Filed:

Feb 28, 2007

Appl. No.:

11/713308

Inventors:

Daniel R. Shepherd - Waterloo NE, US

International Classification:

F41G 1/38

US Classification:

42130, 42119, 42122, 89 4119

Abstract:

An improved telescopic gun sight includes a telescopic gun sight at least including an adjustable lens configuration for adjustably magnifying an external object to form an object image, an inverting tube for inverting the object image, an ocular lens array for presenting the object image for viewing, a primary reticule including sighting insignia imprinted thereon and a secondary reticule being movable both horizontally and vertically in the image plane. The secondary reticule includes a generally horizontal windage correction scale operative to provide instant windage correction target alignment. It includes instant windage correction target alignment values positioned at point-specific spaced-apart locations with specific instant windage correction target alignment values corresponding to selected distance amounts calculated for a selected bullet type and weight.

Appl. No.:

6/206668

Inventors:

Daniel R. Shepherd - Waterloo NE

International Classification:

F41G 138
F41G 142

US Classification:

33246

Abstract:

A telescopic sight including primary and secondary reticules separately disposed within separate image planes formed at respective opposite ends of an inverting tube. The secondary reticule is selectively retractable between a first position lying within the field of view of the scope and a second position lying outside the field of view of the scope. A pair of control knobs provide independent adjustability to relatively position the separate reticules with respect to the image viewed through the scope. The secondary reticule is mounted for selective presentation of one of a plurality of reticule surfaces carried by the reticule, with each reticule surface bearing engraved indicia for determining target range and for compensating for bullet drop.

Appl. No.:

9/211334

Inventors:

Thomas Jefferson Shepherd - Buckner MO
Daniel Richard Shepherd - Waterloo NE

International Classification:

A47G 2900

US Classification:

248683

Abstract:

A mount or rest for a camera, firearm, spotting scope, sextant, or other optical or aiming device comprises a magnetic base for attachment to magnetically attractable surface, such as the a surface of a vehicle, a post extending vertically from the base, a tube telescopically received within the post, and a means for mounting an aiming device comprising a stem telescopically received within the tube. In another aspect, a system for supporting an aiming device is disclosed wherein a base unit is provided that allows for the use of the magnetic stand on a nonmagnetically attractable surface.
