Abstract
A pipe nipple has a bore therethrough, with an entrance chamber at one end of the bore having a larger diameter adjacent a drive configuration of narrower diameter for receiving a tool therein to rotate the nipple about its longitudinal axis. The exterior of the nipple has a surface formation as a stop against which a hose can be inserted over the nipple, and a threaded length for attaching the nipple to another device.
Claims22
A method of manufacturing a pipe nipple for an automobile cooling system, comprising:
- cold-forming material into the shape of the nipple, said cold forming including steps of:
- creating a substantially cylindrical body having first and second ends and a bore therethrough;
- and
- shaping the bore at one of the ends to include an entrance chamber of relatively larger diameter and a drive configuration narrower in diameter than the entrance chamber, the drive configuration being between the entrance chamber and the other end and being shaped to receive a tool therein for rotating the nipple about a longitudinal axis of the nipple;
- and
- creating a thread along a portion of the body from the end thereof opposite the end having the entrance chamber.
A nipple comprising:
- a cylindrical body having an outer surface, first and second ends and a longitudinal bore there through;
- said first end having a helical thread thereon on the outside thereof,
- said second end having an outwardly extending enlargement and being configured to receive a hose thereover;
- and
- said bore configured at said second end with an entrance chamber of comparatively larger diameter and a drive configuration of comparatively narrower diameter, said drive configuration being shaped for receiving a tool therein for axially rotating said nipple, said drive configuration disposed inwardly from said entrance chamber relative to said second end.
A pipe nipple for an automobile cooling system, said nipple comprising:
- a cylindrical body having an outer surface, a first end having a thread adapted for engagement with threads of a cooling system component, a second end adapted to be received in a cooling system hose, and an axial bore extending there through;
- and
- said bore defining an entrance chamber at said second end and a drive configuration between said entrance chamber and said fust end, said drive configuration being shaped for receiving a tool therein for rotating said nipple about the axis thereof, and said entrance chamber being of larger diameter than said drive configuration.
A manufacturing system for making a pipe nipple for an automobile cooling system, comprising:
- means for cold-forming material into the shape of the nipple, said means for cold forming including:
- means for creating a substantially cylindrical body having first and second ends and a bore therethrough;
- and
- means for shaping the bore at one of the ends to include an entrance chamber of relatively larger diameter and a drive configuration narrower in diameter than the entrance chamber, the drive configuration being between the entrance chamber and the other end and being shaped to receive a tool therein for rotating the nipple about a longitudinal axis of the nipple;
- and
- means for creating a thread along a portion of the body from the end thereof opposite the end having the-entrance-chamber.
