TECHNICAL FIELD
The present invention relates to the field of firearms; more particularly, to a rack and pinion lever-action rifle.
BACKGROUND OF THE INVENTION
In lever-action firearms a lever located around the trigger is used to load cartridges into the chamber of the barrel when the lever is worked. Most lever-action firearms are rifles.
The lever moves a bolt rearward in the receiver when rotated downward and forward. As the bolt moves rearward, an extractor pulls a spent cartridge from the chamber and propels the empty cartridge either from the top of the receiver or through a port on the side.
While the bolt moves rearward, a new cartridge is pushed from a magazine by a spring-loaded follower and presented to a carrier assembly that then lifts the new cartridge up in line with the bolt to be chambered when the lever is pulled rearward and upward. The rearward motion of the bolt cocks a hammer and engages a sear in a trigger. This prepares the firearm to fire. Once fired, the cycle can be repeated as the lever is operated by a user until the magazine is emptied of all cartridges.
Magazines on lever-action rifles are typically tubular in shape and are located under the barrel. Magazines are sometimes fed through the buttstock. They can also be box or integral box magazines mounted directly under the action.
U.S. Pat. No. 245,700, issued Aug. 16, 1881 discloses a lever-action rifle comprising a swinging lever operating a pivoted arm connected with and moving a carrier, said swinging lever being also connected with a link which carries a pinion traveling in a stationary rack, which pinion moves the bolt to and fro to carry the cartridge from the carrier into the barrel. The swinging lever is also connected with an arm pivoted to a lock used to secure a vertically-swinging breech-block up firmly against the bolt, the latter being adapted to move the breech-block in both directions. A projecting or pivoted piece on the handle of the swinging lever, which strikes against part of the trigger, adapts the arm to be discharged rapidly by the simple movement of the swinging lever to and fro.
U.S. Pat. No. 5,148,619, issued Sep. 22, 1992, discloses a rack and pinion system for a lever-action firearm that provides the rack element as a floating gear and includes a cam lever extension of the lever member. The cam lever extension applies rearward force directly to a bolt and compresses a spring between the lever member and the rack element. After the bolt breaks free from locking lugs, force is applied to the rack element by the lever member through the spring to complete the rearward movement of the bolt.
Existing lever-action designs such as the Marlin Model 336 use large clearances between the tang on the end of a lever and a slot in a bolt to lock the bolt. The Marlin Model 336 and other traditional lever-action rifles cock a hammer on opening the lever.
There is a need for a lever-action rifle with a smoother operation than existing lever-action rifles. There is also a need for a lever-action rifle with simpler safety features than in existing lever-action rifles.
SUMMARY
In accordance with one embodiment of the present invention, a firearm comprises a receiver, a barrel having a chamber at one end and joined to said receiver, a cartridge magazine to contain a cartridge, a sliding bolt with a rack surface and an attached extractor, and a pinion in direct contact with the bolt. A claw on the pinion is configured to deliver a cartridge from the cartridge magazine to the extractor on the face of the bolt when the pinion pivots. A lever member is also connected the receiver with the pivot pin and may alternate between a coupled configuration and a partially uncoupled configuration with the pinion. The coupling of the pinion and the lever member is achieved via a spring-loaded locking pin on the pinion. A decoupling pin releases the pinion from a coupled configuration with the lever member. Also, a bolt pin couples with a locking groove in a sliding bolt cap on the sliding bolt when in a locked position.
A hammer, hammer spring, sear, trigger, and firing pin interact to discharge the firearm. An ejector mounted in the side of the receiver pushes a spent cartridge so that it is ejected out a slot in the side of the receiver.

DETAILED DESCRIPTION
Throughout the following description, specific details are set forth in order to provide a more thorough understanding of the invention. However, the invention may be practiced without these particulars. In other instances, well known elements have not been shown or described in detail to avoid unnecessarily obscuring the disclosure. Accordingly, the specification and drawings are to be regarded as illustrative rather than restrictive. It is to be further noted that the drawing is not to scale.
FIGS. 1-2 show a cross section of a portion of a preferred embodiment of a rack and pinion lever-action rifle. A receiver 10 is the frame or action body of the firearm, and is the housing that contains the mechanism that allows for the discharging of the firearm. A barrel 12 with a chamber 14 at one end is connected to the receiver 10. When the firearm is discharged, a propellant is ignited in the barrel 12, creating rapidly expanding gasses with pressure to force a projectile from the chamber 14 through the interior of the barrel 12 and out of the barrel 12. In a preferred embodiment, a removable cartridge magazine 16 into which cartridges 18 are loaded is attached to the receiver 10. Each cartridge has a rim 18a and a body 18b. The cartridge magazine 16 feeds the cartridges 18, one at a time, to be received by a sliding bolt 20.
