Abstract
An irrigation fitting cooperable with a tool to penetrate the wall of an irrigation conduit comprising a body having a flow passage therein opening at a first location adjacent one end of the body and at a second location spaced from the first location. One end of the body is shaped to form a piercing point for penetrating the wall of the irrigation conduit. A shoulder is provided on the body intermediate the first and second locations and facing in a direction so that a tool can act against the shoulder to force the piercing point to penetrate the wall of the irrigation conduit. Orienting surfaces are provided on the body adjacent the shoulder for cooperating with the tool to orient the irrigation fitting relative to the tool.
Claims18
An irrigation fitting cooperable with an installation tool to penetrate the wall of an irrigation conduit, said irrigation fitting comprising:
- a body having a flow passage therein opening at a first location adjacent one end of the body;
- said one end of said body being shaped to form a piercing point for penetrating the wall of the irrigation conduit whereby said one end of said body can enter the irrigation conduit and the opening can communicate with the interior of the irrigation conduit;
- said flow passage opening at a second location spaced from said first location;
- a shoulder on said body intermediate said first and second locations so that the installation tool can be moved generally radially of the fitting over the shoulder to engage the shoulder to force the piercing point to penetrate the wall of the irrigation conduit;
- and
- orienting means on said body intermediate said shoulder and said second location and adjacent the shoulder for engaging the installation tool when the installation tool engages the shoulder to angularly orient the irrigation fitting relative to the installation tool.
An irrigation fitting cooperable with an installation tool to penetrate the wall of an irrigation conduit, said irrigation fitting comprising:
- a body having a flow passage therein opening at a first location adjacent one end of the body;
- said one end of said body being shaped to form a piercing point for penetrating the wall of the irrigation conduit whereby said one end of said body can enter the irrigation conduit and the opening can communicate with the interior of the irrigation conduit;
- said flow passage opening at a second location spaced from said first location;
- a shoulder on said body intermediate said first and second locations and facing in a direction so that the installation tool can act against the shoulder to force the piercing point to penetrate the wall of the irrigation conduit;
- orienting means on said body intermediate said first and second locations and adjacent the shoulder for cooperating with the installation tool to orient the irrigation fitting relative to the installation tool;
- a flange on said body, said shoulder being on said flange;
- an end portion of the body adjacent said one end forming a head and said body having a shank of lesser cross sectional area than said head and said shank joining the head to the flange;
- and
- said shoulder being generally U-shaped and having generally opposite legs and said orienting means including generally parallel surfaces extending from the legs of the shoulder.
An irrigation fitting cooperable with an installation tool to penetrate the wall of an irrigation conduit, said irrigation fitting comprising:
- a body having a flow passage therein opening at a first location adjacent one end of the body;
- said one end of said body being shaped to form a piercing point for penetrating the wall of the irrigation conduit whereby said one end of said body can enter the irrigation conduit and the opening can communicate with the interior of the irrigation conduit;
- said flow passage opening at a second location spaced from said first location;
- a shoulder on said body intermediate said first and second locations and facing in a direction so that the installation tool can act against the shoulder to force the piercing point to penetrate the wall of the irrigation conduit;
- and
- orienting means on said body intermediate said first and second locations and adjacent the shoulder for cooperating with the installation tool to angularly orient the irrigation fitting relative to the installation tool in only one predetermined angular position.
An irrigation fitting cooperable with an installation tool to penetrate the wall of an irrigation conduit, said irrigation fitting comprising:
- a body having a flow passage therein opening at a first location adjacent one end of the body;
- said one end of said body being shaped to form a piercing point for penetrating the wall of the irrigation conduit whereby said one end of said body can enter the irrigation conduit and the opening can communicate with the interior of the irrigation conduit;
- said flow passage opening at a second location spaced from said first location;
- a generally U-shaped shoulder on said body intermediate said first and second locations and facing in a direction so that the installation tool can act against the shoulder to force the piercing point to penetrate the wall of the irrigation conduit, said shoulder having generally opposite legs;
- and
- orienting means on said body intermediate said first and second locations and adjacent the shoulder for cooperating with the installation tool to angularly orient the irrigation fitting relative to the installation tool, said orienting means including generally parallel surfaces adjacent said legs, respectively.
An irrigation fitting cooperable with an installation tool to penetrate the wall of an irrigation conduit, said irrigation fitting comprising:
- a body having a flow passage therein opening at a first location adjacent one end of the body;
- said one end of said body being shaped to form a piercing point for penetrating the wall of the irrigation conduit whereby said one end of said body can enter the irrigation conduit and the opening can communicate with the interior of the irrigation conduit;
- said flow passage opening at a second location spaced from said first location;
- a shoulder on said body intermediate said first and second locations and facing in a direction so that the installation tool can act against the shoulder to force the piercing point to penetrate the wall of the irrigation conduit;
- orienting means on said body intermediate said first and second locations and adjacent the shoulder for cooperating with the installation tool to at least partially orient the irrigation fitting relative to the installation tool;
- and
- said body at said one end having a concave face at which the flow passage opens at said one location and a line between the opposite ends of the face as viewed in side elevation forms an acute angle with the axis of the flow passage.
