Description:
Daniel Breed - patent attorney

My invention consists of a rack-gear provided with elastic bearings and used with planing, jointing, and other machines run by means of a rack-gear, for the purpose of graduating the stopping and starting of the table at each change when thrown back and forth, and thus prevents the noise, jumping, and jar occasioned by the abrupt changes in ordinary machines of this description as heretofore used.
