FIELD

The present description relates generally to a firearm and methods for manufacture and operation of a firearm.

BACKGROUND AND SUMMARY

Civilian gun owners use firearms for a variety of purposes such as self-defense, hunting, target shooting, competitions, collecting, etc. Breech loading rifles are popular amongst many gun owners due to their quick and reliable cartridge loading action. One such breech-loading rifle that has gained in popularity in recent years is the Martini-Henry rifle. The Martini-Henry rifle is highly sought after and collectable and is likely to continue increasing in popularity. Martini-Henry rifles have in the past, required multiple pins to be knocked out of the action body to breakdown the action. Knocking the pins out requires the use of special tools such as a hammer and punch due to the pin's interference fit, increasing disassembly time and effort. Furthermore, each pin retains a separate component in the action, requiring each component to be precisely aligned during reassembly, resulting in a tedious and laborious reassembly process.

Previous Martini-Henry rifles also include a threaded striker stop and screw for retaining the striker assembly in a desired position. Specifically, the classic Martini-Henry rifle has a stop nut retaining the striker and striker spring in the block. This stop nut threads into the block along with a stop nut locking screw, working against the stop nut and preventing the stop nut from unthreading. To remove the striker and striker spring in the classic Martini-Henry rifle design, two screwdrivers of different sizes are required. It is therefore time consuming to remove the striker, due to the specific tools needed to remove the threaded striker stop and screw, further exacerbating assembly/disassembly difficulties.

Prior Martini-Henry rifles also require a complex action manufacturing process. In prior Martini-Henry rifles, a rounded post included in the action body allows parts of the action to be removed from the action body. However, it is difficult and costly to cast or machine the post into the action body, due to the complex geometric profile of the action body, thereby driving up manufacturing costs.

Additionally, prior Martini-Henry rifle blocks include a pivot pin enclosure mating with a pivot pin. The pivot pin allows the block to move into a loading configuration where a cartridge can be inserted into a rear of the barrel and cocked configuration where a striker pin in the block is aligned with a cartridge in the barrel. However, the pivot pin serves as the sole interface between the action body and the breech. Therefore, the load path resulting from a cartridge discharge travels directly through the pivot pin and then to the action body in such a configuration. The pivot pin may have, at the time when the Martini-Henry rifle was originally designed, been strong enough to receive loads generated by black powder. However, modern smokeless power generates much more force than black powder. As such, Martini-Henry rifles using smokeless powder cartridges may damage the block pivot pin due to the localized load distribution on the pin.

Furthermore, the classic Martini-Henry rifle's lever typically has a catch hook on the butt end of the lever that is captured by an accommodating steel lever catch block mounted in the butt stock. The lever in this classic design has sharp edges on the butt end of the lever that can scrape or scratch a user's hand. The classic design also makes an undesirable noise when the lever is brought into the closed position and as it engages the lever catch block. The catch hook also presents more manufacturing difficulties.

Martini-Henry rifles and other breech loading rifles have also suffered from inaccuracy problems caused by thermal expansion of the barrel. For example, when repeated firearm discharge produces thermal expansion of the barrel, the dimensions of the barrel grow to a point where the barrel impinges against the forearm. When this occurs, the barrel can be forced in the opposite direction of the impingement, causing the impact point of the projectile to move from its zeroed point. The variance of pressure against the forearm can also alter the inherent harmonic vibration of the barrel also causing accuracy issues. Another source of accuracy issues can arise when a forearm is rigidly affixed to both the barrel and the action. When the forearm is attached in this manner, the variation in thermal expansion of the barrel and forearm can work against the action and put undesirable force on the barrel.

The inventors herein have recognized the issues described above and designed a firearm with assembly/disassembly features and methods for firearm manufacturing to at least partially overcome the aforementioned issues. The assembly/disassembly features facilitate fast and efficient assembly and disassembly of the firearm. For example, the firearm described herein may be broken down in a less than a minute when compared to 5-10 minutes for previous Martini-Henry rifles. Additionally, the manufacturing methods increase manufacturing efficiency to drive down manufacturing costs.

In another example, the firearm may include a disassembly latch allowing for efficient removal of the action assembly from the action body. The disassembly latch is positioned at a front side of the action assembly and includes a protrusion mating with a recess in the action body when the disassembly latch is in a latched configuration. In an unlatched configuration, the protrusion in the disassembly latch is spaced away from the recess. In this way, a user is able to efficiently disconnect the action assembly from the action body. Consequently, the firearm may be more quickly assembled and disassembled when compared to previous rifles requiring multiple pins to be knocked out of the action during breakdown. In one example, the disassembly latch may only be actuated when an extractor in the action assembly is in an extraction position. In this way, the likelihood of unwanted disassembly latch actuation is reduced.

The firearm may also include, in one example, a trigger guard support pin separately manufactured from the action assembly and then subsequently press fit into the action body. In this way, manufacturing efficiency of the action body is increased when compared to previous action body designs requiring a post to be cast or machined into the action body.

In yet another example, the firearm may include a removable block support laterally positioned between two walls of the trigger guard. The removable block support is designed to receive firing forces from the block and transfer said forces to the back of the action body. In this way, the removable block support allows forces to be transferred to a stronger area of the action and relieves unnecessary loading on the block pivot pin. As a result, firing forces may be dispersed through a controlled path to alleviate stresses on weaker components. Therefore, the likelihood pivot pin damage, caused by repeated loading, is considerably reduced. The removable block support may be replaced if damaged by an over pressure situation, and may prevent the need to replace the firearm action. The removable block support may also increase manufacturing efficiency by eliminating the step of machining the detail into the inside back of the action.

The firearm may also include a removable striker stop pin securing the striker assembly in a desired position. The removable striker stop pin allows the striker assembly to be more efficiently assembled/disassembled when compared to previous striker assembly designs including a threaded stop pin and screw requiring tools to insert and remove the threaded pin. The removable striker stop pin also increasing manufacturing efficiency by eliminating the need to machine threads into the block and striker stop, if desired.

In another example, the firearm may include a spring loaded catch plunger in the removable block support designed to dampen or in some cases eliminate the impact between the lever and a stock during lever actuation. In this way, unwanted noise and vibration occurring during firearm reloading is reduced and in some cases eliminated.

The firearm may also include a gap between the action body and the forearm to accommodate thermal expansion of the barrel during use of the firearm, in one example. A forearm lug and mounting screw coupling the forearm to the barrel allow the gap to be formed between the barrel and the forearm, in one example. Additionally, the gap between the action body and the forearm may be created by a forearm bracket attached to a front side of the action body and a rear side of the forearm. In such an example, the forearm bracket may also be enclosed via a compliant material (e.g., rubber). The compliant material reduces the change of damage to forearm caused by external forces and provides acoustic dampening during firearm discharge.

It should be understood that the summary above is provided to introduce in simplified form, a selection of concepts that are further described in the detailed description. It is not meant to identify key or essential features of the subject matter. Furthermore, the disclosed subject matter is not limited to implementations that solve any disadvantages noted above or in any part of this disclosure.

DETAILED DESCRIPTION

The following description relates to a firearm, such as a breech loading firearm (e.g., Martini-Henry style rifle). The firearm may be designed with several safety features decreasing the likelihood of unwanted firearm discharge as well as features for efficient assembly/disassembly of the action and other firearm components. The firearm may also be designed with features allowing for quick and efficient assembly/disassembly of the action. Additionally, the firearm may have several design features enabling simplified and efficient manufacturing of the action body and action. The firearm may also have several design features mitigating barrel and action body misalignment caused by thermal expansion of the barrel. The firearm may also include a dampening mechanism for reducing (e.g., eliminating) impacts between the lever and stock during lever cocking.

In one example, the firearm safety features may include a trigger block with a flange on a rear side of the trigger. The trigger block prevents the trigger from being actuated when a lever in the action is in a partially cocked position. In this way, the firearm may only be fired when the lever is in a desired position. As a result, firearm safety is increased.

The safety features may also include a safety mechanism positioned in front of the trigger in a trigger guard. The safety lever includes a safety lever pivoting about a fulcrum and an angled face selectively inhibiting trigger movement. As such, the safety lever, in a first position, blocks the trigger from being actuated and, in a second position, allows the trigger to be actuated. In this way, firearm safety is further increased by allowing a user to selectively deactivate the trigger. Furthermore, by positioning the safety mechanism in front of the trigger and integrating the mechanism into the trigger guard the mechanism can be efficiently actuated, increasing operational efficiency of the firearm.

