## Title
Aluminum oil pan filter bracket

## Abstract

A magnet holding bracket has an rectangular body for holding a rectangular magnet as defined by the Magnet Patent. A mounting tab on one end of the rectangular body includes an aperture sized and physically disposed for insertion of an oil pan drain plug from a non-ferrous oil pan. The drain plug tightens against the mounting tab and holds the rectangular magnet in justaposition to the non-ferrous oil pan such that the rectangular magnet can engage ferrous particles circulating within the oil pooling in the non-ferrous oil pan.

## Background
This application claims priority from Provisional Application Ser. No. 61/801,842, filed Mar. 15, 2013.


BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to oil filters for internal combustion engines, and particularly to micronic filters that utilize magnets to draw minute metal particles from engine oil supplies. More particularly, this invention relates to a bracket adapted to attach a micronic filter to an aluminum oil pan to which the magnetic filter otherwise cannot adhere.
2. Description of Related Art
U.S. Pat. No. 5,314,625 issued to Applicant, Michael Farnelli, on May 24, 1994, based on Application Serial No. 998,411 filed Dec. 29, 1992 (the “Magnet Patent”). The Magnet Patent describes a planar magnet with a C-channel housing adapted to magnetically adhere to a steel oil pan for an internal combustion engine. The Magnet Patent is hereby incorporated by reference in its entirety.
Many internal combustion engines these days, however, have aluminum or other non-ferrous oil pans in lieu of the more conventional steel oil pans. The magnetic filtering device of the Magnet Patent cannot adhere to such non-ferrous oil pans. A need exists for apparatus and method for adhering the magnetic filtering device of the Magnet Patent to non-ferrous oil pans and to other objects as appropriate for the intent and purpose of the Magnetic Patent.
SUMMARY OF THE INVENTION
A magnet holding bracket has a rectangular body for holding a rectangular magnet as defined by the Magnet Patent. A mounting tab on one end of the rectangular body includes an aperture sized and physically disposed for insertion of an oil pan drain plug from a non-ferrous oil pan. The drain plug tightens against the mounting tab and holds the rectangular magnet in juxtaposition to the non-ferrous oil pan such that the rectangular magnet can engage ferrous particles circulating within the oil pooling in the non-ferrous oil pan.



BRIEF DESCRIPTION OF THE DRAWINGS
The novel features believed characteristic of the present invention may be set forth in appended claims. The invention itself, however, as well as a preferred mode of use and further objects and advantages thereof, will best be understood by reference to the following detailed description of an illustrative embodiment when read in conjunction with the accompanying drawings, wherein:
FIGS. 1-3, 5 show a preferred embodiment of the present invention in plan, left side, end and bottom elevational views, respectively.
FIG. 4 shows the embodiment of FIG. 1 in a quartering perspective view.
FIGS. 6-8 depict alternate embodiments of the present invention adapted to couple two, three and six rectangular magnets, respectively, to a non-ferrous object.
FIGS. 9-10 show an alternate embodiment of the present invention.
FIGS. 11-14 show various views of the present invention with a rectangular magnet properly mounted onto a non-ferrous oil pan.



DETAILED DESCRIPTION OF A PREFERRED EMBODIMENT
With reference now to the figures, and in particular to FIGS. 1-5, magnet holding bracket 20 comprises elongate, C-channel shaped body 21 having back 24 flanked by legs 26 and extending from butt 22 to head 25. Neck 23 couples head 25 to body 21, and eye aperture 27 is disposed within head 25 and longitudinally aligned with body 21 and neck 23. As depicted, neck 23 forms an offset to displace planar head 25 from being coplanar with back 24, but remaining parallel thereto. In many non-ferrous oil pans, the lug or aperture where drain plug 3 attaches is oriented such that drain plug 3 must be substantially normal to the plane occupied by back 24. Bracket 20 is adapted to hold one magnetic filter 10 in juxtaposition to non-ferrous oil pan 1 (see FIGS. 11-14).
Turning now also to FIGS. 6-8, alternate embodiments of the present invention vary from bracket 20 by being capable of holding multiple magnetic filters 10 instead of a single one. In FIG. 6, bracket 30 holds two magnetic filters 10 disposed side-by-side and transverse a longitudinal axis A of bracket 30. This of course requires that channel 31 of bracket 30 be wider than channel 21 of bracket 20. In similar fashion, FIG. 7 depicts bracket 40 adapted to hold three magnetic filters 10 disposed side-by-side and transverse longitudinal axis A of bracket 40, again necessitating that channel 41 thereof be even wider. FIG. 8 depicts yet another embodiment of bracket 50 adapted to hold six magnetic filters 10 in two rows of three each, each row disposed side-by side and transverse longitudinal axis A of bracket 50. In this case, the geometry requires that channel 51 of bracket 50 be as wide as channel 41 of bracket 40, but twice as long.
Turning now to FIGS. 9-10, the preferred embodiment of the present invention, bracket 20, is shown in various perspective views as having neck 23 disposed at an angle relative to back 24 instead of the parallel offset configuration of FIGS. 1-3, 5. In this case, the lug or drain hole into which drain plug 3 attaches is not positioned on the bottom of oil pan 1 but at an angle thereto, requiring that head 20 be disposed in a plane angled relative to the plane of back 24. One having ordinary skill in the art will recognize that many variations of this angle will be encountered, and that neck 23 must either be formed to reflect them or bent during installation.
Turning now to FIGS. 11-14, bracket 20 is shown installed on oil pan 1 and holding magnetic filter 10 in parallel juxtaposition to the bottom of oil pan 1 where it can attract ferrous shavings and particles within oil pooling on the bottom of oil pan 1.
The present invention, when used in conjunction with the above apparatus, enables magnetic filters 10 to cleanse oil pooling and circulating through non-ferrous oil pans 1. One having ordinary skill in the art will recognize that other uses for brackets 20, 30, 40, 50 may be derived from the principles and methods described herein.
While the invention has been particularly shown and described with reference to preferred and alternate embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention. For example, brackets 20, 30, 40, 50 have been presented as being used on non-ferrous oil pans, but they also could be employed just as well on oil pans of ferrous materials, or on other containers other than oil pans.
