contents of the tank.

It will be apparent that the construction shown serves as a check for the operator when introducing the wash-water in the rst instance, tending to prevent an improperly high water level and that in the preferred form, which includes an upfiow pipe such as 19, after the washing has been done it enables the dirty water settling at the bottom to be easily removed and substituted by fresh water, such as may be used for rinsing as above pointed out, and also that it keeps the level from rising so high as to impair the subsequent use of the machine. When the tank is to be completely evacuated the stopper rod is pulled up, which in the present case, also lifts the overfiow pipe but it will be understood that the overfiow and level maintaining effect is quite independent of the stopper and the latter could if desired be independently located, the overflow such case being fixed. The concentric arrangement of the upflow and downflow pipe is preferred because of compactness and economy of manufacture but the principle will be seen to be capable of incorporation in other and different forms all of which are intended to be covered by the following claims.

Claims:

l. The combination in a washing machine vhaving a tank, clothes washing mechanism within the tank and a motor for driving said mechanism, of a pump also driven by said motor, an overflow pipe communicating at its lower end with and the removal by the pipe in 4 the suction side of the l pump and extending upwardly into the tank to establish a constantlevel therein, a second pipe within the tankcommunicating with the upper end of the first and terminating at'its lower end adjacent-the tank bottom to limit the flow through said overflow pipe to liquid drawn from the lower portion of the tank, and vent means operative to prevent the siphoning action of said pipes pump, through the overflow pipe, of the entire liquid contentl of the tank. v

2. In a household washing machine, the Icombination'of a Wash water tank, a motor, clothes Washing mechanism within the tankv driven by said motor, and means for con trolling the wash wat-er comprising a pump, also driven by the motor, having a delivery pipe adapted to discharge Wash water toa higher level, and a suction pipe for said pump having two intake openings within said tank, one of said intakes being at the bottom of the tank and normally closed during washing and the other being an overflowpassage aving its entrance 4slightly above the bottom of the tank and adapted to establish a predetermined water level therein above the level of said entrance and means `for preventing siphoning of the wash water through said overflow passage, whereby continued operation of said pump evacuates said wash water from the lower part of the tank and only to said predetermined level unless said first mentioned pump intake is opened. y

In testimony whereof, I have signed this specification.
