(Cl. 259-41) This invention has reference to" nozzles for using pressure under liquids and has for its object to provide an improved nozzle for creating turbulence and directing jets underwater or other liquids, the nozzle itself being used for a variety of purposes, such as in washing machines According to this invention a nozzle comprises a trunk substantially of triangular shape in cross-section havinga slot along the apex and otherwise closed save for an inlet 'or'inlets for fluid under pressure, the side of'the triangle opposite the slot constituting the base-of the apparatus and the other two sides having plates mounted on them and spaced parallelfrom them, the spaces being substantially the same width as the slot along the apex of the trunk, these plates 7 2 The bottom edges of the .plates l do not descend as ,far as the base 4 of .the trunk, butterminate ,above this level and are flared or being separated above the slot in the apex of the trunk, by an opening substantially the same width as the slot below, the plates at their lower ends being turned outwardly, the construction providing that when fluid under pressure is forced into the trunk, the whole device being under liquid, the fluid escaping by the slots along the apex of the trunk will draw the surrounding liquid up the passages between the platesand' the trunk and will eject theliquid from the top. The invention is more particularly set forth with reference to the accompanying drawings, wherein r Fig. l is a brokenside elevation of a'nozzle according to the invention and Fig.2 is a cross-section; a As shown in the drawings the nozzle is made in the form of a-pipe or trunk 310i triangular I shape in cross section, the shape of thetriangle being preferably isosceles, though this is not necessary, butwhen it is isosceles as shown, theshortest face 4 constitutes the base, At the apex of the triangle there is a slot 5 from end to end i and the distance between the sides of the trunk 3 and these plates I0 is the same distance asthe width of the slot 3 along the apex of the trunk. The plates are carried up beyond the apex of the trunk until their edges are separated by a space H which also is the same width as the slot 6 in the trunk.

flangedo'u'twardly as at I2 to form a guide orwider entrance to the passages between the trunk and the plates.

The base 4 and hence the whole apparatus, is supported on rockers or like supports, such as a ball l3 engaging a cavity in a plate It adjustable on 'a screw l5, which willhold the apparatus level, the screw ISacting as a levelling screw, but not rigidly, as the surge of the water in the tankacting on the outwardly turned flanges of the plates may cause, and in some instances it is desirable that itshould cause, the nozzle to rock.

If the apparatus is to be used in a dish-washing or like machine it is mounted in a desired part ofia tank, there may, of course, be several in one tank, and when the tank is filled with water the nozzle apparatus is immersed and the liquid under pressure is turned on, through the coupling and pipe 8 and lrespectively. This causes an outrush of the air, gas or steam used as the pressure medium, from the slot 5, in the apex of the trunk, and this draws water along the passages between the trunk 3 and the plates l0 and ejects it from the top slot H formed by the edges of the converging plates ID, the operation continuing as long as the pressure is kept up. In this manner a great turbulence is set up in the liquid in which the apparatus is immersed.

While the invention has been described with reference to apparatus having one inlet for fluid under pressure, it is to be understood that more than oneinlet may be, used as for instance an inlet at each end or at any other suitable position; or positions. a

What I claim as my invention and desire to secure by Letters Patent is: a

1. A vnozzle for using pressure under liquids, comprising'a body having a bottom wall, end walls and inclined sidewalls forming a trunk of triangular shape in cross-section, said trunk' having a slot along its apex and an inlet opening in one of its end walls, the trunk being otherwise closed, means for connecting a supply pipe with said inlet opening, plates secured onthe inclined side walls of said trunkin parallel spaced relation thereto, the space between said plates and side walls being theQsame as the width of the slot along the apex of the trunk, said plates having their converging upper ends spaced apart a distance corresponding to the width of said slot and having their lower ends turned outward from said trunk at some distance above the lower end or the trunk, and means for rockably sup- REFERENCES C T D wrung and WW the level of 584d M The following references are of record in the its associated plates. file of this patent:
