INVENTOR. OWL/L jlZ Cbofwsw United States Patent C) 2,887,863 RINSE WRIN GER CONSTRUCTION Orin N. Cooper, Garwin, Iowa Application May 6, 1955, Serial No. 506,515 6 Claims. (Cl. 68-22) wringer, all as more completely set forth and described in my Patent No. 2,689,471, issued September 21, 1954. The invention also comprises an improvement in the clothes rinsing meansfor wringers as set forth in my copending application Serial No. 259,741, filed on Decem her 4, 1951, 1956. g

When rinse water from an external source is applied to garments as they enter the wringer rolls such additional and excess water must be disposed of and kept from draining backinto the clothes washing tub. Some diversionis not entirely objectionable, but since the rinse water is normally cold water this water would lower the tub water temperature. At the same time the tub water level will be raised above the normal high water level suited for the washing operation as recommended by the washing machine manufacturer.

' Onefof the objects of this invention is to provide a now Patent No. 2,748,586, dated June 5,

drain board for a wringer having a predetermined configuration and contour to divert wringer rinse water toward and, into a rinse water drain area and away from flowage into the tub of the washing machine.

. Another object ofthe present invention is to provide a drain board for use with a rinse wringer, arrangement and wherein said drain board includes a forward raised ridge or weir portion disposed to. terminate in vertical spaced relation above a horizontal plane coincident with the-line'of Jtangency of the wringer rolls. With this provision'the garments are held in suspended relation above the drain surface of the drain board stretching between the raised ridge and the wringer rolls.

@Ahstillfurther object is. to position a rinse water dischargelarea as a par-tofthe drain board that is located.

toward the wringer rolls and well below-both the forward raised edge ofthefboard and the level of the line of tangencyofthe wringer rolls. 7 j

:"As another object-of the invention the raised ridgeon the'drain'board terminates in .a fairly sharp edge to provide a squeegeeorwash water releasing action to return a considerable amount of the wash water in the clothes into th has the clothes are passing over the drain board edge and on the "way to the wringer rolls. Thus less wash water i carriedover with the clothing during the wringer f'hnctidnandbetter rinsing results. 1 Q

other objects liavelto do with such factors as the use of a reverse slope 'on the drain board to divert water v with structural portions 'the clothes path to rinse the toward the wringer rolls toward drain means and slope also prevents water from collecting or standing 1 upon any portion of the board drain surfaces; the, pro vision of a modified raised edge on the forward portion of the drain board to provide a squeegee edge arranged.. substantially at right angles to the lifting pull of the gar,-: ments going to the wringer; and also the provision of undercut portions at the drain board raised edge and on, the wringer roll side thereof to further counteract possible overflow or return of garment water and rinse water back into the tub. g i Certain other objects relating to novel features ofthe present invention will hereinafter become apparent from} the following detailed description having reference to the accompanying drawings illustrating the inventionand forming a part of this specification;

In the drawings: r Fig. l is a side elevation view of the upper part of a washing machine having a wringer embodying the present invention, the wringer being shown in operative position and as it appears from the clothes receiving side thereof; Fig. 2 is a fragmentary vertical cross sectional view taken transversely through the wringer and wringer rolls and substantially as viewed along the plane of the line 22 in Fig. 1; e Fig. 3 is a plan view of the drain board of the present invention as it appears when removed from-the wringer frame; and p Fig. 4 is a fragmentary sectional view of a forward section of the drain board construction of this invention but illustrating a modified design of a raised forward; edge or weir. 1 Referring now to Fig. l, the washing machine lha's' a tub 2 including a connected wringer post 3 to carry the base fixture 4 of a wringer 5 that incorporates the drain board 6 of the present improved design. The wringer 5 carries upper andlower wringer rolls 7 and 8 respec'- tively suitably mounted in the wringer frame 9, with the operating handle 10 being provided to control the operas tion of the wringer in the conventional manner. The wringer also carries suitable pressure release bars 11 and 12, the bar 11 being hollow as at 13 to provide a, conduit along its length and also is provided with rows of, small ports or openings 14 and 15 along the lower edge' of the'bar to establish a clean water spray source above garments as they are fed into the wringer rolls 7 and 8. i The drain board 6 comprises a vertical wall or apron 16 contiguously blending into end walls or aprons 17 and i 18 with the apron 16 terminating with a raised forwardly disposed weir or ridge. 19 that leads between the up wardly positioned and upsloping end barriers 20 and I of the drain board 6. The balance ofthe drain board' 6 includes a trough 22 defined by the upper surface of the" wall or bafile 23 and the inner surface of the connecting wall structures comprising the weir 19 and barriersj20 f and 21. p j l The wringer side or face 24 of the drain board 6 has

