To all 'whov n it may 3 7 Be it known that I, SAMUEL'DQBSEY GRIP? FITH, a citizen of the United States, residi at Curwensville', in the-count of Clearfiel a and State of Pennsylvania,

certainfnew and useful Im rovements in' Atmospheric Clothes Poun ers; and I do "hereby declare the followin elear, and exact description 0 the invention, will enable others skilled in the art to .wliichljt appertains to make and use the l or washing clothes by a oundinfiaand atmospheric operation in whic a cup-s ped plunger is employedhavi a disk-valve depending from a perforate partition in the cup for controlling the inlet of the air therein at each upwardmovement of the cu it is found that while the disk valve is e ective for-closing the inlet of the'air and to cause the-air in the cup to be forced through the clothes by the pounding action, the diskvalve'is liable to be uncertain in its 0 ening function to allow the cup to be-filled with air. My 'im rovement is directed to means objection is overcome and the disk-v Va is rendered certain in its opening function; and: also by which the. valve is caused to have an active pounding and agitati'nfimfunction upon the clothes, the valve t purpose being provided with one or depending plates movable with it and c aims appended hereto I will set out arts and combination of parts wherein my improvement resides in'connection with the accompanying drawings, wherein- Figure 1 shows-in vertical section an athaving my improvement, the air controllin ing in open position. Fig. 2 is an i eiitical air controlling valve being in closed position. Fi 3 is a' bottom view of the cup-pounder. ig. 4 is a bottom view of the plate-valve having oval formed depending plates. I v

' bi i t e ac valve depending plates is tube 5, w 'ch extends 'to and is fixed to the cupl-partitionpins 7 and has a diameter adapted to inclose the openings in the partition and is movable preferably with its suspending pins for opening and closing the openings in the cup partition to admit air into the cup as it is-raised and to cause the air to be forced into and through the clothes as the cupis driven upon them. Forthis purpose the valve suspending pins preferab y pass t partition and the o ning movement of the valve is limited by t e heads of the pins resting, upon the partition. Appended to and depending from this plate-valve is one or more plates 8, 8, of less area than the valve, one below the other and preferably the lower ones of decreasing area, each suspended from and movable together with the yalve. That is to say, the depending lates may each have a-fixed relation to the va ve and to each other cup-chamber from the partition by headed hrough holes inthe by their suspending pins 9, 9. These'deplates may be of any suitable form preferably havingcurved edges so as not to in ure the clothes. They may be of oval form crossing each other at ri ht angles, but of-whatever form they each ave a separate pounding action upon the clothes and.a separate suction action thereon in the lifting movements of the cup, and in this way the action of each plate reinforces the pounding function of the cup and-facilitates the washin and cleansing o ration of the clothes. ese valve depen ing plates have also a releasing function for the plate-valve, that is, they render it certain by a pulling action on the valve, caused byt e water to olpfinit on the lifting movement of the cup.

's s important because the flat sealing surface of the valve would be liable to adhere, of the euptendency o artition; and, to counteract the the valve to stick, each of its in its lifting action on the water, caused y the water to have a pulling function aidedby their wei ht, upon the plate-valve, so that it is cause to open at evegrlift of the cup to insure a full supply of ail} "oughthe cylinder into the cup to be forced through the lates-I prefer to mg a better To give firmness and strength to the handle supporting socket it is braced at its connection with the partition by a conical stay 10, which has openings'll, for the p of air through the cylinder to the cup.
