Waterbury Regulator

Waterbury Regulator Clock

In for repair is a Waterbury regulator clock.  Here is a picture of the clock as it was brought into the shop.  This is a nice looking single train timepiece.  This is a timepiece because it does not play a tune nor strike the hour or 1/2 hour.
Notice the mainspring hanging out the bottom of the face.  The customer stated that winding the clock there is no tension on the wind and the spring is not building tension.  

This could be 4 things:

1) The click is damaged or broken.
2) The click spring is damaged or broken and causing the click to not engage with the click wheel.
3) The mainspring is broken.
4) The mainspring end(s) have disengaged from the barrel post.

Here is the clock with the face and hands removed.  The movement and case are probably a marriage for a couple of reasons:
1) There are two sets of movement support holes. 
2) The case looks more like a turn of the century case but he movement says WWII vintage. 

I will fill the screw holes and add 2 more screws to make sure the movement is secure in the case.  The case looks like it is a turn of the 20th century case but the movement looks newer.  The plates are made of steal with brass plating.   During WWII brass was in short supply, movements were made of steel at that time.  This movement is classic of that time.

A short video of an initial inspection of the movement in the case.  

A close up the the manufactures name

The next few images show the clock taken apart and some of the items that need attention.  This image shows the minute arbor.  Notice the rust on the shaft.

This image shows the cleaned minute arbor.

A sample of the grime on the click and click wheel.  It is almost impossible to see in this image the click wheel because of the diry oil.  Once the winding mechanism was cleaned.  The click, click spring, and winding arbor were inspected.  They are in good working order.  When mainsprings brake, it is very common to see damage to other parts of the movement.  In this case, nothing was damaged.

Here is an image of a couple wheels.  Notice the dirty oil in the trundles of the lantern pinion.

More dirty oil around the mainspring

The following images are of the broken mainspring.  The mainspring broke close to the inner loop.

The inner spring nib was rather difficult to remove from the winding arbor pin.  Mainly because it was so greasy and there was not much material to grab onto to remove the spring.
These images are of the clock after cleaning.  The clock was cleaned via an ultrasonic cleaner with hi-grade clock cleaning solution.

Looks pretty shinny.  Notice the winding wheel (with mainspring attached).  All the grease and grime has been removed.  also notice the plate on the top of the image.  You can see where the brass platting has worn off.

All pivots were inspected for roughness.  All were in good shape.  If they were rough, these pivots would be polished.  After the clock was removed from the cleaner and dried,  pegwood was used to remove any residual residue from the pivot holes.

The clock was then assembled.

Here is a short video showing the clock assembled and running on the test stand.
