Abstract
ABSTRACT OF THE DISCLOSURE
A plug for a lubricant casing including an outer adapter threadedly connected to the casing having a closure wall at one end and an open flanged end at its other end threadedly receiv-ing a plug containing a strong electromagnetic. The outer adaptor has a pair of ports permitting lubricant to flow through the adapter into the influence of the electromagnetic field to remove metal filings from the lubricant. The adapter can be unthreaded partially from the casing and the inner plug removed for cleaning. The closure wall of the adapter prevents drainage of lubricant from the casing during cleaning of the inner plug.

Description
BACKGROUND O~ THE INVENTION
__ This invention relates to a plug adapted to be inserted in the drain or fill opening of a crankcase, trans-mission housing, di~ferential housing, or other article of machinery containing oil and moving parts, the plug being provided with an electromagnet ~or attracting any broken pieces of metal or other parti,cles of metal produced by wear of the parts.
Often, magnetic particles or filings break off from a machine and are carried along with a lubricant for the moving parts of a machine. These ~ilings, if not removed from the lubricant can damage the bearings and other parts of the machine.
Accordingly, this invention provides a plug insertéd in a lubri-cant casing for attracting such magnetic parti les from the lubricant, which plug may be removed for inspection and cleaning without drainage of the lubricant from the casing.
_ MMARY OF THE INVENTION
In accordance with the invention, a hollow, exterior mounting adapter is threadedly connected to a drain opening in a lubricant casing, such as a crankcase. The adapter has an inner closure end wall and is provided with a pair of opposite ports in the sidewall thereof enabling co~nunication between the interior of the adapter and the interior of the lubricant casing~
The adapter has an open exterior flanged end opposite the closure wall for locating the adapter in the lubricant casing and an 1 ;:
electromagnetic plug threadedly received in the open end of the adapter. The adapter is threaded into the casing with the plug and lubricant passing through the ports in the adapter. Any metal filings in the lubricant will be attracted to the electro- i magnet The adapter and plug can be partially threaded out of the casing wherein the closure end wall of the adapter will pre-vent drainage from the casing and the inner plug removed to clean , q;l 3 the filin~s ~cc~l~ulated on the electroma~net fxo~ the assembly.
BRIEF DESCRI~T~ON ~F THE DR~WINGS
Further ob~ects and advantages of the invention will become apparent from the ~ollowing description and claims, and from the accompanying drawings, wherein:
Figure 1 is a sectional view through an adapter and electromagnetic plug assembly mounted in a lubricant containing casing wall opening, the casing wall being shown in fragmentary section only; and Figure 2 is a sectional view similar to that of Figure 1, but showing the adapter in its outwardly adjusted position and the electromagnetic plu~ partially removed from the adapter.
DETAILED DESCRIPTION OF ~HE PREFERRED EMBODIMENT
Referring nbw to the drawlngs in detail, wherein like numerals indicate like elements throughout the several views, the -present invention comprises an electromagnetic plug 10 threadedly mounted in the exteriox open end 12 of an adapter plug 14, The adapter 14 is formed with an exterior flange 16 and an inner closed end 18 having ports 20 located in the side wall of the adapter 14 adjacent the inner closed end 18 thereof. The ports 20 communicaté with the hollow intérior or chamber 22 of the adapter 14 so that lubricant 24 flowing into this chamber ~2 by way of ports 20 will pass within the magnetic field or influence of an electromagnetic element 26 carried by the magnetic plug 10.
The assembled adapter 1~ and magnetic plug 10 is shown threadedly connected in an opening 23 of a lubricant containing casing 30. It should~be understood that the casing 30 may con-sist of a part of an engine crankcase, a lubricant conduit, or other wall means defining a flow path for a lubricant or con- ~
taining a lubricant to direct or confine its movement, whether -of a continuous or intermittent character.
The ~osition o~ the adapter and magnetic plug shown in - . . ~ ~ : . ; : . -Figure 1 illustrates the normal operatiVe position of the magnetic plug 10. On the 4ther hand, ln Figure 2 the adapter 14 is shown in its out~rdly ad~usted position rel~tive to the opening 28 in the casing 30 so that the closed inner end 18 is positioned substantially in the opening 28 to act as a plug or closure for the opening to prevent escape of lubricant. The magnetic plug 10 can safely be removed from the adapter 14 for inspection and cleaning when thé adapter 14 is adjusted to the outward postion shown in Figure 2.
The advantage of the adapter 14 resides in the pro-vision of the inner closure wall 18 which acts as a substitute :
plug or closure for the casing opening 28 when the magnetic plug -~
10 is removed, and the use of a moderately strong electromagnet that enables the creatlon of a high powered field or a variable field to remove metallic particles 32 that might otherwise escape.
The electromagnet could operate off the battery of a vehicle ~:
(e.g. if plug 10 is connected to a crankcase) by connecting the leads in wire covering 34 to the electromagnet to the battery or any other source of electrical energy.
While a specific embodiment of an electromagnetic plug has been disclosed in the foregoing description, it will be understood that various modifications within the spirit of the invention may occur to those skilled in the art. Therefore, it is intended that no limitations be placed on the invention except as defined by the scope of the appended claims.
