TEAT CUP FOR USE IN CONNECTION WITH MILKING MACHINES Filed NOV. 27, 1950 INVENTOR HERBERT E. SKETT By I WM,
the lower open end of the liner 1). A tapered ring d, preferably made of metal, is caused to slide over the liner so that the latter is jammed between the internal surface of the ring and an external tapered surface of the bowl. The assembly is completed by placing a resiliently deformable locking ring e, upon shoulder ,f of plug 0. The ring e is preferably of rubber, and has its outside diameter slightly greater than the diameter of the lower opening of the shell where- 1 by it will be forced by the shell a into engagement with the shoulder f due to the upward force exerted upon the plug 0 by the extension of the liner b and retain the shell a, liner b and plug 0 as a completely assembled teat cup unit.
The tool illustrated in Fig. 2 comprises a rigid vertical peg g mounted on a fiat base g. the bowl and the liner have been secured together, and after the liner has been inserted in the shell, the assembly is placed on the peg with the hooded portion of the liner pointing towards the base. The peg will then engage the inside of the hollow plug, and,'on pressure being applied to the teat cup, the peg will push the plug through one end of the shell, thus applying tension to the liner, and allowing the locking ring to be attached. v
I claim: 7
1. A teat cup for use with a milking machine comprising an outer rigid shell open at its upper and lower ends, an extensible tubular liner disposed within said shell and having its upper portion overlying the upper end of said shell, a connector plug having an upper and lower portion, said upper portion of said plug being of greater external diameter than the internal diameter of said tubular liner to assure a fit of said liner thereover, the lower portion of said plug being adapted to receive a milk tube, said upper portion of said plug joining said lower section at a flared portion defining a shoulder, the maximum diameter of said plug being slightly less than the diameter of the lower opening of said shell, means in engagement with said liner for retaining said liner and the upper portion of said plug in positive frictional engagement, and a resiliently deformable locking ring adapted to seat upon the shoulder of said plug and having a diameter slightly greater than the diameter of the opening of the lower end of said shell whereby said plug is prevented from being pulled up into said shell under the force of said extensible liner.
2. A teat cup for use with a milking machine After comprising an outer rigid shell open at its upper and lower ends, an extensible tubular liner disposed within said shell and having its upper portion overlying the upper end of said shell, a connector plug having an internal bore axially therethrough, said connector having upper and lower portions of inverted frusto-conical form, said upper portion joining said lower portion at an outwardly flared portion defining a shoulder, the lower portion of said tubular liner being extended over the conical base of the upper portion of said plug, means for insuring positive engagement between the lower end of said liner and the upper portion of said plug, the lower portion of said plug being adapted to receive a milk tube, the maximum outside diameter of said plug being slightly less than the internal diameter of the lower end of said shell, and a resiliently deformable locking ring adapted to seat upon the shoulder between the upper and lower portions of said plug, said locking ring having a diameter slightly greater than the diameter of the opening of the lower end of said shell whereby said plug is prevented from being pulled up into said shell under the force of said extensible liner.
3. A teat cup as claimed in claim 2 wherein said means for insuring positive engagement between the lower end of said liner and the upper portion of said plug is a tapered ring axially slidable partially over the upper portion of said plug for retaining the lower end of the liner in positive engagement with the upper inverted frusto-conical portion of said plug, the taper of said ring being frusto-conical with the base of the taper being inverted as is the upper portion of said plug.
