RINSING DEVICE FOR WASHING MACHINS Filed Jan. 24, 1927 Patented May 6, 1930 UNITED STATESl PATENT OFFICE JOSEPH w. nUsx EOBEET E. OLSON, OE Tacoma, WASHINGTON, AssIGNons To SYBACUSE WASHING MACHINE CORPORATION, F SYRACUSE, NEW YORK, COB-l POEATION OE DELAWARE i RIN SING DEVICE FOR WASHING MACHINES i i Application mea January 24, 1927. .serial ne. 162,961'.

.Our invention relates to washing machines for domestic vor family `use and especlally 4to such machines as are power driven. More particularly, our invention relates to the whirling basket, of such a-.washing machine,y in which the clothes may be packed when re-y moved from thewashing section of the machine, and especially to the means for passing 'clear rinsing Water through the.l mass of clothes whereby they Aare freed of allvsoap, and soapyfor dirty water. i

The objects of our .invention are, first, to

, through the mass of clothing'under"-hydrau `lic and centrifugal pressure, thereby preventing any portion of the clothing from stopping the flow of the-water therethrough; fourtlnto provide Vmeans for confining the flowof water to the heightat which the clothes aregpacked,'j`f thereby preventing the waste of water;fifth,V to provide means for supporting and cente'r'`g.v ing the rinsing Vwater supplypipe; and sixth',',jv a to yprovide acheap and "effective-means, of ex` treme simplicity, for conducting the `water to the central axis ofrotation of the clothes.

We attain these and other objects by the devices, mechanisms, and arrangements illustrated in the kaccompanying drawings, in

i which- Fig. 1 is a perspective view ofa washing machine equipped with our improved rinsing device; Fig. 2 is a partial side elevation of the rinsing anddrying portion of the machine, parts of the outer container and of the inner rotating basket being brokenaway to reveal' the interior thereof, the far side of said parts being shown in blank in order to prevent confusion with the near side; Fig. 3 is a vertical section of the center of the upper portion of the apparatus; Fig. 4. is a similar view of the lower portion thereof; and Fig; v5 is a crossis composed of a washing section and a rinsing and drying section. The washing section comprises a tub 1, with suitable Washing or agitating` apparatus therein, adaptedy to revceive the soiled clothes, hot water and soap an'dto remove or dissolve the dirt from the clothes. The batch of wet clothes are then removed from the tub 1 and placed in the annula-r basket 2 Within' the container 3 of the rinsing anddrying section. The basket 2 isxthen rotated and the free suds removed therefromunder the centrifugal action developed therein, the said suds being pumped lfrom-fthe?container,3, through the outlet pipe ans-of the Vpump 5. Then the rinsing "injected/horizontally in a forceful o rjseries of small streams, in the centralr axi' ,f the annularmass of clothing and theforceof the flow, together with the centrifugal-'force developed as soon as the Water engages the rotating clothing, forces this rinsing water outward through the mass of jclothes, carrylng with it all dirty and soapy Water.

The apparatus for pumping the Water out of the container, for supporting and rotating theV basket, and the driving motor are similar to those at present in use in such rotating dryingirf baskets and will be described only it di ers from the present machines or in order to clearly describe the complete machine.

Referring now more particularly to Figs. 2 5, it Will be seen that the cylindrical container 3, of the rinsing and drying section, is securely mounted on the Washing machine frame and is stationary therein, and that it is provided with a; cast cover 6,A hinged to the frame at 7 The cover 6 has a circular fiange 8 which fits snugly within the upper rim of the cylinder 3, thereby firmly attaching the center of the said cover 6 to the machine frame. The said center of the cover 6 is provided With an axial hole and with a pipe 9 fitted therein and extending into the cylinder. The cover 10, of the annular rotating vbasket 2, is revolubly mounted on the said axial pipe 9 by means of a suitable bearing 11. The cover 10 is also provided with a circular ange 12 fitting snuglyV in the upper riml of the said annular rotating basket 2,

guldmg the` Adriving spindle 14. An inverted cup or apron extends down tfrom thenut 13 and forms an air bell above the lower end closure,l of the said cylindrical container 3. A suit able packing box 16 surrounds thespindle Ll;k

