SINGER 404K - Manual (Page 4)

Throat Plate —the plate in the bed directly below the presser foot through
which the needle passes and the feed dog moves.
Feed Dog —the toothed part which projects upward through slots in the
throat plate, carrying the fabric from the operator at each stitch. The
movement of the feed dog is controlled by the stitch regulator which
determines the desired length of stitch.
Bed Slide —the flat plate or plates at the left of the bed, which may be
opened to give access to the shuttle or bobbin case and other parts of
the lower stitch-forming mechanism.
Bobbin —the spool on which thread is wound to furnish the lower or shuttle
thread supply.
Shuttle or Bobbin Case —the container in which the bobbin is placed and
around which the loop of the needle thread is passed in forming the
lock stitch.
Rotary or Oscillating Hook —the part which enters the loop of needle
thread and carries it around the bobbin case. In the long-bobbin
machine (Singer No. 128) this function is performed by the shuttle,
which also acts as a bobbin case.
Lower Tension —the spring on the shuttle or bobbin case, which controls the
tension on the thread from the bobbin.
Cabinet Work —all the wood parts.
Stand —the supports and driving parts on which the cabinet work is mounted.
Treadle —the platform rocked up and down with the feet to operate the
machine.
Pitman —the rod connecting the treadle and the band wheel.
