Edward Barlow

from Wikipedia, the free encyclopedia

Edward Barlow (* 1636 ; † 1716 ; also Edward Booth ) was an English watchmaker .

Life

Barlow is considered the inventor of the hammer mechanism for clocks, which was documented by his patent application in 1686. The invention of the hammer mechanism made it possible to check the time even in the dark. The watch indicates the current hour and quarter of an hour acoustically via an acoustic signal every time the lever on the watch is pressed. Daniel Quare appealed to the King against Barlow's patent application. Quare stated that he had developed the hammer mechanism as early as 1680. Barlow's patent application was denied, but today both Barlow and Quare are considered the inventors.

In addition, Edward Barlow received a patent for a forerunner of the cylinder escapement in 1695 together with Thomas Tompion and William Houghton . His invention had a decisive influence on the development of pocket watches with hairspring and balance .