In one example, the action assembly may include a disassembly latch. When actuated, the disassembly latch allows the action assembly to be efficiently removed from the action body. The disassembly latch may be positioned at a front side of the action assembly. A latching protrusion in the latching assembly engages and disengages with a latching face in the action body. When the latching assembly is disengaged the action assembly pivots about a trigger guard support pin at a rear side of the action assembly. In one example, the action assembly may be removed in one-piece, further increasing assembly/disassembly efficiency.

In another example, the action body may include a trigger guard support pin press fit into an opening in the action assembly. The trigger guard support pin allows the action assembly to be smoothly removed from the action body. Separately manufacturing the trigger guard support pin and pressing the pin into an opening in the action body simplifies action body manufacturing when compared to an action body cast or machined as a single component with a curved post.

In another example, the action body may include a removable block support laterally positioned between sections of a trigger guard. The removable block support is designed to receive firing loads from the block and transfer the loads to the action body. In this way, the removable block support allows forces to be transferred to a stronger area of the action, relieving unnecessary loading on the block pivot pin. As a result, firing forces may be dispersed through a controlled path to reduce the likelihood of block pivot pin damage caused by localized pin loading. Pins may be used to attach the removable block support to the trigger guard, in one example. It will be appreciated that the removable block support may be separately manufactured from the trigger guard. Consequently, manufacturing of the action assembly may be simplified, thereby decreasing manufacturing costs.

In yet another example, the block may include a removable striker stop pin extending laterally through a striker stop to retain the striker stop in a desired position in the block. Providing a removable striker stop pin in the action assembly allows for efficient disassembly of the striker sub-assembly when compared to previous techniques utilizing screws and nuts to retain the striker stop in a desired position.

In another example, the action assembly may include a spring loaded catch plunger in the block support designed to dampen and, in some instances, prevent the lever from directly contacting the stock when the lever is in a cocked position. In this way, unwanted noise and vibration caused by the lever slamming into the stock during lever actuation can be reduced (e.g., eliminated).

In another example, the firearm may be designed with gaps between the barrel and forearm and/or the forearm and the action body. The gaps accommodate thermal expansion of the barrel, to reduce movement between the forearm and barrel, thereby decreasing firing inaccuracies. In such an example, a forearm screw may be used to attach the barrel to the forearm and a forearm bracket may be used to attach the forearm to the action body to create the gaps. In one instance, a compliant bushing (e.g., rubber bushing) may be used to attached the forearm to the action body to reduce the likelihood of damage to the forearm, caused by external forces and provide acoustic dampening during firearm discharge.

Turning now toFIG. 1, a first embodiment of a firearm100is depicted. The firearm100illustrated inFIG. 1is a breech loading firearm and specifically a Martini-Henry style rifle with a variety of updated features. It will be understood that a Martini-Henry style rifle is a breech-loading single-shot lever actuated rifle. The features of the firearm, however, are applicable to other firearm styles and therefore are not limited to only Martini-Henry style rifles, but may be used in a variety of firearms including but not limited to bolt action firearms, semi-automatic firearms, automatic firearms, handguns, shotguns, etc. Furthermore it will be understood that a breech loading rifle is a rifle designed with a loading mechanism enabling a cartridge or shell to be loaded into a chamber adjacent to rear end of a barrel.

An axis system150including three axes: axis152(e.g., longitudinal axis), axis154(e.g., vertical axis), and axis156(e.g., lateral axis), is provided inFIGS. 1-15for reference. The vertical axis may be parallel to a gravitational axis, in one example. Moreover, the axes are perpendicular to one another. However, the axes may have other orientations, in other examples.

As shown inFIG. 1, the firearm100includes a butt102at the rear side104of the firearm. The butt102is attached to a stock106. The butt102and stock106function to secure the firearm100on a user's shoulder. However, other firearm designs have been contemplated such as handheld firearms, rifles without stocks, etc.

The stock106is connected to an action assembly108via a bolt110. However other suitable attachment mechanisms have been envisioned including but not limited to welds, press fit pins, adhesive, clamps, pins and slots, combinations thereof, etc.

The firearm100further includes a barrel112and a forearm114coupled to the barrel. The barrel112includes a housing116whose interior surface117defines a boundary of a bore118. A user may grip the forearm114during use of the firearm. The forearm114and the stock106may be discrete sections spaced away from one another, in one example. While in other examples, the forearm114and the stock106may be formed from a continuous piece of material.

The barrel112is designed to guide a projectile (e.g., bullet, shot, slug, etc.) in a desired direction. It will be appreciated that the projectile may be packaged in a cartridge including propellant (e.g., gunpowder), an ignition device (e.g., primer), and a case. When the firearm100is loaded, the cartridge resides in a chamber120of the barrel's bore118. As such, the cartridge may be inserted into a rear end122of the barrel112, during cartridge loading. When fired, the projectile exits the barrel112at a muzzle (i.e., the front end of the barrel). It will be appreciated that accessories such as a sight, optical scope, laser sight, silencer, etc., may be coupled to the barrel112.

The barrel112is shown attached to an action body123that may be included in the action assembly108. Specifically, the barrel112is shown threaded into the action body123. However, additional or alternative attachment techniques may be used to couple the barrel112to the action body123, such as pins, welds, press fitting, combinations thereof, etc.

The action assembly108of the firearm100is designed to load, lock, fire, extract and/or eject a cartridge from the chamber120. The action assembly108, in the illustrated example, is a breech loading single shot type assembly. That is to say that the firearm is designed to have a single cartridge loaded into the rear of the barrel and is also designed to release a striker124each time a trigger126is pulled and fire the single cartridge loaded in the barrel112. However, the features of the firearm100described herein may be applicable to other types of actions such as single actions (e.g., rolling block actions, hinged block actions, etc.), break actions, bolt actions, repeating actions (e.g., repeating bolt actions, revolving actions, pump actions, lever actions, lever release actions, etc.,) autoloading actions (e.g., blockback actions, recoil actions, gas actions, etc.), etc. A trigger guard129, is also shown inFIG. 1, and is configured to reduce the likelihood of unintended trigger actuation. As such, the trigger guard129at least partially longitudinally encloses the trigger126.

A lever128in the action assembly108allows the firearm100to be placed in a cocked configuration and a loading configuration. Thus, the lever128may be rotated about axis130to place the lever128in the loading position and the cocked position as well as positions there between. The positions there between may be referred to as partially cocked positions. Specifically, to place the lever128in the loading position the handle is moved away from the stock106in a first rotational direction134. On the other hand, to place the lever128in the cocked position a handle132of the lever128is moved toward the stock106in a second rotational direction136opposing the first rotational direction134. The handle132includes an upper surface138facing the stock106as well as a lower surface140facing away from the stock106. Furthermore, the handle132may be curved or otherwise contoured to facilitate ergonomic actuation of the lever128.

During loading of the firearm100, the lever128is moved from the cocked position to the loading position. Cocking the lever128places the action assembly108in a cocked configuration where actuation of the trigger126will cause the firearm100to discharge a projectile.

In the firearm's cocked configuration, shown inFIG. 1, a tumbler142is engaged with a sear144. Therefore, in the cocked configuration actuation of the trigger126releases the tumbler142which in turn actuates the striker124in a block146to ignite a primer in a cartridge and fire a projectile through the barrel112. It will be appreciated that the tumbler142and the sear144may be included in the action assembly108. Additionally, the tumbler142includes an upper extension145mating with an opening147in the striker124. Specifically in the illustrated example, the striker124is in a cocked position and pre-loaded to strike a cartridge in the chamber120. The upper extension145therefore presses against a rear side149of the opening147to retract the striker124into the cocked position.

Additionally, the trigger126may be included in a trigger sub-assembly148of the action assembly108allowing the firearm100to be actuated. On the other hand, in a loading configuration the block146in the action assembly108is moved downward to allow a cartridge to be inserted into a rear end of the barrel112. Thus, in the loading configuration the striker124is not aligned with the barrel112. The action body123also may include an extractor160allowing a spent cartridge to be ejected from the rear end of the barrel112, in some examples. The extractor160functions to engage a flange of a cartridge case to remove the cartridge from the action body. When the block146is rotated to its fully counterclockwise position, the bottom face of the block contacts the extractor160causing the extractor to rotate counterclockwise.FIGS. 38-39illustrate the functional movement of the extractor160, described in greater detail herein.

