The specification discloses an improved washing machine having an outer wash tub adapted to be filled with water to a desired predetermined level. An inner perforated washtub is mounted in a concentrically spaced relationship to said outer wash tub and is adapted to receive the clothes to be washed. A compressor unit is adapted to reciprocate from the top to the bottom of said wash tub to briefly agitate the clothes and then to squeeze the water from them from the inside out. |

DETAILED DESCRIPTION I claim: 1.
A washing machine including an outer wash tub, an inner perforated wash tub mounted concentrically in said outer wash tub, a compressor unit including a pair of compression springs mounted in said compressor unit and a main plate attached to and interposed between said compressor springs, said compressor unit being mounted to reciprocate within said inner wash tub, a compressor unit support means connected to said compressor unit, driving means connected to said compressor unit to receiprocate said compressor unit in a predetermined fashion, and means to drive said compressor unit driving means, the stroke of said main plate being variable and depending on the amount of clothes placed in said washing machine and the spring coefficient of said compression springs, said washing machine thereby adapted to briefly agitate the clothes in the washing machine and then to squeeze the water from them from the inside out.
2.
The device defined in claim 1, and having a plurality of supporting legs mounted to said outer wash tub.
3.
The device defined in claim 2, wherein said compressor unit driving means include a double acting hydraulic cylinder fixedly mounted to said supporting legs, a hydraulic pump, a plurality of hoses as required to operate the hydraulic system connected to said pump, a suitable control valve interposed between said pump and said cylinder, and a suitable driving means for said pump operatively connected thereto.
4.
The device defined in claim 3, wherein said compressor unit driving means include a pair of lower guideways mounted to said supporting legs in a 180.
degree.
opposed relationship, a pair of upper guideways mounted to said outer wash tub in 180.
degree.
opposed relationship on a common axis with said lower guideways, a pair of push rods slideably mounted within each pair of said upper and said lower guideways, a connecting channel fixedly mounted between the lower ends of said push rods to connect the same, and a bracket connecting the piston rod of said hydraulic cylinder to said channel, all adapted to reciprocate said push rods in a vertical direction, said push rods including at their upper extremity an extended short arm portion each having a circular portion thereon with a hole provided in the center thereof
