turbine, while the power, for actuating this turbine'and. for maintaining the flow of liquid to produce the. spray is derived,

through-a centrifugal pump, from an elec-- ftriemotor. I

holes 31 in thefplate' 18. As Shawn in. Fig.

4 these -..holes-are inclined, and the rotor is provided with .a' series of inclined vanes 32 against which r the water discharged through the holes 3Limpinges. The reac- -t1on-of the water against-thevvanes causes rotation of the rotor and of the spray-pipes carried thereby, while, the ,water emerges through the pipes 24 and is conducted thence to the points where it is discharged, as reviously described.

t, has previously-been proposed to pro- -vi'de a. washing inaeaine v -th a rotary spraymg-device, but in such previous mains the rotation of the device has been secured by the reaction of theliquid in issuing throughthe spray-orifices. Such an I arrangement has the. disadvantage that it is-necessary. to direct the jets at a suitable angleto produce-such rotation. By causing. rotation of the spra pipes by means independent-0f the reaction of the liquid in the spray-o nings, is possible, in the present mac 'ne,.to arrange these openings at the angles most suitable for projecting the'spray with the maximum effect against the articles. Thus, as shown in Fig. 7, some of the openings in the vertical pipes 25, may be directed in the direction of revolution of the'pipes, thus causing the spray to impings at an efifective angle against surfaces which mightnot be reached by-the oppositelydirected sprays.- V j 'lnorderto wash the articles on the hasket 16, it is desirable to project the spray "upwardly throughthe bottom of the basket. For this purpose two of thespraypipes are arranged to carry inwardlyextending horizontal spray'pipes 33. These a, short vertical 3 I which loosely embraoeshndturns on th 1 1'prlattei pipes are perforated, {as shown in Fig. 2, on their upper surfaces, and are closed at their adjacent inner ends. When the basket-'17 is to- 'be .i-ntroducedor re- ,imoved from the machine, together with its contents, it is necessary to move the spray pi s 33 outof the way, and provision for 'th1s'is'"m'ade by connecting these pipes piv o tally .with the pipes 25. As shown particularl in Fig. 6, ,the' spray-pipe 33 has per :extremity of] the-f fcorre sponding pipe 25.. A slot 35 in. thef'sl'e'eve '34 is engaged 33 isin itsiiormal operative position, as

, When ,it is, necessary to f clean the: mac 'ne .liquid tbn dldHllng back-, .into .the bottom oil the casin and thus being repeatedly circulated by t e-pur'np. For this purposean outlet opening 39. is provided in the bottom of the casing, this opening delivering the liquid intoa chamber 40 formed integrally in a casting which constitii ts the forward raid notch, and I the' piple finay theii be swung eve 34 at it'siouter end, I Y

To prevent the spray-openings from becoming clogged by matter washed from the dishes or other articles, it is necessary tostrain the liquid before it'is delivered to the spraying-devices. For this purpose 9. cy-

hndrical strainer. 42 of wire-gauze or other .foraminous materialis arranged as shown in Fig. 1, the upper end of the strainer filling the outlet-opening 39, while the lower end is seated in'an annular seat 43 near the bottom of the chamber 40. This arrangement such that allof the liquid which passes from the casin to the pump must'first enter the upper en of the strainer and then emerge through the walls thereof,being thus freed 1 .thence,--together wich the .:liqu id,,through the ringAS;aeeries' of paral el wires 52 extends,
