Description

Patented Sept. 21, 1954 UNITED STATES PATENT OFFICE 13 Claims.

The present invention relates to a rinsing mechanism for wringers.

More specifically, the invention relates to a mechanism that may be embodied into a wringer structure of a washing machine for the purpose of providing rinse water adjacent the wringer rolls at a point where the wash enters or leaves such rolls.

By removing the soap, scum and other foreign matter which clingsto clothes before they arepassed through a wringer, it is possible to obtain whiter and cleaner clothes particularly by eliminating such foreign matter.

It is one of the objects of the present invention to provide a clothes rinsing structure by supplying rinse water to a hollow pressure release bar thus providing a convenient arrangement for distributing rinse water to the clothes that pass through the wringer. i It is another object of the present invention to provide complementary clothes rinsing mechanism by directingrinse water to a hollowed-portion of the drain board structure of the wringer, thus also establishing a rinse from beneath the clothing as the latter garments pass through "such wringer.

It is another object of the present invention to provide a suitable means for distributing rinse water to the pressure release bar or drain board of thewringer and to introduce a valving b arrangement for cutting off the entire rinsing water or for selectively allowing the rinse water to pass through the pressure release bar or throughthe drain board of the wringer, depending upon conditions of operation.

It is a further object of the present invention to provide auxiliary manifold arrangements which can be attached to the release bar of the wringer and also to the drain board thereof respectively which may be used as accessory features for supplying rinse water in the path of the clothes that pass through the wringer.

It is a furtherobject of the present invention to provide operable mechanism that is responsive to. the bodily movement of the wringer rolls which is directly connected for opening and closing the water supply valve so as to open the valve for the passageof rinsewater whenever a piece of clothing enters the wringer rolls. Conversely, the rinse water may be shut ofi as soon as the rolls come-together in their normal contacted positions.

Other objects and advantages relating to the present invention shall hereinafter appearin the following detailed description having ref- 2 erence to the accompanying drawingforming a part of this specification.

Fig. 8 is a diagrammatic illustration of a conventional wringer attachment illustrating the use of a valve means for the rinse water which is rendered operative through the relative movement of the wringer rolls.

Fig. 1 shows a conventional washing machine having the tub I supported above the operating mechanism compartment 2 with a laterally disposed wringer post 3 terminating in a head 4 that supports a wringer 5 by means of the wringer housing 6 in a conventional manner. The wringer 5 is of the swingableconstruction that may be limited in any convenient manner as by means of a pin 1 connected with a portion of the wringer post 3 which operates within a limiting shouldered slot 8 that rotates directly with the wringer housing 6.

The wringer 5 is also of a conventional type which includes suitable operative mechanism within the housing 6 that is driven through the interior of the wringer post 3 from operating mechanism confined within the housing 2. The. wringer rolls are shown at 9 and Ill arrangedto receive the washed clothes from within the washing machne tub I over a suitable drain board H and beneath the head l2 of the wringer which is flanked by a pressure release bar IS.

The pressure release bar I3 is usually duplicated on the opposite side of the wringer and the drain board H is likewise so duplicated in conventional wringer structures.

A water supply standard or pipe M can be secured adjacent the wringer post 3 to receive an external supply of water through a hose such as It, and water passes through a flexible hose l8 that is connected between the head end ll of the fixed water supply pipe l4 and a valve structure l8.

The valve structure It may be of any suitable type having a main valve it that can be opened and closed by means of a valve handle 20. Valve [9 is provided with a manifold extension 2!- with valve control outlets 22 and 23 arranged for receiving flexible couplings Or hoses such as 24 and 25. The valve manifold Zl may also be provided with a. pair'of sirni'lar' valve controlled outlets on th opposite side thereof which are here shown as closed by

plugs

26 and 2?. By removingplugs 2B and 2?", suitable hoses such as 28 and 29 may be also secured to the manifold for supplying a similar pres-sure release bar such as ['3 and an identical drain board such as H at the opposite side of the wringer. As shown. in Fig. 2, the pressure release bar i3 is hollow to provide an interior duct 30 from which a plurality ofdrilled openings tl may be positioned to direct rinse water downwardly upon the clothes and adjacent the wringer rolls 9 and; H The hose 24 connects by means or a suitable nippl 32 with one. end or the pressure. release bar 13 to thus conductrinse water from the water supply system and valve arrangement into the pressure release bar [3.

