fabrics.

A. principal object of the invention is to producea machine of this class in which a washing member is employed havlng, a special construction which will bring about a repeated passa e of the washing water through the fibers of the fabric.

A special object of the invention is to accomplish this effect without necessitating the employment of a resilient material for the washing faces or rubbing faces of the washing members.

One of the objects of the present invention is to produce a washing machine of this type having a roller or washing member which is very light and inexpensive and having pockets formed in such. a way as to give a good washing effect.

' Other objects of the invention will appear more fully'from a clear understanding of the invention.

The invention consists in the general com bination of parts and in the features hereinafter described, all of which contribute to produce an efficient washing machine.

The preferred embodiment of my invention will be particularly described in the following specification, while the broad scope of my invention will be pointed out in the appended claims, e

In the drawings, Figure 1 is an end elevation of a, washing machine embodying my invention; Fig. 2 is avertical section taken through the machine and showing the cooperating surfaces which produce the washing effect; and Fig. 3 is a fragmentary View showing a small portion of one of the shells of the roller.

Referring more particularly to the parts, I shall now describe a small hand-operated machine embodying the invention, although it must be understood that the invention is equally well, applicable to power-driven washing machines.

In the drawings, 1 represents an upper roller which cooperates with a lower roller 2, to wash articles passed between the rollers said rollers being mounted in a suitable frame 3. The lower roller 2 may have a fixed shaft 4 carrying a crank 5 by means of which the'rollcr may be rotated. The upper roller lis preferably providedwith a shaft, 6, the ends of which are mounted in boxes 7 which may move up and down in guides 8 formed in the frame 3; and this upper roller is normally pressed downwardly resiliently by means of springs such as the spring 9, whichexert their pressure upon the boxes 7. The rollers 1 and 2 have circular heads 10 which are attached in the ends of cylindrical shells 11. These shells I]. may be formed of any suitable sheet metal, such as zinc or other pliable metal.- The shells 11 are preferably formed originally. as fiat sheets and are then secured to the heads 10 with the ends of the sheets coming together to form a butt joint 12. By means of'dies while ea'chshell is in the form of a sheet, I produce a plurality of pockets or cups 13 which are formed by pressingor offsetting the material inwardly sons to form cups with bottoms 14 "and slightly converging side walls 15. These cups or pockets are preferably formed in longitudinal and circumferential rows, and

the material between the rows is preferably ofiset so as toform corrugations 16 extending longitudinally ,of the rollers, and other corrugations 17 extending circumferentially around the rollers in such a manner as that indicated in Fig. 3. In the bottoms 14 ofthe cups or pockets of the upper roller I prefer to form perforations 18, and similar perforations 19 may be formed in the corrugations 16 of the upper roller. The lower roller is preferably entirely without such perforations.

In using the machine the frame 3 may be supported on the upper edge 20 of a tub or on a shelf, and the textile fabric or cloth 21 which is to be washed asses up from the tub where it becomes see red with water and passes between the rollers in the direction indicated by the arrows in Fig. 1. The lower roller 2 is rotated meanwhile by means of the crank 5 and the pressure of the cloth on the upper roller rotates the upper roller in the opposite direction, that is, so that the adjacent surfaces of the rollers move. in the some directionr The dicated most clearly in Fig. 2. As the cloth,

passes l'ietween the rollers, it forcesthe upper roller upwardly compressing the springs 9 so that the rollers press the material withtconsiderable force.- As the material passes toward the line which joins the axes of the roller, it becomes corninto the cups or pockets andthe quantlty of Water in the material WhiCh:!S compressed in the pockets of the upper roller becomes expressed and passes up throu h the perforations 18 into the interior of t e upper roller. A similar action takes place at the perforations 19, due to the pressure exerted on the material. For this reason the perforations of the upper roller which are approaching the center line will pass water upwardly as indicated-by the arrows. As the cloth passes out of the space between the rollers, t e compression exerted on the cloth becomes less and less, and as the cloth withdraws itself from the unperforated cups 1? of the lower roller, a partial vacuum is-formcd within these cups. This tends to draw the water from the fibers of the materialinto the cups of the lower roller and also tends to draw water inwardly through the adjacent perforations ofthe upper roller, as indicated by the arrows in Fig. 2. In this we the water is made to circulate with consi erable force through the fibers of the material and thereby reduces a veryeficient washing effect. 511' account of the fact that water is constantly flowing upward. in the perforations ofthe'upper roller by ressure, the upper roller in op eration wi l accumulate a quantity ofwater so as to form a bath 22 and the water of this bath is constantly trickling out through.

some of the erfdjgations onto the cloth 21. The line '23 indicates the level of this bath inFig. 1. Obviously this level will depend upon the speed of rotation of the rollers, and if the speed is sufficient the bath will 1 have a high ievel and will .have considerable weight which materially increases the pressuraiof the upper roller on the lower roller.

F a cloth of considerable thickness be folded up within the folds Inthis waythe hollow cylindrical form of the roller is utilized to give lightness to the roller when themachine is being transported, and gives weight to the roller when it is in operation. 4 The machine operates most effectively on such as a blanket; Where thin cloths are to be washed, they are preferably folded into considerable thickness beforevlveing passed between the rollers. Where ery small or dainty articles are to be washed, they can of a towel or cloth and the cloth then passed throu h the machine. The washing effect is ufiicient to wash all the articles in the interior of the folded cloth. The lower roller is preferably of somewhat smaller diameter than the upper roller as the thickness of the cloth eing washed virtually increases the di- :ameter of the lower roller. The corrugations 16 and 17 assist in giving the rollers a form or embodiment the invention may take, and I do not wish to be limited in the practice of my invention, nor in my claims, to the particular embodiment set forth above.

What I claim as new is 1. A machine for washing textile fabrics comprising a washing member having a surface with a plurality of circumferential rows of cup-shaped pockets, and a second wash- 111g member cotiperating therewith to compress the wet fabrics into said pockets, said pockets having perforations to permit the escape of the water exprcssedirom the fabric in said pockets.

2. A machine for washing textile fabrics comprising a washing member having a surface with a plurality of cup-shaped pockets, and a second washing member having a surface with pockets into which the fabric is compressed and which exert a suction on the fabric as it withdraws therefrom, cooperating with said first member to compress the wet fabric into a plurality of said pockets, said pockets having perforations to permit the escape of the water expressed from the fabric.

3. A machine for washing'textile fabrics comprising a washing member having a surfaeeewith a plurality of circumferential rows of cup-shaped pockets, and a second washing member coiiperating therewith to compress the wet fabric into said pockets, said pockets having perforations to permit the escape of the water expressed from the fabric in said pockets, and means for resiliently pressing one of said members toward the other. 4:. A machine for washing textile fabrics comprising a roller having acylindrical shell with an inwardly offset wall forming pockets therein, and a washing member ,coiiperating therewith to compress the wet fabric into the pockets, said pockets having perforations in the wall thereof permitting the expressed ater to pass into the interior of said shell.
