Abstract

A trigger mechanism for a gun capable of fully automatic firing comprising an adjustable pneumatic or hydraulic timing device 9 operable to determine the rate of fire of the gun, which device cyclically interrupts bolt 1 shown in position of discharging the ammunition from the gun when trigger 6 of the mechanism is moved to a firing position (as shown). Additionally, the ammunition discharge rate may be substantially constant and determined by the timing device independent of any other weapon characteristics. Recoil of bolt 1 depresses cam hammer 7 and releases second sear 5 to block the bolt until the cam hammer returns in an anti-clockwise direction, controlled by flow of hydraulic or pneumatic fluid in cylinder 9, to re-engage a projection on the cam hammer with a point 8 on the secondary sear. <IMAGE>

Description

FIRE RATE CONTROL SYSTEM The invention relates to a fire rate control system for a gun such as a submachine gun or light machine gun.
The mechanism to be described, allows for the firing mechanism of an open-bolt or closed-bolt S.M.G. or L.M.G.
to be upon firing, momentarily arrested in a cocked condition and then to be released to fire another round after a predetermined and preset lapse of time. Such a mechanism thereby allows the rate of fully automatic fire to be accurately controleed and preset.
The importance of such a mechanism lies in the ability to choose a rate of fire which eliminates the negative effects of the phenomenon known as "climb" or "stitching" common to most S.M.G.'s is use today. Climb is caused by an excessive rate of fire. The weapon does not have sufficient time to return to its original point of aim before each successive round is fired on full auto. The general result is one round on target and thereafter a string of shots movign upwards and off target i.e. no control. Such lack of control over shot placement is obviously both dangerous and very undesirable.
As the requirements of the military and law enforcemei called for lighter and more concealable weapons, the law of physics ensured increasing rates of fire and increasing rates of climb. The rate of fire of S.M.G's currently employed, varies from approximately 600 R.P.M. to over 2,000 R.P.M.
Testing has shown however, that in S.M.G's weighing somewhere between 4.5 and 8 pounds, the phenomenon of climb does not disappear until the rate of fire is brought down below 450 R.P.M. (approximately).
This can be demonstrated by the current model of the BUSHMAN I.D.W. - 9mm S.M.G. which employs an electronic rate control system (see PCT/GB90/01969) set at 420 R.P.M.
The weapon weights 5.7 pounds and does not climb when fired on full auto, even when fired by untrained personnel.
The mechanism to be described is shown as an alternative to the electronic rate control system employed in the BUSHMAN I.D.W. 9mm S.M.G. (see PCT/GB90/01969) and was developed in parallel so as to share as many components as possible between the two versions. A comparison of the two versions would show that except for the rate control units themselves, the majority of the remaining parts are interchangeable between the two models. The advantage of the new system lies in its simplicity and the reduction of moving parts in the trigger mechanism.
Accordingly, the invention provides a trigger mechanism for a gun capable of fully automatic firing comprising a timing device operable to determine the rate of fire of the gun, which device cyclically interrupts means for disharging the ammunition to be discharged from the gun when a physically displacable trigger of the mechanism is moved to a firing position.
Preferably the timing device comprises a hydraulic or pneumatic device operatively connected to a bolt of the gun.
According to a further feature of the invention there is provided a gun having a bolt decelerator.
An embodiment of a rate control mechanism according to the invention will now be described, by way of example only, with reference to the accompanying drawings, in which: FIGURE 1 shows a sectional side elevation view of a trigger mechanism and rate control system according to the invention, in a cocked position; FIGURES 2 to 6 show successive steps in the operation of the mechanism and system shown in Figure 1 during firing.
The trigger mechanism functions as follows. The MAIN-SEAR (4), pivots about SHAFT (11) and engages BOLT (1) at BENT (2). The TRIGGER (6) and SECONDARY-SEAR (5) both pivot about SHAFT (12) and engage each other at FACE (19). The SECONDARY-SEAR (5) engages the BOLT (1) at BENT (3). The CAM-HAMMER (7) pivots about SHAFT (13) and is connected to the RATE CONTROL PISTON (9) at SHAFT (14). The CAM HAMMER (7) engages the SECONDARY-SEAR (5)at POINT (8). The RATE CONTROL PISTON ROD (10) is fixed to the FRAME (16) at SHAFT (15), For semi-automatic fire the CAM-HAMMER (7) would be locked out of engagement with SECONDARY-SEAR (5) by a selector unit (not shown) and would be in a position as seen in figures 5 or 6. For semiautomatic fire disregard the CAM HAMMER (7) and PISTON (9) in those drawings.
