Table saw fence engagement and blade guard apparatus

A fence engagement and blade guard a comprising:

• a column mounted to a table saw;
• a horizontal member received in a channel in the column and adjustably extending therefrom;
• a vertical rod extending through and vertically adjustable in a hole in the horizontal member distal from the column:
• and,
• an engagement cart suspended from the vertical rod and including a beam having vertically at least two elongated axle apertures,
• at least two axles received in the apertures,
• an axle suspension system supporting a shield, said axle suspension system having an axle nut with a threaded nipple received in a threaded hole in the beam centered over the axle aperture and an alignment bore with a cup receiving a pin extending through a port in the axle and received in a notch in the beam,
• wherein each axle incorporates vertical flat surfaces on an engagement portion received within the axle aperture, said axle aperture having associated flats to constrain rotation of the axle to a vertical plane and said port in the axle is dual tapered for angular play of the pin for rotation of the axle;
• at least one wheel supported by each of said axles, said wheel frictionally engaging a work piece, and,
• a spring concentric with the pin and captured within the alignment bore of the axle nut, said spring constrained between a shoulder of the alignment bore and each axle urging the axle downwardly within the axle apertures, said engagement cart angularly rotatable for engagement of the wheels on the work piece to directionally urges the work piece.
