Definitions
- the invention relates to a muzzle-loading firearm having a break-action design and, more specifically, to a muzzle-loading firearm having a break-action design that includes a barrel and a slidable hood locking system that locks the barrel in a closed position.
- Muzzle-loading firearms are configured so that powder and bullets must be loaded at the muzzle or forward end of the barrel.
- a typical muzzle-loading firearm has a barrel with a breech plug attached to occupy an enlarged rear bore portion, breech plug chamber, of the barrel at the breech or rear end thereof.
- the breech plug is permanently attached.
- the breech plug is removable to facilitate pass-through cleaning of the bore.
- Break-action muzzle-loading firearms facilitate access to the breech plug by pivotally mounting the barrel to the receiver or the forend of the muzzle-loading firearm, which enables the breech end of the barrel to be separated, via a pivoting action, from the receiver.
- a device can be utilized to block or obstruct the rear of the receiver.
- positioning a device in the area of the rear of the receiver can interfere with the accessibility and removal of the breech plug.
- positioning a device in the breech end of the barrel can interfere with the barrel-locking mechanism of the break open muzzle-loading firearm. For this reason, the rear of the receiver is often left open or unobstructed to allow access to and replacement of the breech plug.

- the ramrod 18 is fitted to be received between the forend 16 and the barrel 20 .
- the barrel 20 includes a bore that defines a bore axis 22 and has a rear (i.e., breech) end 24 .
- the muzzle-loading firearm 10 also has a trigger 26 mounted to a bottom surface of the receiver 14 and a hammer 28 mounted to the rear of the receiver 14 .
- the trigger 26 and the hammer 28 are in mechanical communication with each other, such that the hammer 28 is actuated in response to actuation of the trigger 26 .
- FIGS. 2-3 cross sections of the muzzle-loading firearm 10 are shown to illustrate the break-action design.
- the barrel 20 is shown in the closed (i.e., firing) position.
- the rear end 24 of the barrel 20 lies flush against an upper portion 30 of the receiver 14 .
- a bushing 32 is mounted to a front facing surface of the upper portion 30 of the receiver 14 .
- the bushing 32 defines a hole 34 in the center thereof.
- a striking pin 36 is located within the hole 34 of the bushing 32 to communicate the action of the hammer 28 to an ignition cap (not shown for clarity) in a breech plug 38 disposed in the rear end 24 of the barrel 20 .
- the barrel 20 is retained in the closed position by a locking bar 40 that slides under a ledge 42 formed in the front facing surface of the upper portion 30 of the receiver 14 , substantially below where the bushing 32 is mounted.
- the locking bar 40 is spring biased into a closed position, as shown in FIG. 2 , and is actuated axially forward to disengage from the ledge 42 in response to an actuation of a trigger guard 44 for opening the break action muzzle-loading firearm 10 .
- the muzzle-loading firearm 10 is shown in the open position.
- the rear end 24 of the barrel 20 can be easily accessed, for instance, to service the barrel 20 or replace the breech plug 38 .
- the barrel 20 is swung into the open position by actuating the trigger guard 44 , which releases the locking bar 40 from engagement with the ledge 42 and allows the barrel 20 to swing open about a lug 46 .
- the lug 46 is disposed in a forward portion of the receiver 14 and connects to the forend 16 . As is known in the art, the lug 46 is fixedly secured. For example, the lug 46 is welded in place. The lug 46 is fixedly disposed on the muzzle-loading firearm 10 in order to provide a secure connection that can endure the forces experienced by this pivot point during operation of the muzzle-loading firearm 10 .
- the breech plug 38 substantially seals the rear end 24 of the barrel 20 and that the connection of the barrel 20 to the bushing 32 further seals the rear end 24 of the barrel 20 . Additionally, the outer surface of the barrel 20 defines a gap 48 at a lower position thereof. The gap 48 offers a low resistance path for the exhaust gas to flow from the rear end 24 of the barrel 20 downward into the receiver 14 .
