Magnetic assembly to applied against an oil filter

Abstract

A magnetic device for attachment to an exterior wall of an oil filter canister whose purpose is to attract ferrous particles being conducted through the oil passing through the oil filter canister and cause such to be adhered to the inner wall surface of the sidewall of the oil filter canister. The device has an enclosing frame within which is mounted a series of thin walled plates. The plates are located in a stacked relationship. The plates permit flexing of the enclosing frame so that a plurality of magnets that are mounted in conjunction with the frame will always be located flush against the exterior wall surface of the canister even though the diameter of the canister may vary by the canisters being constructed by different manufacturers. The magnets are coated with a plastic coating to prevent contact with moisture to prevent rusting of the magnets. Abutting surfaces of the magnets are prevented from direct contact by the use of a thin plastic strip to thereby prevent degradation of the coating and exposing of the surface of the magnets to the ambient conditions which could also cause rust. A lanyard may be provided as a safety harness to connect the device to an exterior structure.
