A system for applying a viscous mass upon a surface comprising a housing having a spout and a reservoir for carrying the viscous mass, an abutment spaced from the reservoir, and an impeller rotatably mounted proximate the reservoir having radially extending substantially flexible impeller elements for passing through and collecting the viscous mass upon rotation of the impeller, and for successively engaging the abutment past which the impeller elements are flexed, whereupon release therefrom impel mass particles through the spout against the surface, the abutment being selectively positionable for impelling the viscous mass in a predetermined trajectory.

[ Having fully described the invention in such clear and concise terms as to enable those skilled in the art to understand and practice the same, the invention claimed is:] [1.] An apparatus for applying a viscous mass to a surface, said apparatus comprising:a housing having a spout and a reservoir for carrying a viscous mass;an abutment spaced from said reservoir;an impeller mounted for rotation adjacent said reservoir and having radially extending substantially flexible impeller elements; anda wiper abutment having first and second ends mounted with said housing spaced from said abutment, said reservoir and said viscous mass, said wiper abutment adjustable between a first radial position relative said impeller and a second radial position relative said impeller;said substantially flexible impeller elements for passing through and collecting said viscous mass upon rotation of said impeller and for successively engaging said wiper abutment between said first and second ends at one of the first radial position and the second radial position past which said impeller elements are flexed, whereupon release therefrom impel mass particles for receipt into said reservoir to remove a first amount of viscous mass from said impeller elements in said first radial position of said wiper abutment and a second amount of viscous mass from said impeller elements in said second radial position of said wiper abutment, said first amount of viscous mass being different than said second amount of viscous mass, and then for successively engaging said abutment past which said impeller elements are flexed, whereupon release therefrom impel mass particles through said spout against said surface.
