In 1914 W. D. Forbes, writing in the US magazine 'Machinery', wondered how an English patent on a new type of screw head never became popular. It had a cross head and an appropriately shaped screwdriver. It had been shown to him 'years ago' by T. A. Weston. It is not made clear whether Weston was the inventor.[7]
Obituary 1909 [8]
WE have to record with regret the death of Mr. Thomas Aldridge Weston, which occurred on May 3rd at St. Luke's Hospital, New York. Mr. Weston, who was born in Birmingham in 1832, was the inventor of the Weston differential pulley block, and he was also responsible for various other improvements in connection with mechanical engineering work. Weston pulley blocks are manufactured in England by Tangye Brothers and in America by Yale and Towne and Co., and by the Brown Hoist Company, of Cleveland, Ohio. For many years Mr. Weston was associated with the former American company.
