US12455142 - Clamping mechanism for mounting an accessory to a firearm barrel

A clamping mechanism for mounting an accessory, such as a scope, to a firearm barrel includes first and second clamp members with inner planar surfaces configured to engage respective outer surfaces of the barrel so as to distribute clamping forces evenly and minimizing damage to the barrel surface. A dovetail section on one of the clamp members enables attachment of various optics or accessories. The clamp members are secured together using one or more fasteners passing through aligned openings in the clamp members. The clamping mechanism allows non-permanent, stable mounting of accessories without requiring permanent modification to the firearm. The clamping mechanism is particularly configured to be mounted on the barrel of a Henry® brand rifle.

The patent describes a clamping mechanism designed for securely attaching accessories, like scopes, to a firearm barrel without causing permanent modifications. It features two L-shaped clamp members that distribute clamping forces evenly and allow for quick-release attachment using a removable fastener.

Claim 1

  1. A clamping mechanism for removably securing an accessory to a firearm barrel, comprising: a first clamp member having a generally L-shaped configuration defined by a first leg portion and a second leg portion extending from the first leg portion, the first clamp member including a first set of planar inner surfaces configured to engage corresponding outer surfaces of the firearm barrel, and a first exterior side surface comprising at least one threaded through-hole; and a second clamp member having a generally L-shaped configuration defined by a first leg portion and a second leg portion extending from the second leg portion, the second clamp member including a second set of planar inner surfaces configured to engage additional corresponding outer surfaces of the firearm barrel, an exterior side surface of the second leg portion comprising at least one blind threaded hole configured to be aligned with the at least one threaded through-hole of the first clamp member; wherein the first and second clamp members are removably and securely connected together using a removable fastener extending through the threaded through-hole in the first clamp member and into the blind threaded hole in the second clamp member; wherein the first set of planar inner surfaces and the second set of planar inner surfaces are collectively configured for engagement with corresponding outer surfaces of the firearm barrel, thereby distributing clamping forces and resisting rotation or slippage of the clamping mechanism during use; wherein the first and second clamp members each includes a tapered inner planar surface configured to engage and clamp opposing outer surfaces of the firearm barrel; and further comprising a quick-release capability whereby the clamp members are securable and removable using only said fastener, without requiring specialized tools; and wherein the exterior side surface of the second leg portion of the second clamp member comprises a curved outer surface configured to be aligned with, but spaced apart from, an inner curved corner surface formed at an intersection of the first and second leg portions of the first clamp member to accommodate tolerance when the clamping mechanism is mounted on the firearm barrel for removably securing an accessory to the firearm barrel. a first clamp member having a generally L-shaped configuration defined by a first leg portion and a second leg portion extending from the first leg portion, the first clamp member including a first set of planar inner surfaces configured to engage corresponding outer surfaces of the firearm barrel, and a first exterior side surface comprising at least one threaded through-hole; and a second clamp member having a generally L-shaped configuration defined by a first leg portion and a second leg portion extending from the second leg portion, the second clamp member including a second set of planar inner surfaces configured to engage additional corresponding outer surfaces of the firearm barrel, an exterior side surface of the second leg portion comprising at least one blind threaded hole configured to be aligned with the at least one threaded through-hole of the first clamp member; wherein the first and second clamp members are removably and securely connected together using a removable fastener extending through the threaded through-hole in the first clamp member and into the blind threaded hole in the second clamp member; wherein the first set of planar inner surfaces and the second set of planar inner surfaces are collectively configured for engagement with corresponding outer surfaces of the firearm barrel, thereby distributing clamping forces and resisting rotation or slippage of the clamping mechanism during use; wherein the first and second clamp members each includes a tapered inner planar surface configured to engage and clamp opposing outer surfaces of the firearm barrel; and further comprising a quick-release capability whereby the clamp members are securable and removable using only said fastener, without requiring specialized tools; and wherein the exterior side surface of the second leg portion of the second clamp member comprises a curved outer surface configured to be aligned with, but spaced apart from, an inner curved corner surface formed at an intersection of the first and second leg portions of the first clamp member to accommodate tolerance when the clamping mechanism is mounted on the firearm barrel for removably securing an accessory to the firearm barrel.
