Claim 8

The device of claim 6, wherein said hinge means includes an L-shaped upper piece, having a vertical leg affixed to said C-shaped bracket, a horizontal leg overlying a top face of the fence, a hinge connected to said horizontal leg remote from said vertical leg, a lower piece affixed to said U-shaped bracket and connected at said hinge to said upper piece whereby said hinge is on a side of the fence remote from the saw for clearance when said device is rotated into an inoperative position.

Claim 9

The device of claim 7, wherein a pair of hinge means, clamping means, and vertical elevating means are provided for stability.

Claim 10

The device of claim 8, wherein the saw is a rotary saw extending through a slit in the table in fixed relation thereto, the fence being provided parallel to and spaced from a face of the rotary saw.

Claim 11

A work guide attachment for placement on a fence of a table saw which has a circular saw extending through a slit in the saw table fixed for cutting in the slit, and the fence runs parallel to the circular saw, comprising in combination: hinge means connecting said attachment to an edge of the fence remote from the circular saw for rotating the attachment away from the saw to remove said attachment from the saw and a side of the fence and work area adjacent the saw, and means for altering the horizontal elevation of said attachment disposed between the fence and the saw when said attachment is rotated adjacent the saw so that said work guide attachment can be oriented to different horizontal elevations and therefor accomodate different size workpieces and templates associated with the workpieces, wherein said altering means comprises, a bracket attached to said hinge means, a threaded rod supported in said bracket, and a support bar fastened on said guide and threaded to said threaded rod, whereby rotation of said threaded rod vertically moves said support bar and therefore said guide from one horizontal elevation to another.

Claim 12

A work guide attachment for placement on a fence of a table saw which has a circular saw extending through a slit in the saw table fixed for cutting in the slit, and the fence runs parallel to the circular saw, comprising in combination: hinge means connecting said attachment to an edge of the fence remote from the circular saw for rotating the attachment away from the saw to remove said attachment from the saw and a side of the fence and work area adjacent the saw, and means for altering the horizontal elevation of said attachment disposed between the fence and the saw when said attachment is rotated adjacent the saw so that said work guide attachment can be oriented to different horizontal elevations and therefor accomodate different size workpieces and templates associated with the workpieces, wherein said altering means comprises, a bracket attached to said hinge means, a threaded rod supported in said bracket, and a support bar fastened on said guide and threaded to said threaded rod, whereby rotation of said threaded rod vertically moves said support bar and therefore said guide from one horizontal elevation to another.

Claim 13

A means having a saw fence and a saw for uniformly altering the distance between a table saw surface and an associated work guide comprising in combination: attachment means connecting said guide to the fence, vertical elevation means between said attachment means and said guide to elevate the guide from one horizontal elevation to anther relative to the table saw surface, and hinge means parallel to the cutting direction of the saw connecting said elevation means to said attachment means to move said guide from an operative to an inoperative position, wherein said vertically elevating means comprises, a bracket attached to said hinge means, a threaded rod supported in said bracket, and a support bar fastened on said guide and threaded to said threaded rod, whereby rotation of said threaded rod vertically moves said support bar and therefore said guide from one horizontal elevation to another.

Claim 14

A means having a saw fence and a saw for uniformly altering the distance between a table saw surface and an associated work guide comprising in combination: attachment means connecting said guide to the fence, vertical elevation means between said attachment means and said guide to elevate the guide from one horizontal elevation to anther relative to the table saw surface, and hinge means parallel to the cutting direction of the saw connecting said elevation means to said attachment means to move said guide from an operative to an inoperative position, wherein said vertically elevating means comprises, a bracket attached to said hinge means, a threaded rod supported in said bracket, and a support bar fastened on said guide and threaded to said threaded rod, whereby rotation of said threaded rod vertically moves said support bar and therefore said guide from one horizontal elevation to another.

Claim 15

The device of claim 10, wherein said threaded rod includes handle means on an extremity thereof for rod rotation and therefore guide motion.

Claim 16

The device of claim 11, wherein said threaded rod includes handle means on an extremity thereof for rod rotation and therefore guide motion.

Claim 17

The device of claim 11, wherein said clamp means is defined by an inverted substantially U-shaped bracket overlying the fence, and a further threaded rod extending through said U-shaped bracket in clamping engagement with the fence wherein said hinge means includes an L-shaped upper piece, having a vertical leg affixed to said C-shaped bracket, a horizontal leg overlying a top face of the fence, a hinge connected to said horizontal leg remote from said vertical leg, a lower piece affixed to said U-shaped bracket and connected at said hinge area to said upper piece whereby said hinge is on a side of the fence remote from the saw for clearance when said device is rotated into an inoperative position.

Claim 18

The device of claim 12, wherein said clamp means is defined by an inverted substantially U-shaped bracket overlying the fence, and a further threaded rod extending through said U-shaped bracket in clamping engagement with the fence wherein said hinge means includes an L-shaped upper piece, having a vertical leg affixed to said C-shaped bracket, a horizontal leg overlying a top face of the fence, a hinge connected to said horizontal leg remote from said vertical leg, a lower piece affixed to said U-shaped bracket and connected at said hinge area to said upper piece whereby said hinge is on a side of the fence remote from the saw for clearance when said device is rotated into an inoperative position.

Claim 19

In a table saw of the type having a table, a saw blade extending upwardly through an opening in the table, and a fence on the table laterally of the blade, the improvement which comprises an overhead fence assembly including a guide member extending above the table and substantially covering the blade for improved safety, the guide member having a side leading edge, whereby a template carried on top of a workpiece engages the side leading edge of the guide member as the workpiece is pushed through the saw blade, whereby the workpiece substantially duplicates the template, means for vertically adjusting the position of the guide member relative to the table, and means for hingedly mounting the guide member on the fence, whereby the guide member is adapted to swing away from the blade to facilitate the cleaning of the cut scraps off the table.

Claim 20

In a table saw of the type having a table, a saw blade extending upwardly through an opening in the table, and a fence on the table laterally of the blade, the improvement which comprises an overhead fence assembly including a guide member extending above the table and substantially covering the blade for improved safety, the guide member having a side leading edge, whereby a template carried on top of a workpiece engages the side leading edge of the guide member as the workpiece is pushed through the saw blade, whereby the workpiece substantially duplicates the template, means for vertically adjusting the position of the guide member relative to the table, and means for hingedly mounting the guide member on the fence, whereby the guide member is adapted to swing away from the blade to facilitate the cleaning of the cut scraps off the table.
