Abstract
Assembly and method for guiding a portable power saw to make straight cuts in a workpiece is disclosed in which a reference edge is formed on a guidepiece held by the assembly. The reference edge is preferably formed by guiding the saw along a predetermined cutting path defined by the assembly to trim the guidepiece. To make a straight cut in a workpiece, the assembly is placed thereon with the reference edge defined by the guidepiece aligned along the line the cut is to be made and the power saw is guided by means of the assembly along the predetermined cutting path defined thereby.
Claims13
A saw guide assembly, comprising:
- housing structure;
- means associated with said housing structure for guiding an associated power saw along said housing structure in a straight path with the saw blade of said power saw moving along a predetermined straight cutting path alongside said housing structure;
- a guidepiece having a longitudinal dimension for alignment along said straight cutting path, said guidepiece being made of a material cuttable by said power saw to define a reference edge;
- said housing structure having a slot for slidably receiving said guidepiece, with said guidepiece extending transversely from said housing structure;
- and
- means associated with said housing structure for holding said guidepiece in a fixed position on said housing structure with the longitudinal dimension of said guidepiece substantially aligned with said cutting path, said holding means being adjustable to selectively position said guidepiece across said cutting path whereby by making a cut along said cutting path with said power saw said guidepiece may be trimmed along its longitudinal dimension to define a reference edge aligned with said cutting path usable for positioning said saw guide assembly on a workpiece.

A saw guide assembly, comprising:
- housing structure having substantially flat parallel upper and lower surfaces and longitudinally extending side edges;
- means associated with said housing structure for guiding an associated power saw along said housing structure in a straight path with the saw blade of said power saw moving along a predetermined straight cutting path alongside said housing structure;
- a guidepiece having a longitudinal dimension, said guidepiece being made of a material cuttable by said power saw to define a reference edge;
- said housing structure defining a slot of predetermined depth for receiving said guidepiece, said slot being a planar cavity opening in one of the longitudinal side edges of said housing structure, said slot being defined substantially parallel to said upper and lower surfaces of said housing structure and having its depth dimension extending transversely across said housing structure;
- said guidepiece being a planar member dimensioned for positioning in said slot to extend transversely from said housing structure;
- and
- means associated with said housing structure including clamping means having corrugated clamping surfaces for holding said guidepiece in a fixed position on said housing structure with the longitudinal dimension of said guidepiece substantially aligned with said cutting path, said holding means being adjustable to selectively position said guidepiece across said cutting path whereby by making a cut along said cutting path with said power saw said guidepiece may be trimmed along its longitudinal dimension to define a reference edge aligned with said cutting path usable for positioning said saw guide assembly on a workpiece.

A saw guide assembly, comprising:
- means for repeatably guiding an associated power saw along a straight cutting path;
- a guidepiece having a longitudinal dimension for alignment along said straight cutting path;
- and
- means for holding said guidepiece in a fixed aligned position with said cutting path to define a reference edge aligned with said cutting path usable for positioning said saw guide assembly on a workpiece, said holding means being adjustable to selectively position said guidepiece across said cutting path whereby by making a cut along said cutting path with said power saw said guidepiece may be trimmed along its longitudinal dimension to define a reference edge aligned with said cutting path usable for positioning said saw guide assembly on a workpiece;
- said means for guiding an associated power saw being located on said means for holding said guidepiece and said guidepiece being free of said means for guiding an associated power saw.

- said guidepiece being a planar member dimensioned for positioning in said slot to extend transversely from said housing structure;
- and
- means associated with said housing structure for releasably holding said guidepiece in a fixed position on said housing structure with the longitudinal dimension of said guidepiece substantially aligned with said cutting path, said holding means being adjustable to selectively position said guidepiece across said cutting path whereby by making a cut along said cutting path with said power saw sais guidepiece may be trimmed along its longitudinal dimension to define a reference edge aligned with said cutting path usable for positioning said saw guide assembly on a workpiece.
