Definitions

  • My invention relates to washing machines and is more particularly concerned with a novel washer having an improved washing action and which, in one preferred embodiment, comprises an inexpensive, compact, portable unit adapted to be set in and to wash clothes or other articles efficiently in existing wash-basins or tubs of whatever size or shape.
  • washing machines now being marketed for home use are, so far as I am aware, all complete self-contained units, including a tub for holding the water and clothes.
  • the fully automatic models include water inlet and drain connections and pumps and automatic devices for controlling the washing operations with a minimum of attention from the operator. But such machines are costly and beyond the means of many people.
  • both manually controlled and fully automatic washers are bulky and none of them could properly be called portable for convenient transportation and storage.
  • Ano-ther fault with many washing machines now on the market is the fact that they do not wash the clothes eiciently. Furthermore, in many of them the action is of such a nature or so vigorous as to be likely to damage the articles being washed, so that garments of delicate materials must be washed separately by hand.
  • an object of the present invention is to provide a novel washing unit whose washing action more nearly approximates that performed by hand than any present washing machine.
  • Another object of the invention is to provide a clothes washer which, because it will operate irrespective of the size or shape of tub in which it is disposed, is adaptable for use either in a machine having its own tub or as a portable unit to be set by the user in any available washbasin, sink, bathtub, or convenient container.
  • Still another object of the invention is to provide a clothes washing unit of the type described which in its portable form is inexpensive, conveniently small in size, light in weight, and shaped for easy storage or for carrying with the traveler for use in overnight accommodations.
  • Yet another object of the invention is to provide a novel clothes washing unit in which the washing action is gentle yet thorough and in which the moving parts cannot become entangled in and tear the garments being washed.
  • Still a further object of the invention is to provide a new and improved clothes washer which will wash efflciently with a high ratio of clothes to water, thereby permitting the handling of a considerable number of articles even in a small basin and conserving hot water.
  • a still further object of the invention isv to provide a novel washer of the type described which has a selective action in operating on individual areas of each garment separately and which effectively prevents tangling of the articles with each other.
  • the invention is featured by the provision of a simple and inexpensive washer assembly which, in portable form, is adapted to be carried about and set in any convenient container and plugged into any convenient electrical outlet or, in a permanent installation, to be mounted in a suitable tub, for .exe ample, in a semi or fully automatic machine.
  • the novel washer unit comprises a hollow perforated clothes engaging member adapted to be at least partial-ly submerged in the liquid in the container, a drive for reciprocating this member generally vertically and a pump for withdrawing liquid from the interior of such member and forcing it outwardly over one end of such member into the container.
  • the clothes engaging member surrounds a drive shaft driven by an electric motor and is reciprocated by a spiral cam arrangement on the shaft.
  • the shaft also drives the pump which may be an impeller keyed to its lower end near the bottom of the container or a force pump moving with the washer member.
  • the outer Vsurface of the perforated member on each down stroke rubs any garments in contact therewith, exes the same and tends to push them downwardly toward and eventually into the outwardly moving stream in the bottom of the container to be whirled thereby away from the washing member.
  • the action of the impeller or pump is such as to exhaust the liquid from within the hollow perforated member, causing surrounding liquid to cascade through the perforations, thereby drawing the clothes toward the perforated member.
  • Fig. 1 is a front elevation with parts broken away and partly in section illustrating a portable embodiment of my novel clothes washer set in a tub;
  • Fig. 2 is a bottom view with portions broken away of the same, omitting the tub;
  • Fig. 3 is a fragmentary vertical cross section of a modified form of washer in which a reciprocating pump is substituted for a rotating impeller for moving the water outwardly at the bottom and a wire basket comprises the perforated washer member;
  • Fig. 4 is a fragmentary vertical sectional view of still another form of the invention in which an annular rubber ring is substituted for suction cups for mounting the device in the basin and a further modified form of perforated clothes engaging member is employed;
  • Fig. 5 is a front elevation partly in section of a further modified form of the invention in which the clothes en gaging member is mounted in such a way as not only to reciprocate but also to oscillate rotationally during reciprocation;
  • Fig. 6 is a sectional view taken on a line 6 6 of Fig. 5.
