WASHING-MACHINE.-

To all whom t may concern.' Y

Be it known that I, MICHAEL BOGRE, a citizen of thepresent domain of Hungary, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Washing-Machines, of which the followingis a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in washing machines, pertaining more'particularly to machines of comparatively large capacity and designed for power operation.

The objects of the present invention are to provide a construction which will accommodate a comparatively large amount of clothing or other materials to be washed, and permit the material being washed concurrently,and at the same time provide the washing operation in such manner asl to produce effective Ycleansing of the material eing washed. A further object is to provide a construction in which the materials to be washed can be readily introduced into position and removed after the washing has been completed while maintaining the rubbing elements in their approximate position.

A further object is to provide a construction which is simple and eficient in operation, durable in construction and which can be manufactured and installed ata relatively low cost.

l/Vith these and other ends therefore,the nature of which will be readily understood as the invention is hereinafter disclosed, said invention consists in the improved construc-v tion and combination of parts, hereinafter more fully described, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.v

Fig. 3 is a transverse sectional view of the same.

The present invention is in the form of acontainer capable of being divided into a number of independent compartments by `Specification of Letters Patent. Patented API'. 5, 1921.

' Application filed March 13, 1920. Serial No. 365,549.

' the use of rubbing surfaces, each compartment being practically independent of each other so far as the possibility yof distribution of material from one compartment to another is concerned, and at the'same time, the materials of each compartment are given a rubbing actionsuch as to produce effective cleansing. The container is mounted in the casing which contains the washing `fluid, in such manner as to permit the materials being washed to be introduced orremoved while the rubbing surfaces are in position, this result being obtained by providing the material container with an open side, the removal of which exposes all of the compartments at the same time, so that each compartment can be filled or emptied individually without 'disturbing thev parts which themselves produce the washing action. At the same time, the rubbing action is provided by rubbing surfaces which are movable relative to each other at opposite sides of the compartments, the result being that the material betweenfany two rubbing surfaces is being continually rubbed and turned about through the 'movements of the rubbing surfaces. Since the material container-.is located within Vthe washing iuid, it will be readily understoodlthat this turningvfand movement of material by the movements of the rubbing surfaces will act to providefor properV distribution of the fluid through the materials in a compartment and at the same timeso manipulate the materials asto insure bringing practically the entire portion of the batch into properposition for rubbing action. 1 t In the drawings, vwhich illustrate one embodiment of the rpresent invention, the fluid receiving casing is indicated at l0, thisbeing shown as rectangular in contour and of suitable depth, and which may be mounted 4on feet lOfor otherwise supported. The

course, that other forms of covers may be Mounted within the casing 10 is a conl tainer 11 comprising end walls 11, the lower ends of which may rest upon the bottom of the container, and which may be continuous from side to side of the container or may be in the form of feet, as may be desired, the perforated bottom 11b located above and spaced from the bottom of the casing, a side 11c and a side 11d, these parts with the eX- ception of side 11d, being preferably secured together, in a manner to provide for a container formation, side '111 beingremovably secured in position by suitable means, such as latches 1Q. The sides 11c and 11 are preferably perforated.

The ends 11a preferably carry rubbing surfaces 13, which extend substantially throughout the vertical length of the container 11. And, if desired, such ends 11v may project above the top plane of the casing to form supports for a crank shaft 14 presently described in detail. It will Vbe understood, however, thaty the supports for such crank shaft may be independent of such ends if such construction be desired, the particular arrangement shown providing for low cost of production.

-ln the embodiment shown, the container is designed to be divided into four compartments, this result being obtained by the use of three independent rubbing surface carriers 15, 1,5a and 15b, these carriers having some of the general characteristics of the well known wash board', in that they are preferably arranged with rubbing surfaces operative on opposite sides of the carriers. These carriers extend transversely of the direction of length of the container at spaced apart distances, three of these being shown, and'since the carriers extend practically the full width of the container, the latter is divided into four compartments, theouter compartment having as one wall an end 11 and the other wall one of the carriers, while the two interior compartments have the opposite walls formed by carriers. The carriers have a vertical length greater than the -depth of the container, so that the upper end of the carrier is located above the top of the casing,` while the lower end which passes through a slot in the bottom 11e remains below the bottom of the container.

The carriers are adapted to be reciprocated vertically, the sides of the container having suitable guides within which the carriers travel, the upper ends of the carriers being connected to the crank portions of crank shaft 14;, the latter shaft being preferably arranged on what is generally4 known as the three-point form, this beingl preferred where the number of rubbing surwhile all of the carriers are being moved by the rotation of the crank arm 14, the rubbing surfaces carried by the carriers have movements relative to each other, carriers`15 and 15b being movable relative to the stationary surfaces 13 an-d movable relative to the surfaces ofthe carrierfla.

