WASHING MACHINE.

Application filed September 21, 1922. Serial No. 589,586.

T 0 all whom it may concern:

Be it known that I, EMERY MOLNAR, a citizen of Hungary, residing at Flemington, in the county of Hunterdon and State of New Jersey, useful Improvements in Washing Machines, of which the following is a specification.

The present invention relates to useful improvements in washing machines, and has for the primary object thereof the production of a washing machine wherein the clothes received therein are adapted to be subjected to a rubbing action.

A further object of the invention s the provision of a washing machine wherein the same includes a main water receptacle hav ing a clothes receiving tray resiliently supported therein and having a plurality 'of roller elements for engagement upon the clothes for thoroughly washing the same in a simple and expeditious manner.

A still further object of this invention IS the production of a clothes Washing mach ne wherein the same is of comparatively simple construction and one wherein should any of the parts become out of order the same may be readily renewed.

With the above general objects in view and others that will appear as the nature of the invention is better understood, the same consists of the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 is a longitudinal elevational view of one side of my improved machine,

Figure 2 is a top plan view thereof,

Figure 3 is a fragmentary longitudinal cross sectional view taken upon the line Ill-III of Fig. 2 and looking in the direction of the arrows,

Figure 4: is a transverse cross sectional view upon the line IV1V of Fig. 2,

Figure taken on the line VV of the same figure,

Figure 6 is a transverse cross sectional view upon the broken line VL-VI of Fig. 2,

Figure 7 is a fragmentary longitudinal view of a portion of my device taken on line VII-VII of Fig. 2,

Figure 8 ma fragmentary longitudinal sectional view taken upon the line VII-VII of Fig. 7,

have invented certain new and 5 is a view similar to Fig. 1 and Figure 9 is a fragmentary rear elevational view of the hinged mounting for the cover of my machine, and

Figure 10 is a vertical cross sectional view upon the line XX of Fig. 9 and looking in the direction of thearrows.

Referring more in particular to the several views, there is shown a main outer receptacle of substantially rectangular configuration and comprising side walls 1 and 2, end walls 3 and a and a bottom wall 5, it being noted that the side and end walls are so disposed as to slope inwardly for purposes readily apparent. Secured in any manner desirable, to the corners of the main receptacle are supporting legs 6 having roller casters 7 positionedupon their bottom ends for facilitating movement of the machine from place to place.

Adjacent the lower ends of the side walls 1 and 2 and extending longitudinally therewith are supporting bars 8 secured in any manner desirable to the bottom wall 5 of the main receptacle. Resiliently positioned upon these supporting bars is a relatively long pan-shaped receptacle 9, having spaced, slightly inwardly of the four corners thereof annular-shaped bearing members 10 for receiving the upper ends of coil springs 11, the lower ends of these coil springs being similarly positioned within other bearing members 12 secured to the supporting bars 8.

The bottom wall of the tray 9 has depending guide rods 13 secured thereto, for slidable engagement within openings 14 in cross bars 15 supported between the side supporting bars 8. By the provision of these guide rods 13 it will be readily understood that the tray 9 is supported for a vertical reciprocating movement. In the preferred form of my invention this tray is to be constructed of wood, the bottom wall thereof having a metallic lining 16 having perforations therein for alinement with perforations within the bottom wall of the tray, the side walls thereof being also perforated as at 9.

