    [0002] Muzzleloader power cell with primer
    [0004] Cross reference to related requests
    [0006] This application claims the benefit of US Provisional Patent Application No. 62 / 794,669, filed on January 20, 2019, and US Non-Provisional Patent Application No. 016 / 686,130, filed on January 16, 2019. November 2019, the disclosure of which is incorporated herein by reference in its entirety to this invention.
    [0008] Background
    [0010] Muzzleloaders are a class of firearms in which the propellant charge and the bullet are loaded separately into the barrel immediately prior to firing. Unlike modern closure-loaded (breechloader) firearms, where the bullet, propellant charge, and primer are loaded as prepackaged cartridges, muzzleloaders are loaded by feeding a propellant charge through the muzzle before of ramming a bullet into the barrel with a ramrod until the bullet is seated against the propellant charge at the end of the barrel lock. A primer is inserted into the closure to communicate with the propellant. The primer is then struck by an in-line firing pin or external hammer to ignite the propellant charge and create propellant gases to propel the bullet.
    [0012] A variability in muzzleloader that is not present in cartridge-based firearms is the amount and type of propellant charge. Unlike cartridge firearms, in which a cartridge is preloaded with a bullet and a premeasured amount of propellant is loaded into the firearm to fire, the bullet and propellant charge are combined within the firearm to shoot. Consequently, the muzzleloader can select the optimal combination of bullet, propellant type, and quantity for each shot, which is particularly advantageous given the long reloading time of muzzleloaders. While the variability of the combination of bullet and propellant charge allows for optimized firing, varying the bullet and, in particular, the propellant and the amount of propellant can significantly change the proper seating depth of the bullet. With loose or powdered propellant, such as black powder, the amount of propellant often varies between 80 and 120 volumetric grains. Similarly, propellants are often formed into cylindrical granules that are stacked end to end within the barrel to form propellant charges. The granules are typically each about 1 cm in length and are loaded in groups of 1 to 3 granules, causing an even greater variation in seat depth. Of course, variability in gunpowder, bullet, and seat depth causes variability in performance, including accuracy.
    [0014] Another safety concern unique to muzzleloaders is too large or too small a propellant charge. Unlike cartridge firearms, where the amount of propellant loaded for each shot is limited by the internal volume of the cartridge, in theory the amount of propellant loaded for each shot in muzzleloaders is only limited by the length of the barrel. While measurements are often used to provide a constant amount of propellant for each propellant charge, measurements can be difficult to use in the field or in low ambient light when hunting often occurs. Similarly, the propellant can be formed into granules of predetermined size that can be charged one at a time until the proper amount of propellant is charged. As with measuring the amount of powder, errors can occur when loading the appropriate amount of granules. The embodiments of the description address the above problems.
    [0016] Description Summary
    [0018] All conventional firearms are designed, manufactured, and stored to fire a single size of ammunition. Ammunition of the wrong size must not seat properly in the chamber and otherwise must not be allowed to fire. Bolt action firearms, such as single shot shotguns and double barrel shotguns, conventionally have a flat face of the bolt block with a center hole of the firing pin with a flat face of the bolt block. The owner of the present application has developed muzzleloader systems with closure-loaded, sealed propellant cartridges and have been described as having a flat face of the closure block. See, for example, U.S. Patent No. 010,030,956, incorporated herein as reference except for express definitions and patent claims contained therein. The applicant has developed unconventional interface systems between the face of the closure block and the cartridges that provide a high level of assurance that only intended propellant canisters can be fired in muzzleloaders.
    [0020] In some embodiments of the disclosure, a muzzleloader has a muzzleloader that has a barrel with a rearward-opening breech, a constriction portion in front of the breech, and a reduced-size barrel bore at the front. of the constriction part. A projectile is loaded through the muzzle and a hermetically sealed, prepackaged propellant charge having a polymer container filled with propellant is loaded through the closure into the breech of the closure. The polymer container includes a flange at a rear end and a centrally positioned primer receptacle at the rear end. In some embodiments, the cooperative features between the rear face of the polymer container and the muzzleloader's closure block provide means to limit engagement of the firing pin with only a polymer container specifically configured with the primer.