The stock106may be constructed out of a wooden material (e.g., walnut, maple, myrtle, birch, oak, laminated wood, etc.), a polymeric material, combinations thereof, etc., in some examples. The action assembly108may be constructed out of a metal (e.g., steel, aluminum, etc.), a polymeric material, combinations thereof, etc., in some examples. For instance, certain components may be constructed out of metal while others may be constructed out of a polymer. Still further in other examples, the action assembly108may be constructed solely out of metal. Further in one example, the forearm114may be constructed out of a wooden material (e.g., walnut, maple, myrtle, birch, oak, laminated wood, etc.), a plastic material, combinations thereof, etc. The barrel112may be constructed out of a metal such as carbon steel or stainless steel, in some examples. Additionally, the action body123may be constructed out of a metal (e.g., steel, aluminum, etc.), in one example.

FIG. 1shows the trigger block200, described in greater detail herein with regard toFIGS. 2-7, a trigger safety mechanism1100, described in greater detail herein with regard toFIGS. 11-15, and a disassembly latch1600, described in greater detail herein with regard toFIGS. 16-20.FIG. 1also shows a removable block support2000, described in greater detail herein with regard toFIGS. 23-27, a striker sub-assembly2800, described in greater detail herein with regard toFIGS. 28-29, and a lever stop surface3010, shown inFIGS. 30-31. It will be appreciated that, in one example, all of the aforementioned components are included in the action assembly108. However, in other examples, one or more of the abovementioned components, features, etc., may be omitted from the action assembly108.

FIGS. 2-7show a trigger block200in the trigger126of the firearm100. It will be appreciated that various components in the firearm100have been omitted to allow for viewing of the trigger block200. The trigger block200prevents actuation of the trigger126when the lever128in the action assembly108is in a partially cocked position. Preventing trigger actuation when the lever128is partially cocked increases the safety of the firearm100by reducing the likelihood of unintended firearm discharge.FIGS. 2-7show the tumbler142, the lever128including the handle132, sear144, and trigger126. The lever128acts to move the tumbler142into an engaged position with the sear144. Additionally, the trigger126is configured to release engagement between the sear144and the tumbler142.

The sear144and trigger126are designed to pivot about a common axis202, in the illustrated example. However, in other examples, the sear144and the trigger126may not pivot about a common axis. Furthermore, the sear144is designed to rotate in a clockwise direction by a desired amount (e.g., 5 degrees) independent of rotation of the trigger126, in the illustrated example. The independent rotation allows the trigger block feature to be achieved due to the sear and trigger actuation kinematics. Specifically, the tumbler142is allowed to engage with the sear144when the sear is independently rotated in a clockwise direction with regard to the trigger126. However, it will be appreciated that rotation of the trigger126in a counterclockwise direction causes counterclockwise rotation of the sear144, when the lever128is in a cocked configuration.

The lever128and the tumbler142also pivot about the common axis130. In this way, the compactness of the action assembly108may be increased when compared to rifles with levers and tumblers that separately pivot. However, in other examples, the lever128and the tumbler142may not pivot about a common axis. Additionally, it will be appreciated that rotation of the lever128from a cocked position to a loading position causes rotation of the tumbler142. The lever128generates tumbler142rotation via a top surface of the lower extension210in the lever pushing up on the bottom surface of the tumbler, rotating the tumbler in a counterclockwise direction, shown inFIGS. 3-5.

FIG. 2specifically shows the lever128in a partially cocked position between a fully cocked and a loading position. It will be appreciated that the lever may be placed in different positions between the fully cocked and loading position during lever actuation. In the loading position the lever128moves the block146, shown inFIG. 1, downward such that a cartridge can be loaded into the firearm100through the block. In the fully cocked position the lever128moves the block146, shown inFIG. 1, into a cocked position where the striker124, shown inFIG. 1, is aligned with a cartridge. Thus, the cocking sequence involves moving the lever128counterclockwise into the loading position and then clockwise into the fully cocked position. As depicted inFIG. 2, the trigger block200includes a trigger-blocking flange206positioned on a rear side208of the trigger126. The trigger-blocking flange206is in contact (e.g., face sharing contact) with a lower extension210in the lever128, when the lever is in a partially cocked configuration. The trigger-blocking flange206includes a curved surface212interacting with a front surface214of the lower extension210. It will be appreciated that the curved surface212and the front surface214may be correspondingly contoured to allow for smooth lever actuation.

The trigger-blocking flange206further includes a planar upper surface218and planar lower surface220with the curved surface212positioned there between. Additionally, the trigger-blocking flange206is recessed from a lateral surface222of the trigger126. However, other contours of the trigger-blocking flange206have been contemplated. It will be appreciated that the trigger-blocking flange206inhibits trigger actuation across a range (e.g., a partial range near the lever's fully cocked position, a partial range near the lever's loading position, the full range, etc.) of partially cocked lever positions.

When the lever128and tumbler142are in cocked positions the trigger126can be pulled to initiate firearm discharge. On the other hand, when the tumbler142is in the cocked position and the lever128is in a partially cocked position the trigger is inhibited from being pulled via the trigger-blocking flange206in the trigger block200. Furthermore, when the lever128is in the loading position a user can reload a cartridge for subsequent discharge.

The handle132in the lever128allows a user to actuate the lever. The handle132extends along a length of the stock106, shown inFIG. 1, and is below the stock106. However, other handle132profiles may be used, in other examples. For instance, the handle may retract into the stock or may extend further downward to allow the user to more easily grasp the lever.

FIGS. 3-7show a cocking sequence in the action assembly108to place the tumbler142and the lever128in a cocked position. It will be appreciated that various components in the firearm100and specifically the action assembly108have been omitted to allow for viewing of the tumbler142, lever128, sear144, and trigger126. Additionally, the trigger guard129and a removable block support2000are shown inFIGS. 3-6. The trigger guard129longitudinally encloses the trigger126, in the illustrated example. However, in other examples the trigger guard129may only partially surround the trigger126with regard to the longitudinal direction.

FIG. 3shows the lever128in a cocked position and the tumbler142in a disengaged position where it is not engaged with the sear144. As such, the firearm100is in an inactive configuration and therefore is not prepared for discharge.

When the tumbler142is in a disengaged position, rotation (e.g., counterclockwise) of the lever128towards the loading position from the cocked position causes rotation (e.g., counterclockwise rotation) of the tumbler142. Thus, the tumbler142and the lever128rotate in unison during an initial stage of cocking.

FIG. 4shows further rotation of the lever128and the tumbler142, in the cocking sequence. As such, the lower extension210in the lever128slides along the trigger-blocking flange206. A lower extension400in the tumbler142is laterally offset from the trigger-blocking flange206to avoid interaction between the tumbler142and the trigger-blocking flange206. In this way, the tumbler142may travel through its rotation adjacent to the sear144to allow the tumbler to interact with the sear. However, other tumbler contours have been envisioned.

FIG. 4also shows a lower extension400in the tumbler142pushing the sear144forward such that is rotates in a clockwise direction. Specifically, a front face402of the tumbler142pushes on a rear surface404of the sear144. As previously discussed, the sear144may be designed to rotate in the clockwise direction independent of trigger rotation by a predetermined amount (e.g., 5 degrees). In this way, the tumbler142is permitted to mate with the sear144without influencing trigger position.

As shown inFIG. 5, when the lever128reaches the loading position the tumbler142engages with the sear144, therefore bringing the tumbler into its cocked position. Specifically, a recess500in the tumbler142mates with a protrusion502(e.g., corner) of the sear144. Thus, a portion of the tumbler142sits on top of the sear144preventing release of the tumbler142. In this way, the tumbler142may be held in a cocked position by the sear144. In the cocked position, the tumbler142is prepared to be released by the trigger126. It will be appreciated that release of the tumbler142initiates a discharge event in the firearm100. As shown inFIG. 5, the trigger-blocking flange206continues to interact with the lower extension210of lever128. It will be appreciated that, in the depicted configuration, the trigger is only inhibited from rotating into the firing position when the lever is near its fully cocked position and the striker is aligning with the cartridge's primer as shown inFIG. 2andFIG. 4. When the lever128continues to rotate in the counterclockwise direction to the point shown inFIG. 5the trigger can rotate to the firing position. This design feature allows the trigger to be pulled when the lever is in the loading position. Therefore, the striker and striker spring can be unloaded while the lever is being rotated from the loading position back in the clockwise direction into the block closed position. Additionally, the trigger blocking flange206vertically extends on the back of the trigger to prevent the lower extension210from traveling over the flange206, in the illustrated example. Furthermore,FIG. 5depicts the lever128in the loading position that places the action body in a loading configuration for cartridge reload.

