bottom edges of three cards C. In addition, four cards D may be employed giving the various possible arrangements of the days of the month with respect to the weekdays.
