Claims
- 1. A resilient coupling device for a double-twist twisting mechanism, comprising, a centered assembly rotatable about a first axis and an off-centered assembly which rotates about a second axis which is adjacent to but not concentric with the first axis, each of said assemblies having at least two fastening means spaced from their respective axes, and a pair of oppositely-acting connecting means which each connect a fastening means on one assembly with a fastening means on the other assembly whereby rotation of one assembly will produce rotation of the other assembly, each connecting means including a substantially unstretchable flexible traction element and a compressibly deformable resilient element located between the traction element and a said fastening means.
- 2. The coupling device of claim 1, wherein the fastening means is a pin and each of the resilient elements is a bearing which is mounted on said pin, each of said bearings having a groove receiving the pin, said pin being oriented substantially perpendicular to the traction element.
- 3. The coupling device of claim 2, wherein each of the traction elements is a closed loop.
- 4. The coupling device of claim 2, wherein each of the traction elements is a flexible cable.
- 5. The coupling device of claim 4, wherein the ends of the cable each comprise an eye closed by a crimped sleeve.
- 6. The coupling device of claim 5, wherein the eye is surrounded by a sheath.
- 7. The coupling device of claim 4, having a head at each end of the cable, a lug having a slotted aperture receiving said head, said lug being fitted onto a said bearing.
- 8. The coupling device of claim 7, wherein the slotted aperture includes a first bore parallel to the pin, a slot parallel to the cable and intersecting said first bore, a second bore perpendicular to said slot and offset to provide an edge which is closer to the slot exit than the intersection of the said first-mentioned bore with the said slot.
- 9. A coupling device as claimed in claim 1, wherein each of the traction elements is a cable having a head at each end thereof, each of the resilient elements being disposed with its axis positioned along the direction of the cable, each of said fixing elements including a blind bore, said head being disposed inside said blind bore, and radial slots in the respective bearing as far as the level of the cable to enable the cable to be inserted laterally therein, the said blind bore being slightly deeper than the axial length of the bearing to allow the head to be received in the bore.
- 10. A coupling device as claimed in claim 1 wherein the deformable element is compressed when the device is at rest.
