Application filed March 31, 1920. Serial No. 370,072.

To all wit-0m it may concern:

Be itlmown that l, EDWARD H. DOLDER, a citizen of the United States, residing at Serena, in the county of La, Salle and State of Illinois, have invented a certain new and useful Improvement in Washing-Machines, oi'which the following is a full,'clear, concise, and exact description, reference being bad to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in washing machines.

One object of the invention is to provide a machine for' economically and eiliciently washing clothes and other textile fabrics and more particularly that type of washing machine wherein a pivotally mounted tub or vessel is employed adapted to be oscillated about its pivotal supports.

A more specific object of the invention is to provide a washing machine of the oscillating tub type wherein the articles being washed are subjected alternately to the force or" the washing solution therethrough in one direction and the drawing or draining ofi,

in the opposite direction, of the washing solution, to thereby accelerate the removal of j the dirt or other foreign matter.

In the drawing forming a part of this spec fication, F gure 1 1s a slde elevation of a washing machine embodying my 1mof Fig. 3 coinciding with the pivotal axis of the tub or vessel. v it In said drawing, '10 indicates a standard or mounting which may be of any suitableor desired form and 11 indicates the oscillating tub or vessel. The vessel 11 is pivotally mounted on the standard 10 by any suitable 'means such as the studs 12 which are preferably formed integral with spiderlike brackets 13 secured to the opposite'ends 14-14 of the vessel, In the instance shown,

I the machine is adapted to be manually operated and for this purpose I provide a handle 15 which maybe seated at its lower end ina suitable socketl6 formed integral with one of the brackets 13. As will be understood by thoseskilled in the art, the

machine is, of course, adapted to be mechanically operated by suitable mechanism.

In carrying out my invention, I preferably make the vessel 11 of suitable ova-l cross-section, as clearly indicated in Fig. 2, thereby providing curved.- bottom and side walls as indicated at 17. The vessel may be made or any suitable material and pretflange 19 indicated most clearly inFig. 2,

forming suitable guides for the extended ends or" a pin 20 carried by the cover which is preferably formed in two sections 21 and 22, pivotally jointed as indicated at 23, the section 22 being pivotally attached to the vessel llas indicated at 2%. p Y

On the interior of the vessehl provide what may be termed two partitions indicated bythe references Ar-A. Thesaid partitions AA are symmetrically disposed with respect to the axis of oscillation and the same are extended from end to end of the vessel in lines parallel to the said axis. The partitions A extend from points 25 at the sides or" the vessel which are at a level approximately one-half way between the axis and the lowermost point of the vessel. The partitions are sloped slightly upwardly from the points 25 to the point indicated at 26 when a relatively abrupt curve is made in each partition as indicated at 27 and thereafter the partitions extend vertically as indicated at 28. As clearly indicated in Fig. 2 the portions 28 of the partitions are separated an appreciable distance and their top edgesterminate above the axis of oscillation. In actual practice, the partitions A will preferably be made of sheet metal and provided with a plurality of perforations or openings as indicated at 29, it being observed that said openings 29 are provided in all parts of the partitions including the vertical sections 28 thereof, for a purpose hereinafter described. A removable cover 30 is provided to close the opening formed by the upperedges of the vertically extend ing sections 28 of the partitions. By removing the cover 30, it is evident that the "operator may obtain access to the lower part of the tub for cleaning the latter out when desired. The water or other washing solu-.

' upper compartment being appreciably larger than the lower compartment. Furthermore, by extending the partitions vertically near the center of the vessel, as heretofore described, the upper compartment is divided into what may be termed two chambers, the

upwardlyextended parts of the partitions forming, in effect, a hollow barrier or baffle which serves to keep the articles being Washed divided into two separate batches.

In operating my improved machine, the clothes are introduced into the vessel onthe upper sides of the partitions and divided into two substantially equal batches, one on either side of the said barrier. Water with soap Or other ingredients desired to facilitate the cleansing operation, is introduced so as to reach a level corresponding approximately with the points 26. The vessel is oscillated first to one side and then to the other. During this action, it is evident that one batch'of the articles being washed will descend and the washing solution will rush through the perforations in the corresponding adjacent partition A and force itself through the articles. At the same time, the other batch of the articles is being elevated; and the washing solution will :drain off therefrom through the other partition A.-

In the case of the batch of articles which is elevated, it is evident that the same will tend ,to fall on to the curved section 27 and section 28 of thecorrespondingpartition and hence the washing solution will drain through these portions of the partition andwill be permitted to fall back into the main body'of the washing solution, thus facilitating the deposition of the dirt or other I foreign matter in the bottom of the tub by sedimentation.