    [0022] In some embodiments, the muzzleloader has a chamber for receiving the polymer propellant canister and a face of the closure block that exhibits a more forward-extending structure within the rearward axial projection of the chamber, a receiving surface. of the primer on the face of the closure block that is positioned rearward of the forward-extending frame, and a striker that does not extend forward beyond the forward-extending frame. In some embodiments, the most forward-extending structure is a projection such as one or more pins, or such as an annular projection, that engage a corresponding recess in the rear face of the propellant canister. In some embodiments, the most advanced structure is a flat face of the closure block that faces the face of the closure around the breech, and the primer-receiving surface of the face of the closure block is positioned at the bottom of a cylindrical recess surrounding a hole in the firing pin.
    [0024] In some embodiments, a muzzleloader polymer propellant container has a recess of the primer with a depth that is less than the total height of the primer such that the primer, when inserted into the primer receptacle, extends rearwardly beyond a rearward-facing surface of the propellant containment vessel. The face of the muzzleloader's closure block may define a recess dimensioned to receive the primer. The firing pin of the rifle can be configured not to extend beyond a flat face of the closure block surface surrounding the recess. In some embodiments, the back face of the propellant container has an annular polymeric projection defining the portion of the primer receptacle therein to receive the primer with a flange, the flange seating on the rear face of the annular polymeric projection. The face of the closure block may define a recess configured to receive a polymer projection and a primer installed therein. In some embodiments, the components are configured such that the inner face of the recess in the face of the closure block is compression-coupled with the primer flange and the polymer projection.
    [0026] In some embodiments, a rimfire primer is inserted into a primer socket and the firing pin hole and firing pin drive region is offset from the center axis of the breech. The rimfire primer may extend from the rear face of the polymer container or it may seat in a centrally positioned annular projection. In some embodiments, one or more means to limit engagement of the firing pin may be combined with only one polymer container specifically configured with the primer.
    [0028] An exemplary muzzleloader system includes a propellant containment vessel for use with a primer, a projectile, and a muzzleloader. In some embodiments, the system includes a propellant containment vessel separate from the primer and projectile so that the propellant containment vessel is not in contact with the projectile and the primer does not contact the propellant containment vessel until an assembly stage has been completed. In some embodiments, the propellant containment vessel is sized to be received in the breech of the closure and has a head portion with a flange and a primer receptacle. A body part may taper towards a forward end with the forward end shaped to engage a constriction portion in the muzzleloader. The propellant canister may include means to prevent loading of the canister into a firearm other than a firearm. intended muzzle-loading rifle. The muzzleloader may include means to prevent the firing of any ammunition, except for a propellant canister specifically configured and configured with a primer inserted therein.
    [0030] In some embodiments, the system is sized and adapted for use with a muzzleloader that has a firing pin and a pair of locating pins. The striker can slide between a more forward position and a more rearward position. In some embodiments, the striker extends forwardly beyond a forward-facing surface of a closure block by a first distance when the striker is in the most forward position. In some embodiments, each locating pin extends forwardly beyond the forward-facing surface of a latch block by a second distance. The second distance can be greater than the first distance so that the striker does not extend through a plane defined by the forward surfaces of the locating pins when the striker is in the forward most position.
    [0032] A feature and benefit of various embodiments of the disclosure is a muzzleloader power cell capsule that includes a rear portion containing a propellant charge and a front portion covering a front opening in the rear portion. In some embodiments, the nose is ejected from the muzzleloader when the propellant is turned on.
    [0034] A feature and benefit of various embodiments of the disclosure is a muzzleloader that includes a power cell containing a propellant charge for use with a bullet that is not attached to the power cell. In some embodiments, the lack of bond between the power cell and the bullet can provide greater accuracy when the bullet is fired. In some embodiments, the propellant-charged power cell is loaded through the rear end of the barrel closure and the bullet is loaded through the forward end of the muzzle.
    [0036] A feature and advantage of various embodiments of the disclosure is that loading or unloading of the propellant charge by the closure allows for safe separation of the propellant charge from the loaded bullet within the barrel. When you want to download the loader from muzzleloader, the propellant containment vessel is removed, discharged from the closure and then the bullet is extracted or safely pushed down the barrel and removed from the muzzleloader without risk of inadvertent or delayed ignition of the propellant charge and subsequent firing of the projectile.