- the muzzle-loading firearm 50 which has a break-action design, includes a stock 52 that is connected to a receiver 54 by a bolt 56 that extends into corresponding recesses in the stock 52 and the receiver 54 .
- the receiver 54 is fitted to mount to a rectangular recess 58 formed in the stock 52 so that, when assembled, the receiver 54 is covered to the rear, the bottom, and the sides by the stock 52 .
- a fixed trigger guard 60 is disposed along a lower surface of the stock 52 , generally below the receiver 54 .
- the stock 52 extends forward of the receiver 54 and has a convex surface 62 at a forward end thereof.
- the convex surface 62 slidably connects to a matching concave surface 64 of a forend 66 , which is pivotally mounted to the receiver 54 about a screw or screws 68 .
- the screw 68 is used in place of the lug 46 as known in the art. This substitution is enabled because the forces experienced at this pivot point of the muzzle-loading firearm 50 of the present invention have been reduced relative to those experienced in the muzzle-loading firearm 10 of the prior art. The reduction in forces experienced at this pivot point allows a removable (i.e., screw) connection instead of the fixed connection of the prior art.
- the forend 66 receives a barrel 70 having a rear end 72 with a breech plug 74 inserted in a breech plug chamber thereof.
- the outer surface of the barrel 70 is tapered at the rear end 72 , which defines a circumferential recess 76 in the barrel 70 adjacent to the rear end 72 .
- the removable screw configuration facilitates the manufacture and repair of the muzzle-loading firearm 50 .
- the barrel 70 since the barrel 70 is releasably connected to the receiver 54 , the barrel 70 may be removed to perform precision machining process steps. As one example, the barrel 70 may be removed from the receiver 54 for processing and/or repair.
- the muzzle-loading firearm 50 may be assembled in a different order and, in particular, the sub-components of the muzzle-loading firearm 50 may be fully processed and then assembled.
- the barrel can be drilled after the barrel has been permanently welded to the receiver by the lug. This known approach is cumbersome, unwieldy and renders the manipulation and processing of the barrel more time consuming and prone to error.
- a hood 78 is slidably mounted to the receiver 54 , such that the hood 78 is configured to slide forward and rearward on the receiver 54 , parallel to the firing axis of the muzzle-loading firearm 50 .
- the hood 78 defines a tapered opening 80 at the front-end thereof.
- the tapered opening 80 is fitted to receive the circumferential recess 76 of the barrel 70 .
- the hood 78 slidably engages the barrel 70 and locks the barrel 70 in the closed position (i.e., in battery) as shown in FIG. 4 .
- the hood 78 which circumscribes the barrel 70 and, in particular, secures the rear end 72 of the barrel 70 from the pivot point (i.e., screw 68 ), more robustly secures the barrel 70 in the closed position relative to known locking bars 40 (see FIGS. 2-3 ).
- the hood 78 encases an upper portion 82 of the receiver 54 .
- a bushing 84 is mounted to a front-facing surface of the upper portion 82 of the receiver 54 .
- the breech plug 74 forms a seal at the rear end 72 of the barrel 70 and the connection of the rear end 72 of the barrel 70 to the upper portion 82 of the receiver 54 and the bushing 84 forms a further seal. Additionally, the hood 78 of the present invention forms yet another seal therearound, further blocking exhaust gas from flowing out of the rear end 72 of the barrel 70 .
- a yoke 90 extends from the rear of the hood 78 .
- the yoke 90 receives a pin 92 that is connected to one end of a spring-biased shaft 94 .
- the other, remote end of the spring-biased shaft 94 is received in a recess 96 formed in the stock 52 .
- the spring-biased shaft 94 spring biases the hood 78 forward and into engagement with the barrel 70 when in the closed position.
- the barrel 70 is released from the closed position.
- the hood 78 slides rearward on the receiver 54 and out of engagement with the barrel 70 , thereby allowing the barrel 70 and the forend 66 to swing about the screw 68 into the open position shown in FIG. 5 .
