WASHING AND WRINGING MACHINE.

Application filed March 1, 1924. Serial No. 696,318.

This invention relates to laundry apparatus, and more particularly to a combined clothes washing and wringing machine, for household use.

Among the objects of the invention are; to provide a washing machine having inn proved means for producing etfective. agitation of the water and clothes, and to provide two compartments in which clothes of different grades or kinds may be simultaneously washed; to provide means in the nature of a press, built into the'machine, and in which the clothes may be placed and subjected to pressure to squeeze the water out' of them; to provide improved means for causing circulation of the water from one part. of the washingmachiue to anotheri and to provide means whereby, whe.u desired, the continued operation of the machine may be caused to discharge the water therefrom and force it to a higher level, as, for example, through a llOfP, into a sink.

\Vith the above and other objects in view. and to generally improve the efiiciency and simplify the contraction of such apparatus, my invention consists in the arrangen'ient and combination of parts hereinafter descrihed and claimed. and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of the complete machine, parts being broken away;

Figure 2 is a vertical, central section therethrough, subitantially on the line 2-2 of Figure 1;

Figure 3 is a horizontal section on the line 3 3 of Figure 2;

Figure 4 is a side elevation of the lower part of the supporting pedestal and brace, this view being taken in a plane at right angles to that. of Figure 1, and parts being broken away; I

Figure 5 is a fragmentary transverse section through part of the reversing mechanism shown in Figures 1, 3 and 4;

Figure (3 is a horizontal section on the line 6() of Figure 2;

Figure 7 is a horizontal section substantially on the line 7-7 of Figure 9, taken through the top or cover of my improved press cylinder and showing the locking nzeaus therefor;

Figure 8 is a plan view of such top or cover; and V Figure 9 is a vertical section on the line J 9 of Figure 8.

Referring to the drawings in detail, my

improved combined washing and wringing machine comprises a suitable base 1, preferably circular in shape, as shown in Figure 3, and supported on suitable rollers or casters 2. Extending upwardly from the base is a relatively large hollow column or pedestal 3, the base and pedestal being preferably t'ormed integral, as by casting. At the top of the iedestal 3 is a horizontal plate or table 4, winch extends partially-over the interior of the pedestal, as indicated at 4".

Asecoud plate 5, of similar size and shape, overlies the plate 4, and carries, at its center, a vertically extending cylinder 6, which passes through the plate 4 and is disposed centrally of the column or pedestal 3.

'lhe clothes container comprises a suitable tub or receptacle 8, preferably formed of sheet metal and cylindrical in shape, the bottom part of such tub or receptacle being interposed between the two plates 4 and 5, as shown in Figure 2, and clamped in posi tion by means of a series of bolts 7. It will be noted that the 'sheet metal preferably extends between the plates 4 and 5, approximately-up to the cylinder 6 so that the bolts 7 pass through the same. From the above, it will be obvious that the cylinder 6, plates 4 and 5, and tub 8, are all united with the pedestal 3, to form a fixed, rigid structure.

Also, carried by the plate 5 and extendingupwardly therefrom, centrally of the tub or receptacle 8, is another and larger cylinder l2, provided with numbers of perforations 13, distributed throughout the walls thereof from the top to the bottom. The top of the cylinder 12 terminates slightly below the upper edge of the tub 8, and the upper .end of the tub or receptacle is closed by means of a lid or cover 9. also preferably formed of sheet metal, and provided with a flange which fits into the upper end of the tub in a well known manner, the upper edge of the tub being preferably beaded, as indicated at S. A pair of p0ckets or depressions 10, having bars 11 extending across the same. are provided in the cover 9. to constitute handles, by means of which the cover may be removed. It will be noted that this cover extends entirely across the top of cylinder l2. and conceals the same. so that such cylinder is com pletely housed within the tub or receptacle 8. The t \'lil'ltlcl' 12. which must necessarily be of strong construction, is preferably formed of cast metal, and is rovided with a rigid closure at its upper en such closure being shown in detail in Figures 7, 8 and 9. eferring to these figures, as well as to Figure 2, it will be seen that the closure comprises a circular dish-shaped member 14, having an upstanding flange 14" provided at its outer edge with a radially extending flange 14", which is adapted to seat upon the top of the cylinder. Enclosed within the member 14 and rotatably mounted upon a central screw 16, set therein, is a disk 15, the upper surface of which is preferably. flush with the upper edge of the flange 14, as shown in Figure 9. By means of cooperating bosses, formed on the member 1a and disk 15, these members are spaced apart, as shown in Figure 9, and in this space are mounted a plurality of latches 17, best shown in Figure 7.. Each of these latches is pivotally mounted eccentrically of the member 14 upon a screw 18, and the outer end of each latch is adapted to project, when in one position, through openings 14, formed in the flange 1 1. This is indicated by dotted lines in Figure 7. \Vhen, however, the latches are swung to full line position, they are completely housed within the contour of the member 1-1. In order to swing thelatches from full line to dotted line position, or vice versa, each is provided with a slot 19, in which works a pin 20, projecting downwardly from the lower face of the disk 15. Thus, when said disk is oscillated, the latches will be shifted, as is obvious. \Vith the latches in the full line position, the cover or closure is placed in the mouth, or upper end of the cylinder, as shown in Figure 2, and then, whenrthe disk 15 is moved, so as to shift the latches to the position indicated in dotted lines in Figure 7, these latches are caused to project from the periphery of the closure and to engage in slots formed in the walls of the cylinder 12, thus firmly and rigidly locking the closure to the cylinder.

