To all whom t mag/concern.'

'Be it knownthat-1, llinniswi HANSEN, a citi-zen of `the United States, residing fat Chicago., kin .the county of Gool: land State *5 of Illinois, have invented certain new -and usefullmprovenients in Ahashing Machines, of whichthe follow-ing is r-a specification.

The present in'veiirtionyrelates k:to improvements in domestic washing machines, now 'infgeneral use inhouseholdsas wjcll as laundering establishments, wherein the yclothes `are introduced into f an -ioscil-lating, revolving orsimilarmovable receptacle and -agitated for a suitable length tot vvtime to -reniovethefsoil. v

The ieicacy r'of @processes of cleansing fby these 4`manu-ally fand mechanically 1 operated devices veryl greatly depends upon lthe i fprer'lim-ina'rytreatmenty of' the clothes, 4unless the expedient 'of'use `y of chemicals is lresorted to which is .not `in any way desirable in -vie'w` of the deleterious effect 1upon the 4-fabrios. -Thatslis ftofsay, it v`is {qui-te customary Kto 'place thefs'oilediolthes in soak overn-ight or for a `considerableperiod of )time fpreliminaryto washingtthem in order that the dirt `inay :be fsoi'tened aandf inoreeasi ly Ybe fremoved whenthe-clothesfare agitated 'in the washing operation of the apparatus. However, even with this :preliminary treatment, it is l. practically necessary-to resort Ito spotrubbing,`-that is, rubbing `of the soiled spots by hand-.upon anfordinarywashboard, or rubbing such spots between the hands "rather atiringvprocessl and fit-zhasytliere'fore, been my object to facilitate the initialrubjunction with the washing apparat-usthereby `further eliminating- Ithe ldrudgery Vat- `tendantupon the washing of clothes -as generally practiced. j

Corresponding and-like parte arereterred to in thejfollowingv ldescriptibn and "indi- 195 cateolin `all ci the rviews o'f-the drawings vby like-referenceA Characters.

Referring to the drawings, i and'particularly Figures 1t-to V3,-1indicates-[the `awt-er receptacleor-tankota conventional form ot' `100 washing machine rin, Awhich is" jijou'rnaled the --rotating foroscillating `clothes cylinder or `drum 2. Uponthe baseotthe machine is mounted thei motor 3- having the drive shaft 4 thereof extending Y into fthegear case 5. A105' A shaft 6 Iextends tromfthisV gear case upwardly to the :axis lof thezcylilnder 2i --fto which f it is -f operatively connected Jfor the 4purposedf actuation o-Itliecylinder in the.

2 vMedea? At one side of the receptacle l is formed an extension or auxiliary compartment '.7,

tuated from the motor 8 having mounted at lone side therein a rubbing cylinder 8 over which extends an apron t) provided with an opening l() exposing a portion of the surface of the rubbing member. The surface of said member is ribbed or corrugated, as clearly shown in the drawings, so as to provide a rubbing action in the use of the invention as later described. The partition wall between the compartment 7 and the main receptacle 1 is provided with one or more openings 1l through which the water from the main compartment may pass to the auxiliary compartment and seek the same level as in the former. lIt will be apparent that in the drainage of the water from the washing machine the usual drain, not shown, will carry off the water from both the main and the auxiliary compartments by virtue of this communication. Extending from the gear case is a shaft l2 which is operatively connected with the shaft 13 on which the rubbing cylinder S is carried, said shaft being journaled in the ends of the auxiliary compartment 7. A clutch element 14 is provided whereby the shaft 13 may be acat will as and when it may be desired to employ the rub bing device for the purposes inten-ded.

In the use of the apparatus, the clothes which may have been previously soaked are spot-rubbed whenever foundv necessary by soaping the part which it is. desired to cleanse and holding this portion of the fabric against the exposed surface of the cylinder 8 while the latter is rotated. The clothes as rubbed may be allowed to stand in the auxiliary compartment iffthe clothes cylinder in the main compartment is op-Y erating or may be directly thereafter placed in the clothes cylinder 2 if the latter is not beine' operated at that particular time.

