In connection with an escapement which comprises a flying dog which for causing each escapement step of the carriage reaches out counter to the letter feed direction, there is provided a device which incidental to carriage return motion is operated by friction drag influence to block first said dog against outreaching movement and then to disengage said dog, the device being effective by a short advance movement of the carriage following the return movement to reapply the dog. The device is also operated by the tabulation control mechanism for durations of tabulating runs but not resultant to friction drag influence. |
