Powered feed system for use with a machine saw table for providing guided motion along at least one axis
First Claim
1. A system for advancing a workpiece in guided fashion towards a rotating blade associated with a saw table, a fence securing to the table a distance from the blade, said system comprising:
- a housing secured upon the table such that the saw is disposed between said housing and fence, a width dimension associated with the workpiece generally corresponding to a distance between said housing and fence; and
a plurality of unidirectional rollers incorporated into said housing, each of said rollers exhibiting a vertical axis of rotation and having outer radial edges contacting associated side edges of the workpiece;
said unidirectional rollers facilitating linear feed of the workpiece against the blade, said housing and fence preventing kick-back of the workpiece resulting from a ripping operation performed by the blade.

Abstract
A system for advancing a workpiece in guided fashion towards a rotating blade associated with a saw or router table, the table including a fence securing a distance from the blade. A three-dimensional and elongated housing is secured upon the table, the saw being disposed between the housing and fence. The unit is laterally adjustable upon the table in directions towards and away from the blade, a width dimension associated with the workpiece generally corresponding to a distance between the housing and fence. A plurality of unidirectional rollers are incorporated into the housing, each of the rollers securing at linearly spaced intervals along the housing and each exhibiting a shaft supported and vertical axis of rotation, such that an outer radial edge associated with each roller contacts an associated side edge of the workpiece. The unidirectional rollers facilitate linear feed of the workpiece against the blade, the housing and fence preventing kick-back of the workpiece resulting from a ripping operation performed by the blade.

15. A system for advancing a workpiece in guided fashion towards a rotating blade associated with a saw table, a fence securing to the table a distance from the blade, said system comprising:
-
a housing secured upon the table such that the saw is disposed between said housing and fence, said housing having a specified shape and size and comprising an elongated three-dimensional unit laterally adjustable upon the table in directions towards and away from the blade, a width dimension associated with the workpiece generally corresponding to a distance between said housing and fence; and
a plurality of unidirectional rollers incorporated into said housing, each of said rollers securing at linearly spaced intervals along said housing and each exhibiting a shaft supported and vertical axis of rotation such that an outer radial edge associated with each roller contacts an associated side edge of the workpiece;
said unidirectional rollers facilitating linear feed of the workpiece against the blade, said housing and fence preventing kick-back of the workpiece resulting from a ripping operation performed by the blade. - View Dependent Claims (16, 17, 18, 19, 20)
