IDENTIFIERS ----------- id: 95862 accession number: M.22-1947 DATE AUDIT ---------- created: Saturday 6 August 2011 updated: Friday 6 October 2023 DESCRIPTIVE DATA ---------------- object type: Dial: Dial plate 12 inches by 16 7/8 inches high, with spandrels and chapter ring within an engraved line 11 1/4 inches square. Silvered chapter ring engraved I-XII twice and 5-60 twice with minute and half minute divisions outside the minute numbers and half hour divisions on the inner edge. The chapter ring engraved near the top with ‘EQUAL TIME' and with fleur de lys type half hour marks. It is mounted on the matted dial centre which is supported on three dial feet independently of the dial plate. Surrounding the chapter ring is a rotating minute ring with divisions and numbers as on the chapter ring and inscribed at the top ‘APPARET TIME'. The spandrels are of a cherub and flower design (Cescinsky & Webster, No.7) introduced by Tompion and used mainly by him. Between the spandrels fine scrolling foliage is engraved and at the lower edge ‘THO. TOMPION.LONDON.INVENT.' Curved openings below the dial centre show the days of the week, each with its appropriate deity. Similar openings above the chapter ring display an annual calendar and the sun's position in the zodiac. Finely pierced steel hands, the minute hand being accurately balanced and having a gilt tip to point to apparent time. Movement: The year timepiece movement has no seat board but rests directly on metal plates on the tops of the reinforced sides of the case. The movement is inverted, with the escapement at the bottom, and is made in two sections with the barrel assembly and the second wheel in a small frame to the rear. The remainder of the train and all the calendar and equation work are mounted on the large front plate. Bolt and shutter maintaining power is fitted to protect the delicate escapement and is operated by a lever on the right hand side of the dial. The equation cam, on the same arbor as the annual calendar, is driven by a vertical arbor from the motion work. A bell crank which follows the cam carries a rack which engages with a wheel at the centre of the apparent time ring and moves it backwards or forwards as required. Case: Has an oak carcase veneered with burr walnut and with narrow herring-bone bandings. The skirting appears to be original. The case has a rising hood, originally without a door and with acanthus design side frets of walnut veneer. The very elaborate superstructure appears to be of slightly different carcase wood and to be slightly later in date than the rest of the hood. A disturbing feature of the case is that, with the hood door closed, both calendar and zodiac slots are covered and when the door is opened only the calendar slot is visible. Arising from a consideration of these peculiarities it is suggested that the hood, originally without a door, had only a modest-sized superstructure. Traces remain of the spoon lock for securing the hood and the catch for holding it in the raised position. The hood would have had to be raised for winding or adjusting the clock when both calendar and zodiac slots would have been visible. It is quite probable that the original customer wanted a more imposing clock in keeping with a lofty room and the large caddy top with its elaborate mounts was then provided. The hood thus became too unwieldy to raise for winding or setting the clock so a door was made. The trunk door has its original iron lock and hinges, exceptionally three in number. The remain¬ing mounts are of gilt brass and include fine vase and urn finials, a central figure of a warrior, probably Mars, and fine repoussé frieze frets consisting of strapwork and of floral scrolls wtih central female mask and cherub heads at the corners. Like other special clocks the trunk door has tiny metal spandrels in the corners. The `gothic' shaped metal frame to the pendulum window is also used on the William III clock mentioned belowand resembles a design by David Marot. object type: Oak case with burr walnut veneer, pierced and cast ormolu mounts, including urns and a Roman warrior. Below the dial is an opening showing the days of the week with their deities. Above the chapter ring openings display an annual calendar and the sun's position in the ecliptic, its apparent annual path through the heavens. The movement is of year duration. title: Year Equation Timepiece NOTES ----- type: history note value: Said to have been supplied by Tompion to Drayton House, home of Lady Mary Mordaunt, Duchess of Norfolk after her separation from the Duke in 1692.
