Thwaites & Reed Rolling Ball Clock. c.1950's. Case has a mahogany base with felt top, brass tubular posts and railing with spherical brass finials, a long slanted track on top of the case feeds the 35 silvered spherical steel balls down into a double disk spoked paddle wheel below, the weight of the ball rotates the wheel clockwise which drives the clock movement; when the ball reaches the bottom of the wheel it is dropped down through a brass cylinder and directed into the felt covered reserve area below. 5.75 in. silvered dial has black incised Roman hour numerals, brass disc center, brass signature tag for "Thwaites & Reed, London, England" and has pierced black hands; brass weight driven movement has a platform lever escapement signed "Chs. Gorge, SA. Switzerland". All original and in good condition, movement runs when slight extra power is applied and may just need cleaning, also the hairspring needs adjustment or repair to run properly. Clock is wound by replacing the balls back on top of the track. Dimensions: 10.25 in. high x 8.25 in. wide x 8.25 in. deep.
