wasnme MACHINE.

Application filed May 23,

fluid is effectively circulated through the' clothes containing receptacle so that the clothes therein will be thoroughly cleansed.

Another object is the provision of a washing machine of simple and practical construction. 9

The above and other "objects will appear more clearly from the following etail description, when taken in connection with the accompanying drawings, which illustrate a preferred embodiment of the inventive idea.

In the drawings- Figure 1 is'a side elevation ofthe machine constructed in accordance with the invention; 7

Figure 2 is a fragmentary vertical sectional view with parts broken away to show the interior construction;

Figure 3 is a top plan view of the cover of the machine removed; and

' Figure 4 is a perspective view, partly brokenaway and shown in section, of a portion of the impellingl mechanism employed in connection wit the invention.

The form of the invention shown in the accompan ing drawings comprises an outer casing 5v aving a removable cover 6 and supported in an elevated position by means of legs 7. The bottom 8 of the casing is inclined and provided therein with an outlet 9 controlled by a suitable valve 10,

which may be opened to permit of drain ing the water or other cleansing fluid from the casing. Centrally of the bottom-8 the same is provided with an inwardly and upwardly .extending bushln 11 for receiving the vertically arrange driven shaft 12 having an intermediate bearing 13 and a lower bearing, conventionally shown at 14, the latter bearing bein carried by a slugporting shelf 15 secure to the le s 7 e shaft 12 is further provided wit a bevel 1923.

gear '16 meshing with a similar gear 17 carried bythe shaft of an electric motor or other suitable drivin means 18 supported upon the shelf 15 and operable to rotate the shaft 12 in either direction.

Supported by the upper end of the shaft 12 and within the casing 5 is a clothes re*- ceiving receptacle, generally indicated by the numeral 19, and including the bottpm 20 having an outwardly and upwardly 1nclined portion 21, from the outer edge of which extends the vertical side 22 havin a plurality of perforations 23 through whic water may be discharged from the receptacle during the operation of cleanin drying the clothes. The top 24 of t e receptacle 19 is provided therein with an opening 25 through which clothes may be inserted into andremoved from the receptacle. The bottom 20 of the receptacle is and provided with an annular row of openings a 26 through which the cleansing fluid from the casing 5 is'injected into the receptacle by the impelling mechanism presently'to be described.

The impelling mechanism preferably comprises a plurality of bafile blades or plates 27 havin their inner ends secured to the bushing 11 and extending radially therefrom, the outer extremitles of said blades having the projections 28 which rest upon the bottom of the casing, thus forming openings 29 beneath the blades throu h which the water may circulate when eing agitated by the rotating portion of the impellmg mechanism carried by the receptacle 19 and hence driven by the rotary shaft 12. The rotating portion of the impelling mechanism includes'the outer and

inner walls

30 and 31, respectively, depending from the bottom 20 of the receptacle 19 i and arranged on opposite sides of the row openin 26 so that said openin will be dispose between said walls. he inner wall 31 is arranged beyond the outer ends of the blades 27 and is of less depth than the outer wall 30 so that the lower edge of said inner wall will be approximately in a plane with the upper ed of the blades 27 thus permitting of a co circulation of the water in the casin as the impelling mechanism is rotated. etween the walls 30 and 31 a plurality of impelh'ng blades 32- are mounted in inclined position relative to the walls and in substantially parallel relation with respect to each other; By thus arranging the blades diagonally with respect to the axis of rotation of the impelling mechanism, it will be obvious that, with said mechanism is rotated in a clockwise direction, the water in the casing 5 is thoroughly agitated by the cooperation of said bladeswith the bafl'le blades 27 and quantities of said water are conveyed upwardly by the blades 32 and through the openings 26 in the bottom of the receptacle 19. After entering said receptacle the water is thoroughly circulated through the clothes therein by the centrifugal action, due to the rotation of said receptacle, and finally passes through the openings 23 from whence it falls back into the casing.

After the receptacle and impelling mechanism have been rotated sufliciently to cleanse the clothes in the receptacle the shaft 12 may be rotated in the opposite direction by reversing the motor 18. By thus reversing the direction of rotation of the receptacle the blades 32 will no longer operate to convey the water upwardly and through the openi s 26 owing to the pitch of sand blades and ence the rotation of said receptacle will merely operate to discharge, by centrifugal force, the water from the clothes until the same are dry or substantially so.

What is claimed is:

1. In a washing machine, a casing, a rotatable clothes containing receptacle therein having a plurality of openings in the bottom thereof, an impellmg mechanism associated with said receptacle and including baflle members supported by said casing and extending centrally therefrom to points short of the wall of said casing, spaced concentric walls depending from the bottom of said receptacle and arranged on opposite sides of the openings therein, the inner one of said walls being arranged outwardly beyond the adjacent ends of said baflle members, and means disposed between said walls and cooperating with said baflle members to agitate a fluid in said casing and convey said fluid from the casin into said receptacle through the openings in the bottom of the latter.

2. In a washing machine, a casing, a rotatable clothes retaining receptacle therein having a plurality of openings in'the bottom thereof, an impelling mechanism as sociated with the receptacle and including baflle members supported by said casing and extending centrally therefrom to points short of the wall of said casing, the outer ends of said baflle members having projections engageable with the bottom of said casing to provide openings beneath said members for permitting a washing fluid to circulate therethrough, spaced concentric walls depending from the bottom of said receptacle and arranged on opposite sides of the openings therein, the inner one of said walls being arranged outwardly beyond the adjacent ends of said bafile members, and means disposed between said walls and 00- operating with said baflle members to agitate said fluid in said casing and convey the fluid from the easing into said receptacle through the openings in the bottom of the latter.
