Abstract: A coupling comprises a sleeve shaped member (5) which has an external toothing (11), an internal threading (12) and also a tubular guiding portion (13). An annular member (14) surrounding the toothing (11) is rotatably mounted over the sleeve shaped member (5) and has a handle (28) and a reversible catch (22) to engage the toothing. A coupling member (29) to be threadingly connected to the sleeve shaped member (5) has for that purpose an external threading (30) as well as a saw tooth shaped, peripheral bead (31) to obtain a guide function by cooperation with the tubular guiding portion (13). A further coupling member (1) is rotatably but non-displaceably connected to the sleeve shaped member (5) and has in the end surface thereof a groove (3) having a dovetail section and an O-ring (4) inserted thereinto.

Abstract: A fluid coupling has a male member having a generally rigid base and an attached, relatively resilient face with a first fluid flow path opening from the resilient face. A female member of the coupling has a generally cylindrical receptacle with an opening for admitting the male member and a second fluid flow path for communication with the first fluid flow path in the male member when the male member is inserted into and rotated in the receptacle. The male and female members have cooperating cam surfaces opposite the opening into the fluid flow path in the member for urging the members together with a force directed at the opening. The force compresses the resilient face of the male member against the receptacle to seal the fluid flow paths about the openings. The preferred embodiment is a T coupling in which the male member has a third fluid flow path extending through it and in communication with the first fluid flow path.

Abstract: A hose coupling is provided primarily for irrigation applications and features a quick-connect capability ideal for use with the flexible irrigation systems such as are used on sugar cane plantations and elsewhere requiring relatively frequent assembly and dismantling of the system, the coupling being characterized by a tubular body portion having a nipple over which a flexible irrigation hose is pulled, there being a collar on the connector body which by virtue of a pair of helical ramps is forced over the end of the irrigation hose locking it onto the nipple when the collar is twisted. Being unrestrained other than by the helical ramp structure, the collar can be pulled axially to directly engage the irrigation hose, or twisted to utilize the mechanical advantage inherent in the helical ramps so that dual alternative operative modes are inherent in the design.
