A central cylindrical bore directs the discharge of dry material while a plurality of pairs of spray nozzles, situated on two different circles around the bore, spray an adhesive or other liquid into the dry material stream. E'ach nozzle of a pair is located in diametric opposition to the other. The spray nozzles are slotted to produce fanshaped sprays, all slots being aligned parallel to a vertical line bisecting the gun. Although each pair of nozzles produces a line of spray intersection through the cylindrical stream of dry material, the intersection lines fall at different points along the length of the stream.

5 Claims, 4 Drawing Figures I SPRAY APPARATUS BACKGROUND OF THE INVENTION The invention relates to apparatus for applying a mixture of dry fibrous or particulate material and a liquid onto a surface, and more particularly to a spray gun or nozzle for this purpose. The apparatus of the invention is particularly useful for the mixing of a liquid adhesive with a dry cellulose insulation material during application to a substrate such as a wall, ceiling, beam, pipe, duct, etc.
Prior art spray guns intended for the purpose of this invention have employed a variety of designs for coating the dry particles with the liquid. A spray gun according to the present invention is generally of the type shown in US. Pat. No. 3,606,154 having a plurality of liquid spray nozzles surrounding a central dry material orifice for spray coating the dry material as it exits the orifice. However, a persistent problem with prior art spray guns has been the loss of dry material during spraying. Dry material not adequately coated or impregnated with adhesive will fall from the work surface and be wasted. As discussed in the above-mentioned patent, some prior systems have involved a drop off rate of up to 50 percent. The apparatus according to the above-mentioned patent employs a plurality of flat, fanshaped liquid sprays slicing into an oval shaped dry material stream, reportedly resulting in a drop off rate of less than percent. The four liquid jets of the patented gun are located around the oval shaped dry material orifice, two slightly offset from its major axis and two from its minor axis. The slots in the jets are all arranged parallel to the major axis of the oval orifice. Although the two converging fan streams from the jets on the minor axis intersect somewhere in the dry material stream the two major axis jets are offset and their converging streams are stated not to intersect for better wetting of the dry particulate material.
SUMMARY OF THE INVENTION The present invention provides an improved spray gun for mixing a liquid with a dry material during application. The design of this invention facilitates intermingling of liquid adhesive with dry cellulose insulation material such that the gun is capable of operating at a drop off rate below 5 percent and usually 2 percent or below. This results in a substantial reduction in both dry material and adhesive used on a job, with corresponding economic savings. Instead of an oval shaped dry material orifice, the spray gun of the present invention utilizes a circular orifice. Around this dry material orifice are spaced at least two pairs of slotted liquid jets, all of the slots of which are parallel to a vertical line through the face of the dry orifice.
The fan-shaped liquid streams all converge on the dry stream. However, at least one pair of streams lie in a single plane, their centerlines intersecting at a first point in the dry stream. A pair of fan streams from another pair of jets lie in two converging planes, their stream centerlines intersecting at a second point in the dry stream non-coincident with the first.
It is not clearly understood why this particular spray gun design with its cylindrical dry orifice and specific jet arrangement, more particularly described in the following description, results in a more efficient operation. The design was determined through experimentation and it has been found that the present apparatus produces a superior wetting of the dry material and a minimal drop off rate.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side elevational view of a spray apparatus according to the present invention, indicating spray patterns;
FIG. 2 is a front elevational view of the spray gun;
FIG. 3 is a sectional view of the spray gun taken along the line 33 of FIG. 2; and
FIG. 4 is a diagrammatic plan view of the spray gun and spray patterns indicating points of spray intersection of the diametrically opposed slotted nozzles.
DESCRIPTION OF A PREFERRED EMBODIMENT Referring to FIG. 1, spray apparatus according to the invention is generally indicated by the reference number 10. The spray gun 10 includes a handle 11 and a body 12 having a face section 13 and a cylindrical bore 14. The bore 14 has a frontal orifice 16 for discharge of dry fibrous or particulate material 17 and a rear fitting 18 for attachment to a dry material supply 19. The gun 10 is commonly used at a distance of 4 to 6 feet from a substrate (not shown).
