TECHNICAL FIELD
The tool for oil filter drainage relates to the field of removing fluid from containers, and more particularly to a tool for insertion into the wall of a container with fluid, i.e. an oil filter, to permit the fluid to be controllably drained from the oil filter, before the oil filter is removed from the motor or machinery, to avoid leakage of the fluid from the oil filter.
BACKGROUND OF THE INVENTION
Lubrication systems in machinery, aircraft and vehicles require that their lubricants, viz., oil, and oil filters be replaced periodically in order to maintain the good working order of the engine and machinery. For passenger automobiles, many mechanics recommend a oil and filter change every 3,000 miles of travel to maintain maximum engine life. Professional truckers put thousands of miles on their trucks every week and wait many, many hours for oil changes over the course of a year.
Replacing the oil in a motor vehicle typically involves placing a large oil drain basin under the oil pan, removing the drain plug, thereby allowing the oil to drain therein, and unscrewing the oil filter from the engine block. Due to designs of most engines, it has been difficult to remove oil filters without spilling oil onto the frame of the vehicle, the vehicle engine, on the mechanics and/or the ground. This practice is not only messy, but is environmentally unsound. Since many oil changes are conducted when the oil is very hot, spillage from an oil filter upon removal also poses a safety hazard to mechanics.
Accordingly there is a need for a tool for oil filter drainage which is not only easy to use, simple in design, inexpensive to manufacture and which provides for leak proof operation, but which is designed to last a long term at a low cost.
It is thus an object of the tool for oil filter drainage to provide a novel control device for effectively containing oil from a filter upon removal of the filter from a vehicle engine and thus eliminating the environmental and safety issues associated with hot engine oil dripping onto the frame of the vehicle, onto the vehicle engine, onto mechanics and/or the ground.
It is a further object of the tool for oil filter drainage to provide a novel installation in which oil from an oil filter to be removed from a vehicle engine can be removed from the filter and safely diverted to a waste oil container.
It is still a further object of the tool for oil filter drainage to provide actuation of a piercing pin to quickly and effectively open the oil filter to allow waste oil flow into a containment vessel and exit the containment vessel through a channel which can be connected to a waste oil container.
It is yet still a further object of the tool for oil filter drainage to provide a novel tool for oil filter drainage which can be reused and/or connected quickly without extensive use of tools or knowledge of complex mechanical considerations.
Yet a further object of the tool for oil filter drainage is to provide a stoppage proof waste oil drain channel that eliminates an obstruction potential for typical spin-on type oil filters while the oil filter is still attached to a vehicle engine.
SUMMARY OF THE INVENTION
The tool for oil filter drainage provides a fluid container draining device which allows fluid to be removed from a fluid container in a controlled manner, the fluid container having walls defining a fluid filled interior region there between, the fluid container draining device having a round, magnetic end ring element attached to a central block body element. The central block body element contains an internal collection chamber, and a central axis with an axial bore along the central axis through the central block body element. The axial bore houses the piercing pin and a coil spring, including a striking surface, spring retainer, retaining clip groove, tapered point, and retaining clip. The central block body element internal chamber further provides a drainage channel from the internal chamber to outside the central block body element. The piercing pin is sized to extend beyond central block body element and into the central block body element internal chamber so as to sufficiently extend beyond the round, magnetic end ring element and through the metal wall of a spin-on oil filter attached to the round, magnetic end ring element when the piercing pin is struck on the striking surface. The piercing pin is fitted with a seal between it and the central block body element internal chamber. Further, the piercing pin is fitted with a retaining clip groove and retaining clip within the central block body element internal chamber to prevent the piercing pin from sliding out of the central block body element.
The tapered point of the piercing pin is suitable for piercing the exterior of an oil filter. The exterior portion of the piercing pin relative to central block body element includes a striking surface and retainer. The piercing pin is aligned in the axial bore of the central block body element so that the coil spring is between the retainer and the central block body element. In this manner, when force is applied to the striking surface, such as a blow from a hammer, the piercing pin is returned to its original position by compression of the coil spring between the retainer and the central block body element.
The drainage channel from the internal chamber to outside the central block body element is sized to be connected to standard hose or tubing to direct the flow of the waste oil from the oil filter through the internal chamber to an oil drain pan or other collection reservoir for waste engine oil.
Thus, the tool for oil filter drainage provides a central block body element with a round, magnetic end ring element suitable for attachment to a metal oil filter on a vehicle engine. Once the central block body element is so attached to the oil filter, the piercing pin striking surface is struck with force sufficient to overcome the tension of the coil spring, and the piercing pin tapered point travels along the axial bore of the central block body element, through the through the internal chamber, past the round, magnetic end ring element, piercing into and through the oil filter wall. As the coil spring returns the piercing pin to the original position before the striking force was applied to the piercing pin striking surface, waste oil flows from the punctured oil filter into the internal chamber, out the drainage channel, through a hose or tube connected to the drainage channel, and into a waste oil drain pan or containment reservoir.
An alternate embodiment of the tool for oil filter drainage provides a fluid container draining device having a cylindrical central body element and corresponding cylindrical internal chamber.

