Patent number: 7752795Abstract: New design for semi-automatic weapon for several tubes cartridges loading system for long guns, wherein an in-between connection steel part fixes the barrel to the receiver. The retention of the cartridges inside the parallel tubes is done by three metallic nails. The springs of the loading tubes push the cartridges into the cylinder inside the gun through three openings made into the front side of the receiver under the barrel. The rotation mechanism of the cylinder is a result of changing the movement of the bolt from horizontal into vertical.Type: GrantFiled: April 4, 2007Date of Patent: July 13, 2010Inventor: Juan Francisco Mautone Medvedeo

Patent number: 7194836Abstract: A gun attachment adapted to fit to the subframe of a handgun and mount to a laterally extending member which can be a modified laterally extending member to extend beyond the lateral surfaces of the subframe, whereby an extension member which moves with respect to a base member applies a force to the trigger guard of the subframe, thereby creating a positive torque counteracted by engagement of a chamber region to the forward portion of the subframe whereby the gun attachment is rigidly attached to the subframe of the handgun without substantially modifying the same. The handgun attachment further comprises a forward member adapted to have load exerted thereon and transferring the load to the subframe and not to the slide, thereby maintaining the handgun in battery and allowing the handgun to be fired in a close quarter situation.Type: GrantFiled: November 8, 2004Date of Patent: March 27, 2007Inventor: Brian Urban

Patent number: 7159584Abstract: The airgun firing mechanism of the present invention has a rotary magazine 1 with a plurality of bores 11 made from a material through which magnetic force can pass, and a magnet 10 is provided in the center of the magazine 1. Also, the airgun firing mechanism of the present invention has inner diameters of respective bores 11 of the rotary magazine 1 having a plurality of bores 11 formed to inner diameters capable of having pellets 91 inserted into them, with the magazine 1 being formed from a material that can pass magnetic force, and with a magnet 10 being provided in the center of the magazine 1. In this way, it is possible to repeatedly fire two different types of bullets, namely BB bullets 90 and pellets 91, using one magazine 1 of one airgun G.Type: GrantFiled: May 28, 2003Date of Patent: January 9, 2007Assignee: Maruzen Company LimitedInventors: Tetsuo Maeda, Yoshiyuki Maeda

Patent number: 7012169Abstract: A device that can be used to treat appendage ailments is provided. The device, or appendage sleeve, can be used for wounds, cuts, and blisters, as well as joint related ailments, such as arthritis and carpal tunnel syndrome. In some instances, the appendage sleeve can at least partially made from an elastomeric material, such as an elastomeric nonwoven, so that the sleeve can more aptly fit onto a finger or toe. Furthermore, the sleeve can also possess a barrier that is liquid impermeable, but vapor permeable so that the finger or toe of a user is more comfortable. Various additives can be applied to the sleeve to aid for therapeutic purposes.Type: GrantFiled: April 4, 2001Date of Patent: March 14, 2006Assignee: Kimberly-Clark Worldwide, Inc.Inventors: Jason P. McDevitt, Michael S. Brunner, Kaiyuan Yang, Jark Lau, John Metz

Patent number: 5924230Abstract: A firearm which exhibits the geometric inability to jam. Further, the nature of the described firearm insures increased safety, versatility of calibers, ease of loading, higher potential capacity, unique gas operations, and reduced perceived recoil, over designs presently employed in the art of firearms manufacture.Type: GrantFiled: March 16, 1998Date of Patent: July 20, 1999Inventor: Clare L. Hoke, Jr.

Patent number: 5727345Abstract: A semiautomatic firearm having a rotating cylinder is provided. The cylinder has a plurality of chambers adapted to receive a cartridge and is rotatingly supported in a housing by a cylinder pin whereby each of the chambers of the cylinder is positionable in one of a loading position, a firing position, and an ejecting position. The cylinder pin is reciprocally movable between a retracted position wherein the cylinder pin is disengaged from a firing mechanism and an extended position wherein the cylinder pin engages the firing mechanism so as to cock the firing mechanism. The cylinder pin is movable from the retracted position to the extended position in response to gas pressure generated by the firing of a cartridge disposed in the chamber of the cylinder positioned in the firing position acting on the cylinder pin so as to move the cylinder pin from the retracted position to the extended position.Type: GrantFiled: June 17, 1996Date of Patent: March 17, 1998Assignee: Hotshot, Inc.Inventor: Robert Sullivan

Patent number: 5669171Abstract: This speedloader, which is usable to facilitate the loading of bullets into the magazine of an automatic rifle, comprises a casing that has a passage extending therethrough from its top to its bottom, the passage having an open top through which bullets may be fed and an open bottom into which the top of the magazine may be inserted. The speedloader also comprises means for fastening the magazine to the casing in a position within the passage that allows bullets to be fed through the top of the passage into the magazine. Atop the casing is an adapter for releasably attaching to the casing a stripper clip holding bullets. Means is provided for fastening the casing to the belt of a rifle-user so that the casing remains fixed to the belt, and hence to the waist of the rifle-user, as bullets are pushed downwardly off the stripper clip into the magazine.Type: GrantFiled: September 17, 1996Date of Patent: September 23, 1997Inventor: Thomas A. Sally

Patent number: 5651204Abstract: The present invention relates to an ornamental base attached to an ammunition magazine for magazine fed weapons, particularly handguns. The ornamental base is attached to a conventional magazine. A locking means comprising a hook shaped tab and aperture is used to keep the ornamental base securely attached to the magazine. The locking means is accessible through an elongated channel extending from the back edge of the base plate to the aperture. This type of locking means allows the entire outside surface of the base plate to be utilized for decoration as desired.Type: GrantFiled: August 3, 1995Date of Patent: July 29, 1997Inventors: David A. Hulsey, Don B. Lopez

Patent number: 5615505Abstract: An improved magazine for a semi-automatic pistol adapted to be loaded with a plurality of horizontally oriented and vertically stacked cartridges or bullets. A follower on the upper end of a coil spring supports the stack of rounds which are fitted individually into the top opening of the magazine with the first being disposed on the follower and subsequent rounds being supported by the body of the previous round. The last loaded, or uppermost round, when the magazine is fitted into the gun, will be the first round to be loaded into the chamber of the gun for firing. At the upper sidewalls thereof, the magazine includes lips which, at upper edges, are spaced apart a distance less than the diameter of the cartridges to be used in the pistol. A ridge disposed in each of the side walls of said magazine parallel to the upper edges of said lips, the ridges are spaced apart a distance less than the diameter of the cartridges which are held thereby.Type: GrantFiled: July 20, 1995Date of Patent: April 1, 1997Assignee: Smith & Wesson Corp.Inventor: Pardip K. Vaid

Patent number: 5369007Abstract: A microassay card includes an upper layer containing wells for receiving a liquid sample. A second layer of the card, beneath the first layer, includes a supporting surface bound to a reactive species. A third layer includes a superabsorbent support impregnated with an indicator. Typically, the indicator is a substrate for an enzyme, such as a reduced dye precursor and a source of hydrogen peroxide necessary for the action of the enzyme upon the substrate to cause a spectral change in the absorbent layer. By selecting the structure of the first and second layers, the card can be formatted for a displacement assay or a competitive assay. The microassay card of the present invention is particularly useful for drug testing.Type: GrantFiled: August 26, 1992Date of Patent: November 29, 1994Assignee: The United States of America as represented by the Secretary of the NavyInventor: David A. Kidwell
