Abstract
Abstract A lubricational tool for internal combustion engines and the like comprises a body member, a shaft rotatably extended through the body member, with the shaft terminating in a slip joint for engagement with an oil pump within the engine. The body member is shaped for extension thereof together with the shaft through an opening in a block of the engine. An arrangement is provided for rotating the shaft in engagement with the oil pump for lubricating the engine prior to start-up.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
107 words
In an internal combustion engine having an internal lubricant pump coupled to said engine for operation thereby, the improvement comprising a lubricational tool insertable into said engine for operating said pump to lubricate said engine prior to engine start-up, said tool including a body member, a shaft rotatably extended through said body member, said shaft terminating in a slip-joint for engagement within said engine with said pump, said body member being shaped for extension of said shaft spacedly through an opening in a block of said engine, and means for rotating said shaft in operative engagement with said pump to lubricate said engine prior to said start-up.
Claim 2
Dependent Claim
107 words
In an internal combustion engine having an internal lubricant pump coupled to said engine for operation thereby, the improvement comprising a lubricational tool insertable into said engine for operating said pump to lubricate said engine prior to engine start-up, said tool including a body member, a shaft rotatably extended through said body member, said shaft terminating in a slip-joint for engagement within said engine with said pump, said body member being shaped for extension of said shaft spacedly through an opening in a block of said engine, and means for rotating said shaft in operative engagement with said pump to lubricate said engine prior to said start-up.
Claim 3
Dependent Claim
29 words
The combination according to claim 1 wherein said shaft is extended sufficiently outwardly of said body member for engagement with a portable power drill, torque wrench or the like.
Claim 4
Dependent Claim
24 words
The combination according to claim 1 wherein said body member is provided with a flange or collar member for closing said engine block opening.
Claim 5
Dependent Claim
34 words
The combination according to claim 3 wherein said collar member is removably mounted on said body member and replacement collar members of differing shapes are provided for closing correspondingly differently shaped engine block openings.
Claim 6
Dependent Claim
22 words
The combination according to claim 3 wherein said flange or collar is engagebly shaped with distributor holddown means provided on said engine.
Claim 7
Dependent Claim
42 words
The combination according to claim 1 wherein said slip-joint includes a connector-assembly adjacent an inward end of the shaft, said connector assembly including an axially projecting keying member and a sleeve member slidably mounted on the connectoR assembly adjacent said keying member.
Claim 8
Dependent Claim
35 words
The combination according to claim 6 wherein said sleeve is movable to a first position for engagement with an adjacent outer periphery of the shaft of said pump and to a second position withdrawn therefrom.
Claim 9
Dependent Claim
28 words
The combination according to claim 1 wherein said body member is provided with bearing means adjacent each end thereof, said shaft being rotatably mounted within said bearing means.
Claim 10
Dependent Claim
35 words
The combination according to claim 1 wherein said body member is provided with an extension thereof shaped for insertion through said engine block opening to maintain the spaced relation of said shaft in said opening.
Claim 11
Dependent Claim
124 words
In an internal combustion engine having an internal lubricant pump, the improvement comprising a lubricational tool to engage with said pump to lubricate said engine prior to start up, said tool including a body member, a shaft rotatably extended through said body member, said shaft terminating in a slip-joint for engagement within said engine with said pump, said body member being shaped for extension of said shaft spacedly through an opening in a block of said engine, and means for rotating said shaft in engagement with said pump to lubricate said engine prior to start up, said engine block opening being a distributor housing opening, said body member being provided with mounting means, said mounting means being shaped to close said distributor housing opening.
Claim 12
Dependent Claim
124 words
In an internal combustion engine having an internal lubricant pump, the improvement comprising a lubricational tool to engage with said pump to lubricate said engine prior to start up, said tool including a body member, a shaft rotatably extended through said body member, said shaft terminating in a slip-joint for engagement within said engine with said pump, said body member being shaped for extension of said shaft spacedly through an opening in a block of said engine, and means for rotating said shaft in engagement with said pump to lubricate said engine prior to start up, said engine block opening being a distributor housing opening, said body member being provided with mounting means, said mounting means being shaped to close said distributor housing opening.
Claim 13
Dependent Claim
49 words
The combination according to claim 10 wherein said shaft includes a detachable shaft extension positioned inwardly of said body member and a connector assembly detachably joined to the inward end of said shaft extension, and means coupled to said connector assembly for slip-engaging an input shaft of said pump.
Claim 14
Independent Claim
82 words
A method for lubricating an internal combustion engine prior to starting the engine, said method comprising the steps of inserting a shaft arrangement through an opening in an engine block of said engine, detachably joining said shaft to an input shaft of an internal lubricant pump of said engine, bypassing a cam shaft of said engine with said shaft arrangement, and rotating said shaft arrangement and said oil pump for a time sufficient to supply engine lubricant to the lubricant passages thereof.
Claim 15
Independent Claim
82 words
A method for lubricating an internal combustion engine prior to starting the engine, said method comprising the steps of inserting a shaft arrangement through an opening in an engine block of said engine, detachably joining said shaft to an input shaft of an internal lubricant pump of said engine, bypassing a cam shaft of said engine with said shaft arrangement, and rotating said shaft arrangement and said oil pump for a time sufficient to supply engine lubricant to the lubricant passages thereof.
Claim 16
Dependent Claim
24 words
