Jan. 10, 1961 J. J. DEVERY DEVICE FOR INTRODUCING LAUNDERING-AID IN'CLOTHES WASHING MACHINES Filed Sept. 29. 1958 INVEN TOR.
Jfl/VEJ J: DEVERY United States Patent 9 DEVICE FOR. INTRODUCING LAUNDERING-AID IN CLOTHES WASHING MACHINES James J. Devery, Ambler, Pa., assignor to Philco Corporation, Philadelphia, Pa., a corporation of Pennsylvania Filed Sept.-29, 1958, Ser. No. 763,878
9 Claims. (Cl. 68-17) The present invention relates to laundering apparatus, and particularly to clothes washing machines of the type which automatically function first to. wash clothes in water contained in a washing basket, then to extract the wash water from the clothes and basket, thereafter to rinse the clothes in water freshly supplied to the basket, and finally to extract the rinse water from said clothes and basket.
In machines .of the above mentioned general variety, better cleaning of the clothes is obtained when laundering-aid material is. added to the water, and it is desirable that the laundering-aid material be introduced into theclothes basket at the proper point in the cycle. Ac-. cordingly, it is an object of thepresent invention to provide an improved device for use. with an automatic washingmachine, which device .is adapted to dispense such material automatically and 'in predetermined relation to the intiation of the proper function of the machine.
While the device of the present invention can be employed to dispense various kinds of laundering-aid materials at different selected times in the sequence of the machines operation, it is preferred to utilize the device for dispensing a rinse-agent, for example, a water-softening liquid or solution, to be added to rinse water during the clothes-rinsing function of the machine.
It is therefore a further object of this invention to pro vide an automatic washing machine with a simplified. device adapted to receive and retain a charge of rinseagent during the washing operation of the machine, and to dispense said agent automatically after the wash water has been extracted from the clothes and expelled from the machine, andwhen freshwater againfills the machine for'the rinsing of the clothes therein.
A' characteristic feature of the invention resides in the fact that. the improved device consists of few inex pensively made parts which can'readily be associated together, for mounting on and removal from an, automatic washing machine without requiring material changes in the machine and without affecting the normal operation thereof;
In. accordance with a preferred embodiment, the device of this invention includes a container which is swingably suspended to tilt within the confines of the washng and spinning basket from a vertcal or material-retaining position to a horizontal or material-pouring position. Movement of the container to pouringposition occurs as a result of centrifugal force generated by displacement of "the material in the suspended container in responseto spinningof the basket to effect extraction and ejection of wash water from the clothes and basket. The device also includes means for'locking the container in horizontal position and preventing said container from gravitating to its vertical position. In this manner, upon cessation of the spinning operation, rinse-agent material retained in said container is free to run outwardly thereof. Inordertoprevent the rinsing-agent material from enteringlthe-clothes-retainingbasket until water in the latter reaches a predetermined level, the-device'of the invention Patented Jan. 10, 1961,
advantageously includes a shallow receptacle disposedibe-g neath the container to catch the material pouring there from. Water which fills the machine basket enters said receptacle and mixes with the rinsing-agent material" therein, the mixture then overflowing into the *basketfor' rinsing the clothes.
The full nature of' the invention and the mannerin. which its objects and advantages are achieved, will be fully understood from the following description taken in conjunction with the accompanying drawings, in which:
Figure 1 is a side view, partly in elevation and partly in section, illustrating a'portion of a'clothes washing machine with which is assocateda dispenser,device'embodying the invention;
Figure 2 is an enlarged top plan view of the dispenser device illustrated'in Figure 1, looking in the general direction of arrows 2--2 thereof;
Figure '3 is a side view of the device. as. shown in, Figure 2, with portions broken away; and
Figure 4 is a fragmentary view, on a larger sca1e, illustrating certain operational features of the devce of this invention.
With more particular reference to the drawing, Figure 1 illustrates those elements of anautomatic clothes wash: ing machine which are necessaryfor an understanding of the invention. The machine itself is of.known. type which includes anoutercasingor cabinet-10' adapted to house a fixed tub 11 which is provided with a drain outlet 12 and which encloses a rotatable washing and spinning basket 13. Thecabinet' has an open top portion 14 which is provided withv a hinged cover. 15'to. give access to the open upper end-14a of said basket.
In a machine of this type, clothes are placed in the. basket 13" and are'washed, rinsed andspun dried.therein., Theclothes are washed by-action of abladed agitator. structure 16 which'is drivento oscillate back'and forth, within'the basketwhile the latter is held stationary, and water isextracted from the clothes and ejected from thebasket by accelerated rotation of the basket and agitator in one direction about a generally vertical. axis, The basketis'imperforate except for overflow portsor apertures l7whichdetermine the normal level of the. water in'the basket and'provide for escapeoflthe water, during spinning of the basket: Water is introduced within'the basket through an,inlet nozzle 18 controlled by means of a suitable conventional solenoid-operated mix; ing valve 19-whichis connected withconduits 20 and 2'1 for supplying hot and cold water. A timer-operated, control'22 havingasetting knob 23 is provided to effect. operation of said valve 19, as well as to govern theautomatic function of the machine through its schedul'e, of washing, rinsing, and water-extracting operations.
