ABSTRACT:
A displaceable cover for the housing of a sewing machine loop catch mechanism comprises a plate fixed to a pin which in turn is rotatably and slidably mounted in relatively fixed bearings. A spring element exerts upon the pin both a torsion torque and downward axial thrust. Opening of the cover is accomplished by depressing one end of a pivoted lever to cause the other end thereof to raise the cover from engagement within the housing and allowing the spring elements to swing the cover into an open position.