Figure 1 shows the weapon cocked and ready to fire. MAIN SEAR (4) is engaged with BOLT (1) at BENT (2). TRIGGER (6) has forced SECONDARY SEAR (5) out of possible engagement with BOLT (1) via contact at FACE (19).
In FIGURE 2, when TRIGGER (6) is pulled, MAIN SEAR (4) is disengaged from BOLT (1). Simultaneously, TRIGGER (6) disengages contact with SECONDARY-SEAR (5) at FACE (19).
SECONDARY-SEAR (5) is now free to engage BOLT (1) at BENT (3) after a round has been fired. The bolt now is free to fly forward via a main spring force (not shown), strip a cartridge from the magazine, and chamber and fire said cartridge as seen in Figure 3.
The force of the exploding cartridge sends the BOLT (1) rearwards, where BOLT (1) is engaged and arrested by SECONDARY-SEAR (5) at BENT (3). When the TRIGGER (6) is released, it engages the SECONDARY-SEAR (5) at FACE (19) and forces the SECONDARY-SEAR (5) to disengage from BENT (3). Simultaneously the MAIN-SEAR (4) has been allowed to come up and is ready to engage the BOLT (1) at BENT (2) at the moment the SECONDARY-SEAR (5) has disengaged from BENT (3). The condition is as seen in Figure 1. The weapon is now recocked and ready to be fired via another pull on TRIGGER (6).
For reaulated full auto fire, the CAM-HAMMER (7) and fluid filled PISTON UNIT (9) are brought into position as seen in Figures 1, 2 and 3. The PISTON UNIT (9) is Figures 1, 2 and 3 is shown at full expansion (via internal spring force) causing CAM-HAMMER (7) to exert a downward force on SECONDARY-SEAR (5) at POINT (8). SECONDARY-SEAR (5) is forced out of possible engagement with BOLT (1).
Figure 1 shows the weapon cocked and ready to fire on reaulated fully automatic fire. Figure 2 shows TRIGGER (6) pulled and MAIN-SEAR (4) just disengaged from BOLT (1) at BENT (2). The BOLT (1) is now free to fly forward, strip a cartridge from the magazine and chamber and fire said cartridge. Conditions would be as in Drawing "C" at that moment.
The explosive forces of the cartridge send the bolt (1) rearwards where bolt (1) then engages cam-hammer (7) as seen in Figure 2 and the bolt (1) cams the cam-hammer (7) completely down as seen in Figure 4 taking cam-hammer (7) out of engagement with secondary-sear (5) at point (8).
Secondary-sear (5) is now free to snap upwards, engaged bolt (1) at bent (3) and arrestn bolt (l)'s forward movement as seen in Figure 5. In Figure 5 cam-hammer (7) has caused rate-control-piston (9) to fully compress against an internal spring force. During compression a check value has opened, allowing the internal fluid to pass freely around the piston head. After the bolt (1) has been arrested by the secondary-sear (5) the rate-control-piston (9) is free to expand. The piston check valve closes and the resistance of the fluid trying to pass the piston head causes the piston to expand at a relatively slow and preset rate. The expanding piston forces the cam-hammer (7) upward and into engagement with the secondary-sear (9) at point (8) as seen in Figure 5.When the rate-controlpiston (9) has fully expanded, the cam-hammer (7) will have forced secondary-sear (5) out of engagement with bolt (1) at bent (3) (as seen in Figure 2) and the bolt flies forward, repeating the sequence. The gun will continue to fire at the preset rate until all ammunition is expanded or until the trigger (6) is released, allowing the main sear (4) to engage the bolt (1).
Rates of fire as low as 100 R.P.M. have been achieved. An infinite control between 'o' R.P.M. and the full natural unregulated rate of the weapon can be achieved by altering the internal functions of the piston and the fluid viscosity.
The rate-control-piston in the BUSHMAN was designed to serve a dual function. The rate-control aspect has been explained. The second function is as a decelerator for the bolt. The camming action as the bolt (1) hits the camhammer (7) and the internal expansion spring within the cylinder (9) were designed to absorb a maximum of energy from the returning bolt. This has allowed for the use of a light weight aluminum breech and a very light weight bolt. All other open bolt weapons rely on a relatively heavy botl mass to absorb energy in an effort to reduce rate of fire and stress on the breech. This large moving mass is what makes traditional open bolt weapons less accurate than closed bolt version.
The rate control devices of this system has taken away the need for a heavy bolt, thereby retaining the simplicity and safety of an open-bolt system, with first shot accuracy comparable to a closed bolt weapon. Of course, where required, the BUSHMAN rate control system can be applied equally well to a closed bolt system.
