Abstract

A method and apparatus for applying a fluid onto a number of surfaces. The apparatus comprises a structure, an applicator associated with the structure, a first control device associated with the structure, and a second control device associated with the structure. Applying a first force to the first control device causes the applicator to move relative to a center axis of the applicator. Applying a second force to the second control device causes the fluid to be delivered from a fluid dispensing system to the applicator.

First claim

What is claimed is:

1. A method for applying a fluid onto a number of surfaces, the method comprising:
moving an applicator associated with a structure over the number of surfaces, wherein moving the applicator comprises creating a reciprocating motion using an actuation device in response to a first force being applied to a first control device associated with the structure;
delivering the fluid to the applicator from a fluid dispensing system in response to a second force being applied to a second control device associated with the structure; and
applying the fluid onto the number of surfaces with a desired level of coverage using the applicator while the fluid is being delivered to the applicator and while the applicator is being moved.

2. The method of claim 1 , wherein creating the reciprocating motion comprises:
sending air into a pulse generator in response to the first force being applied to the first control device; and
sending a number of air pulses from the pulse generator into the actuation device to create the reciprocating motion.

3. The method of claim 2 , wherein sending the number of air pulses from the pulse generator into the actuation device to create the reciprocating motion comprises:
pressurizing a piston in the actuation device by an air pulse in the number of air pulses such that the piston moves in a first linear direction; and
moving the piston in a second linear direction opposite the first direction in response to depressurization of the piston.

4. The method of claim 1 , wherein moving the applicator further comprises:
converting the reciprocating motion into oscillating motion of the applicator.

5. The method of claim 4 , wherein converting the reciprocating motion into the oscillating motion of the applicator comprises:
pressurizing a piston in the actuation device by an air pulse in the number of air pulses such that the piston moves in a first linear direction; and
rotating the applicator in a first direction about a center axis through the applicator in response to the piston moving in the first linear direction.

6. The method of claim 5 , wherein converting the reciprocating motion into the oscillating motion of the applicator further comprises:
moving the piston in a second linear direction opposite the first direction in response to depressurization of the piston; and
rotating the applicator in a second direction about the center axis through the applicator in response to the piston moving in the second linear direction.

7. The method of claim 1 , wherein delivering the fluid to the applicator from the fluid dispensing system comprises:
allowing the fluid to flow from the fluid dispensing system in response to the second force being applied to the second control device.

8. The method of claim 7 , wherein delivering the fluid to the applicator from the fluid dispensing system comprises:
sending air into an actuation device in the fluid dispensing system in response to the second force being applied to the second control device, wherein the air causes a piston in the actuation device to move such that the fluid is allowed to flow from the fluid dispensing system to the applicator.

9. The method of claim 1 , wherein delivering the fluid to the applicator from the fluid dispensing system comprises:
increasing a level of the second force being applied to the second control device to increase a rate of flow of the fluid from the fluid dispensing system to the applicator.

10. A method for dispensing a fluid from an applicator, the method comprising:
moving the applicator over a number of surfaces, wherein moving the applicator comprises creating a reciprocating motion using an actuation device in response to a first force being applied to a first control device associated with a structure associated with the applicator;
delivering the fluid to the applicator from a fluid dispensing system in response to a second force being applied to a second control device associated with the structure; and
dispensing the fluid from the applicator onto the number of surfaces with a desired level of coverage while the fluid is being delivered to the applicator and while the applicator is being moved.

11. The method of claim 10 , wherein creating the reciprocating motion comprises:
sending air into a pulse generator in response to the first force being applied to the first control device; and
sending a number of air pulses from the pulse generator into the actuation device to create the reciprocating motion.

12. The method of claim 11 , wherein sending the number of air pulses from the pulse generator into the actuation device to create the reciprocating motion comprises:
pressurizing a piston in the actuation device by an air pulse in the number of air pulses such that the piston moves in a first linear direction; and
moving the piston in a second linear direction opposite the first direction in response to depressurization of the piston.

13. The method of claim 10 , wherein moving the applicator further comprises:
converting the reciprocating motion into oscillating motion of the applicator.

14. The method of claim 13 , wherein converting the reciprocating motion into the oscillating motion of the applicator comprises:
pressurizing a piston in the actuation device by an air pulse in the number of air pulses such that the piston moves in a first linear direction; and
rotating the applicator in a first direction about a center axis through the applicator in response to the piston moving in the first linear direction.

15. The method of claim 14 , wherein converting the reciprocating motion into the oscillating motion of the applicator further comprises:
moving the piston in a second linear direction opposite the first direction in response to depressurization of the piston; and
rotating the applicator in a second direction about the center axis through the applicator in response to the piston moving in the second linear direction.

16. The method of claim 10 , wherein delivering the fluid to the applicator from the fluid dispensing system comprises:
allowing the fluid to flow from the fluid dispensing system in response to the second force being applied to the second control device.

17. The method of claim 16 , wherein delivering the fluid to the applicator from the fluid dispensing system comprises:
sending air into an actuation device in the fluid dispensing system in response to the second force being applied to the second control device, wherein the air causes a piston in the actuation device to move such that the fluid is allowed to flow from the fluid dispensing system to the applicator.

18. The method of claim 10 , wherein delivering the fluid to the applicator from the fluid dispensing system comprises:
increasing a level of the second force being applied to the second control device to increase a rate of flow of the fluid from the fluid dispensing system to the applicator.

19. The method of claim 3 , wherein movement of the piston in the first linear direction causes movement of the applicator in the first linear direction and wherein movement of the piston in the second linear direction causes movement of the applicator in the second linear direction.

20. The method of claim 12 , wherein movement of the piston in the first linear direction causes movement of the applicator in the first linear direction and wherein movement of the piston in the second linear direction causes movement of the applicator in the second linear direction.
