Gravity mantel clock, made in France and retailed by Barraud & Lund, London, circa 1880.

Physical Description

Round clock under curved wooden canopy supported by four tapering pillars. Two vertical brass runners, one with regular teeth. The toothed runner meshes with the gear mechanism of the clock and the weight of gravity causes the clock to descend the brass runners, thereby operating the mechanism. The weight of the clock is constant so at any one place the motive force is constant.
