Patent ID: 8616795

Claim:
A tool for depositing material onto a three-dimensional surface, said tool comprising: a first tubular member adapted to be carried by a spindle of a machine operable to move said spindle over a three-dimensional surface, said first tubular member comprising a first guide surface and a second guide surface; a second tubular member comprising a first guide surface engaging said first tubular member second guide surface and comprising a second guide surface engaging said first tubular member first guide surface; a first resilient member disposed to urge said second tubular member in a first axial direction relative to said first tubular member; a material holder carried by said second tubular member and adapted to carry said material extending therefrom in said first axial direction; and a second resilient member disposed to urge said holder into engagement with said second tubular member; said first tubular member and said second tubular member cooperating with said first resilient member to resiliently urge said material holder in said first axial direction such that when said material holder is proximate said three-dimensional surface, said material holder adapted to resiliently urge said material extending therefrom against said three-dimensional surface to thereby deposit said material onto said three-dimensional surface.
