Rosewood Seth Thomas (Thomaston) Ogee Clock - Part 1

I'm starting this off with the restoration of the movement, simply because I haven't photographed the finished case yet. The "before" photos can be seen in this post: Most of the clocks that I bought from this sale (now a good client of mine) were in relatively decent shape, yet still in need of work. Either case restoration, movement restoration, or dial restoration (or all three).

On this Seth Thomas clock, it needed all three. The dial had been very poorly repainted, the veneer had chips, and the movement (which is the subject of this post) was not in excellent condition.

Here is the movement "as found". Overall not too bad, but in need of some attention. This is a Type 1.242 movement. Note the use of screws to fasten the top plate, and the semi-circular projection on the plates by the time second wheel pivot. I wasn't able to find manufacture dates for this specific movement, but I would guess early 1870s.

Note hole-closing punch marks (not repairable), and a few new bushings.

Lots of solder, and note the damage to the screws.

A creative (and strong) repair to the crutch wire. While this is certainly strong and durable, it is far from elegant.

Upon disassembling the movement, I discovered that the fan wheel had been soldered.

I don't know why the escape wheel bushing is so ridiculously long. With a larger surface area (metal on metal contact), the clock needs more power to drive it. This is one of the reasons why clocks with very thick plates have deeply cut "oil sinks" for the pivots. In those cases the plates are thick for strength (and looks) and the "oil sinks" are to reduce the thickness and contact area. In this case, the bushing is twice as deep as it needs to be.

Most of the work on this movement (even though it looked rather bad) was simply cleaning and solder removal. On the areas where the solder was just a very thin film, abrasives were used. I used very fine sand paper (maybe 320 grit?) followed by finer grit, and #0000 steel wool. On any heavier areas, the excess solder was heated and "brushed off" the surface before sanding and polishing.

The excessively thick bushing was filed down, and given a light peening. This closed-up the pivot hole slightly, so it was opened-up again with a cutting broach.

The following photos show the repaired (cleaned) areas before cleaning the movement and wheels in cleaning colution.

I don't have photos of the fly wheel repair, but the solder joint was a cold one, and I was able to take it apart easily.

The crutch wire repair was done using a half-lap joint (splice) using a new piece of brass wire. You can spot the joint just over the spoke of the main wheel.

In addition to this, the screws were repaired (mangled sections cleaned with a file, and new bluing applied).

The movement did not come out of the cleaning solution as nice and shiny as I had hoped, so the parts and frame were given a light polish with #0000 steel wool.

Quickie Update

A few things to briefly mention:

- The John Birge column & cornice clock is nearly finished. I just put a few more hours into the crown moulding over the past 2 days, and it's NEARLY finished. I still need to cut and install two triangular glue blocks, as well as drill the screw mounting hole on the replaced left crown piece. Once that's done, I can glue and install the crown, and the clock will be done. I also had to entirely re-make the fan wheel a second time (more details on this later).

- I've been working on the Rosewood Seth Thomas clock (from this clock haul). The rosewood case is restored (and looks fantastic), the dial has been repainted, the movement is repaired (and fully functional), all that is left is to finish working on the reverse glass painting (tablet). The clock originally had a very thin old mirror, but I really didn't want to have a mirror in it.

- I recently completed (99%) the restoration of a wonderful and cute miniature wag-on-the-wall clock. This one mostly just needed cleaning and new side doors, but during the cleaning and restoration, I had to repair/reshape the dial mounting hooks, and I also made a custom wall shelf for it. The only reason it isn't 100% finished is that the chains on the clock are too short. The clock runs and strikes fine, but there is only enough chain for about 10 hours (both chains are less than 3 feet, and they need to be at least 5 feet long). The chains needed are 50 links per foot, which are not commercially available. The closest match are 49 LPF, so I may try those.

- I may also be painting the tablet for the rare 8 day Seth Thomas column clock. The stencil has already been cut for it.