InFig, 3,, the drain. board ll isv provided with a manifold section 33 providing a duct 34 havin a plurality of. drilled openings 35 connected therewith, for directing water upwardly beneath the clothes. which pass. through the wringer rolls. The hose 25 connects by means of a suitable nipple 36 with the manifold 33 to supply rinse water through the valving system and into the drain board clothesrinsing.structure.

With this arrangement, it is possible to provide a rinsing means which is positioned conveniently with respect to the rolls ofthe wringer and into the most convenient position for access to the clothing. that is passed through the wringer. Furthermore, the pressure release bar of the wringer is herein utilized to provide a dual function and the drain board H is also so utilized. By having both or the

valves

31 and 38 of the manifold open and by opening the main valve 253, rinse water enters the entire system thorugh the hose i and passes on to the pressure release bar and drain board for rinsing the clothes above and below respectively. Valves 31 and 38 may be employed to out off the water to either one of the units comprising the pressure release bar l3 or the drain board H.

Figs. 4- and 5 show a manifold attachment 39 secured by suitable straps such as 4 3 and M to a pressure release bar lie and rinse water is brought through a flexible hose 240: from. the valve arrangement in as in the preferred construction. Th manifold 39 has an interior duct 39a. and a. plurality of water supply openings am leading therefrom. I

Figs. 6 and 7 illustrate the use of a. relatively flat manifold 42 secured at 43 and 44, to the sur-. face of the drain board Ila and water is supplied to this manifold 42 through a flexible hose 25a that is also connected with the valving system.

In the rinsin arrangement illustrated in Fig. 1, and in Figs. 4 and 6 respectively, the use of flexible hoses such as z t-25a and 25-25:; will permit the free operation of the pressure release bar respectively and will also establish a means for connecting a rinse system with a drain board which may be movably mounted with respect to the wringer. Furthermore the use of a flexible coupling such as it will permit swinging of the wringer 5 without interferring with the supply water system.

In Fig. 8,. one end of the wringer 5 is diagrammatically illustrated showing the interior thereof and the relatively movable wringer rolls 9 and Lil. Roll 9 ismovably guided by means of a bearing block 59 between suitable guides such as 5| and E2, while the wringer roll I0 is usually fixed by means of a bearing block 53 secured in place between guides 5| and 52.

This construction utilizes a similar valving arrangement iSaas. inthe Fig. 1- construction having a manifiold Hiawhich can be opened: and closedby an operating lever- 20a. Water is supplied: throngh' a flexible hose or coupling lea to the valve Him for entry into a manifold 2|.a. However, the valve [9a is opened by means. of the relative movement of the wringer rolls so that the rinse waterv is normally shut off until a. piece of clothing enters. between the rolls to separate such rolls as Si and Ill, whereupon. the rinse water will automatically be supplied to the pressure release bar structure or to the drain board structure. This is accomplished by the use of a cable: in the form of a flexible wire such as 54 which passes through a suitable. thimble 55 secured to one-of the vertical guide members 5| and is secured to any oneof the movable portionsv of the movable roll 9 such asto-thebearing 5! where the cable is attached at 56. The other end; 51 ofthe cable may.- be attached in any one or a number of positions in. the openings 55 in the lever 2%. A tension spring 59 normally maintains the lever 26a; in a position to clos the valve Ito, and a pu11 on the cable 54 responsiveto the bodily movement of the wringer roll 9' will open the valve I9 to supply rinse water to the structures hercinbeioredescribed. It should also be noted that the lever 2'da may be operated by hand since the slack in the cable will permit. such action. Considerable saving of water can. be automatically accomplished through. the use of a wringer and rinsing structure substantially as illustrated. in Fig, 8-

While the foregoing description; has been directed to preferred embodiments of. the. invention, it is to. be understood. that certain changes may be made in the details of construction, com.- bination and. arrangement or, parts,. and that such changes are contemplated, without departing from the spirit and. scope of the-invention. as

claimed. V

For example pipe l4 and hose [61 can besuitably installed within the post. 3' and wringer base to connect with a valve I 8 mounted for use within the wringer head 6 with only the stems of the

valves

20, 31 and 38 extendin outwardly'of the head. for convenient use. by the operator. Hose couplings such as 24 and 25 may likewise be concealed within the wringer head for connection with the release bar l3- andjdrain board H' if so desired.