As clearly shown in Figures 2 and G, the cylinder 12 centrally mounted within the tub 8, forms an annular space or washing chamber, in which the clothes are contained. In order to efi'ectively wash the clothes, this chamber is provided with suitable rubbing elements, the construction of which forms an important part of my invention. Inner and outer rubbing elements are provided, each comprising a series of vertically extending parallel wooden rods or bars, preferably circular in cross section. The outer series of bars is designated at 21 and constitutes a lining for the walls of the tub 8, while the inner series of bars is designated at 22, and constitutes a lining around the walls of the cylinder 12. The bars of each series are held together by being strung or threaded upon wire hoops 23. Furthernoted that the bars 22 of the inner series are spaced apart, at points opposite the perforations 13, in the wall of the cylinder 12, so as to permit jets of water, issuing from these perforations, to pass freely between them.

The real or fixed bottom of the tub 8 consists of the plate 5, and associated parts, but above and spaced from this bottom is a false, movable bottom, consisting of an annular plate 2 which surrounds the cylinder 12. This'plafe 24 is preferably perforated, as indicated at 25 in Figure 6, and is rigidly secured by means of screws 26, to an annular gear 26, mounted on ball bearings 26" (see Figure 2). Carried'by the plate 24:, and projecting upwardly therefrom into the annular space, between the cylinder 12 and walls of the tub 8, are two or more brackets 01' plates 27, preferably perforated, as shown, and designed to engage and move the mass of clothes.

\Vorking within the cylinder 12 is a piston 28, preferably having a rubber cushion or face 29, secured to the upper side thereof. This piston is carried by a hollow piston rod or plunger 30, which, in turn, carries at its lower end a second and smaller piston 31, which works snugly within the cylinder 6. A vertical screw shaft 32 is mounted centrally within the cylinder (3, and engages a threaded opening in the piston 31, so that. as said screw shaft revolves, the piston 31, together with the plunger 30 and piston 28. is caused to move upwardly or downwardly, depending upon the direction of rotation of the screw shaft. In order to prevent the pistons and plunger from rotating with the screw shaft, a spline in the nature ofa rod 33 is provided within the cylinder 12. such spline engaging a notch 34 in the piston 28.

The lower end of the screw shaft 32 is rigidly secured to a clutch disk 35, and the disk and shaft are supported by means of thrust bearings 38. resting upon a compression spring 36, enclosed within a housing 37, secured to the base 1. The shaft is also journaled on ball bearings 39, mounted in the lower end of the cylinder 6. and above these bearings is a stuffing box 40, to prevent leakage of water. This stuliing box is preferably in the nature of a closed chamber having a small pipe 41, extending therefrom through the wall of the pedestal 3. as shown in Figure 3. Suitable plastic material is forced under pressure through this pipe and into the stuffing box to fill the same, as indicated in Figure 2,

A second clutch member or friction disk 42, is in contact with and supported by the til! cated in the space between the lixed clutch member 35. the friction disk 42 being secured to the lower face of a horizontal- 1y disposed bevel gear 423. loosely journaled upon the screw shaft 32.

Beveled pinions 4t and 4.3 me h with the. beveled gear -13. at diametrically opposite points thereof. these pinions being seemed to stub shafts 4t; and 47. respectivclv. joun lulled in the walls of the pedestal and carrying at their outer ends belt pulleys ls and 49, respectively. ()n the end of the shaft. 4?, beyond the pulley 49. is secured a small beveled pinion .31). This meshes with a beveled gear 51. secured to the lower end of a vertical shaft .311. journaled at its upper end in the plates 4 and 5. and at its lower end in a bracket 53. carried by the pedestal A housing 5 of sheet. metal. is preferably arranged to cover and enclose the gear 51.

A stuffing box 53. similar to the stufling box it). is provided adjacent the upper end of the. shaft 52. to p event leakage therearound. such stutting box being closed by means of a plug 56. The upper end of the shaft 5'2 carries a pinion .34. which i lo and and it movable bottoms of the tub or container. which meshes with the annular gear above described.

