Bobbin hanger

A bobbin hanger comprising:

• a bobbin hanging tube having an upper expanded section and a lower reduced section extending from the expanded section;
• a sliding member pivotally supporting a pair of bobbin holding fingers at a lower position thereof, pivotally supporting a retaining member integrally provided with a ratchet and retaining projections at an upper position thereof, and axially slidably inserted in the reduced section of the bobbin hanging tube;
• a ratchet operating member having an operating leg for operating the ratchet of the retaining member;
• and
• a weight axially slidably put on the reduced section of the bobbin hanging tube, said weight being capable of being pushed up by a bobbin to push up the sliding member so that the retaining member is turned substantially through an angle of 90.degree. by the operating leg of the ratchet operating member engaging the ratchet of the retaining member to bring the retaining projections to a position for resting on the inner upper end of the reduced section of the bobbin hanging tube to retain the sliding member at a position where the bobbin holding fingers are allowed to swing outward to engage the inner surface of the bobbin;
• characterized in that the position of the upper end of the weight at the completion of turning of the retaining member is 4 to 10 mm below the lower end of the expanded section of the bobbin hanging tube, and the bobbin holding fingers have a shape capable of preventing the retraction of the bobbin holding fingers into the interior of the bobbin hanging tube when acted upon by a horizontal force.
