Abstract:
The invention relates to a method for milking an animal, in particular a cow, according to which a characteristic (KG) of the milking operation is first determined. Said characteristic (KG) is composed of at least one of the following variables: the actual value (IW) of the milk flow (MF), the temporal modification of said flow and/or the accumulated quantity of milk (MM). A threshold value (SK) for determining the end of a milking operation is determined in accordance with the characteristic(s) (KG). The end of the milking operation is predicted using the characteristic (KG) and the threshold value (SK). An evaluation variable (BG) of the milking operation is determined during said milking operation, whereby this/these evaluation variable(s) (BG) take(s) into account at least one of the following variables: the actual value (IW) of the milk flow (MF), the temporal modification of said flow and/or the accumulated quantity of milk (MM). The end of the milking operation is initiated, when the evaluation variable (BG) essentially corresponds to the threshold value (SK), or falls below the latter.

The liner member includes a head portion and a tubular elongate inflation portion. The head portion includes an upper teat chamber defined with a cylindrical wall having an outer exposed surface, an intermediate wall extending substantially orthogonally inward from the cylindrical wall and an upper seal wall laterally extending inward from the cylindrical wall having a central opening defined by the upper seal wall. The cylindrical wall of the head portion includes a cylindrical retaining extension configured to cooperate with and be coupled to an upper end portion of the tubular sleeve. The tubular elongate inflation portion includes side walls with opposite first and second ends defining a liner bore longitudinally along a length of the tubular elongate inflation portion with opposite first and second open ends. The first end is integrally interconnected and extends from the intermediate wall of the head portion with the first open end opening into the upper teat chamber. The second end of the tubular elongate inflation portion is a free end. With this arrangement, the tubular elongate inflation portion is configured to be inserted through a sleeve bore defined in the tubular sleeve so that the cylindrical retaining extension is disposed around an upper end portion of the tubular sleeve. The inflation portion is configured to be placed in tension with the free end of the tubular elongate portion invertedly drawn around a lower end portion of the tubular sleeve with a portion of the milk receiving cup capturing the inverted free end between the lower end portion of the tubular sleeve with an interference fit.
Abstract:
A liner for use with a teat cup having a rigid hollow shell having a central aperture is shown. The liner comprises a teat chamber having an opening which extends axially therethrough and terminates in a distal end and which has an axial length greater in length than a length of a teat terminating in a distal tip which is to be inserted into the teat chamber. The distal tip of a teat is positioned in a spaced relationship from the distal end of the teat chamber. The liner includes a transition chamber having an axially extending reducing inner passageway which has an inlet contiguous to and communicating with the opening in the distal end. The inner passageway inlet has a dimension substantially equal to the opening and decreases in dimension to an outlet having an outlet dimension less that the inlet dimension. The transition chamber defines thereon a circumferentially extending cuff member configured to be passed through a central aperture in a shell and to them surround and urge the cuff member against a shell. A milk tube, having a receiving end and a discharge end, communicates with the outlet of the transition chamber. The discharge end is configured to be operatively connected to a milk claw.
