I Renewed'SeDtember 29, 1933 24 Claims.

This invention relates to washing machinesgenerally and in particular to washing machines adapted to provide a plurality of separate washing compartments which may be used selectively '-or simultaneously at the will of the operator.

' Prior to' my invention some of the more expensive washing machines provided means for regu- '-lating the speed and in some cases the stroke of the machine in order. to efliciently and safely wash diiferent kinds of articles, that is,' for rough and heavy work themachine would be run at a relatively high speed providing a strong agitation ing of fine silks and other fragile articles a less violent degree of agitation is desired in order to prevent tearing and undue wear on such articles when subject to the washing operation and when washing such articles the machine would be run at a slow speed or short stroke.

Washing machines of the type just described while providing a flexible machine capable of accomplishing the desired res'ults areobjectionable in that theyare relatively expensive and complicated, restricting their use and sale to the high price field of purchasers.

It is the object of this invention to combine in a single inexpensive washing machine a plurality of washing compartments adapted to be operated by a common means whereby the fluid in the individual compartmentsof the machine is agitated at different degrees of intensity and whereby at one and the same time difl'erent articles requiring difierent washing treatment may be washed at the same timesand whereby the different compartments may be used singly or together at the will of the operator and whereby separate and distinct detergent solutions may be carried in individual compartments of the machine for the separate washing of difierent classes of articles.

A further object. of this invention relates to certain improvements in method and apparatus 'for the washing of clothes whereby the clothes unfurled, flexed:and acted upon piece by piece and part by part durlngthewashing operation.

. action for their cleaning.

Stated in general terms, my invention consists in replacing the usual agitator member. of a washing machine with a hollow agitator, the interior of which is adapted to provide a separate washing I compartment and in which a 'difierent or the same detergent solution as carried in the tub may be used, the exterior of the agitator cooperating agitation of thecontents thereof.

1 The washing action within the agitator is less violent than the action in the tub and the in- 'terior of the agitator is particularly adapted for with the tub in the ordinary manner for the the tub may be used for the washing of heavier and coarser articles requiring a more violent With these and other objects and advantages in view, the invention consists of the novel construction arrangement and combination of parts hereinafter described and illustrated in some of its embodiments in the accompanying drawing and particularly pointed .out in the appended claims. I

Referring to the drawing, Fig. 1 is a side elevational view partly in section of a washing machine embodying my improved agitator. 4 Fig. 2 is a plan elevational view of a modified form of agitator adapted to replace the agitator shown in Fig. 1.

Fig. 3 is a side elevational view of the agitator shown in Fig. 2. Fig.4 is a plan elevational view 'of another form of agitator adapted to replace the agitatorshown. in Figs. .1 and 2, and Fig. 5 is a side elevational view of the agitator shown in Fig. 4.

For the purpose of illustration I have shown my improved agitator in connection with a conven tionalgyrator.typewashing machine having a base I in which is'housed a suitable motor (not shown) I connected to gear mechanism within the case 3 by means of a belt 4. A tub 2 is supported on the base l of the machine above the gear case '3. A drive shaft having a splined head 6 projects through the bottom of the tub. This shaft is adapted to be driven by the motor through suitable gear mechanism in the case 3with an alternating rotating movement as is customary.

The'shaft and head 6 are adapted'to detachably support and drive through the cooperating element if an agitating member 5 which in the present case comprises a cylindrical hollow member havingbaflled plates 1 located in the bottom -thereof and vertically disposed ballie plates 8 located exteriorly thereof. A cover, 9 having'a ti n. The interior ,oi'jthe element! is"ada'pted,t'o be used for the washing of small and fragile articles provide a means for the agitation of the liquid,

and the space between the agitator 5 and the tub 2 is adapted for the washing of heavier and less fragile articles. -By reason'of'the'construc washed from working beneath the inner container and beeoming'tangled and torn, as would probtion shown agitation within thecontainerj is relatively gentle as compared witlr'theits tatio'nproduced in the annular space defined bythe tub 2 and the container 5.

