Abstract

A distribution fitting primarily useful in connection with drip or seep irrigation can be constructed so as to utilize a series of ports defined by circular holes located immediately adjacent to one another around a spherical wall, each of the ports being constructed so to serve as a compression fitting.

Claims

1. In an injection molded distribution fitting having a plurality of outlet port means for forming a compression joint for receiving a distribution tube, each of said port means being adapted to be connected to a distribution line the improvement which comprises:

said fitting having a spherical peripheral wall, said spherical wall having both a spherical interior and a spherical exterior, said port means being located in said wall, said wall having a uniform thickness adjacent to each of said port means.

each of said port means is defined by a circular hole located in said peripheral wall, each such hole being located so that an imaginary line extending perpendicular to its center will intersect the center of said peripheral wall and

each of said port means being shaped so as to include a beveled exterior surface leading to an edge, said edge surrounding and defining said circular hole,

a tube located within each of said ports so as to be held therein under compression.

2. A distribution fitting as claimed in claim 1 wherein:

said port means are located immediately adjacent to one another in a row extending around the center of said peripheral wall, and

said spherical wall is shaped as a truncated portion of a sphere and has a flat top.

3. A distribution fitting as claimed in claim 1 wherein:

said fitting includes a separate internal flow passage leading to each of said ports,

distributing means for distributing a fluid to each of said passages.

4. In an injection molded distribution fitting having a plurality of outlet port means for forming a compression joint for receiving a distribution tube, each of said port means being adapted to be connected to a distribution line the improvement which comprises:

said fitting having a peripheral wall, said wall having both a spherical exterior and a flat interior adjacent to each of said port means, said port means being located in said wall, said wall having a uniform thickness adjacent to each of said port means.

each of said port means is defined by a circular hole located in said peripheral wall, each such hole being located so that an imaginary line extending perpendicular to its center will intersect the center of said peripheral wall and

each of said port means being shaped so as to include a beveled exterior surface leading to an edge, said edge surrounding and defining said circular hole,

a tube located within each of said ports so as to be held therein under compression.

5. A distribution fitting as claimed in claim 4 wherein:

said port means are located immediately adjacent to one another in a row extending around the center of said peripheral wall, and

said spherical wall is shaped as a truncated portion of a sphere and has a flat top.

6. In an injection molded distribution fitting having a plurality of outlet ports, each of said ports being adapated to be connected to a distribution line the improvement which comprises:

said fitting having a peripheral wall, said wall having both a spherical interior and a spherical exterior, said ports being located in said wall, said wall having a uniform thickness adjacent to each of said ports,

each of said ports is defined by a circular hole located in said peripheral wall, each such hole being located so that an imaginary line extending perpendicular to its center will intersect the center of said peripheral wall and

each of said ports being shaped so as to include a beveled exterior surface leading to an edge, said edge surrounding and defining said circular hole, and

a tube means located within each of said ports so as to be held therein under compression.

7. A distribution fitting as claimed in claim 6 wherein:

said ports are located immediately adjacent to one another in a row extending around the center of said peripheral wall, and

said spherical wall is shaped as a truncated portion of a sphere and has a flat top.

8. In an injection molded distribution fitting having a plurality of outlet ports, each of said ports being adapted to be connected to a distribution line the improvement which comprises:

said fitting having a peripheral wall, said wall having both a spherical interior and a flat interior adjacent to each of said ports, said ports being located in said wall, said wall having a uniform thickness adjacent to each of said ports,

each of said ports is defined by a circular hole located in said peripheral wall, each such hole being located so that an imaginary line extending perpendicular to its center will intersect the center of said peripheral wall and

each of said ports being shaped so as to include a beveled exterior surface leading to an edge, said edge surrounding and defining said circular hole, and

a tube means located within each of said ports so as to be held therein under compression.

9. A distribution fitting as claimed in claim 8 wherein:

said ports are located immediately adjacent to one another in a row extending around the center of said peripheral wall, and

said spherical wall is shaped as a truncated portion of a sphere and has a flat top.
