Definitions

  • the present invention relates to a high-precision single-shot rifle, i.e. it allows a single shot per charge, the ammunition used having a metal casing, which can be applied in the arms industry, in which the unlocking and loading operations are performed manually by a lever, allowing quickly and easily changing the barrel of the rifle, which makes it easier to perform rifle maintenance and cleaning operations in addition to the great versatility this entails by allowing the use of different barrels and different calibers with the same rifle.
  • Traditional breech-loading single shot rifles consists in the combination, in a breech-loading firearm, with the barrel thereof, of a breech-block having sliding interlocking movement upon the butt-end of the barrel, which is adapted thereto, a hammer pivoted in the said block, a trigger also pivoted in the block, and depending therefrom, and adapted to co-act with the said hammer, and a spring for actuating the breech-block in its upward movement.
  • This gun has a barrel, a stock, constructed with a chamber, and a guard plate, attached at its rear end to the stock.
  • the butt-end of the gun barrel is constructed with two corresponding transverse grooves, inclined forward from the vertical.
  • the gun further comprises a breech-block, constructed with a recess or chamber, being constructed with two inclined flanges, thus, the breech-block is adapted to have inclined sliding interlocking movement upon the butt-end of the gun-barrel.
  • the breech-block is supported by the bearing of its upper end upon the gun-barrel, and the bearing of its lower end against the walls of an opening, formed in the guard, and through which it passes. Thus, the block is locked or retained in its open position against the tension of its main-spring.
  • a hammer is hung on a pivot mounted in the breech-block.
  • a trigger hung on a horizontal pivot, mounted in te lower end of the breech-block.
  • the main-spring has the two-fold function of closing the breech-block and maintaining the same in tis closed position, and of operating the hammer in firing the cartridge in the gun.
  • the barrel is connected or fastened to the bolt by means of threading or other similar means preventing the user from being able to separate the barrel and the bolt, having to use the services of a gunsmith due to the complexity and specific tools required for the assembly and disassembly operations.
  • Some of the rifles mentioned in the preceding paragraph correspond to percussion rifles, such as, for example, the Sharps rifle, comprising mechanisms referred to as side-hammer or Sharps-Borchardt, or the rifle corresponding to the manufacturer Marlin, specifically the Ballard rifle model, as well as the coil spring-type Winchester rifle, such as the Low-wall Musket model.
  • percussion rifles such as, for example, the Sharps rifle, comprising mechanisms referred to as side-hammer or Sharps-Borchardt, or the rifle corresponding to the manufacturer Marlin, specifically the Ballard rifle model, as well as the coil spring-type Winchester rifle, such as the Low-wall Musket model.
  • the firing pin perforates the primer when firing, causing a high-pressure backfire towards the shooter through the firing pin passage, specifically towards the shooter's face and eyes, with the subsequent risk of a serious accident that this entails.
  • the present invention relates to a single-shot rifle according to claim 1.
  • An optimal contact surface for contact between bolt and barrel is thus provided.
  • the attachment between bolt and barrel is obtained without involving the receiver, which represents a difference with regard to many conventional systems.
  • the receiver therefore does not have to withstand the pressure and strain produced on the bolt at the moment of firing, from inside the chamber. This enables, for example, manufacturing the receiver with light alloy materials without reducing the strength of the assembly.
  • it is very easy to disassemble the bolt with regard to the barrel, for example, for cleaning it, and it is also easy to later assemble the bolt.
  • the central supporting element of the rifle is the receiver, on which the barrel is borne, supported or held, which barrel, according to a preferred embodiment, is assembled to a solid element or part referred to as monobloc, with the cooperation of a cotter pin and a pair of anchoring screws attaching the solid element or monobloc to the receiver.
  • the firing mechanisms and safety means, as well as the stock of the weapon, are also assembled in the receiver.
  • the fixing means comprise a cotter pin, for the purpose of assuring that the position of the barrel with regard to the receiver is always the same, also obtaining precise sliding between the bolt and the barrel.

