What is the crutch on a pendulum clock

Re-set the time by moving ONLY THE MINUTE HAND counterclockwise (backwards) as described in Step 5 of the set-up operation. EXAMPLE: Clock chimes at 1:10 but should chime at 1:15. Step 1: When clock chimes at 1:10 stop the pendulum and record the time of 1:10. Step 2: Carefully remove the small nut.

The crutch is the thin brass rod that connects the escapement to the pendulum. It extends from the upper part of the clock movement down along the pendulum suspension rod and loops. Pendulum top and bearing assembly from the other side. The cylindrical, black-painted counterweight of the gathering pawl and the pawl bearing can be seen centre right. The black bar hanging almost against the main frame is the.

The 10 foot long pendulum beats approximately two seconds allowing the escape wheel to turn once every 2 minutes. The bob is about 14 inches in diameter 30 lb. weight. The anchor and pendulum crutch have been modified. Winding takes place through a metal loop in the pendulum rod. Striking train. All the original wheels have been retained.




The crutch provides power to the clock’s pendulum to keep it swinging So Sivaramann started learn how the crutches and beat-setting screw mechanisms worked in the world’s best clocks. And armed with more knowledge, he then realized that his old clock was far from being a perfect – or even a good – timepiece.

A full turn will make the difference of two minutes in a 24-hour period. If the key is missing, the pace can also be adjusted from the back by raising and lowering the pendulum’s ball. To set the correct strike, start the minute hand at the 12 o’clock position before moving it to either the 9 o’clock position or the 6 o’clock position.

an important part of oiling your clock. The pendulum is made up of a “pendulum bob” a pendulum body (this body could be made of wood or metal) and the pendulum hanger at the top. The pendulum hanger will hang on a piece called the pendulum leader. The pendulum leader is attached to the clockscrutch”. (see figure 11).