Subsequently, the lever128is rotated back into the cocked position, as shown inFIG. 6.FIG. 6again shows the tumbler142engaged with the sear144. It will be appreciated that inFIG. 6, the trigger-blocking flange206is not actively blocking the lower extension210in the lever128. As such, a gap600exists between the trigger-blocking flange206and the lower extension210in the lever128. Therefore, it will be appreciated that the trigger126is free to be actuated when the lever128is in the cocked position. In other words, when the lever128is in the attitude shown inFIG. 6the trigger-blocking flange206is not impinging on the trigger126, allowing the trigger to be pulled. It will be appreciated that the upper extension145in the tumbler142may be designed to interact with the striker124, shown inFIG. 1, to preload the striker and place it in a cocked position. Specifically, the upper extension145mates with a recess in the striker and cocking of the tumbler retracts the striker to place it in the cocked position. In this way, the action assembly108is prepared for firearm discharge. However, other striker preloading kinematics have been contemplated.

Furthermore, the lever128includes an upper extension602. It will be appreciated that when the lever travels through a cocking sequence the upper extension602interacts with the block146, shown inFIG. 1, to place the block in a loading configuration and a firing configuration.

Furthermore, actuation of the trigger126causes the sear144to rotate, releasing the sear144from the tumbler142. Releasing the tumbler142allows the tumbler to rotate clockwise and release the striker124, shown inFIG. 1, causing the firearm to discharge a projectile.

FIG. 7shows action assembly108after the trigger126has been actuated and placed in a firing position. It will be appreciated that the trigger-blocking flange206in the trigger does not prevent trigger actuation when the lever128is in the cocked position. As shown, the lower extension210of the lever128is in contact with a section700of the trigger126below the trigger-blocking flange206.

As shown, the sear144is rotated clockwise to move the protrusion502of the sear144away from the recess500in the tumbler142. When the sear144is moved away from the tumbler142, the tumbler142will subsequently rotate in a clockwise direction causing the striker124, shown inFIG. 1, in the action assembly108to release and strike a cartridge in the barrel112, shown inFIG. 1.

FIGS. 8 and 9show another view of the action assembly108. It will be appreciated that components in the action assembly108have been omitted to enable viewing of the interface between the sear144and the trigger126.

As shown inFIG. 8, the trigger126and sear144rotate about the common axis202. Additionally, the sear144may be rotated in a clockwise direction independent of the trigger126. That is to say that the sear144may be rotated clockwise by a predetermined amount without conversely rotating the trigger126. Specifically, in one example, the sear144may be rotated by 5 degrees before contacting the trigger126, as previously discussed. In other examples, the free movement between the trigger and the sear may be between 0-15 degrees, 0-10 degrees, 0-8 degrees, etc. The free movement of the sear144accommodates the trigger-blocking feature by allowing the tumbler142, shown inFIG. 6, to engage with the sear144. The free movement of the sear144also facilitates operation of the trigger safety mechanism, described in greater detail herein with regard toFIGS. 11-15.FIG. 9shows a gap900between the sear144and the trigger126. The gap900allows for the free rotation of the sear144.

As shown inFIGS. 8 and 9, the sear144includes a sear collar800extending through a sear recess802in the trigger126. The sear collar800enables sear rotation about axis202. Additionally, the sear collar800acts as a bearing surface for the trigger126to rotate upon. Additionally, it will be appreciated that a pin or a screw may extend through an interior opening804of the sear collar800to retain the sear144and the trigger126in a desired location, in some instances.

A sear spring806is shown attached to a front side808of the sear144and to the trigger guard129. Specifically,FIGS. 8 and 9depict the sear spring806wrapping around the sear collar800and including a first end810in contact with the front side808of the sear144and a second end812in contact with an interior surface814in the trigger guard129. The interior surface814therefore acts as an impingement point for the sear spring806. Moreover, the sear spring806preloads the sear144to allow the sear144to engage with the tumbler142, shown inFIGS. 2-7, via an induced force. In this way, the sear144may be held against the tumbler142, shown inFIGS. 2-7, until it is forced away from the tumbler. In turn, forcing the sear144away from the tumbler142causes release of the striker124, shown inFIG. 1. Additionally, it will be appreciated that the sear spring806does not act on the trigger126. However, the sear144may be spring loaded with other types of springs such as leaf springs, elastomeric materials, etc., in other examples.

FIG. 9also shows a lateral wall902of the sear144interfacing with a lateral side904of the trigger126, in the illustrated example. In this way, the sear144may be axially delimited by the trigger126. However, other sear contours may be used, in other examples.

Additionally, a rear surface906of the sear144is in contact with an upper face908of the trigger126in front of the trigger-blocking flange206. This interface between the sear144and the trigger126causes the trigger to actuate the sear when rotated in the clockwise direction. Additionally, the rear surface906and the upper face908have a planar profile. However, other contours of these surfaces have been envisioned.

FIG. 10shows another view of the action assembly108with selected components omitted to enable viewing of the spring loading feature of the trigger126. As shown, the trigger126is loaded via a coil spring1000and a trigger pin1002. The coil spring1000and trigger pin1002function to urge the trigger back into a cocked position after the trigger is depressed and placed in a firing position. Specifically, in the illustrated example, the coil spring1000surrounds a lower section1004of the trigger pin1002. However, at least a portion of the spring may not enclose the coil spring, in other examples. Spring loading the trigger126via the coil spring1000and trigger pin1002increases the compactness of the trigger mechanism when compared to previous triggers loaded with leaf springs. As a result, the compactness of the action assembly108is increased. As shown, the spring1000and trigger pin1002include a bottom end1008in contact with the trigger guard129to allow for spring compression. However, other spring retention features may be used, in other examples.

FIG. 10also shows the trigger126including a sear recess802allowing the sear144, shown inFIG. 9, to be positioned therein when the trigger sub-assembly148is assembled. In this way, the sear may be compactly arranged with regard to the trigger126, thereby reducing the profile of the trigger sub-assembly, when compared to previous firearm designs having separate sears and triggers. However, triggers without sear recesses may be used, in other examples.

FIGS. 11-15show the trigger safety mechanism1100designed to inhibit actuation of the trigger126when the mechanism is placed in a “safe” configuration. Conversely, when the trigger safety mechanism1100is placed in a “fire” configuration trigger actuation is permitted. It will be appreciated that the trigger safety mechanism1100is included in the action assembly108. However, in other examples, the trigger safety mechanism1100may be omitted from the action assembly108. The trigger safety mechanism1100overcomes a number of packaging challenges in the firearm. For instance, the difficulty with putting a safety button in the front of the trigger guard is the lack of available space in the area in front of the trigger. The extractor (when in the extracted position) shown inFIG. 18) may require almost all of the available area. Attempts to modify the extractor/block relationship were found to be complicated and unpractical. To create more room, a flat trigger spring, found in previous Martini-Henry rifles, was replaced with the spring loaded plunger1406. Other difficulties getting a mechanism between the safety button and the trigger include a motion direction change between the safety button and the trigger. The illustrated trigger safety is formed as a single assembly. The safety lever1112toggles between the safety button and the front of the trigger creates the interface. To elaborate, the angled surfaces1116and1118create the space and lack thereof to allow the trigger to rotate or block the trigger from rotating. The safety lever1112is captured under the lever interface1110and the bottom surface of the extractor160, shown inFIG. 1, and may require no other method of containment other than its nesting in the fulcrum opening2404, shown inFIG. 24, if desired.

The trigger safety mechanism1100is positioned in front of the trigger126, allowing the mechanism to be easily accessed. Consequently, the safety's operation efficiency may be increased. For instance, the trigger safety mechanism1100may be actuated by the forefinger of the user's shooting hand. However, safety mechanism layouts facilitating actuation of the mechanism by other fingers have been envisioned. As described herein, the front side of the firearm is a side of the firearm including the muzzle and the rear side of the firearm is a side of the firearm including a stock, butt, and/or handle.

Furthermore, the trigger safety mechanism1100may be at least partially integrated into the trigger guard129, shown inFIG. 1. That is to say, a housing of the trigger guard129may at least partially enclose the trigger safety mechanism1100. In this way, the compactness of the action assembly108may be further increased.

FIG. 11shows the trigger126pivoting about the pivot axis202. The trigger126is shown including a front side1102and the rear side208. The front side1102includes a curved surface1104allowing for ergonomic trigger actuation. Moreover, the rear side208of the trigger126includes a curved surface1106. However, the trigger may include other curvatures, in other examples. The trigger126further includes lateral surfaces1108. In the illustrated example, the lateral surfaces1108are planar. However, in other examples the lateral surfaces may curve inward or outward, or have other suitable contours.

