ABSTRACT:
A gut stringing device for stringing a tennis racket or the like which permits accurate adjustment of a tension applied to the string. The device has a threaded screw and a nut mounted on it. Slide plates carrying a string clamp are moved by driving the threaded screw. Simultaneously a lever coupled to the nut swings against the bias of a spring until it touches a limit switch set at a desired pound value. The limit switch stops a motor driving the threaded screw.
