Abstract
11,034. Elsdon, C. H. May 14. Calendars; calculating-apparatus.-Three discs 1, 2, 3 turn on a common centre. The disc 2 is marked on the edge with the days of the week repeated five times, and the disc 1 with the months properly spaced so as to show the first day of each month throughout a year when correctly set for any month. At the back of the disc 1 are marked columns of centuries beneath which are slots showing the individual parts of the centuries placed in columns at the back of the disc 2. By means of this arrangement the discs 1 and 2 are adjusted for any year. On the disc 3 is a monthly calendar as shown, which can be adjusted for any month by bringing the number 1 below that month and its first day of the week shown on the other discs. Letters and numbers in dotted lines provide for leap-years.
