The uppermost end of the stem I6 extends outwardly through an opening in a cap 2| which is threadably engaged in the cylindrical body member l0 and which cap 2| defines, in combination with the interior of the cylindrical body member Ill, an annular chamber 22. A gasket 23 is positioned between the cap 2| and the uppermost portion of the cylindrical body member ID and a plurality of passageways 24 are formed in the body member I0 so as to establish communication between the annular chamber 22 therein and the chamber |2 therein. Each of the plurality of passageways 24 is L-shaped in that their lowermost portions run at right angles to the uppermost portions thereof and thereby provide a plurality of valve seats.

Valve members 25 are threadably engaged in the cylindrical body member ID so that pointed inner end portions thereof control the degree of opening through the passageways 24. Material to be applied by the nozzle is introduced into the annular chamber 22 by way of a tubular fitting 26, and a propellant medium such as compressed air is introduced into the nozzle and the chamber l2 thereof by way of a passageway 21 in the uppermost end of the stem l6. openings 28 provide communication between the passageway 21 in the stem 5 and the chamber I2.

The stem I6' is positioned in the cap 2| by means of an annular shoulder 29 thereon registering with the inner surface .of the cap 2| and a nut 30 is threadably engaged on the exterior portion of the stem l6 so that the stem is securely positioned with respect to the cap 2| and hence appropriately positioned centrally in the chambers II and I2.

It will thus be seen that when a coating material to be applied by the nozzle is supplied thereto by way of the tubular member 26 to the annular chamber 22 therein, the material will flow downwardly through the plurality of L-shaped passageways 24, past the controlling valves 25 and enter the chamber l2. The propelling medium such as compressed air enters the nozzle through the passageway 21 in the stem l6 and enters the chamber I2 by way of the openings 28.- The propelling medium so introduced picks up the material being handled by the nozzle and efficiently atomizes the same and directs it downwardly through the outwardly tapering chamber and with the circular baflle I3 directs the material outwardly in a 360 degree fan-like radius from the nozzle.

i The amount of coating material applied and the degree of atomization thereof is readily controlled by setting the individual valve members 25 (see Figures 2 and 6) which directly control the amount of material introduced into the atomizing zone of the nozzle which is the chamber |2 therein. The nozzle is therefore capable of handling many and various materials, 'as the amount of material'introduced into the mixing area thereof is individually controlled by the valve members 25 as well as by possible variations in the propelling air pressure.

The nozzle may be readily cleaned by disassembling the several parts and it will be seen that the nozzle comprises aminimum number of parts, each being of relatively simple and inexpensive construction and which parts will, in assembly, perform their intended purposeefilciently.

A plurality of Having thus described my invention, what I claim is:

l. A nozzle for applying coating materials to the interior of hollow objects, the said nozzle comprising a cylindrical body member having an outwardly tapering chamber formed in one end thereof, 'a cap for closing the other end thereof, the said cap having a depending annular flange formed thereon, the said annular flange threadably engaging the said body member and forming with the body member cooperatively, an annular chamber about the exterior of the depending flange of the cap and within the said body member, a plurality of passageways establishing communication between the said annular chamber and the interior of the body memher and individual valve elements disposed in the said passageways and operable exteriorally of the said body member, means for introducing material into the said annular chamber, an opening in the said cap, a stem positioned in said opening, a passageway for a propelling medium formed in said stem and forming means of'communication between the exterior of the said cap and the interior of the body member, the said stem extending through the hollow body member and a circular baffle positioned-on the saidstem and spaced with respect to the open end of the cylindrical body member.

2. A nozzle comprising a body member having an outwardly tapering chamber in one end thereof and a mixing chamberin the other end thereof, an annular shoulder in said body mem ber, a cap closing the end of the body member adjacent the mixing chamber, said cap having an annular depending flange threadably engaging the said annular shoulder and with the body member cooperatively forming an annular chamber, a plurality of passageways in said body member establishin communication between said annular chamber and said mixing chamber and individual valve elements in each of said passageways and operable exteriorly of the said body member, means for introducing material into the said annular chamber, an opening'insaid cap and a stem secured in said opening, a passageway in said stem establishing communication between the exterior of the said cap and the said mixing chamber, the said stem extending through the said body member and a disc secured to said stem exteriorly of the said body member and adjacent the tapering chamber therein.

3. A nozzle comprising a cylindrical body member having an outwardly tapering chamber in one end thereof and a cap on the other end thereof, a mixing chamber in the body member adjacent said cap, passageways through said body member for introducing material into the said mixing chamber, valves in said passageways and means for introducing a propelling medium into the mixing chamber, said propelling medium in one end thereof and a closure in the other end thereof, a centrally disposed elongated mixing chamber in the body member adjacent said closure, an annular depending flange on said closure forming an outer wall of said mixing chamber, an annular chamber in said body member on the other side of the said depending annular flange, passageways establishing communication between said annular chamber and said mixing chamber and positioned below said annular flange, a stem extending longitudinally through said body member and centrally of said depending flange and spaced with respect thereto, one end of the stem being hollow and openings in said hollow end communicating with said elongated mixing chamber near said closure, means for introducing material into the said annular chamber and a circular bafile secured to the other end of the said stem and spaced with respect to the body member to direct material from the tapering chamber thereof in a 360 degree pattern.

5. A nozzle comprising a cylindrical body member having an outwardly tapering chamber in one end thereof and a cap on the other end thereof, a stem positioned through said cap and extending through said cylindrical body member, an annular elongated mixing chamber in the cylindrical body member adjacent said cap and an annular depending wall on said cap spaced with respect to said stem and said cylindrical body member and forming a secondary annular chamber in said body member around the said annular elongated mixing chamber, a passageway in said stem communicating with said annular mixing chamber for the introduction of a propelling medium thereinto, a passageway in the side of said cylindrical body member establishing communication with said secondary annular chamber and forming means for introducing material into said secondary annular chamber and a secondary passageway in said cylindrical body member establishing communication between the saidsecondary annular chamber and said elongated mixing chamber and at a point therein spaced with respect to said annular depending wall and a conoidal baflie secured to the other end of said stem and spaced with respect to the body member for directing material from the tapering chamber in a 360 degree pattern.
