Abstract
A fire arm includes a body and a handle carried thereby as well as first and second barrels secured to the body. The second barrel is secured below the first barrel. A first loading mechanism is located in the body for loading the first barrel and a second loading mechanism is loacted in the body for loading the second barrel. A first magazine is selectively secured to the body for supplying the first loading mechanism and a second magazine is selectively secured to the body for supplying the second loading mechanism. The second magazine is spaced from the first magazine. A firing mechanism, which is located in the body allows a sequential firing of the first and second barrels.

BACKGROUND OF THE INVENTION

This application is a continuation-in-part of application Ser. No. 310,700 filed on Feb. 14, 1989, now abandoned. This invention relates to firearms. More specifically, the present invention relates to a double barreled firearm which is selectively automatically repeating and in which single barreled operation can be chosen if desired. The invention will be specifically described in relation to a submachine gun utilizing upper and lower barrels fed by two separate magazines which are spaced from each other. It should be recognized, however, that various aspects of the invention could also be utilized in other types of firearms such as pistols, rifles, shot guns, and the like. While there have been many automatic firearms of various sorts, each has had its disadvantages. Attempts have been made heretofore to design automatic firearms having parallel barrel systems which are coupled together in such a manner that they will fire alternately. Attempts have also been made to allow either a single barreled or double barreled operation of such weapons. However, the need still remains for a double barreled machine gun which has a wide range of firing characteristics but is simple to operate, can be braced against the user and has sighting capabilities. Accordingly, it has been considered desirable to develop a new and improved firearm construction which would overcome the foregoing difficulties and others and meet the above-stated needs while providing better and more advantageous overall results. In accordance with the present invention, a new and improved firearm is provided. More particularly, in accordance with this aspect of the invention, the firearm comprises a body and a handle carried thereby as well as first and second barrels secured to the body. The second barrel is secured below the first barrel. A first loading mechanism is located in the body for loading the first barrel and a second loading mechanism is located in the body for loading the second barrel. A first magazine is selectively secured to the body for supplying the first loading mechanism and a second magazine is selectively secured to the body for supplying the second loading mechanism. The second magazine is spaced from the first magazine. A firing mechanism, which is located in the body allows a sequential firing of the first and second barrels. According to another aspect of the invention, a machine gun is provided. According to this aspect of the invention, the machine gun comprises a body including a handle at one end and first and second barrels secured to the body. First and second firing mechanisms are located in the body in operative connection with the first and second barrels respectively. First and second magazines are selectively secured to the body for supplying ammunition to the first and second firing mechanisms respectively. A first control mechanism is located in the body for adapting the machine gun for selective automatic and semi-automatic operation. A second control mechanism is located in the body for adapting the machine gun for selective firing from both of the first and second barrels and from one of the first and second barrels. One advantage of the present invention is the provision of a new and improved firearm. Another advantage of the present invention is the provision of a submachine gun which has upper and lower barrels fed by separate magazines which are spaced from each other to give the gun better balance. Still another advantage of the present invention is the provision of a two barreled firearm with a control mechanism which allows either both barrels to be fired or one barrel to be fired individually, as desired. Yet another advantage of the present invention is the provision of a firearm in which a selector mechanism allows the firearm to be prevented from operation as well as to operate in a semi-automatic mode, and in an automatic mode. A further advantage of the present invention is the provision of a firearm which has front and rear sights, each of which is adjustable and in which the rear sight can be set for different distances. The rear sight is also provided with a central aperture and a plurality of surrounding side apertures to allow for greater visibility by the user. A still further advantage of the present invention is the provision of a firearm which has a folding stock that can be locked in either a stowed position or a use position. A yet further advantage of the present invention is the provision of a multiple barreled firearm with a recoil compensating muzzle secured to the free end of each barrel. An additional advantage of the present invention is the provision of a submachine gun having a rear grip and a front grip and in which the front grip can be either perpendicular to the body of the gun or located at an angle to the body of the gun. In both of these constructions the front grip is in the same plane as rear grip. In yet another construction, the plane of the front grip is spaced at 90.degree. from the plane of the rear grip. Still other benefits and advantages of the present invention will become apparent to those skilled in the art upon a reading and understanding of the following detailed specification.
