rlhis invention has reference to washing machines and more particularly to ymachines intended for domestic use, and it has for its principal object to improve the supportlng structure for the tub of-such machines and incidentally the wringer column and the transmission case. i

rlhe invention has for a further object to improve the supporting structure for the tub of washing machines, particularly where the metallic tub hasV applied to one or both surfaces thereof a vitreous enamel.

In machines employing metallic tubs, `the surfaces of which are covered with vitreous enamel, it is obvious that the legs or standards supporting the tub and incidentally the wringer column and the transmission case, must be secured to the tub at points-above the normal water line of the tub and preferably adjoining the upperedge of the tub to avoid checking the enamel at points where leaking would naturally result. Other and further object-s will more fully appear from the following description.

rlhat the invention may be more fully understood, reference isrhad to the accompanying drawings formlng part `of this description, illustrating a preferred embodi ment of the invention, in'which f Fig. 1 is a perspective view of a well known type of washing machine, the inner and outer srfaces of which have applied thereto a vitreous enamel and including a supporting structure embodying my invention; l

Fig. 2 is a detail plan in section, as the same would appear if taken on the line V2 2 Fig. 1 Fig. 3` is a detail plan in section, as the same would appear if taken on the line 3-3 1928. serial No. 25a345.

sponding parts throughout the `several figures.

In the drawings, the tubbl, which is preferably shown square has vitreous enamel apas to be coincident or disposed in axial alignment with the column 5 and forming in effect a continuation thereof, the said column 5 and the leg or standard section 4b having attachment with upper and lower sections 6 and 7 respectivelyof a transmission case 8', and the said leg or standard section 4a having attachment with the tub and the upper section 6 of the transmission case 6, being spaced from and lying parallel alongside the column 5. The legs or standards 4 and the lower section 4b of the sectional leg or standard have attachment with and support a base plate 9, and to the saidlegs or standards 4 and to the said leg or standard section 4b are secured tubular bearing members 10 through which are adjustably carried caster legs 11, to the lower ends of which are connected swiveled caster wheels 12.. The said legs or standards` 4 and the said leg or standard section 4a are angular in shape, see Figs. 1, 3, 4 and 5 so as to embrace or overlap f two sides of the tub, at the respective corners, and such shape form a partial enclosure for the caster legs 11, as shown.

The upper section 6 of the transmission case 8 is formed with or has connected there-' with an angularly shaped casting or bracket v13, to which -is secured the lower end of the leg or standard section 4a, see Figs. 1 and 3, and the lower section 7 of the transmission case 8 is formed with or has conne'cted therewith an angularly shaped casting or bracket 14 to which is secured the upper end of the leg or standard 4b, see Figs. 1 and 4.

r rlhe transmission case 8, as shown, extends radially outward from on or about the axis of the tub to a corner of the tub to allow for the connections with the upper and lower sections 6 and 7, above described, and the inner end of said transmission case has extending upwardly therefrom a suitable bear! ing and vertical agitator driving shaft, not shown, which is disposed axially of and within the tub and associated therewith is a suitable water-seal, not shown, common in devices of this character.

'llo the upper end of the column 5 is swingablyattached a wringer support 15 carrying the usuallwringer mechanism 16, the actuating means of which is adapted to be driven by a shaft 17, see Fig. 2, housed within the column 5 and adapted to receive its power from driving means, not shown, housed within the transmission case 8.

rllhe head frame 2 is formed or provided with the off-set upwardly extending flange 18, see Figs. .3 and Z7, which overlies the upper edge of the tub, and at the corners of the tub over-lies the upper ends of the legs or standards d and the said leg or standard section de, and said head frame is further formed or provided with the inset depending fiange 19, see Figs. 5 .and 7 which is disposed within the tub and lies next adjacent the inside face of the wall of the tub, as shown.