- the rear end 72 of the barrel 70 is readily accessible, for instance, so that the barrel 70 can be serviced and the breech plug 74 can be removed.
- the hood 78 lies substantially flush with the contours of the muzzle-loading firearm 50 .
- a top surface 98 of the hood 78 aligns with a top surface 100 of the barrel 70 .
- a rear surface 102 of the hood 78 aligns with a top surface 104 of the stock 52 .
- the concave surface 64 of the forend 66 abuts the convex surface 62 of the stock 52 . It should be appreciated from the portion of the muzzle-loading firearm 50 shown in FIG. 6 that the receiver (not shown in FIG. 6 ) is substantially encased or housed within the stock 52 .
- a trigger 106 is mounted to a lower surface of the muzzle-loading firearm 50 , below where the receiver 54 is housed in the stock 52 , and extends from an opening formed in the stock 52 .
- a hammer 108 is mounted to the rear of the receiver 54 and extends from an opening formed in the rear surface 102 of the hood 78 . It should be appreciated that the hammer 108 is in mechanical communication with the trigger 106 so that the hammer 108 is actuated in response to the actuation of the trigger 106 .

Abstract
A muzzle-loading firearm having a break-action design includes a stock, a receiver mounted to the stock, a forend pivotally mounted to the receiver and a barrel mounted to the forend. A hood is slidably attached to a top surface of the receiver in the area of a rear (i.e., breech) end of the barrel. The hood reciprocally engages and locks the barrel in a closed (i.e., firing) position. The hood also shields the area surrounding the breech end of the barrel from exhaust gas that flows therefrom.
Description
- This application claims the benefit of U.S. Provisional Application No. 61/423,301, filed Dec. 15, 2010, entitled “SLIDABLE HOOD LOCKING SYSTEM”, the aforementioned application being hereby incorporated by reference in its entirety.
- The invention relates to a muzzle-loading firearm having a break-action design and, more specifically, to a muzzle-loading firearm having a break-action design that includes a barrel and a slidable hood locking system that locks the barrel in a closed position.
- Muzzle-loading firearms are configured so that powder and bullets must be loaded at the muzzle or forward end of the barrel. A typical muzzle-loading firearm has a barrel with a breech plug attached to occupy an enlarged rear bore portion, breech plug chamber, of the barrel at the breech or rear end thereof. In some muzzle-loading firearms, the breech plug is permanently attached. In others, the breech plug is removable to facilitate pass-through cleaning of the bore.
- Break-action muzzle-loading firearms facilitate access to the breech plug by pivotally mounting the barrel to the receiver or the forend of the muzzle-loading firearm, which enables the breech end of the barrel to be separated, via a pivoting action, from the receiver.
- With removable breech plugs, and, in particular, with removable breech plugs of break-action muzzle-loading firearms, there is a need to maintain a proper seal of the breech end of the barrel. The presence of a leak in the seal can result in smoke, or vapor projecting from the receiver, which may not be desirable, especially if a riflescope is mounted to the gun.
- In order to reduce the incidence of these projections from the receiver, the quality of the seal can be improved. Alternatively, a device can be utilized to block or obstruct the rear of the receiver. However, positioning a device in the area of the rear of the receiver can interfere with the accessibility and removal of the breech plug. In addition, positioning a device in the breech end of the barrel can interfere with the barrel-locking mechanism of the break open muzzle-loading firearm. For this reason, the rear of the receiver is often left open or unobstructed to allow access to and replacement of the breech plug.
- An object of the present invention is, therefore, to provide a hood for a muzzle-loading firearm having a break-action design, which, among other desirable attributes, significantly reduces or overcomes the above-mentioned deficiencies of prior muzzle-loading firearms.
- Accordingly, the present invention provides a muzzle-loading firearm having a break-action design including a barrel that is secured in a closed (i.e., firing) position by a hood.