The sliding bolt 20 reciprocates relative to the receiver 10 between an in-battery position, as shown in FIG. 1, and a rearward position, as shown in FIG. 2. In a preferred embodiment, a locking groove 24 in a sliding bolt cap 20a on the sliding bolt 20 engages with a bolt pin 26 when the sliding bolt 20 is approximately in the in-battery position, as shown in FIG. 1. In a preferred embodiment, the bottom of the sliding bolt 20 has a rack surface 28 with rack teeth 30 disposed along part of the rack surface 28.
An extractor 32 is located on the face 22 of the sliding bolt 20 and is contoured to receive and support the cartridge 18 when the sliding bolt 20 is approximately in the rearward position, as shown in FIG. 2.
A pinion 34 with a spring-loaded locking pin 36 and with pinion teeth 38 is connected to the receiver via a pivot pin 42, and arranged to mesh with the rack teeth 30 on the sliding bolt 20. When the pinion 34 pivots on the pivot pin 42 from the position shown in FIG. 1 to the position shown in FIG. 2, the pinion teeth 38 interact with the rack teeth 30 and cause linear motion of the bolt 20 from the position shown in FIG. 1 (i.e., the in-battery position) to the position shown in FIG. 2 (i.e., the rearward position). In a preferred embodiment, the pinion teeth 38 are disposed along an arc of approximately ninety degrees on the pinion 34.
A claw 40 is attached to the pinion 34 and configured to engage and extract a cartridge 18 from the cartridge magazine 16 and deliver the cartridge 18 to the face 22 of the bolt 20 and the extractor 32 when the pinion 34 pivots on the pivot pin 42 from the position shown in FIG. 1 to the position shown in FIG. 2.
A lever member 44 is connected to the receiver 10 via the pivot pin 42. In a preferred embodiment, one end of the lever member 44 is contoured so that the lever member may alternate between a coupled configuration, as shown in FIG. 2 and a partially uncoupled configuration, as shown in FIG. 1, with the pinion 34 via the spring-loaded locking pin 36 located on the pinion 34.
In a preferred embodiment, a pair of decoupling pins 46 is affixed to the receiver 10. The decoupling pins 46 are disposed to interact with the spring-loaded locking pin 36 when the pinion 34 pivots from the position shown in FIG. 2 and nears the position shown in FIG. 1, causing the spring-loaded locking pin 36 in the pinion 34 to be moved so that the pinion 34 and the lever member 44 are released from the coupled configuration shown in FIG. 2 to the partially uncoupled configuration shown in FIG. 1.
In a preferred embodiment, the lever member 44 interacts with the bolt pin 26, which is contoured to couple with the locking groove 24 in a sliding bolt cap 20a in the sliding bolt 20. The bolt pin 26 reciprocates towards the sliding bolt 20 and away from the sliding bolt 20 in a motion that is relative to the receiver 10. The motion of the bolt pin 26 causes it to alternate between a locked position when the sliding bolt 20 is in approximately the in-battery position, as shown in FIG. 1, and an unlocked position when the sliding bolt 20 is in approximately the rearward position, as shown in FIG. 2.
A hammer 48 is configured to reciprocate relative to the receiver 10 between a cocked position, as shown in FIG. 1, and an uncocked position, as shown in FIG. 2. The hammer 48 is disposed in relation to the sliding bolt 20 so that the sliding bolt 20 engages the hammer 48 as the sliding bolt 20 approaches the in-battery position, as shown in FIG. 1 from the rearward position shown in FIG. 2, causing the hammer to move into the cocked position from the uncocked position.
A hammer spring 50 is disposed so that motion of the hammer 48 as it approaches the cocked position results in compression of the hammer spring 50.
A spring-loaded sear 52 is pivotally attached to the receiver 10 and disposed to engage with the hammer 48 when the hammer 48 is in the cocked position.
A spring-loaded trigger 54 is pivotally attached to the receiver 10 and disposed to engage with the spring-loaded sear 52. When the trigger 54 is depressed, such as by a person firing the firearm, the trigger 54 pivots and releases the spring-loaded sear 52, which in turn causes the sear 52 to disengage from the cocked hammer 48.
When the sear 52 is disengaged from the cocked hammer 48, the hammer 48 moves under a force exerted by the hammer spring 50 towards a firing pin 56 disposed between the hammer 48 and the barrel 12 until the hammer 48 strikes the firing pin 56.
