Equation Longcase Clock, by De Rabours

An image of Equation Longcase Clock. De Rabours, France, Paris, Colmar. Equation longcase clock with 8 day hour striking movement and perpetual calendar which takes account of leap year. Louis XV style case.
Dial: Elaborately shaped dial plate 11 1/2 inches wide and 17 inches high, with applied English style chapter ring and seconds ring. The dial plate gilt, the chapter ring and all subsidiary dials silvered. Signed on lower edge of chapter ring ‘De Rabours A Paris' and at base of dial plate ‘Perfectione par Meunier horloger Paris an.1782'. The lower third of the dial is occupied by a semi-circular day of the month indicator with fly back hand, and within the date ring is a simple lunar dial with a scale of days 1 - 29 1/2 and a rotating disc with two moons to point to the age alternately and show the phases. Below the chapter ring at VII are openings to show the times of sunrise and the sun's position in the zodiac. Similar openings below V show the times of sunset and an annual calendar. A slot inside the chapter ring above VI shows the year in the leap year cycle. The day of the week is shown in a slot in the chapter ring near X.
The calendar is set by means of a small squared arbor in an aperture in the chapter ring between VIII and IX, with an adjacent opening so that the calendar can be set to change over at midnight. A lever in a slot outside the chapter ring at X is used to set the maintain¬ing power. Mean time is indicated by pierced and carved gilt brass minute and hour hands, and solar time is shown by a blued steel minute hand. The brass seconds hand is a replacement of 19th century English type.
Movement: 8 day hour striking movement with equation of time and perpetual calendar which takes account of leap year. The going train is weight driven with an anchor escapement and bolt type main¬taining power without shutters. The striking train is spring driven with a going barrel and strikes on the solar hours, which is usual on French equation clocks. The bell
