ABSTRACT:
A sewing machine has an upper arm and a lower free arm carried by a column and two longitudinal supports disposed on either side of the free arm and connected to the base of the column. At least one of the supports is slidable laterally outwards from a position closing off the free arm to a position allowing access to the free arm under the action of a biasing spring, but is retained in the withdrawn position by a catch cooperating with an abutment on a transverse guide rod fixed on the support.
