Assembly to Operate a Reciprocating Saw Blade From a Rotating Shaft

An assembly for operating a reciprocating saw blade through a rotating shaft of a table saw, the assembly comprising:

• first and second coupling elements for receiving the saw blade, wherein the first and second coupling elements are rotatably coupled to the rotating shaft of the table saw for rotation in unison therewith and at a same angular speed along respective different radii and paths;
• the assembly being mounted to a table of the table saw so that i) one of the first and second coupling elements which is furthermost away from the table is movable along a larger circle than the other coupling element and ii) lines intersecting both circular paths during rotation of the first and second coupling elements converge at a fixed position above the table;
• whereby, in operation, the reciprocating saw blade is caused by the rotating shaft to reciprocate relative to the table with an angle that varies with a reciprocating direction of the saw blade relative to the table;
• the angle remaining acute relative to a corresponding one of a top and bottom surfaces of the table towards which the blade moves.