  • the bolt is arranged adjacent to the barrel, inside which the firing pin is housed, which firing pin is operated by a spring, in a back area of the bolt, i.e. in an area opposite to the barrel.
  • the stock is located in the back part of the rifle, behind the receiver, and it can have a wide variety of configurations and materials, which can be changed and combined with the rest of the elements of the rifle by means of connecting them to the receiver, for example, by means of a clamping screw.
  • the bolt of the rifle proposed by the invention has at least one channel configured to slide on the actual barrel, said bolt being firmly fastened to the barrel.
  • the locking system having two or more rows of engaging channels and ribs is contemplated, although with a single row the locking system provides an optimal contact surface, several times greater than the contact surface for fastening said elements in any conventional rifle the bolt of which comprises traditional bolt lugs .
  • the receiver, stock, lever and remaining mechanism assembly forms a module configured to be coupled or connected to barrels of different types, configurations and calibers, whereby providing a highly versatile rifle which enables its use, in a quick and easy manner, with barrels of different calibers.
  • said at least one rib comprises at least one rib located at the back end of the barrel, and in which said at least one channel comprises at least one channel located in the bolt and configured to receive said at least one rib, such that with said at least one rib housed in said at least one channel the bolt is attached to the barrel such that it cannot travel backwards with regard to the barrel, but such that it can travel in a direction substantially perpendicular to the barrel, by means of sliding said at least one rib in said at least one channel.
  • said at least one rib comprises at least two ribs, and said at least one channel comprises at least two channels.
  • said at least one rib extends around at least part of the circumference of the barrel, in correspondence with the back end of the barrel.

  • said solid element is traditionally fixed to the barrel by means of a recess at the back end of the barrel, for the purpose of introducing it in a longitudinal hole of said solid element.
  • Both parts are fastened together by means of silver welding which occasionally fails either because of an incorrect application, due to the deterioration caused over time or due to the use of the weapon, causing serious drawbacks, such as the barrel flying off, with the subsequent risk of an accident, in addition to said silver welding requiring being applied in a very precise manner because otherwise there will be porosities which, upon bluing the barrel, allow the penetration of bluing salts which will ooze out, causing an unpleasant and dirty appearance.
  • the barrel of the rifle proposed by the invention is configured to be frontally introduced in the solid element.
  • the barrel comprises at least one flange, close to the rib, used as a stop limiting the forward exit of the barrel with regard to the solid element.

  • the barrel fits into a channel existing for that purpose in the solid element or monobloc.
  • the attachment between the receiver and the barrel is strengthened by means of the screws, such that by simply loosening said screws the barrel is easily separated from the receiver, which then enables separating the barrel from the bolt.
  • the rifle comprises a handguard, an element also known as a crossguard or crosstree, attached to the barrel by means of a pin threaded into the solid element and substantially extending parallel to the barrel, the pin having a substantially conical surface which is introduced in a clip in which the pin is held by means of a screw.
  • the handguard also referred to as crosstree or crossguard, is located in the distal part of the rifle, i.e. in the part corresponding to the barrel, which is not fixed or fastened to the barrel, but rather is fixed to the solid element or monobloc by means of a pin which, at its end part, has a conical area configured to receive the action of a screw which is contained in the clip, which is in turn firmly fastened to the handguard.
  • the rifle comprises at least one lever pivotable about an axis, being said lever coupled to the bolt for its operation, such that when the lever pivots in a first direction, said lever moves the bolt towards the loading position, and when the lever pivots in un second direction opposite to the first direction, the lever moves the bolt towards the firing position.
  • the rifle For the purpose of allowing the unlocking and the locking of the bolt, the rifle comprises a lever configured to rotate with regard to an axis.
  • the lever has a latch that swings on an axis for its unlocking and its fixing, or immobilization, said latch being configured to engage in a pin fixed to the receiver for fixing the lever.
  • the latch has a spring which at one end is fixed to the lever by means of a pin.
  • the run of said latch is limited by another pin.

