DISHWASHING MACHINE.

.Applieation filed November 11, 1926. Serial No. 147,731.

The main object of this invention is to provide an improved dish-washing machine which is highly efficient, the water being effectively and uniformly distributed to" the dishes.

A further object is to provide a dish-washing machine having these advantages which is of large capacity. a 1

Objects pertaining to details and economies of our invention will definitely appear from the detailed description to follow. The invention is clearly defined and pointed outin the claims.

A structure whichis a preferred embodiment of our invention is clearly illustrated m the accompanying drawing formlng a part I of this application, in whlch:

Fig. 1 is a fragmentary view of a washing machine embodying the features of our 111- vention mainly in section on line 11 of Fig. 2.

Fig. 2 is a'plan view of the receptacle of the machine with the impeller, dasher anddish supporting basket or rack removed.

Fi 3 is a plan view of our improved impeller and dasher.

F5 g. 4 is a detail section through the dasher blades on a line corresponding to line 4-4 .of Fig. 3.

Referring-to the drawing, the receptacle 1 is provided with a bottom having a central recess or well 2 comprising segmental raised portions 3 and depressed portions 4, these portions being disposed alternately as illus trated. The depressed portions form drain channels to the well and the raised portions form baflles which prevent the water from setting up a rotary motion within the receptacle or break up such motion.

The impeller 5 is supported on the shaft 6 to rotate in this. well. The impeller comprises blades 7' radiating from the hub 7 and the upwardly and outwardly inclined rim 8 on the blades.

Above the impeller is a dasher 9 having inclined blades rotating in a plane above and overhanging the inner ends of the raised portions of the bottom, the impeller elevating the water to this dasher and the dasher throwing it upwardly within the receptacle. The dasher is mounted on the shaft 6.

The bottom of the receptacle has an opening 10 therein through which the bearing housing 11 of the shaft 6 projects. This bearing housing is provided with a suitable packing and bearings, and also constitutes a housing for the worm gear 12' on the lower end of the shaft. The bearing housing is supported on a cross member 13 extending between the legs 14;.

The motor 15 is mounted on a bracket 16 on the under side of the receptacle. The receptacle cover 17 is removably secured to the receptacle. I

A wire rack or basket 18 is provided for the dishes. This rack is made up of a series of concentrically disposed receptacles of different depths and arranged. in stepped relation so that the water discharged by the impeller and dasher is quite uniformly distributed to the dishes, that is, those in the inner receptacles do not obstruct those in the outer receptacles.

A drain cook 19 is provided disposed in one of the depressed portions, the bottom bemg inclined to this drain cock. An operatmg rod 20 is disposed at the side of the receptacle.

Our improved dish-washing machine is, as stated, highly eflicient and is of large capacity.

Having thus described our invention what we claim as new and desire to secure by Letters Patent is: v v i 1. In a dish-washing machine, the combination of a receptacle provided with a bottom having a central well and segmentalshapcd radial channels communicating therewith, an impeller comprising radial. blades and an upwardly and-outwardly inclined rim mounted to rotate in said well, and a dasher having inclined blades disposed above the said impeller with the ends of the blade projecting beyond the said central well.

2. In a dish-washing machine, thecombination of a receptacle provided with a bottom having a central well and segmentshaped radial channels communicating therewith, and an' impeller comprising radial blades having an upwardly and outwardly inclined rim at the outer ends mounted to rotate in said well.

' 3. In a dish washing machine, the combination of a receptacle provided with a bottom having radially disposed alternately raised and depressed segmental portions providing a series of drain channels, said raised portions terminating at their inner edges in spaced relation providing a central recess, an impeller comprising radial blades and an I n J upwardly and outwardly incllned rim mounted to rotate in said recess, and a dasher above said impeller overhanging the inner ends of said raised portions.

4;. In a dishwashing machine, the combination of a receptacle provided With a bottom having radially disposed alternately raised and depressed segmental portions providing a series of drain channels, said raised spaced relation providing a central recess, and an impeller comprising radial blades and an upwardly anchoutwardly inclined rim mounted to rotate in said recess.

In witness whereof We have hereunto set 15 our hands. a
