A. J. WILTSHIRE WASHING MACHINE Filed May 12, 1938 INVENTOR. HR THUR J. W/LT6H/RE ATTORNEY Patented Feb. 4, 1941 UNITED STATES PATENT OFFICE WASHING MACHINE Application May 12, 1938, Serial No. 207,486

'5 Claims.

This invention relates to washing machines and more particularly to an improved apparatus for controlling the water supply employed to carry out different laundering operations.

It is among the objects of my invention to provide a fluid discharge fixture for controlling the water conducted to a washing machine and directing the water into laundering compartments of the washing machine.

10 -More specifically it is an object of my invention to provide a water discharge fixture for that type of washing machine known as the washer-extractor type, wherein the clothesare washed in one compartment and the water is thereafter 15 extracted from the clothes in an adjacent compartment.

It is also among the objects of my invention to provide a fixture in accordance with the preceding objects, which is an improvement and/or modi- 20 fication of a fixture having'certain advantages present in a fixture such as disclosed and claimed in the patent of Walter A. Frantz and John J.

McCabe, No. 2,154,566, issued April-18, 1939.

It is a further object of my invention to provide 25 a fluid discharge fixture for washing machines of the type mentioned, wherein a nozzle is arranged to discharge water into either of two laundering compartments and the control of the nozzle is efiected by a manipulation of the fluid conduit 30 which leads the fluid to the machine.

It is also an object of my invention to provide a fixture in accordancewith the preceding object, wherein a valve is arranged to be automatically controlled by the movements of the nozzle and 35 conduit with respect to the washing machine.

Further objects and advantages relating to efiiciency in operation and economies in manufacture will appear from the following description and the appended drawing, wherein:

Figure 2 is an enlarged sectional view taken along the line 2-2 of Figure 1;

Figure 4 is a view taken along the line 4-4 of Fi ure 2. H I

Recent developments in the domestic laundry 50' art have led to the general use of a washing machine which is known as the washer-extractor type and I have illustrated in Fig. 1 a machine of this character, wherein a base frame E'supported by a plurality of legs 6 carries a pair of laundry 55 compartments 1 and 8. The compartment 1 is ordinarily provided with an agitator 4 which is designed to wash the clothes immersed in a solution of soapy water. The compartment 8 is provided with a spinner basket or the like, indicated generally as at 9 and the clothes subsequent to 5 their washing in the compartment I are transferred to the spinner basket 9 where theyare rotated at a relatively high speed, such as for instance 1000 R. P. M., until the water has been centrifugally extracted from the clothes. 10

It will be understood by those familiar with this art that the underside of the base frame 5 is provided with an electric motor and suitable gearing or driving mechanism to efiect a. washing of the clothes in compartment I and the spinning of the basket 9 in compartment 8. It will also be understood that both compartments I and 8 are provided with suitable drains for emptying said compartments. The extractor compartment 8 is provided with a cover l2, hinged as at I3, and said cover is interlocked with a control lever l4 arranged to start and stop the rotationlof the spinner basket. The interlock between the control for the spinner basket and the cover i2 is a safety feature developed to remove danger of in- Jury to the-user of the machine and in general the operation between the lever l4 and cover 12 is such that the spinner basket 9 cannot be rotated by turning the control M to position Ila unless the cover I2 is in its lowered position as in Fig. 1. In the machine illustrated the control lever ll carries an arm 3 which swings in an arc adjacent a tapered member 2 fixed to the cover hinge pin. when the cover is in an open position the member 2 extends into the are described by arm 3 and prevents swinging of the control lever ll to the position I la. The provision of an interlock between the extractor drive and the cover for the extractor compartment 12 is now a statutory requirement in certain states and it is believed that eventually a requirement for such a safety interlock will be universal.

In accordance with the said patent of Walter A. Frantz and John J. McCabe, it has been proposed to rinse the clothes within the extractor basket 9 with fresh, hot water, during the operation of the extractor, by swinging a hot water discharge nozzle beneath the extractor compartment cover. This is found to be a most desirable and eificient method of rinsing the clothes in this type of washto discharge water into the washing compartment 1. The fluid discharge fixture according to my invention comprises a main body part l5 which is mounted for oscillation about a vertical axis in an aperture formed in the deck I 6 overhanging the extractor compartment 8 and the washing tub 1. The body. portion l5 of the fixture is secured to the deck l6 by passing the cylindrical part l8 upwardly through the aperture in the deck and securing the nozzle portion IQ of the fixture thereon by means such as the bolt 2|. A pin or the like as at 22 prevents rotation of the nozzle part IS with respect to the body portion ofthe fixture and thus the nozzle and fixture are bodily rotatable as a unit with respect to the deck IS. The part I9 is provided with a shoulder I90 adapted to bear against the deck l6 and prevent axial movement 'therof when assembled on said deck. Water is conducted to the fixture by means of a flexible hose 23 and a valve "24: is arranged to control the 1 passage of the water from the conduit 23 through chamber 26 and thence to be discharged through the nozzle by way of passage 28.

