having an improved hook element for support- Hole is in the hook element is of sufficient ing the cover when not in use. size to permit distortion of the ring portion of Another object of the invention is to provide the element under manual pressure whereby top a cover of the above type having a hook element flange !3 may be projected through the cover formed entirely of rubber and which can be easily hole and assume its normal shape to overlie a.

ring shaped area of the cover bounding the hole. The bottom flange 14 will then abut a preferably larger ring shaped area of the cover whereby the hook element is firmly and detachably secured to the cover by the flanges. The aforementioned manner of mounting the hook element on the cover .is relatively quick, avoids the use of tools on the assembly line, such as riveting apparatus, and provides a sufficiently firm engagement with the cover to prevent shifting of the hook element from a :properly adjusted position. In the event it is desired to replace the hook element, this can be quickly and easily effected without the use of .tools.

Numerous rubber materials are-available which will permit the ring portion of the element to be deformed under reasonable manual pressure and at the same time prevent any substantial bending of the hook portion 16 due to the weight of the cover, although the bending tendency can be .largely controlled by providing a hook portion of suitable :cross sectional area and shape.

It will'be noted by reference to Fig. .4 that the tub is provided with a radially inwardly extending top flange forming a seating surface for the cover peripheral portion, the cover bead ll being adapted to seat in the groove of this flange. It is obviously desirable that the hook portion l6 be disposed as close to the cover edge as possible consistent with clearing the inner edge of the tub top flange when the cover is in place. In prior practice wherein a metal hook is riveted to the cover, it frequently happened that the .exposed rivet head would scratch the tub when locating the hook to engage the tub flange. It is apparent that this could not occur with my improved hook element.

The cover when supported by the hook will tend to swing towards and engage the tub at its lower portion, and particularly in the case of tubs having slightly sloping rather than vertical side walls, the ring portion of the hook element acts as a cushioning and spacing means for the cover in that the ring portion diametrically opposite the hook can engage the tub side wall.

WVhen'the cover is in place the hole l9 provided .in the ring portion will permit a finger grip on the cover or can receive the hooked end of a conyentional drain hose provided in some instances on washing machines.

I have found that a substantial saving in cost, in addition to the advantages pointed out, can be effected by employing a hook element of the type described compared to a conventional metal hook.

I wish it to be understood that I do not desire to be limited to the exact details of .construction shown and described, for obvious modifications will occur to a person skilled in the art.

What I claim is:

:l. The combination with a cover for washing machines and the like having a portion adjacent the cover edge which is provided with a hole and is adapted to be substantially horizontally disposed with the cover in operative position, of a hook element formed entirely of rubber secured to said cover portion, said element comprising a ring form portion having a peripheral groove therein forming top and bottom flanges, a hook portion extending from the bot- ..tom flange and generally .normal thereto, the

ring portion being manually deformable whereby the top flange may be projected through the cover hole permitting a ring form area of said cover portion bounding the hole to be gripped between the flanges, and the bottom flange being of sufiicient radial extent and thickness to serve as a cushioning and spacing means preventing contact between the cover and the machine tub side wall adjacent the hook element when the cover is supported by the hook portion engaging the top edge of the tub.

'2. The combination as described in claim 1 and wherein the hook portion has a toe at the end thereof, and the hook portion increases in cross sectional area from the toe towards the ring portion.

3. The combination as described in claim 1 and wherein the hook portion is sufficiently rigid to support the weight of the cover without subs'tantial bending of the hook portion.
