Abstract
A reversible mechanism including a driven member with a rim having drive surfaces on its opposite sides. An elongate driving member is flexibly engageable with either of these surfaces at a predetermined position. The mechanism is useful in conjunction with a manually operated motor for controlled winding or unwinding of strands or yarns. It is also adaptable for reversal of movement by providing an extremity or extremities on the rim which, upon movement to the predetermined position, allow the driving member to disengage from one surface of the rim and to engage the other surface.
Claims10
A drive mechanism having, in combination,
- a driven member having a rim defined by a pair of surfaces on opposite sides thereof,
- means to support the driven member for movement in either of two opposite directions to cause the rim to move progressively through a predetermined position,
- a rotary drive motor having a shaft and an elastic elongate drive member mounted on the shaft coaxially therewith, the drive member having a free end,
- and means to support the drive motor in a location for interfering engagement between said free end of the drive member and one of said surfaces at said predetermined position, the drive member including means to bend resiliently and longitudinally from one of said sides to the other while said drive motor remains in said location to cause the drive member to make frictional engagement with either of said surfaces.
A drive mechanism having, in combination,
- a driven member having a rim defined by a pair of surfaces on opposite sides thereof,
- means to support the driven member for movement in either of two opposite directions to cause the rim to move progressively through a predetermined position,
- a rotary drive motor having a shaft and an elongate drive member mounted on the shaft coaxially therewith, the drive member having a free end,
- and means to support the drive motor in a location for interfering engagement between said free end of the drive member and one of said surfaces at said predetermined position, the drive member including means to bend resiliently and longitudinally from one of said sides to the other while said drive motor remains in said location to cause the drive member to make frictional engagement with either of said surfaces, the rim having an extremity which, upon movement to said predetermined position, permits the drive member to disengage from either of said surfaces and to engage the other of said surfaces, whereby the movement of the driven member is reversed.
A drive mechanism having, in combination,
- a driven member having a rim defined by a pair of surfaces on opposite sides thereof,
- means to support the driven member for rotation about an axis in either of two opposite directions to cause the rim to move progressively through a predetermined position, said axis being fixed in relation to said predetermined position, the driven member having provision to support a plurality of bodies of yarn in offset relation to said axis,
- a rotary drive motor having a shaft and an elongate drive member mounted on the shaft coaxially therewith, the drive member having a free end,
- a manually operable switch for connecting power to the drive motor,
- and means to support the drive motor in a location for interfering engagement between said free end of the drive member and one of said surfaces at said predetermined position, the drive member including means to bend resiliently and longitudinally from one of said sides to the other while said drive motor remains in said location to cause the drive member to make frictional engagement with either of said surfaces.