ln Fig. 5 the fiange 19 is of a depth to permit of' securement of the legs or standards 4 and the said leg or standard section 4ta to trie wall of the tub and the said fiange 19 by rivets or equivalent securing means 20. in Fig. 7 this fiange 19 is somewhat shallower and therefore the securing means 20 passes only through the leg or standard t and the wall of the tub. These securing means, as will appear, are all above the normal water line in the tub and even though checking of the enamel should occur at these points it will not be material, as nopacking will be required as there is no chance of leak. Che tub is preferably of pressed steel capable of having applied thereto the vitreous enamel surfaceor surfaces, but minus the usual depending lugs or brackets to which the legs or standards are usually secured to, and therefore such legs or standards are shaped to provide rather ext-ended surface bracing portions` and secured to the tub above the normal water line. Brazing or welding leg `or standard securing lugs or brackets to the tub body is not at all practical when applying vitreous enamel surfaces thereto, as will understood by those skilled in the art.

At the wringer column corner of the tub a bearing bracket 21 is secured to receive the upper end of the column 5 and said bracket 21 is secured direct to the flange 1.8 of the head frame 2 and at this point the said head yes frame 2 is provided with strengthening ribs seamos 2 to brace the ange 18 against the lateral and torsional strains arising from the diderent positions into which the wringer frame 15 may be swung. ln Fig. 6 I have shown that instead of securing the bracket 21 to the flange 18 of the head frame 2 this connection may, if desired, be made through the leg or standard section 4a, the wall of the tub and the flange 19 of the head frame.

l/Vhat l claim is 1. ln combination, a metal tub, metal legs supporting said tub and having extending bearing surface portions embracing the sides of the tub and extending adjacent to the upper edge of the tub, a head frame having an off-set upwardly extending flange in substantially the vertical plane of the side walls of the tub and overlying the upper edges of the legs and having an inset depending iange within the tub next adjacent the walls of the tub, rand a common means securing said inset flange to the walls of the tub and the legs to said tub body.

2. ln combination, a metal tub, metal legs supporting said tub and having extending bearing surface portions embracing the sides of the tub and extending adjacent te the upper edge of the tub, a head frame having an off-set upwardly extending fiange substantially the vertical plane of the side walls i of the tub and everlying the upper edges of the legs and having an inset depending flange within the tub next adjacent the walls of the tub, a. common means securing said inset flange to the walls of the tub and the legs to said tub body, and a base plate connecting and bracing the lower ends of the legs.

3. lln combination with a tub and legs having upper portions engaged with the outer side face of the tub and terminating substanl tially at the top edge of the tub, a head frame mounted on the upper end of the tub and having a laterally offset upwardly extending iiange and an inset depending dange engaged with the inner side face of the tub, said offset flange having its outer side face disposed substantially flush with the outer faces of the said upper portions of the legs and having a bottom edge disposed in close proximity to the said upper terminals of the legs, and means 'to secure the legs to the tub near said head frame.

4. ln combination, with a metallic tub, of metallic legs supporting the tub, a transmission case comprising upper and lower sections disposed beneath the tub and extending outwardly from and connected with the center of said tub and intersecting a leg, said last mentioned leg comprising an upper section embracingand secured to the tube and a lower l2 EGG of the lower leg section, a column having its lower end secured to the upper case section in vertical alignment with the lower leg section s0 as to form a continuation thereof, and means rigidly connecting the column and tub adjacent the upper end of the latter.

5. In combination with a metallic tub, of metallic legs supporting the tub, a transmission case comprising upper and lower sections disposed beneath the tub and extending outwardly from the center of the tub and intersecting a leg, said last mentioned leg comprising an upper section which is engaged over the outer face of the tub and which extends to adjacent the top of the tub and is rigidly connected to the tub at. its upper end and a lower section odset vertically in relation to the upper leg section, connecting means between the upper case section and the lower end of the upper leg section and substantially alined with the latter, and connecting means between the lower case section and the upper end of the lower leg section.

In Witness whereof, I have hereunto affixed r my hand this 25th day of February, 1928.

ALPHEU'S W. ALTORFER.
