Clock Repair of an Unusual (for me) Mechanism

Image Captions are Below the Article in Text for Translation Purposes.

A clock, Linden Chime, Wall Clock, Battery Operated, Timed by Pendulum, not a Quartz Movement. I found this clock, being thrown away, brought it home, cleaned it up, bought a pendulum (it was missing), and it’s worked for over a year. Recently it stopped, so I removed the movement, lubricated it with Air Rifle Lubricant I have (not for the Compression Chamber, for other Moving Parts), it’s like water, but it supposedly adheres to the metal, leaving a slick surface. It ran for a few days, then stopped.

Representative Image #2, My Clock’s Face Cover Opens like this, but my Clock is Circular and it is Longer Below the Face. 

I disassembled it further, and noticed it has a movement similar to old Automotive Clock Movements. These movements were actually mechanical, but relied on a mechanism to cock them when a pair of Electrical Contacts came together. It would then run-out the spring tension, operating the clock as if wound, and continue until the contacts closed and cocked it again, repeating this cycle.

My Linden has a Battery Operated Motor for the Chimes, they are physical rods struck by 2 hammers that are Battery Powered in their motion. But no motor for the movement. It seems that when the Chimes are activated, they rotate a drum associated with the clock movement, and the chimes essentially wind the clock. It’s possible that the clock spring was insufficiently wound to run the clock, so I again cleaned and oiled the movement (as best as I could) and ran it through the chime cycles repetitively. This should wind it as the Pendulum was not moving, and the repeated Cycles of Chiming Wind the Movement.

I could buy a Quartz Movement with Decorative Pendulum, but it’s not the same, and I’m a purist.

Clock Style Rear View Alternate Movement

This is a Quartz Replacement Movement, No Chimes, Requires Removing from the Wall to Set (see the little Knob), Decorative Pendulum. Still, it make an Old Clock Case Functional. I have a Mantle Clock that I replaced a Broken Mainspring Wind-Up Movement with a Quartz Movement, there was no Visible Pendulum, so that was not a consideration, but the Movement had Chimes and the Quartz Movement has Speaker Chimes that work well enough for me.

Clock Style Rear View

This is an Apparently intact Hexagonal Clock (mine is round) with the Original Movement, the Movement is Identical in Appearance to mine, but this one uses a Shorter Pendulum and by design has a Shorter Case.  One D-Cell Battery, Chime Bars mounted to the Case, Chime Hammers also seen. The Battery Powers the Chime Motor, and the Chime Motor Operates the Chime and Winds a Spring in the Clock Movement to keep it operating.

Clock Style Rear View Movement Close-Up

Close-up of Hexagonal Clock Movement that is identical in Appearance to the Movement in my Clock. Battery Compartment for One D-Cell, Pendulum Suspension, Chime Hammers and Chime Bar Mounted on Clock Case to the Right in this view. This is not a Quartz Movement, there is no Time Set Knob on the Movement, and the Pendulum is a key part to the Operation and is not Decorative.

Highlights:

➊ Battery Powered Wall Clock with Chimes.

➋ Not a Quartz Movement.

➌ Clock Appears to Wind the Mainspring During Chime Cycles.

➍ Pendulum is Functional (not Decorative), and is used to Set the Clock Faster (by moving Pendulum Bob Up), or Slower (by moving Pendulum Bob Down). Clock can be stopped by Stopping Pendulum. Decorative Pendulums Suspension can often be Parked and the Movement used without the Pendulum.

➎ The Time can be set by Moving the Minute Hand Forward.

“This is the Style of my Clock, Round Face, Long Case, but wait, somthing is amiss. To quote a coworker, this clock is Hung like a Hamster (a Freudian Reference to his Manhood).

This Pendulum is much shorter than mine, and there’s a reason. This Clock has a Quartz Replacement Movement with no Chimes (though the Chime Bars are still there from the original Movement), and the Pendulum is purely Decorative.

My Movement, though Battery Operated, actually relies on the Pendulum to function and the length of the Adjustment of the Pendulum Bob (circle area on the bottom of the Pendulum) will make the Movement Run Faster (Move the Pendulum Bob Up), or Slower (Move the Pendulum Bob Down). If on my Clock I need to set the the Time Back One Hour, I simply Stop the Pendulum for an Hour and then Start it again, and similarly if it’s a little fast, Stop the Pendulum, wait a few minutes, Start it again.

My Movement is Set by Moving the Minute Hand Forward, so the Clock Running a Little Slow is easily corrected by moving the Minute Hand Forward, whereas if it’s Fast, you need to Stop the Pendulum then Restart at the Appropriate Time.”


Representative Image #1 Text, My Clock Dimensions but not the Movement in my Clock. 

“The Original Pendulum was Much Longer than the one in this Image, these are the Scrape Marks from it. Scraping is not Normal, the Original Clock Movement would not Work if it was Scraping, these were probably from Handling the Clock, or from a Longer Decorative Pendulum. This is the Compartment that you Open to Stop, Start, or Adjust the Pendulum Bob (Circle Part) for the Original Movement, but with a Decorative Pendulum, other than Push Starting it after the Clock is placed on the Wall, it’s not likely that Access will be needed.”


Representative Image #2 Text, My Clock’s Face Cover Opens like this, but my Clock is Circular and it is Longer Below the Face. 

“My Clock Face looks like this, with a Glass Cover that Lifts in this way, but the Face of my Clock is Round, and the case of my Clock is Longer. My Movement is Set by Moving the Minute Hand Forward. Replacement Movements usually Require the Clock to be removed from the Wall and a Small Setting Knob Turned to Set the Time. On my Clock if I need to Set the Time Back, I stop the Pendulim for the Required Time then Restart it.”


Representative Image #3 Text, An Automotive Clock Movement from Years Ago. 

“This is a Classic In-Dash Clock as found in older U. S. Cars. I remember sitting in my father’s car and hearing a periodic click coming from the clock.

Look near the Tip of the Tool in the Top Photo, there is a set of Electrical Contacts that are closed. When the Contacts Close enough to complete the Electrical Circuit, they briefly Power a Solenoid or Magnetic Device with 12V that Pulls the Contacts Apart a Distance, and in doing so, they cock or tension a Clock Spring that slowly forces the Contacts back together, and also Powers the Clock.

In the Bottom Photo, the contacts are separated, (the clock will Run even if Manually Pushed Apart by the tool), and as the Clock Mechanism Runs, the Tips Sl Slowly come back together until the cycle repeats and some child also wonders what that periodic click is.”
