Abstract

Abstract A spindle adapted for mounting on the framework of a false twist texturizing machine. The spindle includes a platen having three bosses mounted perpendicularly thereon, the bosses being positioned on the platen to form a triangle. Friction discs are carried on the bosses and overlap one another to define a zig-zag path for the yarn. A two-piece fixed guide tube aligned with the center of the triangle formed by the bosses feeds the yarn into and out from the spindle. A motor pulley is mounted on a lever which pivotally attaches to the platen, the motor pulley being adapted to engage a tangential belt disposed adjacent the platen to impart rotary motion to the pulley. A belt drive interconnects the motor pulley with the bosses to rotate the same. A rod pivots the lever to engage or disengage the motor pulley with the tangential belt and control rotation of the bosses.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 106 words
In a spindle adapted for use on a false twist texturizing machine which comprises a fixed platen disposed adjacent a tangential belt, a motor pulley mounted on an axle substantially perpendicular to the platen for rotation upon engagement with the tangential belt, three bosses mounted on the platen parallel to the motor pulley, each boss carrying at least one friction disc rotatable thereon in response to rotation of the motor pulley, the improvement comprising: a lever pivotally attached to said platen, having said motor pulley mounted thereon, and means for pivoting said lever to cause engagement or disengagement of said motor pulley with said tangential belt.
Claim 2
Dependent Claim 106 words
In a spindle adapted for use on a false twist texturizing machine which comprises a fixed platen disposed adjacent a tangential belt, a motor pulley mounted on an axle substantially perpendicular to the platen for rotation upon engagement with the tangential belt, three bosses mounted on the platen parallel to the motor pulley, each boss carrying at least one friction disc rotatable thereon in response to rotation of the motor pulley, the improvement comprising: a lever pivotally attached to said platen, having said motor pulley mounted thereon, and means for pivoting said lever to cause engagement or disengagement of said motor pulley with said tangential belt.
Claim 3
Dependent Claim 15 words
A spindle according to claim 1, wherein the motor pulley is located above the platen.
Claim 4
Dependent Claim 15 words
A spindle according to claim 1, wherein the motor pulley is located below the platen.
Claim 5
Dependent Claim 48 words
A spindle according to claim 1, wherein said means for pivoting the lever comprises a rod extending substantially parallel to the plane of the platen, the end of the said rod having a drive dog thereon which moves in a slot machined in the end of the lever.
Claim 6
Dependent Claim 23 words
A spindle according to claim 1, wherein the motor pulley is located on the side of the tangential belt opposite said motor pulley.
Claim 7
Dependent Claim 18 words
A spindle according to claim 1, wherein said lever pivots about an axle firmly fixed to the platen.
Claim 8
Dependent Claim 27 words
A spindle according to claim 6, wherein the motor pulley is mounted on the lever on the same side of the tangential belt as the pivot axle.