Furthermore; it is to be noted that detergent fluids of different strength may be readily used in-the difieren't compartments so that it is possible and two different washing-actions are s'ufllcient' to take care of most any article to be washed The modified forms of agitator shown in Figs. 2 to 5 inclusive are provided with containers of irregular outline so that the side walls of the container take the place of the agitating members or baiiles I and 8 of the device shown in Fig. 1.

Referring to Figs. and 3 wherein is shown a container having a base plate ll supporting an irregularly shaped container with inner and outer notched edges l3 and I8 which are adapted to i? the tub as well as that within the container i self.

During the washing operation of this form of agitator the notched walls of the container, due to their ratchet-like configuration, serve to move theclothes and liquid outside the container continuously in a clockwise direction while at the same time moving the clothes and liquid inside the container continuously in a counterclockwise direction. By reason of this mode of operation, all of the articles being washed both inside and outside the container'are subjected successively and repeatedly to the washing action of the notched edges 1 I and l I.

In the modification shown in Figs. 4 and 5 a plate l'l similar to the plate H of Fig. 2 is used. In this modification the contour of the container is slightly different the wall I! being shaped to provide 4 blades l6 which function during the operation of the device to agitate the liquid of the tub as well asthe fluid contents of the container.

. From the foregoing it will be apparent that I have provided a single tub washing machine hav- .ing aplurality'of compartments adapted to provide for the washing of diiierent kinds of articles .ing action consists primarily in rubbing and scrubbing the clothes; In place of corrugated rubbing and scrubbing surfaces of the type shown -in Lockh'art Patent No. 311,133, the agitating devices in the present invention exhibit liquid impelling surfaces of substantial size which are circumferentially spaced apart from each other a susbtantial distance so as to act upon separate and distinct portions of the contents of the compartment and vigorously agitate the same during the operation of the machine.

The bottom of the inner container is located closely adjacent to the bottom of the outer container or"tub*so"as-to prevent the articles being ably be.the case if one were to attemptto use a churn of the type shown in Truitt et .al. Patent No, 1,737,265 for the washing of clothes.

If desired the complete washing operation may "be done inthe removable container 5 as where the articles to be washed are few in number or are of such kind as tovrequire the gentler action of this device. In such c'ase'it is not necessary to fill or empty the relatively large tub 2.

Due to thesmall size of the container. 5 it may be readily removed from or replaced in the tub 5, further facilitating the washing operation and permitting at the s'a'metime the use of cleaning fluidssuch as gasoline and naphtha which would be dangerous to use 'in the open tub 2. When used for dry cleaning purposes the'articles to be cleaned and fluid are placed in the container in some safe place such as out of doors and the cover 9 securely fastened in place. The container 5 is then carried to and placed in the washing machine where it may be agitated for the desired length of time and then bodily carried to a safe place for the removal of the cleansing same manner as the more usual form of blade 8' carried by the container 5.

In the operation of the device illustrated in Figs. 2 and 3, when the container is moved counterclockwise, the liquid adjacent to the notches is given a spiral motion in a horizontal plane and thrown outwardly at the same time and when the device is rotated in a. reverse direction, the clothes are sucked inwardly behind the blade formed between the notches l3and lit with a reverse spiral motion to that just mentioned. During successive operations of the device, clothing and liquid move in a well-defined path about the vat in one general circulatory direction with an intermittent retardation for each counter,- clockwise movement of the agitator and as,the clothes are worked upon in this manner, they are separated, unfurled and flexed as they come into the zone of action of the agitating surfaces of the device and in this manner a, uniform and thorough washing action is secured which may be for washing. purposes from the top liquid level to the bottom of the vat or tub and in the device referred to as individual action on the clothesv as distinguished from collective action in which are presented for purposes of explanation and shown iii-Figs. 2 and 3 they define channels extending downwardly from the top surface of the liquid toward the bottom of the vat.

While I-have'shown my improved washing 'device in connection with a gyrator type washer to which typepf machine it is particularly adapted,

it is apparent that such device could be readily adapted to other types of washing machines.

Furthermore it is 'to.be understood that the particular forms of apparatus shown and de-- scribed and the particular procedure set forth that various modifications 'ofsaid aparatus and procedure can be made without departing from my invention as described in the appended claims.
