Filed Dec. 11, 1956, Ser. No. 627,659 7 Claims. (Cl. 68-24) This invention generallyrelates to a dispensing device and more particularly to an attachment for tumbler type washing machines for automatically dispensing clothes treating material into the automatic washing machine at a predetermined time during the washing operation.

Specifically, the present invention represents a 'modified form of the device illustrated and claimed in my co-pending application, Serial No. 559,011, filed January 13, 1956, for Clothes Treating Liquid Dispenser for Automatic Washing Machines now Patent No. 2,868,006, granted January 13, 1959, the present device including several forms of the attachment for use in conjunction with automatic washers of the tumbler type which are equipped with a clothes washing basket or tub which retates about a horizontal or substantially horizontal axis and which is provided with a reversible motor for rotating the tub or basket in one direction during a portion of the washing operation and rotating it in another direction during other portions of the complete stages or cycles of the machine.

The shortcomings of the presently commercially avail able automatic washing machines include the absence of any provision for automatically dispensing additives to the machine after the final washing action and prior to the final spin drying. In other words, after the 'dirty wash water has been spun from the clothes by a high speed rotational movement which employs the centrifugal force to extract the water, there is no provision for adding any clothes treating or water treating material to the machine during the subsequent rinse cycle or subsequent rinse cycles. This is objectionable, inasmuch as it is quite frequent that the use of such additives is desired, and in some instances the use of such additives is absolutely necessary for proper rinse action and for optimum treatment of the clothes due to hard water conditions or conditions under which bleach, bluings or other additives are desired. In order to make use of these additives, the housewife or other person in attendance to the machine must necessarily manually add the material to the washing machine at the proper time. In the tumbler type washers where the tub is rotatable about a horizontal axis, the addition of these materials must be at the proper time during the cycle of operation, inasmuch as it is impossible to open the entrance door to the washing compartment when the machine is filled with or par- Accordingly, the primary object of the present invention is to provide an attachment for automatic ,washing machines of the tumbler type that is constructed for automatically dispensing a desired quantity of treating material into the washing tub of the machine at the proper time, thus forming a completely automatic operation.

The present invention is incorporated in the tumbler; type washing machine having a reversible drive motor:

which may rotate the tub in a clockwise or counterclockwise direction and requires the rotation during the washing cycle and the high speed spinning out of the wash water to be in one direction or a clockwise direction, while the slow rotation during the rinsing cycle be in the counterclockwise direction. I v

A further object of the present invention is to provide an attachment in accordance with the preceding objects which is extremely simple in construction, easy to attach, foolproof in operation, provided with no moving partsor adjustments, adapted for use with various machine construction, and-relatively inexpensive to manu facture.

These together with other 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 bad to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Each form of the present invention is to be employed with the tumbler type washing machine in which the clothes washing .tub or basket is rotatable about substantially a horizontal axis, although the invention may also be employed with those Washing machines having the basket rotated about an inclined axis. The details of the washing machine are not illustrated and the manner of attaching the device of the. present invention to the washing machine may be any conventional fastening means, and that which is illustrated has been illust-rated merely for the purposes. of description with it being understood that any type of fastening mechanism may be employed. Or, in fact, the device may actually be formed as an integral part of the washing tub or basket. Also, it is pointed out that the present invention is employed with that type of washing machine having a reversible drive motor in which the rinse cycle rotates the tumbler basket or tub in a counterclockwise manner, while the washing cycle or cycles include the rotation of the tub in a clockwise manner, as designated by the various arrows in the various views. Reversible motors of this type are commercially available and may be substituted for unidirectional motors employed in existing washing machines with proper electrical hookup for automatically reversing rotation of the tub when the rinse cycle is reached. Details of the motor, the washing machine and the electrical hook-up form no part of the invention and are mentioned merely for the purpose of describing the invention.

