The mounting adapter has a first element for removably attaching the adapter to the spider arm and a second element positioned circumferentially offset behind the first element for positioning the rotational or longitudinal axis of a surface processing tool circumferentially offset behind the trailing side of the spider arm. The first element is an elongate handle and the second element is a planar plate which extends generally perpendicularly from the handle between one end of the handle and a point intermediate the ends of the handle. ## Claims ### Claim 1 A mounting adapter for mounting a surface processing tool having a rotational or longitudinal axis to at least one spider arm of a motor driven rotatable spider assembly of a surface processing apparatus, said spider arm having a top surface and a bottom surface, and a leading side and a trailing side as a function of the direction of rotation of said spider assembly, said mounting adapter comprising: a first element for removably attaching said adapter to said spider arm and, a second element unitary with or connected to said first element and positioned circumferentially offset behind said first element, said second element comprising means for positioning the rotational axis of rotating surface processing tools or the longitudinal axis of non-rotatable surface processing tools circumferentially offset behind said trailing side of said spider arm. ### Claim 2 (depends on 1) A mounting adapter, as claimed in claim 1, wherein said first element attaches to the top surface of said spider arm. ### Claim 3 (depends on 1) A mounting adapter, as claimed in claim 1, wherein said first element attaches to the bottom surface of said spider arm. ### Claim 4 (depends on 1) A mounting adapter, as claimed in claim 1, wherein said first element comprises an elongate apertured bar and said second element comprises a tool support bar or plate extending generally perpendicularly from said bar between its ends and rigidly attached thereto. ### Claim 5 (depends on 1) A mounting adapter, as claimed in claim 1, wherein said means for positioning comprises at least one aperture in said second element. ### Claim 6 A mounting adapter, as claimed in 1, wherein said first element comprises an elongate handle and said second element comprises a planar plate, wider than said handle, and extending generally perpendicularly from said handle between one end of said handle and a point intermediate the ends of said handle, said planar plate comprising means for positioning the rotational axis of rotating surface processing tools or the longitudinal axis of non-rotatable surface processing tools circumferentially offset behind said trailing side of said spider arm. ### Claim 7 (depends on 6) A mounting adapter, as claimed in claim 6, wherein said planar plate is welded to said surface processing tool. ### Claim 8 (depends on 6) A mounting adapter, as claimed in claim 6, wherein said first and second elements are unitary. ### Claim 9 (depends on 6) A mounting adapter, as claimed in claim 6, wherein said planar plate includes at least one aperture therein for mounting a surface processing tool thereto. ### Claim 10 (depends on 9) A mounting adapter, as claimed in claim 9, wherein said surface processing tool is a rotatable tool having a bearing supported thereon and an elongate shank means extending through a central aperture of said rotatable tool and through a central bore in said bearing, one end of said shank means protruding through said aperture in said second element and being removably retained in said aperture. ### Claim 11 A method for mounting a surface processing tool having a rotational or longitudinal axis to at least one spider arm of a motor driven rotatable spider assembly of a surface processing apparatus, said spider arm having a top surface and a bottom surface, and a leading side and a trailing side as a function of the direction of rotation of said spider assembly, said method comprising: removably attaching a mounting adapter to said spider arm, said mounting adapter comprising a first element for attachment to said spider arm and a second element unitary with or connected to said first element and positioned circumferentially offset behind said first element; and attaching said surface processing tool to means on said second element for positioning the rotational axis of rotating surface processing tools or the longitudinal axis of non-rotatable surface processing tools circumferentially offset behind said trailing side of said spider arm. ### Claim 12 (depends on 11) A method, as claimed in claim 11, wherein said first element of said mounting adapter is attached to the top surface of said spider arm. ### Claim 13 (depends on 11) A method, as claimed in claim 11, wherein said first element of said mounting adapter is attached to the bottom surface of said spider arm. ### Claim 14 (depends on 11) A method, as claimed in claim 11, wherein said means for positioning comprises at least one aperture in said second element. ### Claim 15 (depends on 11) A method, as claimed in claim 11, wherein said first and second elements are unitary. ### Claim 16 (depends on 11) A method, as claimed in claim 11, wherein said first element comprises an elongate apertured bar and said second element comprises a tool support bar or plate extending generally perpendicularly from and rigidly attached to said apertured bar between its ends, and said method includes the step of attaching said surface processing tool to said support bar or plate. ### Claim 17 (depends on 11) A method, as claimed in claim 11, wherein said first element comprises an elongate handle and said second element comprises a planar plate, wider than said handle, and extending generally perpendicularly from said handle between one end of said handle and a point intermediate the ends of said handle, said planar plate comprising means for positioning the rotational axis of rotating surface processing tools or the longitudinal axis of non-rotatable surface processing tools circumferentially offset behind said trailing side of said spider arm, and said method includes the step of attaching said surface processing tool to said planar plate. ### Claim 18 (depends on 17) A method, as claimed in claim 17, where said planar plate is welded to said surface processing tool. ### Claim 19 (depends on 17) A method, as claimed in claim 17, wherein said planar plate includes at least one aperture therein and said method includes the step of mounting a surface processing tool within said aperture. ### Claim 20 (depends on 19) A method, as claimed in claim 19, wherein said surface processing tool is a rotatable tool having a bearing supported thereon and an elongate shank means extending through a central aperture of said rotatable tool and through a central bore in said bearing, said method including receiving one end of said shank means protruding through said aperture in said second element and removably retaining said shank means in said aperture.
