ABSTRACT:
A shuttle device provided with a rotating hook comprises a rotatable race secured to a verticle driving shaft. A bobbin carrier is journalled in the race and has a pair of spaced abutment faces on opposite sides of the path of the needle. The abutment faces cooperate with two spaced beaks on an oscillating escapement so that one of the beaks is always in contact with one of the abutment faces to prevent the carrier from rotating. The oscillation of the escapement permits a space to be left alternatively for each pair of cooperating beaks and abutment faces for the passage of the upper thread loop. The escapement is resiliently yieldable to prevent injury to the beaks or abutment faces, in the event of thread jamming between the sliding contact faces of the shuttle race and the bobbin carrier.
