  • This rocking element is actuated in a 1rocking 'tuating mechanism described in a co-pending movement around its axle by an acapplication, so that the needle-carrier 5 is actuated in a to land iro lateral movement synchronised 'with lits vertical reciprocating movement.
  • The'lcwer arm "2 contains a rotary hook fixed von ii, which'asshown is inclined at an angle substantially vless than 90 land mechanicaily connected by transmission mechanisms to the'main shaft'Pof the sewing machine.
  • This rotary hook includes-a revolving cup Iii, iitted with a loop seizing beal: I2, intended for snapping the upper thread loop which is ⁇ formed on the side of the needle A at vthe beginning of the upward stroke o' the latter,
  • This cup contains a bobbin te (lig, 3i kept fixed ina support i3.

  • the upper thread f can pass freely between the stop I8 and the arm I6, when the lever I 9 is in the position shown on Fig.
  • the shaft II of the rotary hook is not only situated rin a vertical plane parallel with the needle-carrier and perpendicular to the advancement displacement of the feeding means, as is the case with certain known machines, but is in addition inclined in relation to the axis of the needlecarrier.
  • the beak I2 is situated, when it passes in front 'of the needle A, at a greater distance from the resting surface for the cloth 34, when this needle is displaced towards the right in relation to its middle position, than when the needle is displaced towards the left in relation to this middle position.
  • this beak I2 is always capable of catching correctly the loop formed by the upper thread
