Abstract
A dye applicator including a head with a cavity (reservoir) and a plurality of bristles in the form of pins each covered with a sponge sleeve extending into the cavity and moistened with a catalyzed dye in the cavity by capillary action. A handle is connected to the head and includes a first container for receiving a dye compound, a second container for receiving a catalyst compound, a pump for each container, and a mixing chamber with a threaded compartment connected to the head cavity on one end, connected to the first container on the other end, and connected to the second container by a manifold for distributing the catalyst throughout the threaded compartment of the mixing chamber. A solenoid is positioned to actuate both pumps to deliver the dye and the catalyst separately to the mixing chamber and to deliver the mixed catalyzed dye to the head cavity. A selector switch allows a task to be selected and a processor, responsive to the selector switch and having an output connected to the solenoid, is configured to control the number of solenoid cycles based on the position of the selector for precise application of the dye based on the task selected.