Referring now specifically to Figures 1-5 of the drawings, the numeral generally designates the attachment of the present invention and represents the most simple adaptation thereof, which consists of a length of tubing formed in two concentric circles designated as an inner circle by the numeral 12 and an outer circle by the numeral 14. The inner and outer circles of the tube form one continuous tube, with the outer circle 14 being closed at its free end as designated by the numeral 16. The inner end of the outer tube 14 is offset inwardly as designated by numeral 18 and is integrally connected with the outer end of the inner circle or tube 12. The inner circle 12 then extends from the offset portion 18 within and against the inner surface of the outer tube 14- forming a nearly complete circle and end with an open end 20.

A filler opening 22 and a plug 24 therefor is located approximately diametrically opposed to the closed end 16 or offset portion 18, and the closure plug 24 must be employed for closing the opening after the material has been disposed in the attachment 10. During the insertion of the clothes treating material into the attachment 10, the filler hole 22 should be above the centerline of the device in order to give a reasonable capacity. If the hole 22 is at its lowest point, then it would be impossible to fill the device and place the plug 24 therein. Thus, the position of the filler opening or hole 22 will determine the capacity of the device and will also determine whether the material will lie in the open or closed end of the outer circle 14 or partially in each. It may also be seen that the material may lie partly in inner tube or circle 12, but if the device is not filled much above halfway, the material will not run out of open end 20.

By way of illustrating mounting means for the device, inwardly extending radial arms 26 are provided on the inner circle 12, with a central opening 28 receiving a stud 30 for securing the device on the wall 32 of the washer tub.

In operation of the device illustrated in Figures 1-5,

the attachment 10 is filled as described above and the clothes and soap are loaded into the machine and the machine fills and begin its rotation in a clockwise direction at slow speed. As the tub and the attachment continue to rotate clockwise, the effect is much the same as a screw, the material having a tendency to remain essentially at or near the closed end of outer tube 14, as illustrated generally in Figure 4. The machine then starts the spin cycle at a higher rate of speed in order to spin out the wash water. During this cycle, the speed is great enough to cause the material in the attachment to be held against the outer wall of outer tube 14 by centrifugal force. The material in the device does not escape through open end 20 during this high speed spinning. The spin then stops and the rinse water flows in in the usual manner. By use of a capacitor type motor or other means, the cycle timer reverses the direction of rotation to a counterclockwise rotation at slow speed. As illustrated in Figure 5, the opposite screw effect is now achieved in which this screw effect tends to lift the treating material into the inner tube 12 and out the open end 20 thereof substantially as illustrated in Figure 5. All of the material is not dispensed in the first revolution, but after several revolutions, the attachment 10 is entirely emptied. Thus, the present device provides a simple means for dispensing clothes treating material, whether it be liquid or other flowable material into the automatic washer at the proper time for dispensing into the rinse water. It is pointed out that the material is not dumped into the tub until such time as the tub has a portion of the rinse water therein, since the rotation during the rinsing cycle does not usually begin until a certain amount of rinse water has been admitted into the washing tub.

Referring now specifically to Figures 6-10 of the drawings, another form of the invention is generally designated by numeral 40. This form of the invention incorporates a pair of circular side plates 42* and 44 having a single continuous strip generally designated by the numeral 46 disposed therebetween. One end of the strip 46, which is designated by the numeral 48, is located at a point in spaced relation from the center of rotation of the attachment 40. From that point, the strip proceeds on a radius clockwise forming a semicircle, then angles outward rather sharply in a radial direction as designated by the numeral 50. This outwardly extending portion extends to a point approximately one-half again as far from the center as was the semicircular portion 48. Then the strip 46 extends on a radius clockwise forming nearly a complete circle and this portion of the strip is designated by numeral 52. The free end of the portion 52 angles inwardly sharply, as designated by numeral 54, and the strip thus ends near the juncture of the inner semicircle 48 and the angled portion 50, with the terminal end thereof being just short of touching inner semicircle 48, thus leaving an outlet opening designated by numeral 56.