The trigger126includes a lever interface1110interacting with the safety lever1112to allow for actuation of the trigger when the trigger safety mechanism1100is in the fire position. Conversely, the lever interface and safety lever interact to inhibit actuation of the trigger when the trigger safety mechanism is in the safe position. It will be appreciated that the safety mechanism1100is in the fire position inFIG. 11.

The safety lever1112includes a rear end1114having an angled surface1116interacting with an angled surface1118in the lever interface1110of the trigger126to facilitate the aforementioned safety functionality. Thus, in the safe position the angled surface1116is in contact with the angled surface1118shown inFIG. 11andFIG. 14. However, in other examples there may be a small separation between the angled surfaces when the mechanism is in the safe configuration, in other examples. Additionally, the angled surface1116and the angled surface1118may have a substantially corresponding (e.g., identical) angle measured from a horizontal axis1119, in some embodiments. For instance, the angled surface1116and/or the angled surface1118may be arranged at a 10 degree angle, 15 degree angle, 20 degree angle, between 10-30 degrees, etc. The angle1150of the angled surface1118is depicted inFIG. 12. The angle1152of the angled surface1116is depicted inFIG. 14.

Continuing withFIG. 11, the lever interface1110is also positioned in front of and above the trigger's axis of rotation202, in the illustrated example. However, other lever interface1110positions are possible. Additionally, the lever interface1110tapers in a forward direction. However, other lever interface profiles have been contemplated.

The safety lever1112pivots about a fulcrum1120. In the depicted example, the fulcrum1120is near the center of the lever. However, the fulcrum1120may be positioned closer to the rear end1114or a front end1122of the safety lever1112, in other examples. Furthermore, the fulcrum1120may be parallel to the axis154(e.g., the vertical axis). However, other orientations of the fulcrum have been contemplated. The safety lever1112includes curved sections1124adjacent to the fulcrum1120, in the illustrated example. The curvature of the safety lever1112allows the lever to be pivoted about the fulcrum1120. It will be appreciated that the curved sections1124of the safety lever1112may mate with a fulcrum opening2404in the trigger guard129, shown inFIG. 24, to facilitate rotation of the lever. However, in other examples, a pin extending through the fulcrum may allow for lever rotation.

The safety lever1112further includes a top surface1126, a bottom surface1128, and lateral side surfaces1130. In the illustrated example, the aforementioned surfaces are planar. However, other surface contours have been contemplated.

A portion of the front end1122of the safety lever1112mates with a detent1132in a safety button1134. To elaborate, the detent1132includes lateral faces1136interacting with lateral side surfaces1130of the safety lever1112.

The safety button1134includes lateral sides1138allowing the button to be laterally slid into a “safe” position and a “fire” position which in turn places the safety lever in the safe position and the fire position, respectively. The safety button1134is in the fire position inFIG. 11. Thus, the trigger safety mechanism1100is in the fire configuration, inFIG. 11.

It will be appreciated that the safety button1134may extend through the safety button opening2402in the trigger guard129, shown inFIG. 24, to allow the lateral sides1138of the button to be actuated. It will also be appreciated that the safety lever1112may be positioned in fulcrum opening2404in the trigger guard129, shown inFIG. 24. In this way, the trigger safety mechanism1100may be compactly integrated into the trigger guard. As a result, a desired profile of the action assembly108can be achieved.

FIG. 12shows another perspective view of the trigger safety mechanism1100. InFIG. 12the trigger safety mechanism1100is in the fire configuration allowing the trigger to be pulled. The angled surface1118in the lever interface1110in the trigger126is again illustrated. Likewise, the rear end1114of the safety lever1112including the angled surface1116, is also illustrated. A gap1200exists between the angled surface1116of the safety lever1112and the angled surface1118of the lever interface1110. The gap1200allows the trigger126to rotate to initiate firearm discharge in the action assembly108. Thus, the gap1200accommodates rotation of the trigger to disengage the sear144, shown inFIG. 1, from the tumbler142, shown inFIG. 1.

FIG. 13shows a top view of the trigger safety mechanism1100, shown inFIG. 11. Again, the trigger safety mechanism1100is in the fire configuration. In the fire configuration, one of the lateral faces1136in the detent1132of the safety button1134is in face sharing or near face sharing contact with one of the lateral side surfaces1130in the safety lever1112.FIG. 13again shows the trigger126including the lever interface1110with the angled surface1118spaced away from the angled surface in the rear end1114of the safety lever1112.

Additionally, the lateral side surfaces1130in the safety lever1112are parallel to one another, in the example illustrated inFIG. 13. However, non-parallel lateral surfaces have been contemplated. Curved sections1124of the safety lever1112are also shown inFIG. 13.

Furthermore, the lateral faces1136of the detent1132in the safety button1134are arranged at an angle1300with regard to one another. The angle1300may be between 5 and 30 degrees, in one example. However, other suitable angles or angle ranges have been contemplated. In this way, the detent1132is shaped to accommodate rotational movement of the safety lever1112.

FIG. 14shows the trigger safety mechanism1100in the safe position. It will be appreciated that the safety button1134may be pushed in a direction1400to rotate the safety lever1112into the safe position. Conversely, pushing the safety button1134in a direction1402, opposing the direction1400, rotates the safety lever1112to place the lever in the fire position. The safety button1134therefore travels along axis1404when actuated.

In the safe position, the angled surface1118of the lever interface1110in the trigger126is in face sharing or near face sharing contact with the angled surface1116in the rear end1114of the safety lever1112. Thus, the gap between the angle surfaces is reduced (e.g., eliminated), preventing the trigger126from being actuated. However, when the firearm includes the trigger block200, shown inFIG. 2, the lever needs to be in the cocked position to allow the firearm discharge. As such, two conditions may need to be met to allow firearm discharge, in such an example, (i.e., first condition: trigger safety mechanism in the fire position, second condition: lever in cocked position). As such, the likelihood of unintended discharge of the firearm is significantly decreased, thereby increasing firearm safety. However, in other examples, the firearm may not include the trigger block200, shown inFIG. 2, or the trigger safety mechanism1100, shown inFIG. 14.

A safety plunger1406is also shown extending from a bottom side1408of the safety button1134. The safety plunger1406functions to laterally guide the safety button1134in the trigger guard, during button actuation. The plunger1406is shown including a reduced diameter portion1407compactly accommodating the integration of a spring around the plunger. However, other plunger profiles may be used, in other examples.

Additionally, the safety button1134has a generally cylindrical shape, in the illustrated example. However, in other examples, the safety button may have a tapered shape, rectangular shape, square shape, etc.

The safety button1134includes recessions1410in the lateral sides1138to provide texture in the button to assist in actuation of the button. However, in other examples, the recessions1410may be omitted from the button design or other texturing may be provided on the lateral sides of the safety button1134.FIG. 14also shows the sear recess802.

FIG. 15shows another view of the trigger safety mechanism1100. A plunger detent slot1500is shown mating with the safety plunger1406. The plunger detent slot1500acts as an indexing mechanism (e.g., keyway) in that the safety plunger1406(e.g., spring loaded safety plunger) is the key that allows the safety button1134to slide between the safe and fire positions while also keeping the safety button indexed, preventing the button from rotating. In other words, the plunger detent slot1500guides the safety button1134through the transition between the safe and fire positions while also preventing rotation of the safety button. As shown, the plunger detent slot1500includes two extended depth indents1502at opposing ends of the slot1500. The extended depth indents function to retain the safety button1134in the fired or safe position until a user intends to move the safety button between the fire and safe positions. Furthermore, the plunger detent slot1500is curved, in the illustrated example, to provide smooth button actuation. However, other profiles of the plunger detent slot1500have been contemplated. Additionally, the safety plunger1406is loaded via a safety plunger spring1504. It will be appreciated that the safety plunger1406and the safety plunger spring1504reside in a safety plunger recess2400of the trigger guard129, shown inFIG. 24.FIG. 15also shows the trigger126and the safety lever1112.

FIG. 16shows a view of the action assembly108with the disassembly latch1600. It will be appreciated that selected components in the action assembly108have been omitted to enable viewing of the disassembly latch1600and corresponding components.

