In East Windsor, Conn., Daniel Burnap carried on the manufacture of brass clocks. William Tenny was one of the earliest makers of brass work clocks in the United States, and worked at Nine Corners, Dutchess Co., N. Y. Eli Terry made wooden works for his clocks, although he had been instructed in his business by Daniel Burnap, who used brass as well as wooden works, and made tall-case clocks with long pendulums. These clocks were by no means cheap, ranging from $18 to $48, the more expensive ones having a brass dial, a dial for seconds, the moon's phases, and a better case. Terry's wooden-work clocks were well made and were good time keepers, and were distributed all over New England by peddlers. In 1807 Terry undertook to make five hundred clocks; this overstocked the market, and he was forced to reduce the price from $25 to $15, and then to $10. Before 1800 the best-known clockmakers in the United States were Daniel Burnap, Silas Merriam, Thomas Harland, Timothy Peck, and James Harrison, all of Connecticut. From 1806 to 1815 the number of clockmakers largely increased, and Seth Thomas, Silas Hoadley, Herman Clark, and Asa Hopkins were some of the best-known men engaged in the making. In 1814 Terry invented what was called the "short-shelf clock," in which, by a change of arrangement and smaller weights, the pendulum being brought forward and greatly shortened and the weights being carried and run on each side, the whole was reduced to a more compact form. Clock and case were sold for a moderate sum. These clocks, like the tall-case ones, were made with wooden wheels, but after the introduction of rolled brass, machinery was invented by which blank wheels could be struck out with a die, the teeth afterward cut by machinery, and the brass-wheel clocks made cheaper than the wooden. This was about 1837. The next improvement was substituting springs for weights. This had been done in Europe for two hundred years, but only with the most costly parlour clocks, and the springs were equal to the best watch-springs. Many kinds of cheaper springs had been tried without success, till a superior steel spring was invented in the United States, and the springs thus produced have for many years been sold at a price compatible with cheap clocks. The wooden pendulum covered with gold leaf, which is one of the characteristics of a regulator clock, was invented by Silas B. Terry, a son of Eli. America has long taken a leading place in the making of clocks, and that desire to have the biggest and best which is characteristic of the youngest nation has influenced clockmaking.
