'Z Claims.

This invention relates to improvements in washing machines, and has `for its object the -provision of means for mounting porcelained or vitreous enameled tubs upon the base or support in such a manner that expansion and contraction may occur without injury to the enameled surfaces of the tub.

It is particularly the object of this invention to provide a base or support for .a tub upon which l@ the tub is mounted upon resilient discs or gaskets in such a manner that anyy movement of the tub in relation to the chassis will not injure the surfaces of the tub. It is also an object of this invention to provide l5 in connection with a porcelained tub a faucet thereon so connected to the tub that it can be easily removed, and when in place is guided by a side flange of the chassis. v

It is also an object of this invention to provide in connection with the base or support having a standard, a means for supporting the tub from a standard in such a manner that a limited amount of movement is permitted to the tub without the outside surface of the tub coming in contact with the parts of the standard that support it. For this purpose there is provided in connection with the supporting means attached to the standard a plurality of rubber discs engaging the tub in such a manner as to hold it but at the same time permit a limited amount -of movement of the tub.

These and other objects Will appear inthe following description taken in connection with the drawings.

Referring to the drawings:

Figure 1 is a View showing a vertical section of the tub and the base or support, together with the standard and gear case.

Figure 2 is an enlarged view of the arm 9 extending from the standard and shows the means by which the side of the tubis attached to the standard. f'

Figure 3 is a top plan view of the base or sup-2 port. Figure 4 is a section on the line 4 -4 of Figure 1.

Figure 5 isa section o n the line 5-5`of Figure 1.

Figure 6 is a section on the line 6 6 of Figure 3.

This invention relates to Washing machines, and particularly the manner of mounting the tub upon a base or support l. This base or support is circular in shape, and has extending downwardly from the periphery thereof a flange 2.

(Cl. (iS-l5) The central part of the base or support has an opening 3 through which the operating shaft. extends from the gear within the gear housing.

Located around the opening 3 and beneath the base or support is a bracket ring 4, which has extending downwardly therefrom a plurality of arms 4 ending in a plate or disc 5. To this plate or disc is attached a gear case 6, which is also further supported from the chassis by means o1 a bolt connection?. Extending from one side of the gear housing and external to the base or support and the tub is a standard 8, which has extending from one side thereof an arm 9 the purpose of which will be described hereinafter.

In the base or Vsupport there is a plurality ofi@ depressions 10, which have extending through the bottoms thereof holes'through which bolts l1 extend for the purpose .of fastening legs to the base or support. On top of the heads of the Y bolts in the depressions are resilient discs 12 of 7i substantially the same size the depressions are. These resilient discs are for the purpose of supporting the bott'om of the tub upon the base or support. Supported upon the base or support is a tub having sides 13 and a bottom ,14. The bottom of the tub rests upon the resilient discs 12 and has in the center thereofl an opening 15 in line with and the same size as the opening in the base or-support.

Between the base orsupport and the bottom of the tub and surrounding the openings in the base or support and the tub is a rubber washer 16. Extending upwardly from the center of the tub is a dolly standard 17, which has at its lower end a base ange 18 resting upon a rubber washerl or gasket 19 between the basev ofthe dolly standard and the bottom of the tub.

As shown in Figures 1 and 5 these 'parts are attached to each other by vmeans of screws 20 which pass through holes 21 in the bottom of the 95 tub and holes 22 in the base or support. These holes are somewhat larger than the screws 20 to .permit movements of the bottom of the tub and the base or support in relation to these screws. These parts are rmly held together by means of the screws 20, which may be easily placed in position and may be easily removed therefrom. For the purpose of holding the parts assembled,

as shown in these gures, the threadedends of the screws are threadedinto the bracket ring 4 105 beneath the base or support.

As shown in Figure 3 there is a plurality of resilient discs 12 associated with the` bolts for attaching the legs to the chassis. Upon these resilient discs the tub rests and is supported, while the central part of the bottom of the tub is supported on the annular gasket or washer 16.

