William Potts and Sons
From Graces Guide
Guildford Street, Leeds.
1908 Fig. 17, page 191, [see above] is a photograph from an old drawing of the first gear-shaping machine, designed by Mr. Potts, a member of the celebrated clock-making firm. It is described on the original drawing as “Potts’patent wheelcutting and dividing engine for cutting the teeth of bevel and spur gearing mathematically correct. Manufactured by Shepherd, Hill and Co., Leeds.” This machine appears to be the first attempt at planning or shaping bevel and spur gear-wheels from a large former-plate. A gold medal was awarded for this machine at the Paris Exhibition of 1867.'[1]
