A milking cup comprises a tubular casing and a resiliently deformable sleeve extending through the casing and sealingly secured to each end of the casing. The inner space of the sleeve receives a nipple of an animal to be milked and the sleeve defines with the casing an outer space which can be connected by means of an aperture in the casing to a source of varying pressure, especially alternately applied vacuum and atmospheric pressure. At least one expandible body is provided in the outer space...

An elongated milking hose for a quarter milking machine. The milking hose has four elongated, flexible conduits, of which two conduits are connected to one another along a first common connecting segment, extending parallel with respect to the longitudinal axis of the hose. The two other conduits are each arranged on opposite sides of the first connecting segment of the two first conduits and extend parallel therewith and are each connected to the two first conduits along a second and third, and...

A milker has a lower base with a concave bottom and a lower exit under vacuum that can be closed by a float with valve until the milk level pivots and/or raises the float to open the exit. An enclosure body is fitted on the base and includes a main vacuum inlet and a milk inlet nipple positioned and angled to direct milk inflow at the side and/or below the float. An enclosure cap is releasably fitted on the top of the enclosure body and mounts an air valve, pulsation nipples and a further vacuum...

A milking apparatus is disclosed for automatically providing the appropriate amount of vacuum for purposes of milking a cow throughout the entire milking operation. The milking apparatus includes a fluid control valve system having a controller unit and a discharge valve in fluid communication with a collection jar. The controller unit is further adapted for communication with a source of vacuum, and the collection jar is adapted to be in communication with the cow such that the vacuum can draw ...

A milking plant of the kind operating at two different vacuum levels is provided with a vacuum source producing a low vacuum, and an ejector connected to the vacuum source and producing a high vacuum.

A milking machine has teat cups each provided between the shell and the liner with a pulse space subjected alternately to atmospheric pressure and a vacuum to expand and contract the liner while the space within the liner is subjected to a milking vacuum. When the milk flow rate is below a certain level, a monitoring apparatus automatically regulates the flow of air from the pulse space to effect a gradual opening of the liner, to avoid the usual sudden opening.

The invention concerns a device for removing the teat-cup cluster of a milking machine from the animal at the end of milking. The device comprises a container connected to the milk line from the teat-cups. The container is mounted on a fulcrum and when the container contains a certain volume of milk it tilts into an activated position. When the volume of milk in the container drops to a certain level the container tilts back to release a spring-loaded lever which then pinches the milk line to cu...

A raised platform-stall has a first part on which animals can be positioned for milking while feeding from a manger located at one side of the stall, and a second part of the stall forms a foot path along the side of the stall farthest from the manger. After the animals have taken up position in front of and at right angles to the manger, the second stall part can be pushed under the first part so that the milking personnel can readily apply the milking units from behind the animals.

The end of the milking inflation adapted to be slipped onto a nipple on the milker claw includes a thickened wall section in the region near the outer end of the claw nipple. The thickened wall section includes a plurality of axially-spaced, circumferentially-extending rows of circumferentially spaced external recesses which permit the thickened wall section to flex so that the inner wall thereof can sealingly engage the outer end of the claw nipple to shut off communication between the claw and...

The expansion ring type milking inflation is formed from an elastomeric material and has a tapered upper end portion which serves as a mouthpiece for receiving cow's teat. The upper end portion includes an expansion ring-receiving portion adjacent the juncture with the main body and terminates in a rounded bead which defines a circular opening or mouth when the expansion ring is inserted. The upper end portion also includes an annular web section of reduced wall thickness adjacent the bead which...
