Abstract: A milking liner includes an integrated short air tube and short milk tube. In one configuration, the pulsation air is delivered through the bead of the milking liner directly inside the shell through a plurality of outlets. The disclosure also provides alignment features that assist the person assembling a milking liner and shell. The features limit rotation between the liner and the shell. The liner includes a short air tube that extends beyond a short milk tube with each having a sealing bead. The sealing beads are offset from each other.

Abstract: A milking liner includes an integrated short air tube and short milk tube. In one configuration, the pulsation air is delivered through the bead of the milking liner directly inside the shell when the liner is connected to the shell. In another configuration, the integrated short air tube has an outlet outside the shell. The disclosure also provides aligned nipple pairs on the claw top. One configuration is provided wherein the pulsation nipples and air fork are integrated with the claw that has the liner nipples. Another configuration is provided wherein the air fork is separate from the claw. A method of readily supplying pulsation air to a shell includes the step of integrated the step of connecting the short air tube and the shell with the step of connecting the shell to the milking liner.

Abstract: A teat cup shell for holding a milking liner includes a body being made from a first material. The body has an upper end, a lower end; and a middle portion with the upper end adapted to receive the teat of the animal being milked. One configuration of the body may have enlarged upper and lower ends to define a dog-bone shape. The middle portion of the body may define gripping features at its middle portion. The body of the shell has a first weight. An insert is carried by the body with the insert being heavier than the remaining portion of the body. The insert is disposed closer to the lower end of the body than the upper end of the body such that the center of mass of the shell is disposed in the lower two-thirds of the shell.

Abstract: A milking liner for an automated milking machine includes a barrel that moves between an uncollapsed position and a collapsed condition when it is subjected to a vacuum milking condition. The barrel defines at least three parallel channels open to the inner surface of the barrel. The configuration of the sidewall of the barrel and the channels cause the barrel to uniformly collapse when the barrel is subjected to a vacuum milking condition. In one configuration, ribs protrude from the barrel sidewall and define channels with the same wall thickness as the sidewall segments disposed between the ribs.

Abstract: A vent plug for a milking liner has an outlet that discharges the vent air in the downstream direction. The vent plug has an outlet disposed in the downstream portion of the inner flange of the vent plug so that vent air is directed toward the outlet of the short milk tube. The vent plug outlet also may be disposed in the upstream portion of the inner flange while being configured to direct the vent air in a downstream direction.

Abstract: A milking apparatus that is used to extract milk from dairy animals includes a vacuum source, a milking liner cooperating with a shell to define a pulsation chamber; and a pulsator in fluid communication with the pulsation chamber and the vacuum source. The pulsator is configured to produce at least a four-phase milking cycle in the milking liner with the cycle including at least an A phase and a C phase. The A phase is wherein the liner is changed from a closed configuration to an open configuration during which the pulsator provides fluid communication between the pulsation chamber and the vacuum source. The C phase is wherein the liner is changed from an open configuration to a closed configuration during which the pulsator allows atmospheric air to flow into the pulsation chamber. A restrictor is disposed in the path of the fluid communication between the pulsator and the pulsation chamber with the restrictor slowing the C phase compared to the A phase.

Abstract: A flooring system includes a preformed cushion layer made up of a plurality of individual preformed cushioning body sections that are sandwiched between sealant layers to provide a liquid-impervious flooring material. Methods for manufacturing the body sections and installing the flooring system are also provided.

Abstract: A vent plug for a milking liner has an inlet that faces the outer surface of the liner. The position of the vent inlet reduces the likelihood that it will become clogged with debris from the floor of the milking parlor. In one embodiment, the vent plug has a plurality of redundant inlets that allow the vent plug to function if one of the inlets becomes clogged. In another embodiment, the inlet is angled at a nonparallel angle with respect to the vent passage.

Abstract: A vent plug for a milking liner has a shielded inlet that reduces the likelihood that it will become clogged with debris from the floor of the milking parlor. In one embodiment, the vent plug has a plurality of redundant inlets that allow the vent plug to function if one of the inlets becomes clogged. In another embodiment, the inner flange of the body of the vent plug is at least twice the thickness of the body tube to help secure the vent plug in the milking liner.
