Patented Aug. 19, 1947 El N i T E D S T T AGITATOR NOZZLE Carl S. Brown, Lakewood, Ohio,

assignor to Glascote Products, Inc., Cleveland, Ohio, a corporation of Ohio Application September 14, 1944, Serial No. 554,094

1 Claim.

This invention relates to a nozzle and particularly to an agitator nozzle. More specifically, the invention is concerned with the provision of an agitator nozzle which may be projected into a tank or other container, secured to the walls thereof, and subsequently adjusted to direct the flow of liquid from the nozzle without requiring access to the interior of the container or removal of the nozzle from the walls thereof. These, therefore, are the general objects of the present invention.

A more specific object of the invention is to provide agitator nozzle which may be inserted through an opening in the outer or jacket wall of a jacketed container, secured in place as by welding, and thereafter adjusted to control the direction of the flow of fluid through the nozzle into the jacket space without requiring access to the space other than through the conduit leading to the nozzle.

Other objects and advantages of the invention will become more apparent from the following description, reference being bad to a preferred embodiment of the invention illustrated in the accompanying drawings. The essential and novel features of the invention will be summarized in the claim.

Referring now to the drawings, Fig. l is a fragmentary sectional view of a jacketed container having my improved nozzle as applied thereto; Fig. 2 is an elevation of the nozzle looking in the direction indicated by the lines 2-2 on Fig. 1; Figs. 3 and 4 are sectional views of the nozzle, the planes of the sections being indicated by the correspondingly numbered lines on Fig. 3; and Fig. 5 is a section illustrating a different manner of attaching the nozzle to the tank.

In the drawings, I have illustrated my nozzle as applied to a jacketed tank, the internal wall of which is illustrated at I5, the external or jacket wall at It. The jacket 36 is secured to the internal or tank wall by welds ll and provides an enclosed jacket space it. The wall lb of the jacket is provided with an opening l9 through which a nozzle body 20 extends having a fluid passageway 26 extending axially therethrough. This body 26 is provided with a flange 2! which may be secured to the wall of the jacket, as by welds 22, to thereby completely close the opening l9, and provide a fluid tight permanent joint between 2 jacket wall and the nozzle body. The inner portion of the nozzle body 2! is reduced in cross section and is provided adjacent its end with internal threads 25 arranged to receive the threaded end portion 3!! of a nozzle outlet 30.

The outlet 39 is provided with a fluid passageway 36 the inner portion of which forms a continuation of the body passageway 26, and the outer portion of which extends at right angles to the passageway 26 to divert fluid into the jacket space. The member 30 may be rotated about the axis of the body member '20, as indicated by the dotted line position 36A in Figs. 1 and 4, to control the direction of flow of fluid from the nozzle. The nozzle is particularly adapted for 'use in connection with jacketed containers in which fluid in the jacket space is utilized to cool or heat the contents of the container. In such installations it is often desirable to control the direction of flow of fluid in the jacket space dependent upon the nature of the change of heat desired between the contents of fluid in the jacket space. In the construction shown in Figs. 3 and l, the inner or threaded end 3| of a nozzle 30 is provided with slots 34 which may be engaged by a tool, projected through the longitudinal opening or passageway 26 in the body 20, to

facilitate rotating the nozzle to the desired position.

The external portion of the body 20 is threaded as at 21 to receive a coupling member, such as that indicated at H in Fig. 1, for connecting a conduit to with the nozzle.

In Fig. 5 is illustrated a diiierent mode of attachment of the nozzle to the tank. Here a coupling Gil is welded to the exterior of the tank jacket and is provided with tapered internal threads 64 to coact with external tapered threads 52 formed on the body member 26. The tapered threads provide a liquid tight joint between the body 28 and the tank and the slots 34 in the nozzie permit accurate positioning of the nozzle after such tight joint has been eiiected. A shield 10 may be secured to the internal wall of the jacket E6 to protect the tank wall from the effect of the jet and to prevent the nozzle from being inadvertently disconnected from the body 20.

From the foregoing description, it will be seen that I have provided a very simple and efficient nozzle member which may be secured in place in the walls of a receptacle with the nozzle member projecting inwardly of the wall, the position of the nozzle member being controlled from the exterior of the container through the medium of the fluid passageways through the nozzle.

I claim:

An agitator nozzle comprising a tubular body adapted and arranged to partially extend through an opening in the Wall of a container or the like,

a flange on said member for securement to such 10 Numb wall to close the opening therein and fasten the body thereon, said body having a fluid passageway extending therethrough to conduct fluid from one side of the wall to another, a nozzle member threadingly secured to said body member on one side of said wall, said nozzle being provided with slots accessible from the fluid passageway in said body for engagement by a tool passed through said passageway therein to thereby facilitate adjustment of the position of said nozzle.
