  • Patent number: 5214830
    Abstract: An apparatus for recycling used oil filters is disclosed wherein an oil filter canister of the type having a base portion and a cover portion enclosing a pleated filter element is placed in a separating means wherein the filter cover is separated or cut from the filter base to expose the pleated filter element. The oil filter cover is sent to a crusher, while the pleated filter element is sent to a spin means or centrifuge to remove excess oil therefrom. Miscellaneous parts are then removed from the oil filter and sent to scrap bin. The pleated filter element, having the oil removed, is suitable for use in landfills. The separating means and the spin means provide for the collection of used motor oil in an oil reservoir.
