Abstract
Abstract A bearing lubricator constituted by a tubular element providing a lubricant receiving chamber adjacent one extremity thereof, said chamber having an open mouth for the reception and secure retention of an outwardly projecting lubricating fitting, the remainder of said tubular element being arcuately flattened to provide an angularly offset and gradually tapered portion terminating in an arcuate discharge orifice at the extremity remote from the lubricating fitting, the cross-sectional relationship between the lubricant receiving chamber and the discharge orifice being on the order of 10:1.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
103 words
A bearing lubricator comprising a tubular element having a hand-hold portion at the outer extremity thereof, an intermediate inwardly tapered portion, and an elongated and angularly offset restricted passageway extending inwardly from the opposite extremity of said tubular element and communicating with said inwardly tapered portion, said restricted passageway terminating in a narrow elongate arcuately curved discharge orifice; a lubricant receiving chamber having an open mouth extending inwardly through said hand-hold portion to said intermediate inwardly tapered portion and communicating therewith; and an outwardly projecting lubricating fitting securely mounted within said open mouth in sealed relationship with respect to said lubricant receiving chamber.
Claim 2
Dependent Claim
103 words
A bearing lubricator comprising a tubular element having a hand-hold portion at the outer extremity thereof, an intermediate inwardly tapered portion, and an elongated and angularly offset restricted passageway extending inwardly from the opposite extremity of said tubular element and communicating with said inwardly tapered portion, said restricted passageway terminating in a narrow elongate arcuately curved discharge orifice; a lubricant receiving chamber having an open mouth extending inwardly through said hand-hold portion to said intermediate inwardly tapered portion and communicating therewith; and an outwardly projecting lubricating fitting securely mounted within said open mouth in sealed relationship with respect to said lubricant receiving chamber.
Claim 3
Dependent Claim
31 words
A bearing lubricator as set forth in claim 1 where the longitudinal axis of said angularly offset restricted passageway varies on the order of 15° from that of said hand-hold portion.
Claim 4
Dependent Claim
31 words
A bearing lubricator as set forth in claim 1 where the cross-sectional area of said arcuate discharge orifice is on the order of 10% of that of said lubricant receiving chamber.
Claim 5
Dependent Claim
31 words
A bearing lubricator as set forth in claim 1 where the length of said elongated restricted passageway is on the order of 65% of the entire length of said tubular element.
Claim 6
Dependent Claim
58 words
A bearing lubricator as set forth in claim 1 where a plug having a threaded bore extending therethrough is mounted within the open mouth of said lubricant receiving chamber, the peripheral edge of said tubular element being rolled inwardly to retain said plug in sealed relationship, and said lubricating fitting is threaded into the bore of said plug.
Claim 7
Dependent Claim
74 words
A bearing lubricator as set forth in claim 5 where the longitudinal axis of said angularly offset restricted passageway varies on the order of 15% from that of said hand-hold portion, where the height of said discharge orifice is on the order of 10% of the diameter of said lubricating chamber, and where the length of said elongated restricted passageway is on the order of 65% of the entire length of said tubular element.
Claim 8
Independent Claim
128 words
The method of producing a bearing lubricator which includes the steps of taking a length of tubular material having an open mouth at each extremity thereof, mounting an outwardly extending lubricating fitting in one extremity of said tubular material in sealed relationship with respect to the interior thereof, compressing said tubular material concavely for substantially 65% of the length thereof commencing from the extremity remote from said lubricating fitting to provide an arcuate discharge orifice restricted to on the order of 10% of the original diameter thereof, and producing an angularly offset restricted passageway within said tubular material extending inwardly from said discharge orifice, the longitudinal axis of said restricted passageway varying on the order of 15% from the longitudinal axis of the remainder of said tubular material.
Claim 9
Independent Claim
128 words
The method of producing a bearing lubricator which includes the steps of taking a length of tubular material having an open mouth at each extremity thereof, mounting an outwardly extending lubricating fitting in one extremity of said tubular material in sealed relationship with respect to the interior thereof, compressing said tubular material concavely for substantially 65% of the length thereof commencing from the extremity remote from said lubricating fitting to provide an arcuate discharge orifice restricted to on the order of 10% of the original diameter thereof, and producing an angularly offset restricted passageway within said tubular material extending inwardly from said discharge orifice, the longitudinal axis of said restricted passageway varying on the order of 15% from the longitudinal axis of the remainder of said tubular material.
