Support means are provided with the needle threader which when moved to an operative position, unlatches the needle bar from its drive means and elevates it to an uppermost position and simultaneously moves the needle bar to a predetermined lateral position, permitting the bore of the needle threader to be readily located axially with the eye of the sewing needle.
