Different types of firearms can use a plurality of systems to eject the casing of a round and load it with a new round, ready for the user to fire the next round. One such system is the gas-operated reloading. The three most common types of these systems are direct impingement, short stroke piston, and long stroke piston. These systems need to be finely tuned to each specific round that is being used, even of the same bullet diameter. If there is too little gas, then the casing will not be ejected properly, and the firearm could jam. This would interrupt the user from firing another round without first ejecting and/or unjamming the firearm. If there is too much gas, then the walls of the casing could get pressed against the chamber and the friction could cause the casing to get stuck inside without ejecting. Current systems allow the user to adjust the gas that is led back to the bolt carrier, typically by adjusting the gas block volume using a screw. Such systems need to be tuned manually. This process can potentially be time consuming and may not be easy to do when the firearm needs to be used.
So as to reduce the complexity and length of the Detailed Specification, and to fully establish the state of the art in certain areas of technology, Applicant(s) herein expressly incorporate(s) by reference all of the following materials identified in each numbered paragraph below.
U.S. Pat. No. 9,879,931 discloses a multi-caliber machine gun system. The machine gun has different types of ammunition feed trays. When a certain type of ammunition feed tray is attached to the receiver assembly, the receiver assembly can be configured to fire that type of ammunition.
U.S. Pat. No. 10,386,145 discloses a double barrel firearm where each of the barrels can be adjusted. The angular orientation (e.g., azimuth and elevation) of each barrel can be adjusted utilizing two adjustment members mounted on to the barrels.
U.S. Pat. No. 10,458,732 discloses a bolt carrier extension system. The bolt carrier extension system allows the firearm to incorporate elongated upper and lower receivers, such that long-action or other center fire cartridges can be chambered within AR rifles.
U.S. Pat. No. 9,291,415 discloses an adjustable gas key. The gas key contains an inlet and outlet tube, as well as an inner volume. The user can adjust the inner volume with an adjustment device so that the amount of gas being vented, and the amount of gas sent back to the bolt carrier, is changed.
U.S. Pat. No. 8,596,185 discloses an adjustable gas block method and system for a gas operation firearm. The adjustable gas block system adjusts the size of the gas port, and thus the amount of gas, that enters into the gas tube. This is accomplished with a sliding adjustment plate, where the desired gas port is slid into place depending on the amount of gas desired.
U.S. Pat. No. 8,813,632 discloses an adjustable firearm gas block. This gas block contains a threaded bore with a set screw that enters into, and can restrict, the gas channel. As the set screw constricts the gas channel depending on how far the user screws the set screw in. There is also a second bore adjacent to the first threaded bore, which houses a detent plunger, which can lock the set screw into its desired, gas channel restricting, position.
U.S. Pat. No. 7,596,900 discloses a multi-caliber, ambidextrously controllable, firearm. There is an adjustable ejection system, which has a deflector and an ejection port. The deflector can be attached to one of at least two attachment positions, to adjust the size of the ejection port.
U.S. Pat. No. 2,865,256 discloses a compensating device for firearms. The compensating device takes the form of a system analogous to a double acting fluid motor to regulate the gas needed to cycle the firearm. This invention utilizes a single piston.
U.S. Pat. No. 6,901,689 discloses a pneumatic counter-recoil modulator. This is a gas cartridge system that is inserted into the firearm in order to help reduce recoil when the firearm is discharged. The cartridge is pre-loaded with gas from the manufacturer.
U.S. Pat. No. 10,048,029 discloses a firearm with a gas piston system. The system utilizes a gas regulator with a gas purge plug. Excess gas from the firearm's discharge is purged from the system once it reaches a certain threshold.
U.S. Pat. No. 5,900,577 discloses a modular, multi-caliber weapon system. The system can be reconfigured to fire a wide range of different calibers. The reconfiguration is accomplished by changing the following components: barrel, operating rod, recoil spring, and buffer; gas tube, bolt head, firing pin and extractor; and magazine well.
U.S. Pat. No. 8,806,789 discloses a multi-caliber interchangeable rifle bolt system. This firearm can be reconfigured to fire different calibers, by changing out the stock of the weapon. All of the elements necessary to reconfigure the weapon are stored in the stock of the weapon.
U.S. Pat. Pub. No. US 2015/0241149 discloses an adjustable gas key for an autoloading firearm. The gas key is coupled to a moving parts assembly, where it directs gas towards that assembly such that the firearm is cycled. The gas key has an adjustment control, which may be in some form of screw, which can affect the amount of gas directed. There can also be embodiments that allow a certain amount of gas to vent.
U.S. Pat Pub. No. US 2009/0031605 discloses a multi-caliber, ambidextrously controllable, firearm. This is a continuation to U.S. Pat. No. 7,596,900. There is an adjustable ejection system, which has a deflector and an ejection port. The deflector can be attached to one of at least two attachment positions, to adjust the size of the ejection port.
