Abstract

A spray nozzle assembly includes a nozzle tip and a nozzle tip adapter. The nozzle tip adapter may include a visually perceptible indicia that corresponds uniquely to an offset angle value of the nozzle tip adapter. In one embodiment, the visually perceptible indicia may comprise a unique color for each offset angle among a selectable group of nozzle tip adapters. Another feature is a locator tool that includes an adjustable holder that is fixed in position relative to a spray nozzle tip or orifice during an alignment operation, and repositioned away from the nozzle tip during a spraying operation. The adjustable holder may include a measurement member to determine one or more distances between the nozzle tip or orifice and a location on a workpiece that will be coated or sprayed.

First claim

We claim:

1. A plurality of nozzle tip holders for a spray gun, the nozzle tip holders comprising:
a first nozzle tip holder comprising:
a first body that is adapted to be installed on a spray gun, said first body comprising a first bore that extends along a first axis from a gun end of said first body to a nozzle tip end of first said body,
said nozzle tip end of said first body defining a first recess configured to receive a nozzle tip, said first recess being in fluid communication with said first bore, and said first recess comprising a first seat surface,
said first seat surface being transverse a second axis, said second axis being formed at a first offset angle less than 90° from said first axis, and
said first body comprising a first color that uniquely corresponds to said first offset angle, and

a second nozzle tip holder comprising:
a second body that is adapted to be installed on the spray gun, said second body comprising a second bore that extends along a third axis from a gun end of said second body to a nozzle tip end of second said body,
said nozzle tip end of said second body defining a second recess configured to receive a nozzle tip, said second recess being in fluid communication with said second bore, and said second recess comprising a second seat surface,
said second seat surface being transverse a fourth axis, said fourth axis being formed at a second offset angle less than 90° from said third axis, the second offset angle being different from the first offset angle, and
said second body comprising a second color that uniquely corresponds to said second offset angle, the second color being different from the first color.

2. The plurality of nozzle tip holders of claim 1 , wherein:
the first offset angle is between 4° and 20°, and
the second offset angle is between 4° and 20°.

3. The plurality of nozzle tip holders of claim 1 , wherein:
the first offset angle is 6°, 8°, 10°, 12°, or 15°, and
the second offset angle is 6°, 8°, 10°, 12°, or 15°.

4. The plurality of nozzle tip holders of claim 1 , wherein:
said first color is on a first colored form on said first body,
said second color is on a second colored form on said second body, and
the second colored form being different from the first colored form.

5. The plurality of nozzle tip holders of claim 4 , wherein:
said first colored form is a line, dot, arrow, flange, geometric shape, or a surface of said first body, and
said second colored form is a line, dot, arrow, flange, geometric shape, or a surface of said second body.

6. The plurality of nozzle tip holders of claim 4 , wherein:
said first colored form comprises a first visually detectable mark that uniquely corresponds to said first offset angle,
said second colored form comprises a second visually detectable mark that uniquely corresponds to said second offset angle, and
said second visually detectable mark being different from said first visually detectable mark.

7. The plurality of nozzle tip holders of claim 1 , wherein the first body comprises at least one flat surface configured to engage a tool for tightening the first body to the spray gun.

8. The plurality of nozzle tip holders of claim 7 , wherein the first color is provided on the at least one flat surface of the first body.

9. The plurality of nozzle tip holders of claim 8 , wherein the at least one flat surface is configured to be parallel with a spray orifice of the nozzle tip when the nozzle tip is seated in the first recess.

10. The plurality of nozzle tip holders of claim 9 , wherein the at least one flat surface comprises two flat surfaces on opposite sides of the spray orifice of the nozzle tip.

11. The plurality of nozzle tip holders of claim 1 , wherein said first color and said second color are visible to a spray gun operator.

12. A spray nozzle assembly kit, comprising:
a first nozzle tip holder comprising:
a first body that is adapted to be installed on a spray gun, said first body comprising a first bore that extends along a first axis from a gun end of said first body to a nozzle tip end of first said body,
said nozzle tip end of said first body defining a first recess configured to receive a nozzle tip, said first recess being in fluid communication with said first bore, and said first recess comprising a first seat surface,
said first seat surface being transverse a second axis, said second axis being formed at a first offset angle less than 90° from said first axis, and
said first body comprising a first color that uniquely corresponds to said first offset angle;

a second nozzle tip holder comprising:
a second body that is adapted to be installed on the spray gun, said second body comprising a second bore that extends along a third axis from a gun end of said second body to a nozzle tip end of second said body,
said nozzle tip end of said second body defining a second recess configured to receive a nozzle tip, said second recess being in fluid communication with said second bore, and said second recess comprising a second seat surface,
said second seat surface being transverse a fourth axis, said fourth axis being formed at a second offset angle less than 90° from said third axis, the second offset angle being different from the first offset angle, and
said second body comprising a second color that uniquely corresponds to said second offset angle, the second color being different from the first color; and

a nozzle tip configured to be received in said first recess or said second recess, said nozzle tip comprising a flow passage that is in fluid communication with said first bore or said second bore, and said nozzle tip directing fluid flow in a direction along said second axis or said fourth axis when fluid is sprayed through said nozzle tip.

13. A spray gun kit, comprising:
a spray gun;
a first nozzle tip holder comprising:
a first body that is adapted to be installed on a spray gun, said first body comprising a first bore that extends along a first axis from a gun end of said first body to a nozzle tip end of first said body,
said nozzle tip end of said first body defining a first recess configured to receive a nozzle tip, said first recess being in fluid communication with said first bore, and said first recess comprising a first seat surface,
said first seat surface being transverse a second axis, said second axis being formed at a first offset angle less than 90° from said first axis, and
said first body comprising a first color that uniquely corresponds to said first offset angle;

a second nozzle tip holder comprising:
a second body that is adapted to be installed on the spray gun, said second body comprising a second bore that extends along a third axis from a gun end of said second body to a nozzle tip end of second said body,
said nozzle tip end of said second body defining a second recess configured to receive a nozzle tip, said second recess being in fluid communication with said second bore, and said second recess comprising a second seat surface,
said second seat surface being transverse a fourth axis, said fourth axis being formed at a second offset angle less than 90° from said third axis, the second offset angle being different from the first offset angle, and
said second body comprising a second color that uniquely corresponds to said second offset angle, the second color being different from the first color; and

a retainer configured to join said first nozzle tip holder or said first nozzle tip holder to said spray gun.

14. The spray gun kit of claim 13 , further comprising a nozzle tip configured to be disposed in said first recess or said
