What is this clock thing for? #4 – the Geneva stop

You will not see Geneva stops on many clocks but if you do here is an explanation of how they work and how to set up the stops.

Most American clock movements do not use the middle portion of a long & powerful spring but use most, if not all of the mainspring. Geneva stops address this power issue. They are found on better quality antique movements made by American manufacturers. They are set so that when winding the mainspring you can only wind so far and then no further. As we know, clocks can’t be “over-wound” and this lets you know where the definite stopping point is.

On weight drive clocks Geneva stops are used to prevent undue force coming on the pendulum by jamming the weight against the seat board.

Stop works are used as a compromise by utilizing only the middle portion of a long and powerful spring, which varies too much in the amount of its power in the fully wound and completely released positions to get a good rate on the clock if all the force of the spring were utilized in driving the movement.

Removing the stops will do no harm to the movement but it will not release power as originally intended

You will notice a long “finger” (long point of upper star) on one of the Geneva stop gears and a wider gap (shallow groove of lower star) on the other. You set these up so that when the proper number of turns are completed the long finger meshes with the wide gap, thus preventing any further turning.

You will need a letdown set to release the springs

Setting up the Geneva stop

Wind up the spring and then let it down slowly until the stop work is locked, counting the number of turns and writing it down. Then, hold the spring with your let down key and remove the stop from the plate; then count the number of turns until the spring is down and also write that down. Alternatively, wind the mainspring until it winds no further, release the mainspring with your letdown key one complete turn and set the stop. It may take more than one try to set it up correctly.

Don’t worry if they have been removed

On many antique clocks these have been removed because the repair person did not know what to do about properly setting them up.

E. N. Welch Whittier model parlor clock Part IV – final word

In a previous article I described some of the challenges I had with this E.N. Welch clock movement.

The clock ran for about 48 hours and suddenly stopped. It seems that every time I think everything is going well, something else crops up.  I dis-assembled the movement (again) and installed three more bushings, one of which is on the escape wheel bridge which I noticed had a fair amount of play. Perhaps the vertical motion of the EW was causing the clock to stop. The other two bushings were installed on the third wheel, back and front. I have decided to hold off addressing the EW teeth if the bushing work I have done has solved the stoppage issue.

I was hoping to wrap the servicing up fairly quickly but unanticipated problems continued to crop up. Having completed the work mentioned above I could see that things were beginning to change for the better.

The time side ran strongly for eight days after which I reinstalled the strike train. Here is the movement running on a test stand.

Setting up the strike side required manipulating some of the lever wires which were moved out of position by the previous owner, for whatever reason. A previous repair/adjustment resulted in the lifting levers bent back into the case and the count lever pushed in an upwards orientation. As a result I had to bend the levers back into their original positions.

It should now run reliably for years to come. A frustrating project with a satisfying ending.

E. N. Welch Whittier model parlor clock Part I – E. N. Welch history

Among the most common parlor clocks, E.N. Welch clocks are relatively scarce. A key reason is that the company was absorbed by Sessions in 1903. The history of Welch is intriguing, as Welch, Spring & Co. initially focused on producing high-end clocks but eventually shifted to manufacturing cheaper, heavily discounted mass-market clocks—a move that likely contributed to its decline.

This time-and-trike American clock with a count wheel strike is an antique store find. I  found it at what I would call a higher-end antique store in a small village in Quebec during one of our day travels from our summer cottage. I liked it so much I bought it. Because the strike side did not function there was a slight reduction in price.

The clock ran for several days and kept good time, but it was in desperate need of a cleaning. I was unable to get the strike side to run, though I hoped to fix it eventually. All the strike-side parts appeared to be present, but someone had clearly tampered with the levers, bending them significantly. It’s impossible to fully assess the situation until I take the movement apart.

History of E N Welch

The E. N. Welch Mfg. Co. was formed on July 6, 1864 to succeed an older private firm making clocks under the name of E. N. Welch. Elisha N. Welch (1809 to 1887) had been making clocks at a factory site on East Main Street at Forestville, Conn. since taking over the bankrupt business of J. C. Brown in about 1856.

A movement shop was established in 1869, adding to the two factories already in use by the firm. Between 1868 and 1884, a subsidiary firm called Welch, Spring & Company was formed to produce a more expensive line of clocks. The company was formed by three clock enthusiasts; Welch, Solomon Crosby Spring and Benjamin Bennet Lewis. The Welch firm was well known for its handsome rosewood cases, though in 1885, with changing styles in furniture, the surviving firm began to introduce new models with solid walnut cases and discontinued some of the older rosewood veneered cases.

Elisha Welch was enamored of a lovely (but very liberal-thinking) diva of the day from Spain by the name of Adelina Patti. He named his best quality movement after her, called the “Patti” movement. Clocks with this movement are highly sought after by serious collectors. However, Examples of “Patti” clocks at any of the international auction sites are rare.

After the death of Elisha Welch in 1887, the firm steadily declined, selling off some of its assets and issuing new stock to raise much needed capital. A new line of clocks was introduced for 1893, which were cheaper in quality than their already discounted line. In May of that year the factory was closed down and a receiver was appointed The receiver spent nearly two years selling off stock and settling the debts of the firm. It was not until 1896 that the firm resumed production.

In 1899, two fires, one in March and a second in December reduced most of the Welch manufacturing complex to ashes. Despite the completion of a new brick factory in 1900, the company could not meet its liabilities. Meanwhile, members of the wealthy Sessions family were buying out former stockholders and eventually took control of the firm in 1902. They changed the name to the Sessions Clock Company on January 9, 1903.

E. N. Welch clocks made before 1880 are considerably more desirable as these represent the height of the company’s clock-making. Clocks made before 1880 generally command higher auction prices. Compared to companies like Seth Thomas and Waterbury instances of E. N. Welsh clocks coming up on auction sites are becoming quite uncommon.

Stay tuned for more! In Part II, I will describe the Whittier and highlight some of its interesting features. In Part III, I will share my progress and discuss any challenges I encounter while servicing the movement.