The disassembly latch1600is designed to allow for efficient removal of the action assembly108from the action body123. Therefore, the disassembly latch significantly increases breakdown efficiency of the action assembly and action body when compared to previous firearm designs requiring multiple pins to be knocked out of the action assembly via a hammer to break down the assembly. Conversely, reassembly of the action may also achieve increased efficiency by using the disassembly latch1600. Furthermore, the disassembly latch1600can be actuated without the use of tools, in some examples, further simplifying action assembly breakdown. Specifically, in one example, the disassembly latch1600allows the action assembly108to be removed in one piece. As such, a user may quickly break down the firearm for inspection, cleaning, repair, etc. However, in other examples, removal of the action assembly108subsequent to disassembly lever actuation may involve removing multiple sections of the action assembly108.

The disassembly latch1600is rotatable about an axis1602and is spring loaded via a spring1604. The spring therefore keeps the latch in a latched position. Rotation of the disassembly latch1600in a first direction1606places the disassembly latch1600in an unlatched position. On the other hand, rotation of the disassembly latch1600in a second direction1608opposing the first direction1606transitions the latch into a latched position. It will be appreciated that the disassembly latch1600is in the latch position inFIG. 16. In the latched position, a latching protrusion1610in the disassembly latch1600is mated with a latching face1612in the action body123. Mating between the latching protrusion1610and the latching face1612allows the action assembly108to be retained in the action body123.

FIG. 16also shows the trigger guard stop face1614retaining the trigger guard129in desired position. In this way, the trigger guard129may be positioned in a desired location in the action body123. It will be appreciated that a rear side1616of the trigger guard129may be held in place via a trigger guard support pin1618. Thus, the trigger guard stop face1614and the trigger guard support pin1618function to secure the trigger guard129and more generally the action assembly108in place with regard to the action body123.

The spring1604encloses a pin1620(e.g., lateral pin) of the disassembly latch1600. A first end1622of the spring1604is retained by a spring detent1624in the extractor160. A second end1626of the spring1604is retained by a shelf1631above the rear surface1630) in the disassembly latch1600.

FIG. 16shows the extractor160in a firing position. In the firing position a holding protrusion1628of the extractor160prevents rotation (e.g., clockwise rotation) of the disassembly latch1600. As such, the holding protrusion1628in the extractor160is in face sharing or near face sharing contact with the rear surface1630of the disassembly latch1600. In this way, the likelihood of unintended actuation of the disassembly latch1600may be reduced. However, it will be appreciated that in other examples, the extractor160may be designed such that the disassembly latch1600may be actuated when the extractor is in the firing position. However, in other embodiments, the action assembly108may not include the extractor160.

An extractor pin1632is also shown inFIG. 16. The extractor pin1632allows the extractor160to rotate about a central axis of the extractor pin1632. Furthermore, the extractor pin1632may be removed subsequent to release and removal of the action assembly108. In one specific example, the extractor pin1632may be removed without the use of special tools.

FIG. 16also shows the upper extension602in the lever128and the block146. The block146includes a lever extension recess1634mating with the upper extension602of the lever128. Specifically, the lever extension recess1634includes a cocked portion1636and a loading portion1638. When the lever128is in the cocked position, as is the case inFIG. 16, the upper extension602is located in the cocked portion1636of the lever extension recess1634. On the other hand, when the lever128is in the loading position the upper extension602is located in the loading portion1638. When the lever128is moved from the cocked position to the loading position the upper extension602moves into the loading portion1638causing the block146to rotate (e.g., rotate in a clockwise direction) about a block pivot pin1640. In this way, the block146pivots downwards to allow a cartridge to be guided into the chamber120, shown inFIG. 1.FIG. 16also shows a lever pin1642allowing the lever128to pivot about the axis130.

Furthermore, the action assembly108inFIG. 16is in a discharge position where the assembly is configured to initiate projectile discharge responsive to a trigger pull. To elaborate, in the discharge position the striker sub-assembly2800, shown inFIG. 28and described in greater detail herein, may be aligned with a cartridge in the barrel. Conversely, in a loading position (e.g., reloading position), the action assembly108is arranged to enable cartridge removal and/or replacement from the rear chamber of the barrel.FIG. 18shows the action assembly108in the loading position where the block146pivots down, allowing a user to access the barrel chamber.

FIG. 17shows an expanded view of the extractor160, the disassembly latch1600, and the trigger guard129. As shown, the holding protrusion1628in the extractor160prevents rotational movement of the disassembly latch1600. Thus, the holding protrusion1628is in contact with the rear surface1630of the disassembly latch1600. The spring detent1624in the extractor160is also shown inFIG. 17. It will be appreciated that the extractor160and the block146are in the cocked position inFIG. 17. Therefore, unwanted latch actuation when intending to discharge the firearm may be avoided. However, in other examples, the extractor160may not block movement of the disassembly latch1600.

FIG. 17also shows the trigger guard stop face1614in the action body123mating with a portion of the trigger guard129. Additionally,FIG. 17shows the latching protrusion1610in the disassembly latch1600mating with the action body latching face1612in the action body123.FIG. 17also shows the pin1620about which the disassembly latch1600pivots.

FIGS. 18-20illustrate a sequence where the disassembly latch1600is actuated and the action assembly108is removed from the action body123. It will be appreciated that such a sequence may be implemented by a user without the use of tools, if desired. Consequently, the action assembly108may be quickly and efficiently removed from the action body, allowing for cleaning, repair, etc., of the action assembly.

Specifically,FIG. 18depicts the extractor160placed in the extracted position. In the extracted position the holding protrusion1628in the extractor160is moved away from the rear surface1630of the disassembly latch1600such that the latch can freely rotate (e.g., rotated in a clockwise direction). It will be appreciated that movement of the lever128into the extracted position places the extractor160and the block146in the extracted position. As previously discussed, in the extracted position the block is rotated (e.g., clockwise rotated) such that a front side1802of the block146drops down and extracts a cartridge.

FIGS. 38-39show the extractor160in the loading and extracted positions, respectively. Specifically, as shown inFIG. 38a cartridge3800is positioned in the chamber120. On the other hand, inFIG. 39fingers3900in the extractor160urge the cartridge3800rearward out of the chamber120to facilitate cartridge removal. Returning toFIG. 18also illustrating the latching protrusion1610in the disassembly latch1600mating with the latching face1612in the action body123.FIG. 18also depicts the trigger guard stop face1614limiting movement of the trigger guard129.

InFIG. 18, the upper extension602in the lever128mates with the loading portion1638of the lever extension recess1634in the block146. The interaction between the upper extension602and the loading portion1638causes the rotational movement of the block146into the loading position. Thus, counterclockwise rotation of the lever128causes clockwise rotation of the block146about the block pivot pin1640.FIG. 18also shows the trigger guard support pin1618.

FIG. 19shows the disassembly latch1600rotated into the unlatched position. The pin1620retaining the disassembly latch1600in the trigger guard129allows the latch to pivot. In the unlatched position, the latching protrusion1610in the disassembly latch1600is spaced away from the latching face1612in the action body123. It will be appreciated that the spring1604may be loaded to resist movement of the disassembly latch1600into the unlatched position to allow for efficient re-engagement of the disassembly latch1600. After the disassembly latch1600is placed in the unlatched position the action assembly108may be rotated in a clockwise direction to allow the action assembly to be removed from the action body123.FIG. 19also shows the extractor160and the trigger guard129engaged with the trigger guard stop face1614.

FIG. 20illustrates the action assembly108and the action body123subsequent to disassembly latch1600disengagement and rotation of the action assembly108. As shown, the removable block support2000includes a concave surface2002spaced away from the trigger guard support pin1618. Subsequent to rotation of the action assembly108may cause the assembly to drop out of the action body123to facilitate inspection, cleaning, repair, etc., of the action.

FIG. 20additionally depicts a cocking indicator2004. The cocking indicator2004is designed to give the operator of the firearm a visual indicator as to when the striker and striker spring are preloaded and the firearm is cocked.

FIGS. 40-41show the action assembly108in the cocked and fired configurations, respectively. As shown, the cocking indicator2004moves up and down. Therefore, in the cocked configuration the cocking indicator2004is visible by the user. On the other hand, in the fired configuration, the cocking indicator2004is hidden from view. Consequently, a user can quickly identify when the action is in the cocked configuration or the fired configuration. In other examples, the cocking indicator may be omitted from the action assembly.

FIG. 20also shows a trigger screw2006securing the trigger126and sear144to the trigger guard129. However, in other examples a removable pin may be used to secure the trigger to the trigger guard.

