Sight viewing apparatus

Viewing apparatus for sighting distant targets comprising, in combination:

• a generally enclosed and elongated see-through passage allowing viewing of the target therethrough;
• means for sighting the target along a single sight line extending through the enclosed and elongated see-through passage;
• an enclosed source of light located outside the enclosed and elongated see-through passage;
• means for allowing light from the source to pass into the enclosed and elongated see-through passage and generally without direct viewing from outside of the enclosed and elongated see-through passage;
• a body portion;
• means for slideably mounting the enclosed and see-through passage to the body portion;
• means for preventing sliding of the enclosed and see-through passage relative to the body portion, with the source of light located within and enclosed by the body portion;
• and means for mounting the body portion to an apparatus such as a firearm.

In a viewing apparatus for sighting distant targets including first and second sights for sighting the target along a single sight line, with the first and second sights being spaced from each other, a device for providing elevation adjustment of the second sight relative to the first sight comprising, in combination:

• an angular surface extending at an acute angle relative to the first sight;
• a slide, with the second sight attached to the slide;
• a dove tail groove formed in and parallel to the angular surface;
• a leg formed on the slide of a shape and size complementary to and for slideable receipt in the dove tail groove;
• a bolt located in the dovetail groove and threadably received in the leg of the slide;
• and means for preventing longitudinal movement of the bolt in the dovetail groove while allowing rotation of the bolt in the dovetail groove.

Viewing apparatus for sighting distant targets comprising, in combination:

• a generally tubular portion allowing viewing of the target therethrough;
• means for sighting the target along a single sight line extending through the tubular portion, with the tubular portion having an inside surface and an outside surface;
• a body portion having an inner surface and an outer surface, with the inner surface of the body portion having a configuration generally complementary to and for nesting with a longitudinal section of the outside surface of the tubular portion;
• a longitudinally extending dove tail groove formed in one of the inner surface of the body portion and of the longitudinal section of the tubular portion;
• a longitudinally extending dove tail joint formed in the other of the inner surface of the body portion and of the longitudinal section of the tubular portion, with the dove tail joint being slideably received in the dove tail groove, with the inside surface and the outside surface of the tubular portion having a constant longitudinal size to allow extrusion of the tubular portion;
• means formed on the outer surface of the body portion for mounting the body portion to an apparatus requiring sighting such as a firearm, with the inner surface, the outer surface, and the mounting means of the body portion having a constant longitudinal size to allow extrusion of the body portion;
• and means for selectively preventing sliding of the dove tail joint in the dove tail groove.

In a viewing apparatus for sighting distant targets including first and second sights for sighting the target along a single sight line, with the first and second sights being spaced from each other, a device for providing windage adjustment of the second sight relative to the first sight comprising, in combination:

• a slide positioned relative to the first sight;
• a threaded shaft extending from the second sight;
• a bore formed in the slide for slideably receiving the threaded shaft;
• a nut for threadable receipt on the threaded shaft;
• and means for capturing the nut in the slide while allowing rotation of the nut on the threaded shaft.