suitable extensions

25 and 26 adapted for securement of the wringer frame 9 to securely hold and mount the drain board with its face24 flush against the adjacent wringer face 27. p p The drain board 6 is also provided with a depending rearwardly sloping wall 28 including a heavier body section 29 formed between wall 23 and wall 28 that is hollowed out at 30 to provide a rinse water conduit. Rows of rinse

water discharge ports

31 and 32 communicate with conduit 30 and these ports are positioned to direct a, rinse spray against the underside of a garment such as when the latter is fed through thewringer rolls 7 land 8. j Rinse water may be supplied to the pressure release bar" 3 rinse water conduit 13 and to the drain board rinse water conduit 30 through a flexible hose 34 connected with a suitable cold water supply and being joined with a nipple 35. secured to the inlet leg 36' of a valve 37 that carries a valve wheel 38' to open or close the valve 37. Branch outlet nipples 39 and 40 each have

flexible hose sections

41 and 42 respectively which connect with inlet nipples 43"and 44carried by the pressure release bar 11 and drain boardfi to communicate with conduits 13' and 30' respectively. Thus rinse water can be selectively turned on or off as required and the quantity of water may also be regulated for different conditions of operation or as may be desired by the operator.

A drain pan 45 is mounted in the wringer frame 9 and is fitted to the cavity of the wringer beneath the wringer rolls 7 and 8; The pan has a discharge nipple 45 to which a drain hose 47 is secured, the hose 47 providing suitable means for the disposal of the wringer water to attain mm a pumpor' pump connection if that is feasible and desirable.

The forward top edge of the pan 45' is provided with an offset flange: or" rim 48 shaped to receive the depending'lip 49 that is part of the structure of the wall 28 of the drain board 6. The rear top edge of the pan 45 also has an offsetflange or rim 50' to accommodate the depending lip. 51 that is a part of the depending wall 52 of the rear or clothes discharge board 53' that is secured to the rear face or side 54 ofthe wringer frame 9. The rear discharge board presents the garment guiding trough 55 as outlined by the contour and shape of the wall 56 and the drop-01f apron 57.

Referring back to Fig. 2, it should be noted that the clothing. is fed to the wringer rolls 7 and 8 along a down slope. and this is emphasized bythe general angularity of the garment 33 and also by the. slope of the dot and dash line 58; This arrangement, therefore, causes rinse Water and extracted water to flow over the garment inthe generaldirection of the wringer rolls and about the garment to drain oifofthe wall 23 and out of the trough 22 over the surface of'wall 28 and into the drain pan 45. Simultaneously, the sharp corner 59 on the top edge of the weir 19 functions to extract a good portion of. wash water from the garment and which water drains back into the tube 2.

The trough wall 23 slopes down. as shown in Fig. 2, and from a level about coincidentwith the dot and dash line 60, which indicates a horizontal'plane coincident with the tangency of the rolls, and to a level where the rinse ports 31' and 32 are located. The object is to keep the garments from riding on the trough. surface to promote free uninterrupted flow of extracted and rinse water and to prevent mufiling or valving of the rinse water ports 31' and 32 which action would. interfere with the desirable and effici'ent garment penetration of the rinse water streams or sprays.

I'n Fig. 4, a modified construction of drain board 6a incorporates a different form of weir structure 61 wherein the apron 16a terminates with a horizontally disposed wash water extracting edge 62 under a generally curved garment guiding ridge or crown 63. The trough side of the crown 63 is undercut at 64 to provide a water return well or deflecting means that can be extended about the entire trough area of the drain board and up to the wringer frame face 27. One or more notches 65 may be provided in the long. direction ofthe crown. as a further means of retaining and rediverting some of the wash water from a garment back into the tub.
