[ 5 7] ABSTRACT In cooperation with a caseless round of telescopic configuration, a longitudinally reciprocating plunger responsive to forward travel thereof moves the round projectile forwardly in the body member for insertion into the barrel bore for discharge. The plunger carries a firing pin which is spring-biased to a forward round impacting position and is driven rearwardly responsive to discharge gas pressure. A latch pivotally carried by the plunger is pivoted by the striker portion of the firing pin into engagement with a flange formed on the rear end of the projectile when the firing pin goes into its forward position and is held in engagement with the flange if the round fails to discharge thereby maintaining connection between the projectile and the plunger for withdrawal of the projectile back into the body member during rearward travel of the plunger.
5 Claims, 4 Drawing Figures RAMMER AND EXTRACTOR ASSEMBLY FOR TELESCOPIC ROUNDS BACKGROUND OF THE INVENTION This invention relates to gun structure for ramming the projectile in a round of telescopic configuration forwardly from the body member thereof and pertains more particularly to such a rammer adapted for use with caseless rounds whereby the projectile is withdrawn back into the body member if the round should fail to fire.
Ammunition rounds of telescopic configuration are generally found advantageous when space for feeding or chambering the rounds is critical because thereby the rounds can be fed and chambered at their minimum length and then extended after being chambered to locate the projectile forward of the propellant. Such configuration has been found advantageous, too, with caseless rounds as it eliminates the requirement for the bodymember, formed from solid propellant material, to provide axial support for the projectile. A problem, however, arises as to the removal of a dud round, which is, of course, in its extended configuration because the gun structure for chambering the round is adapted to accommodate it in its minimum, telescopic length.
SUMMARY OF THE INVENTION It is a principal object of this invention to modify the projectile in a caseless round of telescopic configuration and the longitudinally reciprocating gun rammer for pushing the projectile forwardly in the body member so that if the round should not fire the projectile is withdrawn back into the body member by the rammer during the rearward stroke thereof.
To achieve this object the rammer plunger, which carries the reciprocating firing pin which is springbiased in its forward round impacting position and is driven rearwardly responsive to discharge gas pressure is provided with a pivotal latch which is pivotally displaced by the conical striker portion of the firing pin into engagement with an annular flange, formed in the rear end of the projectile, when the firing pin goes into its forward position. The latch is held in engagement with the flange until the firing pin is actuated rearwardly by discharge gas pressure. If the round should fail to fire, the projectile remains connected to the plunger during its rearward stroke so as to be withdrawn thereby into the body member.
Further objects and advantages of the invention will be apparent from the following specification and the accompanying drawing which is for the purpose of illustration only.
BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a fragmentary, longitudinally cross-sectioned view of a firearm showing the structure of this invention with the projectile extended by the plunger and the latch in engagement with the annular flange in the base of the projectile;
FIG. 2 is a view similar to FIG. 1 but shows the projectile withdrawn back into the body member and the latch disconnected therefrom;
FIG. 3 is a cross-sectional view taken along line 3-3 of FIG. 1; and
FIG. 4 is an enlarged cross-sectional view showing the cooperation of the latch with the annular flange in the projectile when in engagement therewith.
DESCRIPTION OF THE PREFERRED EMBODIMENT Shown in the drawing is a firearm breech 12 provided therein with a split type chamber 14 which opens and closes responsive to cyclic actuation of the firearm operating mechanism (not shown) to receive a caseless round 16 for discharge. Round 16 is of a telescopic configuration and includes a projectile 18 initially located within an axial bore 20 through a body member 22 formed of a solid propellant material. A barrel 24 with a bore 26 is fixed to the front end of breech 12 in coaxial relationship with chamber 14 and the rear end of the bore is countersunk at 28.
Extending axially from chamber 14 through the rear end of breech 12 is a cylindrical hole 30 which mounts a plunger 32 for sliding reciprocation therein in forward and rearward strokes responsive to cyclic actuation of the operating mechanism. Plunger 32 has approximately the same diameter as bore 20 in round 16 so that such plunger is insertable thereinto during its forward stroke to push projectile l8 forwardly in body member 22 for extension into bore 26, as shown in FIG. 1. The forward displacement of projectile 18 is limited by contact of rotating band 34 thereon with countersunk portion 28. The front edge of rotating band 34 is beveled at 36 to conform with countersunk portion 28 thereby, when plunger 32 moves projectile 18 forwardly, the beveled edge of the rotating band is pressed against the counterbore portion to seal the front end of chamber 14.
Formed in the rear end of projectile 18 is a cylindrical recess 38 which is undercut to form an annular flange 40 around the mouth thereof, and located axially in the front end of the recess is a primer 42 which, when detonated, ignites body member 22. Primer 42 is detonated by a firing pin 44 which is terminated at the front end by a conical striker portion 48 and which is mounted in plunger 32 by means of an axial hole 46 therein for displacement between a retracted position and a forward position in impact against primer 42. F iring pin 44 is biased forwardly by spring 47 and is displaced rearwardly responsive to the gas pressure generated by ignition of body member 22. A radial slot 50 communicates with hole 46 and mounted in such slot is a latch 52 which is pivoted at the rear end for displacement between an outward engaging position and an inward disengaged position. The front end of latch 52 is terminated by a hook 54 which extends therefrom for engagement with flange 40 to lock projectile 18 to plunger 32 for displacement therewith when the latch is in the engaging position. Hook 54 is essentially of triangular configuration, as shown in FIG. 4, and includes a front inclined side 56 and a rear inclined side 58 both of which sides have camming cooperation with flange 40 as hereinafter described. Formed on the front end of latch 52, below hook 54, is a round protrusion 60 which, as shown in FIG. 1, is cammingly engaged by striker portion 48, when firing pin 44 moves into its forward position, to pivot latch 52 to its engaging position wherein hook 54 is located in front of flange 40 for transferring rearward movement of plunger 36 to projectile l8. Latch 52 is held in its engaging position by the blocking action of striker portion 48 through the forward bias of spring 47 against firing pin 44.
OPERATION When round 16 is located in chamber 14, the chamber is closed, and firing pin 44 is retracted, firing sequence commences by the forward displacement of plunger 32 which moves projectile l8 forwardly in body member 22 for insertion into bore 26 and which locates hook 54 forwardly of flange 40. Contact of front side 56 of hook 54 with flange 40 assures displacement of latch 52 to the disengaged position free of interference with the forward displacement of plunger 32. Round 16 is fired by release of firing pin 44, through trigger means (not shown), which is propelled forwardly by spring 47. As firing pin 44 moves to its forward position, striker portion 48 has camming contact with protrusion 60 thereby pivoting latch 52 outwardly to its engaging position with hook 54 located in front of flange 40, as shown in FIGS. 1 and 4. When striker portion 48 makes impact with primer 42 and body member 22 is ignited by the detonation, the resulting gases act against the striker portion to accelerate firing pin 44 rearwardly. During the initial retraction of firing pin 44, striker portion 48 moves away from protrusion 60 to free latch 52 for displacement to its disengaged position by movement of flange 40 against rear side 58 of-hook 54 as projectile 18 is propelled forwardly.
If body member 22 for any reason should fail to ignite, firing pin 44 remains in its forward position thereby maintaining striker portion 48 thereof in blocking relationship respective to latch 52. Thus, when plunger 32 is actuated rearwardly, responsive to the cyclic actuation of the operation mechanism (not shown), projectile 18 is drawn back into body member 22 and the dud round 16 is easily removed by suitable ejection means from chamber 14 when opened responsive to cylic actuation of the firearm operating mechanism (not shown).
I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described, for obvious modifications will occur to a person skilled in the art.