An ejector 82 is mounted in said receiver 10 and pushes spent cartridges 18 out of the receiver 10 through an ejector opening 84.
In a preferred embodiment, the cartridge magazine 16 further comprises a spring-loaded cartridge pusher 58 that positions the cartridge 18 so that the claw 40 may engage with the cartridge 18 for delivery of the cartridge 18 to the extractor 32.
Turning now to FIGS. 3-5B, the face 22 of the sliding bolt 20 and the extractor 32 in a preferred embodiment can be seen in greater detail.
A pocket 60 on the front of the face 22 has a shoulder 62 to contain the cartridge 18 that is open on one side. This allows the cartridge 18 to be loaded into the bolt face 22 and in front of the firing pin 56 by the claw 40 as the claw 40, which is disposed on the pinion 34, approaches the bolt face 22 as the pinion 34 pivots on the pivot pin 42. At the end of its travel, the claw 40 approaches the bolt face 22 so that a cartridge 18 carried by the claw 40 is moved over the side of the face 22 that does not have a shoulder 62 and deposited approximately in the center of the face 22. A stepped and beveled portion of the extractor 32 comprising a guide ramp 64 and a hook 66 extends out from the bolt face 22 slightly more than the thickness of the rim of the cartridge 18. The guide ramp 64 helps guide the cartridge 18 into position on the bolt face 22 without sticking or binding when the pinion 34 with claw 40 pivot away from the bolt face 22, the hook 66 of the extractor 32 holds the cartridge 18 in the bolt face 22.
A step 68 on a portion of the extractor 32 protruding beyond the bolt face 22 presses against the rim 18a of the cartridge 18. In a preferred embodiment, the extractor 32 is made from spring steel and is under spring tension when a cartridge 18 is engaged with the extractor 32 and the sliding bolt 20 on the bolt face 22. The extractor 32 pushes on the rim 18a of the cartridge 18 so that the opposite side of the rim 18a of the cartridge 18 is pressed against the shoulder 62 of the bolt face 22. This interaction between the extractor 32 the cartridge 18, and the bolt face 22 plus the hook 66 of the extractor 32 securely holds the cartridge 18 on the bolt face 22. This allows the sliding bolt 20 to feed the cartridge 18 into chamber 14 of the barrel 12 in a controlled fashion.
Referring to FIGS. 4B and 5B, the guide ramp 64 of the extractor 32 is contoured so that the extractor 32 is not in contact with the body 18b of the cartridge 18 when the claw 40 is interfacing with the bolt face 22 during delivery of a cartridge 18 from the cartridge magazine 16. The claw 40 is contoured so that it fits between the extractor 32 and the body 18b of the cartridge 18 without interference from the extractor 32 when loading a cartridge 18 into the bolt face 22. The guide ramp 64 helps load the cartridge 18 into place on the bolt face 22. In a preferred embodiment, single cartridge 18 loading directly into the chamber 14 is possible.
Turning now to FIGS. 6-7A, the claw 40 in a preferred embodiment can be seen in greater detail. The claw 40 is configured to engage with and grab the cartridge 18, draw it up in an arc as the lever member 44 pivots, insert the cartridge 18 into the face 22 of the bolt 20, and release the cartridge 18 when the claw 40 pivots away from the bolt face 22 after having deposited the cartridge 18 on the bolt face 22.
The claw 40 has a first prong 70 and a second prong 72 that enable the claw 40 to engage with the cartridge 18 in the cartridge magazine 16. The claw 40 grabs the cartridge 18 from the cartridge magazine 16 in two ways. Catches 74 on the first prong 70 and second prong 72 of the claw 40 engage the rim 18a of the cartridge 18 to pull the cartridge 18 out of the cartridge magazine 16 as the claw 40 pivots away from the cartridge magazine 16 towards the face 22 of the sliding bolt 20. Also, the claw 40, in a preferred embodiment, is, between the first prong 70 and the second prong 72, approximately 0.001″ narrower than the diameter of the cartridge body 18b near the rim 18a. As the claw 40 pivots in an arc from the position shown in FIG. 1 to the position shown in FIG. 2, and encounters a cartridge 18, the first prong 70 and second prong 72 engage the body 18b of the cartridge 18 near the rim 18a and the claw 40 exerts a slight spring pressure on the body 18b. The force of friction due to the slight pressure exerted by the first prong 70 and the second prong 72 of the claw 40 holds the cartridge 18 while the claw 40 pivots toward the bolt face 22. The force of friction is low enough so that the cartridge 18 is held securely but transferred to the bolt face 22 and the extractor 32 with no difficulty when the claw 40 engages with the bolt face 22. The top of the claw 40 pushes the rim 18a of the cartridge 18 into the bolt face 22 where it is latched by the extractor 32. The second prong 72 of the claw 40 is thinner than the first prong 70. The second prong 72 fits between the extractor 32 and the cartridge body 18b. The thickness of the second prong 72 is such that it applies the correct spring pressure on the cartridge 18 without touching the extractor 32. The claw 40 is contoured so that the claw 40 puts the cartridge 18 into the bolt face 22 so that the cartridge 18 is retained on the bolt face 22 by the extractor 32. The claw 40 is contoured to eliminate mechanical interference with the cartridge 18 during the full range of motion of the claw 40 as it pivots together with the pinion 34 to which it is connected. In one embodiment, the claw 40 is detachable from the pinion 34 and may be held into place on the pinion 34 by a claw screw 40a, preferably with an adhesive thread locking compound to eliminate accidental loosening of the claw screw 40a.