Disposed for rolling contact upon the clothing-to be received within the tray 9 are suitably spaced roller members 17 each of which has an axial shaft 18 passing therethrough, the ends of which are adapted to be received within openings formed in spaced fingers 19. I have shown these rollers 17 as being three in number, and it is to be readily'noted'that the shaft supporting fingers 19 are integrally joined together by an upper cross bar 20 having an upwardly extending arm 22 projecting therefrom intermediate its ends. The members 22 are adapted to extend through spaced longitudinally extending slots 23 in a rectangular shaped metallic cover 24 for the receptacle. The portions of these arms 22 projecting outwardly of the cover 24 extend through suitablyspaced openings in across brace rod 24, the same being provided with vertically extending ears 25 adjacent these openings for allowing the members 22 to be bolted thereto. As more clearly shown in Fig. 6 of the drawings, this cross rod 24 has formed upon its under surface and spaced inwardly of the outer edges there of, bracket members 26, whereby pintles 27 of rollers 28 are received between these bracket members and the adjacent face of the cross rod 24. These roller members are adapted for close rolling contact with metallic inserts 29 suitably secured within cutout portions of the side walls 1 and 2 of the main receptacle. Adjacent the forward and rear edges of the longitudinal slots 23 in the cover 24 is a cross leaf spring member- 30 having their ends so formed as to flatly engage the upper face of the said cover to be bolted thereto as at 31. Centrally secured to these spring members and extending longitudinally with the cover 24 is a flat rod 32 and engaging over this red are suitably spaced depending cars 33 formed upon the cross bar 24 for supporting a roller for rolling contact with the adjacent surface of this lon tudinally extending bar 32, the cover 24 being longitudinally slotted at 3 for permitting this roller 34 to project therethrough. The outer ends of the rod 24 are pivotally secured to the adjacent flat end of connecting rods 36, the same being eccentrically pivoted to hand wheels shown more clearly in Figures 1 and 2. Each of these hand wheels is provided with operating handles 38 and positioned within suitable upstanding journals 39 secured to the side walls of the main receptacle is a cross shaft 40 upon which is rigidly keyed the hand wheels 37 whereby operation of one x'vheel will impart a similar rotary movement to the other wheel. It will therefore be seen that any rotary motion applied to the hand wheels 37 will impart a reciprocating motion to the rubbing rollers 17 in engagement upon the clothes within the tray 9 for thoroughly cleansing the same it being readily understood that the main receptacle is adapted to contain water therein having an outlet as at 41.

The end of the rod 32 adjacent the hand wheel connecting shaft 40 has secured thereto by rivets or the like 42 one end of a flat rod'section 43- which rod section formsan integral part-of an upstanding U-shaped bearing member 44 shown more clearly in Figs. 9 and 10. This bracket member 44 is adapted to straddle the shaft 40 intermediate the ends thereof and the upper end of this lJ-shaped member has an annular shaped spring bearing plate 45 formed thereon. An elongated inverted substantially U-shaped member 46 is so positioned as to have its side legs straddlethe bearing member 44, these side legs being provided vith alined openings therein for loose p ositioning upon the shaft 40, the said side legs being integrally joined slightly spaced from their lower end above the shaft 40 by front and rear cross pieces 47 for permitting the adjacent face of the annular-shaped spring bearing plate 45 to rest thereon. The hearing plate 45 has formed thereon diametrically opposed. side projecting fingers 48 which lingers project through slots 49 in the side arms of the U-shaped member 46, it being noted that a coil spring 50 has one end positioned upon the bearing platelii, the opposite end of which is also in engagement with a bearing p late 51, this plate being also of an annular shape and having side projecting fingers extending through the slots 49 in the side arms in a manner similar to the plate 45. The end wall 4 of the main receptacle is provided with a cutout portion 52 centrally thereof upon the side edges of whichis bolted or otherwise secured a U-shap ed bracket 53, the upper side'arms of which have a forwardly extending hook-shaped member 34 formed thereon for engaging over the shaft 40 in close contact With the side arms of the U- shaped member46 for effecting a central bearing member for the shaft 40.

In view of this detailed descrip't'ionrof Figs. 9 and 10 it will be readily noted that the cover 24 for the main receptacle has a swinging hinged connection to the shaft 40 for allowing the same to be swung i pwardly and rearwardly thereon forfacilita'ting "the deposit and removal of clothing to and from the tray 9. It will also be further under stood that in view of the coil s'pri'nghO at this end of the cover pressure is applied to the rubbing rollers 17 viewoftheresilient connection between the inverted 'U-sha ped bracket 46 and these rubbing rollers, it being readily understood that the pressure, of the spring is upon the spring bearing plate 45 formed on the lJ-shaped shaft straddling bracket 44 and thence to the centrally dis posed longitudinal rod 32 which red 1101: mally contacts "the periphery of the roller -34 carried by the cross bar 24 to which is operatively connected the rubbing rollers 17 The opposite end of the centrally disposed rod 32 has also secured thereto by bolts or the like a projecting arm 56 of an annularshaped flat spring bearing plate 57; this construction being more fully shown 'inFigs.

7 and 8. This spring bearing plate 57 extends between spaced vertically disposed leg members 59 of a spring housing 60, and is adapted to receive the bottom end of a coil spring 61 thereon, the opposite end of this coil spring being positioned upon a similar annular-shaped spring bearing plate 62 having side lugs 63 projecting therefrom for vertical sliding movement within slots 64 in the side legs 59 of the spring housing 60, this construction functioning as a spring pressure means to this end of the swinging cover 24 and consequently to the rubbing rollers 17 in a manner similar to the construction shown in Figs. 9 and 10 and hereinbefore described.

