(Cl. 74-81) This invention relates to improvements in washing machines and the like and is directed more particularly to driving mechanisms there for. . extends up into the tub through wall 6. A driven member 30 is fixed on shaft 26. A segment 32 is journalled on shaft 34 and it has a driving member 36 in the form of a curved bar The principal objects of the invention are di GI secured thereto at one end while its other end may slide between lugs 38. rected to driving mechanism which is particu A link 46 has opposite ends pivoted at 62 and larly adapted for washing machines and is char 44 to the| members 26 and 32 so that as the acterized by frictionally engageable driving and member 26 rotates the member 32 swings back driven members whereby a shaft for an agitator may'be driven back and forth through various 10 and forth. The driven and driving members 30 and 36 have inclined frictionally engageable faces angles. . so that the latter may be driven by the former.
