Patents in clockmaking usually cover innovations to clockworks, the wheels and springs and escapements that together contribute to a clock’s ability to keep accurate time.

In the case of Elias Ingraham, founder of the 19th-century Connecticut company that bore his name, the patents he applied for concerned the design of his cases. In fact, Ingraham won 17 patents between 1853 and 1873, all protecting the design of his clocks, most of which were made to hang flat on a wall or sit on a shelf.

Ingraham was able to devote his attentions to the physical look of his clocks because the technology inside them was rapidly becoming a commodity. By the middle of the 19th century, spring-driven clockworks were replacing weight-based ones, which allowed clocks to be smaller and lighter. Clocks with balance wheels no longer needed to be so tall in order to accommodate a swinging pendulum. These innovations permitted Ingraham to focus on the look of his clocks to differentiate himself from his competitors.

Which is exactly what he did. In 1844, he and his brother Andrew partnered with Elisha Curtis Brewster to form Brewster & Ingrahams. The firm would become E. and A. Ingrahams Company in 1852, Elias Ingraham and Company in 1857, E. Ingraham & Company in 1861, The E. Ingraham & Company in 1881, and The E. Ingraham Company in 1885. These minor name changes might seem overly fussy, but they provide the contemporary collector of antique Ingraham clocks with a sure way to date clock styles that were produced during multiple years.

The first Brewster & Ingrahams clocks were called Gothics. Some had rounded tops, and some came to a point, with sharp "steeples" on either side of the clock’s dial. Competitors came up with their own variations on the steeple theme, as did Ingraham himself, whose embellishments upon his original included steeple clocks that were ringed with columns and adorned with rippled molding.

Ingraham's banjo clocks, many in handsome walnut, were also fitted with springs. Ingraham shelf clocks ranged from painted timepieces richly decorated with mother-of-pearl to round Venetian and Grecian styles clad in rosewood veneer and adorned with gilt columns. Versions of these shelf clocks were also created for walls—the Ionic style was so popular that Ingraham made it from 1862 until 1924.

In 1885, Elias’s son Edward took over the company and continued its innovation in clock cases. Double-dial wall and shelf clocks produced during this period told the time of day,...

But Edward’s chief contribution to his family’s company was a patent that covered the application of black paint to wood to create a shiny, marble-like finish. These clocks proved very popular for the venerable firm—some 200 designs were produced until the 1920s.

Ingraham continued to produce wooden wall and mantle clocks until World War II. Between the wars, the company also diversified into pocket watches and wristwatches. But in 1967, Ingraham was sold to McGraw-Edison, which converted its clock factory in Bristol, Connecticut into a production facility to make fuses, which by then was a more profitable enterprise than making clocks.

Key terms for Antique Ingraham Clocks:

Escapement: A device that converts the pressure of a spring or coil into a fixed release of movement.
