The Dukes & Briggs Engineering Company were manufacturers and suppliers of custom built electrical equipment including stroboscopes, timers, power supply units and network analysers. In 1955 Philip Harold Briggs and Kenneth James Butler invented a device for measuring the speed of yarn, which the company patented jointly with the British Rayon Association. Other patents were later registered for a rotary flowmeter (1963) and a new or improved flow-responsive instrument for use with fluids (1969).

The company was acquired by Sir W H Bailey & Co Ltd in 1968.