In actual practice, I have found that better results are obtained by permitting the vessel to remain stationary for a very short interval at the end. of each oscillation, as

this gives the washing solution ample time to drain through and from the uppermost batch of the articles. This latter action, as I have found from actual observation, appears 7 to produce, in effect, a degree of suction or vacuum which greatly accelerates the cleans ing of the clothes or other fabric articles and. apparently draws the dirt from the clothes or other articles, as contra-distin guished from a rubbing action.

I have described the partitions A as being perforated but this term is to be understood in a broad sense and not in the usual restricted sense since it is evident that the same results can be obtained by using partitions which may be made of other materials, so long as the said partitions are of such character as to properly sustain the clothes or other articles and prevent them from falling through and at the same time permit the passage of the washing solution readily therethrough from one side to the other. Various other changes and modifications will readily suggest themselves to those skilled in the art and all changesand modi- .fications are contemplated that come within the scope of the claims appended hereto.

I claim: g 1. In a washing machine having a suitable standard, the combination with a vessel having a smooth interior surface, said vessel being. pivotallysupported on said standard and adapted to contain the articles to be washed and the washing solution; of partitions within said vessel extending substantially parallel to the-pivotal axis thereof,

said partitionsbeing provided with openings therein adaptinga washing solution to pass therethrough, said partitions being arranged to divide the interior of the vessel into an upper compartment and arelatively smaller lower compartment, said partitions being also upwardly extended in spaced relation on opposite sides of'the pivotal axis near the center of the vessel to form a bar- .rier and thereby divide theupper compartrnent into two portions, whereby the articles in each chamber are alternately subjected to immersion in and withdrawal from the washing solution as the vessel is oscillated.

. 2. In a washingmachine having a suitable standard, the combination with a vessel having a smooth interior surface, said vessel being of substantially ovalcross section and pivotally mounted on said standard and adapted to contain both; the articles to be washed andthe washing solution; of partitions extending parallel to the pivotal axis of the: vessel within the latter, said parti-' tions. havingjopeningstherein to permit passage'of the washing solution therethrough,

the partitions dividing the vesselinto upper and lower compartments and having portions thereof extending upwardlyin spaced relation onopposite sides of the pivotal axis near the center'of the vessel to thereby form barrier in the upper compartment and dividethe latter. into two'portions, said barrier extending above the said pivotal axis of the vessel. c

3; In a washingmachine havinga suitable standard,:the combination with a vessel having an interior surface free from projections, said vessel being pivotally supported.

on said standard and adapted to contain the articles to be washed and the washing solution; of partitions having openings therein disposed within said. vessel and extending subs antially parallel to the pivotal axis thereof, said partitions extending from points at the sides of the vessel disposed below said pivotal axis toward the median plane of the vessel and then upwardly to points above the said pivotal axis, said upwardly extended parts of the partitions being spaced whereby the upper part of the interior of the vessel is divided into two portions by a hollow barrier.

4. In a washing machine having a suitable standard, the combination with a vessel, said vessel being pivotally supported on said standard and adapted to contain the articles to be washed with the washing solution; of partitions having openings therein disposed within said vessel and extending substantially parallel to the pivotal axis thereof, said partitions extending from points at the sides of the vessel disposed below said pivotal axis toward the median plane of the vessel and then upwardly to points above the said pivotal axis, said upwardly extended parts of the partitions being spaced whereby the upper part of the interior of the vessel is divided into two portions by a hollow barrier; and a displaoeable cover at the tops of said upwardly extended portions of the partitions arranged to permit access to the interior of the vessel below said partitions.

5. In a washing machine having a suitable standard, the combination with a vessel, said vessel being pivotally supported on said standard and provided with an opening in the top thereof; of two partitions within said vessel arranged parallel to the pivotal axis thereof, each of said partitions extending substantially vertically downward from a point above the pivotal axis to a point therebelow and thence outwardly and downwardly to the side of the vessel, said partitions having openings therein to permit passage of the washing solution therethrough; and a closure for the opening formed between the uppermost edges of said partitions.

In witness that I claim the foregoing I have hereunto subscribed my name this 17th day of March, 1920.
