I 1 Claim.

This invention relates to new and useful improvements in the construction of washing,

machines, and relates more particularly to the construction of the washing vat and cover 5 therefor.

Heretofore, the common commercial practise in the manufacture of the more expensive types of domestic washing machines has been to fit the upper edge of the side walls of the tub, which contains the clothes and washing fluid, with an annular casting, usually a die casting. In order to avoid the metal to metal contact of the die casting with the upper edge of the side walls of the tub, which is very likely to chip the porcelain with which the side walls of the tub are coated, it is usual to provide the rim of the tub with an annular rubber ring and mount the die casting on the rubber ring. While this die casting perhaps serves the purpose of strengthening the rim of the tub to a minor extent, its primary purpose is to cover up the tub rim and make the upper portion of the tub more attractive as the non-ferrous metal of the die casting is adapted to take a high polish. This construction has certain marked disadvantages, the foremost of which 'is that the die casting and the assembly of it on the tub are very expensive and add. considerably to' the cost of the washing machine. In practice, this casting is shaped so that a portion thereof extends internally of the rim of the tub with, the

upper surface thereof sloping inwardly and slightly downwardly so as to cause fluid to drain into the tub. The cover for the tub is usually made with a rubber annular ring at its outer edge which fits inside of the casting and serves to deaden noise when the cover is placed upon the tub.

A machine embodying the construction described above is shown in Nelson Design Patent No. 85,259 issued September 29, 1931.

In commercial domestic washing machines of the less expensive type, the die casting, because of the expense involved, is eliminated and the rim of the tub is simply rolled outwardly, or more rarely inwardly, to form a bead extending cir-- cumferentially of the top of the washer tub. The cover used with this type of construction, also usually has a rubber ring fitted to the outer circumferential edge thereof which engages the tub on the inside of the rolled upper edge. A construction similar to that just described is shown in Geldhof Patent No. 1,937,884, issued December 5th, 1933. This construction while much less expensive to manufacture than that employing a die casting is objectionable from an appearance 1935, Serial No. 22,580

standpoint. Further, when the machine is in use the porcelain at the rim of the tub is very apt to become chipped and unsightly due to objects striking the rim.

The primary purpose of my invention is to provide a washing machine construction which is at least as economical to manufacture as the second construction described and at the same time is attractive in appearance, which appearance is as enduring under service conditions as a washing machine employing a die casting mounted on.

the rim of the tub.

Another object of my invention is to provide a washer tub in which the upper edge of the side walls of the tub and the cover are shaped so that any water splashed up on the side walls of the tub by the washing device operating in the tub, or any moisture collecting on the cover, will drip back into the tub rather than leak out between the tub rim and the cover.

My invention further contemplates a washing machine construction which is economical to manufacture and in which the sound deadening means between the cover and the tub rim is mounted on the rim instead of on the cover and the cover is shaped so as to prevent leakage of .fiuid between the cover and the tub and shaped so as to completely hide the rim of the tub when the cover is in position.

Other objects and advantages of my invention will be more apparent from the following description taken in connection with the accompanying drawing, in which:

Figure 1 is a perspective view showing a complete washing machine embodying my novel washing machine construction.

Figure 2 is a vertical sectional view through the cover.

Figure 3 is a vertical sectional view showing a portion of the tub and cover and taken approximately on the line 3-3 of Figure 1.

Figure 4 is a'modified form of the construction shown in Figure 3.

While my invention is equally well adapted for use with washing machines employing a square, or any other shape of tub, for convenience I have shown it as applied to a conventional circular washer tub. The washer tub H is mounted on and secured in any suitable manner to a base l2. The base is preferably a stamping and has a depending skirt l3 for concealing the mechanism for operating the agitator or other washing device mounted in the tub. A plurality of legs Mare riveted or otherwise secured to the skirt, each of the legs being provided with a caster I6.

