Abstract
A loop taker mechanism and bobbin carrier for a sewing machine in which the bobbin carrier is formed of three components and is journalled in a rotary hook casing. An oscillating escapement yoke has two spaced beaks which cooperate with abutment faces on the carrier to prevent the carrier from rotating. One of the beaks carries an over-hanging guide plate which is wider than the beak and serves to prevent a thread loop from moving behind the beak and fouling the operation of the machine.