In this construction, the plate 44 is provided with a central filler opening 58, while the plate 42 may be provided with supporting means for mounting the device on a fastener element 60 for mounting the device in predetermined relation to the rotatable washing tub 62.

In operation, the device being filled and the operation of the washing machine begins, the rotation of the tub is in a clockwise direction at low speed. It is pointed out that this form of the device should also be filled only approximately one-third full. As the device rotates in a clockwise direction, the fluid within is lifted from circle 52 into semicircle 48 by angled portion 50. As rotation is continued, fluid is poured back from semicircle 48 into circle 52. The process is repeated as long as the machine rotates slowly clockwise during the wash cycle. This is generally illustrated in Figure 8, and this is the general displacement of the fluid during both filling and initial slow rotation.

The machine then starts the spin cycle clockwise at high speed in order to spin out the wash water by centrifugal force. During this cycle, the fluid is held against the periphery of the dispenser by centrifugal force as shown in Figure 9. It remains in the dispenser because of the inturned end 54 on the portion 52 of strip 46. The spin then stops and the rinse water flows in in the usual manner and the fluid in the device again falls to the bottom, and depending on placement of the dispenser about its axis, from none to nearly one-half of the fluid may flow into the rinse water out through the discharge opening 56. By use of a capacitor type motor by other means, the cycle timer on the washer reverses the direction of rotation to counterclockwise at slow speed during the rinse cycle. This fluid then flows out of semicircle 48 around portion 52 and out opening 56 and, -again, all of the fluid may not flow out during the first revolution, but after several revolutions the dispenser is completely emptied. With this construction and by filling the device substantially one-third full, the filler plug may be omitted.

Referring now specifically to Figures 1115 of the drawings, the numeral 70 generally illustrates a still further modified form of the present invention that includes circular side plates 72 and 74, with the plates 72 and 74 being spaced by two strips 76 and 78. Each of the strips 76 and 78 are formed generally as a circle or cylinder, but lack appnoximately ten to twenty degrees of being a complete circle. One end of strip 76 lies within the circle formed by strip 78 near the inner surface thereof and diametrically opposed to the opening left by the incomplete closing of the circle formed by strip 78. The other end of strip 76 lies near the outer wall of strip 78 and is nearly diametrically opposed to the opening between the ends of the circle formed by strip 78. Similarly, strip '78 maintainsthe sarne relationship to the circle formed by strip 76, that is, one end within and one end without the circle formed by strip 76, with both ends thereof substantially diametrically opposed to the opening in the strip 76. This relationship is specifically shown in Figure 11, and the plates 72 and 74 are attached to strips 76 tially in the center thereof and the device is mounted substantially in the same way as the'device in Figure 7, by employing a fastening device 82 for mounting the same on the spinning tub or basket 84. It is pointed out that the substantially cylindrical strips 76 and 78 actually form two overlapping cups for receiving the treating material therein.

In operation, the device is filled to approximately onefourth to one-third full, as shown in Figure 13., and the washing machine is then loaded in the usual manner and the washer is started, and after it is filled with water begins its rotation in a clockwise direction at low speed. The device also rotates clockwise and the liquid or fluid contained in strip 76 will be poured into the strip 78 during rotation of the device in a clockwise manner. The spaced relation between the inner surface of strip 76 and one end of strip 78 will assure that all of the liquid will be poured from strip 76 into strip 78, and during the slow clockwise rotation thereof, the liquid is poured sequentially back and forth from the strips and the cups formed by the strips 76 and '78.