BEST MODE FOR CARRYING OUT THE INVENTION
Referring to FIGS. 1 through 11, wherein like reference numerals refer to like components in the various views, there is illustrated therein a new and improved tool for oil filter drainage. These views collectively show that the tool for oil filter drainage is adapted for a wide range of internal combustion vehicle engines having threaded spin-on type oil filters.
An embodiment of the tool for oil filter drainage provides a round, magnetic end ring element 16 attached to a central block body element 12, FIGS. 1-6. The central block body element 12 contains an internal collection chamber 90, and a central axis with an axial bore along the central axis through the central block body element 12, FIGS. 2 and 4-6. The axial bore houses the piercing pin 14 and a resilient spring 70, including a striking surface 30, spring retainer 40, retaining clip groove 50, tapered point 60, and retaining clip 80, FIGS. 1-6.
The central block body element 12 internal chamber 90 further provides a drainage channel 18 from the internal chamber to outside the central block body element 12, FIGS. 1-6. The piercing pin 14 is sized to extend beyond central block body element 12 and into the central block body element 12 internal chamber 90 so as to sufficiently extend beyond the round, magnetic end ring element 16 and through the metal wall of a threaded spin-on type oil filter attached to the round, magnetic end ring element 16 when the piercing pin 14 is struck on the striking surface 30. The piercing pin 14 is fitted with a seal between it and the central block body element 12 internal chamber 90. Further, the piercing pin 14 is fitted with a retaining clip groove 50 and retaining clip 80 within the central block body element 12 internal chamber 90 to prevent the piercing pin 14 from sliding out of the central block body element 12, FIG. 4.
The tapered point 60 of the piercing pin 14 is suitable for piercing the exterior of an oil filter 200. The exterior portion of the piercing pin 14 relative to central block body element 12 includes a striking surface 30 and retainer 40. The piercing pin 14 is aligned in the axial bore of the central block body element 12 so that the resilient spring 70 is between the retainer 40 and the central block body element 12. In this manner, after force has been applied to the striking surface 30, such as a blow from a hammer, to drive the tapered point 60 into the oil filter side, the piercing pin 14 is returned to its original position by the force from compression of the coil spring 70 between the retainer 40 and the central block body element 12, FIGS. 4 and 5.
The drainage channel 18 from the internal chamber 90 to outside the central block body element 12 is sized to be connected to standard hose or tubing (not shown) to direct the flow of the waste oil from the oil filter through the internal chamber 90 to an oil drain pan or other collection reservoir (not shown) for waste engine oil.
Thus, the embodiment of the tool 10 for oil filter drainage for FIGS. 1-6, provides a central block body element 12 with a round, magnetic end ring element 16 suitable for attachment to a metal, threaded spin-on type oil filter on a vehicle engine. Once the central block body element 12 is so attached to the oil filter, the piercing pin 14 striking surface 30 is struck with force sufficient to overcome the tension of the coil spring 70, and the piercing pin 14 tapered point 60 travels along the axial bore of the central block body element 12, through the through the internal chamber 90, past the round, magnetic end ring element 16, piercing into and through the oil filter wall. As the coil spring 70 returns the piercing pin 14 to the original position before the striking force was applied to the piercing pin 14 striking surface 30, waste oil flows from the punctured oil filter into the internal chamber 90, out the drainage channel 18, through a hose or tube connected to the drainage channel 18, and into a waste oil drain pan or containment reservoir.
An alternate embodiment of the tool for oil filter drainage 110 includes a cylindrical central body element 112 having an magnetic end ring element 116 and an internal chamber 190, a central axis with an axial bore along the central axis through the central block body element 112, the axial bore housing a piercing pin 114 and a spring 170 assembly having a striking surface 130 and a retainer pin 140 and a threaded drainage channel 118 and threaded drain 120, FIGS. 7-10.

When the striking force is removed, the resilient spring 70 or 170 pushes the piercing pin 114 back from the oil filter 200 end, allowing gravity to pull oil from the pierced oil filter 200 end through the pierced portion of the oil filter end and into the oil receptacle housing oil collection chamber, 90 or 190, respectively. Gravity continues to induce the oil to flow out of the oil receptacle housing 12 or 112, respectively, through the drainage channel 18 or 118, 120 and into suitable waste oil storage receptacle (not shown) through a length of hose (not shown) having a first end affixed to the drainage channel 18 or 120 and a second end inserted into a waste oil storage receptacle.
The round, magnetic end ring element 16 or magnetic end ring element 116 may have varying thickness to accommodate differing oil filter contours, or to access an oil filter rounded side. Magnetic end ring element 16 or magnetic end ring element 116, as depicted in FIGS. 8-9, may have a convex face to accommodate the curved portion of the oil filter 200 end to which it will be attached.
The block body element 12 or cylindrical central body element 112 may further include a seal element for improving the seal between the oil filter 200 end and the central block body element 12 or cylindrical central body element 112. This seal element for an embodiment of the block body element 12 includes a groove 52 housing an O-ring 54 in the surface of the block element 12 within the round, magnetic end ring element 16 integral to the block body element 12, FIG. 11.
