ABSTRACT:
A draw spring linkage includes a hollow rod formed with a shoulder structure at the first end of the rod and with a slot that extends longitudinally of the rod and is located between the shoulder structure and the second end of the hollow rod. A tongue member includes an attachment portion and a stem that projects from the attachment portion. The stem fits slidingly in the interior space of the hollow rod and is formed with a slot that is aligned with the slot in the hollow rod. A key extends through the slot in the tongue member and the slot in the hollow rod and projects laterally from the hollow rod. A hollow cylindrical spring is threaded by the hollow rod. The first end of the spring engages the shoulder structure, the second end of the spring engages the key, and the spring is held under compression between the shoulder structure and the key.
