Description:
Note: Early English patents (pre 1916) were numbered by the year and started at patent #1 at the start of each year in January. The patent # used in DATAMP represents the year of issue of the application and the patent #. This patent is #11,413 of the year 1912.

Abstract:

A planing- machine drive consists of gearing by which the lay shaft of a changespeed box is used to give different cutting speeds while the main shaft gives a direct constant return speed drive, or to give different cutting speeds on both forward and return strokes when d o u b l ecutting. The main shaft A driven by a pulley J passes through the change-speed box E and carries a pinion A<1> on its end in gear with a pinion A<2> loosely mounted on an independent shaft C which also carries a double clutch portion D fixed to it and another loose pinion B<2> on its other end. The lay shaft B is adapted to be driven at different speeds and carries at its forward end a pinion B<1> in gear with the loose pinion B<2>. The pinions A', A<2> are proportioned to give a quick return drive to the shaft C which, through worm gearing G, G', drives the main spindle G<2>, In a modification, Fig. 4, in which the reversal can be effected at different speeds for cutting in both directions, the lay shaft has a further pinion B<1Î> adapted to drive at different speeds a pinion A<2Î> on the independent shaft C through an idle pulley which is mounted at one end of a lever K, while the main shaft pinion A<1> is mounted at the other, so that both pinions cannot be in mesh at the same time.