The machine then starts the spin cycle at a high rate of speed in .order to spin the water out of the clothes by centrifugal force, and during this spinning cycle the liquid in the dispenser is held against diametrically opposed ends of the dispenser at the two ends farthest from the axis of rotation, as clearly seen in Figure 14. It may be also seen in Figure 14 that the liquid is not necessarily equally divided between the two ends. The spinning action then stops and the rinse water flows in in the usual manner. The liquid in the dispenser falls tothe bottom ofwhichever strip it may be and,

and '78. The front. plate 74 is provided with a filler opening 80 substan-' depending on the position of the strips, part of the liquid may flow out of the dispenser into the rinse water as the spin stops. By use of a capacitor type motor or by other means the direction of rotation is reversed to a counterclockwise rotation at slow speed after .the spin cycle, and since part of the liquid still remains in the dispenser, it will be discharged from the outer end of whichever strip it may be contained in substantially as illustrated in Figure 15 during rotation in a counterclockwise direction. A part of the liquid may have been scooped into the other of the cups, but will be discharged therefrom during subsequent revolutions, whereby all of the fluid will be discharged from the dispenser into the rinse water.

Referring now specifically to Figures 16-19, another modified form of the invention is generally designated by the numeral and includes a pair of circular side plates 92 and 94. The plate 94 is provided with a filler opening 96 at its center and a cylindrical peripheral Wall 98 is provided between the plates 92 and 94, with the wall 98 being continuous.

' Disposed within the cylindrical container formed by walls 92, 94 and 98 is a tube 100 flared at its outer end 102 into a substantially enlarged cross sectional area as designated by numeral 104, thus forming substantially a scoop. At its inner end, the tube 100 is curved, as designated by numeral 106, so as to project through the side wall 94 of the container adjacent to or near the filler opening 96. The body of the tube 100 is curved away from the open end 104 in such a manner that the end portion 104 is substantially 90 degrees away from or spaced from the portion 106. In actual prac tice, there may be a multiplicity of the tubes, as may be deemed desirable, but a single tube is described for the purposes of illustration. The outwardly flared end 102 is disposed adjacent to the inner surface eral wall 98 and its sides are adjacent to the side plates 92 and 94 substantially as illustrated clearly in Figure 17.

In operation, the device again is filled approximately one-third and the washing machine started in the usual manner, with the initial rotation being a slow speed clockwise direction. The device also rotates in a clockwise manncr wherein the fluid will flow around and over the tube 100, and by the force of gravity the fluid is held in the bottom of the container. Any of the fluid which may rise into tube 100 as the open end 104 passes below the surface of the fluid is effectively poured back into the container as the open end 104 rises above the surface of the fluid in its clockwise rotation. This action is generally suggested in Figure 18.

The machine then starts the spin cycle at a high rate of speed in order to spinthe water out of the clothes by centrifugal force. During this cycle, the liquid in the dispenser is held against the periphery of the dispenser by centrifugal force. The spin then stops and the rinse water flows in in the usual manner, and the fluid in the dispenser again falls to the bottom. By use of a capacitor type motor or by other means, the cycle timer reverses the direction of rotation to a counterclockwise rotation at slow speed during the rinse cycle.

As scoop end 104 passes below the surface of the fluid, the fluid enters the open end 104 and rises to a height equal to the level of the fluid in the dispenser.-

As the counterclockwise rotation continues, the fluid starts to run out the open end 106 of the tube 100, substantially as illustrated in Figure 19. As soon as the tube is at a position as shown in Figure 19, the fluid has essentially all run out of the tube, and this scooping and emptying process continues until the fluid is entirely emptied from the dispenser into the rinse water.

In each form of the invention, the fluid is maintained in the dispenser during the washing action or the slow speed clockwise direction and also is held in the dispenser during the high speed extraction of the wash water and of the periph is subsequently discharged into the washing machine when the device is rotated in a counterclockwise manner due to rotation of the tub in the counterclockwise direction during the rinsing cycle. In each instance, the device may be constructed of any well known material and may be economically constructed of plastic, metal or the like. In each instance, no moving parts are provided and also each device may be supported in any suitable manner on the washing tub so that the axis of rotation thereof is coincident with the axis of rotation of the tub.

It is pointed out that commercially available automatic washers are provided with motors which are reversible by switching two wires and reverse or counterclockwise rotation of the tub or basket may be accomplished by a timer switch specifically adapted for this purpose.

The foregoing is considered as illustrative only of the 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 described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
