5 Claims. (Cl. 68-22) The present invention is directed to an improved washing machine assembly and, more particularly, an improved detachable cover assembly for washing machines having self-contained wringer assemblies.

The washing machine assembly of the present invention provides a cover member positionable over the wringer assembly of the machine to cover and conceal the wringer and close off the washing machine tub. Means are also provided on the casing of the washing machine whereby a cover may be detachably connected to the casing to function as an article receiving tray for receiving articles discharged from the wringer.

An object of the present invention is to provide a washing machine assembly with a detachable cover which also serves as a clothes hamper for receiving clothes discharged from the wringer mechanism.

Another object of the invention is to provide a detachable cover assembly for a washing machine which is invertable to form a tray arranged to be detachably secured to the casing of the washing machine.

The novel features which I believe to be characteristic of my invention are set forth with particularity in the appended claims. My invention, itself, however, both as v ing description taken in conjunction with the accompanying drawings in which:

Figure 1 is a view in elevation, and partly in crosssection, of a washing machine embodying the improved cover of the present invention; and

Figure 2 is a fragmentary view, with parts in elevation, illustrating the manner in which the cover of the washing machine may be removed and re-attached to the casing to form a hamper for receiving wash from the wringer assembly.

In Figure 1, reference numeral 10 indicates generally a washing machine including a generally rectangular cabinet 11, which is provided at its base with a plurality of non-swiveling casters 12 spacing the machine from the supporting floor.

The top of the cabinet 11 is formed with an inwardly extending flange portion 11a, the latter serving to bottom a resilient retaining ring 13. Disposed above the retaining ring 13 is a hollow cover member 14 which has an inwardly turned flange portion 14a resting on the retaining ring 13 when the cover 14 is disposed in a position in which it encloses a wringer mechanism generally indicated at numeral 15 in the drawings.

The resilient retaining ring 13 also receives

flange portions

16a and 17a of a shelf-like flange 16 and a tub 17, respectively, the

marginal edges

16a and 17a being secured together by welding or other suitable means. The flange 16 is shown as having a plate 16b secured thereto open at its center, and having a downwardly and inwardly turned edge 16c forming a smooth clothes receiving opening for the tub 17.

As best illustrated in Figure 1, the tub 17 is generally Patented Sept. 22, 1959 rectangular and is provided with an upwardly sloping base portion 17b. A vertically extending boss or center post 18 is secured to the base 17b by a plurality of bolts or machine screws 19 whose ends are received in threaded engagement in a plurality of internally threaded spacer rods 21.

Extending through the hollow boss or center post 18 is a drive shaft 22 which is keyed or otherwise secured to an arcuately shaped impeller 23 upon whose periphery is disposed a plurality of agitator vanes 24. v

The opposite ends of the spacer rod 21 have threaded end portions along which aplurality of nuts 26 are received in threaded engagement, the nuts 26 serving to fasten a support plate 27 in spaced relation to the bottom of the tub 17.

The drive mechanism'for the agitator may include an electric motor 30 which is supported in depending relation from the supportplate 27 by means: of a plurality of suspension bolts 37. The motor 30 has an output shaft 31 to which is secured a pulley 32, with a belt 33 being provided to couple the output of the motor 30 to a pulley 34 attached to a shaft 35. A transmission system generally indicated at numeral 36 of the drawings transforms the constant rotary motion of the shaft 35 into an oscillatory motion of the agitator through any suitable mechanical means. I

The washing machine assembly illustrated also employs an improved heating element which is described and claimed more particularly in my application Serial No. 463,403, filed October 20, 1954, now Patent No. 2,826,- 905 and entitled Washing Machine. This application is a division of the aforementioned parent application Serial No. 463,403.

As seen in Figure 1, the heating unit may include a centrally apertured plate 38 which has a contour substantially complementary to the contour of the base 171;. The plate 38 is spaced from the sub-base 17b by a pair of resiliently

deformable seal rings

39 and 40 composed of a material such as a silicone rubber which has the ability to resist penetration by moisture and moisture vapor. Thus, when the

seal rings

39 and 40 are compressed between the plate 38 and thetub base 17, there is provided a substantially fluid tight space in which a pancake type heating element 41 may be located without substantial danger of an electrical arc-over occurring.

The washing machine illustrated in the drawings employs a hand operated wringer mechanism including a pair of cooperating wringer rolls 71 and 72 journalled for rotation between a pair of spaced bearing support members 73 and 74. The lower wringer roll 72 has a shaft 75 extending through the bearing support member 74 and a pivotally mounted operating crank 76 engages the shaft extension.

When the cover 14 is in the position illustrated in Figure 1, it serves as an eflective shield against dust and moisture entering the interior of the washing machine. When the machine is being operated however, the cover 14 can be employed as a hamper for receiving wash being passed through the wringer assembly 15'. Means are provided for detachably supporting the cover 14, these means taking the form of a pair of brackets 78 which are secured to an offset portion 11b of the cabinet 11. The brackets 78 are formed with outwardly extending angular bent end portions 78a and 78b at opposed ends. The upper bent end portions 78b provide upwardly opening hooks for receiving the cover 14. The lower bent end portions 78a provide inclined engaging surfaces, and each has a resilient bumper 81 arranged to engage the back of the cover 14 to prevent marring the finish of the cover 14. The cover 14 is engaged with the upper bent end portion 7812 by providing a pair of spaced slots 14b 3 through which the angularly extending portions 78b may be received. In the position illustrated by the dotted lines of Figure 2, the cover 14 is in its inverted position and thereby provides a tray-or hamper for materials being passed through the wringer assembly.

It will be evident that various modifications can be made to describe the embodiment without departing from the scope of the present invention.

I claim as my invention:
