The crank rod is pivotally connected with a drive carriage. By means of a pawl the drive carriage can be connected with a driver which is fastened on the needle bar. The driver in its turn is able to be secured in an upper deadpoint position by means of a controllable holding pawl with the simultaneous separation or disconnection of the drive carriage.
