Abstract
An oil filter recycler for severing the casing of an automotive oil filter, for separating the filter into its components for recycling, and for removing engine waste oil for environmentally safe disposal, characterized by a turntable for rotating a cylindrically shaped filter about its' axis and a knife for severing the casing of the filter as it is rotated. The turntable is rotatable either manually or automatically. The knife is radially adjustable relative to the axis of the turntable. A releasable ratchet pawl spring biased for engagement with a rotatable threaded rod on a slidable knife holder provides for slidable, rotatable adjustment of the knife, and for quick release and retraction of the knife.
