Great Wheel
In the fuzee it is the toothed wheel which transmits the power from the fuzee to the center pinion. In the going barrel the toothed portion corresponds to the great wheel. In clocks without a barrel it is the wheel mounted upon the same arbor as the mainspring.
GRIGNION, THOMAS. A well-known watch and clockmaker, of London, who died in 1784. His son Thomas, also a clockmaker, claimed for him the honor of bringing to perfection the horizontal principle in watches and the dead beat in clocks. GROSSMANN, MORITZ. A celebrated horologist, author and linguist. Though born and raised in Saxony, he was very conversant with the French, Italian and English languages, and contributed to many technical journals throughout the world. He was a member of the British Horological Institute, the Galileo Galilei, Milan, Italy, and the Polytechnic Society of Leipzig. It was while in the hall of the latter society, and just after delivering a lecture on horology, that he was stricken with apoplexy, which resulted in his death Jan. 23, 1885. He received his training as a watchmaker under the best masters of Saxony, Switzerland, France and England. He located in Glashutte, Saxony, in 1854, and began the manufacture of fine watches, tools and metric gauges, and later on large sized models of the various escapements. His first essay, "The Detached Lever Escapement," was written in 1864 and was awarded first prize by the British Horological Institute. In 1869 he took the first prize offered by the Chambre de Commerce, Geneva, on the subject of "The Construction of a Simple and Mechanically Perfect Watch." In 1878 he published a translation of Claudius Saunier's "Modern Horology."
