Glossary of Terms
Automatic beat adjustment (a Kieninger patent): Ensures a perfectly even tic sound will develop after the over swing period of the pendulum is completed.
Automatic night shut-off (a Kieninger patent): When activated, is automatically shut-off the chimes or strike between:
• 10.00 P.M. and 7.15 A.M. (movements with quarter hour chime);
• 10.00 P.M. and 7.00 A.M. (movements with half hour strike).
Case: The timber frame of the clock that houses the clock's moving parts. In Clocks & Chimes timepieces, is constructed from solid hardwoods, and in some cases, has decorative inlay.
Compensation pendulum: Compensates for the different expansion rates of the metallic components in the pendulum, which otherwise would affect the length of the pendulum and consequently the running speed / timekeeping.
Dial: the face of the clock, white enamelled with either Roman or Arabic numbers.
Mechanism: the mechanics that turn the hands to give time and produce the chimes and strike (gong).
Movement: - the driving and regulating parts of a mechanism.
Key Wound: The clock is wound up by inserting the supplied key into the holes in the dial and turning.
Pendulum: Shaft and pendulum bob, normally brass, with a thread and nut at the bottom to adjust timing of clock. The longer the pendulum, the slower the clock runs.
Weights: These are lead and cased in brass shells. When facing the clock, these have the following functions from left to right:
• Kieninger®-PS055 / PS55 movement - is a front wound cable movement with 1/2-hour chime on a coiled gong, automatic beat adjustment, automatic night time shut-off between 10.00 PM and 7.00 AM as well as complete chime shut-off facility.
It has two seperate weights: the left drives the hour strike mechanism, and the right drives the time drive.
•
Kieninger®-RSW movement - is a 1/4 hour cable/key front winding movement with Westminster chime on 8-rod gong, automatic beat adjustment, automatic night time shut-off between 10.00 PM and 7.15 AM and complete chime shut-off facility.
It has
two weights on a single yoke, which drive the time drive. Both the strike set up and the melody set up are spring driven.
