  • Patent number: 9707597
    Abstract: A re-conformable material removal system comprises a head or receiver portion having an inner chamber with a plurality of material removal members arranged in side-by-side relationship to one another. First, actuator ends are disposed in the inner chamber of the head or receiver portion and second, surface contact ends project outwardly to define a contact edge. A biasing member is disposed within the inner chamber of the head or receiver portion, between the material removal members and the top, to yieldably bias the material removal members in an extended position wherein placement of the re-conformable material removal system against a surface results in yielding of the biasing member and movement of the material removal members into the inner chamber when the surface is uneven thereby resulting a conformed contact edge that is continuously adjustable and conformable to the contour of the surface.

  • Patent number: 9630215
    Abstract: A re-conformable material removal system comprises a head comprising an axial slot extending from an inner chamber to the exterior thereof. A plurality of material removal blades are arranged in side-by-side relationship and have first, proximal ends disposed in the inner chamber, axially extending blade shafts extending through the axial slot and second, distal ends projecting outwardly from the housing to define a removal edge. A biasing member is disposed within the inner chamber to yieldably bias the blades to a fully extended position through the axial slot; wherein placement of the re-conformable material removal system against a surface results in yielding of the biasing member and movement of the blades into the housing when the surface is uneven, resulting in a conformed edge that is continuously adjustable and conformable to the contour of the surface.
