My invention relates to clothes washing ma

. and means for washingl clothes.
In washing machines of the prior art of the
reciprocable agitator type, thorough cleansing of

the fabrics being Washed was impossible, or if
possible, could not be accomplished in as short
a time as desired because the clothes were not
tumbled about sumciently and because the clothes
were subjected to no substantial scrubbing action.
During the clothes washing operation also, the
clothes had a tendency to remain substantially
dormant, especiallyif the vat were well filled with
clothes, so- that new clothes surfaces were not being
constantly presented to the scrubbing action of the
agitator. ‘Consequentlm the clothes were neither
scrubbed sufflciently nor uniformly. Almost total
reliance for thorough cleansing of the clothes was
placed on the agitation of the cleansing ñuid
20 which has been found to be'inadequate.4 -
-.An object oi my invention is to provide a novel

nate form in which the agitator may be made.
In my invention, I provide a novel method and
means for washing clothes whereby` the clothes l5
are cleansed by the passage of cleansing iiuid
through them, the cleansing ñuid being caused
to flow in powerful well-defined currents, first
in one direction, and then in the opposite direc- `
tion whereby the cleansing fluid iscaused to pass ,g o
completely through and around the clothes'. Fur
