'WASHING CHINE.

pplicaton ledll'uly 22, 1925. Serial No. 45,283.

My invention relates to washing machines and more particularly to improvements in lwashing machines of the dolly type.

The usual types of washing machines are s Classifiable according to the relative action of the dolly upon the fabrics and upon the liquid, respectively. In the rst class, ma-

chines having a peg type of dolly effect merely a swirlin movement of fabric io through the liquid, resulting 1n excessive strain and wear in `the cloth being washed. ln the second class, the result is effected primarily by agitation of the liquid. Familiar examples of this class are found in i the vacuum cup machines, and in those utilzing the capillary eifects common to 'the old fashioned scrubbing board. A third class of machine combines the. operations of the preceding types. The cylinder ma- 2o chines, which lift the fabrics and ldrop them back into the liquid, are good examples of this third or combination class. lt is evident that each of these type is peculiarly adapted to thev most eiiicient washing of only certain restricted classes of materials.

The object of my invention is to provide agitating means which comprises a novel form of removable, invertible agitator and which may be adjusted in its position with A respect to the materials to be washed, thereby providing in one machine, means for washing most efficiently any type of fabric.

Another object is to provide an agitator with its drive and mounting which cannot,

tear the clothbeing washed.

Further objects and advanta es of my invention will appear from the rawings and description thereof as hereinafter set forth.

Although my invention consists lar ely in the construction and arrangement o parts hereinafter described and particularly pointed out in the claims, yet I do not limitvmy invention to the precise form or construction of parts shown or the several parts thereof, inasmuch as various alterations may be made without changing the scope of my invention. In the drawing, Fig. 1 represents a top view of the operating dolly of the washing machine: Figs. 2, 3, and 4 show the doll in various operative ositions.

Referring y numerals to the drawings, the tub-base 10 preferably rests upon a substructure made of angle bar or other suitable material. The tub is preferably composed of a heavy sheet metal body 11 which -may be of'any desirable ,shape and which is preferably provided with 'an inwardly extending turned-over upper edge 11 and a flange 10 on its lower edge. Tub body 11 with its turned over edge 11,l and flange 10 e0 may be readily formed from a iiat sheet of material, thereby providing ease and economy in manufacture. Tub base 10, which may be die formed, ispreferably united vto the inside surface of flange 10 by a welded e5 or other joint in such. a manner that the inside surface of the tub structure presents no ragged edges, seains or projections. This inside surface is preferably tinned or other- Wise coated, a'ording a rust proof surface, 7o thus permittingthe use of steel orother comparatively rigid material in the tub construction, and which coating material willv further provide a means of filling any interystice which may exist at the tub joints. By I the use of this type of joint, the gaugevof the sheet metal is not limited as in the usual constructions using double seam joints, orfin the case of forming the tub by spinning or other methods. Preferably integral with the so base 10 is the agitator Well or pedestal 13'v whichinay be attached in any suitable inanner and is preferablyv centrally situated therein. Connection with'the driving mechanism is preferably effected through Well 13 85 *l by means of an agitator sleeve 14. This lat-v ter is preferably rotatably mounted on the stationary agitator Well or pedestal 13 and rotates on bearings 15 and 16 which may be' of any suitable type. The sleeve 14 prefer- 90 ably extends the full length of its support to the bottom ofthe tub so that in rotation there is no tendency for the clothes to tear because of relative movement between the sleeve and well. The lower end 14 of the 95 sleeve 14 is preferably fiared to divert fabrics from the center to' the sides of the tub andtlius provides a natural course of movement of both clothes and water. rlhe agitator 17 is preferably mounted on agitator sleeve 14 100 and in such a mannerias to be driven by it and to be easily lifted from the sleeve to permit inversion of position of the agitator and its removal Whenever necessary. The agitator 17 preferably consists of a disc- 105 like structure, an approved form of which is shown in the drawings. 18 represents a preferable forni of relatively thin blades on one operating surface or face of the agitator and 19 represents a preferable forni R10 of relatively angular projections on theV reverse surface.

When large Aheavy fabrics are to be washed, the blades l18 are preferably placed upon the top of the. material, giving agitation of both cloth and liquid.' If hea small piece fabrics are in themachine, t e agitator yis lifter from the sleeve A and replaced with its reverse projections 19 Y above the bottom as will be determined by4 respectively, the agitator being supported downward, providing only -a slight move- `ment of materials suliicient to change their the nature and amount of material to be washed. If the agitator be left in the bottom of the receptacle with its blades 18 up"-v ward and thematerials immersed labove, it,

only liquid agitation results. This latter arrangement is best suited to light delicate' fabrics. The three suggested ositions of the agitator 17 with respect to t e materials to be washed are shown in Figs. 2, 3 and 4- above the bottom of the tub, in certain cases, by the materials being washed. In Figs. 3 and 4 the agitator is shown in the posltion which it would occupy when resting upon the material to be washed. Other combina- A tions of agitator design and position may be par'al el to or at right angles to each other, 40

' type of clutch used.

While I show the projections and blades on the agitator surfaces as being at approximatel right angles to these surfaces, and

the angle between said blades and said surfaces, or between different blades, may be varied in any way. Further these projections or blades may beveither flat orl cambered. Holes 20 are perferably provided in the agitator to produce a better circulation and agitation o liquid, and to permit passage of the liquid through the agitator.

The agitator 17 and sleeve 14 are preferably given an oscillating movement by means of shaft 21, preferably to the upper end 'of which sleeve 14 is secured by a pin' 36, or by a nut or other means. Below the tub on shaft 21 is preferably fitted some suitable (not shown) actuated by a clutch control, preferably permitting the engagement or disengagement of a. pinion with a rack' of suitable type bythe reciprocation of which the shaft is given an oscilating movement. l
