Abstract
A combination device including a layout tool having a rectangular plate and a rectangular endpiece; and a square adaptor having an attachment plate and a ruler assembly. The layout tool is provided with a number of slots and apertures which allow a construction worker to make quick, standard measurements. The square adaptor includes a pivotable ruler which can be aligned parallel to or perpendicular to the longitudinal edges of the layout tool.
Claims19
A construction layout tool comprising:
- (a) an elongated, rectangular plate having two opposing logitudinal edges, two opposing transverse edges, and two opposing planar surfaces, said rectangular plate having first indicia marking a centerline located equidistant between said longitudinal edges, and provided with a central slot through said plate and aligned with said first indicia;
- and
- (b) a rectangular endpiece attached to a first transverse edge of said plate, said endpiece and said plate being substantially at right angles to each other, where a first portion of said endpiece extends away from a first planar surface of said plate for approximately twice the thickness of a standard 2.times.4, and where a second portion of said endpiece extends away from a second planar surface of said plate for approximately the thickness of a standard 2.times.4;
- wherein said first portion of said endpiece is provided with a central aperture having an edge located half way between said first planar surface and the edge of said first portion most distal from said first planar surface.
A combination layout tool and square comprising:
- a layout tool including
- an elongated, rectangular plate having two opposing longitudinal edges, two opposing transverse edges, and two opposing planar surfaces;
- and
- a rectangular endpiece attached to a first transverse edge of said plate, said endpiece and said plate being substantially at right angles, where a first portion of said endpiece extends away from a first planar surface of said plate and a second portion of said endpiece extends away from a second planar surface of said plate;
- and
- a square adaptor including an attachment plate adapted to abut at least one of said two planar surfaces of said layout tool;
- and ruler means extending from an edge of said attachment plate.
A combination layout tool and square as recited in claim 13 wherein said attachment plate is T shaped having a flat portion adapted to abut at least one of said two planar surfaces and a pair of extensions along one edge for engaging an edge of said plate, said rule means extending from said edge having said pair of extensions.
A construction layout tool comprising:
- (a) an elongated, rectangular plate having two opposing longitudinal edges, two opposing transverse edges, and two opposing planar surfaces, the transverse width of said plate being substantially the transverse width of a standard 2.times.4, said plate being provided with centerline markings along a centerline approximately one half the way across said transverse width, an elongated, central slot aligned with said centerline, and an elongated first side slot and an elongated second side slot, said first side slot and said second side slog being symmetrically aligned on either side of said centerline;
- and
- (b) a rectangular endpiece attached to a first transverse edge of said plate, said endpiece and said plate being substantially normal, the transverse width of said rectangular endpiece being substantially the transverse width of a standard 2.times.4, said endpiece being provided with centerline markings along a centerline approximately one half the way across said transverse width, and where a first portion of said endpiece extends away from a first planar surface of said plate and a second portion of said endpiece extends away from a second planar surface of said plate, the length of said second portion being substantially the thickness of a standard 2.times.4 and the length of said first portion being substantially twice the length of said second portion.
