A self-loading paint applicator gun for painting the edges between walls and ceilings comprising, in combination:
- a stock further comprising:
- a rigid and generally tubular stock housing having a threaded base end, a threaded tip end, an elongated and generally tubular cartridge cavity extended from the base end to the tip end, and a linkage cavity extended below the cartridge cavity;
- a trigger pivotally coupled to the stock housing near the base end, extended through the linkage cavity, and terminated at a location exterior to the stock housing;
- a hand grip extended from the stock housing between the trigger and the base end;
- a funnel-shaped cartridge receiver having a radially extended portion disposed in the cartridge cavity and a radially retracted portion disposed in the linkage cavity;
- a generally elongated and tubular paint cartridge disposed in the cartridge cavity, the paint cartridge having a hollow and conical tip extended from one end into the cartridge receiver, a seat slidably disposed therein at the other end, and paint disposed therein between the seat and tip with the paint adapted to exit the cartridge from the tip end when a plunging force is applied to the seat;
- an elongated valve assembly disposed in the linkage cavity, the valve assembly having a base end and a tip end with the base end coupled to the radially retracted end of the cartridge receiver, the valve assembly further having an opened orientation for allowing the flow of paint through the cartridge receiver and a closed orientation for preventing the flow of paint through the cartridge receiver;
- and
- a trigger linkage extended within the linkage cavity between the trigger and the valve assembly with the trigger linkage having one position for placing the valve assembly in the opened orientation when the trigger is depressed towards the hand grip and another position for placing the valve assembly in the closed orientation when the trigger is released;
- a butt further comprising:
- an elongated and generally tubular butt housing having a threaded base end, a threaded tip end coupled about the base end of the stock housing, and a generally tubular plunger cavity extended from the base end to the tip end;
- a plunger having a plunging head on one end, handle on the other end, and a plunging rod therebetween with the handle extended from the base end of the butt housing for applying a plunging force and the plunging head disposed within the plunger cavity for delivering the plunging force to the seat of the paint cartridge;
- an end cap threadably coupled to the base end of the butt housing and extended about the plunging rod for preventing the removal of the plunger from the plunger cavity;
- and
- a spring disposed within the plunger cavity between the plunging head of the plunger and end cap for urging the plunger towards the seat of the paint cartridge;
- a barrel assembly further comprising:
- a first barrel having a threaded base end and a threaded tip end with the base end threadably coupled to the tip end of the stock;
- a second barrel having a base end and a slotted tip end with the base end telescopically received in the tip end of the first barrel;
- a barrel adjustment nut threadably coupled to the tip end of the first barrel and disposed about the base end of the second barrel to secure the second barrel in a fixed position against the first barrel when tightened;
- a flexible transfer hose having a base end coupled to the tip end of the valve assembly, an intermediate portion extended within the first barrel and the second barrel, and a tip end extended from the tip end of the second barrel;
- a protective sheath disposed about the transfer hose with the sheath having bellows formed thereon for preventing the transfer hose from being kinked and damaged when the second barrel is extended away from the first barrel and retracted towards the first barrel;
- and
- a elongated barrel handle having a first end coupled to the first barrel and a second end with a grip formed thereon;
- and
- a brush further comprising:
- a hollow sash having a beveled nozzle extended therefrom and coupled to the tip end of the transfer hose and a plurality of supply tubes extended therefrom in a direction remote from the nozzle;
- a plurality of bristles extended from the sash, disposed around the supply tubes;
- coupling means for pivotally coupling the sash to the tip end of the second barrel;
- whereby when a plunging force is applied to the plunger, paint from the paint cartridge flows through the cartridge receiver, valve assembly, transfer hose, and sash to wet the bristles for painting.
