Abstract
A carrier adapted to securely hold a workpiece for manual movement through cutting engagement such as with the saw blade of a band saw in a manner that allows for precise and predictable cutting of the workpiece into boards of desired thickness. The carrier is slidably positioned in the miter guide slot that extends in the saw work table parallel to the cut of the saw blade, and is adapted for manual positioning of the workpiece transversely with respect to the guide slot to adjust the depth of cut of the blade into the workpiece.
Claims1
A workpiece carrier for use with a power saw having (i) a flat work table provided with a guide slot, and (ii) a cutting tool extending above the work table for cutting a workpiece, the workpiece carrier comprising:
- (a) a horizontal base for supporting a workpiece, the base having a front, a back and opposite sides, and having a top and a bottom for sliding on the work table,
- (b) a guide bar secured to the bottom of the base for sliding positioning in the guide slot in the work table, the guide bar extending longitudinally toward said opposite sides and downwardly from the bottom of the base,
- (c) a slide member slidably engaging the base for lateral sliding movement relative to the base forwardly toward the front of the base and rearwardly toward the back of the base between a forward position and rear position,
- (d) a control arm extending longitudinally over the slide member and secured to the base on opposite sides of the slide member, the control arm being provided with a horizontal threaded through hole positioned above the slide member,
- (e) a longitudinally extending upright mounting plate positioned over the base and forwardly of the control arm, the mounting plate being secured to the slide member for sliding movement therewith on the base, the mounting plate having a front side and a back side, there being provided a plurality of horizontal clearance holes through the mounting plate between said front and back sides thereof,
- (f) a horizontal drive screw threaded through the threaded hole in the control arm and extending forwardly and rearwardly therefrom, the forward end of the drive screw rotatably connected to the mounting plate from the back side thereof, the drive screw being manually operable from a position behind the control arm for manually controlling the lateral sliding movement of the slide member and mounting plate together on the base upon turning the drive screw,
- (g) a plurality of threaded fasteners extending through the clearance holes in the mounting plate from the back side thereof the threaded fasteners being configured for threading directly into a workpiece located on the front side of the mounting plate, and
- (h) a pair of laterally spaced handles rigidly secured between the back side of the mounting plate and the back of the slide member for sliding movement therewith, the handles extending upwardly from the back of the slide member and forwardly over the control arm to the back side of the mounting plate.
