Abstract
A tool for laying out framing members includes a body comprising a blade and a tongue, the tongue oriented at a right angle to the blade in a common plane, wherein each of the blade and the tongue include indicia marking linear scales. Other indicia on the blade and tongue include information useful for building structures, such as roof structures. For example, indicia can include improved tables of data for marking and cutting rafters of various slope. Other indicia along the blade or the tongue indicate the length of the common rafter per foot of run as function of the slope.
Claims20
A tool for laying out framing members, comprising:
- a body comprising a blade and a tongue, the tongue oriented at a right angle to the blade in a common plane, wherein each of the blade and the tongue comprise indicia marking a linear scale adjacent to at least one edge thereof;
- indicia on a first surface of the body, the indicia comprising a first columnar table of values including each of:
- a length of a common rafter per foot of run as a function of a slope;
- a length of a hip rafter or valley rafter per foot of run as a function of the slope;
- a required width of the hip rafter or valley rafter as a function of the slope;
- a length of a common rafter per inch of run as a function of a slope;
- and
- a length of a hip rafter or valley rafter per inch of run as a function of the slope;
- indicia on a second surface of the body, the indicia comprising a second columnar table of values including each of:
- a length corresponding to a tangent of an angle of a purlin housing in the hip rafter or valley rafter as a function of the slope;
- a length corresponding to a tangent of an angle of a hip housing in a common rafter as a function of the slope;
- a first blade angle for cutting a fascia as a function of the slope;
- a second blade angle for cutting sheathing as a function of the slope;
- and
- a third blade angle for cutting the hip rafter or valley rafter as a function of the slope;
- and
- indicia along at least one edge of the body indicating the length of the common rafter per foot of run as function of the slope.
A tool for laying out framing members, comprising:
- a body comprising a blade and a tongue, the tongue oriented at a right angle to the blade in a common plane, wherein each of the blade and the tongue comprise indicia marking a linear scale adjacent to at least one edge thereof;
- and
- indicia adjacent to a surface of the body, the indicia comprising a columnar table of values including at least one value selected from the group consisting of:
- a length of a common rafter per inch of run as a function of a slope;
- and
- a length of a hip rafter or valley rafter per inch of run as a function of the slope;
- a required width of the hip rafter or valley rafter as a function of the slope;
- a length corresponding to a tangent of an angle of a purlin housing in the hip rafter or valley rafter as a function of the slope;
- a length corresponding to a tangent of an angle of a hip housing in a common rafter as a function of the slope;
- a first blade angle for cutting a fascia as a function of the slope;
- a second blade angle for cutting sheathing as a function of the slope;
- and
- a third blade angle for cutting the hip rafter or valley rafter as a function of the slope.
A tool for laying out framing members, comprising:
- a body comprising a blade and a tongue, the tongue oriented at a right angle to the blade in a common plane, wherein each of the blade and the tongue comprise indicia marking a linear scale adjacent to at least one edge thereof;
- and
- indicia along at least one edge of the body comprising a nonlinear scale indicating a length of a common rafter per foot of run as function of a slope.
