ABSTRACT:
A device for selectively displacing sewing machine hooks to a position whereat they are readily accessible to an operator for threading purposes. The device includes a lever member pivotably mounted on the shaft which supports the hooks and an arm in the form of a cylindrical seat fixed on the shaft which carries a spring biased pin that is continuously urged into driving engagement with the lever member to effect oscillating movement of the shaft. A manually operable member is provided for disengaging the pin from driving engagement with the lever which permits the shaft to be rotated to a position that places the hooks carried thereby in an accessible position.
