Abstract
A device for laying out an angle to form a borderpiece for a roof from a standard workpiece. The device includes first and second members, contact elements extending from each member. The contact elements contact opposing edges when the device is disposed on the workpiece. An edge of each first and second element defines the angle at which the workpiece is to be cut.

A device for laying out one of a first angle for a first roof pitch and a second angle for a second roof pitch on a generally planar surface of a standard workpiece with generally opposite first and second edges, each angle extending from the first edge of the workpiece such that the workpiece corresponds to a geometry for a borderpiece on a roof when the workpiece is cut along the angle, the device comprising:
- a substantially planar member defining a generally axial first slot and displaying upper and lower surfaces, first and second ends, and at least one continuous and linear scribing edge, the planar member including a first indicium on the upper surface proximate the first slot;
- a stationary first contacting member disposed proximate the planar member first and extending from the planar member lower surface;
- and
- a second contacting member with an aligning edge, the second contacting member including a contacting element, the contacting element slidably extending through the first slot and past the planar member lower surface,
- the second contacting member aligning edge aligning with the first indicium to define a distance between the first contacting member and the contacting element such that when the first contacting member and the contacting element contact respective workpiece first and second edges, the first angle for a given roof pitch is defined by the planar member scribing edge and one of the workpiece first and second edges.
A method of defining and forming a borderpiece from a standard workpiece with first and second generally opposite first and second edges using a device for laying out one of a first angle and a second angle on a generally planar surface of the workpiece, the device including:
- a substantially planar member defining a generally axial first slot and displaying upper and lower surfaces, first and second ends, and at least one continuous and linear scribing edge, the planar member including a first indicium on the upper surface proximate the first slot;
- a stationary first contacting member disposed proximate the planar member first and extending from the planar member lower surface;
- and
- a second contacting member with an aligning edge, the second contacting member including a contacting element, the contacting element slidably extending through the first slot and past the planar member lower surface,
- the second contacting member aligning edge aligning with the first indicium to define a distance between the first contacting member and the contacting element such that when the first contacting member and the contacting element contact respective workpiece first and second edges, the first angle for a given roof pitch is defined by the planar member scribing edge and one of the workpiece first and second edges, the method including:
- aligning the aligning edge and the first indicium;
- contacting the first contacting member and contacting element to respective workpiece first and second edges;
- and
- scribing a line along the scribing surface, thereby defining the first angle between the line and one of the workpiece first and second surfaces.
