Abstract

An improved miter table (20) for a circular saw table (10) having a rotating blade (12) includes an elongated guide plate (22) having a track (28) mountable to the saw table (10) and the miter table (20) includes an adjustable follower (30) for slidably engaging the track for longitudinal movement along the track (28) that provides transversely adjustable positioning of the miter table (20) with respect to the track (28) thereby to provide precise alignment of the workpiece with respect to the rotatable blade (12) during such movement.

Claims

1. In a circular saw table having a rotatable blade for cutting a workpiece and a miter table movable with respect to said circular saw table for guiding said workpiece with respect to said rotatable blade, the improvement in the miter table comprising:

an elongated guide plate having lateral edges mountable to said saw table;

said lateral edges defining two tracks extending generally parallel to the rotatable blade when the guide plate is mounted to said saw table;

said miter table including linearly oriented adjustable follower means for slidably engaging each said track for longitudinal movement therealong;

said follower means being adjustable transversely to said track to position said miter table transversely with respect to said guide plate, said follower means including a rotatable eccentric locator for locating said follower means on said miter table;

said eccentric locator being rotatable to effect positioning of said miter table with respect to said guide plate thereby to provide precise alignment of the workpiece with respect to the rotatable blade during such movement.

2. In a circular saw table having a rotatable blade for cutting a workpiece and a miter table movable with respect to said circular saw table for guiding said workpiece with respect to said rotatable blade, the improvement in the miter table comprising:

an elongated guide plate mountable to said saw table and having a track generally parallel to the rotatable blade when the guide plate is mounted to said saw table;

said miter table including an adjustable follower means for slidably engaging said track for longitudinal movement therealong and adjustable transversely to said track to position said miter table transversely, said follower means including a rotatable eccentric locator for locating said follower means on said miter table;

said eccentric locator being rotatable to effect positioning of said miter table with respect to said guide plate thereby to provide precise alignment of the workpiece with respect to the rotatable blade during such movement.

3. The improvement of claim 2 wherein said miter table further includes a miter fence and a polygonal-headed bolt for mounting said miter fence on said miter table, said miter table having a T-shaped slot extending through said miter table for restrainingly, slidably receiving the head of the bolt and having one end sufficiently large to receive said head into said slot when mounting the miter fence on said miter table;

said enlarged end including a ramp angled with respect to said slot for cammingly connecting said enlarged end to the slot receiving the head thereby to guide the head of the bolt into the slot by rotating the bolt sufficiently to align the polygon of the bolt head with the slot as the bolt is received thereby to allow the bolt to be easily positioned in said slot.

4. The improvement of claim 3 wherein said elongated guide plate includes two raised tracks on its lateral edges.

5. The improvement of claim 4 wherein said miter table includes a plurality of adjustable follower means mounted therebeneath for slidably engaging said tracks.

6. The improvement of claim 5 wherein each of said follower means includes an element having a straight edge for abuttingly slidably engaging said track and an aperture therein for receiving said eccentric locator.

7. The improvement of claim 6 wherein each locator is a bolt including a barrel portion having a non-collinear longitudinal axis relative to the bolt, said barrel portion being received therein said aperture in said element and said bolt being received in said miter table whereby rotation of said bolt alters the positioning of the follower and thereby the alignment of said miter table relative to said guide plate.

8. The improvement of claim 7 wherein said T-shaped slot is elongated and extends longitudinally along said miter table.
