Hands and ratio gearing are back on after straightening the bent shaft.
Seems to be doing fine.
The view from the left side between the plates shows a large chrome cylinder or barrel that houses the mainspring. Above it is the more conical shaped cable drum that, together, comprise the “fusee” powertrain. The fusee was invented long ago to provide more consistent power from the mainspring throughout the winding cycle. Mainsprings tend to impart more power when they are fully wound, then lose power as they unwind. The fusee compensates for this. More consistent power results in more accurate timekeeping.
The small “office” clock over the control switch allows the tower clock to be set without having to actually have the tower clock in the line of sight. What is shown on the office clock is what the tower clock will display (assuming I did it right!)
This certainly isn’t the tallest or most challenging tower clock I’ve repaired, but it’s another one under my belt. This one is in Mesa, AZ, in an old shopping center that is undergoing renovation. The center was originally built in the 60’s.
First pic shows a badly worn clock weight pulley strap. Next are the bushings I made for the repair. The last pic shows partial assembly. I’m really having fun making use of my newly acquired machining equipment.
My Very First Tower Clock. Here’s a photo I dug up that was taken back in 1978. At the time, I was the service manager for Ted’s Clock Emporium in Glendale, California. (you can read more about that on my “About” page on my website). The local newspaper must have been having slow news day so they came and did a human interest piece on Ted’s. Yes, that’s me standing precariously on the rails. You can’t see it in the picture, but under my smock is a safety harness.
The story behind this clock is that the movement was originally from a bank building that was destroyed in the 1906 San Francisco earthquake. The Mall developer had a new “tower” built for it near the food court. It had been motorized for automatic winding and not long afterwards, it started giving them trouble. Ted’s had a store located in the mall so we were the ones management called to repair it. This was truly “learning on the job” for me.
I chuckle every time I read the caption under the picture, “All repair work is done on Ted’s premises”. Clearly this one wouldn’t have fit on my bench!!
