Abstract
Abstract There is disclosed a device and method for testing automatic milking machines and parts thereof for inflation wear, teat message, basic pulsator malfunctions, vacuum instability as the cow milks, and vacuum recovery capacity. The device contemplated is an elongated frustoconical body member having an axially centered bore communicating with a vacuum gauge. A gradually tapering conical surface is provided on the body member with indicia at selected intervals thereon for indicating depth of penetration into a teat cup inflation element and thus the condition of the element and its likelihood to cause injury to the cow.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
107 words
A device for testing teat cup inflation elements and vacuum systems in a milking machine comprising, an elongated frustoconically shaped circular body section having an axially centered bore therein, the ratio of diameter of the base of said elongated frustoconical body section being slightly greater than the diameter of the smaller end thereof to form a gradually tapering conical indicating surface and to form a seal at any section thereof to the teat entrance orifice of the teat cup inflation element, indicia means on said indicating surface for indicating the condition of the teat cup inflation element, and a vacuum gauge connected to said axially centered bore.
Claim 2
Independent Claim
107 words
A device for testing teat cup inflation elements and vacuum systems in a milking machine comprising, an elongated frustoconically shaped circular body section having an axially centered bore therein, the ratio of diameter of the base of said elongated frustoconical body section being slightly greater than the diameter of the smaller end thereof to form a gradually tapering conical indicating surface and to form a seal at any section thereof to the teat entrance orifice of the teat cup inflation element, indicia means on said indicating surface for indicating the condition of the teat cup inflation element, and a vacuum gauge connected to said axially centered bore.
Claim 3
Dependent Claim
94 words
The device defined in claim 1 including a further frustoconically shaped circular body section, the base diameter of said further section being equal to the small diameter end of said elongated conically shaped body section, the ratio of the base diameter of said further frustoconical section to the diameter of the small end thereof being substantially greater than the ratio of the diameter of said elongated frustoconical member to form a guiding protuberance therefor, and said further frustoconical body having an axially centered bore therein aligned with the bore in said elongated frustoconical sections.
Claim 4
Dependent Claim
42 words
The device defined in claim 2 including a cylindrically shaped section having a diameter equal to the diameter of the small end of said further frustoconical section and an axially centered bore therein aligned with the bore in said further frustoconical section.
Claim 5
Dependent Claim
18 words
The invention defined in claim 3 wherein said frustoconically shaped sections and said cylindrically shaped sections are integral.
Claim 6
Dependent Claim
51 words
The invention defined in claim 2 wherein said indicia means is constituted by a plurality of lines, the first being spaced from the base diameter of said further section, and wherein the diameter of said conical section at said first line is twenty-nine thirty-seconds inch plus or minus one sixty-fourth inch.
Claim 7
Independent Claim
108 words
A method of testing the condition of a teat cup inflation element as used in a milking machine comprising the steps of, placing an elongated frustoconically shaped body section in juxtaposition to the teat entrance orifice of a teat cup inflation element, said frustoconical body section having a right circular cross-sectional diameter of about twenty-nine thirty-seconds inch plus or minus one sixty-fourth inch spaced a short distance from the small end thereof, applying a force of about 5 pounds pressure to said frustoconical section, determining the extent of penetration of said frustoconical element into said teat entrance orifice as a measure of the quality of said inflation element.
Claim 8
Independent Claim
108 words
A method of testing the condition of a teat cup inflation element as used in a milking machine comprising the steps of, placing an elongated frustoconically shaped body section in juxtaposition to the teat entrance orifice of a teat cup inflation element, said frustoconical body section having a right circular cross-sectional diameter of about twenty-nine thirty-seconds inch plus or minus one sixty-fourth inch spaced a short distance from the small end thereof, applying a force of about 5 pounds pressure to said frustoconical section, determining the extent of penetration of said frustoconical element into said teat entrance orifice as a measure of the quality of said inflation element.
Claim 9
Dependent Claim
95 words
The invention defined in claim 6 wherein the surface of said frustoconical element is provided with indicia means, the first of which is at a right cross-sectional area of said frustoconical section having a diameter of about twenty-nine thirty-seconds inch plus or minus one sixty-fourth inch, a second of which is at a right circular cross-sectional area having a diameter of about fifteen-sixteenths inch plus or minus one sixty-fourth inch and a third of which is at a right cross-sectional area having a diameter of about thirty-one thirty-seconds inch plus or minus one sixty-fourth inch.
Claim 10
Independent Claim
158 words
A device for testing the condition of a teat cup inflation element in a milking machine comprising, an elongated conical body member, said body member having a base end of right circular cross-sectional area having a diameter greater than thirty-one thirty-seconds inch plus or minus one sixty-fourth inch and a small teat cup orifice entry end which is less than twenty-nine thirty-seconds inch plus or minus one sixty-fourth inch, indicia means on the surface of said body member comprising at least a first indicia line located at a right circular cross-sectional area of said member having a diameter of twenty-nine thirty-seconds inch plus or minus one sixty-foUrth inch, a second indicia line located at a right circular cross-sectional area having a diameter of fifteen-sixteenths inch plus or minus one sixty-fourth inch and a third indicia line located at a right cross-sectional area of said member having a diameter of thirty-one thirty-seconds inch plus or minus one sixty-fourth inch.
Claim 11
Independent Claim
158 words
A device for testing the condition of a teat cup inflation element in a milking machine comprising, an elongated conical body member, said body member having a base end of right circular cross-sectional area having a diameter greater than thirty-one thirty-seconds inch plus or minus one sixty-fourth inch and a small teat cup orifice entry end which is less than twenty-nine thirty-seconds inch plus or minus one sixty-fourth inch, indicia means on the surface of said body member comprising at least a first indicia line located at a right circular cross-sectional area of said member having a diameter of twenty-nine thirty-seconds inch plus or minus one sixty-foUrth inch, a second indicia line located at a right circular cross-sectional area having a diameter of fifteen-sixteenths inch plus or minus one sixty-fourth inch and a third indicia line located at a right cross-sectional area of said member having a diameter of thirty-one thirty-seconds inch plus or minus one sixty-fourth inch.
