Abstract
A lockstitch sewing machine is provided with an elongate resilient member which is affixed at one end in the machine and extends under the feed dog of the machine for engagement thereby. The resilient member is flexed by the feed dog during downward movement thereof and then acts against bobbin thread pulling it from the bobbin spool. The elongate member relaxes and separates from the bobbin thread during upward movement of the feed dog.
