Abstract
Abstract A hose connector having a tubular body has improved barb means thereon for retaining a hose on the body of the connector. The barb means comprises a plurality of small barbs arranged in dual tapering sets. The first set of barbs increases in size from an end of the tubular body to an intermediate portion thereof at one mean slope, and the second set of barbs increases in size, moving from the intermediate portion toward the opposite end of the body, at a larger mean slope. The barbs provide a very tight interference fit with the hose, but yet permit the hose to be manually installed on the body of the connector.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
130 words
In a hose connector having an elongated tubular body, one end thereof forming a stem portion adapted to receive a hose and the other end thereof having a coupling portion adapted to be connected to a fluid conduit, the improvement comprising a plurality of annular barb means on said tubular body, said barb means first increasing, then decreasing and then increasing in external radial dimensions from the stem portion toward the coupling portion, the rates of increase in external radial dimensions of said barb means being different, said barb means including first and second sets of at least two barbs each, the last barb of the second set being of the largest external radial dimension and the first barb of the first set being of the smallest external radial dimension.
Claim 2
Dependent Claim
130 words
In a hose connector having an elongated tubular body, one end thereof forming a stem portion adapted to receive a hose and the other end thereof having a coupling portion adapted to be connected to a fluid conduit, the improvement comprising a plurality of annular barb means on said tubular body, said barb means first increasing, then decreasing and then increasing in external radial dimensions from the stem portion toward the coupling portion, the rates of increase in external radial dimensions of said barb means being different, said barb means including first and second sets of at least two barbs each, the last barb of the second set being of the largest external radial dimension and the first barb of the first set being of the smallest external radial dimension.
Claim 3
Dependent Claim
58 words
In a hose connector as in claim 1, wherein said barb means includes seven barbs, the first four barbs of the first set and the last three barbs of the second set increase in external radial dimension from said stem portion toward said coupling portion, the fifth barb being of smaller external radial dimension than either adjacent barb.
Claim 4
Dependent Claim
58 words
In a hose connector as in claim 1, wherein said barb means includes seven barbs, the first five barbs of the first set and the last two barbs of the second set increase in external radial dimension from said stem portion toward said coupling portion, the sixth barb being of smaller external radial dimension than either adjacent barb.
