Abstract: A interconnection of the jaw, wedge and operating handle in a fifth wheel facilitates the provision of an indicator on a secondary locking mechanism which further insures the security of the system. In the invention, the jaw is connected to the operating handle by a pivoting timing lever which pivots off a pin on the jaw such that the jaw remains engaged with the fifth wheel until the wedge is substantially removed from engagement with the jaw. In cooperation with the primary locking mechanism, a secondary lock is provided at the end of the operating handle such that a pawl arrangement engages a stop on the fifth wheel assembly until positively released by the operator. The pawl arrangement further has a mechanical indicator which extends beyond the fifth wheel assembly and allows the operator to determine whether the king pin is engaged and the secondary lock is activated.

Abstract: A pull handle for a fifth wheel utilizes a sliding connection to the operating handle of the locking jaw of the fifth wheel. A retractor spring biases the pull handle inwardly along the sliding connection such that the pull handle assumes a position which will not engage the tires of the tractor with the lock mechanism open, regardless of the adjustment of the suspension of the tractor.