  • my novel clothes washer in portable form is indicated generally by the numeral 1t) and is shown set in a washbasin or bathtub 12 which may be of any size or shape.
  • the washer itself comprises a waterproof electric motor 14 on which is mounted a handle 16 for convenience in carrying. Attached to the shaft of the motor is a downwardly depending drive shaft i6 to the bottom of which is keyed an impeller 18 for circulating the water in the tub.
  • the motor 14 is mounted on vertical rods 2b, the bottom ends of which are held by nuts 22 to a hollow cylindrical supporting member 24 formed of sheet metal or any other suitable material.
  • there are mounted on the bottom of the member 24 three suction cups 26 by means of mounting screws 28 for holding the machine fast to the bottom of a basin or tub to prevent accidental upsetting.
  • the vertical shaft 16 is provided with a reverse slotted spiral cam 30 in which rides a cam follower 32 to which is attached a spider 34 having arms to the outer ends of which is affixed the generally cylindrical hollow perforated clothes engaging member 36.
  • the member 36 is perforated with numerous openings 33 for the admission of wash or rinse water as hereinafter described.
  • the base of the supporting member 24 is provided with a circular opening 40 at its center through which protrudes the lower end of the shaft 16 and beneath which operates the impeller 1S for drawing liquid from within the members 24 and 36 and forcing it outwardly along the bottom of the container 12 in radial fashion.
  • the washer member 36 is provided with a series of annular ribs 42 between which are located the openings 38 and the -lower surfaces of these ribs constitute surfaces for pushing the clothes downwardly with each stroke of the washer.
  • the device may be set in any suitable available container such as the wash-basin in a bathroom, the bathtub, or a washtub, or, indeed, even an ordinary pail.
  • the clothes washer rests on the suction cups 26 which attach them- 4 .Y elves to the bottom surface of the tub and prevent accidental dislodging.
  • the clothes washer is mounted in the center of the container, leaving an equal space between the basket 36 and the container walls.
  • the clothes are placed in the container, preferably being spread evenly around the outer periphery of the basket, but if not so spread they will quickly arrange themselves uniformly once the machine is operating, and water and a quantity of detergent added.
  • the impeller 18 When the motor 14 is operating, the impeller 18 will revolve and force a strong radially directed current of water outwardly between the suction cups 26 and along the botto-m of the container, as shown by the arrows. At the same time, the ca m follower 32 will ride up and down in the spiral cam 30, thus causing-vertical reciprocation of the basket' 36. The impeller 18 quickly empties practically all the wash water within the members 36 and 24, whereupon the external liquid immediately begins cascading through the openings 38 to replace the water which has been pumped out.
  • Some of the garments may block some of the openings 38, but if the tub is not overloaded and the liquid level adjusted to achieve maximum suction, there will always be some free openings and in consequence in the areas above the bottom of the member 24 the wash water will pour radially inwardly through the member 36 from all sides. Clothes floating in the water are thus rapidly carried by the -converging stream toward the reciprocating washer member and individually are rubbed by the movement of this member while portions thereof will be pushed, exed and rolled downwardly at each stroke toward 4the current of water being emitted by the impeller.
  • a slightly modified form of the invention is shown.
  • ln place of the ribbed perfor-ated cylindrical washing member shown in Fig. l, l have sub# stituted a simil-arly shaped wire mesh basket 36a whose ⁇ discontinuous side wall performs the same function as the ribs 42 in engaging and pushing the adjacent clothes downwardly, while permitting cascading Vof thewater v therethrough.
  • a vertically Vreciprocating force pump 44 comprising a disc-like piece of flexible material such as rubber, moving with'the basket member ⁇ to force the water downwardly through a series -of openings 46 in the bottom of the supporting member 24a.
