BRACKET CLOCK John Bushman London Ca. 1730 England
Signed: John Bushman London
The spring-driven double fusee movement is constructed between brass plates and consists of going and striking trains. The going train has verge escapement with a short pendulum, whilst the rack striking indicates the hours fully on a bell. In addition the movement has pull quarter repeat on demand with six hammers on six bells. After the quarters have been sounded, the hour strike follows on the larger bell. The backplate is profusely engraved depicting leaf and scroll motifs around a signature cartouche, which has the maker’s name: John Bushman London.
The arched brass dial has a silvered Roman chapter ring with half-hour, Arabic five-minute and minute divisions. There is a date aperture above the VI in the matted centre. The time is indicated by a fine pair of pierced blued steel hands. There is a silvered brass ring in the arched with a blued steel hand-shaped lever to regulate the movement, so-called rise-and-fall regulation. Below the middle is a silvered brass plaque with the engraved signature of the maker: John Bushman London. The four corners are embellished by crown-and-head spandrels.
The ebonised pearwood veneered oak case has a so-called inverted bell top and glazed doors to the front and back, so that the movement is visible. The top corners have pierced corner pieces which function as sound windows. The case is surmounted by a brass carrying handle and rests on four ebonised pearwood feet.
