Trickle irrigation system

Claim 2

A trickle irrigation system comprising in combination, two pieces of tubing and an in line trickler of substantially the same size as said tubes affixed therebetween, said trickler having a generally cylindrical male member with a friction fir coupling member on one end for engaging the inner wall of one piece of the tubing to frictionally hold it therein in a fluid tight connection, said male member defining by helical ridges extending therefrom on the outer periphery, a longitudinal central aperture therethrough in which fluid may flow from said tubing, a generally hollow cylindrical mating female member with a smooth interior surface adapted to rest on said ridges and thereby establish a water flow path through the helical path formed by said ridges and further including structure to receive and hold said male member therein at one end and having at the other end a friction fit coupling member to engage the inner wall of the other piece of tubing to frictionally hold it therein in a fluid tight connection and defining a longitudinal aperture therethrough mating with that of the male member so that fluid will flow through said trickler from one tube to the other, and wherein said male and female members have structure disposed therebetween when mated for defining a passageway permitting a portion of the fluid flowing through said tubes to trickle out between the two members comprising, a feeding chamber insuring the continuous flow of water between the two members formed by structure on the butt end of said male member forming a cavity for receiving fluid passing through said tubes and directing it into said helical ridges wherein said ridges have a longitudinal regulating duct disposed therethrough over a portion of said ridges to define a water conveying passageway bypassing said helical path.

Claim 3

A trickle irrigation system comprising in combination, two pieces of tubing and an in line trickler of substantially the same size as said tubes affixed therebetween, said trickler having a generally cylindrical male member with a friction fit coupling member on one end for engaging the inner wall of one piece of the tubing to frictionally hold it therein in a fluid tight connection, said male member defining by helical ridges extending therefrom on the outer periphery, a longitudinal central aperture therethrough in which fluid may flow from said tubing, a generally hollow cylindrical mating female member with a smooth interior surface adapted to rest on said ridges and thereby establish a water flow path through the helical path formed by said ridges and further including structure to receive and hold said male member therein at one end and having at the other end a friction fit coupling member to engage the inner wall of the other piece of tubing to frictionally hold it therein in a fluid tight connection and defining a longitudinal aperture therethrough mating with that of the male member so that fluid will flow through said trickler from one tube to the other, and wherein said male and female members have structure disposed therebetween when mated for defining a passageway permitting a portion of the fluid flowing through said tubes to trickle out between the two members comprising, a feeding chamber insuring the continuous flow of water between the two members formed by structure on the butt end of said male member forming a cavity for receiving fluid passing through said tubes and directing it into said helical ridges wherein said female member has therein longitudinally disposed strias for contacting with the end of the male member when mated therein to feed fluid flowing through said tubes into the feeding chamber between the members, and wherein said strias have a smaller dimension than said passageway to thereby prevent entry of particles of a size that could block said passageway.

Claim 4

A trickle irrigation system comprising in combination, two pieces of tubing and an in line trickler of substantially the same size as said tubes affixed therebetween, said trickler having a generally cylindrical male member with a friction fit coupling member on one end for engaging the inner wall of one piece of the tubing to frictionally hold it therein in a fluid tight connection, said male member defining by helical ridges extending therefrom on the outer periphery, a longitudinal central aperture therethrough in which fluid may flow from said tubing, a generally hollow cylindrical mating female member with a smooth interior surface adapted to rest on said ridges and thereby establish a water flow path through the helical path formed by said ridges and further including structure to receive and hold said male member therein at one end and having at the other end a friction fit coupling member to engage the inner wall of the other piece of tubing to frictionally hold it therein in a fluid tight connection and defining a longitudinal aperture therethrough mating with that of the male member so that fluid will flow through said trickler from one tube to the other, and wherein said male and female members have structure disposed therebetween when mated for defining a passageway permitting a portion of the fluid flowing through said tubes to trickle out between the two members comprising, a feeding chamber insuring the continuous flow of water between the two members formed by structure on the butt end of said male member forming a cavity for receiving fluid passing through said tubes and directing it into said helical ridges wherein said female member has therein longitudinally disposed strias for contacting with the end of the male member when mated therein to feed fluid flowing through said tubes into the feeding chamber between the members, and wherein said strias have a smaller dimension than said passageway to thereby prevent entry of particles of a size that could block said passageway.
