ABSTRACT:
An improved caulking gun providing greater trigger-leverage and more nearly parallel trigger swing through location of the trigger pivot above the plunger shaft, a provision also providing maximum wear-point-access and oiling reminder, and simplifying fabrication and assembly together with a free-insert drive-grip spring, a self-pivoting release grip retained together with the counter-spring on the plunger shaft; subassembly requires only three welds for part securance and final assembly securance requires only one rivet and one upset-attachment.
