P D W, muzzle loaded less lethal personal defensive weapon

Abstract

This concept of a less lethal firearm is a new idea in an old adage. The weapon is designed to be discharged with either left or right hand. It expels non-metallic ball projectile(s) 20. It discharges only blank power load cartridges 22, where the cartridge gas chamber 04 is bored only to fit this casing. These blank power load cartridges 22 are of low caliber and rim fired. The weapon has a simplified firing mechanism FIG. 5, allowing all legal aged persons to discharge the weapon regardless of gender or physical disabilities. It is designed in a club/striking defensive characterized shape FIG. 9. The weapon is Small enough in design to be easily concealed on one's person (as per laws). The weapon can be constructed from all polymer, therefore making it light-weight. The bore 03 is not of a standard caliber. The projectile weight is extremely less than that Of standard leaded projectiles. Making the kinetic energy, in foot pounds, much less than that of leaded projectiles. A physiological effect is produced in the suspected targets mine, by the feeling of being struck by a projectile and not knowing if the projectile was a lethal bullet or not. (“Fear of the Unknown”)

1 . An elongated, cylindrical less lethal muzzle loaded personal defensive firearm type weapon that discharges a single to multiple plastic or rubber ball projectile(s), and any other less lethal projectile with the same caliber by means of a single rim fired blank power load cartridge. Having, a threaded smooth bore barrel assembly, a cartridge/gas chamber, a trigger plunger, a firing pin, a trigger plunger spring, a firing pin spring, safety pin a trigger plunger spring cap, a firing pin spring cap, firing pin guide and spring chamber, trigger plunger chamber, trigger plunger firing pin guide hole, firing pin milled shoulder, firing pin nail type head, safety pin hole and rubber o-ring, a threaded rear receiver, as outlined and set forth in the specifications and drawings.  
   
   
       2 . To claim # 1 , the barrel assembly is 4.0″ in length and 1.25″ in diameter. It is of a solid, one piece construction. It has two tubular bores drilled through it. One is a smooth bore (bored to fit the caliber of the present projectile(s)). The other is the cartridge/gas chamber (bored to fit only the presently selected blank power load cartridge casing) Both are bored on the center axis of the barrel. The cartridge/gas chamber at it's breach end has a seat cut out to fit the shoulder of the cartridge casing, so that the casing is flush with the end of the male mating threads. The male mating threads are to thread to the rear receiver. Behind the male mating threads there is an o-ring seal, which securely seals the two halves together. The lengths of both, the bore and cartridge/gas chamber have been selected to give the maximum effective range of 36 feet. The breach end is chaffered to fit to the rear receiver, to form a gas seal. As outlined and set forth in the specification and  FIG. 4 .  
   
   
       3 . To claim #  2 , the projectiles are plastic and/or rubber in the caliber of the present invention (9.35 mm) The weight is 8.2 grains plastic 10.2 grains rubber. [At present (with the presently selected blank casing) these weights obtain the kinetic energy of 16.2 ft./lb/plastic and 18.7 ft./lb/rubber.] As outlined and set forth in the specifications and  FIG. 1, 2 ,  3  and  4   
   
   
       4 . To  claim 2 , the propulsion system is derived in this way; being the bore of the weapon and the cartridge/gas chamber is bored on the center axis, the cartridge casing is then installed on center axis, the projectile is loaded on center axis. When the weapon is fired the gases from the explosion of the powder and primer of the casing rushes forward through the gas chamber striking the center axis of the projectile propelling the ball projectile to the target. As outlined and set forth in the specifications and  FIGS. 1, 2 ,  3  and  4   
   
   
       5 . To  claim 1 , the rear receiver is 4.25″ in length, and 1.25″ in diameter and is the operational part of the weapon. It is of a solid one piece construction, drilled only to house the firing mechanism. The female mating threads where cut on the center axis of the rear receiver. They are located at the front end of the rear receiver, at the bottom end of the threads, there is a chamferred end to meet with the chamferred end of male mating threads, to form a tight gas seal. At the front of the threads there is another chamfer, for in which the o-ring seal (behind the male mating threads) will seat, when the barrel assembly and rear receiver are threaded together. There is a firing pin guide hole drilled in the flat area below the female mating threads. The firing pin guide and spring chamber is drilled off center axis at 0.013 of an inch in order to fire the selected blank rim fired power load cartridge. The safety pin hole is drilled behind the trigger plunger chamber, both are bored perpendicular to the center axis. As outlined in the specifications and  FIG. 5 .  
   
