ABSTRACT:
A tool is shown for installing irrigation barb emitters in irrigation tubing. The tool comprises a cradle member and a barb holder member arranged in crossed relation and connected intermediate their ends at a pivot. The cradle member and the barb holder member have a cradle handle and a barb holder handle, respectively, extending rearwardly from the pivot. The cradle member and the barb holder member have a cradle jaw and a barb holder jaw, respectively, extending forwardly from the pivot. A cradle is mounted at the end of the cradle jaw which receives a peripheral portion of an irrigation tubing. A barb holder is mounted at the end of the barb holder jaw directly opposite the cradle. The barb holder is a hollow cylinder having an axis aligned with the cradle which releasably receives a barb emitter. A shoulder within the hollow cylinder acts against an annular disk shoulder on the barb emitter to force a piercing point on the barb emitter to penetrate the periphery of the irrigation tubing held within the cradle when the cradle jaw and the barb holder jaw are brought together.
