Abstract

Rotating hook shuttle device for sewing machine, which comprises a rotating bucket (1) integral with a substantially vertical drive shaft (2), the hook (7) being formed on the edge of this bucket (1) which has internally a support part (8) of a bobbin (9) intended to supply the lower thread (10), the loop (32) of the upper thread being intended to be directed by the needle (12) which moves substantially parallel to the axis of the bucket (1) and tangentially to the hook (7), retaining in position, by means of a stop mechanism, the bobbin holder (8) (9) against all drag by the hook (7), this mechanism comprising two stops (13, 14) carried by the bobbin holder (8) (9) and arranged at either end of the needle path (12), presenting an exhaust (18) oscillating under the action of a rotating cam (27), two floors (19 and 20) cooperating respectively with the two stops (13, 14), so that one of the peaks s (19,20) is always in contact with one of the stops (13, 14), allowing the exhaust oscillation (18) to alternatively leave a space (j, k) between each pair of peaks (19, 20) and stop (13, 14) cooperating, this stops the passage (32) of the upper thread (11), characterized by the fact that the axis (22) of oscillation of the exhaust (18) is substantially parallel to the axis (2) of rotation of the hook (7), the control cam (27) of said exhaust (18) being integral with the drive shaft (2) of said hook (7) and arranged under the tray (1), comprising the exhaust (18) a plate (21) guided substantially horizontally under the tray (1) and against which the cam (27) acts, this plate (21) presenting two extensions (30, 31) folded upwards and whose end constitutes each of the peaks (19, 20), the axis (22) of oscillation of the exhaust (18) being located approximately in a median position between the two peaks (19, 20), this axis (22) being parallel to that of the cam (27), so that any oscillating movement of the bobbin holder (8) (9) is avoided.
