Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
128 words
A method for remotely priming an oil pump in an engine comprising the steps of: a. exposing the oil filter mounting pad of the engine to reveal the oil inlet passage from the oil pump, the oil outlet passage to the engine''s lubricated parts and the oil chamber formed within said mounting pad; b. convering the oil chamber of said mounting pad for sealing that chamber and the oil inlet passage communicating therewith against leakage and for isolating the oil outlet passage therefrom; and c. applying a suction to said sealed oil chamber to cause oil to move from the oil sump of the engine through the oil pump, through the oil inlet passage and through the oil chamber so that any entrapped air will be purged therefrom.
Claim 2
Independent Claim
128 words
A method for remotely priming an oil pump in an engine comprising the steps of: a. exposing the oil filter mounting pad of the engine to reveal the oil inlet passage from the oil pump, the oil outlet passage to the engine''s lubricated parts and the oil chamber formed within said mounting pad; b. convering the oil chamber of said mounting pad for sealing that chamber and the oil inlet passage communicating therewith against leakage and for isolating the oil outlet passage therefrom; and c. applying a suction to said sealed oil chamber to cause oil to move from the oil sump of the engine through the oil pump, through the oil inlet passage and through the oil chamber so that any entrapped air will be purged therefrom.
Claim 3
Independent Claim
149 words
An apparatus for remotely priming the oil pump of an engine comprising: a. an engine having an oil filter mounting pad in which an oil chamber is formed, the oil chamber having an oil inlet passage leading thereto from the engine''s oil pump and having a hollow stud protruding therefrom through which an oil outlet passage leads to the engine''s lubricated parts; b. adapter means demountably attached to the oil filter mounting pad of said engine for sealing the oil chamber and the oil inlet passage against leakage and isolating the oil outlet passage therefrom; and c. suction means coupled to said adapter means and in communication with the sealed oil chamber of the filter mounting pad of said engine for causing oil to move from the engine''s oil sump through the oil pump, oil inlet line and into the sealed oil chamber for expulsion through said suction means.
Claim 4
Independent Claim
149 words
An apparatus for remotely priming the oil pump of an engine comprising: a. an engine having an oil filter mounting pad in which an oil chamber is formed, the oil chamber having an oil inlet passage leading thereto from the engine''s oil pump and having a hollow stud protruding therefrom through which an oil outlet passage leads to the engine''s lubricated parts; b. adapter means demountably attached to the oil filter mounting pad of said engine for sealing the oil chamber and the oil inlet passage against leakage and isolating the oil outlet passage therefrom; and c. suction means coupled to said adapter means and in communication with the sealed oil chamber of the filter mounting pad of said engine for causing oil to move from the engine''s oil sump through the oil pump, oil inlet line and into the sealed oil chamber for expulsion through said suction means.
Claim 5
Dependent Claim
116 words
An apparatus as claimed in claim 2 wherein said adapter means comprises: a. a plate having an aperture formed therethrough for receiving the stud of the filter mounting pad of said engine, said plate having a passage formed therethrough to which said suction means is coupled; b. gasket mens affixed to one surface of said plate for forming a seal between said plate and the filter mounting pad of said engine; and c. a mounting nut within the aperture formed in said plate and in threaded engagement with the stud of the filter mounting pad of said engine, said mounting nut adapted to sealingly demountably attach said plate to the filter mounting pad of said engine.
Claim 6
Dependent Claim
77 words
An apparatus as claimed in claim 3 wherein said mounting nut comprises: a. a head having means thereon by which said head may be gripped for axial rotation; and b. at least one internally threaded boss integral with said head and axially extending therefrom, said boss having a circumference which is smaller than the peripheral dimension of said head to form a radially extending shoulder between the periphery of said boss and the periphery of said head.
Claim 7
Dependent Claim
52 words
An apparatus as claimed in claim 2 wherein said suction Means is an air gun having means thereon for creating a low pressure with respect to atmospheric pressure and coupling that low pressure to said adapter means for transmission therethrough into the oil chamber of the filter mounting pad of said engine.
Claim 8
Dependent Claim
140 words
An apparatus as claimed in claim 2 wherein said suction means comprises: a. a source of air under pressure; b. an air gun having a barrel thereon, the barrel having a bore formed therethrough, said gun coupled to receive air under pressure from said source and direct that air through the bore of the barrel; c. a nozzle mounted on the barrel of said air gun and having an orifice formed therein which is coaxial with the bore of the barrel, the orifice having a smaller diameter than the bore of the barrel, said nozzle having a low pressure chamber downstream of the orifice; and d. means on said nozzle and in communication with the low pressure chamber thereof for coupling the low pressure chamber of said nozzle to the oil chamber of the filter mounting pad of said engine.
Claim 9
Independent Claim
182 words
An apparatus for remotely priming the oil pump of an engine of the type having an oil filter mounting pad in which an oil chamber is formed for receiving oil from the engine''s oil pump and from which oil is supplied to the engine''s lubricated parts through an externally threaded hollow stud protruding from the oil chamber of the mounting pad, said apparatus comprising a plate engagable with the mounting pad of the engine, said plate having an aperture formed therethrough for receiving the stud of the engine''s mounting pad, a mounting nut positionable within the aperture of said plate and threadably engagable with the stud of the engine''s mounting pad for sealingly demountably attaching said plate to the engine''s mounting pad and for blocking the hollow stud of the engine''s mounting pad, and suction means coonnected to said plate and in communication with the oil chamber of the engine''s mounting pad for causing oil to move from the engine''s oil sump, through the engine''s oil pump, into the oil chamber of the engine''s mounting pad for expulsion through said suction means.
Claim 10
Independent Claim
182 words
An apparatus for remotely priming the oil pump of an engine of the type having an oil filter mounting pad in which an oil chamber is formed for receiving oil from the engine''s oil pump and from which oil is supplied to the engine''s lubricated parts through an externally threaded hollow stud protruding from the oil chamber of the mounting pad, said apparatus comprising a plate engagable with the mounting pad of the engine, said plate having an aperture formed therethrough for receiving the stud of the engine''s mounting pad, a mounting nut positionable within the aperture of said plate and threadably engagable with the stud of the engine''s mounting pad for sealingly demountably attaching said plate to the engine''s mounting pad and for blocking the hollow stud of the engine''s mounting pad, and suction means coonnected to said plate and in communication with the oil chamber of the engine''s mounting pad for causing oil to move from the engine''s oil sump, through the engine''s oil pump, into the oil chamber of the engine''s mounting pad for expulsion through said suction means.
