Title: Traveler brakes for ring-twining and ring-spinning machines
Claims: The embodiments of the invention in which an exclusive property or privilege is claimed are defined as follows: 1. A spinning or twining apparatus, comprising: twining ring means having annular guide means thereon; support means for supporting said twining ring means; a traveler movably mounted on said annular guide means and guided for movement thereon; an annular brake ring coaxially positioned relative to said twining ring means, said brake ring being composed of an elastically flexible material; resilient means for resiliently suspending said brake means beneath said twining ring and for continuously urging said brake ring into braking engagement with the underside of said traveler, said material of said brake ring thereby minimizing wear on said traveler when said brake ring engages said traveler; and brake release means engaging said brake ring for urging said brake ring away from said braking engagement with said traveler against the urging of said resilient means. 2. A spinning or twining apparatus according to claim 1, wherein said brake ring is composed of foam rubber. 3. A spinning or twining apparatus according to claim 1, wherein said traveler is guided on both an upper and lower portion of said twining ring. 4. A spinning or twining apparatus according to claim 1, wherein said resilient means extends between said support means and said brake ring. 5. A spinning or twining apparatus according to claim 1, wherein said traveler is guided only on the upper flange of said twining ring and wherein said brake ring has an extension projecting into the interior of said twining ring to engage said bottom of said traveler. 6. A spinning or twining apparatus according to claim 1, wherein said brake release means comprises an axle extending in direction parallel to a tangent to said brake ring and a bifurcated member for said brake ring, said bifurcated member engaging a pair of diametrically opposite pins arranged parallel to said axle on said brake ring. 7. A spinning or twining apparatus according to claim 1, wherein the movement of said brake ring towards said twining ring is limited by adjustable stop means. 8. A spinning or twining apparatus, comprising: twining ring means having annular guide means thereon; support means for supporting said twining ring means; a traveler movably mounted on said annular guide means and guided for movement thereon; an annular brake ring concentrically positioned relative to and generally coplanar with said twining ring means, said brake ring being circumferentially noncontinuous to permit a movement of one end of said brake ring to effect a radial expansion and contraction of said brake ring relative to said twining ring means and said traveler, the other end of said brake ring being secured to said support means, said brake ring being composed of an elastically flexible material; and brake operating means operatively connected to said one end of said brake ring for effecting a radial movement of said brake ring into and out of engagement with a radial side of said traveler, said material of said brake ring thereby minimizing wear on said traveler when said brake ring engages said traveler. 9. A spinning or twining apparatus according to claim 8, wherein said one end of said brake ring is connected to a brake rod which is movable parallel to a tangent to said brake ring. 10. A spinning or twining apparatus according to claim 8, wherein said brake ring is outside said twining ring means, said brake operating means effecting a radial contraction of said brake ring to engage the radially outer surface of said traveler to halt the movement of said traveler.
