They specialized in small motors, fire alarm systems, telegraph-related products, and various other electric devices.

In 1891, the company built an electric car that sat four people and moved approximately 16 MPH.

It was the first to feature a steering wheel, and is known as the first successful electric vehicle in America, though other unsuccessful prototypes had been built before.

Around the turn of the 20th century, the company branched out to create various telephone/telegraph-related products, clocks, and fire alarm systems.

In 1972, the company officially closed and sold the remainder of their lines to Eastern Air Devices based in Dover NH (Now known as Electrocraft).
