Oct. 22, 1963 c. A. COBB FLUENT MATERIAL DISPENSER FOR A WASHING MACHINE Filed March 4, 1963 INVENTOR CL' 'Uw Q. C05 Qww,
United States Patent O 3,107,512 FLUENT MATEREAL DISPENSER EUR A WASHING MACE Clifton A. Cobb, St. Joseph, Mich., assigner to Whirlpool Corporation, a corporation of Delaware Filed Mar. 4, 1963, Ser. No. 262,547 6 Claims. (Cl. oli-17) This invention relates to a fluent material dispensing device for a washing machine spin basket.
During the laundering of clothes it is frequently necessary to add ingredient-s such as softeners or conditioners or even detergents to the washing Iliquid in an automatic washing machine spin basket. Thus, where the washing machine goes through several cycles including rinsing it is frequently desirable to add -a water softening compound or additive in order to reduce scum formation, particularly in the rinse water.
The dispensing device of this invention utilizes the spinning of the basket itself to condition the dispensing device for gravitational discharge of a fluent material upon cessation of rotation of the basket.
`One of the features of this invention therefore is to provide an improved iluent material dispensing device for a washing machine spin basket in which means operated by the spinning of the basket opens a closure to a container for the material while retaining the material in the container as the spinning approaches a maximum but with the container arranged to permit ilow of material therefrom when the basket approaches and/or is at a state of rest.
Other features and advantages of the invention will be apparent from the following description of one embodiment thereof taken in conjunction with the accompanying drawings. `Of the drawings:
FIGURE l is a side elevational view partially broken away of an automatic washing machine having a dispensing device embodying the invention.
FIGURE 2 is 4a horizontal sectional view taken substantially along line 2 2 of FIGURE l.
FIGURE 3 is a fragmentary plan view partially broken away for clarity of illustration of the removable holder for holding the dispensing container of the dispensing device.
`FIGURE 4 is a view similar 4to FIGURE 3 but showing the container in position.
FIGURE 5 is a front elevational view of the assembly of FIGURE 4.
FIGURE 6 is a Isectional view taken substantailly along line `6--6 of FIGURE 5.
FIGURE 7 is a View similar to FIGURE 6 but showing the dispensing container in retracted position under the influences of the spinning forces.
In the embodiment of the drawings the dispensing device Itl is shown associated with the spin basket or vessel '11 of an automatic washing machine having the usual outer casing A12, rear control panel 13, agitator 14 driven by a motor 15 and supporting feet lo.
During the operation of the washing machine the spin basket 1-1 which contains the usual perforations (not shown) is spun at high speed during a centrifuging cycle within its imperforate tub y17 in order to extract liquid such las a washing solution from the clothes-within the basket 1.1. While not shown in detail basket 11 is rotatably supponted and driven by a drive tube having driving connections to motor 15 all Iof which drive connections may hereinafter be referred to as the -drive means for basket 11. In the automatic washing machine described the liquid is contained in both the basket 11 and tub 17. The clothes themselves are contained within the spin basket 11. Then, during the extraction the BQIS-lz Patented Get. 22, 1953 icc basket is spun at a centrifuging speed approaching, for example, 500 r.p.m.
The dispensing device 10 of this invention is constructed to utilize the spinning of the basket 'l1 to precondition Ithe dispensing device lt) for gravitational discharging iiuent material 1S into the basket 11 as the basket 11 drops below the centrifuging speed capable of retaining material 18 within device 10. The spin basket contains the usual i-nturned rim i9 and held on this rim is a holder Ztl.