    [0038] A feature and benefit of various embodiments of the disclosure is a muzzleloader system power cell that includes a transparent or translucent body part containing a propellant charge and a cover part hermetically sealed to the body part. In some embodiments, the transparent or translucent body portion allows visual inspection of the cargo without breaking the hermetic seal. In some embodiments, the cap portions are color-coded in a manner representative of the types and / or amounts of propellant. The lid can be at the front or rear end of the container part.
    [0040] A feature and benefit of various embodiments of the disclosure is a muzzleloader system that includes a power cell containing a propellant charge sized and adapted to propel a bullet weighing more than 200 grains to provide rapid and humane death during firing. hunting. In some embodiments, the muzzleloader includes a power cell that contains a propellant charge sized and adapted to propel a bullet that weighs more than 250 grains. In some embodiments, the muzzleloader includes a power cell that contains a propellant charge sized and adapted to propel a bullet that weighs more than 300 grains. Some embodiments in this invention are specifically directed at 45 caliber to 50 caliber muzzle-loaded projectiles.
    [0042] A feature and benefit of various embodiments of the disclosure is a muzzleloader that includes a power cell containing a propellant charge for use with a primer and bullet, the bullet being sized so that the muzzleloader is suitable for its use. use in big game such as elk, goose and bear.

    [0109] Detailed description of the drawings
    [0111] With reference to FIGS. 1-3, a muzzle-loading system 20 includes a muzzle-loading rifle 22, a muzzle-loaded projectile 25, a closure-loaded muzzle-loading power cell 32 having a primer receptacle 34 and a primer 38 insertable into the receptacle. of primer 34 of muzzleloader power cell 32. Muzzleloader power cell 32 includes a propellant containment vessel 40 containing a quantity of propellant. In some embodiments, muzzleloader power cell 32 is separated from primer 38 and projectile 25 until the system is ready to fire.
    [0113] In some embodiments, the muzzleloader 20 has a closure brake 42 that opens as shown in FIG. 2 that reveals a closure 43 face of the closure 44 end of a barrel 46. A closure block 48 has a face of the closure block 50 facing the face of the closure 43. A rearwardly open breech 60 of closure, a constriction portion 54, is positioned in front of the breech of closure 60, and a bore of the barrel 31 in front of the constriction portion 54 extending to a muzzle 56. Muzzleloader power cell 32 is dimensioned to be conformally received in breech of closure 60. Muzzleloader 22 includes a trigger mechanism 64 to actuate a firing pin70.
    [0115] In this invention, "forward" and its derivatives (eg forward, later) is designated by arrow 71 which refers to a direction that is parallel to the z axis of the r-0-z axis. of FIG. 2 and parallel to a direction of travel of the projectile 25 after discharge. "Back" and its derivatives (eg, backward, further back) is a direction opposite to the forward direction 71, designated by arrow 73.
    [0117] With specific reference to FIG. 3, in some embodiments, the closure block 48 has two relevant surfaces that are within a rearward axial projection 72 of the breech of the closure 60, one is a forward-most surface 74, and the other is a facing surface of the closure. primer 76 that is forward facing and extends around the firing pin opening and the firing path of travel. In some embodiments, the travel of the firing pin is restricted to have a forward stopping position so that forward travel is precluded beyond a plane 77 perpendicular to the axis of the barrel A1 positioned on the forward most surface 74 of the closure block. . In some embodiments, when the muzzleloader is loaded and ready to fire, the forward-most surface of the closure block is forward of the rearmost surface of the propellant canister with primer 38. Positioning as such limits the firing pin to hitting only. propellant vessels specially configured in accordance with primers 38.
    [0119] With reference to FIG. 4 shows suitable example dimensions for muzzleloader power cell 32 in accordance with one embodiment of the disclosure. Dimensions are presented by way of example and are not limiting. In some embodiments, the dimensions may vary within 5% of the specified values.
