Abstract

Abstract A milking machine milk line nipple assembly having a flexible resilient sleeve member with transverse corrugations formed therein secured to the milk line nipple at its inner end in telescoping encasing relation and having a rigid ring member at its outer end mounted in sliding relation to the nipple and being longitudinally compressible or collapsible relative to the nipple to permit ready attachment of the milking machine connector to the nipple and automatically return to contamination protective encasing relation to the nipple upon withdrawal of the milking machine connector.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 167 words
A milking machine milk line nipple assembly Comprising: a. a milk line, b. nipple structure extending laterally from said milk line and having an open outer end adapted to receive a milking machine connector line thereon, c. nipple closing mechanism carried by said milk line and including a closure member resiliently urged toward nippleclosing position across the open outer end of said nipple structure, d. a bellows-type sleeve member carried by said nipple structure is encased relation and extending along the major portion of the length thereof, e. said sleeve member being resiliently and compressible along its longitudinal axis, and f. a rigid ring member carried by the outer end portion of said sleeve member in axially aligned relation and having a bore only slightly greater than the exterior diameter of said nipple and terminating at the end of the nipple when said sleeve member is in non-compressed position and bearing against said closure member to cooperatively effectively prevent contamination of said nipple while not in use.
Claim 2
Dependent Claim 167 words
A milking machine milk line nipple assembly Comprising: a. a milk line, b. nipple structure extending laterally from said milk line and having an open outer end adapted to receive a milking machine connector line thereon, c. nipple closing mechanism carried by said milk line and including a closure member resiliently urged toward nippleclosing position across the open outer end of said nipple structure, d. a bellows-type sleeve member carried by said nipple structure is encased relation and extending along the major portion of the length thereof, e. said sleeve member being resiliently and compressible along its longitudinal axis, and f. a rigid ring member carried by the outer end portion of said sleeve member in axially aligned relation and having a bore only slightly greater than the exterior diameter of said nipple and terminating at the end of the nipple when said sleeve member is in non-compressed position and bearing against said closure member to cooperatively effectively prevent contamination of said nipple while not in use.
Claim 3
Dependent Claim 38 words
The structure defined in claim 1 wherein said sleeve member is made of a flexible resilient material and has a plurality of longitudinally spaced circumferentially extending corrugations formed therein to facilitate longitudinal compression relative to said sleeve member.
Claim 4
Dependent Claim 42 words
The structure defined in claim 1 wherein said sleeve member has an inner end portion and a radially inwardly extending annular flange element carried by said inner end portion and engaging the exterior of said nipple to secure said sleeve member thereto.
Claim 5
Dependent Claim 146 words
A nipple protector for milking machine milk lines comprising: a. a bellows-type sleeve member compressible along its longitudinal axis and having an inner diameter larger than that of such a nipple and being adapted to receive the same in telescoping surrounding relation; b. said sleeve member having an inner end portion and an outer end portion; c. said inner end portion of said sleeve member having a radially inwardly extending annular flange element adapted to engage the exterior of such a nipple when said sleeve member is slid thereover and to secure said member thereto; and d. a rigid ring member carried by the outer end portion of said sleeve member in axially aligned relation, said ring member having a bore only slightly greater than the exterior diameter of such a nipple and terminating at the end of the nipple when applied thereto in non-compressed position.
Claim 6
Dependent Claim 146 words
A nipple protector for milking machine milk lines comprising: a. a bellows-type sleeve member compressible along its longitudinal axis and having an inner diameter larger than that of such a nipple and being adapted to receive the same in telescoping surrounding relation; b. said sleeve member having an inner end portion and an outer end portion; c. said inner end portion of said sleeve member having a radially inwardly extending annular flange element adapted to engage the exterior of such a nipple when said sleeve member is slid thereover and to secure said member thereto; and d. a rigid ring member carried by the outer end portion of said sleeve member in axially aligned relation, said ring member having a bore only slightly greater than the exterior diameter of such a nipple and terminating at the end of the nipple when applied thereto in non-compressed position.
Claim 7
Dependent Claim 17 words
The structure defined in claim 4 wherein said sleeve member is comprised of a flexible resilient material.
Claim 8
Dependent Claim 42 words
The structure defined in claim 4 wherein said sleeve member is elongated and has a plurality of longitudinally spaced circumferentially extending corrugations formed therein to facilitate longitudinal compression thereof along the length of such a nipple when secured thereto in encasing relation.
