Brass Congreve Rolling Ball Mantle Clock. Case has brass plates supported by turned brass posts with pineapple finials on the corners and brass feet which are threaded for balancing the clock and large center finial at the top; silvered 4 in. chapter ring has black incised Roman hour numerals and blued hands. Double barrel & cable spring driven movement is engaged by a brass plate with a 15 row track on which a steel ball rolls down, when the ball reaches the end it triggers a lever which reverses the incline of the plate redirecting the ball back down the track; the track plate is set on a knife point edge at the top of a post centered on the bottom plate. Each row of the track registers one second which changes the incline of the track every 15 seconds or 4 times per minute. Silvered tag on the front pays tribute to the inventor Sir William Congreve, London; stands on a white marble slab with turned brass feet and under a glass dome with brass framework. In good working condition, hands are replaced, center finial is repaired, circa 20th century. 19 in. high x 16 in. wide x 10 in. deep.
