L ike characters of reference denote corresponding p arts throughout the ligures.

In the drawings 1 designates a tub, prei'- erably of cylindrical shape, having the substantially fiat bottom 2 and supported by legs or standards 3. The bottom has a centrally located opening 4 through which rojects, the preferably oscillatory sha t 5 which extends some distance up into the tub, as shown. `A bearing 6 is provided for the lower end of said shaft, beneath .the tub,

which forms a part of or is connected to a stitfening member or bracing 7 connected, respectively, to the legs or standards 3. bearing 8 for the shaft 5 within the tub,

comprises an upstanding gland or post, be-

ing tubular for a greater part of its length and having upper and lower journal por tions 9 and 10. The lower end of said gland or post is flanged and secured to the bottom of the tub by the same securing means for attaching the stiil'eiier 7 thereto and between the lower end `of the gland or post and bottom of the tub and surrounding` the shaft 5 is a packing 11. Any suitable operating means may be employed to impart, preferably, alternate oscillatory movement to the shaft 5 and for convenience I have shown a the dolly from (the of said shaft which may be coupled in any suitable manner, to mechanism not shown arrangedv for operation from a suitable motor or source of power not shown. To the upper end of the shaft 5, projecting above the gland or post 8, there is connected a clutch member 13 having a diametrically arranged slot 14 in its upper face. This member is preferably of a diameter equal to the upper end of the gland or post 8.

The dolly includes, preferably', twoseparable elements, the major dolly member 15 and the auxiliary member 16; The member 15 includes a substantially 'annular plate 17 having a` beadedY edge 18. The central portion of said member is formed into or provided with an upstanding tubular sleeve 19 to embrace the gland 0r post 8 and extend above the upper end -thereof and also prefgrably the clutch .member 13 connected to the shaft 5. Secured withiny the projecting upper end of said sleeve .19 is a clutch member 20 having a depending rib 21 artive position.

ranged for coacting relation in the slot 14 L of theclutch member 13, and 22 is a bushing arranged to snugly embrace the clutch member 13 when the member 15 is in operaplate 17, immediately surrounding the sleeve `19 is of skeleton formation to provide enlarged openings 23, and said plate at diametrically opposite points is provided with a plurality of radially arranged baille portions 24. This arrangement is such that the bafflesvextend inwardly from the edge of the plate 17 and terminate short of the center of saidplate and sleeve 19 and the plate between said baflies is imperforate or provided with perforations 25. The side walls of each baiiie 24, vas shown, converge upwardly and are curved inwardly or concave, and the upper surfaces thereof slopev downwardly and inwardly from the edge of the plate 17 to the inner ends of said baffles. This formation of the baflles, lbeing raised above the imperforate surface therebetween and having, the peculiar surfaces described, act to 'scoop the water toward the center and top of the t-ub and forces the clothes and other material toward the center of the tub and away from the edge of the dolly and-thereby prevents the clothes andother mater1al from getting 1under the edge of the dolly or becoming jammed between the edge of the dolly and the wall of the tub. Furthermore, the shape of the baiiies will act to lift and agitate the clothes of other materials and thereby cause complete circulation of the water.

In cross-section, the baffles 24 form pockets or compartments 26 therebeneath, which are lclosed by walls .27 at their outer ends. Such a construction, taken in connection with the imperforate portions of the plate 17 w1ll 1n The central portion of thev crank 12 connected to the extreme lower end '"vsure, when the dolly is oscillated to agitate the water above and below the plate and keep it 1n constant cirulation through the perforations in said plate.

The auxiliary member 16 of the dolly 70 includes an upstanding tubular sleeve-like portion 28 having an inturned flanged portion 29, 4at its upper end, to overlie the upper end of the sleeve 19 and a part of the clutch member 20. The lower end of said sleeve is vformed or -provided with a plurality of'diametrically disposed and radially arranged baffles 30, which, when the auxiliary member is in operative position extend to and overl1e the inner ends of the baffles 24, whereby the combined baffles 24 and 30 form' a continuation from the edge of the dolly to the central post portion 28. Furthermore, the bafv 'fles 30 being similar in shape and contour to the baffles 24 the pockets or compartments 85 26 extend substantially the full length of such combined baffles, `with the baffles 30 partially overlying the openings,Z 23 in the plate 17. e

It Wi of the auxiliary member 16v of the dolly that it is removable from the major portion ,of said dolly lby the mere lifting of said auxiliary member therefrom, and that when said auxiliary member, is deposited in posi- @5' tion, provided of course, the clutch members 13 and 20- are in clutch relation, and said shaft 5 is oscillated, corresponding loscillatoryy movement will be imparted to the dolly l By removing the auxiliary member 16 from the major-member 15, the tub may be flushed by pouring'water therein, which will pass beneath the major member 15 through the openings 23 and 25 therein. Ak` l drain 31 is provided, connected with the bot- 105 tom of the tub.

L have disclosed two ways in whichthe attendant or operator may connect and disconnect the clutch connection between the dolly and the source of power, in this in- .110

stance, the shaft 5. In Figure 1 a handscrew 32 is shown threaded through the clutch member 20 and the rib 21 thereof and bearing at its lower end in the slot 14of the clutch member 13. With this arrangement,

the member 20 acts as a nut, and the attendant or operator, may, byV turning the hand screw 32 lift the clutch member 20 from out of engagement with the clutch member 13 and with it the entire dolly structure. The

clutched and declutched positions being shown, respectively, in Figures 1 and 2. It is my object to apply the operating means for connecting and disconnecting the clutch means, between the dolly and the shaft, i at the point of the application of the source of power to said dolly. The means in Figure 1 accomplishes this purpose, and also the means shown in Figure 5. The latter gure, however, .disclosing a means for actuat- 7 llbe apparent from the description 9U ing the clutch parts, located, preferably without the tub, whereas the former discloses the` means located within the tub.

In Figure the shaft 5 has an axial opening 33 therethrough, which coincides with-an opening 34 in the clutch member 13 and also with an opening 3Q in the crank 12, and through these openings is reciprocally arranged a rod 36, the upper end of which normally bears against the rib 21 and when said rod is lifted will, in turn, c ause a disengagement of the clutch parts and the lifting of the dolly from operative position. Reversing the movement of either the hand screw 32 or the rod 36 will permit a reengagement of the clutch parts and the dolly moved to operative position.

The lowercJend of said rod 36 is in operative eiwagement with a bell-crank lever 37 to which is connected a link 38, and said link, in turn, connected to al crank-arm 39. To the crank-arm 39 is connected arod 40 disposed, preferably, in a vertical position on the outside of and alongside the tub and the upper end of said rod is connected with an operatorslever 41 pivoted to the side of the tub and including means, such as the yielding ball 4Q and sockets 43, of well known construction for locking the lever 41 and the rod in different positions. The lever 41 is preferably located on the tub, in a position, so that an attendant standing alongside the tub may reciprocate the rod 36, by a pull on the lever 41 rather than a push on said lever, although the lever may be actuated by 'a pull or push, as will be understood.

The drawings illustrate the/ dolly, including' the separable baffles thereof, as normally operating immediately vabove and next adjacent to the bottom of the tub, withl free access to the clothing or other materials therein and with the parts so constructed that the finest of materials may be washed without damage thereto. Furthermore, while I have shown the dolly ascovering 'substantially the entire area of the bottom of the tub, it could be of less diameter due to the shape or contour of the baffles which tend to force the clothes and other materials towards the center and upward in the tub, thus preventing the same from getting under the dolly Vhat I claim is 1.
