As shown in Figs. 1,,and 2, stem 25 is of tubular forin,-and slidable therein is rod 33 having head 34 at its To all whom it may concern:

Be it known that I, JOHN C. FORSTER, a resident of Pittsburg,in the county of Allegheny and State of enns lvania, have invented certain new and use 111 Improvements in lVashing-Machines, of which. the following is a specification.

e general object of this invention is to to in ury.

Fig 3 a bottom plan of in preferred ca 35 and incloses spring 36, which latter and the pounder normally depressed. This spring permits the pounder to yield upwardly on its down stroke, thereby insuring efiective pressure on the clothes without danger of breaking its operating parts. The rod 33 fits at its lower end in a vertical sleeve 37 secured to pounder head 26, and is locked thereon by two clutches, each conslsting of a lever 39 pivoted to sleeve 37 and t e accompanying tion on an enlarged scale of the upper portionofthe pounder, taken on line H of Fig. 5 a view similar to Fi 2, illusmodified construction 0 pounder hod of attachment to the carrying member.

Referring to the drawings, 2 is the tub, he supporting legs of any suitable height. The tub 2 is provided with a slightly conical bottom v4 into which is the drain pipe 5, rovided with a stop-cock 6. An inner tub-like carrier 7 bottom and, sides at 8, is within tub 2 upon a central pivotal support 9, and'a series of rollers 10.

-To prevent the formation of a partial vacuum in the pounder which would tend to the combinaa horizontal hold the articles therein on 'theup stroke, bearin supported above the container, perforations 47 are formed in top which gui'de arms projected from the bearing, a are controlled by disk valve 48, normally vertically movable pounder having an .op-

Tub 2 may beprovided with a cover 52, slotted at 53 to permit of'its being readily slipped into place and removed when the ounder is in position. If desired a wringer trough or box 54 may be secured to one side of the tub and provided with openings 55 to drain it into the tub.

In the construction shown in Fig. 5, the pounder carrying sleeve 37 is made somewhat longer than sleeve 37, Fig. 2, and is provided with a screw. cap 56, through which passes a short stem 57 provided at itslower end with a head 58. A spring 36 said head and the hold the latter norsimilarly to Fig. 2. A conical cap 59 incloses valve stem 49' and excludes water from the spring-inclosing sleeve.
