Builder's measuring and marking tool

A builder's measuring and marking tool comprising:

• a planar member having a right triangle configuration, including a first side edge, a second side edge extending normal to said first side edge, and a third side edge intersecting said first and second side edges to form a hypotenuse of said right triangle configuration;
• an elongated aperture spaced apart inwardly from said third side edge and bounded by opposite straight edges parallel to said third side edge;
• a scribe bar spaced apart inwardly from said second side edge having at least one scribing edge parallel to said second side edge, said at least one scribing edge including at least one indentation at a predetermined distance from said first side edge corresponding to a standard width of a piece of timber;
• and
• an aperture in the form of a right triangle having a first inner side edge intersecting a second inner side edge at a right angle and a third inner side edge representing the hypotenuse of said right triangle aperture, said third inner side edge being parallel to said opposite straight edges of said elongated aperture.

A builder's measuring and marking tool comprising:

• a planar member having a right triangle configuration, including a first side edge, a second side edge extending normal to said first side edge, and a third side edge intersecting said first and second side edges to form a hypotenuse of said right triangle configuration, wherein the intersection of said first and second side edges defines a pivot point;
• abutment means along said first side edge for abutting against a work piece when said second side edge is positioned to extend over said work piece;
• distance marking indicia formed along said second side edge for marking a distance from said first side edge, including a predetermined distance corresponding to a standard width of a piece of timber;
• angle marking indicia formed along said third side edge for marking an angle and for marking a degree measurement for a common rafter plumb line;
• a scribe bar spaced apart inwardly from said second side edge having at least one scribing edge parallel to said second side edge, said at least one scribing edge including at least one indentation at said predetermined distance from said first side edge;
• an elongated aperture spaced apart inwardly from said third side edge and bounded by opposite straight edges parallel to said third side edge;
• common rafter marking indicia formed along a first straight edge of said elongated aperture for marking a unit rise measurement for a common rafter plumb line;
• first hip and valley marking indicia formed along a second straight edge of said elongated aperture for marking one of a unit rise and a degree measurement for a hip and valley rafter plumb line;
• an aperture in the form of a right triangle having a first inner side edge intersecting a second inner side edge at a right angle and a third inner side edge representing the hypotenuse of said right triangle aperture, said third inner side edge being parallel to said opposite straight edges of said elongated aperture;
• second hip and valley marking indicia formed along said third inner side edge for marking one of said unit rise and said degree measurement that is not marked using first hip and valley marking indicia;
• and
• linear marking indicia formed along said first inner side edge representing the distance from said second side edge.

A method of marking a seat cut on a work piece using a builder's measuring and marking tool comprising a planar member having a right triangle configuration, including a first side edge and a second side edge extending normal to said first side edge, abutment means along said first side edge, a distance marking indicia formed along said second side edge for marking a distance from said first side edge, including a predetermined distance corresponding to a standard width of a piece of timber, and a scribe bar spaced apart inwardly from said second side edge having at least one scribing edge parallel to said second side edge, said at least one scribing edge including at least one indentation located at said predetermined distance from said first side edge, said method comprising:

• drawing a plumb line on said work piece;
• placing said builder's measuring and marking tool on said work piece with said abutment means along a side edge of said work piece;
• sliding said builder's measuring and marking tool along said side edge of said work piece until said distance marking indicia for marking said predetermined distance overlays said plumb line;
• pivoting said builder's measuring and marking tool about a pivot defined by the intersection of said first and second side edges until said plumb line intersects said distance marking indicia for marking said predetermined distance and said at least one indentation of said scribe bar located at said predetermined distance from said first side edge;
• and
• marking a seat cut line along said second straight edge of the tool from said plumb line to said side edge of said work piece.
