1941 Obituary 
"IT is with great regret that we have to record the death at his home at Somerfield, Holmfirtb, near Huddersfield, of Mr. Francis Edwin Brown, chairman of David Brown and Sons (Huddersfield), Ltd., and it associated companies. Mr. Brown was sixty-seven years of age. He joined the company, which was founded by his father in 1860, a an apprentice in January, 1889, and the business of David Brown and Sons in it present form was originated by him.
He was a pioneer in the development of machine-cut gearing, which was a logical outcome of the first machine the company used for cutting teeth in the wooden gear patterns in which it at that time specialised. The next step was the adoption of the same machinery for cutting the teeth in mortice gears, in which hornbeam teeth were wedged into cast iron bodies and the teeth afterwards machine cut.
Mr. Brown's earlier experience covered the period when tooth shape were determined on the drawing board and methods of generation were unknown. Experiments were at first based on cycloidal formations, and various rolling circles were used for different trains. A number of odontographic methods of tooth shape determination were employed and many special forms, such as " G " teeth, were tried, but it was in no small measure due to the efforts of Mr. Brown and his colleagues that standardisation was achieved. He early realised the possibility of cutting teeth in metal patterns, and then in the actual running gears. This development led to the acquisition of the site of the present Huddersfield works (Park Works) in 1900. In 1903 he prepared the first general gear catalogue issued by the company, which came to be regarded almost as a text-book on the subject.
The wide use now made of worm gearing is, in no small measure, due to Mr. Brown's initiative.In his early days such gearing was regarded as a means of obtaining a right-angle drive of high ratio, but of low efficiency, that was only used as a last resort. Experiments in the use of the correct materials and the parallel development of special machinery gave such successful results that Mr. Brown was able to establish worm gearing for the rear-axle drive of the London buses. Since then worm gearing ha been accepted for all types of industrial and transport transmissions. Much research work was also done under his inspiration on helical gears and the plant for producing them, with the result that the firm was able to offer efficient ships' main propulsion gearing simultaneously with the adoption of steam turbines for marine work..."