'70 an adjacent carrier, the result being thatV From the above, it will be clear that with a batch of material in each of the compartments rotation ofthe crankshaft will cause y the three carriers to each provide for its independent cyclar movement with all of the carriers operating concurrently, and since the movements are in planes parallel to each other and to the end rubbing surfaces, there will'beproper rubbing action provided in eachcompartment so as to effectively clean the materials within the compartment itself;

Crank shaft 14 may be rotated in any desired manner, the drawings showing the use tion 10d by a suitable chain connection or other form of drive. Sincey the materials to be washed are all located on theopposite side of the en-d ofthe container from thatv ofthe motor, it will be vreadily understoodthat vifdesired, this particular cover section may be permanently secured to the casing, -although it may be found desirable to provide for a removable connectionV such as would permit it to be removed at the time that it may be desired to remove the crank shaft and the rubbing surface carriers. This may be done at infrequentintervals, and'hence the arrangement may provide for such more or less permanency of position of `this cover section.

of a small motor 16 mounted on cover sec- Y As will be understood, the use of the `four Y compartments each of which carriesv a batch of material to be washed, provides for comparatively large capacity of machine soV as to permit of a rather large oluantity'of,v

material to be cleansed at each washing opper'ation. This ability to provide for capacity'through the particular form of the rubbing surface carriers has, of course, the

disadvantage Vof requiring 'a comparatively large container, bringing inthe question ofi1 ability to readily insert and remove the ma-g terial. This is met in the present embodi-` ment by locating the container out ofthe geometrical center of the casing, andl locating it closer to one side than to the-other, locating theY removable side 11d on that Vside of the container which is farthest removed from the side of the casing, which not only permits of ready removal of theside 11c1 but or removedY `from either` of the compart' ments, the removal being toward the side of the casing at which the operator is standing and away from any possibility of the clothes being brought into contact with either the crank shaft 14 or the connectionv between the-crank shaft and theindividual carriers.`

This position of the container locates the crank shaft to one side of the longitudinal center of the casing, as shown in Fig. l, since it is desirable that the connections between the crank shaft and the carriers be located approximately the center of the latter in order that the carriers may'reciprocate without undue difliculty. It is because of this location that-the cover sections are divided in the manner shown, the line of division beingsuch as to permit each ofthe cover sections/to be opened outward without diiiiculty. During washing operations both covers are closed, and it may be necessary only to open cover lOlin-rV inserting or removing the materials to be washed.

It will be understood, of course, that the container may be located at the geometrical center of the casing, in which case the spaces at the sides would be equal; since, however, the materials are to be inserted or removed only from one side, it is not necessary to provide the same amount of space at the opposite side of the container,and for this reason I prefer to employ the general arrangement shown in the drawings.

The particular form which may be utilized in producing the rubbing surfaces, may be varied to meet individual preferences, any of the well known forms being capable of being employed, the invention pertaining rather to the manner in which the surfaces are moved relative to each other both in direction and the means employed, than to the particular form of the rubbing surfaces.

As will be understood, the crank shaft if proper bearings are used, can be readily removed by an upward movement carrying the carriers from the container, it being understood that the connection with the motor will be made inactive, or the motor itself removed with the arrangement. This will permit removal of the container itself bodily, shouldv such action be found necessary. Since, however, the materials to be washed are wholly contained with the container itself, removal of the latter is not necessary, since the contents of the casing itself by a suitable drain cock.`

As'will be readilyunderstood, the general construction is such as to provide for large capacity operations and is of such'achar-L acter'as to be simple' and efficient inoperation, durable in construction and capable ofl being manufactured at* a comparativelyV smallcost. Y, l Y

If desired a member 1-8 may.- be located below and'preferably in alinement-with removable side lld, this .member being'lpref-- erably perforated. Thisvelement acts as a barrier against materials passing'y beneathl the container should any of such materials be dropped into the fluid content during `removal'of abatch. Y gf As will be understood, the'usejof individual compartments not only enableseach batch to be of a size-readily manipulable in the Washing operation, but also enables the. batches to .beindividual in characteristics.V

For instance, the quantity mayv vary in the a preferred embodiment of the invention, it

will be readily understood that changes Aand modifications therein may be found desirable or essential in meeting the various exigencies of use, and I desire to be understood'as reserving the right to make any and all such changes or modifications therein as may be found desirable or necessary, in so far as the same may fall within the spirit` and scope of the invention as expressed inthe accompanying claims when broadly construed.
