Abstract
Abstract This invention relates to a deflector type spray nozzle for mounting on a pipe to obtain a flat trapezoidal shaped spray pattern. The spray nozzle is made entirely of a strong durable plastic resistant to corrosion and abrasion. It is equipped with a self-locating interchangeable bushing which may be easily changed to obtain different flow rates by means of a different size orifice and which fits in a simple straight hole in the pipe without auxiliary sealing means. A single size U-bolt and single size deflector assembly may be used for pipe sizes of 1 inch to 3 inches inclusive.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
140 words
In a fluid spray nozzle for mounting over a hole in the conduit, the combination comprising: a. a mounting member having an aperture, b. a curved deflector secured to said mounting member and having a flat wall portion adjacent said aperture, c. means providing a positioning surface on said mounting member at a predetermined distance from the flat wall portion of said deflector, d. an orifice bushing having a second positioning surface in engagement with the positioning surface of said mounting member and a bore with a wall portion disposed at said predetermined distance from said second positioning surface whereby fluid passing along the wall of said bore will flow smoothly onto the flat wall of said deflector, and e. fastening means for securing the mounting member and curved deflector with its assembled bushing over the hole in the conduit.
Claim 2
Dependent Claim
140 words
In a fluid spray nozzle for mounting over a hole in the conduit, the combination comprising: a. a mounting member having an aperture, b. a curved deflector secured to said mounting member and having a flat wall portion adjacent said aperture, c. means providing a positioning surface on said mounting member at a predetermined distance from the flat wall portion of said deflector, d. an orifice bushing having a second positioning surface in engagement with the positioning surface of said mounting member and a bore with a wall portion disposed at said predetermined distance from said second positioning surface whereby fluid passing along the wall of said bore will flow smoothly onto the flat wall of said deflector, and e. fastening means for securing the mounting member and curved deflector with its assembled bushing over the hole in the conduit.
Claim 3
Dependent Claim
39 words
A spray nozzle as in claim 1, wherein the orifice bushing has an aperture extending through its longitudinal axis so located on a transverse axis that the minimum wall thickness is maintained constant as the bushing aperture size increases.
Claim 4
Dependent Claim
39 words
A spray nozzle as in claim 2, wherein the orifice bushing has self-orienting means and the mounting member has mating orienting means in said aperture for the bushing so that it can only be assembled in the correct position.
Claim 5
Dependent Claim
53 words
A spray nozzle as in claim 3, wherein the orifice bushing has an external central flange section with a circular segment removed and the bottom end of the aperture in the mounting member has an enlarged mating pocket to receive the flanged portion of the bushing and to automatically orient the bushing properly.
Claim 6
Dependent Claim
40 words
A spray nozzle as in claim 4, wherein the chord remaining on the central flange section of the orifice bushing is perpendicular to a transverse centerline through the bushing aperture and adjacent to the minimum wall thickness of the bushing.
Claim 7
Dependent Claim
19 words
A spray nozzle as in claim 2 wherein the orifice bushing aperture is further defined as cylindrical in shape.
Claim 8
Dependent Claim
45 words
A spray nozzle as in claim 2, wherein the longitudinal aperture of the orifice bushing is so formed that the inner end is cylindrical and the outer end is a frustum of a cone having its larger diameter at the outer end of the bushing.
Claim 9
Dependent Claim
32 words
A spray nozzle as in claim 2, wherein the longitudinal aperture of the orifice bushing has a converging and then a diverging passageway of varying cross-sectional area in the direction of flow.
Claim 10
Dependent Claim
126 words
A fluid spray nozzle for mounting over an opening in a fluid discharge member comprising in combination: a. a mounting member having an aperture therein, b. a deflector secured to said mounting member in a position to overlap said aperture a predetermined amount, said deflector having a deflecTing surface extending from said mounting member, c. a replaceable bushing having a bore therethrough, said bushing insertable into said aperture and having a wall portion equal in thickness to the predetermined amount of said overlap to align the inner surface of the bore with the deflecting surface of said deflector plate, and d. means for securing said mounting member to said fluid discharge member with one end of said bushing in said opening of the fluid discharge member.
Claim 11
Dependent Claim
126 words
A fluid spray nozzle for mounting over an opening in a fluid discharge member comprising in combination: a. a mounting member having an aperture therein, b. a deflector secured to said mounting member in a position to overlap said aperture a predetermined amount, said deflector having a deflecTing surface extending from said mounting member, c. a replaceable bushing having a bore therethrough, said bushing insertable into said aperture and having a wall portion equal in thickness to the predetermined amount of said overlap to align the inner surface of the bore with the deflecting surface of said deflector plate, and d. means for securing said mounting member to said fluid discharge member with one end of said bushing in said opening of the fluid discharge member.
Claim 12
Dependent Claim
17 words
The fluid spray nozzle of claim 9, in which said bushing is made of a plastic material.
Claim 13
Dependent Claim
38 words
The fluid spray nozzle of claim 10 is which said fluid discharge member is a conduit and in which said securing means for said mounting member is a flexible U-shaped clamp having legs extending through the mounting member.
Claim 14
Dependent Claim
41 words
A spray nozzle as in claim 1, wherein the orifice bushing is made of a nonmetallic semirigid material so that the frustoconical end of the bushing will yield and conform to the hole in the conduit to effect the fluidtight seal.
Claim 15
Dependent Claim
66 words
A spray nozzle as in claim 1, wherein the fastening means comprises a generally U-shaped member, having threaded, extended legs and having an arcuate section connecting said legs which is thinner than the legs to encircle the conduit to conform readily to the size thereof, said legs extending through the mounting member, and a nut on each threaded leg to secure the assembly to the manifold.
