41 Claims.

This invention has reference to washing machines, and it has for its principal object to improve the dolly or agitating means, whereby to produce a more effective and improved washing action on the articles deposited in the tub or container thereof.

The invention hasfor a further object to provide a dolly or agitating member operative from and by means of a shaft passing up through the bottom of the tub or container, and so constructed with radially arranged fins or bafile members and an intermediate surface inclined or curved upwardly from its peripheral edge, that the resultant action of the dolly or agitator,, as it is oscillated is to cause the articles being washed to be moved toward the-center of the dolly or agitating member and upwardly and thence outwardly and downwardly; or in other words impart to such articles a slow whirl like motion radially of the dolly or agitator and thereby more effectively cleanse the articles, by constant agitation and the forcing of air and water through the articles.

A further object of the invention is to provide in a washing machine, an oscillatory dolly or agitator so constructed, that it will act upon the articles being washed in a way as to cause said articles to circulate or whirl slowly in a direction radially of the tub and from and toward the center of the tub with a limited circular movement circumferentially of the tub; the centrifugal action set up by the oscillation of the dolly or agitator tends, or causes the articles as they rise to or above the water line, to recede from the center of the tub, thereby aiding in the radial circulation of such articles.

A further object of the invention is a shroud arranged on the bottom wall of the tub or container to prevent the articles being washed from getting under the dolly or agitator as it is oscillated and thereby tear or otherwise damage such articles; the surface of said shroud being preferably inclined upwardly, corresponding somewhat to the surface of the dolly or agitator between its fins or bafiies to aid in directing the articles upwardly and toward the center of the dolly or agitator. Such a construction of dolly or agitator and shroud makes it possible to proride a tub or --container with a comparatively larger surface area than is ordinarily found in washing machines of this character, and making it further possible to locate the dolly :or agitator with its fins or bafiles'above the bottom wall of the tub and closer to the normal water line in which the articles are suspended, nd thereby apply a more constant action of the dolly or agitator on the articles.

A still further object of the invention resides in the mounting for the dolly or agitator, whereby it is removable; to the manner of holding the 5 shroud in position on the bottom wall of the tub or container and to the means for imparting oscillatory movement to said dolly or agitator.

That the invention may be more fully understood, reference is had to the accompanying l drawings forming a part of the present description, illustrating a preferred embodiment of the invention, in which:-

Figure l is an elevation, in section, showing a washing machine embodying my invention;

Figure 2 is a top plan view;

Figure 3 is a plan view, partly in section, as the same would appear on the line 3-3, Figure 1;

Figure 4 is a detail plan in section, as the same would appear on the line 4-4, Figure 1, and

Figure 5 is an enlarged detail sectional view of -a part of the dolly or container and shroud, showing how the peripheral edge of said dolly or shroud is protected against articles getting thereunder.

Like characters of reference denote correspond ing parts throughout the figures.

The tub or container l'is preferably cylindrical in shape, not unlike those in general use in machines of like character, except that it is made possible, with the use of a washing element, such as I show and describe, to provide a tub or container with a comparatively larger surface area than is ordinarily found in machines of this class. Said tub or container is supported by standards or legs 2 having the usual caster wheels 3. The bottom wall 4 of the tub, when using my improved dolly or agitator, may be substantially flat, as shown.

Extending upwardly through the bottom wall 4 of the tub is an operating shaft 5, and said shaft on its lower end has a gear wheel 6 engaged by a rack or segment gear I connected to and adapted to be oscillated back and forth by a shaft 8. Connected to said shaft 8 is a crank 9 arranged to be operated by suitable means, not shown, from any suitable source of power. The gear wheel 6 and the rack or segment gear I may be encased in any suitable housing H1.

The shaft 5 extends up through and has bearing in an enclosing stem or sleeve l I, open at its upper end and to the upper end of said shaft 5 is connected a coupling member 12 having a depending flange l3 encircling the upper end of the stem or casing H and the extended axial portion of 66 said member I2 is preferably square, as at I 4, to provide a convenient mode of attaching the dolly or agitator, to be described, thereto, and to detach the same therefrom. The lower end of said stem or casing I I passes through the bottom wall 4 of the tub or container, and any suitable means is employed to seal the connection between said stem or casing and said bottom wall to prevent leakage around said stem or casing.

