Abstract
Abstract Precision cutting of cove molding in all commercial sizes and designs is obtained by an apparatus which includes a flat bed plate having a straight saw blade slot formed therethrough and a power saw guideway along the slot. A rest for cove molding extending away from one side of the saw blade slot at an angle of 45 degrees thereto includes opposite side flat surfaces which rise from the top of the bed plate at angles of 45 degrees to the bed plate, the rest having a flat bottom surface to engage the bed plate. As an attachment to existing saw table equipment, the cove molding rest may have a bottom recess including an end stop surface to fit over a protractor guide of the existing equipment. All customary angle cuts of the cove molding are greatly facilitated.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
89 words
An apparatus for cutting cove molding comprising a flat bed plate having at least one straight edge for the guidance of a saw blade, a cove molding rest on the bed plate disposed at an angle of 45 degrees to said straight edge and extending away from said edge in one direction, and said rest having a pair of flat parallel inclined upwardly converging side surfaces rising at angles of 45 degrees to the top face of the bed plate and extending for the entire length of said rest.
Claim 2
Independent Claim
89 words
An apparatus for cutting cove molding comprising a flat bed plate having at least one straight edge for the guidance of a saw blade, a cove molding rest on the bed plate disposed at an angle of 45 degrees to said straight edge and extending away from said edge in one direction, and said rest having a pair of flat parallel inclined upwardly converging side surfaces rising at angles of 45 degrees to the top face of the bed plate and extending for the entire length of said rest.
Claim 3
Dependent Claim
61 words
An apparatus for cutting cove molding as defined in claim 1, and said straight edge being defined by a straight saw blade slot in said bed plate extending across the longitudinal axis of said rest, and said rest having an end face normal to the plane of the bed plate and parallel to the slot and coinciding with said straight edge.
Claim 4
Dependent Claim
34 words
An apparatus for cutting cove molding as defined in claim 2, and a pair of closely spaced parallel precision guides for a saw blade on the bed plate, one guide defining said straight edge.
Claim 5
Dependent Claim
26 words
An apparatus for cutting cove molding as defined in claim 3, and a saw guideway on the bed plate along and parallel to said straight edge.
Claim 6
Dependent Claim
25 words
An apparatus for cutting cove molding as defined in claim 1, and a linear guideway for a saw along and parallel to said straight edge.
Claim 7
Dependent Claim
117 words
An attachment for a sawing table apparatus having saw guideway means and a protractor arm adapted to be locked at a 45 degree angle to the guideway means, the apparatus including a table member having a flat surface, said attachment comprising a cove molding rest having a flat bottom face to engage the flat surface of the table member and opposite side parallel upwardly converging flat surfaces rising at angles of 45 degrees from said flat bottom face, and said rest having a bottom recess adapted to fit over and receive therein said protractor arm whereby the arm will precisely position the rest on the table member in 45 degree angular relationship to said saw guideway means.
Claim 8
Dependent Claim
117 words
An attachment for a sawing table apparatus having saw guideway means and a protractor arm adapted to be locked at a 45 degree angle to the guideway means, the apparatus including a table member having a flat surface, said attachment comprising a cove molding rest having a flat bottom face to engage the flat surface of the table member and opposite side parallel upwardly converging flat surfaces rising at angles of 45 degrees from said flat bottom face, and said rest having a bottom recess adapted to fit over and receive therein said protractor arm whereby the arm will precisely position the rest on the table member in 45 degree angular relationship to said saw guideway means.
Claim 9
Dependent Claim
35 words
An attachment for a sawing table apparatus as defined in claim 6, and said rest having an angled end face normal to the flat surface of the table member and parallel to said guideway means.
Claim 10
Dependent Claim
50 words
An attachment for a sawing table apparatus as defined in claim 7, and said bottom recess having a blind end abutting the end of the protractor arm to thereby form a stop for the rest whereby the angled end face is positioned with precision in relation to said guideway means.
Claim 11
Dependent Claim
44 words
An attachment for a sawing table apparatus as defined in claim 6, and said rest being in the form of an elongated bar member and said opposite side upwardly converging flat surfaces being separated at the top of the rest by a top surface.
Claim 12
Dependent Claim
92 words
An attachment for a sawing table apparatus as defined in claim 6, and said saw guideway means including a saw blade slot, said rest having a 45 degree angled end face normal to the flat surface of the table member and adapted to coincide with one edge of said slot, said bottom recess having an end surface forming a stop for the rest in contact with an end surface of said protractor arm so that the 45 degree angled end face is caused to coincide with said one edge of said slot.
