Abstract
Abstract The invention relates to milking apparatus in which the milk line and droppers, which convey milk under vacuum from teat-cup clusters to a receiving jar, are enclosed over their major length in a water-jacket through which water is directed in a direction contrary to the flow of milk. In this way the milk is pre-cooled before it is received in the receiving jar and frothing of the milk in the receiving jar is reduced so eliminating contamination of the vacuum line by froth. The water jacket is provided with warm-water outlets for drawing off warm water from the water-jacket for washing purposes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
130 words
Milking apparatus comprising a milk line for conveying milk from a plurality of teat-cup clusters to a receiving vessel, comprising a milk conduit, means for separately attaching each of a plurality of teat-cup clusters to said conduit at spaced points along said conduit for flow of milk in one direction through said conduit, a water-jacket surrounding said conduit, means to introduce relatively cold water into said jacket for flow of water through said jacket in a direction opposite to said one direction, means for withdrawing from said water-jacket relatively warm water heated by the milk in the milk conduit, a dropper line connected to each of a plurality of said connecting means for connecting a said connecting means to a teat-cup cluster, and a water-jacket about each said dropper line.
Claim 2
Dependent Claim

Milking apparatus comprising a milk line for conveying milk from a plurality of teat-cup clusters to a receiving vessel, comprising a milk conduit, means for separately attaching each of a plurality of teat-cup clusters to said conduit at spaced points along said conduit for flow of milk in one direction through said conduit, a water-jacket surrounding said conduit, means to introduce relatively cold water into said jacket for flow of water through said jacket in a direction opposite to said one direction, means for withdrawing from said water-jacket relatively warm water heated by the milk in the milk conduit, a dropper line connected to each of a plurality of said connecting means for connecting a said connecting means to a teat-cup cluster, and a water-jacket about each said dropper line.
Claim 3
Dependent Claim
33 words
Milking apparatus as claimed in claim 1, said water-jacket being in a plurality of sections, said connecting means being secured to the portions of said milk line which are disposed between said sections.
Claim 4
Dependent Claim
28 words
Milking apparatus as claimed in claim 1, the cross-sectional area of the interior of said conduit being greater than the cross-sectional area of the interior of said water-jacket.
Claim 5
Dependent Claim
29 words
Milking apparatus as claimed in claim 3, the water-jacket being annular and the milk line being tubular in cross-sectional configuration and the ratio of their diameters being about 6:5.
Claim 6
Dependent Claim
59 words
Milking apparatus as claimed in claim 1, the water-jacket and the milk line being tubular and being in eccentric relationship to each other with the top outer wall of the milk line in contact with the top and inner wall of the water-jacket to leave a substantially crescent shaped water passage around the lower portion of the milk line.
Claim 7
Dependent Claim
24 words
Milking apparatus as claimed in claim 5, the ratio of the diameter of the water-jacket to that of the milk line being about 6:5.
