Automatic drywall compound and drywall tape applicator

1 . An automatic drywall tape applicator, comprising:

a supply tube;

a solid supply tube centering guide engaged to said supply tube;

a vented supply tube centering guide engaged to said supply tube;

a compound control valve engaging said supply tube;

an actuator bracket, said actuator bracket disposed in communication with said supply tube;

at least one actuator, said at least one actuator disposed in communication with said actuator bracket;

a corner wheel pneumatic actuator in communication with said actuator bracket;

a pneumatic pressure regulator having inlet communication with said corner wheel pneumatic actuator;

a corner wheel linear actuator having inlet communication with said pneumatic pressure regulator; and

a linear actuator control strap assembly having mechanical engagement with a corner wheel linear actuator rod.

2 . The apparatus of claim 1 , further comprising: a linear actuator support bracket band, said linear actuator support bracket band externally engaged with a surface of said automatic drywall tape applicator; and

wherein said linear actuator support bracket band has a means of physical engagement with said corner wheel linear actuator.

3 . The apparatus of claim 1 , further comprising:

centering guides engaged centrally to the supply tube having a circumferential sealing relationship to the interior surface of a material reservoir sleeve of an automatic drywall tape applicator;

a compound control valve having an internal spring return mechanism;

an actuator support bracket being positioned in a perpendicular relationship to the longitudinal axis of said automatic drywall tape applicator;

wherein said corner wheel linear actuator having inlet communication with a pneumatic pressure source being in a normally open and retracted position when not acted upon;

a means of pneumatic activation whereby an actuator is engaged in a pulling fashion;

a means to reduce pneumatic contaminants from entering a pneumatic system comprising a check valve; and

a means to reduce detrimental chemical reactions between a drywall compound and a metallic surface comprising a barrier element.

4 . A method to provide a supplementary device for an automatic drywall tape applicator, comprising:

removing a cable and plunger assembly from an automatic drywall tape applicator;

removing a corner wheel finger trigger assembly ordinarily affixed to said automatic drywall tape applicator;

affixing the supplementary device to said automatic drywall tape applicator;

connecting a remote pumping source delivering drywall compound through a hose;

adjusting a pneumatic pressure regulator;

activating a compound control valve;

activating a corner wheel control valve;

rolling the automatic drywall tape applicator along a drywall joint applying tape;

deactivating a compound control valve;

activating a standard cutting mechanism of the automatic drywall tape applicator;

deactivating the corner wheel control valve; and

advancing a new length of tape per the standard use of the automatic drywall tape applicator.
