Abstract

Abstract A device for opening and closing a gate comprising a normally closed latch means at the free end of the gate and a spring means at the other end of the gate for returning the gate to its closed position. One form of the latch means comprising a latching arm which is pivotally secured to the post adjacent the free end of the gate and which may be moved between locked and unlocked positions. A bar means extends from the free end of the gate for engagement with the latching member to maintain the gate in its closed position. An elongated flexible cable is secured to the latching member and extends upwardly therefrom to a location adjacent the approach area of the gate to permit a person on a tractor or the like to grasp the cable and to move the latching member to its unlocked position. The tractor is then driven against the gate which causes the gate to swing open as the tractor is driven thereby. Once the tractor has disengaged from the gate, the spring means causes the gate to return to its closed position. The modified form of the latch means comprises a spring loaded plunger element which is secured to the free end of the gate and which is received by an opening in a bracket secured to a post adjacent the free end of the gate.
