Adjustable featherboard

For use with a table saw of the type which includes a substantially flat saw table having at least one groove formed in its surface and a blade slot extending through the table adjacent and parallel to said groove, a featherboard comprising:

• a body having a plurality of angularly extending elongated fingers;
• elongated means shaped to fit within a saw table groove;
• and
• bolt means for slidably attaching said elongate means to said body and expanding said elongate means transversely against side walls of a saw table groove to lock said elongate means thereagainst such that said body is selectively positionable relative to a saw table groove and
• releasably attachable by actuation of said attaching means.

In combination with a table for a table saw of the type having a blade slot and at least one groove adjacent said slot, a featherboard comprising:

• a body having a plurality of angularly extending elongate fingers;
• means engaging said groove;
• means slidably mounting said engaging means to said body and releasably securing said engaging means to said groove, including a pair of transverse slots formed in said body and a pair of mounting bolts, each positioned in a different one of said slots and having a threaded shank, a flared lower end extending below said body and attached to said groove engaging means, knob means threadedly engaging an upper end of said shank such that rotation of said knob means in a first direction causes said body to be clamped to said groove engaging means and said flared end to be drawn into said groove engaging means, thereby expanding said groove engaging means transversely sufficiently to lock it within said groove, and rotation of said knob means in an opposite direction unclamps said body from said groove engaging means and permits contraction of said groove engaging means such that said body is selectively positionable toward or away from said blade slot and said featherboard is selectively displaceable along said groove;
• and
• each of said slots has a width relative to a diameter of said shank sufficient to permit said body to be skewed relative to said saw opening.

For use with a table saw of the type including a substantially flat saw table having at least one groove formed in its surface and a blade slot adjacent and parallel to the groove, a featherboard comprising:

• a body having a plurality of angularly extending elongated fingers, a first transverse slot formed therethrough and a second transverse slot formed therethrough and parallel to said first slot;
• mounting bolt means including first and second threaded shanks extending through said first and second slots, respectively, and having flared lower ends, and means for threadedly engaging upper ends of said shanks;
• an expansion bar extending beneath said slot and sized to slidably engage a groove in a saw table and having first and second bores formed therethrough positioned to receive said first and second flared ends, respectively, whereby rotation of said engaging means clamps said body to said bar and draws said flared ends upwardly in said bore such that said bar expands transversely against side walls of a table groove to lock said bar thereagainst;
• and
• each of said slots has a width sufficient to form a gap about an associated one of said shanks to permit said body to be skewed relative to said expansion bar.

For use with a table saw of the type which includes a substantially flat saw table having at least one groove formed in its surface and a blade slot extending through the table adjacent and parallel to the groove, a featherboard comprising:

• a body having a plurality of angularly extending elongated fingers;
• means including an expansion bar sized to slidably engage a saw table groove and having a pair of bores therethrough;
• means for slidably mounting said bar to said body including a pair of transverse slots formed in said body and a pair of mounting bolts, each positioned within a different one of said slots and including a flared lower end positioned in different ones of said bores;
• each of said bores including a slit extending longitudinally of said bar, and said flared lower ends each include a pair of ears extending outwardly therefrom engaging an associated one of said slits, thereby preventing rotation of said shanks as said knob means are rotated;
• and
• said slots each having a width relative to a diameter of an associated one of said shanks sufficient to permit said body to be skewed relative to said expansion bar.
