Definitions
- This invention is a device to make firearms, particularly handguns, more particularly revolvers and semiautomatic (sometimes called automatic) pistols, inoperative.
- the invention is directed to all forms of firearms, for purposes of further disclosure the use of the word "handguns” will be used to describe the invention, though it is to be expressly understood that the disclosure is in no way limited by use of the word "handguns,” as having applicability to all firearms containing a barrel and a chamber to accept metallic cartridges.
- both the barrel and chamber of a handgun are rendered inoperative, thereby preventing the insertion of a cartridge or "round” into the chamber while simultaneously blocking the barrel of the handgun.
- a trigger lock will not guarantee discharge of a loaded firearm and it is possible to insert a round into the chamber or cylinder of a handgun while a trigger lock is still on the gun. It is also possible in some instances to discharge the firearm by accidently or purposefully forcing the hammer to strike the round or, alternatively, to strike the trigger lock and/or hammer so as to release the trigger/hammer and discharge the round.
- the present device is designed to overcome such deficiencies of the trigger locks insofar as the device of the invention makes it impossible to chamber a round. As it is impossible to insert ammunition into the chamber of the handgun, it is impossible to fire the handgun.
- the invention consists of telescoping components, preferably an inner and outer sleeve, which are slidable relative to one another and which are usually inserted from the muzzle end of the handgun so as to travel from the muzzle through the barrel and the chamber of the handgun.
- At least one of the telescoping parts has a configuration, at an end remote from the muzzle so as to expand a distal end of that part into locking relationship with the chamber of the handgun.
- the invention also includes a locking cartridge which is manufactured such that its outside configuration conforms to the dimensions of a round which is normally fired from such gun.
- the locking cartridge fits precisely into the chamber of the gun and, as in the former embodiment, the end of at least one of the telescoping components distal from the muzzle end of the handgun is designed to grab the locking cartridge and lock it into the chamber of the gun.
- a locking device is provided, which may be key, combination or electronically activated to prevent movement of the grabber and, thus, retain the handgun in a locked and safe position.
- Fig. 1 is a schematic drawing of a prior art semiautomatic pistol based on a Browning design, and adopted by Colt and other manufacturers in .45 ACP, and other calibers, illustrating an empty chamber and barrel;
- Fig. 2 is a drawing of the same semiautomatic pistol of Fig. 1 with the locking cartridge placed in the chamber and the telescoping components, which are inserted from the muzzle end of the pistol, interlocking with the locking cartridge; a lock is shown schematically to fix the telescoping components in their as locked condition with the locking cartridge;

- the chamber and barrel may be a single component, for example, in many semiautomatic (sometimes also called automatic) pistols.
- the chamber is distinct from the barrel, for example, in the case of revolvers.
- Some pistols also borrow technology from long guns, i.e. the use of a bolt in a pistol configuration is well established.
- the metallic cartridges for these various firearms come with heads which are rimmed, semi-rimmed, rimless, rebated, belted, etc.
- the locking device of the invention can be made to interact with any firearm chambered for any of these types of metallic cartridges.
- the invention is not limited to locking devices for pistols, but may be used in long arms as well, for example rifles or smooth bore long arms, e.g. shotguns, rifles for shot shells, etc. It is, thus, intended that the invention can be used for any modern or antique firearm which employs a chamber for a metallic cartridge, as well as a barrel through which a discharged projectile travels from the chamber to the muzzle of the firearm.
- the term "handgun” will be used generically for all firearms so configured.
- One component which is essential to the invention are telescoping members such that at least one of the telescoping components will have an end thereof distal from the muzzle of the handgun which can be enlarged or expanded so as to interlock directly with the chamber or the end of the chamber or, alternatively, to interlock with a component placed within the chamber so as to render it impossible to chamber a round into the handgun.
- the telescoping members are cylindrical, although other configurations can obviously be employed without departing from the scope of the invention. For example, a rectangular or triangular configuration of the innermost telescoping member will work equally well as would a cylindrical configuration.
- a second component i.e. a locking cartridge 12 generally having the outer configuration closely conforming to the chamber will be inserted into the chamber and at least a grabber member 14 inserted into the locking cartridge where it is expanded so as to interengage with the locking cartridge so as to prevent axial (or longitudinal) separation thereof.
- a locking device 18 which will prevent axial (or longitudinal) movement of the telescoping members.
- a locking cartridge as it is possible to configure the grabber member so as to directly interengage the flanges 40, 41 (Fig. 11) with the end of the cylinder containing the chamber or, alternatively, to interengage with an undercut portion in the cylinder, i.e. that portion of the cylinder recessed to accept a rimmed, semi-rimmed or belted cartridge or, alternatively, on that portion of the chamber upon which the cartridge headspaces.
- the flanges may engage with the end of the chamber on which the .45 ACP cartridge seats.
- Such a configuration will not only prevent a round from being chambered, but will simultaneously prevent the cylinder from being rotated and, as in the case of the pistol, will make it impossible to discharge a projectile through the barrel of the firearm without authorized delocking of the locking device 18.
- a straight wall or a bottleneck cartridge is used in a pistol (e.g. a cartridge known as a 22 Remington Jet)
- a locking cartridge 12 in the revolver into which the grabber member 14 may be locked thereby preventing rotation of the cylinder, completely rendering useless any attempt to insert a round into the chamber and preventing discharge of a projectile through the muzzle of the revolver.
- the hammer 2 of the pistol or revolver is forced, it will not be possible to strike any cartridge within the chamber of the handgun.
- the components used in my invention can be made of any high quality metal, such as gun steel, and finished in blue, nickel or other finishes conventionally used to finish firearms.
- a metal such as stainless steel, which provides both aesthetic and functional features consistent with the purpose of preventing unauthorized discharge of a firearm equipped with the gun lock components of the invention, could be used.
- the components of the locking device of the invention may take the appearance as shown in Figs. 14 and 15 (shown without the firearm on which they will be installed).
- the grabber 14 will have its prongs (preferably at least 2, but three or more prongs being preferred) expanded by movement of innermost telescoping member 15 relative to grabber component 14 to expand the prongs 40, 41 (Fig. 11) into engagement with locking cartridge 12.
- the prongs 40, 41 will prevent longitudinal (axial) separation of locking cartridge 12 and grabber component 14.
- Locking cartridge 12 can be securely maintained in the chamber of the firearm by engaging the components of the lock 18 with one or more grooves 19, 21 (Figs. 3, 7) with locking component 23 of lock 18.
- Lock 18 can be a keyed, combination or electronic lock to move pin 23 into position with one of the grooves 19, 21 on grabber component 14. Once locked, the locking cartridge 12 will be secured in the chamber of the firearm, and its physical presence will prevent the insertion of a round into the chamber. Components 14, 15, 16 will be surrounded by the barrel of the firearm, thereby preventing tampering with these components as a means for unauthorized delocking of the device of the invention.
- Lock 18 may fit flush against the muzzle 9 of the firearm, or may be recessed as at 8 (Fig. 3) such that it relatively telescopes over muzzle 9 thereby further minimizing separation of the locking device of the invention from the firearm so equipped by preventing prying of the lock 18 from muzzle 9, by insertion of a prying tool (not shown) between the lock 18 and muzzle 9.
- the lock 18, and telescoping components 14-16 can readily be removed from the barrel and locking cartridge 12 ejected from the chamber by the means used to conventionally eject spent and/or unfired rounds from the chamber of the firearm.
