Abstract: A protective device for the top surface of a slotted milling machine table preferably comprises a rubber cover sized to overlay a desired length of the table at one end thereof, the surfaces of the cover each having a raised peripheral lip and longitudinally extending beads and ribs. The downwardly directed beads fit within the slots of the milling table to hold the cover in place while the downwardly directed ribs provide air space between the placed cover and the table, thereby inhibiting rust. The upwardly directed raised lip prevents coolant spillage from the top of the cover while the coolant return holes enable excess coolant to be returned to the slots residing therebeneath. To provide protection for a reduced length table, the cover is made reversible by providing a transverse lip portion on one of the surfaces, located inboard of the coolant return holes.

Abstract: A drilling fixture for drilling either cylindrical or flat workpieces on or off center is disclosed. The fixture includes a base having a V-shaped groove for receiving larger cylindrical workpieces, a pair of smaller V-shaped openings in the side walls of the base for receiving smaller cylindrical workpieces, a cover attached to the base, and a rotatable, indexable drill bushing mounted to the cover. The larger and smaller V-shaped grooves intersect at a common workpiece center-line drilling point. Thumbscrews are provided to clamp the workpieces in the grooves. The drill bushing includes a series of different size drill guide holes spaced about the circumference of the bushing on a common radius for receiving predetermined drill bit diameters to guide the drill bits along their longitudinal axes during a drilling operation.
