Abstract

307,118. Evans, W. E., (Schiess-Defries Akt.-Ges.). Dec. 7,1927. Milling-machines. - In a machine for milling grooves or slots, the tool f may either be set to the full depth and then traversed across the bed b to complete the groove in a single operation, or the tool may be continuously reciprocated through the work and fed to the required depth by mechanism acting at the ends of the stroke. For the first mentioned method of operation, the tool carrier d is traversed along the non-rotary screw g by means of a nut h which may be driven from the main-shaft s through inclined shaft t, screw gears u change, speed gears r, reversing gearing q and bevel gears p. For reciprocating the tool when the depth feed is to be employed, the drive of the nut h is disengaged and the screw g is bodily reciprocated by means of a crank disc w whose crank pin engages a block in a slotted member i. Lost motion is provided at n and the tool is fed at the ends of the stroke by ratchet mechanism (not shown) operated by cams o on the crank disc.