- It is an object of the present invention to provide a hood that receives and secures a breech-end of the barrel of the muzzle-loading firearm in the closed position.
- It is an object of the present invention to provide a hood that protects a device that is mounted to the muzzle-loading firearm, such as a sight, from exhaust gas that might flow from a breech end of a barrel of the muzzle-loading firearm.
- In an aspect of the present invention, a muzzle-loading firearm is provided that includes a barrel and a hood that locks the barrel in the closed position, a breech end of the barrel defining a circumferential recess that is fitted to a corresponding tapered opening of the hood.
- In an aspect of the present invention, a muzzle-loading firearm is provided that has a break-action design, the firearm including a stock with a convex front surface and a forend with a concave rear surface that is fitted to slidably contact the convex front surface of the stock when the muzzle-loading firearm is actuated between the open position and the closed position.
- In an aspect of the present invention, a muzzle-loading firearm is provided that has a receiver and a stock that encases or houses the receiver therein.
- In an aspect of the present invention, a muzzle-loading firearm is provided that has a receiver that defines a recess, which defines a locking wall, a block that is pivotally mounted in the recess, and a forend that is mounted to the block, the locking wall blocking the rotation of the block, thereby limiting the rotation of the forend relative to the receiver. In another aspect of the present invention, the limiting wall defines an opening and the muzzle-loading firearm also has an adjustable cap screw with an upward end that is inserted in the opening, the rotation of the cap screw causing the upward end to actuate into the pivot path of the block, thereby further limiting the rotation of the forend relative to the receiver.
- In an aspect of the present invention, a hood is provided that is slidably mounted to a receiver of a muzzle-loading firearm.
- In an aspect of the present invention, a hood is provided that is secured to a receiver by a spring-biased shaft. In another aspect of the present invention, the hood includes a yoke having openings fitted to receive a pin of the spring-biased shaft. In another aspect of the present invention, the spring-biased shaft biases the hood in a forward (i.e., closed) position.
- In an aspect of the present invention, a hood is provided that includes forward ridges and rearward ridges that are fitted to engage forward and rearward protrusions, respectively, that extend laterally from a receiver.
- In an aspect of the present invention, the hood has a bottom surface that is fitted to a top surface of the receiver, the bottom surface of the hood and the top surface of the receiver having mating tiered structures.
- In an aspect of the present invention, a hood is provided that defines a rearward slot, which is fitted to receive a hammer of a muzzle-loading firearm.

- Referring to
FIG. 1 , a muzzle-loading firearm 10 having a break-action design, as known in the art, is shown. The muzzle-loading firearm 10 includes astock 12 that is connected to areceiver 14. Thereceiver 14 is pivotally connected to aforend 16 via a lug 46 (shown inFIGS. 2-3 ), which has aramrod 18 and abarrel 20 mounted thereto. Theramrod 18 is fitted to be received between theforend 16 and thebarrel 20. Thebarrel 20 includes a bore that defines abore axis 22 and has a rear (i.e., breech)end 24. - The muzzle-
loading firearm 10 also has atrigger 26 mounted to a bottom surface of thereceiver 14 and ahammer 28 mounted to the rear of thereceiver 14. Thetrigger 26 and thehammer 28 are in mechanical communication with each other, such that thehammer 28 is actuated in response to actuation of thetrigger 26. - A similar muzzle-loading firearm is disclosed in U.S. Pat. No. 6,604,311 to Laney et al., the disclosure of which is incorporated herein by reference.