    [0121] With reference to FIGS. 5A and 5B, a muzzleloader power cell 32a is depicted according to one embodiment of the disclosure. Muzzleloader power cell 32a includes propellant containment vessel 40a. In this invention, muzzleloader power cells and propellant containment vessels are collectively and genetically referred to as "muzzleloader power cell (s) 32" and "propellant containment vessel (s) 40", and specific or individually by reference characters 32 and 40, respectively, followed by a letter suffix (eg, "muzzleloader power cell 32a" and "propellant containment vessel 40a"). The propellant containment vessel 40a includes a front body portion 82 that includes a tubular wall portion 83, the front body portion 82 defining a cavity 84 that contains an amount o propellant charge 85. The front body portion 82 extends rearwardly from a front end portion 106, concentric about the axis of the body 87 and defines a rear mouth 87. A rear cup 86 is disposed in the rear mouth 87 which closes and seals the propellant 85 within the cavity 84. Certain aspects of the configuration of FIGS.
    [0122] 5A and 5B are explained in more detail in the international patent application publication WO 2019/144161, owned by the assignee of the current application, the content of which is incorporated in this invention by reference in its entirety, with the exception of the patent claims and the express definitions contained therein.
    [0124] Referring to FIGS. 6 and 7, a muzzleloader power cell 32b is depicted according to one embodiment of the disclosure. Muzzleloader power cell 32b includes some of the same components and attributes as muzzleloader power cell 32a, which are identified by reference characters of the same number. Muzzleloader power cell 32b includes a propellant containment vessel 40a having a rear body portion 90 that defines cavity 84 and extends forward and defines a front mouth 91. Front mouth 91 is configured to receive a lid front 92 to seal the thruster 85 inside.
    [0126] With reference to FIGS. 8 to 14 and again to FIGS. 4-7, propellant containment vessels 80 include a rear or upper end portion 94 with a flange 96 defining a primer receptacle 98 defining a primer recess 99, and a rear flange face 102. A membrane 97 isolates cavity 84 and primer recess 99 so that, prior to discharge, there is no fluid communication between cavity 84 and primer recess 99. Front end portion 106 of muzzleloader power cell 32 is shaped to fit the constriction portion 54 of the muzzleloader 22.
    [0128] With reference to FIGS. 9 and 10 and again to FIGS. 5A and 5B, muzzleloader power cells 32a and 32b are shown according to the embodiments of the description. Muzzleloader power cells 32a and 32b include propellant containment vessels 40a and 40b, each defining an annular recess 120 for receiving cooperating structures 122 (FIGS.
    [0129] 21 and 22) on the face of closure block 50. Cooperating structures 122 may include, for example, pins 124 (FIG. 21) or an annular projection 126 (FIG. 22). In such Arrangements, an end surface 130 of pins 124 and a rear end 136 of annular projection 126 constitute the forwardmost surfaces 74 of the face of closure block 50 as described above. Striker 70 is configured not to extend forward of forwardmost surfaces 74 when actuated.
    [0131] With reference to FIGS. 11 and 12 In some embodiments, recess 99 in primer socket 98 of propellant containment vessel 40 has a depth D that is less than an overall height H of primer 38 such that primer 38, such that when inserted into Primer receptacle 98, primer 38 including primer flange 146, extends rearwardly beyond rearward facing flange face 102 of propellant containment vessel 32. In some embodiments, the muzzleloader includes means that prevent the firing of a rifle cartridge from the muzzleloader 20.
    [0133] With reference to FIGS. 13 and 14, flange 96 includes annular projection 126 with primer recess 99 defined therein. The annular projection extends an axial length L1 beyond the rear flange face 102 of flange 96 in the rearward direction 73. After installation of primer 38, annular projection 126 and primer flange 146 of primer 36 are stack to project rearward, defining an axial length L2 relative to rear flange face 102 of flange 96.
    [0135] With reference to FIGS. 15-17, a muzzleloader power cell 32f is depicted including a powder disc secured with roll crimps in accordance with one embodiment of the disclosure. Muzzleloader power cell 32f includes several of the same components and attributes as muzzleloader power cell 32e, some of which are indicated by reference characters of the same number. The muzzleloader power cell 32f includes a propellant containment vessel 40f, primer 38, propellant 85, and a powder disk 202 attached to the front mouth 91. The propellant containment vessel 40f may be of a transparent or translucent material ( depicted), as discussed above. The powder disk 202 is captured at the forward end 106 of the propellant containment vessel 40f between a flange portion 204 and a roll crimp 206 of the propellant containment vessel 40f to close and seal the propellant 85 within the cavity 84 .
