Abstract
A workpiece-holding fixture for use with a table saw to cut straight, parallel or tapered sides on a workpiece. The fixture comprises a channel-shaped body having clamps for removably securing a workpiece in the body, a shield supported by the body for overlying the saw blade, and retainers cooperable with the table saw fence for preventing interference between the fixture and the saw blade. A guide is provided for use in supporting successive workpieces to enable them to be uniformly tapered.
Claims16
A fixture for holding and presenting an elongated workpiece to a cutting tool comprising:
- an elongated body having an upper flange, a lower flange parallel to and spaced from the upper flange, and a side wall interconnecting the upper and lower flanges in a manner to define an elongated, workpiece-receiving channel having an open side;
- a plurality of spaced apart clamping members carried by said upper flange for movements toward and away from the lower flange to clamp and unclamp the workpiece in said channel and for movements laterally of said upper flange;
- shield means carried by said upper flange and extending beyond said open side of said channel in a direction to overlie said cutting tool, said shield means having notches for the accommodation of portions of said clamping members;
- and retaining means carried by said body for limiting movement of said fixture in a direction toward said cutting tool, said retaining means having a first part extending transversely of said body in prolongation of said upper flange and a second part extending parallel to said side wall.
A fixture for holding and presenting an elongated workpiece to a cutting tool comprising:
- an elongated body having an upper flange, a lower flange parallel to and spaced from the upper flange, and a side wall interconnecting the upper and lower flanges in a manner to define an elongated, workpiece-receiving channel having an open side;
- a plurality of spaced apart clamping members carried by said upper flange for movements toward and away from the lower flange to clamp and unclamp the workpiece in said channel and for movements laterally of said upper flange;
- shield means carried by said upper flange and extending beyond said open side of said channel in a direction to overlie said cutting tool, said shield means having notches for the accommodation of portions of said clamping members;
- a guide bar accommodated in said channel, said guide bar being adjustable relative to said body to form a selected angle with said side wall;
- means for securing said guide bar at said selected angle;
- and means carried by said bar for engaging and positioning a workpiece in said channel.
A fixture for holding an elongated workpiece relative to a guide that is spaced from and in a selected plane relative to a cutting tool, comprising:
- an elongated C-shaped body having an upper flange, a lower flange underlying and spaced from the upper flange, and a side wall interconnecting the upper and lower flanges in a manner to define an elongated, workpiece-receiving channel, said side wall of said fixture being engageable with said guide;
- a plurality of workpiece clamping members on the upper flange for movements toward and away from the channel to clamp and unclamp the workpiece;
- a shield carried by said body and extending therefrom in a direction to overlie said cutting tool;
- and retaining means carried by said body and extending therefrom in the opposite direction to snugly but slideably accommodate said guide and retain said body spaced from said cutting tool.
A fixture for holding an elongated workpiece relative to a guide that is oriented in a selected plane relative to a saw blade, comprising:
- an elongated body having an upper flange, a lower flange underlying and spaced from the upper flange, and a side wall interconnecting the upper and lower flanges in a manner to define an elongated, workpiece-receiving channel, said side wall being engageable with said guide;
- a plurality of workpiece clamping members mounted on the upper flange for movement toward and away from the lower flange to clamp and unclamp a workpiece accommodated in said channel;
- a plurality of handles mounted on said upper flange for moving said body relative to said saw blade and saw guide while the side wall is engaged with the guide so as to move a workpiece clamped in the channel relative to said saw blade and provide a cut surface on said workpiece that is substantially parallel to said plane;
- a shield carried by said body and extending therefrom a distance and in a direction to overlie said cutting tool;
- and retaining means carried by said body and extending in the opposite direction to accommodate said guide and maintain said body against said guide and spaced from said cutting tool while said shield overlies said cutting tool.
