TH Brigg & Co (Iron Founders) was established about 1883 At Westholme Works, Westholme Street, Thornton Road, Bradford, Yorkshire, UK.

The company flourished for about 50 years under the management of Thomas Hargreaves Brigg and younger brother William. Specialising in the manufacture of textile machinery the brothers appear to have made a tidy living based on the success of the curiously entitled "Briggs Improved Letting Off Motion". An advert from the 1883 Bradfod Postal Dirctory is pictured below.

William died in 1930, I don't know about Thomas but without their leadership and the UK heading into recession, the company failed sometime in the 30s.

I would be very interested to hear from anyone with any knowledge of this company.