The solenoid-valve and the timer-operatedcontrol are. commercial items whichare well known in the art and; to which no claim of invention is made herein. These items therefore have been conventionally represented in, the drawings. Likewise the driving andcouplingmechanism which provides for activation of the agitatorv inthel basket and which also provides for rotation of the.agitator-with the basket in the mannerrpreviously noted, is, commonly known in the art and has not been illustrated.f. Briefly stated the timer-operated control and the driving; and coupling mechanism, as is. generally known in .the... art, function to drive the agitator and basket in the fol.- lowing manner: after the basket 13 is filled with wateri to a level predetermined by thelapertures 17, the agitator.
17; after this extraction, high speed rotation of the basket and agitator structure ceases, the basket is filled with a fresh supply of water and the agitator is again oscillated in the basket to effect rinsing of the clothes; finally, following the rinsing cycle, the basket and agitator structure are once more rotated at high speed for a period of time sufficiently long to extract the rinse water and spin-dry the clothes.
In particular accordance with the present invention, the washing machine is provided with a dispenser device indicated generally at 24. This device comprises a container 26 for receiving and containing laundering-aid material, for instance a liquid rinsing agent, and adapted to empty its contents into the basket 13. As represented in Figure 3, the container 26 is mounted to pivot from a dangling position to a tilted position and, for that purpose, said container is hingedly suspended on a support in the form of an elongated arm 27 which is freely mounted in a generally horizontal position on the upper end portion of the agitator structure and at the open top 14a of the basket 13. As clearly seen in Figures 2 and 3, the intermediate portion of the container-supporting arm 27 is provided with a bore 28 adapted to fit loosely over a pin 29, said arm resting on a shouldered portion 30 of an upstanding post 31. This post is connected by means of an internally screw-threaded portion 32 with the upper end portion of agitator shaft 32a to form an extension thereof.
One end of the arm 27 terminates with a bifurcated portoin defining a pair of parallel bars 34 on and between which the container 26 hangs. Confronting portions of said bars and container have interengageable means providing fulcrum points for pivotal movement of said container from vertical or liquid-retaining position, that is the position shown in full lines in Figure 3, to horizontal or liquid-pouring position, that is the position represented in broken lines in said Figure 3. As best seen in Figures 2, 3 and 4, the mentioned interengageable means take the convenient form of a bayonet-slot type connection consisting of a pair of flattened fingers 35 projecting from diametrically opposite sides of the container 26, and a pair of right-angular slots 36 on the bars 34 to receive said fingers which normally occupy the vertical part of said right-angular slots. This vertical part of each of said slots is such that the fingers 35 are free to swing from vertical position to horizontal positiomas illustrated by arrow A in Figure 4, and the remaining or horizontal part of said slots in such that the flattened fingers can slide into engagement with said horizontal part of the slots, as is represented by arrow B in said Figure 4.
In use, the device 24 is attached to the agitator shaft 32a in the manner hereinbefore described and shown in Figure 3. Before or during filling of the basket 13 with water preparatory to washing the clothes, a measured quantity of a rinse-agent liquid or solution is poured into the container 26. It will be appreciated that because the arm 27 is loosely mounted on the post 31, back and forth movement of the agitator during washing operation of the machine does not afifect the container 26 so that the rinse-agent remains in said container.
Following the washing operation, the arm 27 and container 26 thereon will rotate at high speed with the spinning of the basket and agitator structure to extract and expel the washing water. To insure rotational movement of the arm 27, the latter can be provided with means for interconnecting said arm 27 and basket 13. For that purpose, and as seen in Figure 1, the arm 27 has a pin or projection 39 adapted for engagement with a keeper 40 on the basket 13, so that said arm is positively driven by the spinning basket. Due to centrifugal action resulting from this high speed rotation, the rinse-agent within the container 26 develops a force which causes said container to tilt from its vertical position to its horizontal position, whereupon the flattened fingers 35 align themselves with the horizontal part of the slots 36, and slide into engagement therewith. In this manner the container becomes locked in horizontal or pouring position but, as long as the high speed rotation continues, the rinseagent does not run out of the container but is retained therein by centrifugal action.
When high speed rotation ceases, the rinse-agent is then free to flow out of the container 26, since the latter is maintained in pouring position by means of the fingers 35 which remain in engagement within the horizontal part of the slots 36. However it is desirable that the rinse-agent be prevented from entering the clothes-containing basket until the latter is filled with water. For that purpose a shallow receptacle 38 is provided on the post 31 and extends radially therefrom to underlie the pivotal container 26. With this arrangement, when the rinse-agent is free to flow out of the tilted container, the shallow receptacle 38 intercepts and retains said rinseagent until water rising in the basket 13 enters into said receptacle and mixes with the rinse-agent therein, the mixture being then discharged into said basket as the agitator oscillates back and forth for rinsing the clothes.
If desired a washing aid, such as soap or detergent, can be placed in the receptacle 38 before the machine starts its washing operation. In this manner it is possible to effect automatic addition of washing aid to the wash water as the latter rises in the basket 13 and flows into said receptacle to mix with said washing aid.
After each use, the container 26 can be manually pushed so as to disengage the fingers 34 thereby allowing said container to gravitate back to its normal vertical or liquid-retaining position and made ready for subsequent use. The entire device 24, or the container 26 alone, can be readily removed from operating position so that said device or container can be thoroughly cleaned after use, as desired.
From the foregoing description, it will be appreciated that the present invention provides an inexpensive and simplified arrangement which utilizes functions of an automatic clothes-washing machine to effect automatic adddition of laundry-aid material to water which fills the clothes-containing basket. While a preferred embodiment has been shown and described, it is to be understood that the invention embraces such changes and modifications as may come within the scope of the subjoined claims.
