Abstract
Abstract A band saw is provided and includes a workpiece support table having a base portion which may be variably inclined and secured in adjusted inclined position with the base portion inclined downwardly in the direction in which a workpiece is to be advanced relative to the blade of the band saw. The workpiece support table further includes a workpiece support portion mounted on the base portion for rectilinear shifting along the path of inclination of the base portion of the support table. The workpiece support portion includes structure for clamping a workpiece thereto and the workpiece support portion is supported from the base portion for free rectilinear movement therealong, whereby the workpiece support portion will tend to move, by gravity, to the lower extremity of its movement relative to the base portion and a workpiece supported from the support portion may be gravity fed to the blade of the band saw.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
193 words
In combination, a saw including a base relative to which an elongated upstanding saw blade portion is longitudinally movable, a workpiece support table supported from said base, said support table including a base portion supported from said base for stationary angular adjustment about a generally horizontal axis extending transversely of the upstanding plane in which said blade portion is disposed and a table top supported from said base portion for guided shifting relative to said base portion along a path fixed relative to said base portion, disposed in said plane and angularly displaceable with said base portion relative to said base, said table top being supported from said base portion for guided gravity movement downwardly along said path, when the latter is inclined, and clamp means supported from said top for movement toward and aWay from the latter, said clamp means including a supportive holddown structure therefor mounted from said table top for adjustable shifting transversely of said path and substantially normal to said plane and having a mounting portion thereof spaced above said table top and relative to which said clamp means is adjustably shiftable toward and away from said table top.
Claim 2
Dependent Claim
193 words
In combination, a saw including a base relative to which an elongated upstanding saw blade portion is longitudinally movable, a workpiece support table supported from said base, said support table including a base portion supported from said base for stationary angular adjustment about a generally horizontal axis extending transversely of the upstanding plane in which said blade portion is disposed and a table top supported from said base portion for guided shifting relative to said base portion along a path fixed relative to said base portion, disposed in said plane and angularly displaceable with said base portion relative to said base, said table top being supported from said base portion for guided gravity movement downwardly along said path, when the latter is inclined, and clamp means supported from said top for movement toward and aWay from the latter, said clamp means including a supportive holddown structure therefor mounted from said table top for adjustable shifting transversely of said path and substantially normal to said plane and having a mounting portion thereof spaced above said table top and relative to which said clamp means is adjustably shiftable toward and away from said table top.
Claim 3
Dependent Claim
30 words
The combination of claim 1 wherein said mounting portion includes a clamp member supported therefrom for adjustable shifting toward and away from said table top relative to said mounting portion.
Claim 4
Dependent Claim
38 words
The combination of claim 2 wherein said clamp member includes a downwardly opening inverted generally V-shaped notch for embracingly receiving a workpiece disposed on said table top and to be clamped in position thereon by said clamp member.
Claim 5
Dependent Claim
105 words
The combination of claim 1 wherein said saw includes a pair of vertically spaced upper and lower blade support portions, said upper support portion including a plurality of guide means disposed in and spaced along an upwardly convex semi-circular path lying generally in an upright plane, said lower blade support portion including a plurality of guide means disposed in and spaced along a downwardly convex semi-circular path also lying generally in said upright plane, said upstanding saw blade portion including a portion of an endless band saw blade supported from said guide means for lengthwise advancement of said band saw blade about said semi-circular paths.
Claim 6
Dependent Claim
37 words
The combination of claim 4 including means supporting one of said support portions for adjustable angular displacement, relative to the other support portion, about an axis extending generally between the opposite ends of the corresponding semi-circular path.
