the apertures in the periphery of the cylinder I eifect a cleansing f during rotation of the latter to action.

It is a general object of the present inven-vV tion to provide an improved construction wherein there is no outer shell containing water, and wherein a washing cylinder, rotatable on a horizontal axis 'and having a 'peripheral wall whichV is imperforate throughout the major portion of the axial length'of thecylinden'contains both'th'e l water and the garments to be cleaned,A there being means' on the inner side voi .the peripheral wall of the cylinder for agitating and lifting the water to splash `the same upon the garmentsand Il.'

as the cylinder rotates, with all the water con@` fined in said cylinder.

A further object of the invention is to provide I' improved means for effectively lintroducing water or dry-cleaning duid into the interior ofthe lcylinder and for discharging the spent liquid.

A more 'specific object of the invention isto provide a washer as above described, having an imperforate peripheral wall,v wherein there is an:l aumliary discharge chamber at one end of the drum separated from the main washing chamber bya perforated wall, there beingl hollow perforated garment lifting ribs' in themain washing chamber terminating at one end at said perforated wall, and there'being means housed in f said auxiliary chamber for conducting waterv orI cleaning fluid directly into said hollow ribs so 1- thatthe liquid is ultimately discharged radially inwardly from said hollow perforated ribsiand". onto the garments within the washing chamber. f

.ii-still further object of theinvention is .toa-

provide a washer as above described wherein` the water or cleaningl fluid is 'iirst introduced axially into the auxiliary chamber and theny With the-above and other objects in view. the,l invention consists ofthefimproved washing ma-`l` chine, andfall' its 'partsjand combinations as set iorth'inthe claims and all equivalents thereof. Inthe accompanying drawing, illustrating" one` complete 'embodiment ofthe preferred form of the invention, in whichv thev same reference nu i merals designate' the sameparts sin all ofthe -viewsz t -1 Fig.' v1' 'is a vertical.l section-takenaxially vof .the t :1 drum andillustrating the improved washing mal ;y chinezand c' Referring moreparticularlylto the drawing, the i numeral B designates4 a suitablesupportingfirarne.` I having ibase members 9- y'and supporting legs;` lllv suitably :supported 1 on the baser are; 4 upstandin'g-'bearingimembers vI2 on one side land s; I 8 on the otherside.

Any suitable arrangement maybe utilizedior causing yrotation Aof the drumon the.'V rollers I B f and I1.M` As 'onev method of ,accomplishing this., function, there' is anelectric e motor. 18,. or.l other f prime mover, havingitsv drive-.shaft I9. provided .f with'abevelgear 2i on a-horizontal. shaft 22.11; The 1 horizontal shaft. 22 is vadapted to drive through a Worm and Jwormwheel connection, the .l shaft Il. The forwardendof the shaft I4 is;'r equipped with a rigidly mounted sprocket wheelv which is connected by an endless chain 24 with f a sprocket wheel mounted rigidly on the-forward j end of the other shaft l5. Thus; operation of the; motor I8, in a desired direction, causes simul- I taneous rotation of the tw'o sets 'of'dr'um sup-'-l porting rollers` IB 'and l1. 'If desiredfany well-'1 known mechanism may be employed vto cause the drum to oscillate rather than rotate continually .t :t

inthesame direction. Y f ,t In.

The washing cylinder or drum v28 is mounted for rotation -on aihorizontal axis. This drum is equipped withtexternal peripheral tracks 21 and for removing spent liquid which has circulated from the washing chamber, through the perforated. wall. and into said auxiliary discharge chamber.

is supported .for rotation on the rollers I8 and. I1. The rollers yengage within thetracks, as shown in Fig. .1, vto cause rotation gir other movement of the drum.

The peripheral wall portion 26 of the4 drum is -impel'forate,- andthe front end. wally!! kis, providedlvyith` a loadinaopening d25 whichrianore 55 mally closed by a door'. At the opposite or sectional'` view onrthe* line f I.

inner end of the drum is a wall 3| formed with perforations 32 therein. These perforations prei'-` the entire wall except for the centers portion thereof. Supported on the inner surfacel erably cover of the peripheralwall portion 26' and extending between the end wall 28 and the perforated wall 3| are a plurality of hollowl ribs 33. These ribs are adapted to lift water or other liquid in the; lower portion of the cylinder, as the cylinder rotates, and splash said liquid back on the gar-` ments. The ribs also keep the liquid in an agltions 34 for a purpose tobe hereinafter exp1ained.

The openings garment lifting ribs. After the drum has been tated condition and serve to keep the garmentsl in motion. The ribs are also formed with perfora-` 32 vin the perforated wall 311v communicate withy an auxiliary discharge cham-` 'ber 35 and said discharge chamber has an imperforate end wall 36 which is spaced .from the perforated wall 3|. The auxiliary discharge chamber also has a peripheral wall portion 31. i

A sleevel 38, which `is suitably supported against rotation, extends axially into an opening 39 in the end wall 36. The sleeve 38 may be provided with an annular flange 40 within the auxiliary discharge chamber 35. AAny suitable sealing means may be utilized to prevent loss of` liquid through the opening 39 around the sleeve,V 38; Extending axially to the sleeve 38 is a sup-3 ply conduit 4| for fresh water, soap, steam, orI

, dry-cleaning fluid. The inner end of the supply ferred to have the conduit portions 43 connect with other conduits 44 which extend longitudinally within the hollow garment lifting ribs '33. The conduit portions 44 are provided with liquid discharge openings 45. i

A discharge conduit 46, which extends longitudinally through the sleeve 38, communicates with a suction pipe 41 which'extends radially within the discharge chamber 35. The lower end 48 of the pipe 41 is open and positioned near the periphery of the chamber 35. The pipe 46-may connect with a suitable suction pump 46'so that spent liquid may be removed from the discharge chamber 35. This used liquid may, if desired, be

reconditioned in any well-known manner and recirculated. f

During use of the improved washer, the garments to be cleaned are first positioned within v. the washing chamber and the door 30 is closed. Next, the motor I8 is started to cause rotation or other movement of the drum 26. Hot water and soap, or a suitable dry-cleaning uid is directed through the inlet pipe 4| under pressure. From the pipe 4| the cleaning liquid flows radially outwardly through all of the conduits 43 at the same time. .The liquid then enters the longitudinal conduit portions 44 and is discharged into the interior of the hollow perforated ribs 33. After these ribs have been filled with liquid, the liquid is forcibly discharged from the openings 34 in the ribs toward the center of the drum. The multiplicity of. small streams of liquid, extending throughout the length of thewashing chamber, will act effectively on the garments withinvthe drum as the garments are .being agitated by the rotation of the drum and by the action of the lled to adesired level with'the washing liquid, some of the spent liquid will continually flow into the auxiliary discharge chamber 35. It is possible to operate the machine .so that fresh liquidi is continually admitted while spent liquidis con# -tinually withdrawn bythe suction pipe 41. It

is also possible to shut off the supply of fresh liquid and to shut orf the suction pumpand permit the washer to operate for a desired period before the used liquid is withdrawn. v

By having the radial conduits 43 located within the auxiliary discharge chamberrf35 and by having the longitudinal conduit portions 44 located withinl the hollow ribs, these conduits will in no way interfere with the garments and will not come in contact therewith. The -construction is inexpensive to manufacture because of the simple method of introducing the washing liquid because' and of withdrawing the spent liquid and no outer shell is necessary.

Various changes and modifications-may be made within the spirit of the invention and Yall o'fsuch changes are contemplated as'may come within the scope of the claims.
