Description
This is an example of an Ithaca Calendar Clock model called “3 ½ Parlor” from the mid 1870s. Its walnut case has ebonized decorative elements. The black upper dial shows the time in white Roman numerals, with winding arbors at IIII and VIII for the brass eight-day time-and-strike spring-driven movement behind the dial. Lower clear glass has reverse-painted white Arabic numerals for date of the month. Metal calendar apparatus visible inside case, where rotating wheels show weekday and month.
The Ithaca Calendar Clock Co., established in Ithaca, N.Y., about 1865, made clocks based on the automatic perpetual calendar mechanism patented by Henry Bishop Horton in 1865 and 1866 (see patent 57,510).
