ABSTRACT:
A tool is provided for use in installing irrigation barb emitters in irrigation tubing. The tool comprises a cradle member having a cradle handle and a cradle jaw on opposing ends and a barb holder member having a barb holder handle and a barb holder jaw on opposing ends. The cradle member and the barb holder member are arranged in crossed relation. A cradle mounted on the cradle jaw is suitable for receiving a peripheral portion of an irrigation tubing. A barb holder mounted on the barb holder jaw is a hollow cylindrical cavity formed by two opposing barb holder jaw members. The barb holder has an axis aligned with the cradle with the opposing barb holder jaw members forming a slot opening therebetween. The slot opening is sized to allow snap fitting of the hollow cylinder of a barb emitter laterally into the hollow cylindrical cavity. A shoulder is formed by the lower edges of the opposing jaw members and acts against an annular disk shoulder on a barb emitter to force a piercing point on the barb emitter to penetrate irrigation tubing held within the cradle when the cradle jaw and the barb holder jaw are brought together. The barb emitter is released from the barb holder and retained within the irrigation tubing upon movement of the barb holder away from the cradle.
