ABSTRACT:
There is provided a mechanized device having the same basic uses as a turnbuckle and herein referred to as an automatic turnbuckle. The automatic turnbuckle of the present invention is designed to mechanically remove slack from a line and to keep a constant tension on a line. The structure of the present invention includes two protruding rods, one at either end of an elongated body which houses the mechanism. The exposed ends of the rods are looped. In the housing, the rods move parallel to each other and are connected by a spring and gear arrangement which allows manual movement of one of the rods in two directions and mechanical movement in one direction. There is a means included in the device for adjusting the movable rod to various pull lengths and for manually triggering a pulling action. The same means can be used to lock the rods into a fixed position,.