The dolly or agitator is designated I5 and comprises a preferably annular base portion I6 and an upstanding preferably tapered tubular sleeve-like portion or post I1 with a shouldered throat I8 having a square opening arranged axially therein to fit over the squared extension of the coupling member I2 connected to the shaft 5. Such a construction provides a simple means by which the dolly or agitator may be attached to and detached from the shaft 5, the upper end of the casing II constituting a bearing for the dolly. A bearing is provided for the bottom of the dolly with said casing I I by means of a member I5-a, forming a part of or being attached to the body of the dolly, see Figs. 1 and5. The peripheraledge of the base portion I6 of the dolly or agitator is formed or provided, preferably with a bead I9 and from such peripheral edge the upper exposed face of the dolly or agitator slopes inwardly and upwardly, as at 2| merging into the sleeve-like portion or post I1, forming in effect a central cone-like structure and correspondingly providing a sweeping surface extending from said edge portion upwardly and inwardly to the post portion I1. Also formed or provided on the base I6 are a plurality of radially arranged, upstanding major agitator vanes, fins or baffles 22 which, as shown, extend inwardly from the peripheral edge of said dolly or agitator and merge or fade into the sleeve-like portion I1. These major fins or bafiles, have their outer edges 23 preferably inclined slightly upwardly and inwardly and are formed with upper curved or arcuate ends 24 and then downwardly'and inwardly toward the center of the dolly or agitator and then merge or fade into the sleeve-like portion I1. Arranged intermediately of certain of said major fins or bafiles and disposed radially diametrically of each other, are a pair of supplemental agitator vanes, fins or baffles 20 having their upper ends preferably in a horizontal plane above the highest points of said fins or bafiles 22 and their lower portions merging or fading into the curved surface of the base portion. Such supplemental fins or baflies extend longitudinally of the sleeve-like portion I1 and project a short distance therefrom and in operation tend to force the articles being washed outwardly, whereas the combined action of the curved surface of the dolly or agitator and fins or baflles 22 is to draw the articles inwardly and upwardly of the dolly or agitator. Combined with these notions is the centrifugal force set up by the oscillation of the dolly or agitator, which tends or causes the articles as they rise to or above the water line, to recede from the center of the tub,-thereby aiding in the radial circulation of such articles. Furthermore, it is to be understood that with thisslow whirling or radial circulation of the articles there is less chance of the articles becoming entangled and there is only a limited circular movement of the articles circumferentially of .the tub and the articles thereby kept from being wound around the center stem orpost of said dolly or agitator, as will be found in many of the different machines of this class.

As will be seen, the height to which the shaft 5 extends up into the tub or container I and the length or height of the dolly or agitator I6 which is carried thereby, inasmuch as it is supported from the upper end of said shaft, will determine the position of the fins or baffles in the water in the tub, or container, and the relative positions of such fins or bafiles to the normal water line in the tub; also the position of the base of the dolly or agitator to the bottom wall of the tub. The post or stem connection formed between the shaft 5 and the dolly or agitator is such, that the upper end thereof is sufliciently far' above the water, when agitated, to prevent leakage through the top of said stem. I

Surrounding the lower base portion of said dolly or agitator is a shroud or guard 25, of preferably cast aluminum or the like. Said -shroud preferably rests on the bottom wall of the tub or container and is also preferably held in fixed position by webs 26 having a central hub slipped down over the stem or casing II with a snug fit thereon, or brazed or soldered thereto, or otherwise suitably and conveniently held. The shroud is so located as to leave an annular exposed surface of the bottom of the tub beyond the shroud and cooperating therewith. This shroud has the form of an annular ring, as shown, with an in wardly and upwardly inclined surface wall 21. When the shroud and dolly or agitator are assembled, the upper edge of the shroud lies preferably above the lowermost base line of the dolly or agitator and preferably in, the same horizontal plane with the lowermost upper surface of the base of said dolly or agitator. The relation these parts bear to each other is best seen, in detail, in Figure 5. and illustrates the practical impossibility of articles, being washed, getting under the edge of the dolly or agitator and being damaged, and further illustrates, in connection with Figure 1 the position in which it is possible to elevate the dolly or agitator, in its relation to the bottom wall of the tub and the relation of the fins or baflles' to the normal water line. As the dolly or agitator is oscillated the articles are moved upwardly and inwardly and outwardly and downwardly, being given a slow whirl like action in a direction radially of the. tub from and toward the v center of said tub, with a limited circular movement circumferentially of the tub, tumbling the articles over each other, changing their positions and effectively forcing air and water therethrough. It is well understood that the rubbing together of the articles intensifies the cleansing, and this is accentuated by those parts of the articles coming together at or above the water line. By my improved washing action, produced by the peculiar arrangement and construction of the dolly or agitator, the articles are constantly being projected to or above the water line and caused to tumble and rub against each other and thereby the cleansing made more effective.

