Shotgun barrel retainer in which the barrel is pivotable about a hinge pin supported by the laterally spaced arm portions of the gun frame by means of a depending barrel lug disposed between the arms of the frame and having a semi-cylindrical recess engaged with the forward portion of the hinge pin. A coil spring urges the barrel outwardly to maintain the barrel lug firmly engaged with the hinge pin having at one end a shoe or saddle member engaged with the cylindrical surface of the hinge pin o...

A firearm of the break-open and take-down type has a frame, at least one barrel releasably mounted on the frame, and a fore end assembly releasably secured to the underside of the barrel. The fore end assembly comprises a wooden fore end stock having a channel-shaped transverse cross-section, a metal latch plate removably secured to the bottom wall of the fore end stock, and latch means mounted on the latch plate for releasably securing the fore end assembly to the underside of the barrel. The l...

A barrel box integral with the barrel rear end, with a hinge and latch for closing with respect to a fork integral with the front end of a pressure chamber. The box being connected to a mechanism of levers for compressing a plunger of the pressure chamber, the fork including an internal fork part obtained by molding, which concentrates most of the complex configurations, tightly fit and joined to a portion of a the mouth of the pressure chamber, which is of metal tube and tightly covers the whol...

A folding firearm comprises a stock supporting a receiver, the receiver defining a bore for receiving a first end of the firearm barrel. A forearm is operably pivotally connected to the stock. The forearm includes a barrel securing mechanism having a securement member. The firearm barrel has a surface adjacent to the first end for engaging the securement member. The securement member is matingly engageable with the surface of the barrel. The securement member, in response to pivotal movement by ...

A hinge device for break-open type firearm comprises two pair of arcuate ridges on the breech slidably received in complementary grooves formed in parallel sidewalls of a receiver. One pair of ridges and complementary grooves is located forwardly of the hinge axis, with one ridge and its associated groove on each side of the ridge, and the other pair of the ridges and complementary grooves is located rearwardly of the hinge axis. In the closed position of the firearm, the ridges and grooves are ...

A new double barrel shotgun for increasing firing capacity and allowing simultaneous pump action of both forearm members or independent operation of one firing mechanism if one barrel becomes unusable due to jamming. The inventive device includes a receiver with a pair of elongate spaced apart barrels coupled at their rear ends to the front end of the receiver. A pair of spaced apart elongate magazine tubes are also coupled at their rear ends to the receiver front end. A pair of spaced apart for...

A tensioning device used for achieving mass-production interchangeability of the barrels for a shotgun with articulated barrels is positioned between the barrels and the breech of the gun and comprises a rod-shaped element constituted by a fixed portion and a movable portion guided for moving on the fixed portion and subject to the action of a powerful spring which urges it against a tenon. Means are provided for adjustably engaging the rod-shaped element on the tenon.

A latching mechanism for engaging and disengaging a fore-end stock to and from a barrel assembly of a firearm. The mechanism features a unique sliding finger-operated integral latch and lever assembly which releases the fore-end stock from the barrel. The locking latch slides into snap-action engagement with a rail extending from the barrel assembly. The rail comprises a novel inclined plane which enhances the lock-up of the latch. This latching arrangement provides continuous fit even after ext...

A folding stock includes a butt plate that assumes its operational orientation in both the extended and the folded positions of the stock. A pivot arm is pivotably mounted on a mount that is adjustably inserted into recesses in the rear of the receiver of the weapon. The pivot arm pivots about the mount pivot axis at its one end and has a butt member pivotably mounted at its other end. The butt member has a horizontal stock portion and a vertical butt-plate portion at the rear. A spring fastened...

An over-and-under shotgun apparatus includes a radius track which serves as a hinge for articulating the barrel portion of the shotgun apparatus relative to the receiver/stock portion of the shotgun apparatus. The radius track is defined by a female or concave portion formed on the monoblock attached to the shotgun barrels, and a male or convex portion formed on the frame or receiver section. The radius track defines a pivot axis that is spaced from the radius track. The radius track provides a ...
