Abstract
Abstract A method and apparatus are disclosed for greasing an article such as a wheel bearing in a common vice including a housing defining an internal grease chamber including a first open end; a dished piston slidably insertable into said chamber, including a threaded aperture; a stem threadably mounted in the piston aperture; and a tapered spool compression application member disposed over the stem for forcing the piston against the grease to cause grease to pass through the piston and into the bearing.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
96 words
A method of applying a lubricant to a bearing comprising inserting said bearing into a lubricant chamber to seal an outer peripheral surface of said bearing against a tapered surface of a piston member disposed within said lubricant chamber; sealing an inner peripheral surface of said bearing with tapered spool member by inserting said tapered spool member within a central aperture in said bearing; mounting said lubricant chamber between vice jaws of a common vice; and compressing said vice jaws to force grease through a central opening in said piston member and outwardly into said bearing.
Claim 2
Independent Claim
96 words
A method of applying a lubricant to a bearing comprising inserting said bearing into a lubricant chamber to seal an outer peripheral surface of said bearing against a tapered surface of a piston member disposed within said lubricant chamber; sealing an inner peripheral surface of said bearing with tapered spool member by inserting said tapered spool member within a central aperture in said bearing; mounting said lubricant chamber between vice jaws of a common vice; and compressing said vice jaws to force grease through a central opening in said piston member and outwardly into said bearing.
Claim 3
Independent Claim
97 words
A method of applying a lubricant to a bearing comprising inserting said bearing into a lubricant chamber to seal an outer peripheral surface of said bearing against a frusto-conical surface of a piston member disposed within said lubricant chamber; sealing an inner peripheral surface of said bearing by engaging said inner peripheral surface against a tapered spool member; compressing said spool member against said bearing to force said piston against a lubricant held in said chamber so that said lubricant is forced upwardly into a lubricant receiving aperture in said piston and into contact with said bearing.
Claim 4
Independent Claim
97 words
A method of applying a lubricant to a bearing comprising inserting said bearing into a lubricant chamber to seal an outer peripheral surface of said bearing against a frusto-conical surface of a piston member disposed within said lubricant chamber; sealing an inner peripheral surface of said bearing by engaging said inner peripheral surface against a tapered spool member; compressing said spool member against said bearing to force said piston against a lubricant held in said chamber so that said lubricant is forced upwardly into a lubricant receiving aperture in said piston and into contact with said bearing.
