Description
Corliss, in his patent, explained that "the model of operation of my improved machine is analogous to that of the machine set forth in the patent to me, dated March 10, 1849. The machine is adapted to cut bevel-gears of large size, with any required bevel, and gives the proper forms to each tooth, with the same contour of the tooth through-out....My machine cuts, like its predecessor, one side of each tooth first; it is then readjusted, and various parts, including the templet, are reversed in position to dress or cut the other side of each tooth." (Patent Number 190,470)