  • Fig. 3 functions in virtually the same manner as that of Figsv 1 and 2 except that the output liquid stream of the force pump is intermittent instead of continuous. But in this case, as in the previous, the washing action will proceed independently of size or shape of container, and -the eiciency of washing is comparable to the best commercial automatic washers.
  • Fig. 4 I have shown ⁇ still a further modification in which the perforated washer member 3617 ⁇ is provided with a series of receding downwardly facing annular steps 50 of decreasing radius ytoward the bott-om. Likewise, I have shown a deiiecting skirt or apron 52 extending in such a way as to coniine the stream of ⁇ liquid forced outwardly by the impeller 18 to -a narrow area.
  • the support 24b is provided with 'a perforated bottom plate 54 resting upon a ring 56 of rubber or the like which in turn supports the machine in the bottom of the basin.
  • the suction for holding the machine upright is provided by the action of the iim-peller which tends to draw liquid not only from within the member 24b but also through the openings 58 in the plate 54 from the zone beneath -the machine and within the sealing ring 56.
  • the suction thus caused holds the washing unit firmly and p-revents accidental overturning.
  • the shape of the washer member 36b in Fig. 4 affords in some cases an improved downward rubbing Iand pushing action against the articles being washed.
  • Each over- 'hanging portion or step 50 engages the adjacent clothes and tucks them downwardly toward the stream of water emitted by the impeller beneath the apron 52.
  • FIGs. 5 and 6 still a further modilication of the invention is illustrated wherein the supporting rods 29a, corresponding to the rods 20 in Fig. l, have been twisted and the arms of the spider 34a are provided with openings 35 to accommodate the rods and be guided thereby for rotationally oscillating the clothes engaging member 36C as it reciprocates vertically.
  • This twisting alternately in opposite directions of the washer member I have found may in some cases improve the washing action While at the same time it tends to cause the clothes to rotate slowly about the washer.
  • the ⁇ embodiment of Figs. 5 and 6 operates in substantially the same way as the previously described embodiments.
  • a feature of considerable importance is the selective action of the washer member 36 in operating uponeach garment or successive areas of larger articles individually.
  • my vertically reciprocating washer member 36 of Fig. l (and 36a, 36b, and-36C of the remaining iigures) is in no sense an agitator as that term is used with reference to conventional washing machines.
  • the motion of this washer member has no substantial effect upon the circulation of the water and is not designed to agitate in the conventional manner a body of clothes and water. Instead, its function is to scrub, bend, and furnish a surface against which each garment is squeezed by the weight of the water seeking to cascade through the openings 38 While on each downward stroke its surface engages portions of the articles being washed, pushing or tucking them downwardly toward the outwardly directed stream induced by the pump at the bottom of the unit.
  • the clothes washer is particularly useful to persons living in crowded quarters or operating on a limited budget where it is desired to save the cost of sending clothes to a commercial laundry and yet where a large automatic washer is beyond the reach of the pocketbook or exceeds the floor space of the establishment. Likewise, the clothes washer will be found very convenient for the traveler who stops in hotels or overnight cabins and would like to do his own washing, the machine being light and compact for easy packing and transporting.
  • the washing operation may be made almost completely automatic by starting off with a good quantity of soapsuds but leaving the hot vwater turned on slightly so that dirty water and scum will continuously discharge through the overiiow outlet of the basin. The water thus gradually becomes clean, and washing and rinsing will have been performed in a single operation without any attention.
  • a clothes washer unit according to the invention may be mounted permanently in its own tub.
  • the successful operation of the washer in no way depends upon the size or shape of the tub in which it is permanently mounted.
  • permanent mounting makes available the novel washing action of my washer in a semi or fully automatic machine. Such an installation naturally would be more expensive and lack the numerous advantages of portability but at the same time would yield the benefits of automatic operation.