  • an attachment element which can consist of a chain or connecting rod, having two axes, on one hand an axis hinged to the bolt and on the other hand an axis hinged to the lever.
  • the lever is associated to an extractor configured for extracting the cartridge cases, such that when said lever pivots in said first direction, said lever makes said extractor slide backwards, so that it causes the extraction of a cartridge case.
  • the lever is associated to said extractor by means of a pivotable arm, or extraction lever, meshing with the extractor and configured such that it follows the movement of the lever during at least part of the run of the lever between the loading position and the firing position of the bolt.
  • the pivotable arm is useful to transmit the movement of the lever to the extractor, such that the pivotable movement of the lever is converted into a linear movement of the extractor during part of the run of the lever.
  • the lever In addition to the function of unlocking the bolt, the lever thus has other additional functions.
  • the first of said additional functions consists of producing or causing the ejection or extraction of the fired ammunition cartridge cases from the chamber of the barrel.
  • the lever has a bushing concentric to its axis configured to allow the rotation of the pivotable arm, also referred to as extraction lever, which is in turn configured to convert the rotational movement of the lever into a translational or sliding movement of the extractor.
  • the extraction system comprises a linear extractor located under the chamber of the rifle, said extractor being configured to mesh with the pivotable arm, in the same way a rack and pinion mechanism meshes.
  • the lever houses a part which, at the same time as that which is described above, receives the action or thrust of the spring, such that said part penetrates a small cavity located under the pivotable arm, achieving that the lever and the pivotable arm are temporarily attached or connected.
  • the rotational movement of the pivotable arm acts by making the extractor slide backwards, causing the extraction of the used ammunition metal casing or cartridge case which is housed in the barrel.
  • the extractor is provided with a cartridge case extraction pin, which pin is housed in said extractor and is pressed on by a spring, said pin being configured to slide in a groove in the barrel during at least part of the run of the extractor, and to mesh with a used cartridge case for its extraction from the chamber.
  • the back part of the extractor has a pin acted or pressed on by the spring, engaging in an extraction groove of the back part of the used ammunition cartridge case.
  • the rifle comprises a sear element pushed by a sear spring towards a position in which it engages a trigger, as well as a safety element that can travel between a position in which it prevents the firing of the rifle and another position in which it does not prevent the firing of the rifle, the safety element being drawn towards the position in which it prevents the firing of the rifle by a safety spring, the safety element and the sear element being arranged such that when the bolt travels towards the loading position, the sear element pushed by the sear spring is moved, allowing the safety element to travel to the position in which it prevents the firing of the rifle.
  • a second additional function of the lever is to automatically cock, activate or load the percussion means or system.
  • the sear element moves and drops down, acted on or driven by the sear spring.
  • the safety element is released and automatically flies out backwards due to the effect or the actuation of the safety spring, the action of which is opposite to the action of the sear spring, such that the rifle is in a safety or locked position.
  • the safety element which can consist of a knurled lever, is located on the receiver of the rifle in an easy access position for the thumb of the hand the user is firing with, enabling ambidextrous use.
  • Said safety element is configured to be placed, or activated, and removed, or deactivated, by the user, having the particularity that said safety element is always automatically located in the active position when the bolt is unlocked to load or unload the weapon, preventing in said active safety position the firing of the rifle.
  • the safety element has a safety spring which pulls on said safety element as soon as the sear element is released from the hammer, i.e. when the lever is lowered. Therefore, when said lever moves up, for the purpose of compressing the percussion spring, the safety element is already acting, i.e. it is already activated. In short, in order to fire it is always necessary for the user to voluntarily remove the safety, placing it in the inactive position.
  • the rifle comprises a highly sensitive trigger provided with dual-regulation.
  • the trigger has, in its lower part, an adjusting screw which, by means of tightening it, achieves that the trigger recoils, therefore the engagement of the upper area with the sear element is reduced, and therefore the trigger is attenuated.
  • the rifle has the end stop adjusting screw, which runs inside the trigger spring, which decreases or reduces the run of the trigger by means of tightening it.
  • the sear element is arranged such that when the bolt travels towards its loading position, the sear element engages with the trigger.

  • the hammer is located inside the bolt and is configured to strike the firing pin, such that said firing pin in turn acts on an ammunition percussion cap causing its detonation.
  • the hammer is linked to the sear element such that is retained by the sear element when the bolt travels from the loading position towards the firing position is contemplated, such that when the bolt reaches the firing position, the hammer is cocked to be fired towards the firing pin.
  • the single-shot rifle described above can also comprise a fire protection element, associated to the bolt and configured to impede a possible backfire from injuring the user.
  • the bolt is locked with the fire protection element, also referred to as a safety deflector, which consists of a steel part which is fastened to the bolt by a screw.
  • the lower part of the bolt has the hammer, which is configured to rotate with regard to a hammer axis and be acted on by a main spring.

