Abstract:
1. An irrigation tool for inserting and removing irrigation emitter barbs from tubing, the irrigation tool comprising: a punch handle and a cradle handle, each handle having a cylindrical shape, the punch handle being slidably and telescopically received within the cradle handle, the cradle handle having a cylinder receiving cavity at one end thereof into which the punch handle extends and a crescent jaw having a seat adapted to support irrigation tubing at the other end, the crescent jaw mounted on the cradle handle opposite the punch handle, the punch handle having a cylindrical cavity positioned proximate to the cradle handle, the cylindrical cavity having a closed threaded punch end and an open end adjacent the cradle handle, a punch pin extending into the cylindrical cavity thereby partially occluding the open end, the punch pin having a first position extending into the crescent jaw when the punch handle is fully slidably received within the cradle handle, the punch pin having a second position which does not extending into the crescent jaw when the punch handle is not received fully within the cradle handle, the punch pin being biased to the second position, whereby irrigation tubing held within the crescent jaw is punctured when the punch pin is moved from the second position to the first position, at least one barb holder mounted on the punch handle, the barb holder comprising a lower cavity, a middle cavity, and an upper cavity concentrically oriented and cylindrically shaped with the upper cavity being of smaller diameter than the middle cavity thereby forming an upper shoulder therebetween and the middle cavity being a smaller diameter than the lower cavity thereby forming a lower shoulder therebetween, a plurality of resilient flaps extending inwardly from the periphery of the lower cavity, the upper shoulder within the hollow cylinder being suitable for acting against an annular disk shoulder on a barb emitter to force a piercing point on the barb emitter to penetrate a periphery of an irrigation tubing when forced therein, the plurality of flaps releasably holding the barb emitter within the barb holder; and a barb remover including a lower crescent gap and an upper crescent gap positioned at the distal ends of the crescent jaw, the crescent gaps being in parallel alignment, the crescent gaps being adapted to engage shoulder disks of emitter barbs to pry the emitter barbs from irrigation tubing.