In an alternate embodiment shown in FIG. 7B, the claw 40 is pinned onto the pinion with a set of claw pins 40b.
In another alternate embodiment shown in FIGS. 7C-7F, the claw 40 is, attached to the pinion 34 by a dovetail socket 40c on the pinion 34 receiving a dovetail 40d on the claw 40. The dovetail 40d is inserted into the dovetail socket 40c.
In yet another alternate embodiment, shown in FIG. 7G, the claw 40 is an integral part of the pinion 34. The claw 40 and pinion 34 may be cast in this way by manufacturing methods including investment casting, or may be connected by manufacturing methods including welding or brazing.
Turning now to FIGS. 8A-8C, the components that allow the lever member 44 to alternate between a coupled configuration and a partially uncoupled configuration with the pinion 34 can be seen in greater detail. The user rotates the lever member 44 back and up to fully load the cartridge 18 into the chamber 14. When the sliding bolt 20 is all the way forward (i.e., in an in-battery position), the pinion 34 will not move due to engagement of the pinion teeth 38 with the rack teeth 30. The lever member 44 must move further up to push the bolt pin 26 into the locking groove 24 in the sliding bolt cap 20a at the back end of the sliding bolt 20. Such motion is possible when the lever member 44 and pinion 34 are in a partially uncoupled configuration. To alternate between a coupled configuration and a partially uncoupled configuration with the pinion 34, the pivot pin 42 which connects the receiver 10, the lever member 44, the pinion 34, and the spring loaded locking pin 36 function together. Starting when the lever member 44 is in the configuration shown in FIG. 1 and the bolt pin 26 is engaged in the locking groove 24 in the sliding bolt cap 20a in the back of the sliding bolt 20, the lever member 44 is rotated towards the configuration shown in FIG. 2. As the lever member 44 starts pivoting away from the receiver 10, the spring loaded locking pin 36 will slide deeper into a locking notch 76 on the lever member 44, securely coupling the lever member 44 and pinion 34. At this point, the lever member 44 and pinion 34 are one generally rigid assembly. The lever member 44 is cycled down and all the way forward (i.e., to the configuration shown in FIG. 2), then is rotated up and back (i.e., to the configuration shown in FIG. 1). As the lever member 44 gets close to the receiver 10, the sear 52 is engaged in the hammer 48 compressing the hammer spring 50. There is significant pressure on the lever member 44 therefore the lever member 44 must be a generally rigid assembly. At almost the furthest upward travel of the lever member 44, decoupling pins 46 fixed in the receiver 10 engage and push the locking pin 36 forward until the locking pin 36 moves into a decoupling notch 78 on the lever member 44 placing the lever member 44 in a partially uncoupled configuration with the pinion 34. The lever member 44 continues up whereby it pushes the bolt pin 26 into the locking groove 24 effectively immobilizing the sliding bolt 20. It is essential that the depth of the locking notch 76, which is located adjacent to the decoupling notch 78 (beyond the depth of the decoupling notch 78) is deeper than the diameter of the locking pin 36 so that the locking pin 36 can fully engage and securely lock with the locking notch 76 and, in effect with the lever member 44. This is essential to the success of the design. If the lever member 44 and pinion 34 were always in a coupled configuration, engaging the bolt pin 26 in the locking groove 24 would not be possible.
