Patent number: 4509577Abstract: 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.Type: GrantFiled: November 7, 1983Date of Patent: April 9, 1985Assignee: Priefert Mfg. Co., Inc.Inventor: Marvin J. Priefert

The engagement is provided by upper and lower channels provided in the respective edges of the panel which engage opposing sides of the front wall adjacent the edge of the opening. Because of the generally unsupported and flexible nature of the front wall along the upper edge of the opening, the panel engaging structure includes tab portions of varying height which in certain areas snap into the respective opposing channel and at other areas require sufficient forceful displacement of the top of the wall to seat the tab in the flange so that unintended disengagement is prevented even at the most flexible area of the panel.Type: GrantFiled: February 18, 1975Date of Patent: February 10, 1976Assignee: White-Westinghouse CorporationInventor: Charles W.

Patent number: RE32934Abstract: A flexible barrier element for a passageway defined by two spaced posts is held in a raised taut position to block the passageway by placement of a hand lever having a lost motion connection with the barrier element in a level position of engagement with a bracket fixed on one post. Swinging of the hand lever to a depressed position relative to the bracket on which it is pivotally mounted slackens the flexible barrier element and lowers it to a ground level position allowing unobstructed passage between the posts defining the passageway. A second bracket on the second post has a flexible barrier element attached to it.Type: GrantFiled: June 19, 1987Date of Patent: May 30, 1989Inventor: Richard M. Baines