Since the entire discharge fixture is arranged to swing bodily with respect to the washing machine in directing the water to the proper compartmen-t, I prefer to utilize such swinging movement to effect an opening and closing of the valve 24 in the illustrated embodiment. I have ob,- tained an automatic opening and closing of the valve in response to the swinging movement of the fixture by mounting a pair of a-rcuate cam plates 30 and 3| on the underside of the deck IS in a position to bear against the stem 25 of the valve 244 The cam'plates 30 and 3| are spaced from each other .as shown in Fig. 3 so that the valve 24 will remain in its seated position as the discharge nozzle l9 swings over the imperforate part of deck l6. When, however, the discharge nozzle I9 is disposed over the tub I, as at Ma, or over the spinner basket 9 asat l9b, the valve stem 25 will be forced downwardly to permit water to flow.

into either of said compartments. The valve is normally urged to its closed position by means of a spring 21 and the valve stem is provided with a conventional packing gland as at 29.

To .prevent the rust and scale ordinarily present in domestic hot water systems from entering the valve '24 and the laundering compartments of the washing machine, I prefer to provide a filter as at 35 in the inlet portion 36 of the fixture. The filter as employed in the illustrated embodiment comprises a conical wire screen 31' surrounded .by a cone 38 of fibrous material. The end of the hose 23 remote from the washing machine is connected as at 40 to the service water supply and the length of the hose 23 is such that it will allow the free bodily swinging movements of the end secured to the machine as illustrated at 23a and 23b. With the arrangement ofthe or movements of the hose caused by surges of water therethrough will swing the nozzle, I have provided a latching device indicated generally as at 42. The lat-ch device comprises a member 43 secured to the underside of the deck [6 and carrying a spring pressed ball 44. The body portion of the fixture is provided with a flange 45, oppovalve 24;

compartment I, they may be transferred to the.

site the member 43, and said flange 43 is apertured as at 46, 4'! and 48 to receive the springpressed ball. With the latching arrangement above described, the hose member 23 may be manually moved so as to swing the fixture to either of the three positions shown and the fixture will be impositively held in said positions by the ball and recess latch 44, 46, 41 and t8.

Referring .briefly to operation of a washing machine embodying my invention, it will be understood that water with a temperature suited for washing operations may be discharged through the service tap 4i, thence through the discharge fixture with the hose positioned as at 230. to conduct the wash water into the tub I. A swinging of the hose to position the nozzle I! over the deck It will bring about a. closing of the After .the clothes have been washed in spinner basket 9, the cover I2 closed and the spinner control l4 operated to place the spinner basket in rotation. During the rotation of the spinn'er basket, the service water taps may be regulated to discharge a very hot or sterilizing rinse water into the hose 23. A manual swinging of the hose from its neutral position, as shown in full lines in Fig. 1, to the dotted-line position 23b,

will effect an opening of the valve 24, and direct the hot rinse water into the spinner basket. When the clothes have been sufiiciently rinsed, the hose may be again swung to its neutral position so as to close the valve 24 and the spinning operation continued until the rinse water has been extracted from the clothes.

From the construction of the discharge fixture which I have provided, it will be observed that the water pressure in the conduit 23 supplements the action of the spring 21 in holding the valve 24 seated and that the swinging movement of the fixture eliminates the need for large packing glands or packing washers .around the rotating parts of the fixture. The simple poppet type of valve is relatively inexpensive to make and will remain leak-proof over long periods of use. The cam plates 30 and 3|, being secured to the underside of the deck l6, by means of the screw and slot arrangement 49-50, provide for an accurate adjustment as to the opening and closing of the valve 24 in-response to swinging movement of the hose.. -A further advantage associated with a fixture such asI have provided, flows from the fact that it comprises essentially two castings which are secured to each other and mount the fixture upon its support by means of a single bolt as at,2l. This arrangement results in low manufacturing and assembly costs.

From the foregoing description of one form of my invention, it will be appreciated that I have for a washing machine which will be relatively inexpensive to manufacture and assemble and which will safely facilitate the laundering opera'-' tions.

Although I have shown and described one embodiment of my invention in considerable detail,

it will be understood that numerous changes may be made therein by those skilled in the art, without departing from the scope of the invention as defined in the following claims:
