8 Claims.

This invention relates to washing machines designed for cleansing fabrics of all kinds, one of the objects being to provide a machine of this character that will set up a thorough circulation of cleansing fluid through the fabric.

Another object is to dispense with a wringer on the outside by placing within the tub means by which the clothes may be partially dried before they are taken out of the tub.

A further object is to simplify and otherwise improve upon the construction of mechanisms of this character.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter descibed and claimed, it being understoodthat changes in the precise embodiment of the invention herein disclosd may be made within .the :scope of what is claimed without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

Fig. 1 is a vertical section through the machine.

Fig. 2 is a vertical section on the line 2-2, Fig. 1.

Fig. 3 is a plan View on 1 and 2.

Fig. 4 is a plan sectional view of the anchor plate.

Fig. 5 is a sectional view of the anchor plate.

Referring to the figures by character of reference, 1 designates the tub formed preferably of metal, and the bottom 2 thereof has a relatively large concentric depression 3 in which is placed a filtering screen 4. formed preferably of wire.

The tub is supported by any suitable means, such as legs 5 and has a rounded top 6 with a central opening 7. This opening is surrounded by a flange 8 over which is fitted a gasket 9 and on which rests the lid 10. This lid is readily removable to give access to the contents of the tub and is held in place by the thumb nut 11.

The concentric depression 3 forms a bowl to receive the fluid and suds before it enters the trough 12 from which the fluid passes into the pipe 13, said pipe extending to the circulating pump 14 from which the fluid enters the pipe 15 passing through the four-way cock 16, thence into the conduit 15 heater 17 and out into the pipe 18 where it enters the three-way cook 19.

The heater 17 is arranged at any suitable point relative to the tub 1 and is supported by the line 3-3, Figs.

1930. Serial No. 493,573

cross bars 47 that are attached to the legs 5, the purpose of said heater being to provide hot water during the operation of cleansing the clothes. This can be an electric heater, a gas heater, or any other type designed for heating Water.

Between the three-way cock 19 and the tub 1 is placed a nipple 20 that allows the fluid to pass from the three-way cock 19 into the sprinkling pipes 21 and 21a placed within the tub, one above the other, the purpose of said sprinkling pipes being to distribute the fluid in the form of jets upon and through the clothes.

Above the three-way cock 19 the pipe 22 extends very nearly to the top of the tub 1 where it connects with the sprinkling pipe 23 which surrounds the internal periphery of the tub; the

sprinkling pipes

21, 21a and 23 being pro vided with

holes

24, 24a and 25 through which the fluid is discharged against the clothes lying on the platform within the tub.

Attached to the bottom of the tub 1 is a tube 27 hereinafter called the ram, made preferably of steel and extending downwardly nearly to the floor.

Extending through the lid 10 down into the tub 1 and through the hollow piston rod 31 and piston head 32 is a rod 29, said rod having a threaded upper end and provided with a T-head 30 at its lower end forming an anchor to the rod 29 and bearing on the under side of the plate cover 46, see Figs. 1 and 5, the purpose of said rod 29 being to lessen the strainthe hydraulic pressure exerts on the upper and lower ends of the tub.

Situated below the circulating pump 14 and extending from the ram 27 into the conduit 15 is a conduit 35 supporting a valve cage 36, said valve cage provided with a by-pass and pipe 37 which extends upwardlyinto the T-43. The valve cage 36 contains a check valve 38 to relieve the pressure of the fluid on the bottom of the piston head 32 when the circulating pump 14 is in motion and the fluid is lifting the platform 34 by the pressure in the conduit 35.

A coil spring 39 exerts tension on the check valve 38 and tension upon said coil spring 39 is caused by the set screw 40. Fluid passing from the conduit 15 into the conduit 35 bears on the bottom of the piston head 32 of the ram 2'7. When the pressure exceeds a certain amount at the point of contact with the fluid between the piston head 32 and the check valve 38, said valve rises, permitting the excess fluid to pass up into the valve cage 36 and escape 110 through the by-pass and pipe 3'7 into the T43 to be returned to the circulating pump 14 through the pipe 13.

A motor 41 placed beneath the tub 1 ,is connected with the circulating pump 14 by the shaft 42, its purpose being to rotate the pump and operate the ram 2'7 when necessary, causing the fluid to be set in motion for cleansing the clothes.

Between the valve cage 36 and the conduit 15 is placed a T-cock 44, its purpose being to control the flow of fluid from or to the ram 27.

Following is the mode of operation:

Fluid is admitted into the tub from the service main or other sources into the pipe 26, thence through the four-way cock 16, into the conduit 15a, or into the circulating pump 14, the pipe 13, and the trough 12, there being two separate ways by which fluid may enter the tub from the mains.

When sufficient fluid has entered the tub 1 the T in the four-way cock 16 is changed so as to stop the flow from the main. In making the change the fluid will now'circulate through the tub I in the following manner: the fire is ignited under the heater 17, the motor 41 is started, the fluid is drawn from the trough 12 down through the pipe 13 entering the circulating pump 14, then passing in to the pipe 15 through the T-cock 16 into the conduit 15a to the heater 1'7 and up into the tub 1.

The clothes to be washed are placed on the platform 34 which may be either .at the top or bottom of the tub. Should the platform be at the top of the tub, by opening the T-cock 44 it will descend to the bottom thereof. The lid 10 is lowered to rest on the gasket 9 above the flange 8, and the thumb nut 11 is securely screwed down into place; then the fluid is discharged through the

holes

24, 24a and 25 and circulates through the clothes, thereby th0rough-.

ly washing them.

After suflicient time has elapsed for washing the clothes the three-way cock 19 is closed and the T-cock 44 is opened so that the fluid from the trough 12 is drawn into the circulating pump 14, thence into the pipe 15 and the conduit 15"- enters the conduit 35 and passing through the T-cock 44 and into the bottom of the ram 27; in so doing, the clothes resting on the platform 34 are lifted from the fluid and pressed against the under side of the lid 10. When the pressure is suflicient to remove the excess moisture from the clothes, the T-cock 44 is changed to shut off the supply of fluid from the pump 14, and the platform 34 remains at the top or end of its stroke.

When the lid 10 is removed, the platform 34, containing the clothes that have just been washed, and not rinsed, is lifted out and another platform containing more clothes to be washed may be placed on the end of the piston rod 31, the lid 10 replaced, and the three-way cock 19 and the T-cock 44 opened, permitting the platform to descend; then the T-cock 44 is closed, the motor is started again and the work of washing more clothes is resumed.

After all the clothes have been washed the four-way cook 16 is changed again back to its original position as hereinbefore mentioned so that the fluid and suds may be discharged into any convenient receiver through the drain pipe 26.

The rinsing process is accomplished by changing back the four-way cock 16 whereby clean fluid is drawn into the tub through the pipe 26, the four-way cock 16 and the conduit 15, into the heater 17, or through the circulating pump 14, and the pipe 13 into the trough 12. The fluid may be admitted into the tube either through the top or bottom sprinkling pipes contained therein.

Then the drying process takes place, as hereinabove described, the lid 10 is removed, and the platform containing the clothes, is lifted out.