An adjustable bearing 18 is prvidedaengages the lower end of the spindle 14. -Agfloating bevel gear 19 is mounted on the spin- `placing it.

said air bell and has a bearing 17 ,belo' dle 14 and meshes with a drive bevel gear 20'v on the drive shaft 21. Thus the basket 2 is supported by the adjustable thrust bearing' 18 and held by thetwo bearings 17 and 11,

and is -rotated by the'gears 19 and 20.

The basket 2 comprises, in its preferred construction, a metallic cylinder with holes 22 punched therethrough, thus providing easy egress for the water from the mass of clothes packed therein.

In our improved basket we provide a central perforated screen tube 23, having relatively large holes 24 therein, said tube 23 being securely fastened in the center of the bottom closure of the said basket 2, and extending axially upward therefrom to the cover 10 of the said basket. A drain hole 25 (Fig. 4) allows any water, which may be left in the tube after use, to pass freely out therefrom and into the said basket. The screentube 23 is made of strong, stiff, material and will therefore permit the clothing to be packed quite tightly in the annular space between it and the outer wall of the basket, without dis- A small guide cup 26 is secured in the center of the lower end of the tube Cil conducted to the machine by means of a suitable flexible hose 28 connected to a bent pipe 29, whose lower end is conical and is adapted to fit fairly tightly in the axial hole and pipe 9, of the cover 6. A long supply pipe or nozzle 30 extends from'the end of the bent pipe 29 downward in the center of the screen tube 23 and its end enters the guide cup 26, above described. This pipe 30 is closed at its lower end and is provided with a number of very small holes or outlet-s 31, extending ractically its entire length, these holes eing preferably arranged 1n two opposite rows, as shown. The pipe 30 does not rotate, `nor does it come in contact withl any rotating portion of the machine except that, if it is not q upper outlets 31 therein,said pipe 32 fitting closely 011 the pipe 30.

Thus it will be seen that, whenthe batch of wet washed clothing isrotatcd by the ro- ,tating basket 2, in which it has been packed, and is positioned above the water linegingthepthecentrifugal force developed therein drives outward all the loose suds and dirty water, andthe pump 5 removes this water from the utsxde '.offthe said basketas quickly as il. Coll 'ts 'nthe. bottolnof the container 3. Alsothat s,.soon as the pipe 30 is inserted in e .9'and the faucet 27 is opened, the waterth'erefrom is forced-out of the many smalloutlets31finav series of jets. or streams of equal volume, from one end to the other of the saidvpipe 30. These jets are not rotating. The tube'23 is separated far enough from the pipe 30 to permit each stream to `spread slightly before it4 reaches the said tube. This tube 23 is rotating and is full of large holes, therefore each stream or jet thoroughly wets the clothes in the entire annular ring op osite the level thereof, the said jets-striking orcefully through ythel holes 24 as the pass. The water thus at oncesoaks intol t e wet rotating clothing and the C011-, tinual supply of such water, under stream pressure, together with the centrifugal force applied thereto through the rotation acquired from the-rotating clothin immediately impels each particle thereo to pass outward through the whole mass of clothing, and carry with it all soapy and dirty waterrremaining therein. Inpractice this rinsing action is so rapid and complete that in two minutes time the whole mass has been thoroughly rinsed and the water flowing therefrom is c ear and clean. This rinsing action is aided by the vfact that the pump 5 keeps the container. 3

clear of all accumulation of water therein, thus permitting the basket 2 to throw ofi' the water from rthe clothing as quickly as it arrives at the holes 22 therein.

lVhen the rinsing has been thus completed, the faucet 27 is closed and lthe pipe 30 removed from the machine, while the rotation of the basket 2 is continued until the mass of clothing has thrown off the excess water therein.

Having therefore described 0ur.invention, what we claim, and desire to secure by Letters Patent is 1.