It is obvious that a tub supported in the manner hereinbefore shown and described may havea certain amount of movement without the surfaces of the tub becoming injured. Inthe case of enameled tubs it is very necessary that the surface of the tub be kept free from scars and chipped places. It is therefore the object of this invention to provide means for supporting a tub in such a manner that all supporting contacting surfaces are lined with resilient discs or resilient gaskets so that no contact of enameled surfaces with metal is permitted, the tub being supported at all points from direct contact with .any of the metal parts of the supports.

'I 'o one side of the tub and in the bottom thereof there is a conical depression terminating at 4the bottom into an orifice 23, circular in shape.

There is also in the part of the base or support adjacent the hole 23 of the tub a hole 25 in line with but considerably larger than the orice in the tub. This hole in the base or support is for the purpose of accommodating a faucet 26, which is attached to the downwardly turned edges of the orifice 23 and extends through the hole 25 in the base or support.

'I'he upper end of the faucet is ared at 27 and nts on the outside of the downwardly turned edges of the orice 23 as hereinbefore described. On the inside of the faucet adjacent the flared mouth is a threaded throat 28, into which a flared nipple 29 is threaded. This ared nipple threaded externally on its cylindrical portion 30 screws into 4the internally threaded throat part of the faucet. The upper end of the spout 29 is :flared at 31 and conforms to the general shape ofxthe ared mouth of the faucet but providing a space therebetween for the fiared edges of the orifice 23 hereinbefore described.

Between the part 31 and the downwardly turned edges 24 is a resilient gasket 32, while between the flared mouth 27 and the downwardly turned edges 24 is a gasket 33. 'I'hese parts are shown in Figure 4.' The parts 31 and 27 are clamped against the gaskets by the rotation of the spout 29, bringing the parts close in relation to each other so that the-gaskets are compressed between the parts 2'7 and 31 respectively, and the downwardly turned edges 24 so that when the nipple is screwed down the faucet is held rmly to the bottom of the tub so that no solution can leak through the connection between the two.

In the lower and outer end of the faucet is a valve 34 operated by means of a valve stem 35 threaded into an opening in the wall of the faucet. This stem and valve are operated by means of a wing structure on the outer end of the stem. 'I'his wing structure extends through a slot 36 in the peripheral flange 2 of the base or support. This slot permits a certain amount of movement of the valve stem without being interfered .with by the walls of the fiange. neath the valve stem there extends a-locating stud 37. This stud projects from the faucet through opening 38 in the ange of the base or support. .This opening is below the opening 36 and permits a free movement of the faucet without being interfered with by the ange of the base or support. The large hole 25 in the base or support permits a movement of the faucet without engaging the base or support either by any movement of the faucet and the tub.

,Forthe purpose of supporting the side of the tub there is provided in connection with the arm Ber 9 an opening 39 in the wall of the tub, a resilient gasket or washer ring 40 between the arm and thetub, a similar resilient washer 41 on the inside of the tub, a cap member 42 fitting over the resilient washer 41, and a bolt 43 passing through the cap, both resilient washers, through the opening 39 and through a hole in a projection on the arm 9. By this means the side of the tub is held by the standard 8 in such a manner that a limited amount of movement can occur to the tub without the surface of the tub'coming into contact with any object other than that of the resilient washers or gaskets. In order to provide for this movement and this protection, hole 39 fdiametrically larger than the bolt is provided ffor the bolt 43.

It is obvious from the foregoing description that any part of thel tub cannot contract with a metal surface or metal support, all contracting points of the surfaces of the tub being supported by a resilient disc or gasket. It is also obvious that any slight movement of the tub permitted by these resilient gaskets can be effected without any part of the tub becoming marred or worn by contact with a hard metal surface. It is also obvious that the faucet, supported from the bottom of the tub,Y is attached in such a manner that there is a watertight connection between the bottom of the tub and the faucet, and that the faucet is also located by openings in the periphery of the base or support in such a manner that it can have a limited amount of movement Without coming into contact therewith; at least without coming into contact with the base or support in such a manner as to cause marring or breaking of the apparatus or machine. This support for the tub is particularly advantageous to tubs composed of metal porcelained or vitreous enameled.