   
       6 . To  claim 5 , the firing mechanism is constructed as follows; the trigger plunger spring cap is screwed into the rear receiver. The trigger plunger spring is inserted into the trigger plunger chamber, it bottoms out in the trigger plunger cap. The trigger plunger is then inserted, the trigger plunger springs upper most part fits into the recess cavity in the bottom of the trigger plunger. The firing pin is inserted into the firing pin guide and spring chamber. The trigger plunger is pushed downward, at this time the firing pin is slid through the trigger plungers' firing pin guide hole (which is elongated and drilled to the same diameter as the firing pin shaft) until it bottoms out. Then the firing pin spring is inserted into the recessed cavity in the firing pin nail type head. Finally the firing pin spring cap is screwed into in rear of the rear receiver. As outlined in the specifications and  FIG. 1, 2 ,  3 ,  5 ,  6 ,  7  and  8   
   
   
       7 . To  claim 6 , the trigger plunger is of a solid piece construction. Machine to fit only the trigger plunger chamber. There are no restriction or catches on it to hold it in place. The firing pin guide hole is drilled the same diameter as the firing pin shaft, and is elongated perpendicularly. This allows the firing pin to move freely through it. The (charging) latching action is derived by the upward force from the trigger plunger spring and this elongated guide hole, against the firing pin milled shoulder. The firing pin being through this elongated hole is what holds the trigger plunger in the weapon. As outlined in the specifications and  FIGS. 1, 2 ,  3 ,  5 ,  6 ,  7  and  8   
   
   
       8 . To  claim 6 , the firing pin is of a solid piece construction. It has two ends. The head which is machined smaller than the shaft and large enough for the firing pin guide holes and is semi-pointed. The rear end (nail type head) which is flat, and has a recessed cavity bored in it to fit the firing pin spring. The flat side of the nail type head is where the safety pin latches against if the weapon is accidental triggered. As outline in the specifications and  FIGS. 1, 2 ,  3 ,  5 ,  6 ,  7  and  8   
   
   
       9 . To  claim 1  &  5 , the safety pin is of a solid piece construction. It is bent at a 90 degree angle, ⅛ of an inch in diameter and ¾ of an inch long at the 90. It is placed in the safety pin hole after the rear receiver is armed (charged). It falls behind the firing pins' nail type head, to prevent accidental discharge. As outlined in the specifications and  FIGS. 5 & 6 .  
   
   
       10 . To  claim 2  &  5 , the loader rammer is of a solid piece construction. It has two ends. One is the large end, machined to fit the bores' caliber, and is the length needed to seat the present projectile(s). The other is the small end. Machined to the diameter of the firing pin guide hole. With it's end drilled to fit on the semi-pointed head of the-firing pin. It is of the length needed to push the firing pin all the way through the trigger plunger to the charged position. As outlined in the specifications and  FIG. 5 .  
   
   
       11 . To  claim 6  the tractable firing pin safety. Due to the firing pin's machined head, there is no firing pin orientation needed, thus any rearward force on the firing pin will cause the pin to partially retract into the trigger plunger. The firing pin must be totally retracted before it will charge (arm) and fire. As outlined in the specifications and  FIG. 8 .  
   
   
       12 . To  claim 2  &  5 , The weapon has two inherent safeties due to the present design. The ⅛ of an inch safety gap (firing pin no strike zone) and the total separation of the barrel assembly and rear receiver (which is understood by persons with skills in the art). The ⅛ inch gap just prevents the firing pin from string the cartridge casings' rim. As set forth in the specifications and  FIGS. 4,5  and  7 .  
   
   
       13 . To  claim 1 , the weapons elongated, cylindrical shape along with its' insert safety pin (if armed) tend to give it the ability to be a club/striking implement. Though this is not its' primary purpose. As set forth in the specifications and  FIGS. 1, 2 ,  3 ,  6 ,  7 ,  8  and  9 .  
   
   
       14 . To  claim 4  and  6 , the weapon at present design is capable of discharging three plastic or rubber projectiles simultaneously. The use of the three projectiles lends the weapon to be used functionally as a mini-shotgun. The projectiles separate in flight, penetrating targets to create a diamond shaped pattern, at the selected maximum effective range. The weapon still only uses A single blank power load cartridge, as set forth in the specifications and  FIG. 2 .
