Abstract
Abstract A work holder for vertical band saws wherein a moving blade is laterally translated through a work table slot. The work holder includes a fixed reference member mounted on the table transversely disposed to the table slot and intersected by the blade. A clamp mounted upon the work table in alignment with the slot bridges the slot and saw blade path of movement holding the workpiece against the reference member permitting firm retention of the workpiece adjacent the blade to permit small pieces to be accurately severed.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
179 words
A saw comprising, in combination, a frame, a substantially flat table mounted on said frame having an edge, an elongated table slot defined in said table intersecting said edge, a saw blade, gravity operated saw blade support means mounted on said frame supporting said saw blade for selectively moving said saw blade through said table slot, an elongated reference member fixed to said table adjacent said table edge extending substantially perpendicular to said table slot and comprising first and second aligned elongated portions disposed on opposite sides of said table slot in close proximity thereto whereby said saw blade moves through said reference member when moving through said table slot, a clamp support mounted upon said table spaced from said reference member, and a clamp head mounted on said clamp support in alignment with said table slot and movable in the direction of the length of said table slot toward and away from said reference member, said clamp head straddling said table slot and adapted to clamp a workpiece against said reference member in alignment with said table slot.
Claim 2
Dependent Claim
179 words
A saw comprising, in combination, a frame, a substantially flat table mounted on said frame having an edge, an elongated table slot defined in said table intersecting said edge, a saw blade, gravity operated saw blade support means mounted on said frame supporting said saw blade for selectively moving said saw blade through said table slot, an elongated reference member fixed to said table adjacent said table edge extending substantially perpendicular to said table slot and comprising first and second aligned elongated portions disposed on opposite sides of said table slot in close proximity thereto whereby said saw blade moves through said reference member when moving through said table slot, a clamp support mounted upon said table spaced from said reference member, and a clamp head mounted on said clamp support in alignment with said table slot and movable in the direction of the length of said table slot toward and away from said reference member, said clamp head straddling said table slot and adapted to clamp a workpiece against said reference member in alignment with said table slot.
Claim 3
Dependent Claim
24 words
In a saw as in claim 1, said clamp head having a face firmly engaging the workpiece on each side of said table slot.
Claim 4
Dependent Claim
26 words
In a saw as in claim 2, said clamp support including a lock, said lock locking said clamp head in predetermined relationship to said reference member.
Claim 5
Dependent Claim
55 words
In a saw as in claim 2, bolts affixing said clamp support to said table, an elongated rod axially slidably mounted upon said clamp support in alignment with said table slot, a lock defined on said clamp support locking said rod with respect to said clamp support, said clamp head being mounted upon said rod.
Claim 6
Dependent Claim
78 words
In a saw as in claim 1, said reference member including a workpiece engaging face disposed toward said clamp support, an indicia measurement scale defined upon said face, a stop mounted upon said face and means adjustably mounting said stop on said face comprising a slot defined in said stop substantially parallel to said reference member, and a releasable fastener extending through said stop slot attached to said reference member frictionally holding said stop against said reference member.
