Abstract
An articulated driving mechanism for a dispenser which in one embodiment is a caulking gun has a series of rigid links that are secured to one another by pins. The pins can slide in a slot which allows the links to space away from one another in a first position or be squeezed side by side which then prevents any rotation in a second position. The links all have ratchet teeth to engage two different driving wheels. The two driving wheels rotate at different speeds which allows the links to be consistently opened before reaching a circumferential wheel so that then the spaced links can rotate and safely and reliably rotate as they follow the circumference of the wheel. The articulated driving mechanism is used as a substitute for a push rod in a caulking gun in at least one embodiment.
