Abstract
Abstract An improved, safer, more efficient saw table construction is provided in the present invention by channelled guide tracks which slidably support a tool and plate assembly in any one of two positions at right angles to each other. The tool can be readily moved from one position to another, without remounting the tool on the tool plate, by controllable withdrawal of the tool plate from the ends of the guide tracks, rotation of the entire tool and plate assembly, and reinsertion of the plate into the channelled tracks provided.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
282 words
A saw table for portable power saws and like tools comprising: a support having an upper flat surface upon which a workpiece may be supported; a square tool plate assembly adapted to support said saw or similar tool; a pair of elongated parallel tracks supported on said upper flat surface of said base, each of said tracks having ends and generally horizontally spaced longitudinally extending flanges extending between said ends, said flanges defining a channel therebetween in which said tool plate assembly is slidably supported for movement parallel to said tracks, said tracks spaced apart from each other to define an opening therebetween substantially equal in width to the width of said tool plate assembly whereby said tool plate assembly may be moved into and out of slidable engagement with said channels of said tracks and rotatable between two positions at right angles to each other by sliding said tool plate assembly beyond said ends of said tracks, rotating said tool plate assembly to the desired position and reinserting said tool plate assembly into said channels at said ends of said tracks; slidable guide members mounted on said tool plate assembly for slidably supporting said tool plate assembly for movement within said channels parallel to said tracks in any one of said two positions at right angles to each other, and a releasable stop member mounted within said channel of at least one of said tracks adjacent at least one of said ends of said track, comprising an L-shaped lever, mounting means for pivotally mounting said lever in said channel, and spring means for biasing said lever to a normally closed position to restrain withdrawal of said guide members from said channels.

Claim 3
Dependent Claim
263 words
A saw table for portable power saws and like tools comprising: a support having an upper flat surface upon which a workpiece may be supported; a square tool plate assembly adapted to support said saw or similar tool; a pair of elongated parallel tracks supported on said upper flat surface of said base, each of said tracks having ends and generally horizontally spaced longitudinally extending flanges extending between said ends, said flanges defining a channel therebetween in which said tool plate assembly is slidably supported for movement parallel to said tracks, said tracks spaced apart from each other to define an opening therebetween substantially equal in width to the width of said tool plate assembly whereby said tool plate assembly may be moved into and out of slidable engagement with said channels of said tracks and rotatable between two positions at right angles to each other by sliding said tool plate assembly beyond said ends of said tracks, rotating said tool plate assembly to the desired position and reinserting said tool plate assembly into said channels at said ends of said tracks; slidable guide members comprising nylon bearings mounted on said tool plate assembly for slidably supporting said tool plate assembly for movement within said channels parallel to said tracks in any one of said two positions at right angles to each other; and said nylon bearings having an upper cylindrical surface extending above said tool plate assembly and having a lower cylindrical surface wider in diameter than said upper cylindrical surface, said lower cylindrical surface being disposed below said tool plate assembly.
Claim 4

A saw table for portable power saws and like tools comprising: a support having an upper flat surface upon which a workpiece may be supported; a square tool plate assembly adapted to support said saw or similar tool; a pair of elongated parallel tracks supported on said upper flat surface of said base, each of said tracks having ends and generally horizontally spaced longitudinally extending flanges extending between said ends, said flanges defining a channel therebetween in which said tool plate assembly is slidably supported for movement parallel to said tracks, said tracks spaced apart from each other to define an opening therebetween substantially equal in width to the width of said tool plate assembly whereby said tool plate assembly may be moved into and out of slidable engagement with said channels of said tracks and rotatable between two positions at right angles to each other by sliding said tool plate assembly beyond said ends of said tracks, rotating said tool plate assembly to the desired position and reinserting said tool plate assembly into said channels at said ends of said tracks; slidable guide members comprising nylon bearings mounted on said tool plate assembly for slidably supporting said tool plate assembly for movement within said channels parallel to said tracks in any one of said two positions at right angles to each other; and said nylon bearings having an upper cylindrical surface extending above said tool plate assembly and having a lower cylindrical surface wider in diameter than said upper cylindrical surface, said lower cylindrical surface being disposed below said tool plate assembly.
Claim 5
Dependent Claim
27 words
A saw table as set forth in claim 2 wherein said guide members have a height substantially equal to the distance between the flanges of said tracks.
Claim 6
Dependent Claim
106 words
A saw table as set forth in claim 2 wherein three of said guide members are positioned along each of two opposite edges of said tool plate assembly with one said guide member positioned adjacent each of the corners of said tool plate and having its lower cylindrical surface extending outwardly of both of the edges of said tool plate assembly defining each corner for slidably supporting said tool plate assembly in any one of two of said positions at right angles to each other, and another said guide member intermediate said corner guide members on each of two opposite edges of said tool plate assembly.
