Abstract

A double-barreled drop-down sporting gun including means for locking the barrel in its closed condition by means of pins carried by the barrel and engaging the remaining barreled section of the gun upon operation of a toggle lever which is locked in its barrel unlocking position as long as the barrel is open. The gun is furthermore provided with means through which the trigger controlling the firing through one barrel is mechanically connected with the triggering means for the other barrel in such a manner that after firing one shot through one barrel the marksman may actuate the same trigger again so as to fire through the other barrel.

Claims

1. In a double-barrelled drop down sporting gun including a barrel and a barrelled section pivotally secured together, the provision of a barrel-locking mechanism comprising two cylindrical locking pins parallel with the barrel axes when the barrel is in its closed position and adapted to slide along the direction of their axes between an unlocking position inside the barrel and a projecting position in which they engage the rear end of the barrelled section of the gun, a plate parallel with the plane of the pins axes and provided with two transverse projections engaging permanently the corresponding locking pins, said plate being adapted to slide in its plane to shift said pins between their two aforesaid positions, means controlling the movements of said plate and thereby those of the locking pins, a toggle lever controlling said last-naMed means, said platecontrolling means including a rotary ring lying in a plane parallel with said plate, said ring including an eccentric stud which engages a transverse slot in said plate and a further stud facing away from the plate and engaged by the toggle lever, the angular movement of said toggle lever causing said further stud to make the ring rotate and thereby shift the plate longitudinally, a projection of said toggle lever holding said ring axially and engaging a longitudinal slot on the plate, and further means guiding the plate longitudinally in parallelism with the axis of the locking pins.

2. In a double-barrelled drop down sporting gun, including a barrel and a barrelled section pivotally secured together, the provision of a barrel-locking mechanism comprising two cylindrical locking pins parallel with the barrel axes when the barrel is in its closed position and adapted to slide along the direction of their axes between an unlocking position inside the barrel and a projecting position in which they engage the rear end of the barrelled section of the gun, a plate parallel with the plane of the pin axes, provided with two transverse projections engaging permanently the corresponding locking pins and adapted to slide in its plane to shift said pins between their two aforesaid positions, means controlling the movements of said plate and thereby those of the locking pins, a toggle lever controlling said last-named means, the barrel being provided with a bore extending through it in parallelism with the locking pins, the plate-controlling means including a rotary ring lying in a plane parallel with said plate and including an eccentric stud engaging a transverse slot in the plate and a further stud facing away from the plate and engaged by the toggle lever, the angular movement of which causing said further stud to make the ring rotate and thereby shift the plate longitudinally, a projection on the toggle lever holding the ring axially and engaging a longitudinal slot in the plate, further guiding means guiding longitudinally the plate in parallelism with the axes of the locking pins, said mechanism including furthermore an arrangement holding the toggle lever in its position corresponding to the unlocked position of the pins and including a section of the toggle lever facing the rear end of the barrel, a further pin adapted to slide obliquely on the surface of said latter section of the toggle lever and registering with the rear end of the first bore when the toggle lever is in the position corresponding to the unlocked position of the locking pins, a spring urging said further pin outwardly of the toggle lever into said first bore for said position of the toggle lever, a pusher rod slidingly carried by said bore and urged outwardly to the front of the barrel upon engagement of said further pin into said first bore, said pusher rod being pushed back into said first bore by the barrelled section of the gun to thereby shift said further pin back into the toggle lever and release the latter.

3. In a double-barrelled drop down sporting gun including a barrel and a barrelled section pivotally secured together, the provision of a barrel-locking mechanism comprising two cylindrical locking pins parallel with the barrel axes when the barrel is in its closed position and adapted to slide along the direction of their axes between an unlocking position inside the barrel and a projecting position in which they engage the rear end of the barrelled section of the gun, a plate parallel with the plane of the pin axes, provided with two transverse projections engaging permanently the corresponding locking pins and adapted to slide in its plane to shift said pins between their two said positions, means controlling the movements of said plate and thereby those of the locking pins, a toggle lever controlling said last named means, the barrel being provided with a bore extending through it in parallelism with the locking pins and being further provided with an oblique blind bore opeNing rearwardly towards the toggle lever, the plate-controlling means including a rotary ring lying in a plane parallel with said plate and including an eccentric stud engaging a transverse slot in the plate and a further stud facing away from the plate and engaged by the toggle lever and the angular movement of which causes said further stud to make the ring rotate and thereby shift the plate longitudinally, a projection on the toggle lever holding the ring axially and engaging a longitudinal slot in the plate, further means guiding longitudinally the plate in parallelism with the axes of the locking pins, said mechanism including furthermore an arrangement holding the toggle lever in its position corresponding to the unlocked position of the pins and including a section of the toggle lever facing the rear end of the barrel, a further pin adapted to slide obliquely on the surface of said section of the toggle lever facing the rear end of the barrel and registering with the rear end of the first bore when the toggle lever is in the position corresponding to the unlocked position of the locking pins, a spring urging said further pin outwardly of the toggle lever into said first bore for said last named position of the toggle lever, a pusher rod slidingly carried by said bore and urged outwardly to the front of the barrel upon engagement of the further pin inside said first bore, said pusher rod being pushed back into said first bore by the barrelled section of the gun to thereby shift the further pin back into the toggle lever and release the latter, another stud slidingly carried by the oblique bore in the barrel, a coil spring urging said other stud towards the toggle lever and a cam-shaped section incorporated with the toggle lever and engaged by the stud when the toggle lever is in the released position, to urge it into its opposite position.
