Rifle safety for low caliber .22 cartridges and similar calibers

Abstract

This invention refers to a new safety, incorporated toward the end of the mechanism chamber of a double-shot rifle, located slightly behind the trigger, whose safety has a movement toward the back which occurs automatically upon moving the bolt handle to remove the shell or the cartridge and prepare the rifle, leaving the safety in place for its shot, and where the safety is removed manually upon moving the safety toward the front of the gun when the arm is ready for shooting. The safety is formed by a trigger safety to prevent accidental firing of the weapon and is fit to the combination of a rectangular plate in whose base there is a mechanism release window corresponding to the track of the trigger having in addition some bores in its corners in eyelet form that serve as guides for the course and movement of the trigger safety.

1 . Safety for low (0.22) and similar caliber cartridge rifles, having a cylinder at the front, followed by the mechanism chamber and the butt, comprising: 
 toward an end of the mechanism chamber, present on the upper left-hand side, a cartridge feeder where a cartridge that is inserted will be fed automatically and a second cartridge which stays in the rifle chamber in such a way that the rifle can be converted to a double-shot type or the repetition type;    where the cartridge feeder, formed by a curved plate conforming to the cylindrical curvature of the cartridge casing, a spring that stops the second cartridge so that it does not come out of place and where the bullet or pellet is fed into the chamber of the rifle upon the opening of a bolt whose function is that of introducing a cartridge into the interior of the chamber for its later detonation and at the same time of extracting the casing once it has been detonated;    said bolt being fit to a cylindrical piece which has at the end a striker, whose function is to detonate the cartridge, formed by a raised edge on its cylindrical face,    an extractor, whose function is that of extracting the shell of the detonated bullet or the cartridge at the moment said bolt is moved said bolt being formed by a protruding border on its cylindrical face besides having a bolt handle located toward the opposite end, being comprised of a cam attached so that it is perpendicular to the cylindrical piece and fixed to the cylinder, whose function will be to move the bolt in a rocking motion toward the front and the back, having in addition a small groove above the straight part of the cylinder forming the step of the release that aligns with a groove on the trigger and a V-cut at the end of the cylindrical part, which should align with a hammer, whose function is to hit the perforator that is inside the bolt, and this, in turn, impact the cartridge;    said hammer being a hollow cylindrical piece forming a ring with walls at only one end and having a V-shaped protuberance which aligns with the V-shaped cut on the bolt by which exact alignment of the hammer with the bolt is assured and toward which the straight part of the cylinder presents a catch, whose function will be to prevent the cylinder from turning, being comprised of a small round-headed pin, connected transversely, and where at the interior of the cylinder is located a screw which unites with an alignment thread located in the center of the bolt in such a way that the screw keeps the two parts in a fixed position, in addition to a spring located in the interior of the cylinder where the interior walls of the end are fixed in such a way that the screw keeps the two parts in a fixed position and at the same time permits both pieces to run to one side;    under the hammer assembly, a trigger, whose function is to cause the execution of the impact of the cartridge, being connected to a plate, it is the piece below in the form of a canal with an elongated, slightly curved portion where the finger is rested to shoot the weapon and is mounted on the trigger support, comprised of a rectangular plate to which is attached the end of the trigger;    extending past the trigger, a protuberance which fits into the end of the trigger with which the cut of the trigger is formed and where said protuberance halts the advance of the hammer when the rifle is loaded and at the same time leaves the hammer free at the time of firing; and    a trigger support having at its other end a bore for the passing and fixing of the trigger support by way of a screw and where there is also a spring which stays compressed as much because of said screw as because of the trigger support upon its fastening in the mechanism chamber in such a way that, upon pulling the trigger, the trigger support, with the screw and the spring, move about a fixed point that corresponds to the point at which the screw assembly and the spring join, characterized by a trigger safety which functions so as to prevent accidental firing of the weapon and is fit to the combination of a rectangular plate in whose base there is a mechanism release window corresponding to the track of the trigger having in addition some bores in its corners in eyelet form that serve as guides for the course and movement of the trigger safety, from the base of the rectangular plate, the plate continuing with a section at ninety degrees and some curved pieces following the contour of the mechanism chamber, ending with a horizontal segment at each side;    said safety being attached in its curved sections via conventional screws and where on the right-hand side of the curved extension is a spring by which is determined the movement of safety release, signaled with a click, being comprised of a flat plate in whose center there is a vertical mark and that aligns with the alignment grooves located on the surface of the curved part of the safety; on the other side, the right-hand extension having on its face two threaded bores where two return stop screws are fixed, a first acting as a return stop where upon moving the bolt handle to load the rifle, the return stop screw moves and brings the safety toward the back in a secure position and at the same time brings the hammer to its final position and brings the protuberance into alignment with the terminal of the trigger in front of the hammer at which point it will be in position for loading, a second return stop acting as a point or peg to activate and release the safety manually, a third bore that serves as a window for observing the red alert point being marked on the butt.    
   
   
       2 . Safety for low (0.22) and similar caliber cartridge rifles, according to  claim 1 , further comprising: 
 a decorated cover to hide the screws, being comprised of not only the first return stop screw but also the second return stop screw, comprised of a safety support block with a rectangular cover and a screw, which upon placing said screw in the first threaded bore in the front, works as a return block and automatically activates the safety, upon changing the position to the second threaded bore in the back, the rifle being converted into the common repetition type, where the safety stays in the manual form.
