Patent ID: 8464858

Claim:
A scraper blade comprising: a) a tip having a front face with a scraper edge, an opposing supported end, a front side, and a back side; b) a resilient base attached to the tip, wherein the base has a supporting end, an anchor end, a front side, and a back side, wherein, in a relaxed state a reference line extends from the anchor end of the base to the scraper edge; c) wherein the base has a curved profile with a concave bend on the back side adjacent to the anchor end of the base; d) wherein in a first position, the scraper tip is rotated a predetermined amount relative to a fixed anchor end, such that the resilient base is deformed and the tip exerts a force in a first direction generally perpendicular to and outwardly from the front face; e) wherein in a second position, the scraper tip is compressed from the first position with a force applied to the tip in a direction generally parallel to the front face of the tip, such that the base deforms in a direction along the front face and also deforms in a direction perpendicular to and inwardly from the front face.
