Frank Hope-Jones, 1868-1950 was, the co-founder of the Synchronome Company in 1897 and his contribution to electrical horology was only second in importance to that of Alexander Bain. His Synchronome Company was a great success supplying clocks to shops, Government and public buildings and railway stations both in the UK and abroad.
The patent for Hope-Jones's free pendulum clock was granted on March 22, 1937 and his 1935 Christmas card (see illus.) was designed to be a puzzle which he followed with by an article printed in The Engineering Gazette, February, 1936 giving a full and typically individual explanation. In it he tackles the interesting question of how the 'free' pendulum can remain 'free' even when being given work to do. The present example is one of only two known examples, the other being in the Science Museum (cat. no. 1985-475). That particular example is also lacking its pendulums and weight and has a manual winding system as opposed to the motor-wound system found on the present example
