Abstract
A top cover for oilers having an aperture centrally located about a disc-shaped body through which a lubricating fluid may be dispensed into the reservoir of the oiler is provided. Such a cover has an advantage in that a larger filling aperture is thus attained thereby providing for more efficient filling of the oiler reservoir and is further attained at no cost as a by-product of other necessary machining.
