WASHING MACHINE -f Filed Nov. 16, 1933 2 Sheets-Sheet 1 E. DAVIS WASHING MACHINE Nov. 27, 1934.

Filed NOV. 16, 1935 2 Sheets-Sheet 2 A m i Patented Nov. 27, 1934 UNITED STATES PATENT OFFICE My invention relates to improvements in washing machines and the main object is to provide a machine including cooperating agitator and tub of novel form and shape designed to wash clothes quickly and efficiently without tangling or tearing the most delicate fabrics.

Another object is to provide in a washer of this kind an improved form of agitator including a radially ribbed or corrugated head plate, a knobl0 like centrally located head on the underside of the head plate, and depended radially extended wings on the head plate and head, the said wings being rounded and ared outwardly to form lobes at their outer ends.

A further object is to provide in combination with an agitator as above a complementarily formed tub in which the lower peripheral margin thereof is built up and brought adjacent the lobes of the agitator wings to enhance their agitating and washing action on the clothes in the tub.

With the foregoing and other objects in view the invention resides in the novel construction and arrangement of parts as hereinafter fully set forth and claimed, reference being had to the accompanying drawings wherein:

Figure 1 is a vertical cross section through a washer tub constructed in accordance with my invention and provided with my improved agitator.

Figure 2 is a horizontal section along the line 2--2 in Figure 1.

Figure 3 is a vertical cross section through a modified form of tub, the agitator not being shown in this view.

Figure 4 is an inverted plan view of my improved agitator.

Figure 5 is a section along the line 5-5 in Figure 1.

Referring now with more particularity to the drawings the reference character A designates a washer tub having a removable hinged top B through 'which is centrally journaled an agitator shaft C adapted to be rotated by a gear D and rack E. The foregoing parts are all conventional in their construction, arrangement and operation and no invention therefor is claimed herein. Preferably the agitator shaft C is provided with a ball bearing race 6 where it passes through the tub top B instead of the plain bearing usually employed.

My improved form of agitator, rotor or dolly is designated generally at 7 and comprises a large circular head plate 8 provided on its intended upper side with a centrally located hub 9 adapted to be rigidly secured as by a set screw 10 to the lower end of the agitator` shaft C to be rotated thereby and supported in a horizontal plane slightly below said tub top B. A large rounded knob-like head 11 is formed or secured centrally on the underside of the head plate 8 and tapers downwardly and peripherally to its rounded lower end 12 as shown. Four, moregor less, equally spaced and radially extended vanes br wings 13 are then extended from this head 11 outward on and at right angles to the lower face of the head plate, said wings first tapering in vertical width or height adjacent the head as at 14 and being then widened to form rounded lobes 15 adjacent their outer ends. Preferably the head plate 8, head 11 and vanes 13 are all cast integrally of some rustless and stainless material such as aluminum but any other form of construction or material may be employed as desired. Between the vanes 13 the under side of the head plate 8 is provided with radially extended grooves forming radial ribs or corrugations 16 and in similar 75 manner the sides of the head l1 are grooved and ribbed or ridged as shown at 17. The vanes 13 are relatively thin through their greater part as shown in Figure 5 but have their margins rolled, beaded or thickened as designated at 18 for 80 strengthening purposes as well as to enhance their washing action and engagement with the clothes in the tub A.

In the ordinary tub there is a tendency for the clothes to work down in the corner F formed at the peripheral junction between the lower ends of the tub at the bottom G. In order to prevent this disadvantageous action and to bring the clothes nearer to thelobes 15 of .the vanes 13 I provide an annular, inwardly and downwardly sloping false bottom 19 around the margin of the tub and made up of 'a number of tapered, tongue and grooved boards 20 secured at their outer ends at 21 to the tub sides above its bottom G and extended inwardly and downwardly to the said bottom and secured thereto by their inner ends -as at 22. I'he bottom of the tub is thus dish or cup shaped as shown and it will be the downwardly and outwardly 4ex hanging formation of the vane lobes 16 brings 100 them into relatively close juxtaposition with the bottom of the tub and resuts in a substantially even space between the tub and agitatorzboth beneath and around the agitator. To this end the oted that nding or lower end 12 of the head 11 drops somewhat below 105 the level of the vane lobes 13 resulting in a somewhat tapered or conical shape of the agitator substantially complemental to the bottom of the tub as provided with the sloping false bottom 19.

The agitator isy rotated in usual manner and no gyrates and agitates the clothes and water in the tub to rid' the clothes of dirt. In addition to this normal and substantially conventional action the corrugations or ribs 16 and 17 on the head plate 8 and head 11 rub the clothes free of dirt. The cooperating near relationship formed between the vane lobes 15 and false bottom 19 as described prevents the clothes from working down into the corner F and becoming rolled, tangled and torn therein and this juxtaposition between the lobes and bottom thus results in the clothes being carried continuously around in the tub and washed quickly and efficiently without tearing or tangling. One of the boards 20 making up the false bottom 19 may have a drain opening 23 through which the water may be drained out through the usual tub drain H.

It will be noted that a conventional form of washer may be readily improved and equipped with my invention simply by replacing the usual dolly (not shown) with my improved agitator 7 and then mounting or placing the false bottom 19 in the tub. Where the form of false bottom 19 made up of the boards Z0 would be in any way undesirable a separate cup or dish shaped metal'false tub as designated at 24 in Figure 3 may be set down into the washer tub A and secured theretoaround its upper edge 25 by screws or nails 26. A suitable drain and plug are provided in the false tub as at 27. This false tub 24 has rounded shallow corners or bottom as at 28 and brings the clothes into proper` and desired engagement with the agitator in the manner desired. The agitator 'l and its shaft C may be either hand or power driven and the shaft may extend either through the top as shown or upward through the bottom (not shown) It is thought that further details of the utility and advantages of my invention will be understood without further description herein and while I have set forth certain preferred members and methods of assembling and constructing the elements of my invention it is understood that I may vary from the same in minor details so as best to construct a practical device for the purposes intended, not departing from the spirit of the invention and Within the scope of the appended claim.

I claim:

In a washer agitator, a circular head plate, a centrally d'sposed and depended rounded head on the head plate, a plurality of radially disposed vanes on the underside of the head plate extending from the head outward, the said vanes having widened rounded lobes adjacent their outer ends, and the said head plate and head having radial spaced ribs between each pair of the vanes.
