Abstract A bench top bearing packer tool includes supply means for delivering a controlled amount of grease, support means for locating a bearing in a position where a bearing cage and rollers of the bearing may be lubricated with the grease delivered by the supply means, the supply means having a grease delivery outlet communicating with a grease livery inlet of the support means by a grease flow passageway, and a means for controlling the passage of grease through the inlet to the bearing cage and rollers of the bearing. ## Claims ### Claim 1 A bearing lubrication tool comprising: a) supply means for delivering a controlled amount of grease, the supply means including a detachable grease cartridge and air cylinder assembly located remotely of the support means, the grease cartridge being installed in the air cylinder and adapted to be emptied of grease when a supply of compressed air displaces a piston in the cylinder that moves the grease to the grease delivery inlet of the support means, b) support means mounted on top of a work bench for locating a bearing in a position where a bearing cage and rollers of the bearing may be lubricated with the grease delivered by the supply means, the supply means having a grease delivery outlet communicating with a grease delivery inlet of the support means by a grease flow passageway, and c) means for controlling the passage of grease through the inlet to the bearing cage and rollers of the bearing, the means for controlling including a valve assembly comprising a cup and a retainer, wherein relative movement between the cup and the retainer causes the valve assembly to assume an open condition for allowing grease to pass through the inlet to the bearing cage and rollers of the bearing. ### Claim 2 (depends on 1) The bearing lubrication tool of claim 1 wherein the cup supports the bearing and moves downwardly relative to the retainer by downward pressure exerted on the bearing. ### Claim 3 (depends on 2) The bearing lubrication tool of claim 2 wherein the downward pressure exerted on the bearing is applied through a downwardly pointing cone that is supported on the bearing and which is pressed downwardly by manual application of force on a handle device. ### Claim 4 (depends on 3) The bearing lubrication tool of claim 3 wherein the cone includes means for centering the position of the handle device relative to the cone. ### Claim 5 (depends on 4) The bearing lubrication tool of claim 4 wherein the centering means of the cone comprises an upwardly extending member which engages a downwardly extending member of the handle device. ### Claim 6 (depends on 5) The bearing lubrication tool of claim 5 wherein the upwardly extending member includes a female portion that engages a male portion of the downwardly extending member. ### Claim 7 (depends on 3) The bearing lubrication tool of claim 3 wherein the handle device includes a cover portion for covering the valve assembly when the bearing is not located in a position where it may be lubricated. ### Claim 8 (depends on 7) The bearing lubrication tool of claim 7 wherein the cover portion is made of a clear plastic to allow viewing of the passage of grease to the bearing. ### Claim 9 (depends on 1) The bearing lubrication tool of claim 1 wherein the grease delivery inlet is a detachable coupling to the support means or a grease supply port of the support means. ### Claim 10 (depends on 1) The bearing lubrication tool of claim 1 wherein the cup is supported by spring means and moves downwardly relative to the retainer against upward pressure exerted by the spring means. ### Claim 11 (depends on 10) The bearing lubrication tool of claim 10 wherein the spring means comprise coil springs that press upwardly against an annular seat of the cup, the annular seat having a central opening which, in the absence of downward pressure exerted on the bearing when supported by the cup, is sealed by the retainer so as to prevent passage of grease through the opening. ### Claim 12 (depends on 11) The bearing lubrication tool of claim 11 wherein the retainer is secured in a fixed position through the central opening, and includes a cradle adapted to engage a leading portion of the cone when the bearing is not located in a position where it may be lubricated. ### Claim 13 A bearing lubrication tool comprising: a) supply means for delivering a controlled amount of grease, the supply means including a powered grease storage drum located remotely of the support means, the powered grease storage drum adapted to be emptied of grease when a supply of compressed air moves the grease to the grease delivery inlet of the support means, b) support means mounted on top of a work bench for locating a bearing in a position where a bearing cage and rollers of the bearing may be lubricated with the grease delivered by the supply means, the supply means having a grease delivery outlet communicating with a grease delivery inlet of the support means by a grease flow passageway, and c) means for controlling the passage of grease through the inlet to the bearing cage and rollers of the bearing, the means for controlling including a valve assembly comprising a cup and a retainer, wherein relative movement between the cup and the retainer causes the valve assembly to assume an open condition for allowing grease to pass through the inlet to the bearing cage and rollers of the bearing. ### Claim 14 (depends on 13) The bearing lubrication tool of claim 13 wherein the supply of compressed air is controlled by an air pressure regulator to allow the grease to flow at a regulated rate and be delivered in a controlled amount to the grease delivery inlet of the support means. ### Claim 15 (depends on 14) The bearing lubrication tool of claim 14 wherein the air pressure regulator maintains a constant air pressure and grease is caused to flow when the valve assembly assumes an open position.