Referring now more particularly to Figures 1. 3 and 4. it will be seen that belts 5T. 58, run over pulleys 48 and 49. respta-tively. These belts also pass around pulleys 5t) and (30. respectively, which pulleys have rigidly attached thereto clutch members (31 and ('12. respectively. These pulleys and their as sociated clutch members are loosely mounted upon a shaft (t3. journaled in bearings (34. carried by a swinging bracket (it). pivotally mounted as at (36. on the base of the machine. and having formed integral there with. an upwardly extending bracket (37. through which passes a set screw GS. adapted to bear against the side of the pedestal It is obvious that by tightening this set screw. the bracket (35 may be swung on its pivot. and the tension of the bells ST and 55 thus adjusted.

ltigidly secured to the shaft (33. is a third pulley it). around which passes a belt To. This belt also engages a pulley mounted on the shaft of a motor 71. such as an electric motor. supported on a bracket 72. pivoted at one side to a boss carried by the pedestal 25. as indicated at. Tit in Figure l. liy virtue of this pivotal mounting. the weight of the motor Tl serve to maintain the necessary tension on the belt Tl).

Splined upon the shaft hi). at a point between the clutch disks til and (5; is a sleeve 74. somewhat shorter than the distance be tween the clutch disks ()1 and (12. and carrying at its ends complemei'itary clutch members T5 and To. The sleeve 71 is capable of eudwise movement on the shaft (53,

and when in one position, as illustrated in Figure 3. the clutch member T5. at one end thereof. engages the clutch disk or member tit. and when in its oppt;-site po ition. the clutch member it engages the clut h disk or member (32. The reciprocation of the sleeve it upon the shaft 2). is brought about by means of the following me hani m. split yoke Ti loo-cl encircles tln sleetc it. and i held in a groove between annular ll' lll dcrs Th. thereon. This yolve arries a pair of oppositely projecting pins T5. which are pivotally engaged by the free ends of a Y-shapcd fork Mr the stem *1 of whi h slides freely through an elongated bos or guide H2. rigid with a yoke or crank N l. ecured to a vertical shaft Ht e l iyure .il. compression spring Hf i inttrpo cd between the fork St) and yoke s2 and s rve to hold the sleeve T4 in either one of its cie tremc |it;rltl()ll.s. to which it may be thrown, The shaft f is journaled at its lower end in a bearing Ht'i ee Figure I" carried bv the base 1. and at its upper end. p1ts-c through a stufliug box HT. up into the space below the fal e bottom '1! of the clothe container.

In order to produce ciiculation of the water from one part of the clothe container to another. I provide a pipe system oo at. extending from the bott m of the wash chamber to the bottom of the cylinder t. as clearly shown in higiirt Thi pipe ys tem includes a thrce-way \alic Etl. operated by a handle J2. and fr m thi valve extends a nipple SM. to which a piece of hose may be attached. During the normal operation of the machine. th thr i way valve is so set as to establish communication between the pipes W) and ill. and thus. as the piston Ill reciprocatcs in the cylinder (3. water is drawn into and expelled from such cylinder. thus causing circulation and agitation of the water in the clothes container.

The operation of my improved -machinc. as a whole. will now be briefly describtal.

The clothes to be washed are placed in the annular space or chamber between the tub and cylinder 11 and the container is filled loll till

nearly full of water. The motor Tl. running continuously, drives the shaft (33, and this, through the clutch members T5 and (il. as shown in Figure 3, and the belt :37. im parts rotation to the pulley 4S, and [)illit t. 44, thus turning the. gear -13. This. in turn. drives the pinion l5, and through the a nts 50 and 51, shaft 52 and gears fit and 2e, causes the plate or t'alseltottom it to revolve, thus moving the mass of clothes around in the annular wash chamber and subjecting them to the action of the rubbing elements. At the same time, the gear 43). acting through the friction clutch members 42 and 35, drives the screw shaft 312 in such a direc tion (say) as will cause the plunger carrying piston 28 to descend. As this piston dcscends, the water contained in the cylinder 12, below the. same. is forcibly ejected from the perforations 13, in the form of jet which are discharged radially into the an nular wash chamber, where they impinge upon and pass into the mass ot clothes.

