BY 5% z? rates 2,868,006 Pal tented Jan. 13, 1959 time CLOTHES TREATING LIQUID DISPENSER FOIR AUTOMATIC WASHING MACHINES Loyal H. Tingley,-Llr., Vermont, Ill. Application January 13, 195 6, Serial'No. 559,011 14 claims. (Cl. 68-207) In the operation of automatic Washing machines, the

articles of clothing along with the soap or detergent are positioned in the tub after which the machineautomatically fills with Water, washes the clothes for a predetermined interval-s, spins out or centrifugally extracts the wash water, stops the tub and refills the same with rinse water, thoroughly rinses the clothes and then spin dries the clothes. In some instances, it is desirable to insert or pour liquids or other material into the rinse water for treatment of the clothes. .When this is desired, it is necessary for the housewife or person operating the washing machine to listen to or observe the various stages of operation and insert the desired material at the proper time. This requires the attention of the housewife, thereby eliminating some of the advantages of the automatic washing machine. Accordingly, it is the primary object of the present invention to provide an attachment for automatic washing machines which will automatically dispense the'desired"quantity of clothes treating fluid or other flowable material into the rinse water at theproper time, thereby rendering the cycle of operation completely automatic. 7 V

Yet another object of the present invention is to "provide an attachment for automatic Washing machines as set forth in the preceding paragraphs which is extremely simple in construction, provided with no moving parts,

easy to attach t'ofexisting washing machines, foolproof in operation, well adapted for its intended purposes and extremely-inexpensive to"h'ianufacture.

These together withother objects and advantages which will become subsequently apparent 'reside in the details of construction and operation as more fully hereinafter described and claimed,'reference being had to the'accom- "panying drawings jforming a part hereof, wherein like numerals'rfertolikeparts throughout, and in which:

Figure l "is aside elevational view vof an automatic clothes washingniachine with the dispensing device atta'chc d/tothe agitator, portions of the machine being "broken away to more clearly illustrate details of the structure;

"Figure'Z is a perspective view of'thedispensing attachment of the present invention;

Figure 3 is a detailed transverse sectional View -illus tratingfthe device attached to an agitator or impeller fillustifziting the initial position of the clothes treating liquid .prior to beginning of the washing machine cycle and during the initial agitation of the clothes during the wash- "p'elle is spinning "the wash water away from the clothes;

'Fig'me 5 is asec'tional view similar to-Figures 3 and 4 2 illustrating the .next step of operation of the dispenser wherein the agitator has stopped and the tub is being refilled with rinse water and the liquidis being discharged into the rinse water through the. discharge openings; and

Figure 6 is a vertical sectional view of a modified dispensing attachment.

Referring now specifically to the drawings, there'is disclosed in Figure 1 an automatic clothes washing machine comprising a cabinet 1 in which is disposed an outer tub 2. Positioned within the outer tub 2 and arranged for rotation relative to the outer tub, is an inner clothesreceiving tub or basket 3. A motor and gear unit '4 is provided to impart an oscillatory motion to an agitator 12 during the wash cycle and to rotate the basket 3 at high speed during the extraction cycle. The agitator is oscillated by a. polygonal vertical drive shaft '14 connected to the transmission and having an internally threaded socket 16 at the upper end thereof for receiving the exteriorly threaded stud 18 on a cap 24? which normally retains the impeller or agitator 12 on the shaft and permits removability thereof for cleaning.

'The numeral It) generally designates thedispensing attachment of the present invention for attachment to the impeller 12 or agitator of the automatic Washing machine. lidore particularly, the dispensing attachment '10 includes an annular container generally designated by pern'iitting passage of the externally threaded stud 18.

By positioning the plate 32 against the upper surface of the shaft 14 and impeller 32 and then inserting the stud 13 into the socket 116 and tightening the cap 2l, the device llll may be securely and detachably attached to the impeller 12.

'Dispo'sed concentrically between the inner and outer walls .24 and 26, is a vertically disposed bafile 36 integrally formed with the bottom wall 36 and spaced slightly below the upper wall 23 to provide a communication passage between an inner compartment or receptacle section 38 andnn-outer compartment 5a. Disposed in the top wall 28 is an access opening 42 having a removable closure "plug 44 therein, the opening 42 being disposed over the inner compartment 38 for permitting liquid 46 to be introduced into the inner compartment 38.

