Abstract
The chain gate has a pair of reversely inclined end posts which extend upwardly in a diverging relation and movably support the ends of a plurality of chain members extended therebetween. When the chain gate is in a gateway closing position the chain members are in a vertically spaced relation and in a gateway opening position the chain members form a mass on the ground surface between the end posts. The adjacent ends of the chain members are interconnected by a flexible actuating member so that on closing upward movement of the chain members from lowered ground positions the opposite ends of each chain member are concurrently moved upwardly so as to sequentially move the chain members to their horizontally extended vertically spaced relation defining the gate closing position. The chain members vary in length relative to the reversed inclination of the end posts so as to be drawn taut between the end posts in the gate closing position. The chain gate may be opened or closed either mechanically or manually.
