For What Reason did Manufacturers Stop Making Electric Wall Clocks?

The electric wall clock was a popular accessory in the late 1800s. These timepieces were built to keep perfect time for a long period of time. Demand for these goods, however, gradually waned over time. One day, factories just stopped making them.

Clocks that are Electromechanical

Mechanical, spring-driven clocks were the standard in most homes during the 19th century. Accurate mechanical clocks have a mainspring that has to be wound on a regular basis.

Clocks might now have electrical power thanks to early dry cell batteries. The initial battery was bulky and costly. As a result of these issues, several clock and motor designs emerged.

Timepieces with quartz crystals are the most intricate. Better still, they may be had for less money without sacrificing quality. They aren't always reliable, though. A lot of the circuitry is complicated and prone to failure.

Although they consume more energy, synchronous clocks are substantially more precise than their quartz counterparts. They're dependent on the AC power grid's utility frequency, too. These timepieces have a very long accuracy rate.

There were various issues with switching in electric clocks. In addition, they made some very big mistakes on the spur of the moment.

Clocks that are Able to Keep Time with One Another

Timepieces with synchronized electric movements were all the rage in the 1930s. They did not cost as much as mechanical ones and needed almost any maintenance to run precisely.

As confidence in the stability of the electrical grid grew, so did the use of synchronous clocks. While several variations of clocks were manufactured, the synchronous electric clock and the quartz clock were the most popular. A stable supply of alternating current is essential for synchronized electric clocks. The frequency regulation system at the power company is responsible for this. Any deviation in frequency will cause the synchronous electric clock to lose accuracy.

Although there were types that were self-starting, synchronized electric wall clocks do not work that way. After the power was restored, others had to be restarted manually. If there was a power outage, a "wavy line" or "outage" symbol would emerge.


The corrosion of one or more of the batteries has likely caused the failure of countless electric wall clocks to accurately display the time. They are hanging in a damp, high-humidity area, so this is to be expected.

It's important to know what occurs if this kind of corrosion is allowed to keep going unchecked. The metal's integrity degrades, which ultimately affects output. The good news is that there are various strategies available for protecting against or lessening the impact of this. Efficacious pigging and pharmacologic inhibition programs are one option. To use the proper drilling fluid is another method. It's crucial to be aware of the dangers included in both crude oil pumping and piping. Metabolites, high speeds, and suspended debris can all be quite damaging.

In fact, certain microbes may lithotrophically thrive on iron metal. Some organisms can provide the necessary energy by combining the oxidation of Fe0 with the reduction of sulfate.


The Herschede grandfather clock brand was established in 1885 and quickly became well-known for its reliable timepieces. The clocks made in Herschede are still highly sought after by collectors today.

The business manufactured a number of timepieces, including "petit" clocks that were shorter than seven feet. Crown Clocks, a line of affordable electric timepieces, was also released. The corporation established regional offices in Chicago, New York, and San Francisco in the early 1920s.

Several honors were given to the Herschede Hall Clock Company at the 1904 Louisiana Purchase Exposition in St. Louis. The tube chimes on this thing won a silver medal. Charles Eisen, a composer, was commissioned to create a clock mechanism for the canterbury that would play chimes. There was a tiny mirror next to the clock so that you could check the time without getting up.

In addition to their clock factory, the Herschede Hall Clock firm also occupied the building next door. Until 1970, the facility was used to produce clock movements for electric clocks sold by the firm.


Revere is known for producing several notable brands, including Contempora (#7100), Designers' Group, and Vista. There is a wide range of aesthetic and structural variation across these lines.

New phenolic handles with protective finger protectors are available in the Designers' Group collection. The non-stick inside helped it gain a reputation as cutting-edge kitchen equipment in the United States. Double boiler inserts were also part of the collection.

The Designers' Group's Contempora (#7100) collection likewise featured sharply angled contemporary profiles. In 1971, this brand-new series made its debut. The strainer tops were similarly made of stainless steel. It also had a single-piece grip for convenience. In 1986, production ceased on the product.

If you were looking for Revere's best cookware, it might be found in the Designers' Group. The bodies in this range were either copper covered or stainless steel. New phenolic pull rings and handles were also introduced.