Additionally, the trigger safety mechanism1100is shown inFIG. 20. As previously discussed, the trigger safety mechanism1100includes the user actuatable safety button1134. Actuation of the safety button into the safe position causes actuation of the safety lever1112which blocks actuation of the trigger126. The safety plunger1406included in the trigger safety mechanism1100is also shown inFIG. 20.

FIGS. 21-22are images of a manufacturing sequence of the action body123. Specifically,FIG. 21shows an example of the action body123without the trigger guard support pin. A support pin opening2100is provided in the action body123to allow insertion of the trigger guard support pin therein. The support pin opening2100laterally extends through the action body123and between opposing lateral sides2102of the action body. However, other support pin arrangements may be used, in other embodiments.

FIG. 22shows an example of the action body123with the trigger guard support pin1618inserted into the support pin opening2100, depicted inFIG. 21. It will be appreciated that the trigger guard support pin1618may be coined after insertion into the support pin opening2100, shown inFIG. 21, in some examples. A manufacturing method for the action body123is shown inFIG. 35and described in greater detail herein.

FIGS. 23-27show illustrations of the removable block support2000in the action assembly108. Specifically,FIG. 23shows a perspective view of a portion of the action assembly108. The removable block support2000is laterally positioned between sections2300(e.g., lateral sections) of the trigger guard129. A plurality of pins2302attach the removable block support2000to the trigger guard129, in the illustrated example. To elaborate, an upper pin2304extends through an upper opening2306to attach the removable block support2000to the trigger guard129. Additionally, a lower pin2308extends through a lower opening2310. Providing a plurality of pins in the action assembly secures the removable block support2000to the trigger guard129. This connection between the removable block support2000and the trigger guard129allows the firing load (e.g., substantially all of the firing load) to be transferred through the removable block support to the back of the action when compared to previous Martini-Henry rifle designs. As a result, the likelihood of action assembly damage caused by overloading is reduced. It will be appreciated that a single pin or more than two pins may be used to attach the removable block support to the trigger guard, in other examples. The plurality of pins2302are cylindrical in shape. However, other pin contours have been envisioned. For instance, the pins may include chamfered ends, tapered ends, etc. Further in other examples, additional or alternative attachment techniques between the removable block support2000and the trigger guard129, have been contemplated such as screws, dovetails, keys, clamps, etc.

Additionally, the block pivot pin1640is shown connecting the block146to the trigger guard129. The block pivot pin1640extends through an opening in the block146. It will be appreciated that the block pivot pin1640allows the block146to be rotated about an axis2312to place the block in the firing position, shown inFIG. 23, or in a loading position. As previously discussed, in the loading position an upper surface2314of the block146guides a cartridge into the chamber120in the firearm100, illustrated inFIG. 1. As shown inFIG. 23, the upper surface2314is curved with regard to the longitudinal and lateral axes to allow the cartridge to be smoothly guided into the action body123, shown inFIG. 16. However, other contours of the block146have been contemplated.

FIG. 23also depicts a curved surface2316mating with the trigger guard support pin1618, shown inFIG. 16. Thus, the curved surface2316holds the back of the action assembly securely in the action body123.

FIG. 24shows a cross-sectional view of the action assembly108with a portion of the trigger guard129removed to reveal the contours of the removable block support2000. It will be appreciated, that the trigger guard129and action body123shown inFIG. 24is in cross-section.

Again, the plurality of pins2302connecting the removable block support2000to the trigger guard129, are shown. Additionally, the block pivot pin1640and the trigger guard support pin1618are illustrated.

FIG. 24also shows the safety plunger recess2400and the safety button opening2402, in the trigger guard129. The safety plunger recess2400functions to limit the movement of the safety plunger1406, shown inFIG. 15. Additionally, the safety button opening2402guides lateral movement of the safety button1134, shown inFIG. 15.

FIG. 24also shows the fulcrum opening2404in the trigger guard129. The fulcrum opening2404retains the fulcrum of the safety lever1112, depicted inFIG. 14.

Furthermore, the plurality of pins2302and the block pivot pin1640, shown inFIG. 24as well as the extractor pin1632, the pin1620, and the lever pin1642, shown inFIG. 16, may be designed to be efficiently removed from the action assembly108. For instance, a user may use a finger or a bullet tip to push the pins out (e.g., laterally out) of the action assembly. As such, the aforementioned pins may have a decreased interference fit between the corresponding openings due to the lateral walls2406of the action body123that retain the pins in place when the action assembly108is assembled with the action body123. In some specific examples, the interference fit between the pins and the openings may be substantially eliminated due to the lateral walls of the action body retaining the pins when the firearm is assembled. In one use-case example, there may be approximately 0.001 inches (in) of clearance on the pins so they can be removed without tools. Further in some examples, the two pins that hold the removable block support to the trigger guard may have slight interference as the removable block support does not need to be removed for cleaning. As a result, assembly/disassembly efficiency is further increased. For instance, the action assembly may be torn down for cleaning, repair, etc., and quickly reassembled without the use of tools and/or with a cartridge.

FIG. 25illustrates a side view of the action assembly108shown inFIG. 24. The removable block support2000includes block indent2500mating with a curved section2502of the block146adjacent to the block pivot pin1640. The mating allows loads generated during cartridge discharge in the firearm to be transferred from the block146to the removable block support2000and then subsequently to the action body123. In this way, firing loads may be transferred to a stronger part in the action assembly108when compared to previous Martini-Henry rifles transferring loads from the block to the block pivot pin. Consequently, the strength of the action assembly is increased.FIG. 25also shows the action body123, trigger guard support pin1618, and trigger guard129.

FIG. 26shows another side view of the action assembly108. Again, the block146, removable block support2000, the action body123, and the block pivot pin1640are illustrated. The force2600transferred through the block146into the block pivot pin1640and then the removable block support2000and then the action body123, is indicated inFIG. 26.

FIG. 27depicts a view of the removable block support2000and the block146in the action assembly108. The pins are removed in the view shown inFIG. 27.FIG. 27shows the openings2306and the opening2310without the pins inserted therein. A block pivot pin opening2700is also depicted inFIG. 27.

FIGS. 28-29show the striker sub-assembly2800in the block146of the action assembly108where a portion of the block146is cut-away to reveal the sub-assembly. The striker sub-assembly2800is designed to be placed in a cocked position and a discharged position. The striker sub-assembly2800is shown in a discharged position inFIGS. 28 and 29. In the discharged position, the striker124is not pre-loaded via the striker spring2802. On the other hand, in the cocked position the striker124is pre-loaded and readied for firing. As previously discussed, the upper extension145in the tumbler142, shown inFIG. 1, interacts with the striker sub-assembly2800to place the sub-assembly in the cocked and discharged positions. Specifically, the tumbler142, shown inFIG. 1, may interact with an opening147, shown inFIG. 1, in the striker124to retract the striker when the tumbler is cocked.

FIG. 28illustrates the striker spring2802longitudinally delimited by a striker flange2804and a front surface2806of a striker stop2808. The striker spring2802also circumferentially surrounds a body2810of the striker124. In this way, the striker spring2802may be compactly integrated into the striker sub-assembly2800. However, other striker pin arrangements may be used, in other examples.

A striker stop pin2812is also shown inFIG. 28extending through an opening2814in the striker stop2808. The striker stop pin2812and corresponding opening2814may be sized to allow the striker stop pin to be removed by hand during striker sub-assembly disassembly. Specifically, in one instance, a user may press on the striker stop2808and/or use a bullet tip to press on the striker stop pin2812to remove the pin, if desired. In this way, the speed at which the action assembly108can be broken down and re-assembled is increased, when compared to previous striker assemblies utilizing screws to retain the striker stop in a desired location in the block.

FIG. 29shows an isometric view of the striker sub-assembly2800in the block146of the action assembly108. Again, the striker stop pin2812, striker stop2808, striker spring2802, and striker124, are illustrated.

FIGS. 30-31show the removable block support2000with components for dampening cocking action in handle132of the lever128. In particular, a set screw3000loaded via a spring3002is shown positioned in a channel3004in the removable block support2000. A catch plunger3006loaded via the spring3002mates with a detent3008in the upper extension602of the lever128when the lever is in the cocked position, as shown inFIG. 30. The removable block support2000also includes the lever stop surface3010in contact with the upper surface138of the lever handle132, as shown inFIG. 30. The lever stop surface3010and the spring loaded catch plunger3006, shown inFIGS. 30-31, work in conjunction to reduce noise and vibration in the firearm during lever actuation. Specifically, the lever stop surface3010is profiled such that contact between the lever and the stock106, shown inFIG. 1, are inhibited. Additionally, the spring loaded catch plunger3006dampens the lever128during lever actuation, thereby reducing noise experienced during lever cocking. Additionally, the axis130about which the lever128pivots, is shown inFIGS. 30-31. The catch plunger3006and the detent3008function to hold the lever128up in the block closed position. Consequently, the problem of a noisy lever/butt catch design found in previous Martini-Henry rifles may be remedied (e.g., eliminated).