  • the back part of said extractor (17) has a pin (18) acted or pressed on by the spring (56), engaging in an extraction groove of the back part of the used ammunition cartridge case.
  • the rifle comprises a sear element (13) pushed by a sear spring (30) towards a position in which it engages a trigger (14), as well as a safety element (16) that can travel between a position in which it prevents the firing of the rifle and another position in which it does not prevent the firing of the rifle, the safety element (16) being drawn towards the position in which it prevents the firing of the rifle by a safety spring (26), the safety element (16) and the sear element (13) being arranged such that when the bolt (8) travels towards the loading position, the sear element (13) pushed by the sear spring (30) is moved, is moved, allowing the safety element (16) to travel to the position in which it prevents the firing of the rifle.
  • a second additional function of the lever (10) is to automatically cock, activate or load the percussion means or system.
  • the sear element (13) moves and drops down, acted on or driven by the sear spring (30).
  • the safety element (16) is released and automatically flies out backwards due to the effect or the actuation of the safety spring (26), the action of which is opposite to the action of the sear spring (30), such that the rifle is in a safety or locked position, position which is shown in Figure 8 .
  • the safety element (16) is located on the receiver (1) of the rifle in an easy access position for the thumb of the hand the user is firing with, enabling ambidextrous use.
  • Said safety element (16) is configured to be placed, or activated, and removed, or deactivated, by the user, having the particularity that said safety element (16) is always automatically located in the active position when the bolt (8) is unlocked to load or unload the weapon, preventing in said active safety position the firing of the rifle.
  • the safety element (16) has a safety spring (26) which pulls on said safety element (16) as soon as the sear element (13) is released from the hammer (12), i.e. when the lever (10) is lowered. Therefore, when said lever (10) moves up for the purpose of compressing the percussion spring (27), the safety element (16) is already acting, i.e. it is already activated, as can be seen in Figures 6 and 8 . In short, in order to fire it is always necessary for the user to voluntarily remove the safety, placing it in the inactive position, as shown in Figures 9 and 2 .
  • the rifle comprises a highly sensitive trigger (14) provided with dual-regulation.
  • the lower part of the trigger (14) has an adjusting screw (50) which, by means of tightening it, achieves that the trigger (14) recoils, therefore the engagement of the upper area with the sear element (13) is reduced, and therefore the trigger is attenuated.
  • the rifle has the end stop adjusting screw (59), which runs inside the trigger spring, which decreases or reduces the run of the trigger (14) by means of tightening it.
  • the sear element (13) is arranged such that when the bolt (8) travels towards its loading position, the sear element (13) engages with the trigger (14).
  • the rifle comprises a hammer (12) configured to strike the firing pin (24) when the trigger (14) is squeezed with the safety element (16) in the position in which it does not prevent the firing of the rifle, the hammer (12) being pivotably attached to the bolt (8) such that it travels with the bolt (8) when the bolt (8) travels between the firing position and the loading position.
  • the hammer (12) is located inside the bolt (8) and is configured to strike the firing pin (24), such that said firing pin (24) in turn acts on an ammunition percussion cap causing its detonation.
  • the hammer (12) is linked to the sear element (13) such that is retained by the sear element (13) when the bolt (8) travels from the loading position towards the firing position, such that when the bolt (8) reaches the firing position, the hammer (12) is cocked to be fired towards the firing pin (24).
  • the single-shot rifle also comprises a fire protection element (9) associated to the bolt (8) and configured to deflect sparks coming out backwards at the moment of firing.
  • the bolt (8) is locked with the fire protection element (9), also referred to as safety deflector, consisting of a steel part which is fastened to the bolt (8) by a screw (34).
  • the bolt (8) internally has the hammer (12) which is configured to rotate with regard to an axis (51) of hammer (12) and to be actuated by a main spring (28) as can be seen, for example, in Figure 2 .
  • the firing pin (24) perforates the primer when firing, causing a high-pressure backfire towards the shooter through the firing pin passage, specifically towards the shooter's face and eyes, with the subsequent risk of a serious accident that this entails.
  • the rifle comprises a fire protection element (9), i.e. a safety deflector consisting of a steel part firmly fastened to the bolt (8), said fire protection element (9) being configured to deflect the backfire occurring when firing towards inner areas, with lower exhaust, of the receiver (1), making said bolt (8) lose pressure and thus preventing the previously discussed accidents.
  • a fire protection element (9) i.e. a safety deflector consisting of a steel part firmly fastened to the bolt (8), said fire protection element (9) being configured to deflect the backfire occurring when firing towards inner areas, with lower exhaust, of the receiver (1), making said bolt (8) lose pressure and thus preventing the previously discussed accidents.
  • the fire protection element (9) comprises a deflection surface, configured to deflect sparks towards the inside of the receiver (1), preventing them from reaching the user's eyes.
  • Said deflection surface is preferably configured such that it forms, in the vertical plane traversing the barrel (6) when the rifle is in a conventional use position, an angle of approximately 45 degrees with the longitudinal direction in which the barrel (6) extends.
  • the fire protection element (9) comprises an inclined plane, preferably occupying a 45° inclination when the rifle is in a firing position, which is located opposite to the passage of the firing pin (24), such that by means of this arrangement the sparks bounce off and are guided downwards, avoiding striking the face of the user of the rifle.
