Alexander Cumming - longcase clock

A Unique and Interesting antique clock of fine construction.   This George II Mahogany and burr elm domestic longcase regulator by Alexander Cumming is a real triumph of ingenuity. The mechanism with five pillars and rack striking upon the hour is controlled by a deadbeat escapement and regulated by a wooden rod compensation pendulum with heavy brass faced bob.  Other features include bolt-and-shutter maintaining power and a six wheel going train which allows the minute wheel to be geared directly through the going train which achieves less interference to the escapement throughout the strike preparation phase.  In Cummings book "The elements of clock and watch work" he states that "All Clocks may be reduced to two classes; namely, ordinary and accurate . In ordinary Clocks, such as are generally used for domestic purposes, particular regard should be had to their simplicity and expense. In Clocks that are intended for astronomical and other very accurate Observations, no expense should be spared, while the performance can be further improved."  

In this instance he appears to have attempted to achieve both an excellent timekeeper with a domestic function.

Cumming was said to have made this particular clock for the 3rd Duke of Argyle, Archibald Campbell and was commissioned to do so whilst he Installed an organ at Inverary castle.  Cummings later moved to London and quickly established himself with a respected reputation in the city,  so much so that he became an adjudicator for the board of longitude.  Amongst his numerous achievements, Cummings invented the first barometric clock, or barograph, one of which is part of the royal collection and on display in the throne room at Buckingham Palace.

Alex Cummings was one of the founding members of the Royal society of Edinburgh.
