    • Inflation of a bellows encased within a main cylindrical body caused by timed introduction of compressed air pushes down a slider overcoming a spring force and the lower end of the slider forces a pair of swingable pawls to move to the open disposition overcoming a spring force through vertical slots formed through the main cylindrical body shell. A downwardly open hood-shaped skirt may be disposed to the cylindrical body for reliable registration of the hanger at the bobbin and undesirable corotation of the bobbin with the spindle at the time of bobbinspindle engagement is prevented by a frictional member disposed to the skirt.
