ABSTRACT:
An anti-drip caulking device is provided having a "floating" anti-kickback dog which engages the plunger shaft. When the forward motion of the shaft is stopped, the floating action permits recoil of the plunger and dog until a tension spring is sufficiently stretched to balance the recoil force, or until a mechanical stop is engaged. The floating feature is provided by a tension and compression spring acting in opposition.
