  • Patent number: 4940324
    Abstract: An electronic sight having a horizontal field of view greater than the vertical field of view. The electronic sight is mounted to pivot about two axes to provide windage and elevational adjustment. A windage adjustment screw includes a windage adjustment disk that extends from a base slot into a sight tube slot. The slot in the base is elongated in a first direction and the slot in the sight tube is elongated in a second transverse direction. Rotating the windage adjustment screw moves the windage disk to cause the sight tube to pivot about a vertical axis. An elevation jack raises and lowers the sight tube to pivot the sight tube about a horizontal axis. The sight tube has a raised rail on the top that acts as a key for aid in attaching and adjusting the battery assembly and light source relative to the sight tube lens. The sight tube includes grooves on an inner surface to aid in reducing the effect of glare from ambient light.

  • Patent number: 4890407
    Abstract: A two-piece dovetail mount for a firearm formed with a vertical centerline split. The mount includes first and second members that are fastened together by threaded fasteners. The upper region of the mount forms an industry standard dovetail mount for a sight. The lower region of the mount provides a clamping region for holding the mount onto the firearm. The two members of the mount contact the firearm at the lower region and contact each other at the upper region when being fastened together by the threaded fasteners to define a downwardly opening gap therebetween. When the mount is tightly clamped onto the firearm, the gap remains between the two members at the bottom region, just above the firearm. The gap ensures that an adequate clamping force is applied to hold the mount onto the firearm and permits the mount to be further tightened after the firearm has been fired a number of times.
