Driven spinning ring device for yarn machines

Claim 2

A spinning ring device for a yarn machine comprising a traveler for guiding yarn in a winding operation about a winding axis, a support ring for the traveler for guiding it in a circular path around the winding axis under the influence of the yarn, a mounting for supporting the ring on the winding axis, a ring holder rotatably mounted in said mounting to enable the ring to rotate in the same direction as the traveler to decrease the relative movement between the ring and the traveler, a stationary bearing support accommodated by the mounting and receiving the ring holder rotatably therein, bearing means interposed between said stationary bearing support and said ring holder to permit the ring holder to rotate within said bearing support, a pair of drive transmitting surfaces formed on the ring holder, driving means in engagement with one of said surfaces for driving the ring holder and driven means in engagement with the other of said surfaces for transmitting drive from the ring holder to at least one other ring holder.

Claim 3

A spinning ring device as set forth in claim 1 in which motion is imparted to the mounting in the direction of the axis of the ring holder and in which the driving means includes drive belt means carried with the mounting and engaging one of the said drive transmitting surfaces and an elongated drive shaft in driving engagement with said drive belt means and having an axis parallel to the axis of rotation of the ring holder so that the drive belt means moves longitudinally along the drive shaft.

Claim 4

A spinning ring device as set forth in claim 1 in which one of the drive transmitting surfaces includes a drive transmitting surface located on one side of the stationary bearing support and the other includes a drive transmitting surface located on the opposite side of the stationary bearing support.

Claim 5

A spinning ring device as set forth in claim 1 including a recessed bearing ring race formed in the outer periphery of the ring holder, a bearing recess formed in one end of said bearing support for accommodating the bearings therein in engagement with the recessed bearing race formed in the outer periphery of the ring holder, and a bearing retainer closing said end of the bearing support for retaining the bearings within the recessed bearing race.

Claim 6

A spinning ring device for a yarn machine comprising a traveler for guiding yarn in a winding operation about a winding axis, an annular support ring for the traveler for guiding it in a circular path around the winding axis under the influence of the yarn, a stationary bearing support accommodating bearings for supporting the ring on the winding axis, an annular ring holder rotatably mounted in said bearing support to enable the ring to rotate in the same direction as the traveler to decrease the relative movement between the ring and the traveler, an internal annular surface in the upper end of the ring holder, an integrally formed flange on the ring telescoping into said internal annular surface at the upper end of the ring holder, a recess formed in the ring holder adjacent the lower outer region of the ring flange, said traveler extending from the outer periphery of the ring across the upper end thereof and then downwardly terminating in a lower hook end which enters the recess, a pair of drive transmitting surfaces on the ring holder, one below the stationary bearing support and the other above the stationary bearing support, a driving belt in engagement with one of said surfaces for driving the ring holder, and a driven belt in engagement with the other of said surfaces for transmitting drive from the ring holder to another ring holder.

Claim 7

A spinning ring device for a yarn machine comprising a traveler for guiding yarn in a winding operation about a winding axis, an annular support ring for the traveler for guiding it in a circular path around the winding axis under the influence of the yarn, a stationary bearing support accommodating bearings for supporting the ring on the winding axis, an annular ring holder rotatably mounted in said bearing support to enable the ring to rotate in the same direction as the traveler to decrease the relative movement between the ring and the traveler, an internal annular surface in the upper end of the ring holder, an integrally formed flange on the ring telescoping into said internal annular surface at the upper end of the ring holder, a recess formed in the ring holder adjacent the lower outer region of the ring flange, said traveler extending from the outer periphery of the ring across the upper end thereof and then downwardly terminating in a lower hook end which enters the recess, a pair of drive transmitting surfaces on the ring holder, one below the stationary bearing support and the other above the stationary bearing support, a driving belt in engagement with one of said surfaces for driving the ring holder, and a driven belt in engagement with the other of said surfaces for transmitting drive from the ring holder to another ring holder.

Claim 8

A spinning ring device as set forth in claim 5 including an annular recess in the outer periphery of the ring holder and at least partially receiving the bearing therein for rotatably supporting the ring holder.

Claim 9

A spinning ring device as set forth in claim 5 in which the bearings are ball bearings and including tubular separators intermediate pairs of ball bearings and containing a lubricant which is accessible to the ball bearings through the ends of the tubular separators.

Claim 10

A spinning ring device as set forth in claim 7 in which the separators are made of lightweight synthetic material.

Claim 11

A spinning ring device as set forth in claim 6 including a bearing recess formed in one end of said bearing support for accommodating the bearings therein to engage the annular recess in the ring holder, a bearing retainer closing said open end of said bearing support and a bearing race for the bearings defined by surfaces of the bearing support and the bearing retainer cooperating with said annular recess.

Claim 12

A spinning ring device as set forth in claim 5 including a platform which carries a plurality of rotatably mounted ring holders up and down the winding axis and in which the driven belt is a common belt in frictional engagement with said plurality of ring holders.
