Abstract
THE pioneer of the electric clock was Alexander Bain, whose patent was taken out in 1840. He was soon followed by others, and in 1851 C. Shepherd installed in the Great Exhibition a large electric clock having one great dial in the transept and two others at the ends of the building. Speaking of this and other clocks, Timbs said: “the application of electricity to the measurement of time for the purposes of the Great Exhibition was an appropriation in every way accordant with the spirit of the grand scheme “of enlightenment as well as with the genius and skill evinced in the Great Building itself.” Shepherd's clock attracted a good deal of attention and since then electric clocks have been extensively used in warehouses, factories, railway stations, offices and ships, and many types have been evolved, with all of which Mr. Philpott deals.
