Murday took out his patent for his Electrically Driven Balance Wheel Clock in 1910 and it was the best known and most successful application of the Hipp Toggle principle to the balance wheel control of clocks. The propulsion system was utilised from his earlier pendulum clocks with modifications for the balance wheel. The balance wheel swings about twenty times before the toggle is acted on and each minute it oscillates fifteen times. Only about 300 were apparently made of which the glass dial versions are the the most scarce. This limited survival and their fascinating aesthetic appearance have made them particularly well known in the field of electrical horology.