Connected to the face section 13 is a valved liquid supply fitting 20 which receives a liquid supply line 21. The pressurized liquid, which is an adhesive when the gun 10 is used to apply insulation material, is conducted through the face section 13 to a plurality of liquid spray jets 22 and 23 which are mounted preferably by threaded connections in boss areas 24 and 26 of the face section 13.
Turning to FIG. 3, the face section 13 of the body 12 is shown in section. Channels 27 through the face section 13 conduct the pressurized liquid to the spray nozzles 22 and 23.
As best seen in FIG. 2, the liquid spray jets 22 and 23 are spaced peripherally around the central dry material orifice l6. .lets marketed by Spraying Systems Co. of Bellwood, Ill., designated No. 40015, have been determined very satisfactory for this use. Best results have been obtained with liquid adhesives under a pressure of from about to 225 pounds per square inch. The gun 10 operates very efficiently with only four jets, two 22 lying in diametric opposition on a first line 28 bisecting the orifice l6 and two 23 in diametric opposition on a second line 29, normal to the first, bisecting the orifice 16. Slots 30 of the slotted jets 22 and 23 are all arranged parallel to the first line 28. In this preferred embodiment, the spacing of the jets 22 from the orifice 16 is greater than that of the jets 23. Although the handle 11 of the gun 10 is shown on the line 28, it may extend in any direction from the body 12 of the gun 10.
As indicated in FIGS. 1, 2. 3. and 4, the liquid spray nozzles 22 and 23 all converge toward an axis 31 of the dry material bore 14 and orifice 16. The bosses 24 and 26 provided on the face section 13 are angled as necessary. Optimum results have been obtained with the angles A, defining the direction of jets 22, being from about 30 to 35 (preferably about 34) and the angles B, defining the direction of jets 23, being from about 8 to 12 (preferably about l0).'The jet slots 30 of the jets 22 are each spaced from about 1 A to l A inch (preferably about I /2 inch) from the axis 31 of the orifice l6 and the slots 30 of the jets 23 are each spaced from about to l V2 inch (preferably about 1 inch) from the axis 31. The orifice 16 preferably has a diameter of from about 1 to l k inch, but this dimension appears to be less critical.
FIGS. 1 and 4 illustrate the intersections of the fanshaped sprays from the jets 22 and 23 and their relationship to one another and to the dry material stream 17. FIG. 1 shows fan-shaped sprays 32 from jets 22 and fan-shaped sprays 33 from jets 23 in side view. Their centerlines are referenced 32c and 33c respectively. FIG. 4 shows the spray centerlines 32c and 33c in plan view, where the sprays 32 and 33 would appear narrow, almost as lines.
An intersection point 34 of the centerlines 32c falls in the dry material stream 17 approximately on the axis 31 of the orifice 16. An intersection area 36 of the fan streams 32 is shown in FIG. 1.
The two fan streams 33 intersect in a line 37 passing through the dry stream 17. A point 38 on the line 37 represents the intersection of the stream centerlines 33c as illustrated in FIGS. 1 and 4.
If the slots 30 of the jets 22 and 23 lie approximately flush with the orifice 16, then the jets 22 arranged according to the angles and dimensions discussed above would produce a stream intersection point 34 and area 36 in the neighborhood of 2 54 inch out from the orifice 16. The jets 23 if so arranged would produce a more remote intersection line 37 and point 38 around i inch from the orifice 16. Thus both pairs of liquid fan streams 32 and 33 slice into the cylindrical dry material stream 17 but at different angles and with different points of intersection.
The above described preferred embodiment provides a spray mixing apparatus capable of applying an almost saturated mixture to a surface. When used with dry fibrous or particulate cellulose insulation material and liquid adhesive, the apparatus yields an almost ideal mixture which adheres to all common substrates and to itself with negligible waste of dry insulation material. Coatings of up to 1.25 inches in a single application are common with the spray apparatus of the invention. Various other embodiments and alterations of the preferred embodiment, such as the provision of additional liquid spray nozzles or slight alteration in nozzle arrangement, will be apparent to those skilled in the art and may be made without departing from the spirit and scope of the following claims.
