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.

Description

[0001] In 1968, the United States Congress enacted the Gun Control Act of 1968 commonly referred to as the National Firearms Act. A section of this new law designated Title I, covered firearms that could legally traded without federal interference. A second section was designated Title II, and covered military style and unconventional firearms, like pen guns, machine guns, sawed off shotguns and cane guns. These newly classified firearms immediately became unlawful to own, sell or manufacture without going through a transfer process and paying a special tax that registered each weapon and owner with the National Firearms Registration and Transfer Record. The pen gun was for all potential purposes now unlawful to own, manufacture or sell without going through this cumbersome transfer process. The National Firearms Act ensured that pen guns were for now economically unviable as a marketable product. The Dual Profile Pen Gun "bend to fire" design over came the NFA regulations regarding...

Problems solved by technology

The size of the aperture of the central member dictates the maximum diameter size of the barrel, which limits the size and caliber selection of the ammunition, which can be chambered into the barrel.
