| 164 | Weapon system with short recoil impulse averaging operating group | US13562078 | 2012-07-30 | US08919238B2 | 2014-12-30 | David Steimke; Glenn Rossier |
| A weapon system includes a receiver and an operating group with a barrel extension arranged to axially translate relative to the receiver. In the firing condition, the op-rod assembly and bolt assembly are driven by the drive spring such that the round is guided into the chamber and the op-rod assembly and bolt assembly are locked to the barrel extension and a forward momentum of the op-rod assembly is imparted to the operating group and the round is fired. A portion of an impulse stops the forward momentum of the operating group. In the recoil condition, the operating group is driven rearward by the remaining portion of the impulse, the gas accelerator imparts additional rearward momentum to the op-rod assembly and bolt assembly and stops rearward momentum of the barrel and barrel extension, and the op-rod assembly and the bolt assembly are stopped by the drive spring. | ||||||

| 175 | TOTABLE, SPRING-BIASED, TOGGLE-ACTION FIREARM | US11672519 | 2007-02-07 | US20080000128A1 | 2008-01-03 | Cory Newman |
| A hyper velocity firearm has a downwardly-hinging toggle action. The toggle action incorporates at least one coiled torsion spring that is incorporated in at least one pivot of the toggle. A first embodiment of the firearm employs two torsion springs. A second embodiment employs a single adjustable-tension torsion spring. Tension is adjustable without disassembly of the toggle mechanism. A third embodiment employs a horizontally-oriented compressible coil spring positioned above the toggle to bias the toggle. In the pre-discharge configuration, the toggle of the present invention is about 3 degrees from a straight angle linkage, with a negative degree angle representing an over-center condition. The toggle action is compact and reduces recoil and muzzle lift when the firearm is discharged. | ||||||

| A weapon having a barrel (3) supported in a cradle (2) for axial recoil movement, and having a breech block wedge (7) displaceable, transversely to the barrel axis (6) by a control unit (11) connected to the cradle and acting on a piston rod (8). The control unit (11) includes a spring-loaded shift rod (13) aligned with the piston rod (8), a spring-loaded control rod (15) aligned with a control cam (10) secured to the breech ring (4), and a detent pawl (17) that can be pivoted by a cam (16) from a blocking to a release position. The piston and shift rods (8, 13) are disposed such that during forward motion of the barrel (3), the breech block wedge (7) is already opened by axial displacement of the rods (8, 13) before the control cam (10) displaces the control rod (15). | ||||||
| 178 | Automated projectile firing weapon and related method | US09441195 | 1999-11-16 | US06343536B1 | 2002-02-05 | Glenn E. Rossier; Larry W. Hayes; David L. Steimke; Victor Forrester |
| An automatic projectile firing weapon and a related method for absorbing the recoil force of an automatic projectile firing weapon are disclosed. The weapon includes a barrel assembly that is slidably mounted in a receiver, biased by an operating spring, and engageable with a main sear. A gas operated bolt assembly is slidably mounted within the barrel assembly and is driven by a bolt spring. A trigger is provided to release the main sear and allow the operating spring to move the barrel assembly forwardly in the receiver. There is further provided a buffer connected between the receiver and the barrel assembly to dampen the velocity of the barrel assembly to ensure the barrel assembly is moving at a predetermined maximum velocity when a round is fired at a predetermined firing position. The recoil energy from the fired round is absorbed mainly by the forward motion of the barrel assembly and in part by the operating spring and buffer. In this manner, the peak recoil load to the receiver is minimized and the weapon operates at its actual firing rate from the first shot. | ||||||
| 179 | Firearm, in particular a hand firearm | US77010 | 1998-10-22 | US6129000A | 2000-10-10 | Wolfgang Schmid |
| A firearm, in particular a hand firearm is proposed having a displaceable barrel (23) and a locking mechanism between a bolt carriage (22) accepting the barrel and a guide rod (26) coupled to the barrel (23), wherein the unlocking is effected through rotation of this guide rod (26) | ||||||
| 180 | Breech locking system for self loading firearms | US241501 | 1988-09-07 | US4915011A | 1990-04-10 | David E. Smith |
| A self loading firearm of the locked breech, short recoil pistol type has a barrel and a breech block slide provided with a separate locking block accommodated between the underside of the barrel and the upper surface of a movable trigger guard. The locking block is provided with means for positively locking the barrel to the slide during the high pressure period of the firing cycle of the firearm and means for enabling release of the slide from the barrel during the remainder of the firing cycle. Means described for permitting release of the locking block comprise a rotary catch which is rotatable between a position to hold the locking block in its barrel retaining position and a position in which the locking block is able to release the barrel. The rotary catch is movable axially between a position in which it is rotatable and a position in which it is non-rotatable, the locking block normally being held in its non-rotatable position by the hold open means and being released from that position when the hold open means is in its operative position to hold the slide fully retracted from its forward firing position. | ||||||
