发明名称 Typewriter cable tensioning mechanism
摘要 A typewriter carriage cable snubber which is automatically reset at the time power is turned on is described. The cable is normally tensioned by a mechanism which is spring driven to maintain the cable tension at the proper value, and a snubber is provided to prevent the positioner from allowing the cable path to shorten under the increased tension that occurs during carriage acceleration. When the power is turned off, the cable tends to shrink due to the decreased temperature. When power is turned on, the carriage is initialized by positioning it at the left end of its range. At this position the cable tensioning mechanism can be reset to allow a shorter cable length by having an extension of the carriage disengage the snubber, allowing the positioning mechanism to reset itself to a shorter cable length.
