Dual profile pen gun

Abstract

The Dual Profile Pen Gun is a highly concealable, hand held firearm of novel design, commonly referred to as a pen gun, having the appearance and esthetics of a pen like instrument when in a neutral, non firing mode, and can only be fired by manipulating the gun out of its straight axial pen like position into an approximate (90 degree) right angle bend, so the handle of the gun is below and at an angle to the bore of the gun. In this position the weapon is in the ready to fire position and can be held safely in the palm of the hand, until either fired or put back into a straight neutral position. To fire, a safety ring must be twisted clockwise, aligning the breechblock aperture with the firing pin. After the gun has been fired, the firing pin must be retracted back behind the breechblock wall and the safety ring turned counter clockwise allowing a tab on the rearward end of the barrel sufficient clearance so the barrel can be removed for reloading or replaced by an adapter threaded to receive a replacement barrel of any diameter, of any length, allowing this single weapon to potentially fire any caliber pistol, rifle or shotgun ammunition.

Having thus described the invention, I claim as new and desire to secure by Letters Patent:  
     
         1 . A pistol which simulates the appearance of a modern pen like instrument, comprised of a barrel adapted to receive a cartridge and threadably connected to a main body having coaxial front and rear bores spaced apart by a breechblock with an aperture whose reciprocating movements are controlled by a safety ring which when twisted aligns the breechblock aperture with the firing pin assembly mounted for reciprocative movement in the main body to project a firing pin through said aperture and engage and fire said cartridge after pulling the barrel forward and the rear housing rearward exposing a hinge joint that will allow said rear housing to be bent below and at an angle to said barrel exposing a hidden trigger and causing said firing pin assembly to be drawn rearward until it is released by pressing said trigger inward causing a control pin to release a cam which in turn releases said firing pin assembly under pressure from a compressed spring to force the firing pin forward with sufficient kinetic energy to fire said cartridge.  
     
     
         2 . The invention of  claim 1 , wherein a pistol simulating the appearance of a modern pen like instrument cannot be fired when in the neutral, (180 degree) straight-line pen like axial configuration.  
     
     
         3 . The invention of  claim 2 , wherein a pistol simulating the appearance of a modern pen like instrument cannot be fired until the firearm is manipulated out of its straight line axial configuration and bent at an angle with the guns rear housing (handle) at an angle to and below the bore of the barrel.  
     
     
         4 . The invention of  claim 1 , wherein a pistol is fitted with a reciprocating breechblock with an aperture formed within, whereby its movements are controlled by an external safety ring which when twisted clockwise slides the breechblock in a position so that said breechblock aperture is aligned with the firing pin.  
     
     
         5 . The invention of  claim 4 , wherein a pistol is fitted with a reciprocating breechblock controlled by an external safety ring which when twisted clockwise aligns the breechblock aperture with the firing pin, and when fired said firing pin is protruding through the breechblock aperture, whereby a tab on the rearward end of the barrel interferes with the rotation of the barrel, thereby not allowing the removal of the barrel for reloading.  
     
     
         6 . The invention of  claim 4 , whereby a pistol is fitted with a reciprocating breechblock controlled by an external safety ring which when twisted clockwise aligns the breechblock aperture with the firing pin, and when fired said firing pin is protruding through the breechblock aperture, whereby a tab on the rearward end of the barrel interferes with the rotation of the barrel until the firearm is manipulated back to a straight position, manipulated back into a bend to fire position, which retracts the firing pin rearward and out of breechblock aperture, which allows the safety ring to be twisted counter clockwise, repositioning the breechblock aperture to block the forward motion and thus allow the tab to clear the breechblock and allow the rotation and removal of the barrel.  
     
     
         7 . The invention of  claim 1 , whereby a pistol which simulates the appearance of a modern pen like instrument, comprised of a barrel which can be replaced with an adapter formed at one end to accept an alternative barrel and threadably connect rearward to the main body with an internal passage channel formed within to house a secondary firing pin, whereby said replacement barrels can be formed to fit any and all standard ammunition calibers in any length.  
     
     
         8 . The invention, whereby a pen gun type weapon uses the bend to fire concept to seek federal re-classification from a Title II, National Firearms Act classification to that of a Title I firearm.  
     
     
         9 . The invention of  claim 8 , whereby a pen gun type weapon must be manipulated from a straight axial position to a position where the handle of the pen gun is below and at an angle to the bore of the pen gun there by allowing possible re-classification from a Title II NFA classified weapon to that of a Title I firearm.  
     
     
         10 . The invention, whereby modifications can be made to the main body (receiver) and barrel sections of the firearm that will allow an external ammunition storage devise to hold and fire multiple cartridges thus becoming semiautomatic.  
     
     
         11 . The invention, whereby a pen gun type weapon uses the bend to fire concept to seek federal re-classification from a Title II, NFA classification to a Title designation whereby modifications are made to the receiver and barrel that will allow use of an external ammunition devise to hold and fire multiple cartridges of ammunition and thus be considered semiautomatic.
