Abstract

The specification discloses a spray nozzle assembly for simultaneously spraying two materials, such as the material and catalist of urethane foam. The nozzle assembly is made up of two concentric spray nozzle members defining a central path and a cylindrical path concentric to the central path. The nozzles are so arranged that the material is given a turbulent motion as it emerges from the nozzle thereby causing a mixing of the two materials. The assembly can be used without a pump connected to a source of pressure.

SHEET 10F 3 JAMES R. #uuw R SIDNEY M. Fmca L MKM NOZZLE FOR SPRAYING FOAMING MATERIALS OBJECTS OF THE INVENTION It is an object of the invention to provide an improved nozzle arrangement.
Another object of the invention is to provide a mixing nozzle for urethane foam.
Another object of the invention is to provide an improved machine for applying urethane foam.
With the above and other objects in view, the present invention consists of the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims, it being understood that changes may be made in the form, size, proportions, and minor details of construction without departing from the spirit or sacrificing any of the advantages of the invention.
DESCRIPTION OF THE DRAWINGS FIG. 1 is a longitudinal cross sectional view of the nozzle according to the invention.
FIG. 2 is a longitudinal cross sectional view of another embodiment of the invention.
FIG. 3 is a side view of the primary stabilizer 1.
FIG. 4 is a front view of the primary stabilizer 1.
FIG. 5 is a front view of the secondary stabilizer housing 4.
DETAILED DESCRIPTION OF THE DRAWINGS Now with more particular reference to the drawings, the nozzle is made up of a primary stabilizing member which may be connected to a source of supply of a first material 18. The member 3 is externally threaded 20 and received on the internal threads 21 of the secondary stabilizing housing 4. The secondary stabilizing housing 4 has an external thread 22 which is received in the internal thread 23 on the secondary control housing 5. The secondary control housing 5 has an annular chamber 17 that connects to a source of supply at 16. The primary stabilizer support 2 is supported on a reduced size portion of the primary stabilizer 3 as shown. The primary stabilizer support 2 is a hollow cylindrical member having radially disposed openings 24 through which the material from the chamber 11 can travel into the chamber 12. The primary stabilizer 1 has tangentially disposed openings 14 that communicate from the annular space of chamber 12 to the central annular space 13 from whence the material can flow out the end of the secondary stabilizer housing 4. The secondary control housing 5 is hollow and its front internal surface engages the front end of the secondary stabilizer housing 4. The material may flow from the annular space 17 through the annular chamber and through the radially disposed openings 29 to space 28 and out through the end 30. Since the openings 14 and 29 are tangentially disposed relative to the central opening 13, the material passing from the chamber 12 to the chamber 13 is given a swirling action which it maintains as it passes from the exit end of chamber 13.
The second material passing from the supply source at 16 is passed through the chamber 15 and through the openings 29 to the space 28. This material, in passing through the openings 29 which is tangential to the space 28, is given a swirling action which it maintains as it passes from the exit end of space 2% and end Sb.
The pattern control orifice member 6 is held onto the secondary control housing 5 by means of a ring 7, thus the nozzle may be dismantled by removing the ring 7 thereby allowing the pattern control orifice member 6 to be removed and by removing the member 5 from the member 4 at external threads 22. Then member 4 can be removed from member 3 at external threads 20. This will allow the member 1 to be released as well as the primary stabilizer support 2.
' The embodiment of the invention shown in FIG. 2 is similar to that shown in FIG. 1; that is, the members are shown having added to the part numbers. The ring 107 in FIG. 2, however, holds the extension of 119 in place for extruding the material.
The foregoing specifications sets forth the invention in its preferred practical forms but the structure shown is capable of modification within a range of equivalents without departing from the invention which is to be understood is broadly novel as is commensurate with the appended claims.
