Abstract
Abstract A bench or table saw includes an elongate slot extending across a substantial portion of the width of the table surface and a powered saw movably mounted beneath the table. The cutting blade of the saw projects upward through the slot and is movable along the slot for cutting the work to be cut, the latter of which is held stationary on the table surface. An adjustable work holder is attached to the table surface for adjusting the angle of the work to be cut relative to the elongate slot and the angle at which the cutting blade projects through the slot may be adjusted, whereby the work to be cut may be simple or compound mitered.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
242 words
A table saw comprising: frame means, a planar rigid table surface mounted on said frame means, an elongate slot defined in said surface and extending across a substantial portion of the width of said surface, powered saw means including a cutting blade, mounting means mounting said saw means beneath said surface such thaT said cutting blade projects upward through said slot and above said surface, said mounting means including a pair of elongate spaced rods extending parallel to said slot beneath said surface, said saw means being longitudinally movable along said rods and the length of said slot relative to the work to be cut, a pair of first and second plate means each having complementary interfitting arcuate ridges and grooves in adjacent facing surfaces thereof, said first plate means of each said pair being stationarily mounted to said frame means adjacent opposite ends of said slot, said second plate means of each said pair being mounted to said first plate means by said interfitting arcuate ridges and grooves and supporting said elongate rods thereon, one of said ridges and grooves being selectively movable relative to the other to selectively vary the angle at which said cutting blade projects through said slot about an axis parallel to said slot, and work holder means stationarily mounted to said surface for positioning the work to be cut in the path of movement of said cutting blade as said blade is moved along said slot.
Claim 2
Dependent Claim
242 words
A table saw comprising: frame means, a planar rigid table surface mounted on said frame means, an elongate slot defined in said surface and extending across a substantial portion of the width of said surface, powered saw means including a cutting blade, mounting means mounting said saw means beneath said surface such thaT said cutting blade projects upward through said slot and above said surface, said mounting means including a pair of elongate spaced rods extending parallel to said slot beneath said surface, said saw means being longitudinally movable along said rods and the length of said slot relative to the work to be cut, a pair of first and second plate means each having complementary interfitting arcuate ridges and grooves in adjacent facing surfaces thereof, said first plate means of each said pair being stationarily mounted to said frame means adjacent opposite ends of said slot, said second plate means of each said pair being mounted to said first plate means by said interfitting arcuate ridges and grooves and supporting said elongate rods thereon, one of said ridges and grooves being selectively movable relative to the other to selectively vary the angle at which said cutting blade projects through said slot about an axis parallel to said slot, and work holder means stationarily mounted to said surface for positioning the work to be cut in the path of movement of said cutting blade as said blade is moved along said slot.
Claim 3
Dependent Claim
44 words
The table saw of claim 1 wherein said work holder means extends at a substantial angle to the path of movement of said cutting blade and includes means for selectively varying said angle such that the work to be cut may be selectively mitered.
Claim 4
Dependent Claim
98 words
The table saw of claim 2 wherein said work holder means includes first and second elongate fence portions, first fastening means for stationarily fastening said first fence portion to said surface and parallel to said slot, hinge means pivotally mounting said second fence portion to said first fence portion, said second fence portion extending at an angle to said first fence portion which may be selectively varied by pivoting said second fence portion about said hinge means, and second fastening means for fastening said second fence portion to said surface at at least one of the selected angles.
Claim 5
Dependent Claim
60 words
The table saw of claim 1 wherein said work holder means extends at a substantial angle to the path of movement of said cutting blade and includes first means for selectively varying said angle, whereby when the angle at which said cutting blade projects through said slot is also selectively varied, the work to be cut may be compound mitered.
Claim 6
Dependent Claim
24 words
The table saw of claim 1 wherein said mounting means includes locking means for locking said cutting blade adjacent one end of said slot.
Claim 7
Dependent Claim
31 words
The table saw of claim 1 including means for moving said saw means in elevation to adjust the distance by which said cutting blade projects from said slot above said surface.
