I bought four clocks at an estate auction several weeks ago, this and three other Ogee clocks plus a parlour clock. This clock is no less interesting than the others but I was lucky enough to research its maker and date it fairly accurately. I wish I knew its provenance but nevertheless it is an excellent example and has been well cared for over the years.
It is a Chauncey Jerome 30 hour Ogee weight driven time and strike clock. No-one can deny that Chauncey Jerome had made a historic contribution to the American clock industry in the 18th century when he substituted brass works for wooden works and was said to be “the greatest and most far-reaching contributor to the clock industry.” Although he made a fortune selling his clocks, and his business grew quickly his company failed in 1856.
The number 11 Ogee was the last of the Jerome clocks made in 1855. Mike Bailey, a Chauncey Jerome clock collector has an excellent blog in which he meticulously details and dates Jerome cases and movements. After researching his site I was able to determine that my clock is a number 11 Ogee made just before the Jerome bankruptcy, 1855. It has the Jerome patent 30 hour brass movement number 1.314 which is likely original to the case.
There were some issues with the movement as you would expect from a 156 year old clock. There were a number of punch marks here and there, but specifically on the first wheel and the second wheel time side. The movement had years of dirt. The repairs over the years are typical for this type of clock. Punching to close pivot holes would have been the preferred approach to repairing a worn clock. With the advent of the modern bushing machine repairs are much simpler.
Eight bushings were installed. The first wheel strike side, the second wheel strike side plus the fly, the lower gear off the centre cannon, rear plate and 3 bushings on the time side.
A piece came off the wood support for the movement when I disassembled the movement. Dry-rot perhaps. I had leftover hide glue from a previous project, applied the glue and clamped it for 24 hours.
The retainer clip for the count wheel was riveted in placed and prevented me from taking it apart.
Some were punched very close to the pivot hole as you can see in this next photo. I left that as-is and decided to take a second look in a year or two.
After eight bushings were installed (4 in the front and 2 in the rear) and an ultrasonic cleaning, the parts are test fit to check the smooth running of the gears. The rope for the weights looked re-usable, they were not replaced. The suspension spring also looked to be in good shape. The crutch wire has had bending and twisting over the years but it was also re-usable.
Now to regulate the movement. The clock is ticking away nicely and in beat. There are always challenges setting the strike side and this movement is no exception. However, through trial and error the strike side is functioning as it should.
These are very simple clocks to service and a great movement to hone your clock repair skills.
