THE PREFERRED EMBODIMENT The rifle shown in FIG. 1 contains a burst firing mechanism. With each pull on the trigger, three rounds of ammunition are rapidly fired in. succession through the single barrel. The mechanism includes:
1. a coaxial actuating rod and piston, revolver, and bolt;
2. a double and symmetrical actuating cam in the receiver including the stock which controls the actuating rod and thereby the revolver and the bolt;
3. a magazine which provides three rounds simultaneously to the bolt;
4. a continous forward movement of the actuating rod to strip and chamber three rounds concurrently, and to eject three cases concurrently; and
5. a continuous rearward movement of the actuating rod to fire three rounds sequentially and to extract three cases concurrently.
The rifle comprises a receiver 10 which includes a shoulder stock portion 12, a pistol grip portion 14, and a trigger guard portion l6,joined to a gun barrel 18 integral with a gas cylinder 20, by a coupling nut 22.
An acutating piston 24 slides within the cylinder 20 and is mounted to the forward end of an actuating rod 26, which rod passes through a revolver drum 28 and a gun bolt 30, and whose aft end is pinned to an actuating cam follower support 32 by means of an actuating cam follower 34 which is disposed through a diametral bore in the support and the rod. One end 36 of the follower rides in a shallow cam track 38 and the other end 40 rides in a deep cam track 42 formed into the inner wall ofa longitudinal bore in the receiver. The rod has three longitudinally spaced apart keys 44, 46 and 48 projecting radially therefrom at 90 included angles from the longitudinal axis, a long fourth key 49 aligned with the key 44, and a ball catching concavity 50.
An actuating gas port 52 provides a conduit for gas between the forward portion of the bore of the gun barrel and the forward portion of the bore of the gas cylinder. The aft end of the cylinder has a gas vent port 54.
The revolver drum I8 is disposed in a bore 29 of the receiver, and has three longitudinally extending, parallel, 90 radially spaced apart chambers 56, 58, and 60; three, longitudinally diverging, 90 radially spaced ejection tunnels 62, 64, and 66; and three, longitudinally extending, parallel, 90 radially spaced apart keyways 68, 70 and 72 in a longitudinal bore 74 which will pass the actuating rod 26. An integral annular hoop 76 is provided on the aft end of the revolver 28 for additional strength over the chambers, and is interrupted between the chambers to form annular castellations. Each chamber includes an aft enlarged diameter 78 to accommodate the projectile and its rifling band, and a forward L-seal 82 to provide a gas seal between the chamber and the bore 83 of the barrel 18.
The gun bolt is disposed in a bore 84 in the receiver, coaxial with the bore 29, and is substantially cylindrical with a longitudinal bore 85 which will pass the actuating rod 26. Within the bore are two full length keyways 86 and 88, a blind keyway 90; and a transverse bore 92. The bore 92 is partially blind at one end to provide a lip 94 which permits a ball 96 to project but not to depart from the bore 92. The bolt has a front face 97 from which three extractor lips 98, 100, and 102 project radially at 90 included angles and are spaced from an annular shoulder 104. A firing pin actuator cam track 106 is formed into the outer periphery of the bolt as shown in FIG. 12.
A main spring 108 is also disposed in the bore 84 and is captured between the cam follower support 32 and a plug 110.
A single firing pin assembly 114 is disposed in a longitudinal bore 116 in the receiver 10. The firing pin assembly includes an actuator block 118 having a cam follower roller 120 journalled thereto and riding in the cam track 106 in the bolt, and a longitudinally aft extending neck portion 122 terminating in a head portion 124. A rod 126 is threaded into and extends longitudinally forward fromthe block to a firing pin support 128, from which the firing pin 130 extends longituidnally forward. A main firing pin spring 132 is disposed on the rod 126, and a reflex spring 134 is disposed on the pin 130. The spring 134 is captured between the support 128 and a shoulder 136 in the bore 116. The spring 132 is captured between the support 128 and a shoulder 138 on the receiver. The bore 84 in the receiver has a centripetal projection 140 which extends longitudinally from shoulder 136A to 138A, and transversely for 90, to mate with a peripheral cut out 146 on the bolt which extends longitudinally from the shoulder 142 to the shoulder 148 transversely 360, and to the shoulder 104 transversely 135.
