WASHING AND Dianne MAGHINE Apaiicauon med Haren 2o, 192e. serial No. 96,357.

The object of this invention is to provide a machine especially adapted for use where space is limited, and where a machine at moderate cost is desired. j

6 A further object is tol providea machine` comprising a. main receptacl. adapted to i house a cage for receiving the clothing, a propeller `mounted beneath the cage, and independently mounted electric resistance-units 1'0 adapted to elitend into the space between the cage'and the walls of the receptacle, these units each includingan outer casing, for use vwhen the receptacle contains water for washing purposes, the casings` of the separate resistance units being removable however when the water has been drained oi and the clothes areto beldried. l A .further object 4is `to provide special meansfor mounting and'drlving the movable elements.

With the foregoing and other objects in view, the invention consists in the novel construction and arrangement of elements described, illustrated and claimed, it being unr derstood that modifications may be made Y within the sco )e of the claim, without-de parting from t e spirit of the invention. In the drawings forming part of this application,

Figure 1 is a top plan view of the machine. Figure 2 is a view in verticalsection on the line 2-2 of Fig. 1.`

Figure 3 is a horizontal section, below the cage element.

Figure 5 is a detailin section o n the -line 5-5of Figure 3.

The mam receptacleor tub isddesignatedv 10, and includes the concave bottom 11, rest- The cover 18 1s apertureid 'for the accommodation of electric heating units, such as 20, and a handle21 of'bail form, serves 'an obvious purpose,'being provided with a cen- '5 tra-uy located hand hola 22. 1

Figure 4 shows one of the resistance units, in elevation, a portion being broken away.-

The elements 20 are shown in detail in Figure 4, and each orf-these devices includes a tube or casing C having threaded connection at 23 with mounting means 24, the latter constituting an element of a two vpart plug of 5t commercial type. The -other art' of this lug .is designated 25 and inclu es the usual ngers 2 6. The resistance elementper se is j designated 20', and the heat radiated therefrom passes thru the walls of the casing, when 6u the latter is employed, that is when the y'receptacle is filled with fluid, or contains water for washing purposes. When the resistance units are employed for drying purposes, the Water having been drained off Vfrom the re- 6F ceptacle by means of pet-cock 28 controlling an outlet 29,-the casings of the resistance unitsare removed. Y

A vertical shaft 30 is driven thru suitable gearing by motor 31, and this' shaft 30. 7u

passes thru a boxing 32 in the bottom --of the tub, and 'is threaded into a socket 33, the socket constituting the hub of a propeller designated 35 and including a desk portion and integral blades 36, of the form shown in Figure 5 in cross section. It will be observed that the blades are radial and are inclined uplwardly with 4reference to the diskon. w ich they are formed. A thumb screw 3T is threaded into element 38, the screw passso ing thru the bottom member4 or transverse member 401secured at 41 to thevertical walls of the cage 42. The latter -is 'preferably circular in cross section, and constitutes a clothes receptacle, it being noted at this 'su point that the housing 10, or water recap- 'y tacleis illustrated as being of rf'ectangularvl cross section.

f A terminal box is designated 45, and is.'

adaptedto receive elements such as.46 for -so connection-.thru conductorsf47 with vthe eleconducting means 48 with the lower element 9 5 46 in the terminal box, andconnections for Lanyelectrical appliance can also readily be;

made from this ox.

In'connection with t e propeller, it will be observedlthat a'por ion'roli the edges of 10o each blade project beyond the edges of'adjacent blades leaving spaces thru which suction takes place.

Several of the blades 36 of propeller 35 are connected with the bottom by thumb i screws 37', as shown in Figure 2, the apertures for the screws being shown at 36 in Figure 3. cludes gear wheel 5 on the main shaft ot' thc motor, wheel Wheels 7 and 8 meshing with the Wheels first named and arranged in this manner to provide a balanced drive.

The clothes are placed Within the cage or container 42, the main receptacle or tub l() is filled with Water, and current is supplied to the motor and to the electric resist-ance units 20 inclosed in their outer casings, for

protection from the Waten The cage being rotated by the motor, shafting, and gearing, by means of which the propeller is also rotated, the Water will be agitated and will pass around and thru the cage While the latter is moving, and the clothes will be cleaned because sufcient force is applied to the Huid to drive it thru the cage.

For drying purposes, the Water is merely drained oi and the casing of the separate resistance units removed, so that the drying operation may be performed by the air current developed by the propeller acting as a fan, and heated by the resistance elements.

Having thus described the invention, what is claimed as new is:

In a device of the class described, a receptacle including a bottom, a rotatable perforated clothes container Within t-he receptacle spaced from the bottom thereof, a device in said space, comprising a disk provided with upper and lower integral hub portions, a plurality of radial and inclined blades connected to the upper surface of the disk and contacting at their upper edges with the i bottom of the container, a driving shaft extending through the bot-tom of said receptacle and connected to the lower hub portion, and means for detachably connect-ing the bottom of the container with the upper hub portion and the upper parts of certain of the blades.

In testimony whereof I aix my signature.
