The pendulum hangs from a flat suspension spring, and swings freely. But the rod or leader of the pendulum passes loosely through a loop in the end of the crutch.
The pendulum passes through the crutch loop, and regulates the back & forth rocking of the pallet; and therefore regulates the speed at which the EW is allowed to turn, by how fast it is swinging. To work properly, the crutch loop must be level that is, at a right angle to the pendulum rod.
A basic pendulum consists of a weighted bob, and a stick, hanging from some suspension point. The pendulum is the whole thing, because when we talk about "the mass (weight) of a pendulum", we're including the mass of the stick. [BASIC PENDULUM] View attachment 183643 The period of a pendulum is the amount of time it takes to swing back and forth: from one side of its arc to the other, and back ...
Have a Schneider cuckoo clock, just bought it used, looks very nice & not too old, having a problem with the pendulum, it keeps stopping & only swings for up to about 3 minutes. I loosened the time chain off its cog & wound it another length of the chain, thought that would help but didn’t seem...
i have a 1935 ibm/itr 17-7 master clock with this pendulum.... i was trying to look up how much it weighed (so i didn't have to take the clock apart) and came upon this original ibm/itr doc that seems to say this is a mercury pendulum. is it?
Remember the clock movement powers the pendulum, the pendulum does not power the clock. The fact that the clock runs with the pendulum off indicates that all the internal moving parts are free to move. If the pendulum swings and there is no tic-toc sounds then the clock isn't running at all - the pendulum, for lack of a better word, is just ...
