Abstract
The tool of the present invention includes a compliance guide having a cylindrical vertical bore extending therethrough. Slidably mounted within the bore is a tool holder which is free to slide vertically, but which is held against lateral movement within the bore. Attached to the tool holder is a tool having a dauber pad at its lower end. A nipple is threaded within a vertical bore in the tool holder and extends upwardly therefrom through an aperture in a closure plate which fits over the upper end of the vertical bore in the compliance guide. A nut is threaded over the nipple above the closure plate and a spring below the closure plate yieldably urges the nipple and the tool holder downwardly until the nut engages the closure plate. Fluid is introduced through the nipple and extends downwardly to the dauber pad which absorbs the liquid and applies it to the work surface. A check valve is mounted within the dauber pad to prevent the dauber pad from receiving fluid until the dauber pad engages the work surface.