The apron 9 forms a support for the clothes which are being held in rubbing position and prevents the clothes from becoming entangled about the cylinder during the rubbing action. Passing now to the formdisclosed in Figures 4t and 5, it will be observed that this constitutes a similar arrangement excepting that the rubbing cylinder 8 is arranged at right angles to the position vshown with respect to the form disclosed Vin Figure l. lith this arrangement a counter shaft l5 is employed to operatively connect the rubbing cylinder with the driving means extending from the drive shaft Ll. By virtue f this arrangement of the cylinder the apron 9 is given a different configuration but serves the same purpose as Ydescribed with reference to the `)referred form.

In Figure 6 I have illustrated a cylinder in which the ribbing is arranged differently from that disclosed in the figures hereinbefore referred to, the ribs having a diamond shaped arrangement at each end of the cylinder 8 which arrangement would afford an excellent rubbing surface for an apparatus of this type.

Passing now to Figures 7 and 8, it will be not-ed that they depict a rubbing device of an entirely different type, being disklike in form as indicated at 8a, the apron 91 being provided with a circular opening 10 exposing the flat surface of the rubbing member its full extent. This surface is either provided with a rib arrangement such as shown in Figure 7 or a similar rib arrangement as shown in Figure 9 and the member 8fL is rotated by means o-f the shaft 16 from the drive shaft in an obvious manner.

It will be understood that the ribbed surface of the rubbing device may be of metal, glass or wood and'I do not wish to be limited as regards thematerial which may be employed for this purpose.

It will be further obvious that the provision of a rubbing instrumentality of this nature in conjunction with a Washing ma chine embodies a very useful combination of elements for performing the ordinarily laborious operation of washing clothes.

It is within the purview7 of this invention, however, to employ theidea without regard to a direct attachment to or combination with a clothes washing machine, because a machine of the principles of my rubbing device would serve to accomplish the rubbing of clothes mechanically in performing the washing operation after the usual manner.

I desire' it to be understood that the rub# bing device may be applied to washers of different constructions from that disclosed herein and other changes in details of the arrangements may be made without departing from thespirit of the invention and within the scope of the claims hereto ap- Vpended. Y i

Having thus described my invention, what vI claimVA as new and desire to secure by Letters Patent is: y

l. A combined washing and rubbing machine comprising a water receptacle, a clothes receptacle therein, means for actuating the same, an lauxiliary water compartment supported upon the water receptacle andcommunicating therewith to establish a common v'waterleveh' a rubbing device in said compartment, and operating means for said device. V y

2. A clothes rubber comprising arecepta` cle, an exposed rubbing member mounted therein and having its surface formed with ribbed elements to impart rubbing action when they clothes are manually pressed against the same, an inclined guard apron and support for the clothes adjacent said member, and means for actuating saidrubbing member. Y

3. In a clothes rubber of the class described, a receptacle, a rubbing member mounted thereon, means for actuating said rubbing member, and a shield extending from the base of the receptacle to said rubbing member and forming a clothes compartment in which the clothes are protected from the rubbing member.

fl. A combined Washing and rubbing,` machine comprising a Water receptacle, a clothes receptacle therein, means foractuating thesame, an auxiliary water compartmentA extended from one side of the water receptacle and communicating therewithl at its base to establish a common Water level in both the Water receptacle and compartment, a rubbing device in said compartment and operating means for said device.

5. In a Washing 1nachine,va Water receptacle, means for agitating clothes therein, Van auxiliary Water receiving compartment communicating with the first mentioned recep-V tacle to provide a feed and drain connection to said compartment, a rubbing device mounted in said auxiliary compartment, and means for actuatiing said rubbingv device.v

In testimony whereof I affix my signature.

WILLIAM HANSEN.
