Filed:

Aug 6, 2007

Appl. No.:

11/834482

Inventors:

John Paul McCarty - Greeley CO, US

Assignee:

Burris Corporation - Greeley CO

International Classification:

F41G 1/38

US Classification:

42125, 42119, 42129, 359600

Abstract:

An eyepiece of a firearm scope includes a spring positioned between a shock mount and an ocular lens, wherein the spring holds the ocular lens a predetermined position from an objective lens of the scope when the spring is in an uncompressed state. During recoil of the firearm, the spring compresses to allow the ocular lens to travel towards the objective lens, thereby increasing an effective eye clearance distance between the ocular lens and a shooter. Following recoil, the spring expands to return the ocular lens to the predetermined position. The spring compresses again during impact of the eyepiece with the shooter's face, thereby partially absorbing the force of the impact and reducing the chance of injury to the shooter.

13/481045

Inventors:

John McCarty - Greeley CO, US

Douglas F. Paterson - Windsor CO, US

International Classification:

G06F 19/00
G01N 21/41

US Classification:

235404, 356124

Abstract:

A method is used to determine an aiming point for a sighting system used by a shooter to shoot a target. The method includes receiving a range signal that corresponds to a distance from the shooter to the target. A first position signal is received from a magnification system sensor. A first magnification setting based at least in part on the first position signal is then determined. Thereafter, a first aiming point based at least in part on both of the range signal and the first magnification setting is determined.

International Classification:

F41G 138

US Classification:

33246

Abstract:

A telescope inner tube locking device and method for positively locking the telescope inner tube in it's previously aligned position. The locking is accomplished by using a biased locking screw which operates to apply a force against the inner tube of the telescope while the windage and elevation adjustment screws on the telescope are moved. Thereafter, the biased locking screw locks the inner tube against the windage and elevation adjustment screws. In a modification of the preferred embodiment, the inner tube of the telescope may also be locked by using a locking screw constructed similarly to the elevation or windage screws in combination with a separate spring bias. The separate spring bias will apply a force against the windage and elevation screws of the telescope and the locking screw will lock the inner tube in place. The tube may also be locked by a third locking screw without using a bias. The methods disclosed herein use the applicant's invention to positively lock the inner tube in it's desired aligned position so that an accidental dropping or jarring of the firearm or heavy recoils of the firearm will not result in a misalignment of the previously aligned inner tube of the telescope.

International Classification:

US Classification:

224150

Abstract:

A retractable carrying device that effectively positions an object snugly against a user's body allowing the user to carry the object from their shoulder for long periods of time without stress and irritation. The retractable carrying device maintains tension on receiving means thereby preventing undesirable noise, and also automatically and tensionally adjusts when the retractable carrying device is utilized as a stabilizing aid. The retractable carrying device is constructed with a first elongated flexible securing means, a second elongated flexible securing means, and a retractable mechanism, the retractable mechanism being enveloped by shielding means. The retractable mechanism has elastic properties and is of the type that can be stretched or extended when an opposing directional force is applied to the retractable mechanism, thereby increasing the effective length of the retractable mechanism, and which will then return or retract to its original length when the opposing directional force is released. Flexible elongated friction reducing means provide a smooth, low friction surface against which the retractable mechanism can easily slide when the retracting mechanism operates, ensuring free movement of the retracting mechanism within the shielding means. A constant re-adjusting effect is created when the retractable carrying device is in use.

Abstract:

The present invention relates to improvements in a power rifle scope of the type having a tubular housing barrel with enlarged end portions and an optical axis defined by an optical system including an objective lens disposed in the enlarged front end thereof, an eyepiece lens system disposed in the enlarged other end thereof and an erector lens system intermediate the said two ends and where the improvement comprises the addition of a variable optical aperture mounted in and carried by a cylindrical guide tube which is secured interiorly of the scope barrel, a helically rotatable setting ring carried by and disposed exteriorly of the barrel and having an inwardly radially directed actuating pin which passes through the barrel and through a circumferential slot in the guide tube and operatively engages the variable aperture device to vary the light passing capacity of the barrel in response to rotation of the setting ring and sealing rings disposed between the setting ring and the barrel, for and aft of the actuating pin.
