Disk-shaped bullet, bullet case and firearm with rectangular barrel for disk-shaped bullet

#1. Field of the Invention

#This invention relates generally to firearms and guns such as rifles and to the bullets propelled therefrom, and in particular relates to a firearm having a rectangular barrel for shooting a disk-shaped bullet and to a disk-shaped bullet and cartridge for use with the firearm.

#2. Description of the Related Art

#FIG. 1 is a perspective view of a first embodiment of the disk-shaped bullet of the invention.

#FIG. 2 is an elevational view of a side the disk-shaped bullet of FIG. 1.

#FIG. 3 is an elevational view of an edge of the disk-shaped bullet of FIG. 1.

#The present invention comprises a firearm with a barrel having a rectangular internal bore with teeth extending along one short side of the rectangular internal bore, a disk-shaped bullet (or “penny bullet”) and a bullet case as described and shown herein.

#The firearm with which the invention is used comprises a receiver and a stock as known in the art (not shown) and an elongated barrel 10. The elongated barrel 10 of the invention has an internal bore 12 having a rectangular cross-section 14 as shown in FIG. 18 to accommodate the disk-shaped bullet 16 (discussed below). In an example of a preferred embodiment of the invention components herein, the internal bore 12 is ½ inch× 3/16 inch as is the rectangular orifice 44 of the bullet case 42 (see below), and the disk-shaped bullet 16 is about 0.001 inch larger in each dimension than is the internal bore 12. The disk-shaped bullet 16 touches the internal bore 12 on all sides of the disk-shaped bullet 16 as is the case for prior art bullets and barrels. The disk-shaped bullet 16 compresses as it goes over the teeth 22, and as shown in FIG. 19, has an edge similar to a saw blade after progressing down the elongated barrel 10.

#The barrel 10 may be mounted on a receiver of a rifle as known in the art, in a vertical configuration (FIGS. 16-18). Alternatively, the barrel 10 may be shifted 90° to a horizontal configuration (FIG. 16 shows what the top of a vertical configuration would look like and FIG. 17 shows what a side of a vertical configuration would look like) or a diagonal position (not shown). Preferably the outside of the barrel 10 is rectangular. Multiple elongated barrels, each having a rectangular internal bore, may be mounted together, for example, stacked aligned side-by-side or stacked, to create multi-barrel, single-shot, multi-projectile configurations and are included in the invention herein.
