The way to Establish a Regulator Clock
A regulator clock is a generic term for a wall-mounted, weight-driven clock regulated by a swinging pendulum. Invented in the late 18th century to improve upon the truth of spring-wound clocks, regulators usually have separate mechanisms for the hour and minute hands. Once the design was standardized in Vienna, regulator clocks became the most favored timekeeping apparatus in official locations like train depots and post offices throughout Europe and then America. In clock shops, a Navy had been always used as the time standard to which all other clocks in the store were put. Regulators are put by increasing or decreasing the speed of the pendulum swing.
Synchronize the regulator clock into a known accurate time source like the time displayed on a cellphone or pc. Expand the minute hand just in a clockwise direction to place the clock hands to the time.
Wait 24 hours, then compare the time on the regulator clock to the time exhibited through an accurate time source to ascertain any discrepancy in the clock’s precision.
Stop the swing of the pendulum and hold the pendulum still in 1 hand. Find the knurled pendulum speed adjustment nut to the shaft, just beneath the pendulum weight.
Expand the pendulum adjustment nut clockwise to accelerate the pendulum swing and boost the speed of the clock. Expand the pendulum adjustment nut counter-clockwise to slow the pendulum swing as well as the speed of the clock. Each 360-degree rotation of the nut alters the speed of the clock by 30 seconds each 24-hour period.
Wait another 24 hours, then evaluate the time on the regulator clock to the time exhibited through an exact time source. Make additional alterations to the nut to fine tune the accuracy of the clock. Accuracy to within plus or minus two minutes each week is deemed optimal for the design of a regulator clock and also generally can’t be further improved.
