Ingraham Kitchen Clock

In for repair is an Ingraham kitchen clock. A short history of the Ingraham Clock Company. The report from the customer was the strike side mainspring would not wind.  The glass was loose.  The time side worked fine.

This short video demonstrates the wear and dirt within the  pivot holes on this clock.

As mentioned above one of the main reasons for this clock to be repaired is the mainspring click on the strike side.  The image below shows the original click.  The click itself was also damaged.  This was caused by the click mechanism not working properly and the power of the spring let go way to fast.  The original click was not the correct style for this movement.  The click used was too weak causing the failure.  The replacement click on the left is much beefier

These next two images demonstrate the escape wheel pivots.  Both usually are identical but in this case they are not.  The first image below is a replacement pivot.  Notice this pivot is thinner and a little longer than the image below this one.

After all repairs has been completed, the pieces and parts are ultrasonically cleaned. 
This image shows the cleaned plates, wheels, and levers ready to be assembled. 

The assembled movement being tested  This process lasted 2 days.  The only adjustment needed at this juncture was to adjust the count wheel lever.  

The case was cleaned and oiled with hi grade wood oil, the glass was loose in the frame.  The glass was held in place with a wood strip.  This was reinstalled.  The glass is nice and snug.  The glass was also cleaned.

The movement was then installed in the case.  At this stage, the case is leveled and the pendulum crutch is adjusted so the tick/tocks are evenly spaced.  This is called putting it in beat.  This process is done at this time because once the face is installed, it is harder to make this adjustment.  The strike hammer was also adjusted at this point.

After the movement passes this test, the face and hands are installed.

The clock can now be regulated or adjusted for fast or slow.  This adjustment is completed by changing the length of the pendulum.  There is a nut at the bottom of the pendulum that can be tightened or loosened  to adjust.

A nice looking clock. 
Once this process is complete, the clock is ready to go home.

Another smooth running clock!