Turning now to FIG. 8D, the components that allow the bolt pin 26 to alternate between a locked position in the locking groove 24 when the sliding bolt 20 is in approximately the in-battery position, as shown in FIG. 1, and an unlocked position when the sliding bolt 20 is in approximately the rearward position, as shown in FIG. 2, are shown in greater detail.
When the sliding bolt 20 is in approximately the in-battery position, a pull-hook 44a disposed on the lever member 44 couples with a pull-hook recess 26a disposed on the bolt pin 26.
As the lever member 44 pivots from the position shown in FIG. 1 towards the position shown in FIG. 2, the pull-hook 44a pulls the bolt pin 26 out of the locking groove 24. Simultaneously, the pull-hook 44a moves gradually out of the pull-hook recess 26a, due to the arc of motion followed by the pull-hook 44a as it travels with the pivoting lever member 44. As the motion continues, the pull-hook 44a eventually completely exits the pull-hook recess 26a. This motion is reversed when the lever member 44 pivots from the position shown in FIG. 2 towards the position shown in FIG. 1, with the lever member 44 pushing the bolt pin 26 into the locking groove 24 and the pull-hook 44a moving into the pull-hook recess 26a.
A bolt pin retainer 26b, disposed in the receiver 10 projects into the pull-hook recess 26a at all times and prevents the bolt pin 26 from dropping out of the receiver 10, even when the pull-hook 44a is no longer in the pull-hook recess 26a.
Referring to FIGS. 1-2, when the firearm is ready for firing, with the hammer 48 and hammer spring 50 in a cocked position and the locking pin 26 in the locking groove 44, a safety feature may be employed by uncocking the hammer 48 and the hammer spring 50 by pivoting the lever member 44 from the position shown in FIG. 1 towards the position shown in FIG. 2 until the bolt pin 26 drops out of the locking groove 24. This will allow the hammer 48 and hammer spring 50 to decock, with the hammer spring 50 expanding without firing the firearm. The sliding bolt 20 with the sliding bolt cap 26a will protrude from the receiver 10 when the hammer 48 is decocked, and the hammer 48 will not protrude from the sliding bolt cap 26a providing for easy assessment of whether the hammer 48 is cocked or decocked.
Turning now to FIG. 8E, a sliding bolt cap 20a is disposed on the sliding bolt 20 and holds the hammer spring 50 in position. In one embodiment, the sliding bolt cap 20a has a screwdriver slot 20b, which can be used to screw the sliding bolt cap 20a into position on the sliding bolt 20 utilizing threads 20c that allow the sliding bolt 20 and sliding bolt cap 20a to be screwed together.
FIG. 8F shows a portion of the receiver 10 with the sliding bolt 20 and sliding bolt cap 20a protruding out of the receiver 10. Here, the hammer 48 is visible in the sliding bolt cap 20a, and is in an uncocked position.
FIG. 8G shows the hammer 48 protruding out of the sliding bolt cap 20a. Here, the hammer 48 is in a cocked position.
FIG. 8H shows some of the details of a sliding bolt cap 20a screwed into a sliding bolt 20, including the screwdriver slot 20b in in the sliding bolt cap 20a and interlocked threads 20c of the sliding bolt cap 20a and the sliding bolt 20.
Alternate embodiments of a bolt pin 26 are shown in FIGS. 8I-8J. As shown in FIG. 8I, the bolt pin 26 may be generally cylindrical in shape. In an alternate embodiment, the bolt pin 26 may be generally rectangular in shape as shown in FIG. 8J, and contoured to engage securely with locking groove 24 shown in FIG. 8H.
Turning now to FIGS. 9A-9D, various embodiments of the extractor 32 are shown. In one embodiment shown in FIG. 9A, the extractor 32 comprises a cantilever leaf spring with a clip 80 for attaching the extractor 32 to the sliding bolt 20.
In an alternate embodiment shown in FIG. 9B, the extractor 132 is a see-saw pivot-type extractor 132 with a pivot point 134 and a coil spring 136.
In another alternate embodiment shown in FIG. 9C, the extractor 232 is a rod cantilever-type extractor 232.
In yet another alternate embodiment shown in FIG. 9D, the extractor 332 is a hinge pivot-type extractor 332 with a hinge point 334 and a hinge coil spring 336.
From the description above, advantages of the invention become evident in that it allows for a smoother operating lever-action rifle than existing lever-action rifles, as well as for simpler safety features than in existing lever-action rifles.
While the invention has been described by reference to various specific embodiments, it should be understood that numerous changes may be made within the spirit and scope of the inventive concepts described. Accordingly, it is intended that the invention not be limited to the described embodiments, but will have full scope defined by the language of the following claims.
