Abstract
Abstract A closing spindle for a bottle sealing and opening machine, comprising a spindle rotating about a vertical shaft and being mounted in a bottle turn-table. The spindle has at its lower end a tightening chuck in which a cap fits tightly. The spindle is arranged to have a positively directed, vertical movement during rotation about the vertical shaft. An ejection spindle extends through a central bore of the closing spindle and is axially slidable with a length greater than the total length of the rotating closing spindle. The ejection spindle may be selectively held constantly pressed upwardly or downwardly relative to the rotating spindle. At some distance above the upper end of the ejection spindle a stop is provided rigidly mounted on the sealing machine to limit the vertical upward movement of the ejection spindle. The ejection spindle is provided at its lower end with an adjustable stop collar cooperating with the lower end of the rotating spindle in the tightening chuck to limit the vertical movement of the ejection spindle relative to the rotating spindle.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
235 words
A closing spindle for use with a bottle sealing and opening machine having a bottle turn-table, said closing spindle comprising a vertical shaft mounted in said bottle turn-table, a spindle having a central bore and positioned to rotate about said vertical shaft, a tightening chuck into which a bottle cap fits tightly provided at a lower end of said rotating spindle, means cooperating with said rotating spindle to impart vertical movement to the rotating spindle during its rotation about said vertical shaft, an ejection spindle extending through the central bore of said rotating spindle, said ejection spindle being axially slidable and the length of said ejection spindle being greater than the total length of said rotating spindle, means cooperating with said ejection spindle for selectively holding the ejection spindle either in a constantly pressed upward or downward position relative to the rotating spindle, a first stop rigidly mounted on the sealing machine and positioned above an upper end of the ejection spindle to limit the vertical upward mOvement of said ejection spindle, and a first adjustable stop collar positioned adjacent the lower end of said ejection spindle and cooperating with the lower end of said rotating spindle in the chuck to limit the vertical downward movement of said ejection spindle relative to said rotating spindle when said holding means holds said ejection spindle in a downward position to center caps on bottles to be capped.
Claim 2
Dependent Claim
235 words
A closing spindle for use with a bottle sealing and opening machine having a bottle turn-table, said closing spindle comprising a vertical shaft mounted in said bottle turn-table, a spindle having a central bore and positioned to rotate about said vertical shaft, a tightening chuck into which a bottle cap fits tightly provided at a lower end of said rotating spindle, means cooperating with said rotating spindle to impart vertical movement to the rotating spindle during its rotation about said vertical shaft, an ejection spindle extending through the central bore of said rotating spindle, said ejection spindle being axially slidable and the length of said ejection spindle being greater than the total length of said rotating spindle, means cooperating with said ejection spindle for selectively holding the ejection spindle either in a constantly pressed upward or downward position relative to the rotating spindle, a first stop rigidly mounted on the sealing machine and positioned above an upper end of the ejection spindle to limit the vertical upward mOvement of said ejection spindle, and a first adjustable stop collar positioned adjacent the lower end of said ejection spindle and cooperating with the lower end of said rotating spindle in the chuck to limit the vertical downward movement of said ejection spindle relative to said rotating spindle when said holding means holds said ejection spindle in a downward position to center caps on bottles to be capped.
Claim 3
Dependent Claim
91 words
A closing spindle according to claim 1 wherein said central bore includes an enlarged portion defining an inner wall and wherein said holding means comprises a spiral compression spring, said spring being located around the upper part of the ejection spindle in said enlarged portion of the central bore, a second stop provided on the inner wall of the enlarged portion of the central bore, a third stop provided on the periphery of the ejection spindle and spaced from said second stop, said spring extending between said second and third stops.
Claim 4
Dependent Claim
175 words
A closing spindle according to claim 2 further including a collar sleeve provided in the enlarged part of the central bore, a shoulder formed in the central bore at the junction between the enlarged part of said bore and the remaining part having a smaller diameter, the collar of said sleeve lying on said shoulder a second stationary stop collar provided at the upper end of the ejection spindle, the collar sleeve and the second stationary stop collar forming stops, a first helical spring cooperating with said collar sleeve and said second stationary stop collar for applying a constant upward pressure on the ejection spindle, and a third stop collar provided in the upper end of the enlarged part of the central bore, said third stop collar being removably attached to the inner wall thereof, and a fourth stop collar located a distance below said third stop collar at the periphery of the ejection spindle and removably attached to said ejection spindle, and a second helical spring positioned between said third and fourth stop collars.
Claim 5
Dependent Claim
106 words
A closing spindle according to claim 1 wherein the means for imparting vertical movement to the rotating spindle comprises a cylindrical body provided around the periphery of the rotating spindle and in which body the rotating spindle may rotate, said body being secured against axial displacement relative to the rotating spindle, a first horizontal shaft, a first roller rotatable about said horizontal shaft and located at the periphery of said body, a cylindrical cam cooperating with said roller so that said cam will run below said roller during the rotation of the rotating spindle, and means cooperating with said body to prevent rotation of the body.
Claim 6
Dependent Claim
59 words
A closing spindle according to claim 4 wherein the means for preventing rotation of the body provided with a cam roller comprises a second roller attached to the periphery of the body and rotatable about a second horizontal shaft, a stationary guide means cooperating with said second roller, said guide means extending in vertical direction along the closing spindle.
Claim 7
Dependent Claim
49 words
A closing spindle according to claim 4 further including a gear wheel, said cam being provided on the upper side of said gear wheel, said wheel being provided below the cam roller, and a pinion located for meshing with the gear wheel and for rotatably driving the rotating spindle.
Claim 8
Dependent Claim
49 words
A closing spindle according to claim 1 further including a cylindrical casing, and an adjustable disconnecting coupling the tightening chuck being exchangeable and said chuck being applied to the rotating spindle through said cylindrical casing, said casing being rotatably connected to said closing spindle via said adjustable disconnecting coupling.
