A sewing machine adapted to be mounted in a support member, comprising a column mounted on a lower frame member having a free arm portion extending therefrom, said column carrying an upper arm disposed generally parallel to the free arm portion and terminating in a head in which a drive mechanism of a needle carrying bar is provided, said lower frame member being pivotally connected to a casing by means of at least two support members pivoted at one of their ends to the frame member and pivoted at their other ends to the casing, characterized in that said support members connect said lower frame member to said casing in such a manner as to permit displacement of the machine with respect to the casing between a first position in which the lower framework member and the free arm are housed in said casing, with their upper faces being generally at the level of the upper edge of the casing, and a second position in which the free arm is on the elevated position above the casing.