A Wonderful Donation

I had a client who dropped by last night for me to look at one of his clocks (a typical 1930s or 40s balance wheel Westminster clock), and he gave me this clock:

At first I was thrilled, but having a closer look at it, I could see why he wanted to part with it. He told me it didn't run well, and it would strike continually. He was going to THROW IT IN THE GARBAGE, but he thought I might want it for parts.

While the clock certainly has a plethora of issues, I'm very happy that I'm able to save it from the landfill and put it right again. I'm excited to work on it, but at the same time, I also have too many other projects started right now, so it will have to wait.

The clock is a Black Forest (German) Wag-on-the-Wall clock with a "shield" dial. These are fairly common, but the primary value is in their beautifully painted colourful dials. Many consider them great examples of Folk Art.

This one is gong-strike with steel arbours (the very early ones have wooden arbours and strike on a bell, or occasionally even a glass bell with a wooden hammer). The dial on this one is roughly 13" x 9.5", which makes it a "medium" sized clock. I also have a miniature one, and there are larger ones (16" tall or so).

Both side doors are later replacements made from cigar boxes.

Replaced gong from a mantle clock. One of the major problems with this clock are the screws that were added everywhere. These have unfortunately permanently damaged all the plates and components. Luckily, all the gears and levers are original and present. I was also especially happy that the chains are still with it. Matching a chain can be incredibly difficult.

The dial, top plate, and backboard have woodworm damage. This doesn't dramatically affect value, or the integrity of the piece, but I will have to carefully check that there are no active beetles left in the wood, and add a chemical treatment to be extra safe. Woodworm (a small beetle) is a common problem with antique European clocks and furniture.

There is what appears to be either yellow glue or epoxy on several parts of the wooden frame and back.

The entire movement box has a rake to it (from loose joints and a poor regluing effort) so foam pads were added at some point in an effort to straighten the clock. The foam may also have been to dampen the sound of the gong.

This glue will be hard to remove. I may need to soak the wood in water, or use strong chemicals. Again, there are screws everywhere.

You can really see the rake in this photo, and how all the wheels are angled from the slope. Also note the metal "L" bracket in the lower left.

The clock came with "parts" but all of them are "make do" replacements. The pendulum is especially rough, and far too heavy (there is a lead plate on the rear). The weights may also be too heavy, and I'm not sure why one is so much larger than the other (they should be the same).

There are dates everywhere from the last person who "fixed" this clock. The dates are all around Nov 9, 2004, Nov 11, 2004, Nov 12, 2004, etc.

The weights were a bit creative. Large diameter copper pipes filled with lead. They look fine, except that they should be brass or cast iron.

The shield dials on these Black Forest clocks are normally curved. I don't really know why they chose to make them this way, but I have seen plenty of examples, and they are almost always curved. At some point, someone must have thought that this dial had simply become badly cupped, and they "fixed" it by flattening it and gluing large wooden stretchers on the back. This is probably what caused most of the cracks and damage to the dial. There are large cracks and losses to the paint and gesso. This also makes the hands stick out quite far away from the dial.

There is actually such significant paint loss and stress cracks that the area above the 7 shows a piece of German newspaper that had been used as a patch over a knot in the dial before the gesso was applied. I will take detail photos of this later.

The knot is visible on the reverse.

The dial and paint are so fragile that I'm not sure if I want to attempt to remove the stretchers and repair the curved profile. The dial is badly damaged, but it's not so bad that I can't live with is as-is.

The movement appears to be unsigned/anonymous (a name can sometimes be found on the top verge retainer piece, or scribbled somewhere on the movement in ink). A large number of these are unsigned and difficult to date. I would guess this clock to date ROUGHLY around 1860-70. The very old ones with wooden arbours can date as early as 1780 especially if they have glass bells. Some are musical as well with multiple bells. Others incorporate moving figures.

The plan will be to take the entire thing apart, repair all the wood (plug screw holes and repair cracks) and then re-assemble everything with hide glue. New side doors will be made, and proper weights and a pendulum will be ordered. Once the clock is all cleaned and put back together it will get a custom wall shelf so that everything is properly supported. I'm not sure when I'll work on this clock, but stay tuned!

Again, I want to stress that despite all the problems, I'm thrilled with this freebie!