In Figure 1 I have illustrated the normal water line and the relation of the bafiles of the dolly or agitator thereto and I have also shown by arrows the approximate movement of the articles in a radial direction toward and from the axis of the tub.

Summarizing, I have provided a new and improved method of washing clothes and other articles by means of an oscillating dolly wherein the clothes and other articles are drawn inwardly along the bottom of the tub and on to the dolly and are positively forced upwardly'from the surface of the dolly along theaxis thereof (which is located in the central washing zone) to and above the normal water level in the tub; the clothes and other articles then being forced outwardly toward the sides of the tub and downwardly to the bottom. This action is secured by providing the dolly with baflle members, the effective operative surface areas of which are higher nearer the axis of the dolly than at the periphery thereof and by arranging the surface of the dolly with an incline extending upwardly well above the periphery of the dolly and at least to the top of the baflle members. Bringing the clothes and other articles inwardly to the center of the tub and forcing them upwardly causes a bunching of such articles at the center of the tub which further causes a squeezing and rubbing of the articles together aided by the oscillatory action of the dolly. This squeezing and rubbing action varies as the articles are moved outwardly until the articles are liberated in the water at the sides of the tub. The foregoing described action occurs when the washing machine contains a normal operating load; that is to say, the washing machine industry has come to recognize that too few clothes in a body of liquid are not properly cleansed and likewise too many clothes in a body of liquid are not properly cleansed, except possibly after long and excessive running of the machine. Accordingly there is a recognized proportion of clothes and water for proper and effective washing in a reasonable time and the action I have described above occurs when that proportion of water and clothes is used.

37..In a washing machine, a tub, and a dolly therein formed and adapted to wash clothes or fabric articles, comprising a body portion the exposed face of which flares downwardly and outwardly from a relatively elevated point to a relatively low marginal edge portion, upwardly extending agitating means on said base'portion, said base portion being provided with a part projecting below said flaring base portion, and the bottom of the tub being provided with means relatively low marginal edge portion, upwardly extending agitating means on said base portion, said base portion being. provided with a part proiecting below said flaring base portion, and the bottom of the tub being provided with means correlated to said projecting portion to exclude articles from beneath the dolly, the dolly having a central post of substantial length extending upwardly to a relatively high point in the tub and beyond the operating areaof said agitating means tangling of the articles in the zone centrally above the dolly and correspondingly centrally of the tub, in combination with a drive shaft, .a sleeve through which the drive shaft passes, a bearing between the sleeve and the shaftadiacent the upper end of the sleeve,

part projecting below said of the tub' the dolly having and a bearing between the sleeve and the dolly adjacent the lower end of the sleeve 39. A dolly formed and adapted for machines for washing clothes or fabric articles comprising a base portion the upper exposed face of which flares downwardly and outwardly from a relatively elevated central marginal edge portion to provide a radially disposed sweeping surface extending inwardly and upwardly substantially from said edge portion to said central point, and said base portion being provided with agitating means projecting upwardly from the base portion, said base portion point to a relatively low.

having a high center post projecting upwardly therefrom adapted to prevent tangling of the articles in the zone centrally above said base portion; and means enabling said base portion'and its post to be operatively associated whereby to be actuated by a drive projectingupwardly from the bottom of a tub,

40 In a washing machine, a tub, a dolly adapted to be oscillated above the bottom of the tub and having a surface upwardly inclined toward its axis, an operating shaft extending upwardly through the bottom of the tub and having a driving connection with the dolly, a casing surrounding the shaft, a member cooperating with the peripheral edge of the dolly to prevent articles from getting under the; dolly, said member having a'circumferential surface upwardly inclined to-' ward the axis of the dolly and outwardly and downwardly to the bottom of the tub and having means engaging concentric with said dolly.

41. In a washing machine, a tub, a dolly supported within the tub and having an upwardly and inwardly sloping surface leading from the marginal edge of the dolly, means to oscillate said dolly alternately in opposite directions, said dolly having agitating means, said agitating means and said sloping surface being correlated to cause articles in the tub to move in a substantially radial direction outwardly away from the axis of the dolly at and above the normal water level in the tub downwardly toward the sloping surface thereof and thence upwardly over the sloping surface axially of the dolly.