A trigger-sear assembly 150 is also disposed in the receiver. A trigger pivot shaft 152 is journalled in a transverse bore 154 through the receiver. A trigger 156 is fixed at 158 onto the shaft 152. A lower, bifurcated main sear 160, with an upwardly directed hook 162 is fixed at 164 onto the shaft 152. An upper, semiautomatic sear 166 with a downwardly directed hook 168 is disposed within the bifurcation and is journalled on a transverse shaft 170 which is fixed in a transverse bore 172. A torsion spring 174 is disposed on the shaft 152 and partially in a' blind counterbore in the sear with one end 176 captured by the receiver and the other end 178 captured in the tail of the sear 166. The spring biases the tail of the sear 166 upwardly, and via the shaft biases the hook 168 downwardly and the Y hook 162 upwardly. The aft searvsurface of the hook 162 is slightly forward of the aft sear surface of the hook 168. A safety has a handle 180 extending transversely from the aft end of a main arm 182 which is journalled on the shaft 152 and extends forwardly into a transverse interposer bar 184 which extends into an auxiliary arm 186 which is also journalled on the shaft 152. When the handle 180 is upQthe bar 184 is down and blocks forward movement of the firing pin actuator block 118. When the handle is down, the bar is up and clears the block.
A longitudinal-horizontal slot 188 is formed in the right side of receiver, through to the bore 84, to receive a charger blade .190 having a horizontally extending handle 192 and two vertical guide pins 194 and 196. The pins ride in a longitudinal-vertical slot 198 intersecting the slot 188. The slot 198 has an off-set portion at its forward end, which permits the handle to be swung out from the disposition shown in FIG. 10A to the disposition of FIG. 10B whereat the aft inner corner 144 of the blade projects into the bore 84 whereat it may engage the forward face of the cam follower support 32. Rearward movement of the swung out charger handle will drive the cam following support32 aft, compressing the main spring 108.
A vertical slot 200 is formed in the bottom of the receiver, through to the bore 84, to receive a magazine 202 of ammunition. The'magazine stores three vertical columns of rounds. The magazine has a left wall 204, a right wall 206, a front wall 208, an aft wall 210, a bottom 212, a left inner partition 214, a right inner partition, three followers 216 and three springs 218. The upper ends of the left and right walls are curved inwardly, and the upper ends of the left and right partitions are curved inwardly, to partially obturate the upper ends of the three columnar passageways, and thereby limit vertical movement and loss of rounds from the passageways. The left and right walls have respective shoulders 220 which abut respective projections 222 in the receiver to limit upward movement of the magazine into the slot. A bifurcated latch 224 is fixed on the aft wall 210 to engage a detent on the trigger guard 16, to releasably secure the magazine in the slot.
The receiver also includes three longitudinally extending, parallel, 90 angularly spaced apart, loading grooves 226, 228, and 230; three longitudinally extending, parallel, 90 angularly spaced apart, extraction grooves 232, 234, and 236 alternating with the loading grooves at 45; and three longitudinally extending but diverging, 90 angularly spaced apart, ejection tunnels 238, 240, and 242. The receiver also includes a groove 244 adapted to receive a portion of the ball 96 disposed in the bore 92 in the bolt.
In operation, a loaded magazine of ammunition is thrust into the slot 200 and the latch 224 is locked to the guard 16. The charger is swung to-engage the actuating cam follower support 32, and is pulled aft to push the actuating rod 26 aft. The rod carries the bolt aft and compresses the main spring, as will be described in more detail below, until the face 104 of the bolt is aft of the magazine ammunition. The respective topmost round in each of the three columns are biased up within their respective passageways, and when the charger handle is released, the main spring drives the bolt forward, with the annular shoulder 104 abuting the bases of the three rounds and stripping them forward out of the magazine and into the respective loading grooves 226, 228, and 230. The rod and bolt continue forward, ramming the rounds, as shown in FIG. 5, into the chambers 56, 58, and 60. The actuator rod, the bolt, and the revolver rotate 90 clockwise to the battery-first round-start of burst disposition, shown in FIG. 1. As shown in FIG. 11, the actuating rod cam follower 42 is at disposition A and as shown in FIG. 12 the firing pin cam follower roller 120 is at disposition a. The trigger 156 is forward, the lower sear hook 162 is engaged with the firing pin actuator head, the upper sear hook 168 is above and clears the head, and the firing pin spring 132 is compressed.
