Abstract

Abstract A table saw including a top having a vertical powered rotary saw blade journaled from the table with its lower peripheral portion spaced slightly above the upper surface of the top thereof. A floating work support panel is provided and the tabletop and panel include coacting structure supporting the panel from the top in overlying relation relative to the top for guided rectilinear horizontal shifting along a path normal to the axis of rotation of the blade. The lower periphery of the blade projects slightly below the upper surface of the panel and the panel has a shallow upwardly opening groove formed therein aligned with and in which the lower periphery of the blade is receivable when the work supporting panel is shifted toward the blade. Also, workpiece supporting structure is carried by the panel for supporting a workpiece in predetermined position thereon with a portion of the workpiece overlying the groove, whereby the panel, with the workpiece supported therefrom, may be shifted toward the blade in order to cut the workpiece along a vertical plane containing the groove formed in the panel in which the lower periphery of the blade is receivable. Also, the workpiece supporting structure carried by the panel is operative to adjustably angularly displace the workpiece supported therefrom about a vertical axis contained in the plane in which the blade is disposed.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 194 words
In combination with a support table including a top and powered axially spaced rotary saw means journaled from said table with the lower peripheral edges of said saw means spaced above said top, a floating work support panel, said tabletop and panel including coacting means supporting said panel from said top in overlying relation relative thereto for guided rectilinear shifting along a central path normal to the axes of rotation of said saw means and centrally spaced between said rotary saw means, a pair of arm means including one pair of convergent ends pivotally supported from said panel for angular displacement about axes equally spaced from said central path on opposite sides thereof and generally disposed at generally right angles relative to said path and the axes of rotation of said saw means, said arm means including work engaging means for engaging workpieces disposed on said panel along said arm means and releasably retaining said workpieces in adjusted position relative to said arm means, said panel and arms including coacting adjustment means for inversely equally angularly displacing said arms relative to said panel with said arms oppositely and equally inclined relative to said path.
Claim 2
Dependent Claim 194 words
In combination with a support table including a top and powered axially spaced rotary saw means journaled from said table with the lower peripheral edges of said saw means spaced above said top, a floating work support panel, said tabletop and panel including coacting means supporting said panel from said top in overlying relation relative thereto for guided rectilinear shifting along a central path normal to the axes of rotation of said saw means and centrally spaced between said rotary saw means, a pair of arm means including one pair of convergent ends pivotally supported from said panel for angular displacement about axes equally spaced from said central path on opposite sides thereof and generally disposed at generally right angles relative to said path and the axes of rotation of said saw means, said arm means including work engaging means for engaging workpieces disposed on said panel along said arm means and releasably retaining said workpieces in adjusted position relative to said arm means, said panel and arms including coacting adjustment means for inversely equally angularly displacing said arms relative to said panel with said arms oppositely and equally inclined relative to said path.
Claim 3
Dependent Claim 29 words
The combination of claim 1 wherein said coacting means includes parallel guideway and rail means guidingly and slidingly received in said guideway means on said tabletop and support panel.
Claim 4
Dependent Claim 15 words
The combination of claim 2 wherein said panel member is slightly spaced above said tabletop.
Claim 5
Dependent Claim 25 words
The combination of claim 1 wherein said arm means include clamp means for clamping a workpiece thereto along one longitudinal edge of said arm means.
Claim 6
Dependent Claim 50 words
The combination of claim 4 wherein said arm means include longitudinally extending plate means overlying the upper surfaces thereof and supported from said arm means for adjustable lateral shifting relative to said arm means as well as extension and retraction relative to one longitudinal edge portion of said arm means.
Claim 7
Dependent Claim 73 words
The combination of claim 5 wherein said arm means include slide means mounted thereon for adjustable positioning therealong, said slide means including an abutment member projecting horizontally outwardly of said one longitudinal edge portion of said arm means and including an abutment surface facing generally toward the axis of angular displacement of said arm means, said abutment member being supported from said slide means for limited angular displacement relative to said slide means.
Claim 8
Dependent Claim 40 words
The combination of claim 6 wherein said arm means includes removable extension means on one end thereof, the axis of angular displacement of said arm means relative to said panel being disposed adjacent the other end of said arm means.