The holder 20 includes a bottom plate section 21 that is sloped downwardy and forwardly toward the center of fthe basket l1 and which has a lower edge 22 adapted to -bear against the inner surface of the basket 11. The front edge 23 of the section is thus at a lower elevation than the rear edge 22. The front edge Z3 is provided with a central projecting tongue 24 having a front edge 25 defining a relatively stationary abutment surface. The holder is provided with sides 26 and a top 27 forming an enclosure for retaining the fluent material container 28. As can be Iseen in FIGUR-ES 3 and 6, the sides 26 and top 27 are narrower than the bottom plate section 21 so that the sides and top constitute an enclosing ring spaced forwardly of the adjacent portion of the spin basket rl1. The holder 20 which provides a stationary reaction member including abutment surface 25 is removably clamped in place by means of an integral resilient Vanchor clip 29 `forming a part of the top 27 and shaped complementarily to the rim 119 to be held securely on this rim. The holder 39 is preferably made of a molded plastic so that it can be snapped into position by means of the clip 2.9 and can be just as easily removed.
The container 28 is in the form of a relatively dat elongated bottle having a circular neck 30 on which is resiliently retained a cap 31. This cap is attached to the container preferably at the front by means of a flexible strip 32 of plastic material having one end attached to the cap 31 and the other end attached to the container 23 at the `front portion 'thereof so as to be clear of 'the holder Ztl. Other hinged constructions may readily be xadapted for retaining cap 32 upon actuation of this dispenser device. The cap 31 is provided with -a rim 33 and an inwardly extending annular tongue 34 so that the cap may be snapped into and out of position on the container.
In order to retain the Vcontainer Z8 within the holder 2t) when the spin basket 11 is at rest, the rear sides of the container lare enlarged, as indicated at 35, with these enlargements abutting against the rear edges of the sides 26 when the container is in posi-tion. Because of the resilient nature of the plastic of the holder `and because the top 27 is normally spaced above the top `of the container 28 the enlarged projections 35 may be used to `snap the container into and out of position within the holder.
FGURES 4, 5 and 6 illustrate the relative position of the container 23 when the spin basket is at rest. In this position the enlarged projections 35 are against the rear edges of 'the sides 26, the container 28 is in -a forward position on the sloped bottom plate section Z1 and the bottom of the annular rim 33 of the cap 3'1 is against the forward edge 2S of the tongue 24. iIn this position the iluent material 18, here shown as a usual water conditioning or additive compound in iluid form, is retained in the container 2S by means of the cap 31. Various types of fluid, powder, pellet or granular additives for treatment of the solution or the fabrics themselves may be used in this dispenser device.
During the spinning portion of the cycle centrifugal force on the container 2S yas the speed increases toward a maximum causes the container 28 to slide upwardly and rearwardly on the inclined bottom plate section 21 of the holder 20 in a transverse movement relative to container 28. As soon Ias the centrifugal force becomes sulcient the forward abutting edge 25 of the tongue 24 engaging the bottom of the cap rim 33 snaps the cap 31 from the neck 39 of the container. At this point, however, centrifugal force on the contents of the container is suiiicient to retain the tluent ymaterial within the container, as shown in FIGURE 7. However, as the spinning cycle terminates and the basket slows down, there is a point reached in the speed of rotation where centrifugal force is not suiiicent to retain the material 18 within the container at which time the iluent contents ow by gravity out of the container indicated by the dotted lines at 36.
As can be seen from the above description the dispensing device of this invention is a separate device that can `be easily installed as by snapping on the rim of an ordinary spin basket of an automatic washing machine. The device is so constructed that the iluent material is retained in the dispensing device until the spin basket is spun in a spinning cycle at which time the closure for the container for the fluent material is automatically opened. However, the tluent material is not fed from the container into the interior of the spinning basket at this time as the speed also causes the material to be retained in the container. However, as soon as the spinning -slows down from its maximum, gravity on the iiuent material overcomes the centrifugal effect and the material flows from the container into the spin basket where it is available in the next liquid cycle.
Having described my invention as related to the embodiment shown in the accompanying drawings, it is my intention that the invention be not limited by any of the details of description, unless otherwise specied, but rather be construed broadly within its spirit and scope as set out in the accompanying claims.