- Referring to
FIGS. 2-3 , cross sections of the muzzle-loading firearm 10 are shown to illustrate the break-action design. Referring now toFIG. 2 , thebarrel 20 is shown in the closed (i.e., firing) position. Therear end 24 of thebarrel 20 lies flush against anupper portion 30 of thereceiver 14. Abushing 32 is mounted to a front facing surface of theupper portion 30 of thereceiver 14. Thebushing 32 defines ahole 34 in the center thereof. Astriking pin 36 is located within thehole 34 of thebushing 32 to communicate the action of thehammer 28 to an ignition cap (not shown for clarity) in abreech plug 38 disposed in therear end 24 of thebarrel 20. - The
barrel 20 is retained in the closed position by a lockingbar 40 that slides under aledge 42 formed in the front facing surface of theupper portion 30 of thereceiver 14, substantially below where thebushing 32 is mounted. The lockingbar 40 is spring biased into a closed position, as shown inFIG. 2 , and is actuated axially forward to disengage from theledge 42 in response to an actuation of atrigger guard 44 for opening the break action muzzle-loading firearm 10. - Referring now to
FIG. 3 , the muzzle-loading firearm 10 is shown in the open position. In the open position, therear end 24 of thebarrel 20 can be easily accessed, for instance, to service thebarrel 20 or replace thebreech plug 38. Thebarrel 20 is swung into the open position by actuating thetrigger guard 44, which releases the lockingbar 40 from engagement with theledge 42 and allows thebarrel 20 to swing open about alug 46. - The
lug 46 is disposed in a forward portion of thereceiver 14 and connects to theforend 16. As is known in the art, thelug 46 is fixedly secured. For example, thelug 46 is welded in place. Thelug 46 is fixedly disposed on the muzzle-loading firearm 10 in order to provide a secure connection that can endure the forces experienced by this pivot point during operation of the muzzle-loading firearm 10. - It should be appreciated that the
breech plug 38 substantially seals therear end 24 of thebarrel 20 and that the connection of thebarrel 20 to thebushing 32 further seals therear end 24 of thebarrel 20. Additionally, the outer surface of thebarrel 20 defines agap 48 at a lower position thereof. Thegap 48 offers a low resistance path for the exhaust gas to flow from therear end 24 of thebarrel 20 downward into thereceiver 14. - Referring to
FIGS. 4-5 , cross sections of a portion of a muzzle-loading firearm 50 in accordance with the present invention are shown. The muzzle-loading firearm 50, which has a break-action design, includes astock 52 that is connected to areceiver 54 by abolt 56 that extends into corresponding recesses in thestock 52 and thereceiver 54. Thereceiver 54 is fitted to mount to arectangular recess 58 formed in thestock 52 so that, when assembled, thereceiver 54 is covered to the rear, the bottom, and the sides by thestock 52. - A fixed
trigger guard 60 is disposed along a lower surface of thestock 52, generally below thereceiver 54. - The
stock 52 extends forward of thereceiver 54 and has aconvex surface 62 at a forward end thereof. Theconvex surface 62 slidably connects to a matchingconcave surface 64 of aforend 66, which is pivotally mounted to thereceiver 54 about a screw or screws 68. Due to various design modifications made to the muzzle-loading firearm 50 of the present invention, as is discussed elsewhere in this application, thescrew 68 is used in place of thelug 46 as known in the art. This substitution is enabled because the forces experienced at this pivot point of the muzzle-loading firearm 50 of the present invention have been reduced relative to those experienced in the muzzle-loading firearm 10 of the prior art. The reduction in forces experienced at this pivot point allows a removable (i.e., screw) connection instead of the fixed connection of the prior art. - The
forend 66 receives abarrel 70 having arear end 72 with abreech plug 74 inserted in a breech plug chamber thereof. The outer surface of thebarrel 70 is tapered at therear end 72, which defines acircumferential recess 76 in thebarrel 70 adjacent to therear end 72. - The removable screw configuration facilitates the manufacture and repair of the muzzle-
