 POUVILLON RESTORATION PROJECT - August 2011

Reassemble main movement all components between main frames.

Pouvillon-18-000.mp3. Photo 18 001. We have the universal assembly for the center seconds drive. Photo 18 002. Another view of the components for the little universal joint. The fourth screw, the lower screw, is a replacement and they are too long and the head is too thick, this is to be rectified. Photo 18 003. We have the assembled universal.

 

Photo 18 004 is the beginning or the first stage assembly of the main movement. Photo 18 005 is another view of the first stage assembly.

Pouvillon-18-005.mp3. Photo 18 006, is the assembled universal joint. We can see the pin wheel, or the escape wheel just below the plate and obviously the pinion. Photo 18 010. Another view of the assembled universal joint. As you can see we have the next frame assembly placed above it. And the upper pivots, the upper arbors are all loose as you can see they are all off center in the frame clearance holes. Photo 18 012. Here we have a further stage of frame assembly. We’re starting to work our way through the strike train at the lower end of the frame on the left end of the picture.

Photo 18 013. Just another view from the bottom of the clock. Photo 18 014. The point of this picture is to show the aligning center punch marks or countersinks where the large four spoke pinion is meshing with the count wheel. This follows right through the strike train and makes setting up this strike train extremely easy. Because once you assemble the frames and everything is in place, the strike is totally synchronized. Photo 18 015. In the hub of this gear we can see right on the left hand side the nut that holds it to its arbor and below it in the shadow we have the pinion. You can see Mr. Pouvillon cut away the intersection between the two spokes to expose the locating or the matching center hole or punch hole in the corresponding tooth in the pinion that matches with the center punch mark in the rim of the brass gear.

Photo 18 016. Here we have the next two sets of gears in the strike train. Again you can see each pinion and gear has a matching center punch which phases the whole train correctly. Photo 18 017 is a photograph to show porosity in the casting used to make the gear. Also of note in this picture is, what I would call, bad rounding of the ends of the teeth due to some previous restorer or possibly Mr. Pouvillon, excessively polishing these parts. Photo 18 018. Another picture to show the porosity in the casting.

 

Photo 18 019 is the complete time and strike train assembled in their frames. Photo 18 021 is the main frames assembled on the base plate.

 

The rest of the photos are just general pictures of the complete movement mounted back on its base. It’s interesting to note the reflections in the base plate and also the brass surround. Sometimes as you walk around the movement now, one has the effect of this whole assembly floating on the surface of the base. There is a further discussion about the design of the frame.
