Abstract
The thread retainer has a tube which is slotted from the side to form an access opening for a thread and a gate member in the form of a ball which is movably mounted in the tube. The ball cooperates with a second ball to define a thread passage with curvilinear walls. The movable ball may move under gravity or may be spring biased to permit entry of the thread into the thread passage.