Circumferentially arranged in the bottom wall 30 is a plurality of discharge openings 48 located just exteriorly of the baffle ,plate 36 for permitting discharge of the liquid 46 downwardly from the outer compartment 40 through the bottom wall 30 in a manner described hereinafter.

in the operation of the embodiment of the invention specifically illustrated, the dispenser 10 is attached to the impeller 12 in a manner described previously and may be retained thereon for extended periods of time .and only removed when the impeller is removed for cleaning or the like. The closure plug 44- is removed and a desired quantity of fluid 4-6 is poured into the inner compartment 38 at the same time as the clothes positioned in the tub and the detergent or soap disposed therein after which the automatic washing machine is put into operation. The tub is initially filled with Water and the impeller 12 begins its oscillation movement after the water in the tub has reached a predetermined level. The oscillation of the impeller '12 continues for a predetermined length of time and during this oscillation, the fluid 46 will have a slight back and forth movement in the inner compartment 38 but due to the absence of any prolonged centrifugal force, the liquid 46 will be retained in the inner compartment by the barrier formed by the 'baffle'36. After the washing operation has been completed, the tub and impeller 12 spin as a unit for spinning out or extracting the Wash water by centrifugal action. During this spining operation, the fluid 46 is acted upon bycentrifugal force and is forced upwardly over the upper edge of the baffie 36 and into the compartment 40 substantially as illustrated in Figure 4. The side wall 26 and the adjacent portions of the top wall 28 and bottom wall 33 form an outer wall that is generally U, C, or trough-shaped in cross section and is disposed outwardly of the receptacle section 38 and defines a space that opens toward the axis of rotation of the dispenser and is in communication with said receptacle section. During the spinning movement of the impeller 12 and the tub, the fluid as will be retained against the inner surface of the outer wall 26 by centrifugal force which will retain the fluid 4-6 away from the discharge openings 48 in the bottom 3%. The openings 48 are located radially inwardly of the side wall 26 a sufficient distance to prevent discharge of the rinse agent therethrough during the centrifugal extraction operation but are effective to drain the rinse agent from the dispenser at the end of the centrifugal extraction operation for use in treating the rinse water in the washing machine during the rinsing operation. Due to the increase in radius of the .fiuid 46 as it moves from the inner compartment 38 to the outer compartment 40,- the outer compartment 40 may have less cross sectional area. During the complete spining operation, the fluid 46 will be retained against the inner surface of the outer wall 26 and after the spinning operation, the drain line from the tub is automatically closed and the tub and impeller come to a stop. The tub then is refilled with rinse water and while the rinse water is being discharged into the tub, the liquid 46 will flow through the discharge openings 48 by the force of gravity into the rinse water for thoroughly intermingling with the clothes during the agitation of the impeller 12 during the rinsing operation.

It will be understood that various types of liquid clothes treating material or chemicals may be employed such as a recent commercially available material for making the clothes soft and flutfy when laundered. However, it will be clearly understood that any materials of a liquid nature may be employed such as blueing or starch wherein it is desired to discharge the liquid material into the rinse water.

The entire device may be constructed of any suitable material such as plastic or metal although plastic lends itself to relatively inexpensive manufacturing cost. While the device has been specifically illustrated as having a closure plug, any type of closure cap or closure member may be provided which is securely retained in position during the spinning operation.

In some types of automatic washing machines, two rinsing operations are provided each preceded by a centrifugal extraction operation and if this is the case, it would be only necessary to provide a duplicate arrangement, as illustrated in Fig. 6 of compartments 38' and 40 axially of the first and second compartments 38 and 40 and axially spaced therefrom which would be identical in construction except that the inlet for the concentric inner compartment of the duplicate arrangement would receive the liquid from the discharge openings 48 of the first arrangement. Primed reference numerals are employed in Figure 6 to designate parts corresponding to the parts in Figures 2-5. While the device has been specifically illustrated as being attached to the impeller or agitator, the device may be attached to any: of the rotating and oscillating elements employed in automatic machines such as the shaker type tub. Also, the device may be cast as an integral part of the impeller, agitator or other movable element of the machine.

The foregoing is considered as illustrative only of the 4 principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
