Abstract
An improved interlocked remote oil filter and drain provides a system for draining oil from the oil sump of an engine. The system comprises an improved interlock that includes an interlock tab movable between a drain position to permit draining of the engine oil when the oil filter is not in place and a safe position to prohibit draining of the engine oil when the oil filter is in place. The interlock tab allows the convenient use of different sizes and shapes of oil filters.
Claims9
In an interlocked oil filter and drain system for draining oil from an internal combustion engine having a sump for holding oil and oil filter attachment means associated with the engine, said system including adapter means coupled to the attachment means for enabling installation and operation of an oil filter at a remote point from the engine, drain means including a drain valve interconnected with the sump for draining the oil, the drain means including actuating means for enabling draining of the oil from the remote point without removal of the drain means, and interlock means precluding operation of the drain means when the oil filter is operatively associated with said adapter means, the interlock means comprising:
- a support frame located at the remote point for supporting the adapter means and the oil filter;
- control means operatively associated with said support frame having an interlock tab movable between a drain position and a safe position, said interlock tab when in the drain position occupying space normally occupied by the oil filter and when in said safe position occupying space remote from the oil filter in its operative position;
- and
- attaching means for securing said actuating means to said control means.
In an interlocked oil filter and drain system for draining oil from an internal combustion engine having a sump for holding oil and oil filter attachment means on the engine, adapter means coupled to the attachment means for enabling installation and operation of an oil filter at a remote point from the engine, drain means interconnected with said sump for draining the oil, the drain means including cable means for enabling draining of the oil from the remote point without removal of the drain means, and interlock means precluding operation of the drain means when the oil filter is installed, the interlock means comprising:
- a support frame located at the remote point for supporting the adapter means and an oil filter;
- a lever arm rotatably mounted on said support frame and having an axis of rotation between its ends, said axis of rotation transverse the oil filter;
- cable attaching means located at one end of said lever arm for securing said cable means to said lever arm;
- actuating means attached to the end of said lever arm opposite said axis of rotation and said cable attaching means for rotting said lever arm to operate the cable means;
- and
- an interlocking tab attached to the end of said lever arm opposite said actuating means, for engaging the outside cylindrical surface of the oil filter to impede the rotation of said lever arm when the oil filter is mounted to the adapter means.
