Changing a Suspension Spring in a Seth Thomas Model 2 Regulator Clock
In the heart of autumn 2018, a unique piece of history found its way into the hands of a dedicated clock restorer. The object of interest was none other than a Seth Thomas #2 Regulator, a classic timepiece that has graced many homes since its production between 1922 and 1929.
The antique clock, with its mahogany finish, has been running smoothly since its acquisition, keeping excellent time and proving to be one of the most accurate mechanical clocks in the collection. However, like many vintage clocks, it requires regular maintenance to ensure its continued precision.
Over the years, the clock has undergone 77 weight-driven movements, with the last significant servicing happening in the 1940s. Fast forward to 2018, and the suspension spring, a thin band of steel that assists in controlling the rate of the pendulum swing, needed replacement. The restoration expert sourced the replacement spring from Perrins.
The process of servicing this particular clock was a unique experience for the restorer, as it was the first antique clock they had been servicing. The lower section of the case was redesigned in 1922, and the pendulum attaches to the end of the horizontal pins of the suspension spring. The end of the crutch wire goes through the opening in the pendulum, and the hour hand needs to be pushed in far enough to avoid rubbing against the minute hand.
During the servicing, the restorer noticed that the pendulum swing had slightly more amplitude than previously. This could be attributed to the new suspension spring, which was designed to provide a smoother and more consistent swing for the pendulum.
With the bracket screwed back into the case and the clock leveled on the wall for observation, the restorer could see the fruits of their labour. The clock, now refreshed and revitalised, continues to serve as a testament to the craftsmanship of its time and a reminder of the rich history of clockmaking.
Despite extensive research, the specific production year of the suspension spring for this particular model remains elusive. Typically, Seth Thomas clocks are dated using movement serial numbers or stamps, but the specific details for this model are not mentioned in the available resources. For precise information, one might need to consult a clock collector's database or contact a professional clock restorer.
As the clock continues to tick away, it serves as a symbol of the enduring allure of antique clocks and the meticulous craftsmanship that goes into their restoration. For the restorer, it was not just a job, but a journey through time, a chance to connect with a piece of history and preserve it for future generations.
The restorer, during the servicing of the antique Seth Thomas #2 Regulator, discovered that the new suspension spring, a replacement from Perrins, contributed to a smoother and more consistent pendulum swing, leading to a slight increase in amplitude. The restoration expert found this process particularly unique, as it was their first venture into the world of antique clock servicing.
