Abstract
Abstract An auxiliary lubrication means is disclosed which is suitable for use in conjunction with an internal combustion engine or similar mechanical device. The present apparatus includes a reservoir for storing a lubricant under pressure during normal operation of the engine. Upon failure of the engine's lubrication system, or during a subsequent start-up procedure, the means of the present invention is operative to provide lubricant to the moving parts of the engine.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
158 words
A device, interposed within the primary lubrication system of an internal combustion engine for providing lubricant under pressure to the engine during pre-start or failure of the primary lubrication system; the primary lubrication system including a lubricant under pressure during operation of the engine, a lubricant filter and means for mounting the filter on the engine; comprising: an adaption plate interposed between said filter and said means for mounting said filter; a first reservoir for storing a lubricant under pressure and maintaining said lubricant under pressure; directing means within said adaptor plate, for diverting a first portion of said lubricant flowing through said primary lubrication system; first fluid communication means for communicating said first portion of said lubricant from said diverting means to said first reservoir; first releasing means for releasing said lubricant stored in said first reservoir into said primary lubrication system through said first fluid communication means; and first control means for controlling said releasing means.
Claim 2
Independent Claim
158 words
A device, interposed within the primary lubrication system of an internal combustion engine for providing lubricant under pressure to the engine during pre-start or failure of the primary lubrication system; the primary lubrication system including a lubricant under pressure during operation of the engine, a lubricant filter and means for mounting the filter on the engine; comprising: an adaption plate interposed between said filter and said means for mounting said filter; a first reservoir for storing a lubricant under pressure and maintaining said lubricant under pressure; directing means within said adaptor plate, for diverting a first portion of said lubricant flowing through said primary lubrication system; first fluid communication means for communicating said first portion of said lubricant from said diverting means to said first reservoir; first releasing means for releasing said lubricant stored in said first reservoir into said primary lubrication system through said first fluid communication means; and first control means for controlling said releasing means.
Claim 3
Dependent Claim
39 words
A device, as recited in claim 1, wherein said adaptor plate comprises: a first portion adapted to be operatively connected to said means for mounting said filter to said engine; and a second portion adapted for mounting said filter.
Claim 4
Dependent Claim
37 words
A device, as recited in claim 2, wherein said first control means comprises: means for sensing a signal indicating that said primary lubrication system is inoperative; and means for communicating said signal to said first releasing means.
Claim 5
Dependent Claim
19 words
A device, as recited in claim 3, wherein said signal is generated in an oil pressure warning light circuit.
Claim 6
Dependent Claim
80 words
A device, as recited in claim 4; wherein said directing means diverts a second portion of said lubricant; and wherein said device further comprises: a second reservoir; second fluid communication means for communicating said second portion of said lubricant from said diverting means to said second reservoir; second releasing means for releasing said lubricant stored in said second reservoir into said primary lubrication system through said second fluid communication means; and second control means for controlling said second releasing means.
Claim 7
Dependent Claim
31 words
A device, as recited in claim 5, wherein said second control means comprises: means for communicating said signal indicating that said primary lubrication system is inoperative to said second releasing means.
Claim 8
Dependent Claim
35 words
A device, as recited in claim 5, wherein said second control means comprises: a manually operated switch for producing an operator generated signal means for communicating said operator generated signal to said second releasing means.
