The Gyro 100 years on

Silicon Sensing's 100 year pedegree of gyro manufacture.

1850
Singer old logo

Singer old logo

The Singer Corporation, first established by Isaac Merit Singer in 1851, was later to acquire a company at the roots of the Silicon Sensing family tree; Kearfott, in 1968.

1854

Timex old logo

Timex was founded as Waterbury Clock Company in 1854 and much later became involved with gyroscopes (clockwork ones) in 1953, later to be acquired by Bendix.

1860

Elmer Ambrose Sperry

Elmer Ambrose Sperry was an American inventor and entrepreneur, he was most famous as co-inventor, with Herman Anschütz-Kaempfe of the gyrocompass.  We regard Elmer Sperry as the founding father of inertial products business we have today.

1870
1870

Goodrich

Dr. Benjamin Franklin Goodrich establishes the first rubber company west of the Allegheny Mountains, leading to Akron, Ohio becoming the rubber capital of the world.  140 years later a descendent of this company went on to buy the BAE Systems Inertial Products Division.

1880
1886

GEC

The General Electric Company or GEC was founded in 1886. It was a major industrial conglomerate, involved in consumer and defence electronics, communications and engineering.  In 1988 it acquired the Plessey business, the gyro arm of which can be traced through Singer back to Kearfott in 1917.

1900
1901

General Gas Light Co.

Alfred Humphrey opens General Gas Light Company in Kalamazoo, Michigan, marketing new, inverted arc gaslights.  The Humphrey company, much later, manufactured spring and gas powered gyrsocpes used in aircraft and missile guidance.  Eventually bought out by Allied Signal in 1985.

1908

Gyrocompass System

After many years of work, Sperry produced a workable gyrocompass system in the United States. Several attempts had been made previously but they suffered technical problems, including the Steaming Errors, where rapid changes in course, speed and attitude cause deviation before the gyro can adjust itself.

1908

Gyroscope, the key component of the gyrocompass

“I am a firm believer in the future of the gyroscope. Not only will it guide our ships, but it will have other important and far-reaching bearing upon their operations. ... I would not be surprised if this instrument which for centuries has been a scientific toy and a “plaything of mathematicians should become one of the most useful in the arts and industries –”

1909

Plane Tires

Goodrich enters the aerospace industry with aeroplane tires.  This move paved the way to other aerospace business and technology interests of Goodrich culminating in acquiring BAE Systems' gyro business in 2009. 

1910
1910

The Sperry Gyroscope Co.

The Sperry Gyroscope Company was founded by Elmer A. Sperry to manufacture Sperry's gyrocompass. Three years later in 1913, Sperry Gyroscope Limited was established in the UK. Production in Britain of the Sperry Mk.1 Gyrocompass began shortly after.

1911

Unit Number 100

The first Sperry gyro (Unit Number 100) was installed aboard the Old Dominion Line PRINCESS ANNE for a trial run from New York to Hampton Roads, Virginia. After completing the trial the unit was brought back to New York and installed aboard the U.S.S. DELAWARE. 

1911

U.S.S. Deleware

Trials aboard the DELAWARE were launched starting on August 18, 1911. After the trials an order for four systems soon arrived from the U.S. Navy and Sperry Gyroscope was a reality. The first serially produced unit, Serial Number 101, was installed aboard the U.S.S. UTAH on November 13, 1911. Another of his gyros was installed aboard the U.S.S. DRAYTON.

1912

Gyroscopic Car

Testing of the gyroscopic car, well today we'd call it a self-balancing motorbike. A large spinning mass provided the gyroscopic forces to keep the two-wheeled car upright.  It never took off, but in a way nearly 100 years later the two-wheeled Segway Human Transporter is a derivative of this conceptual mode of transport - see 2001.

1913

Sperry Factory

The Sperry Gyroscope Company Limited was founded in the U.K. It started with a factory in Pimlico, London in 1913, manufacturing gyroscopic compasses for the Royal Navy. Production in Britain of the Sperry MK1 Gyrocompass commenced shortly after.  We regard this major event to be the birthplace and time of our present day company.
