Abstract

Control method and apparatus for a manual spray gun may include a second manually actuated trigger disposed on the spray gun handle, with the second trigger being operational to select one or more coating operation parameters.

First claim

The invention claimed is:

1. A method for controlling the coating operation of a spray gun, comprising:
manually holding a handle of said spray gun during the coating operation,
manually actuating a trigger mounted on said handle to produce a signal that controls the starting and stopping of the flow of coating material from said spray gun, and
manually actuating a second trigger mounted on said handle to produce a signal that changes the value of a coating operation parameter,
wherein said second trigger is biased to a neutral position, between a first actuated position and a second actuated position, and wherein during said step of manually actuating said second trigger, said second trigger can be moved to said first actuated position to increase the value of said coating operation parameter and can be moved to said second actuated position to decrease the value of said coating parameter.

2. The method of claim 1 wherein during said step of manually actuating said second trigger, said second trigger can be moved to said first actuated position to increase the flow of coating material through said spray gun and can be moved to said second actuated position to decrease the flow of coating material through said spray gun.

3. A method for controlling the coating operation of a spray gun, comprising:
manually holding a handle of said spray gun during the coating operation,
manually actuating a trigger mounted on said handle to produce a signal that controls the starting and stopping of the flow of coating material from said spray gun, and
manually actuating a second trigger mounted on said handle to produce a signal that selects at least one coating operation parameter value,
said second trigger has a neutral position, a first actuated position and a second actuated position, and further including the step of displaying two or more sets of coating parameter values, and wherein during said step of actuating said second trigger, said second trigger can be moved to said first actuated position to scroll in a first direction through said displayed sets of coating material parameter values, and can be moved to said second actuated position to scroll in a second direction, which is opposite to said first direction, through said displayed sets of coating material parameter values,
wherein said second tripper is biased to the neutral position located between the first and second actuated positions.
