Abstract
A guide bar has a pair of clamps for mounting on the shoe of an electric power hand saw. The guide bar is adjustable both longitudinally and laterally in relation to the saw. This arrangement facilitates trimming strips off the ends or side edges of wood panels wherein the width of such strips may vary from a small fraction of an inch to several inches.
Claims5
In an electric power hand saw having a shoe to support the saw for movement on the face of a workpiece, a guide bar arranged for sliding engagement with an edge of the workpiece, means for mounting said guide bar on said shoe in different adjusted positions, said different adjusted positions being parallel with the blade of the saw within a small range determined by the width of said shoe for trimming a narrow strip off a straight edge of a workpiece such as a wood panel, said mounting means comprising a pair of clamps on said guide bar engagable with the opposite ends of said shoe, said clamps being slidable across said ends of said shoe and slidable lengthwise on said guide bar for adjusting the position of the guide bar laterally and longitudinally in relation to the saw, each of said clamps comprising an apertured lug having an ear overlying said shoe, said guide bar underlying said shoe and having a longitudinal slot to receive a bolt through the aperture in each lug, at least one of said lugs being elongated with said ear on one end thereof and only the other end thereof bearing against said guide bar, said bolt extending through an intermediate portion of said lug to apply leverage on the clamping base of said ear, and means on said lugs engaging said slot in said guide bar to prevent rotation of the lugs on said guide bar.
For use with an electric power hand saw having a shoe to support the saw for movement on a face of a workpiece, a guide bar to enable the saw to trim a narrow strip off a straight edge of a workpiece such as a wood panel, said guide bar being slidable on the under face of said shoe to a position very close to and parallel with the blade of said saw, and means for clamping said guide bar in adjusted positions against said under face of the shoe, said clamping means comprising a pair of clamps on said guide bar slidable along opposite ends of said shoe, said clamps engaging the top surface of said shoe, said guide bar comprising a channel member having its web portion slidable on said shoe, and a longitudinal slot in said web portion receiving bolts for said clamps.
For use with an electric power hand saw having a shoe to support the saw for movement on a face of a workpiece, a guide bar to enable the saw to trim a narrow strip off a straight edge of a workpiece such as a wood panel, said guide bar being slidable on the under face of said shoe to a position very close to and parallel with the blade of said saw with the ends of the guide bar projecting beyond the opposite ends of said shoe, longitudinal slots in said projecting ends of the guide bar, clamp bolts slidable in said slots, and a pair of clamps slidable across said ends of the shoe for clamping said guide bar in adjusted positions against said under face of the shoe, each of said clamps comprising an apertured lug receiving one of said bolts and having an ear overlying one of said ends of the shoe.