loading firearm 50. For instance, since thebarrel 70 is releasably connected to thereceiver 54, thebarrel 70 may be removed to perform precision machining process steps. As one example, thebarrel 70 may be removed from thereceiver 54 for processing and/or repair. By being able to remove thebarrel 70 from thereceiver 54 the muzzle-loading firearm 50 may be assembled in a different order and, in particular, the sub-components of the muzzle-loading firearm 50 may be fully processed and then assembled. In contrast, in known muzzle-loading firearms, as shown inFIGS. 1-3 , the barrel can be drilled after the barrel has been permanently welded to the receiver by the lug. This known approach is cumbersome, unwieldy and renders the manipulation and processing of the barrel more time consuming and prone to error. - A
hood 78 is slidably mounted to thereceiver 54, such that thehood 78 is configured to slide forward and rearward on thereceiver 54, parallel to the firing axis of the muzzle-loading firearm 50. Thehood 78 defines a taperedopening 80 at the front-end thereof. The taperedopening 80 is fitted to receive thecircumferential recess 76 of thebarrel 70. Thehood 78 slidably engages thebarrel 70 and locks thebarrel 70 in the closed position (i.e., in battery) as shown inFIG. 4 . Thehood 78, which circumscribes thebarrel 70 and, in particular, secures therear end 72 of thebarrel 70 from the pivot point (i.e., screw 68), more robustly secures thebarrel 70 in the closed position relative to known locking bars 40 (seeFIGS. 2-3 ). - The
hood 78 encases anupper portion 82 of thereceiver 54. Abushing 84 is mounted to a front-facing surface of theupper portion 82 of thereceiver 54. - It should be appreciated that the
breech plug 74 forms a seal at therear end 72 of thebarrel 70 and the connection of therear end 72 of thebarrel 70 to theupper portion 82 of thereceiver 54 and thebushing 84 forms a further seal. Additionally, thehood 78 of the present invention forms yet another seal therearound, further blocking exhaust gas from flowing out of therear end 72 of thebarrel 70. - A
yoke 90 extends from the rear of thehood 78. Theyoke 90 receives apin 92 that is connected to one end of a spring-biasedshaft 94. The other, remote end of the spring-biasedshaft 94 is received in arecess 96 formed in thestock 52. The spring-biasedshaft 94 spring biases thehood 78 forward and into engagement with thebarrel 70 when in the closed position. - Referring now to
FIG. 5 , when thehood 78 is pulled rearward by a user, thebarrel 70 is released from the closed position. In particular, when the user actuates thehood 78, thehood 78 slides rearward on thereceiver 54 and out of engagement with thebarrel 70, thereby allowing thebarrel 70 and theforend 66 to swing about thescrew 68 into the open position shown inFIG. 5 . - In the open position, the
rear end 72 of thebarrel 70 is readily accessible, for instance, so that thebarrel 70 can be serviced and thebreech plug 74 can be removed. - Referring to
FIG. 6 , thehood 78 lies substantially flush with the contours of the muzzle-loading firearm 50. For instance, atop surface 98 of thehood 78 aligns with atop surface 100 of thebarrel 70. In addition, arear surface 102 of thehood 78 aligns with atop surface 104 of thestock 52. - As shown in
FIG. 6 , theconcave surface 64 of theforend 66 abuts theconvex surface 62 of thestock 52. It should be appreciated from the portion of the muzzle-loading firearm 50 shown inFIG. 6 that the receiver (not shown inFIG. 6 ) is substantially encased or housed within thestock 52. - Also as shown in
FIG. 6 , atrigger 106 is mounted to a lower surface of the muzzle-loading firearm 50, below where thereceiver 54 is housed in thestock 52, and extends from an opening formed in thestock 52. Additionally, ahammer 108 is mounted to the rear of thereceiver 54 and extends from an opening formed in therear surface 102 of thehood 78. It should be appreciated that thehammer 108 is in mechanical communication with thetrigger 106 so that thehammer 108 is actuated in response to the actuation of thetrigger 106. - A muzzle-loading firearm having a removable breech plug and the operation of the hammer and the trigger is disclosed in U.S. Pat. No. 7,612,064 to Laney et al., the disclosure of which is incorporated herein by reference.
