Abstract
Description
- This application claims the benefit of earlier filing date and right of priority to U.S. Provisional Application No. 62/921,809, filed 8 Jul. 2019, the contents of which is incorporated by reference herein in its entirety.
- The present invention relates to automatic firing rifles and machine guns and more specifically it relates to the Bolt Carrier Group (GRP) or the primary mechanism responsible for the automatic firing and ejecting of spent cartridges, as well as the reloading of new cartridges. The entire sequence if often referred to by the industry as the “automatic cycling functioning” in which the BCG is central.
- Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common general knowledge in the field. Other than subtle differences in materials, tolerances, and manufacturing processes, the basic design of the BCG has remained constant and has not significantly changed in several decades.
- In general, the sequence describing the basic operation central to the BCG's role can be described as follows in the following steps. During “feeding”, upon going forward, the bolt strips a round from the magazine. With “chambering” the bolt inserts a round into the chamber. It is at this point that the extractor catches onto the rim of the cartridge. With “locking”, the bolt locks into place in the barrel extension usually by rotating. A cam pin follows a track milled into the bolt carrier and rotates the bolt slightly. With respect to “firing” the sear releases the hammer, which strikes the firing pin (located within the bolt carrier group). This fires the cartridge, which, once the bullet passes the gas port, it sends the gas from the fired cartridge back onto either an actuator rod (in short-stroke and long-stroke piston systems), into a chamber located within the bolt carrier (in expanding gas piston systems), or directly onto the bolt face itself (in direct impingement systems). With “unlocking” the bolt unlocks via the bolt carrier being pushed back, which rotates the bolt. During “extraction”, the bolt, upon unlocking, pulls the cartridge from the chamber. With “ejection” the bolt contains a spring-loaded ejector. During the bolt carrier group's rearward cycle, the ejector ejects the spent casing via the ejection port. At this time, “cocking” occurs as the BCG cycles all the way back, it cocks the hammer, thereby allowing the weapon to be fired again.
- The BCG is then sent forward, feeding another cartridge and repeating the process. The slide on a semi-automatic pistol performs these same functions, albeit with slightly different parts and a different operating system altogether (as most pistols are not gas-operated).
- From a system standpoint, the prior art as it centers around the BCG can be categorized as an open-loop system. The operating parameters across the eight automatic cyclic function sequence are fixed and constrained based on the limitation of the physical attributes of the law of physics that controls them. One such component is the recoil spring which is responsible for buffering the effects of the recoil as the bolt is accelerated rearwards from the expanding gas fed back by the gas tube barrel. The compressed state of this coil as it decompresses sends the slide/bolt forward in the opposite direction again to load the next cartridge to be fired. Using a very strong recoil spring requires more of gas to be fed back to the gas port to create a force strong enough to move the bolt to its full rearwards position thereby lowering the exit velocity of the bullet.
- The trade-off however is that the reload will happen much quicker since the acceleration of the spring as it decompresses and moves the BCG forward is a function of its spring constant. Conversely, using a weak recoil spring may not buffer the energy from the recoil and reload as quickly, but it would not divert as much energies away from the propellant gas providing more of the expanding gas energies to accelerate the bullet to a higher exit velocity.
- Another example regarding the limitation associated with the prior art is that burst rate settings (number of rounds fired in succession from a single pull of the trigger) are typically fixed in number. For example, three (3) or five (5) are typical rather than being a variable setting. This limitation perhaps stems from approaching the design from a purely mechanical implementation. Any adjustability to this particular setting would over complicate any mechanical approach to the point not worth the effort.
- Another disadvantage is found through the following example which illustrates the inefficiencies of the prior art. On certain automatics such as an M249, the bolt travel in excess in some cases. The M249 light machine gun (LMG) is designed to be fed using cartridge loading or belt loading. Belt loading requires more energies to reload and by virtue requires more gas energies and longer travel to mechanically feed each new round. In theory, in the case for magazine loading, the BCG would only require to travel roughly half the distance back, or just enough to allow the cartridge to drop into the chamber. To simplify the design, the prior art in the case of the M249, the bolt goes through the entire rearward range of motion as it travels regardless whether a magazine or cartridge belt is used. This is an obvious point of inefficiency.
- Although strides have been, shortcomings remain. It is desired that an assembly be provided that is increases performance, efficiency, and the reliability of the automatic cycling function.
- In view of the foregoing disadvantages inherent in the known types of bolt carrier group sub-assemblies now present in the prior art, the present invention provides a new approach wherein the same can be utilized for increased the performance, efficiencies, and reliability of the automatic cycling functioning.
- The present invention provides a novel implementation to the BCG operation by incorporating within a firearm frame a microprocessor/microcontroller in combination with an electric power motor, rectilinear reciprocating actuator, and a solenoid controlled firing pin which curtails many of the issues and inefficiencies found in the prior art. The microprocessor is a closed-loop controlled system and provides consistent reliable performance and recovery or avoidance from potential jamming. The microprocessor can compensate for changes in the environment such temperature and debris and detect and recover from jamming. One example of this would have the bolt easily controlled by the microprocessor to halt the bolt and reverse direction if necessary, to eject the bad cartridge for example. Furthermore, the firearm may include biometric systems in that the microprocessor can be used to deploy such functions as biometrics lockout security, diagnostics, automatic sight adjustments and metrics.
- Ultimately the invention may take many embodiments. In these ways, the present invention overcomes the disadvantages inherent in the prior art. The more important features have thus been outlined in order that the more detailed description that follows may be better understood and to ensure that the present contribution to the art is appreciated. Additional features will be described hereinafter and will form the subject matter of the claims that follow.
