The best way to check this is with the leader removed. The tick or tock sends a. Re-set the time by moving ONLY THE MINUTE HAND counterclockwise (backwards) as described in Step 5 of the set-up operation. The escapement is driven by force from a coiled spring or a suspended weight, transmitted through the timepiece&39;s gear train. Its better, or worse, depending upon the temperature, as the wooden pendulum stick moves. Finally, the pendulum may gently be lowered, allowing the suspension to pass down through and out of the crutch. 99 3. Adjusting the wire crutch simply requires bending or straightening the elbow, which alternately changes the depth of the engagement or impulse face until the movement is in beat.

Bend the crutch rod while supporting it with the other hand. . When moving an eight-day longcase clock you need to hold the weight lines in place by taping round the accessible part of the barrel. The impulse action transfers energy to the clock&39;s timekeeping element (usually a pendulum or balance wheel) to replace the energy lost to friction during its cycle and keep the timekeeper oscillating. Setting your pendulum clock in beat. The addition of a pendulum to the mechanical clock improved its accuracy and allowed a more precise measurement of time. To adjust a pendulum clocks speed, the key is knowing the right length. 2 Different Styles of Hands The 2 different styles of hands can match diverse colors, patterns, shapes of clock panels, also providing a decorative effect. The pendulum swing time is measured by an optical sensor and a 32 bit counter, counting 10 MHz clock ticks from the Maser. When the case is secured, hang the pendulum, shiny side to the front, checking that the suspension spring lines up with the crutch. This lasts for a short period that ends when another tooth on the gear train strikes the opposite arm of the pendulum, which locks the gear again.