- Referring to
FIG. 7 , thereceiver 54 defines a pair oflateral holes 110 towards a front end thereof. The lateral holes 110 receive thescrew 68 that retains theforend 66 to thereceiver 54. - The
receiver 54 also defines arecess 112 in atop surface 114 thereof. Therecess 112 receives ablock 116 that is pivotally mounted in therecess 112 by thescrew 68 that retains theforend 66. Theblock 116 releasably attaches to thebarrel 70 on a topside thereof, for instance, via pins 118. Theblock 116 also releasably attaches to aramrod 120 on a bottom side thereof. - Referring to
FIG. 8 , therecess 112 defines an angled limitingwall 122 toward the front end of thereceiver 54. When the muzzle-loading firearm 50 is in the open position, theblock 116 abuts the limitingwall 122, limiting the rotation of thebarrel 70 and theforend 66 relative to thestock 52 and thereceiver 54. - The limiting
wall 122 defines anopening 124 into which anadjustable cap screw 126 is inserted. Thecap screw 126 can be rotated to cause anupward end 128 of thecap screw 126 to protrude from the limitingwall 122 or to retract therein. When theupward end 128 protrudes from the limitingwall 122, the position of theupward end 128 limits the rotation of thebarrel 70 and theforend 66 relative to thestock 52 and thereceiver 54. For example, thecap screw 126 may be fully rotated into thereceiver 54, causing theupward end 128 to abut theblock 116 when the muzzle-loading firearm 54 is in the closed position. In this position, theupper end 128 of thecap screw 126 blocks theblock 116 from pivoting about thescrew 68, thereby locking the muzzle-loading firearm 54 in the closed position. - Referring now to
FIGS. 7 and 8 , theupper portion 82 of thereceiver 54 has thebushing 84 mounted thereto. Thebushing 84 defines ahole 130 therein that receives astriking pin 132. Thestriking pin 132 communicates the action of thehammer 108 to thebreech plug 74. - The
upper portion 82 of thereceiver 54 hasrearward protrusions 134 that extend laterally outward from each side thereof. Therearward protrusions 134 are substantially trapezoidal. - The
upper portion 82 of thereceiver 54 also has forwardprotrusions 136 that extend laterally outward from each side thereof. Theforward protrusions 136 are adjacent to the front facing surface of theupper portion 82 of thereceiver 54 to which thebushing 84 is mounted. - The
top surface 114 of thereceiver 54 has a three-tiered surface. Afirst tier 138 abuts thebarrel 70 when the muzzle-loading firearm 50 is in the closed position. Rearward of thefirst tier 138, asecond tier 140 abuts a portion of thehood 78 and underlies therearward protrusions 134 and theforward protrusions 136. With specific reference toFIG. 7 , rearward of thesecond tier 140, athird tier 142 defines abore 144 with aslit 146 formed in a rear surface of thereceiver 54. Thebore 144 and theslit 146 are sized to receive a portion of the spring-biasedshaft 94 and a portion of thebolt 56 that connects thereceiver 54 to thestock 52. An upper corner of thebore 144 is in fluid communication with a pair of 148, 148 defined in thelateral holes receiver 54. The lateral holes 148, 148 receive a securing pin 150. The securing pin 150 blocks the pin 92 (shown inFIGS. 4 and 5 ) connected to the one end of the spring-biasedshaft 94 from exiting thebore 144, thereby securing thehood 78 to thereceiver 54. - Referring to
FIGS. 9 and 10 , thehood 78 is shown in greater detail. Thehood 78 has a substantially hollow, tapered body with the taperedopening 80 that is fitted to thecircumferential recess 76 of thebarrel 70. - Inward-pointing forward
152, 152 are formed along the inside of the taperedridges opening 80 of thehood 78. The 152, 152 are fitted to contact a forward edge offorward ridges rearward protrusions 134 during attachment and removal of thehood 78 from thereceiver 54. The 152, 152 are also fitted to engage a lower edge offorward ridges forward protrusions 136 when thehood 78 is attached to thereceiver 54. - Inward-pointing
