John Smith Raworth (1846-1917) was an electrical engineer of some renown. After earlier employment with R & W Hawthorne in Newcastle, Wren & Hopkinson in Manchester and in the 1870s a spell with Siemens, he became Chief Engineer with Anglo-American Brush at their London office.
After Brush’s takeover of the Falcon Works in Loughborough, he became Superintending Engineer there and, from 1891, General Manager. In 1897 he became a part- time consultant on the board of Brush and from 1896 he was Technical Director on the main board of British Electric Traction (BET). He was on the board of the North Staffs Tramway company where Emile Garcke, the BET Managing Director, was chairman.
He also became chairman himself of the tramways at Devonport, where he experi- mented with his regenerative braking principles and at Southport where he tested his prototype demi-car.
On 1 October 1904 John Smith Raworth registered his own company, Raworth Traction Patents Company Limited, to exploit his existing and future patents in respect of regenerative braking and small efficient tramcars.
