Abstract:
1. A tool for draining oil from an oil filter prior to removal of the oil filter, the oil filter comprising a fluid connecting end, an opposite end comprising an external surface, and sides, the tool comprising in combination: a) an oil receptacle housing sized to be attached to only a portion of the external surface of the opposite end of the oil filter to be removed such that the oil receptacle housing contacts only a portion of the oil filter opposite end external surface without contacting or surrounding the oil filter sides, the oil receptacle housing comprising an internal oil collection chamber, an axial bore from an external surface of the oil receptacle housing to the internal oil collection chamber, an oil receptacle housing oil collection chamber open end, and a drainage channel from the internal oil collection chamber through the oil receptacle housing and extending from an oil receptacle end surface opposite from the open receptacle housing oil collection chamber end; b) a piercing pin sized to be received within the oil receptacle housing axial bore with a length portion of the piercing pin extending from the oil receptacle end opposite from the open receptacle housing oil collection chamber end, the piercing pin comprising a striking head end on the length portion of the piercing pin extending from the oil receptacle end opposite from the open receptacle housing oil collection chamber end, a tapered point end on a piercing pin length portion within the oil receptacle housing oil collection chamber open end, and a piercing pin retaining assembly on the piercing pin length portion within the oil receptacle housing oil collection chamber open end; c) a resilient spring retainer assembly; d) a resilient spring sized to receive a length portion of the piercing pin extending from the oil receptacle end opposite from the open receptacle housing oil collection chamber open end, between the spring retainer assembly and the external surface of the external surface of the oil receptacle housing; and e) magnetic means integral to the oil receptacle housing oil collection chamber open end for attaching the oil receptacle housing oil collection chamber open end to only a portion of the oil filter external surface; whereby when the oil receptacle housing is attached to only a portion of the oil filter end external surface, force applied to the striking head moves the piercing pin through the oil receptacle housing oil collection chamber to pierce a hole in the oil filter opposite end external surface surrounded by the oil receptacle housing, and once the striking force is removed the spring pushes the piercing pin back from the oil filter opposite end external surface, allowing gravity to pull oil from the pierced oil filter opposite end external surface through the pierced portion of the oil filter external surface and into the oil receptacle housing, and then to flow out of the oil receptacle housing through the drainage channel and into a waste oil storage receptacle through a length of hose having a first end affixed to the drainage channel and a second end inserted into a waste oil storage receptacle.