As a means for locking the cover 24 in a closed position the end wall 3 of the main receptacle is centrally notched as at 65 for receiving a longitudinally extending plate member 66 having upwardly projecting side flanges 67 functioning as a bearing for a sliding locking plate 68, this locking plate having formed thereon a pair of spaced for wardly extending fingers 69 for engagement over the bottom wall 60 of the spring housing 60 when the cover is in a position as shown in Fig. 7. The plate 68 has a depending screw 70 secured thereto for engagement through a slot 71 within the plate 66 for limiting the sliding movement of the locking member 68 thereon, this member 68 being further provided with a hand operating knob 72.

The forward end of the cover 24: terminates slightly inwardly of the'end wall 3 of the main receptacle and disposed between this edge of the cover 2e and the end wall of the receptacle is a clothes wringer' denoted in general by the numeral 7 3, which wringer comprises an upper and lower wringer roll 7 4: and 75 respectively supported upon the inner face of the end wall 3 by brackets 76. These bracket members 76 have vertically extending roller shaft bearing lates 77 formed thereon, it being noted that each of the rollers are formed of rubber or similar material and have centrally disposed therein the axial shaft rods 78, the opposite ends of which in the lower rollers 75 extend through alined openings in the opposite bearing plates 77, the opposite ends of the shaft 78 in the upper roller 74 being disposed for vertical sliding movement within slots 79 of these plates 77. The outer ends of the shaft 78 in the rollers provided with the usual intermeshed spur gears 80 and the shaft 78 in the upper roller 7 has vertically extending rods 81 secured thereto, each rod having a spring bearing plate 82 thereon for receiving one end of a coil spring 83, the upper ends of these coil springs contacting with outwardly bent flange portions 84: on the plates 77 these flange portions being. centrally apertured for allowing the upper end. of the rods 81 to project therethrough, it being readily understood that this construction allows for tensioning means between the two rollers. The upper roller is shown as beingprovided with a shaft extension 78 extending through an opening in the side wall 2 of the main receptacle for receiving a hand operating crank 84. In substantial alinement with the wringing rollers 74k and 7 5 the rear wall 3 of the main receptacle is provided with a cutout portion 85 of a length substantially equivalent to the length of these wringing rollers and adjacent the bottom edge of this cutout there is secured an inclined chute 86 for guiding the clothes into a clothes basket supported upon a stand hereinafter more fully described.

This basket supporting stand merely includes side bars 87, only one of which is shown in Fig. 1, pivoted as at 89 to the.

adjacent supporting legs 6 of the main receptacle. Adjacent the forward end of these side bars 87 are supporting legs 89 loosely pivoted thereto for supporting these side members in a horizontal position for receiving the clothes basket thereon. The main receptacle is provided with a swinging hook 90 adapted to engage over the forward end of the stand when the same is swung upwardly to an inoperative position.

Still another basket supporting stand is shown as being slidably positioned upon the supporting legs 6 of the main receptacle directly beneath the bottom wall 5 thereof. This supporting stand merely includes a rectangular-shaped board member 91 adapted for sliding movement upon side supporting bars 92 which bars are secured at their ends within brackets 93 having spaced vertically projecting finger members 94 between which are received these supporting bars 92. The outer end of this rectangularshaped board 91 may be provided with a detachable brace member 95 as shown in Fig. 4: and the opposite end of the board has secured thereto depending plate members 96 for contact with the brackets 93 for limiting the sliding movement of the board 91 upon the supporting bars 92.

As a means for supporting the cover 24 in a raised position the rear wall 4 of the main receptacle, has bolted, or otherwise secured thereto, upwardly extending, rearwardly inclined spaced brackets 24, notched at their upper ends at 24:. These brackets are positioned. for engagement, at their notched ends with the cross bar 24 of the rubbing rollers, when the cover 24: is in its raised position.

As the construction and manner of assembling the parts has been fully discussed above, it is believed that 'the construction and operation as well as the manner of use and advantages will be'readily understood and appreciated by those skilled in the art.

Minor changes may be made Without departing from the spirit and scope of the invcntion as herein claimed.

What is claimed is 1. A washing machine comprising a main water receptacle, a clothes tray supported Within said receptacle, rubbing rollers positioned for reciprocating movement Within said tray hangers for the opposite ends of the rubbing rollers each having a vertically extending arm formed thereon, a connecting bar between the tWo arms having guide rollers positioned adjacent the outer ends thereof for rolling contact with the side Walls of the main receptacle, and means secured to the opposite ends of the connecting bar for reciprocating said rubbing rollers.
