This clock has clear synthetic ruby pallets. (Dial on the right side.) The Riefler escapement is a mechanical escapement for precision pendulum clocks invented and patented [1] by German instrument maker Sigmund Riefler in 1889. [2] It was used in the astronomical regulator clocks made by his German firm Clemens Riefler from 1890 to 1965, [3 ...
Elias Ingraham (1805–1885) opened his own shop in Bristol in 1831 as a cabinetmaker and designer of clock cases. [1] While on a voyage to Caracas, Venezuela in the 1840s, Elias designed the four-column Sharp Gothic steeple clock, which was widely copied by other clock makers and sold so extensively around the world that it is believed to have been the best-seller of any distinctively ...

Grasshopper escapement, 1820. The grasshopper escapement is a low-friction escapement for pendulum clocks invented by British clockmaker John Harrison around 1722. An escapement, part of every mechanical clock, is the mechanism that gives the clock's pendulum periodic pushes to keep it swinging, and each swing releases the clock's gears to move forward by a fixed amount, thus moving the hands ...
