This invention relates to dish ,washing machines, injwhich dishes or other articles may .be cleanse by mechanical application of a cleansing uid.

it is an object of the invention to' construct a water sprayer for adish washing machine in such a manner that the cleansing fluid will be circulated fromthe receptacle of the dish washing machine to a nozzle to be discharged, 143 under pressure, upon the dishes or other articles in a wide, steady stream, dishes or articles are thereby efiectively cleanedin a short time. i

Another objectof the invention is to pro: vide a housing on a, side wall of the receptacle of a dish washing machine, which housing has an inlet at the bottom of the receptacle and an outlet nozzle at the upper end thereof, to discharge the cleansing fluid into the interior oi the receptacle, the said fluid being recirculated from the receptacle by an impeller-in the said housing inlet; means being provided on the outside of said receptacle wall to drive the said impeller; and means of connection being arranged between the housing and the driving means in such mam ner as to securely attach receptacle wall.

- Other objects and advantages are to pro vide a dish washing machinethat will be superior in point of simplicity, inexpensiveness of construction, positiveness of operation, and

facility and convenience in use and general eficiency.

In this specfieation and the annexeddrawing, the invention is illustrated in the form considered to be the best, but it is to be understood that the invention is not limited to such form, because it may be embodied in other forms; and it is also to be understood that in and by the claims following the description, it is desired to cover the invention in whatsoever form it may be embodied.

The invention is clearly illustrated in the accompanying drawing wherein,

, Fig. 1 is a vertical sectional view of an endof the dish'washing machine, showing lthesprayer constructed in accordance with all * fmi' nvs t {j Fi'g.-2 is a vertical sectional view of t so that the both to the said ieso. Serial 150.45%,158.

sprayer in the dish washing. machine, showing another form of mounting of the sprayer housing; and

Fig. 3 is a front view of'the sprayer on the side wall oi a dish washing machine.

In carrying out my invention, 1- make use of a receptacle 6 of a dish washingmachine, in which dishes or other articles tobe washed are held. Adjacent a vertical side wall 7 of the receptacle 6 is disposed a combined pump and sprayer housing 8. The lower end of the housing 8 adjacent the bottom 9 of the receptacle 6is formed into a pump housing 11, the inlet '12 of which extends at right angles to the side wal1 ,7. From the pump housing 11 the housing 8 extends upwardly the width of forming a dischargechamber, which is gradually increased toward the per end thereof, as shown in Fig. 3.

up- The front and rear walls 10 oi -the housing 8 are parallel with each other and with the side wall 7.

The upper end of the housing 8 is curved toward the interiorof the receptacle 6 and is gradually reduced in height, to form an elongated, tapering nozzle 13, discharging downwardly and into the interior of the ing the cleansing flui other articles in the machine. In the inlet 12 is disposed receptacle 6, directan impeller 14. I

substantially diagonally 1' d onto the dishes or of a pump, mounted on the end of a drive shaft 16, which extends thru the side wall 7 and is connected whereby it is rotated to drive the impeller 14. The motor 17 is outside of the side wall 7. a The housing 8 and the motor 17 are mounted, on the side wall 7 e by common to both, which do not include any screws, bolts or other similar fastening means. From the housing 8 exteriorly threaded member 18' which snugly fits in an aperture 19 in said side wall 7 This member 18 may be anintegral part of the housing 8, as in threadedly secured intothe rear wall 10 of the housing 8, as at 21 in Fig. 2.

A bracket 22- on which the. motor 17 is mounted in the usual manner, has an interprotrudes an Fig. 1, or it may be means of connections nally threaded base 23 which is screwed upon the external thread of the

member

18 or 21. ,It is to be noted that the base 23 bears tightly against the outer face of the wall 7, and it urges therear wall of the housing 8 into tight contact with the inner face of said .wall 7. In this manner the housing 8 and the motor 17 are secured on each other and are also securely mounted on the wall 7 therebetween, without the use of screws,

bolts, or rivets and the like. The afore-described mounting arrangement also greatlyfacilitates the removal of-the motor 17 and t 3. Ina dish washing machine the com-' of the housing 8 from the receptacle 6.

The shaft 16 extends thru the member 18. In order to prevent the escapement of cleansing fluid past the shaft 16, a packing gland 24 is secured in the outer end of the member. 18 and of the member 21.

In operation the housing 8 is so disposed in said receptacle 6 that the inlet 12 is located below the fluid level in the receptacle 6. The rotation of the'impelle'r let pumps the fluid from the receptacle 6 and forces the 25 fluid upwardly and out thru the nozzle 13,

which latter discharges the fluid onto the dishes in the vreceptacle 6, in a wide, .continuous, steady stream. Thus the cleansing fluid contained in the receptacle 6 is continuously recirculated and the dishes or other articles are washed thoroughly.

' Havin thus described this invention, what I c aim and desire to secure by Letters Patent is z 1. In a dish washing machine, a' receptacle to hold dishes to be washed therein, a combined pump and spray housing disposed adjacent a wall of the receptacle, a rotaa diagonally downwardly directed nozzle on the upper end of the housing; means outside of said wall of the receptacle to drive the said rotary pump;

.means of connection between the housing and the driving means, extending thru the said wall to mount both the housing and the driving means on said .wall, said means of connection comprising a threaded member extending from the housing and thru saidbeing threadedly secured on said member to wall, a bracket on the outside of the wall "ar against the outside face of said side wall to draw the housing against the inner 7 the end ofsaid drivfluid from the receptacle housing; and a nozzle on inlet being mounted on ing shaft to pum into and thru sai thereby to secure the housing adjacent the bottom of 'the receptacle; an impeller blade in said the other end of said housing to discharge the fluild directed to the interior of said recepae e.

and a mountmg for said driving means detachably mounted on the portion of said element outside of said wall so as to draw sai 1i1 nozzle against the inner face of said wa v 4. Means of..connection for a nozzle and a pump driving means in a dish washing receptacle having an opening on a side thereof, comprising an element extending from the outside of the nozzle substantially at ump 1n the end of the housmg ad acent the 40 Bottom of the receptacle,

right angles to thelatter and protruding through-said opening, the protrudin portion of saidelement being-externally t readed, a drive shaft journaled in said element, a. pump'on the inner end of said shaft, a driving mechanism on the outer end of the shaft, and a support for said driving mechanism threadedly engaged with said pro-.
