Gleason Works
of Rochester, USA, with factories overseas making machines for producing gears, and inspection gauges. UK branch in Plymouth.
Founded by William Gleason in Rochester, NY.
1908 'Messrs. Gleason, of Rochester, U.S.A., have made machines for planing the teeth of spur-gears up to 24 ft. in diameter by 24-in. face and 6-in. pitch. A former-plate is used as in Potts’ original system. The large pitch-gears usually cut on these machines are generally cast with teeth sufficiently thick to allow for machining. This reduces the weight of the castings, saves the time otherwise spent in stocking out the teeth, and the teeth are freer from sponginess owing to there being less metal in the rim. Fig. 21, page 224, shows one of these machines capable of planing wheels up to 15 ft. in diameter at the works of Messrs. David Brown and Sons, of Huddersfield, and similar machines are used by Messrs. E. Arnold Pochin and Brother, of Manchester.'[1]. 'Potts' may have been William Potts and Sons.