U.S. Pat. Pub. No. US 2015/0226502 discloses a bolt carrier with integral adjustable gas key. This is a continuation-in-part of U.S. Pat. No. 9,291,415. There is a bolt carrier with an integral adjustable gas key. The adjustable gas key includes a tube portion coupled to a base portion. An inlet passage extends through the tube portion and an outlet passage through the base portion. There is also an adjustment device, which adjusts the inner volume of the gas key. The adjustment of the inner volume adjusts the force of action of the bolt carrier.
Applicant(s) believe(s) that the material incorporated above is “non-essential” in accordance with 37 CFR 1.57, because it is referred to for purposes of indicating the background of the invention or illustrating the state of the art. However, if the Examiner believes that any of the above-incorporated material constitutes “essential material” within the meaning of 37 CFR 1.57(c)(1)-(3), Applicant(s) will amend the specification to expressly recite the essential material that is incorporated by reference as allowed by the applicable rules.
The present invention provides among other things a delayed-opposed-piston gas action system.
A delayed-opposed-piston gas action assembly is comprised of a bolt that interfaces with a round in a chamber of a firearm; a bolt carrier that interfaces with the bolt; a gas block that interfaces with a gas port on a barrel; a bolt piston that interfaces with the bolt carrier and the gas block; and a vent piston that interfaces with the bolt carrier and the gas block. The bolt piston will also have a bolt piston cup and a bolt piston spring. The vent piston will also have a vent piston cup and a vent piston spring. After this point, a portion of the expelled gas will be vented. Then, the vent piston spring will act on the vent piston. Then, the vent piston acts on the bolt carrier, causing a casing of the round to be ejected from the firearm. Then, the bolt piston spring will act on the bolt piston. The bolt piston will then act on the bolt carrier. The bolt carrier will then load a new round into the firearm.
When the firearm is discharged, the gas block will direct an expelled gas to the bolt piston cup and the vent piston cup. When this happens, the bolt piston will act on the bolt piston spring, and the vent piston will act on the vent piston spring.
Aspects and applications of the invention presented here are described below in the drawings and detailed description of the invention. Unless specifically noted, it is intended that the words and phrases in the specification and the claims be given their plain, ordinary, and accustomed meaning to those of ordinary skill in the applicable arts. The inventor is fully aware that he can be his own lexicographer if desired. The inventor expressly elects, as his own lexicographers, to use only the plain and ordinary meaning of terms in the specification and claims unless he clearly states otherwise and then further, expressly sets forth the “special” definition of that term and explains how it differs from the plain and ordinary meaning. Absent such clear statements of intent to apply a “special” definition, it is the inventor's intent and desire that the simple, plain and ordinary meaning to the terms be applied to the interpretation of the specification and claims.
For the purposes of this invention, the term caliber references the specific geometry of a round.
The inventor is also aware of the normal precepts of English grammar. Thus, if a noun, term, or phrase is intended to be further characterized, specified, or narrowed in some way, then such noun, term, or phrase will expressly include additional adjectives, descriptive terms, or other modifiers in accordance with the normal precepts of English grammar. Absent the use of such adjectives, descriptive terms, or modifiers, it is the intent that such nouns, terms, or phrases be given their plain, and ordinary English meaning to those skilled in the applicable arts as set forth above.
Further, the inventor is fully informed of the standards and application of the special provisions of 35 U.S.C. § 112(f). Thus, the use of the words “function,” “means” or “step” in the Detailed Description or Description of the Drawings or claims is not intended to somehow indicate a desire to invoke the special provisions of 35 U.S.C. § 112(f), to define the invention. To the contrary, if the provisions of 35 U.S.C. § 112(f) are sought to be invoked to define the inventions, the claims will specifically and expressly state the exact phrases “means for” or “step for, and will also recite the word “function” (i.e., will state “means for performing the function of [insert function]”), without also reciting in such phrases any structure, material or act in support of the function. Thus, even when the claims recite a “means for performing the function of . . . ” or “step for performing the function of . . . ,” if the claims also recite any structure, material or acts in support of that means or step, or that perform the recited function, then it is the clear intention of the inventor not to invoke the provisions of 35 U.S.C. § 112(f). Moreover, even if the provisions of 35 U.S.C. § 112(f) are invoked to define the claimed inventions, it is intended that the inventions not be limited only to the specific structure, material or acts that are described in the preferred embodiments, but in addition, include any and all structures, materials or acts that perform the claimed function as described in alternative embodiments or forms of the invention, or that are well known present or later-developed, equivalent structures, material or acts for performing the claimed function.
The foregoing and other aspects, features, and advantages will be apparent to those artisans of ordinary skill in the art from the DETAILED DESCRIPTION and DRAWINGS, and from the CLAIMS.
A more complete understanding of the present invention may be derived by referring to the detailed description when considered in connection with the following illustrative figures. In the figures, like reference numbers refer to like elements or acts throughout the figures.
In the following description, and for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the various aspects of the invention. It will be understood, however, by those skilled in the relevant arts, that the present invention may be practiced without these specific details. In other instances, known structures and devices are shown or discussed more generally in order to avoid obscuring the invention.