The side walls of the tub I I extend substantially vertically and near the upper edge, as indicated at H, the side walls are bent or rolled inwardly which serves to strengthen the rim of the tub. The extremity l8 of the rim of the tub is preferably re-bent and has a ring l9 mounted thereon which may be made of rubber or any other suitable noise deadening material. The ring l9 may be fitted to the rim of the tub by cutting a groove in the rubber of the ring which may then be stretched over the re-bent portion l8 of the rim and secured in place in any suitable manner. The rubber ring l9 serves not only to deaden noisewhen the cover is placed or dropped in position on the top of the tub but serves also to protect the rim from becoming deformed in use and prevents chipping of the porcelain at that point. A- further advantage of placing the rubber ring on the tub instead of on the cover, as in the devices of the prior art, is that it enables the housewife to rest pails or basins containing water or clothes on the rim without marring the rim or the likelihood of the pail or basin slipping on the rim while emptying the contents thereof.

A cover 22 is' adapted to rest on the rubber ring l9 and close the opening at the top of the tub. The cover 22 has a skirted portion or depending rim 33 which is adapted to extend downwardly on the outside of the side walls of the tub when the cover is'in position. Any suitable means may be providedfor handling the cover but preferably the center of the cover is countersunk so that the top of a hand grip 23 mounted in the countersunk portion of the cover is approximately fiush with the top of the cover. A screw 26, with which a lock washer 21 is used, extends upwardly through the bottom of the cover and is received in a threaded aperture 28 formed in the hand grip 23. A series of annular ribs are provided which encircle the countersunk portion 24 of the cover and serve to stiffen the cover and decrease the liability ofthe cover becoming deformed in use.

When steaming hot water is placed in the tub, the steam tends to collect on the bottom surface of the cover. At times also water is splashed upon the bottom of the cover by the clothes washing device. To prevent this water, or the steam when it condenses, from seeping between the bottom of the cover and the rubber ring I9, I provide the cover 22 with a head or drip-ring 3|. The drip-ring 3| is formed internally of the portion 32 of the cover, which strikes the top of the rubber ring l9, and lies below that point, so that any water or steam which may collect on the lower side of the cover will gradually collect on the bead and drip down into the tub. The inwardly turned portion ll of the side walls of the tub also decreases the possibility of leakage of fluid between the cover and the tub rim. From.

the point 32 the cover is bent downwardly to form the skirt or depending rim 33. The depending rim 33 extends downwardly on the outside of the inwardly turned side walls I! of the tub and completely hides the rubber ring l9 from view.

tor to place the cover on the top of the tub with- V out the necessity of accurately fitting the cover to the tub.

In Figure 4 I have shown a modified form of the construction illustrated in Figure 3 in which the upper edge of the side walls of the tub is bent sharply inwardly at 36 and then extends upwardly vertically at 31. Upon the upper edge of the tub side walls a U-shaped rubber ring 38 similar to the ring I9 is fitted. The cover used in this construction is essentially the same as that described in connection with Figure 3 except that the proportions of the partsare such that the drip-ring 3| is spaced slightly from the rubber ring 38.

While the washing machine construction shown and described is very economical to manufacture it presents an attractive appearance, prevents leakage of fluid outside of the tub in an effective manner and the cover thereof may be fitted down over the tub noiselessly and with little eflfort. It will be apparent that various changes and modifications may be made in the form and arrangement of the parts without departing from the spirit of the appended claim.

I claim:

In a washing machine construction, a washer tub having substantially vertical sheet metal side walls defining the tub proper, the upper edge of said side walls being turned sharply inward to define a circumferential opening at the top of the tub appreciably smaller than the diameter of the tub proper, and a coverfor the tub having a depending rim, said depending rim at a circumference above its lower edge being somewhat arcuate in cross section and at its lower edge being approximately the same diameter asthe diameter of the tub proper whereby the side walls of the tub proper and the depending rim of the cover give a substantially continuous appearance when the cover is in position on the tub, the relative difference in diameter of the lower edge of the depending rim of the cover and the circumferential upper edge of the tub and the cross sectional curvature of the depending rim of the cover enabling the cover to be somewhat inaccurately placed upon the tub and be seated in its proper position by the cam action of the inside of the cover against the circumferential upper edge of the tub and sound-deadening means between the meeting surfaces of said tub and cover.
