Winch-operated extendable tongue for boat trailers and the like

    This invention relates to a winch-actuated extendable tongue for boat trailers and the like that is characterized by the winch being so located and reaved with respect to a pair of telescoping elements that it is effective to positively drive the tongue into extended as well as retracted position regardless of whether the load thereon is such as to extend or retract same. More specifically, the winch is mounted on the outer of the two telescoping elements for movement therewith and its cable is reaved from an initial point of attachment on the inner of said telescoping elements, around the winch drum several turns, over a pulley on the end of the outer element remote from the initial point of attachment, back again toward the latter to a second pulley on the adjacent end of the outer element, around the second pulley and toward the remote end of the outer element again to a second point of attachment on the inner element.
