  • Patent number: 7444714
    Abstract: A ranch gate arm assembly which incorporates a gate arm that is mounted to allow swivelling about a longitudinal pivot when an external man or machine force is applied to either side of the gate arm thereby inducing the gate arm to swing out, and two torsion springs, one assembled on each side of the ranch gate arm which push against correlating sides of the gate and push the gate back to a center position after the external force has passed completely through the opening. This gate arm assembly is equipped with a smoothing release assembly, which eliminates the jolt force caused by the quick returning of the gate assembly to the center position that the gate was originally in before the external force was applied.

  • Patent number: 7325842
    Abstract: An automatic gate closer latch for use in centrally securing a commercial or industrial swinging gate to a stationary fence post, especially useful in the farming and ranching applications, includes a gate catcher assembly mounted on a swivel bolt, complete with directional pressure finders, a bearing tensioner assembly consisting of a bearing tensioner plate, a roller bearing, a tension spring and mounting hardware. The said gate latch catcher assembly is a flat bar segment composed of three right angled bends designed similar to open fingers, to catch the oncoming protruded gate edge post. The directional pressure fingers incorporated in the opposite ends of the gate catcher finger assembly allows the spring tension assembly to maximize its distance in the central neutral position thus causing an automatic closed latch phenomenon. Above normal pressure from an implement on either side of the gate will promote the fingers to open allowing the gate to swing open.