When the trigger is pulled aft, the longer, lower, sear hook is disengaged from the firing pin actuator head 124. The shorter, upper hook is resiliently pulled down, but only abuts the head 124 and does not engage it, and the firing pin 130 is driven forward by the spring 132 to fire the round in the chamber 56, with roller 120 travelling to disposition b. After the fired bullet passes the actuating gas port 52, combustion gas enters the gas cylinder and drives the piston 24 and the rod 26 aft. The follower travels aft to disposition B, providing a dwell period for gas pressure to decline the chamber, and then travels through a 90 rotation to disposition C, rotating the revolver and the bolt 90 to align the chamber 58 with the gun barrel bore 83, and driving the roller 120 up the ramp to disposition c, and compressing the spring 132. The head 124, however, is not far enough a aft to be engaged by either hook. The trigger is still aft, the lower sear hook is still down, and the upper sear hook is still too short to engage behind the head 124. The roller 120 falls to disposition d, and the spring 132 drives the firing pin to tire the round in the chamber 58. Combustion gas agairis drives the piston and the rod aft. The follower 40 travels aft to disposition D, providing a dwell period for gas pressure to decline, and then travels through a 90 rotation to disposition E, rotating the revolver and the bolt 90", to align the chamber 60 with the gun barrel bore, and driving the roller 120 up the ramp to disposition e, and compressing the spring 132. The trigger is still aft, the lower sear hook is still down, and the upper sear hook is still too short to engage behind the head 124. The roller 120 falls to disposition f, and the spring 132 drives the firing pin to fire the round in the chamber 60. Combustion gas again drives the piston rod aft. The follower 40 travels aft to disposition F, providing a dwell period for gas pressure todecline, and then travels through a rotation to disposition G, rotating the revolver and the bolt 45 to align the chambers 56, 58, and 60 with the extraction grooves 232, 234, and 236. The roller 120 travels to disposition g. The ball 96 carried in the bore 92 in the bolt, and partially disposed in the concavity 244 in the receiver, is aligned with the concavity in the actuating rod and the key 46 in the rod is bottomed in the blind keyway 90 in the bolt. As the follower 40 travels aft to disposition H, the rod drives the bolt aft, shifting the ball 96 in the bolt from the concavity 244 in the receiver to the concavity 50 in the rod, thereby interlocking the bolt to the rod. Further, the extractor tips 98, 100, and 102 pull the respective cases partially out of the chambers 56, 58, and and partially into the extraction grooves 232, 234, and 236 in the receiver. The roller 120 travels to disposition h. The follower 40 continues to disposition I fully pulling the cases (misflred cartridges) into the extractor grooves and rotating 45 to align the chambers 56, 58, and 60, as seen in FIG. 5, with the loading tunnels 226, 228, and 230, as seen in FIG. 6, and the ejection tunnels 62, 64, and 66 with the extraction grooves 232, 234, and 236 and the ejection tunnels 238, 2410, and
242. The roller 120 travels to disposition i and is cammed fully aft so that either sear hook can engage the head 124. If the trigger is still aft, the shorter, upper hook 168 will engage. If the trigger is forward, the longer, lower hook 162 will engage. The firing pin spring 132 is compressed. The follower 40 continues aft to disposition .l, at which the annular shoulder 104 on the bolt is immediately 'aft 01' the magazine. The three topmost rounds in the magazine rise to the top of the magazine and are tilted forwardly-upwardly. The roller 120 is at disposition j. The piston 24 is aft of the gas vent 541 and much of the combustion gas vents to the atmosphere through the vent, reducing the gas pressure in the cylinder.
The spring 108 starts to expand, driving the actuating rod and the bolt forward, the annular shoulder 104 stripping the three rounds out of the magazine and into the grooves 226, 228, and 300. As the rounds enter the grooves, they tilt to the longitudinal and engage the extractor lips. When the follower 40 is at disposition K,
the rounds have been pushed into the loading grooves 226, 228, and 230. The roller 120 is at disposition k. When the follower 40 is at disposition L, the rounds have been fully chambered, the empty cases have been impelled forward by the annular shoulder of the bolt and ejected, and the ball 96 is aligned with and enters the groove 2441, releasing the bolt from the rod. As the follower 40 travels to disposition M, the roller 120 trav' els to disposition 1. The follower 40 finally travels to disposition A rotating the bolt and the revolver to align the chamber 56 with the gun bore, The roller rotates 90 to disposition a. The rifle is now at battery, and awaits another pull of the trigger to fire another burst of three rounds.
