(ci. ca_-131) My invention relates to clothes washing ma chines,- and more particularly to -a novel method . and means for washingl clothes. In washing machines of the prior art of the reciprocable agitator type, thorough cleansing of Figure 5 is a view taken on line 5--5 of Figure 3 ` in the direction indicated by the arrow. Figure 6 is a view of an alternate construction in which the agitator is rotated, as well as recip rocated. 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 _ _ . 5 Figure '7 is a view taken on line 'l-l of Figure 6. Figure 8 is _a view taken on line 8-8 of Figure _6. Figures‘9 and 10 are plan and sectional views of an alternate form of my novel agitator. Y Figures 11 and l2 show another alternate con- vi0 struction for an agitator. ' i Figures 13 and la disclose still another alter 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 method 'and means for washing clothes by which ~ ther, the clothes are eiïectively agitated and tum the aforementionedvdimculti'es are overcome and bled about so as to expose new clothes surfaces generally more thorough cleansing of the clothes 25 is secured. ' - ' notronly by the turbulent action of the cleansing iluid but also by the movementof the‘clothes- 25 ` Another object> of my invention is to providei washing means itself.

' The plate 16 is secured by nut and bolt assemblies 18 to a bracket 19 depending ' 30 from `the housing 3l. When the plunger rod is reciprocated, the movement of the pin 13 in the slot 14 will cause the plunger rod together with the agitator I4 to rotate in one direction upon the upward movement and in the opposite direc 35 tion upon the downward movement of the plunger rod. This construction will perhaps' cause a greater turbulence of the cleansing fluid, a more crank aim 43 is pivotally-secured to a pitman ' 44 at 4l and the pitman, in turn, is- pivotally con ` violent agitation of the clothes and a more thor 40 nected to an operating lever_41 at 43.