FIG. 30shows the lever128in the cocked position (e.g., fully cocked) whileFIG. 31shows the lever128in a loading position. In the loading position, shown inFIG. 31, the lever handle132is spaced away from the lever stop surface3010in the removable block support2000.

FIGS. 30-31show the openings2306and2310in the removable block support2000designed to receive pins. Additionally, a curved surface3012interacting with the rear of the block146, shown inFIG. 29, is also depicted inFIGS. 30-31.

FIG. 32illustrates the interface between the barrel112, forearm114, and the action body123in the firearm100. It will be appreciated that due to the configuration of the firearm100the action body123and forearm114may be attached to one another. Specifically, a forearm bracket3200connects the action body123to the forearm114. The forearm bracket3200is at least partially surrounded via a compliant bushing3201(e.g., rubber bushing). Thus, the compliant bushing3201receives the forearm bracket3200and allows for some forward/backward movement between the bushing and the bracket. The compliant bushing may be constructed out of 90 shore rubber, in one example, to provide desired dampening characteristics. However, outer suitable compliant bushing materials have been contemplated such as plastic, phenolic laminate, etc.

The compliant material reduces the chance of damage to the forearm114caused by external forces (e.g., dropping the firearm) as well as provides acoustic dampening during firearm discharge. The forearm114is attached to the barrel112in the firearm100. An attachment apparatus3202is used to attach the forearm114to the barrel112. In the illustrated example, the attachment apparatus3202includes a forearm mounting lug3204and a forearm screw3206threading into the forearm mounting lug. However, other types of attachment apparatuses have been envisioned. The forearm mounting lug3204extends through an opening3208in the forearm114and includes a first end3210attached to an outer surface3212of the barrel112.

The forearm mounting lug3204, shown inFIG. 32, sets a gap3300between the barrel112and the forearm114, as shown inFIG. 33. The gap3300accommodates for thermal changes in the size of the barrel during use of the firearm. As a result, changes in the relative position between the barrel112and the forearm114can be reduced, thereby improving firearm accuracy.

The forearm bracket3200sets a gap3302between the forearm114and the action body123, as shown inFIG. 33. The gap3302functions to accommodate for changes in the size of the action body123and the stock106, shown inFIG. 1, caused by thermal changes in the components. In this way, misalignment between the action body123and the forearm114may be reduced, thereby increasing firearm accuracy.

FIG. 34is an isometric view of the section of the firearm100, depicted inFIG. 33. Again the action body123, barrel112, and forearm114are illustrated. The compliant bushing (e.g., rubber bushing) is omitted inFIG. 34at3400. As shown inFIG. 34, the forearm bracket3200has a rectangular shape that protrudes into the compliant bushing. The bracket's rectangular geometry prevents the rear portion of the forearm114from rotating on its lengthwise axis. However, other forearm bracket shapes may be used, in other examples.

It will be appreciated that the gaps3300and3302, shown inFIG. 33, may be particularly useful when the forearm114is formed from wood due the wood's volumetric change caused by changes in temperature and/or moisture content. However, as previously discussed, the forearm may be constructed out of other suitable materials.

FIG. 35shows a method3500for manufacturing a trigger guard in a firearm. It will be appreciated that the method3500may be used to manufacture the trigger guard in the firearm discussed above with regard toFIGS. 1-34. However, in other examples, the method3500may be used to manufacture other suitable trigger guards. Additionally, at least a portion of the method3500and the other methods described herein may be implemented via manufacturing apparatuses. The manufacturing apparatuses may be equipped with controllers including code stored in memory (e.g., non-transitory memory) executable by a processor to carry out the steps, actions, etc., described with regard to the method(s). It will also be appreciated that a portion of the steps in method3500as well as the other methods described herein may be manually implemented, in some instances.

At3502the method includes manufacturing a trigger guard support pin. In one example, the trigger guard support pin may be cast, machined, 3-D printed, etc. Further in one example, the pin may be cylindrical. However, other pin shapes may be used, in other examples.

Next at3504the method includes manufacturing an action body with a support pin opening. It will be appreciated that the support pin opening may have a profile allowing the trigger guard support pin to be inserted therein. The action body may be cast, machined, 3-D printed, etc.

At3506the method includes fitting the trigger guard support pin in the support pin opening. For instance, the trigger guard support pin may be press fit into the support pin opening. However, other suitable techniques for fitting the trigger guard support pin into the support pin opening have been contemplated.

At3508the method may include coining the trigger guard support pin on each lateral side of the pin. Coining involves precision stamping where the pin is subjected to a sufficiently high stress to induce plastic flow on the surface of the material. Coining has several benefits such as reducing surface grain size and hardening the surface of the pin while allowing metal deeper in the pin to retain its ductility and toughness and enlarging the lateral sides of the pin producing an extremely tight and tough interference fit between the pin and the action body. In other examples, step3508may not be included in the method.

At3510the method may include grinding and polishing the trigger guard support pin and the action body. In this way, the interface between the pin and the action body may be smoothed. However, in other examples, step3510may be omitted from the method.

Method3500allows the trigger guard support pin to be separately manufactured from the action body and then subsequently fitted into the action body. As a result, manufacturing efficiency of the action body may be increased when compared to an action body with a curved trigger guard support cast or machined therein. As a result, the cost of manufacturing the action body is driven down.

FIG. 36illustrates a method3600for manufacturing a trigger guard and removable block support. It will be appreciated that the method3600may be used to manufacture the trigger guard in the firearm discussed above with regard toFIGS. 1-34. However, in other examples, the method3600may be used to manufacture other suitable trigger guards.

At3602the method includes manufacturing a removable block support. Manufacturing the removable block support may include machining, casting, combinations thereof, etc., the removable block support. The removable block support may include openings sized to receive pins.

Next at3604the method includes manufacturing a trigger guard separate from the removable block support. Manufacturing the trigger guard may include machining, casting, combinations thereof, etc., the trigger guard. The trigger guard may include two lateral walls spaced away from one another. The gap between the lateral walls is sized to mate with the removable block support. Additionally, the trigger guard may include an opening that is lined up with the openings in the removable block support.

Next at3606the method includes attaching the removable block support to the trigger guards via a plurality of pins extending through openings in the trigger guard and the removable block support. For example, a user may push the pins into the pin openings. Method3600allows the removable block support to be efficiently manufactured in conjunction with the trigger guard to decrease firearm manufacturing costs.

FIG. 37depicts a method3700operating a firearm. The method may be implemented via the firearm discussed above with regard toFIGS. 1-34. However, in other examples the method3700may be implemented using another suitable firearm.

At3702the method includes placing the lever in an extracted configuration. Thus, the lever may be rotated away from the stock to allow for rotation of the block downward to allow the firearm to be in the cartridge extracted position, shown inFIG. 18.

At3704the method includes depressing the disassembly latch. Depressing the disassembly latch rotates a latching protrusion in the latch away from a latching face in the action body. As such, the action assembly may be moved away from the action body.

At3706the method includes rotating the action assembly. In this way, the front of the action assembly may drop out of the action body, allowing for rapid and efficient removal of the action assembly.

At3708the method includes removing the action assembly from the action body. Removing the action assembly may include moving the removable block support away from the trigger guard support pin. As previously discussed, the action assembly may be removed as a single unit, in some examples. Consequently, action breakdown in the firearm may be simplified to increase firearm assembly/disassembly efficiency. Method3700therefore allows for quick and efficient disassembly of the action from the body. Furthermore, it will be appreciated that to assemble the action body with the action the method may be carried out in reverse.

As used herein, the terms “approximately” and “substantially” is construed to mean plus or minus five percent of the range unless otherwise specified.

It will be appreciated that the configurations and/or approaches described herein are exemplary in nature, and that these specific embodiments or examples are not to be considered in a limiting sense, because numerous variations are possible. For example, the above technology can be applied to various types of rifles and other firearms. The subject matter of the present disclosure includes all novel and nonobvious combinations and sub-combinations of the various features, functions, acts, and/or properties disclosed herein, as well as any and all equivalents thereof.
