The present invention relates to firearms, specifically to multi-caliber weapon systems.
In the related art, it has been known to use ammunition for firearms offered in numerous bullet calibers, with casings of various dimensions. Various rounds can be grouped together into families based on similar case lengths and diameters. Each round is shaped and sized for a particular firearm, rifle or group of rifles and will perform best in similar rifles to what it was designed for.
Shooters generally select a firearm on the basis of a round size and price. Rounds are similar to screwdrivers, in that not every sized screwdriver is applicable to every situation. For example, the round used to humanely take an elephant would be inappropriate for hunting rabbits and vice versa. Further, in combat operations, weapon systems are optimized for different situations and therefore combatants may have need of a great variety of weapon systems during different missions/deployments.
When a round is chambered in a rifle (e.g. right before it is fired), there are two parts of the firearm that are in contact with the round: the chamber and the bolt face. The bolt face is the structure that pushes the round for yard into the chamber and serves as the backing that holds the round there while it is fired. It has a recess that fits, like a glove, the backside of the round. The chamber is a block of material that is shaped to fit the rest of the round like a glove to hold the round in place with the bullet of the round pointed into the barrel of the firearm. Because the fit of these parts is so close and tight, one is generally not able to use different shape/sizes of ammunition in the same firearm. As an example, one can typically use 38 Special cartridges with a .357 Magnum firearm. In another example, one can generally use the same bolt face for both a 300 Blackout headstamp and a 5.56 mm NATO headstamp. However, such mix-and-match usage is generally rare and problematic. Therefore, it has been desirable to have multiple rifles in different calibers for use during different bunting seasons or other purposes.
However, the cost of firearms limits the number of shooters to a few who possess a range of firearms capable of firing every round available. As a result, many shooters would like to have a single rifle capable of accepting a multitude of different round sizes that could be used in a variety of situations. As an example, some hunters go on elaborate expeditions to take a specific animal that requires a round in a certain caliber range and take that animal early in the trip. The hunter then may wish to enjoy the rest of the trip hunting a different animal that requires a different caliber than the first. As a result, the typical hunter would have to pack multiple rifles and would be limited to an animal that has a size that corresponds to the guns that were packed and that were in season. As a result, there is a need for one rifle that is configurable to accept a variety of caliber/gauges sizes.
Some improvements have been made in the field. Examples of references related to the present invention are described below in their own words, and the supporting teachings of each reference are incorporated by reference herein:
U.S. Pat. No. 4,920,678, issued to Brown, discloses an improvement for a caliber conversion kit for semi automatic and automatic firearms to allow the use of smaller caliber ammunition within. The conversion kit comprises the replacement of the bolt, barrel and magazine clip of the existing firearm so that the firing speed and thus the action or feel is similar to a standard non modified firearm having larger caliber ammunition.

A bolt assembly is slidably disposed within a bolt recess defined in the receiver breech block and barrel. The bolt includes a firing pin slidably disposed therein, the firing pin being, selectively actuatable by the trigger assembly when the receiver is in the engaged disposition. A chamber for receiving a ammunition cartridge therein is defined in the receiver and is disposed with respect to the firing pin such that actuation of the firing pin from a cocked position to a firing position ammunition cartridge to discharge the cartridge, the interchangeable upper receiver assembly being interchangeable with a primary upper receiver assembly of the hand held weapon.
U.S. Pat. No. 7,685,757, issued to Rohrauer, discloses a rifle comprising a housing, a barrel anchored thereon and a forearm extending below the barrel. The barrel is anchored by a fastening element which extends through a cross hole of the housing. The forearm has at least one axial projection that detachably engages into a seat of the housing. The cross hole for anchoring the barrel and the seat for fastening the forearm intersect and the forearm comprises a Snap-in recess for the fastening element to Snap in when the barrel is anchored.
U.S. Pat. No. 8,307,575, issued to Battaglia, discloses a rifle assembly includes a central chassis having a vertically aligned opening and a pair of slots extending from the side walls into the opening. An action has a pair of projections engageable with the slots in the chassis and is removably securable within the chassis. The action is insertable into and removable from above the chassis, with the action axis at an angle to the chassis axis, to engage the respective action and chassis slot and projection. The action is rotatable with respect to the chassis upon engagement of the respective action and chassis slot and projection to align the axes of the action and chassis and lock the action to the chassis against rotation and removal. A resilient material is disposed between the chassis and action to load the action to the chassis with a force in excess of recoil force of the action.
U.S. Pat. No. 8,397,416, issued to Laney et al., discloses a multi-caliber firearm has a breech sleeve connecting a barrel to a receiver and a stock. The stock includes a forward V-block and a rearward V-block. Each of the V-blocks defines a V-cut along a top portion and a through hole substantially aligned with the cross-sectional center of the V-block. The forward V-block extends through a cutout portion of the receiver and into the breech sleeve. The breech sleeve is fastened to the stock through the through hole in the forward V-block to provide a rigid connection between the stock and the breech sleeve. The receiver is fastened to the stock through the through hole in the rearward V-block to provide a rigid connection between the receiver and the stock.

It is understood that the above-described embodiments are only illustrative of the application of the principles of the present invention. The present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiment is to be considered in all respects only as illustrative and not restrictive. The scope of the invention is, therefore, indicated by the appended claims rather than by the foregoing description. All changes which come within the meaning and range of equivalency of the claims are to be embraced within their scope.
For example, although the figures illustrate a separate bolt and bolt face, the bolt and bolt face may be one piece. More, the rear end of the bolt may be threaded so that the bolt and bolt face may be removed together.
It is also envisioned that the bolt and bolt face may each include markings that one lines up evenly with the bolt and bolt face, respectively, to verify that the bolt face is aligned correctly with respect to the bolt. Likewise, a slot may be milled into the bolt face and along the length of the bolt. The slot may enable an ejector tab to contact a head stamp. As a result, the multi-caliber weapon system may include a variety of bolt and/or bolt face sets to couple to the bolt-carrier of the weapon for use with multiple caliber, cartridges, and shells.
It is expected that there could be numerous variations of the design of this invention. An example is that there may be many different combinations of barrels, chambers, bolts, and bolt faces coupled to the frame body to allow for lots of variation in cartridges and shells used with the multi-caliber weapon system.
Further, while a rifle is illustrated, it is understood that there may be non-rifle embodiments of the present invention, such as but not limited to pistols/revolvers, musket loaders, and the like.
Finally, it is envisioned that the components of the device may be constructed of a variety of materials, such as, but not limited to: plastics, metals, wood, glass, leather and rubber.
Thus, while the present invention has been fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiment of the invention, it will be apparent to those of ordinary skill in the art that numerous modifications, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly and use may be made, without departing from the principles and concepts of the invention as set forth in the claims. Further, it is contemplated that an embodiment may be limited to consist of or to consist essentially of one or more of the features, functions, structures, methods described herein.
This invention claims priority under 35 U.S.C. § 120, to the U.S. Non-Provisional patent application Ser.
