Adjustable caulk dispensing gun
First Claim
1. A caulk dispensing gun for dispensing a viscous material received in a cartridge, the cartridge including a piston slidably received therein for moving the viscous material out of the cartridge, said caulk dispensing gun comprising:
- a stock including a handle extended therefrom, and including at least one guide orifice formed therein, and including a frame for holding the cartridge therein,a piston rod slidably engaged through said at least one guide orifice of said stock, and including a first end having a plunger provided thereon for engaging with the piston of the cartridge,an actuating plate having an aperture formed therein for receiving said piston rod,a trigger pivotally secured to said stock and having an actuating pin for engaging with said actuating plate,means for biasing said actuating plate to engage with said actuating pin of said trigger, to allow said actuating plate to move said piston rod forwardly relative to said stock to force the viscous material out of the cartridge, andmeans for adjusting an inclination of said actuating plate relative to said piston rod, to adjust a frictional engagement between said actuating plate and said piston rod.

Abstract
A caulk dispensing gun for dispensing a viscous material received in a cartridge, includes a stock having a piston rod, an actuating plate having an aperture for receiving the piston rod, and a trigger pivotally secured to the stock and having an actuating pin for engaging with the actuating plate. The actuating plate may move the piston rod incrementally and forwardly relative to the stock to force the viscous material out of the cartridge. An adjusting device may adjust the inclination of the actuating plate relative to the piston rod, to adjust a frictional engagement between the actuating plate and the piston rod, particularly after the piston rod and the actuating plate have been worn out after use.
