Abstract:
The method for the manufacture of a turnbuckle formed of complementary right and left split shaft members, each bearing a section of helical threads of opposite direction to the threads of the other which comprises:a. cutting complementary right and left threaded sections on cylindrical shafts of equal diameter;b. machining each of said right and left cylindrical shafts to split each longitudinally along said threaded sections to form longitudinally split shaft members having right and left directional helical threads;c. pairing one each of split shaft members with another having opposite directional helical threads;d. placing a separation band selected from low frictional characteristic plastics or corrosion resistant metals between the mating surfaces of said split shaft members; ande. joining said split shaft members with a nut remember having complementary internal right and left directional threads.
