I IThis invention relates to-washing machines.
"Heretoforelthe steps of moving 'the wash in the washing liquid and the removal of suchiliquid, were carried out by separate .devicessuc'h as washing machines, wringers, centrifuges and; presses.
'An object of the. present invention is .the provisionofa simple and-effectively operating device wherein the movement ofthe wash'i'nthewashing liquid and the'remo'val of :the latter are carried outdirectly one after 'theother'in'ithe'same device, and withoutbeingl broken up into sepa' rate steps.
Other objects of thegprese'n't invention will become apparent .in the course of the following specification.
The objects of the present invention may be realized through the provision of a washing 'machine having a rotary drumwhich contains the wash and which isprovided with one or two end I I r I hollow spaces-Handarerotatably connected with .walls movable axially for thepurpose'of compressing the wash.
The invention will appear more clearlyfrom the following detailed description when taken in connection with the accompanying drawings showing, bywvay ofexample, a-preferred embodiment of the inventive idea.
In the drawings:
Figure 1 illustrates diagrammatically,'inllon- "'gitudirial section a washing 'maichine construeted 'in 'accorda'nce with thaprindiples of thezpresent invention;
l-Figure fl-is atransverse sectionalongtrtheiline 12- 2 of Figure .1.
The washing: machine shown-diagrammatically in the drawings includes. a cylindrical container Ill whieh is mounted onth'elegs II. In "connec- "tion with th'e"'containe1" I'0,"there"are specialopenings or devices 'tol'et water-into the container, to add washing-powder to the water, to heat the washing fluid and to remove it from the container. 1
As these openings and devices are not a subject of this invention, these openings and devices are not shown in the drawings. A drum I2 is located within the casing I0. The drum I2 has end members 3 which are rotatably connected with the 45 end walls I3 of the casing I!) by means of flanged pipe ends I4 which are connected to the end members 3 and which extend through tubular supports I5 provided in the end walls I3 of the casing II).
The end members 3 of the drum I2 are of smaller diameter than the central section It of the drum. The cylindric wall of this central section I 6 is perforated.
The section I6 of the drum contains end parti- *2 tions 4" which are movable' within the drumiW-t'he direction of its longitudinal axis.
The inner surface of the central 'portion lt of 'the drum' I2 is provided with guide railstfi'the outline of which is indicated in Figure '2." The end partitions 4 have recesses =I-1 corresponding to the outline of the guides 8 so that the' end partitions4 are mounted upon the'guides a. It is apparent that the guides 8 L extend into 3 the in- 10 terior'of the drum and-areused 'fonmovingthe wash.
Tension springs 'l arelocated vi itl'iin' the hollow "spaces 20, "and 'are 'attaehed to the 1 end walls 'andpartitions l. Obviously; the-springs-"l may be' located outside of the-' bod1es 5, 3 if desired.
The springs Tare used -to pull" the partitions 4 toward the-members'--3,-'-as indicated in Figure .1. The stretchablebodies 5 are enclosed byfiguides 9, consisting of inter-engaging, telescopingizsections I9 of varyingdiameter. "The innermost'rsec- "tions I 9 are attached to th-e partitions 1 4;:wh-ile the outermost sections' a're attached to the unembers 3. The section's I-Bare slidableonei -upo'zta-the other so that they may "be located 1 int'the' sex- ";tende'd' position shownon the left =iside iofs11lgure 1,-"or in'-'-the*collapsed positionshownconv thexright side of Figure 1. a The device -is' operated as follows: 40 Water isallowed to enteri therco'ntainer. lflsan'd to fill one half of it. A water-softening and detergent composition is dissolved in this water. Then it is heated to the desired washing temperature. The wash is inserted into the interior of the drum I2 through any suitable openings not shown in the drawings, whereupon it is washed and rinsed in the usual manner by rotating the drum I2, the interior of which communicates with the washing-fluid in the container II] by the perforations in the cylindrical wall. At that time the partitions 4 are in their withdrawn position, as indicated on the right side of Figure 1. Upon completion of the washing operation, and while the drum I2 is still running, the rinsing Water is removed from the container Ill.
In accordance with the present invention wamoved into the position shown in Figure: 1,
namely, until they are moved close to the center of the drum l2. Since the drum l2 continues its rotation the wash is substantially uniformly distributed between the two end partitions 4. With increased pressure more and more water is pressed out of the wash. Upon completion of this operation the connection of the pipes 6 with the source of the pressure medium is interrupted and the hollow spaces 20 are connected by the pipes 6 and any suitable devices, not shown in the drawings, with any space or room, not under pressure. Then the springs I will move the end partitions 4 back to their initial positions, which are indicated on the righthand side of Figure 1, whereby a part of the water leaves the hollow spaces 20 through the pipes 9. The wash can then be removed from the machine in the usual manner.
The operation of the machine is enhanced by a suitable construction of the parts thereof. For example, the inner surface of the movable partitions 4 are preferably quite smooth and, if necessary, polished so that the wash, in the course of the compression, will slide along these walls and thus can be uniformly distributed between them.
If available water pressure is not sufiicient to compress the wash then the required water pressure can be produced by a pump which can be operated manually or by an electro-motor. It is apparent that the above example has been given by way of illustration, and that many changes can be made therein within the scope of the present invention. By way of example, the guide rails 8 which prevent a rotation of the longitudinally movable walls in relation to the immovable end walls 3, and which are necessary for washing machines the direction of rotation of which is periodically reversed, may be eliminated in the case of washing machines wherein the drum l2 rotates in one direction.
When the stretchable bodies are sufllciently strong mechanically, or when they fill out the entire interior of the casing, it is possible to eliminate the guide members 9.
As already stated, the springs I may be located outside the hollow bodies 5, namely, they may be placed close to the edges of the end walls between the guides.
Washing machines of smaller size can be provided with only one movable end partition 4.
- work, time and space.
The described washing machines have considerable advantages in comparison with prior art devices. These machines can be constructed in every size, for household use as well as for large installations. The possibility of washing the clothes and removing water from them in a single device constitutes a considerable saving in The various operational steps which heretofore took place between the introduction of the wash into the washing fluid and the drying thereof are reduced to a single operation which requires very little supervision, particularly when the entire operation of the machine is regulated automatically. The wash will not be damaged by the pressure since it is not subjected to any twists or turns.
An advantage of the described machine, as compared to centrifuges, is that the machine, as constructed in accordance with the present invention, is able to attain pressure which can be achieved only with centrifuges capable of a high number of revolutions, requiring very firm and powerful installation and, thus capable of use only for large works.
If soap-carrying liquid is pressed out of the wash at the end of the main washing operation, a considerably smaller amount of water is required for the rinsing. This is particularly advantageous in localities having hard water.
What is claimed is:
A washing machine comprising a stationary casing, the casing having end walls, a drum rotatably mounted in the casing, the drum having at least one partition axially movable within the drum, resilient means for maintaining the movable partition adjacent the corresponding end wall of the casing, an elastic bellows surrounding the resilient means, and a conduit disposed through the stationary end wall for introducing the fluid pressure into the bellows and intermediate the movable partition and corresponding stationary end wall.