154, 154 are formed along the inside of therearward ridges hood 78. The 154, 154 are fitted to engage the lower edge of therearward ridges rearward protrusions 134 when thehood 78 is attached to thereceiver 54. - The
152, 152 and theforward ridges 154, 154 are separated byrearward ridges 156, 156 that are fitted to slidably receive thegaps rearward protrusions 134 there though during installation of thehood 78 to thereceiver 54. -
158, 158 extend laterally from theWings hood 78. The 158, 158 are substantially triangular protrusions with rounded edges that extend perpendicularly from each side of thewings hood 78. The 158, 158 facilitate the user's ability to engage thewings hood 78, for instance, to slide thehood 78 forward and rearward along thetop surface 114 of thereceiver 54 during the opening and closing of thebarrel 70 and to angle thehood 78 with respect to thereceiver 54 during installation and removal of thehood 78. - Corresponding to the second and
140, 142 of thethird tiers top surface 114 of thereceiver 54, abottom surface 160 of thehood 78 has a two-tiered structure. In particular, acentral tier 162 of thebottom surface 160 of thehood 78 is fitted to thesecond tier 140 of thetop surface 114 of thereceiver 54; and arearward tier 164 of thebottom surface 160 of thehood 78 is fitted to thethird tier 142 of thetop surface 114 of thereceiver 54. Theyoke 90, which is two pronged, depends perpendicularly downward from therearward tier 164. Each prong of theyoke 90 is fitted to abut a lateral side of thebore 144 defined in thethird tier 142 of theupper surface 114 of thereceiver 54 and includes an 168, 168 that receives a respective side of theopening pin 92 attached to the one end of the spring-biased shaft 94 (seeFIGS. 4-5 ). - The
hood 78 is installed to thereceiver 54 according to the following illustrative process. First, the other end of the spring-biasedshaft 94 is mounted to thestock 52. Thepin 92 attached to the one end the spring-biasedshaft 92 is inserted into the 168, 168 of theopenings yoke 90 of thehood 78. Then, thehood 78 is drawn rearward, compressing the spring of the spring-biasedshaft 94, until the 152, 152 of theforward ridges hood 78 slide between theforward protrusions 136 and therearward protrusions 134 of thereceiver 54. The 152, 152 and theforward ridges 154, 154 are slid under therearward ridges forward protrusions 136 and therearward protrusions 134, respectively, for instance, under the force of the spring of the spring-biasedshaft 94. In this position, thehood 78 is spring-biased into a forward position where thehood 78 can securely lock thebarrel 70 in the closed position. Thehood 78 is secured to thereceiver 54 by inserting the securing pin 150 through the lateral holes 148, 148 that are in fluid communication with thebore 144, thereby trapping the spring-biasedshaft 94 and thehood 78 in thebore 144. - Once assembled, the
hood 78 can be reciprocated rearward on thetop surface 114 of thereceiver 54 and out of engagement with thecircumferential recess 76 of thebarrel 70, thereby releasing thebarrel 70 from the closed position. By pivoting thebarrel 70 into the open position, thebreech plug 74 becomes readily accessible for maintenance, service, and replacement. - Preferably, the downward facing portion of the
circumferential recess 76 of thebarrel 70 is sufficiently tapered or sloped so that, when thebarrel 70 is pivoted from the open position to the closed position, thehood 78 is reciprocated rearward by the engagement of thehood 78 with thebarrel 70. Once therear end 72 of thebarrel 70 clears thehood 78, thehood 78 springs forward to engage and secure thebarrel 70. Accordingly, thebarrel 70 can be swung shut and locked in the closed position without independently actuating thehood 78 rearward on thereceiver 54 and out of the path of thebarrel 70. - It should be understood that the foregoing description is only illustrative of the invention. Various alternatives and modifications can be devised by those skilled in the art without departing from the broader aspects of the present invention.
