He was responsible for many inventions related to lift bridges, pneumatic grain nozzles, reinforcement cableways, and other lifting appliances.
Mr. Walker was born in 1875 and educated at Leeds University, where he later became private assistant to Professor John Goodman, M.I.Mech.E. In 1894 he was articled to the surveyor of the North Riding of Yorkshire and on the completion of his articles, four years later, was appointed assistant engineer to the London and North Western and Great Western Joint Railways, which at that time were engaged on the construction of important new works, including the widening of the Chester and Birkenhead Railway and the enlargement of Shrewsbury station.
In 1902 he became contractor's engineer and agent to the Cleveland Bridge and Engineering Company, Ltd. He remained with that firm until 1912 when he received the appointment of resident engineer to the Port of London Authority. He resigned this position in 1924 and subsequently went into practice as a consultant.