    [0136] Muzzleloader power cell 32f defines an overall axial length 208, extending from a rear end 212 of annular projection 146 to a forward end 214 of roll crimp 206 of propellant containment vessel 40f. The propellant containment vessel 40f defines an axial body length 216 extending from a front face 218 of flange 96 to the front end 214 of roll crimp 206, and also defines an axial insertion length 220 of the breech chamber. closure extending from a rear face of flange 96 to forward end 214 of roll crimp 206. In operation, muzzleloader power cell 32f is inserted into the breech of closure 60 so that roll crimp 206 is Register against constriction portion 54 of muzzleloader 22.
    [0138] With reference to FIG. 18, the propellant containment vessel 40f is shown prior to assembly of the muzzleloader power cell 32f according to one embodiment of the disclosure. The propellant containment vessel 40f is a unitary polymeric structure 232 that includes the flange 96, the primer receptacle 98, and the membrane 97 in the rear end portion 94. In the forward end portion 106, the propellant containment vessel 40f defines the rim portion 204 that is behind the front mouth 91, the rim portion 204 projecting radially inward (i.e., toward the axis of the body 87) from an interior surface 236 of the tubular wall portion 83 of the 40f propellant containment vessel. The rim portion 204 defines a seating face 238 that faces forward toward the front mouth 91. In some embodiments, the rim portion 204 is a continuous annular rim. In some embodiments, rim portion 204 is a shoulder 242 (shown) that lies in a transition zone between a proximal thick wall portion 244 and a distal thin wall portion 246 of tubular wall portion 83. In some embodiments In embodiments, an outer surface 248 of the tubular wall portion 83 of the propellant containment vessel 40f (as well as for the propellant containment vessels 40 in general) tapers toward the axis of the body 87 in the direction of advance 71.
    [0140] The unitary polymeric structure 232 of the propellant containment vessel 40f (as well as for the propellant containment vessels 40 in general) can be manufactured by techniques known to those skilled in the art, such as injection molding, machining, or a combination thereof. For example, the unitary polymeric structure 232 can be initially molded by injection molding technique that is finished by machining techniques to provide tighter tolerances of critical surfaces and lengths (e.g., seat face 238 of flange portion 204, rear flange face 102, axial length L1 to the rear end 136 of the annular projection 126 and / or a thickness of the distal thin wall portion 246). The powder disk 202 can be made, for example, from a polymer or cardboard.
    [0142] Functionally, annular projection 126 provides the same safety features as muzzleloader 32e, previously described in connection with FIGS. 13 and 14. Membrane 97 prevents propellant 85 from leaking out of cavity 84 into primer receptacle 98 during shipping, storage, and handling. Flange portion 204 provides a reliable seating position along the axis of body 87 for powder disc 202, and cooperates with roll crimp 206 to secure powder disc 202 and seal cavity 84. The distal thin wall 246 can allow easier and more reliable formation of the crimp roll 206, while the proximal thick wall portion 244 provides the necessary structural integrity of the propellant containment vessel 40f to prevent breakage of the power cell of 32f muzzleloader during unloading. The taper of the outer surface 248 may conform to a complementary shaping inner wall of the breech of the closure 60 for better support of the muzzleloader power cells 32 (and the muzzleloader power cells 32 in general) during unloading.
    [0144] With reference to FIGS. 19A to 19C, a method of manufacturing the muzzleloader power cell 32f according to one embodiment of the disclosure is depicted. A representation of the fully assembled power cell 32f is shown in FIG. 20. The unitary polymeric structure 232 of propellant containment vessel 40f may be subjected to the fabrication and finishing procedures described above accompanying FIG. 18. The propellant 85 is disposed in the rear body portion 90 of the unitary polymeric structure 232 (FIG. 19A). The powder disk 202 is inserted into the front mouth 91 so that a rear face 252 of the powder disk 202 seats in the rim portion 204 of the propellant containment vessel 40f (FIG. 19B).