After the plate or false bottom 1.! has turned a predetermined distance in one di rection, the pin 89 will strike the lever ss. thus shifting the sleeve or chitcl member 74, to its opposite position. The pulley 3a. belt 57, pulley 58 and pinion it now run idle, and power is transmitted from the shaft 63 through clutch members To and a2. pulley (it), belt 58,2111tl pulley 5%), to the shaft 92 in the opposite direction, and tllet) to the gear 43 This gear will also he driven in the opposite direction, due to the tact that the point of driving is diametrically oppte site to that previously employed. Thus, when the sleeve 74 shifts, the direction of rotation of both the shaft 52 and the screw shaft 32 is reversed, whereupon the plate it begins its rotation in tile opposite direction, and the piston 28 begins to travel upwardly, again forcing the water out through the perforations 13, in the form of jets. The ratio between the gears 43, 45, so. 5i and 54, and the pitch of the screw 32 is such that the piston 28 is caused t make a complete stroke during the time'that the plate it makes a complete oscillation. Thus, the plate and piston operate in unison. It will be observed that the clothes and water in the annular wash chamber are simultaneously subjected to agitation in three diti'erent. directions. First, there is the circune terential movement, due to the rotation of the plate 24. Fecond, there is vertical move ment, due to the surging ot the water up and down in the container, owing to the ttctiOI] ot' the piston 2b, and al o, to the action of piston 31, in the cylinder (3, operating through the pipe system Uo hl. 'lhirdly. there is the radial agitation due to the high pressure jets issuing from the oritices 13 in the cylinder 12, This combined action of circumferential, vertical and Lozzasa siniultano ously. serves to very etiectively and quickly remove all solubl matter t'roni the t'lt)tl!r-. 'lln sluice below bottom or piatc ft. to i'ccci'te :tr tltfjt ihltr oi and, grit or oth r foreign material with which the tlothe might have been ctaitaminated, as tretpiently occur in tl u e ot' bathing Mitts, etc.

It is sometimes t'ottnd thzi: in the annular wash chamht-r. c rcribed. is :-'o violent as to damag the thinn r tititl tin-er ari cleot' clothing. and in order to avoid this, such tltilt'tiit' articles may be eltertiwly washed by separating them trom the rou; h clothc-- and placing them in the cylinder 13. Then, it the piston 21 r sciprot:ll(. they are subjected to an intermittent pressing or stpieezim action. which thoroughly tort-es the water through them, and etl'ectively cleanses them without any rub billg' action. l lcg'mtl iii r provision (ti :1 separate com airtment t'or delicate articles or" clothing, and the washing oi' such articles without subjecting them to rubbing action, a an important feature of the invention.

in addition to using the cylinder 12 as a scpaiatc wushi compartm nt, 1 also contemplate employing it as a press to wring or extra t the surplus water from the mass of clothes. a'l ter they have been \\'a hed. in carrying out this phase of the operation, the machine is preferably fittlppt'tl by opening the motor circuit. w th the piston 2h at the lower end ot rokc, uch piston then constituting the tiottoin ot the cylinder l2. The cover or clo ure it is removed, and the mass of clothes is pla ed in the cylinder. The cover or closure it is then replaced and locked in position, and the llltlellllitf again started. ..\s the j if til tiaiels upwardly, it compresses the mass ot' clo hes between itself and the cover or clo ur thus ellectively forcing or squeezing the water from them. The 't unction ot' the triction clutch 3.1- .2 is to limit the pressure which may be exerted in this way by the piston "R, and thus pre vent damage to the t toiho t r to the machine. Alter a predctcrminct j.ittttt* has been exerted, the clutch member 4:1, carried by the gear 43, will sltip, relative to the clutch member 3.3, and the screw hatt will remain stationary.

In many washing machines now on the. market, great ditlicuity is experienced in removing the water from the machine, after the washing is comoletcd. it being necessary. in most case to draw the water oti' in buckets or the like. 'lhi' is due to the fact that. washing nuichine.-- as usually built, are lower than the average sink, and therefore. there is no way to drain the water out of them into such sink. In my improved ma chine, l overcome this detect by means of the cylinder 6 and piston 251, above deradial agitation, all operatirn tiaagitation at tit't' th lib J lltt llo

till

scribed. After thc washing is completed. I permit the machine to continue to run while throwing the handle 92 over to such a posh tion as to di connect pipes 90 and 9t. and connect pipe at with the nipple all. to whi h a hose leading up to the sink. or other con venient drain, has been connected. \Y th the valve in srch position. it obvious that as the piston 31 descends. it will force the water in the cylinder (3 out through the pipe SH and nipple 93 and hose conne tion. and when the piston again riseto its uppermost position. as shown in Figure 2. water will again till the cylinder t3. enter ng the same through the openings ti". at the bottom of the cylinder 12. Thus. by throwing the threeway valve into the position described. the piston 31 and cylinder t' are caused to operate as a pump to discharge the water from the machine and force it out to a higher level. Thus. the same elements which constitute circulating and agitating means during the washing operation. may be caused to constitute a pump to force the water out of the machine after the waste ing operation is completed.
