Abstract:
An apparatus for processing multiple used oil filters for an engine using oil for lubrication by shearing a connector plate of each filter from a canister and then crushing the canister which comprises:(a) a fixed wall in a frame against which a used oil filter is positioned in a crushing zone with the connector plate below the canister; (b) a movable wall mounted on the frame which is movable by a driving means to engage the filter in the crushing zone to crush the filter, and which is retracted by the driving means from the crushing zone; (c) blade means mounted adjacent to the movable wall or adjacent to the fixed wall so as to shear the connector plate from the canister as the movable wall crushes the canister against the fixed wall; (d) a floor mounted on the frame for the removal of the used oil the sheared connector plate and the crushed canister from the apparatus; and (e) a feed chute with an escapement means for individually and automatically feeding the oil filters to the crushing zone based upon the position of the movable wall wherein a retaining means holds a preceding oil filter of the multiple filters away from the crushing zone until the used oil, the crushed canister and the sheared connection plate have been removed from the crushing zone of the apparatus.
