Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
179 words
An air line oiler for use with an air line having an upstream portion and a downstream portion, said oiler comprising: an oil chamber, the ends of the air line portions being arranged within said chamber and spaced apart from each other, a capillary member within said chamber, said member completely covering the inlet end of the downstream portion of the air line, so that all the air entering said chamber through the upstream portion of said air line will flow across said capillary member into the downstream portion of the air line, and a nozzle extending through said capillary member, one end of said nozzle being open to said chamber interior and the other end being arranged within the downstream portion of the air line, said one end of said nozzle being spaced from the end of the upstream portion of the air line located within said chamber, so that a portion of the air entering the downstream portion of the air line flows through said capillary member and the remainder of the air flows through said nozzle.
Claim 2
Dependent Claim
179 words
An air line oiler for use with an air line having an upstream portion and a downstream portion, said oiler comprising: an oil chamber, the ends of the air line portions being arranged within said chamber and spaced apart from each other, a capillary member within said chamber, said member completely covering the inlet end of the downstream portion of the air line, so that all the air entering said chamber through the upstream portion of said air line will flow across said capillary member into the downstream portion of the air line, and a nozzle extending through said capillary member, one end of said nozzle being open to said chamber interior and the other end being arranged within the downstream portion of the air line, said one end of said nozzle being spaced from the end of the upstream portion of the air line located within said chamber, so that a portion of the air entering the downstream portion of the air line flows through said capillary member and the remainder of the air flows through said nozzle.
Claim 3
Dependent Claim
58 words
An air line oiler as defined in claim 1 wherein the spacing between said one end of said nozzle and the end of the upstream portion of the air line within said chamber is adjustable to vary the proportion between the amount of air flowing through said nozzle and the amount of air flowing through said capillary member.
Claim 4
Dependent Claim
24 words
An air line oiler as defined in claim 1 wherein the inlet end of the downstream portion of the air line is funnel shaped.
Claim 5
Dependent Claim
36 words
An air line oiler as defined in claim 1 including a bleed opening in the downstream portion of the air line establishing communication between the interior of said downstream portion and the interior of said chamber.
