Description

B. G. CHILDS BULLET Filed May 1, 1955 I nventm Ato'mey B. a. Chiid's Patented June 30, 1936 UNlTED STATES PATENT OFFICE 3 Claims.

This invention relates to a bullet, the general object of the invention being to provide a streamline bullet so formed as to reduce vacuum drag and air resistance which results in a flattened trajectory and increases accuracy in shooting.

Another object of the invention is to provide fins on the rear part of the bullet which conform to the spiral grooves in the gun or rifle and also to provide means whereby the exploding gases will act with full force upon the bullet throughout the length of the barrel.

This invention also consists in certain other features of construction and in the combination and arrangement of several parts, to be hereinafter fully described, illustrated in the accompanying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding parts throughout the several views, and in which:-

Figure 1 is a sectional view of a shell containing the bullet, the bullet being shown in elevation.

Figure 2 is a longitudinal sectional view through the bullet.

Figure 3 is a view looking toward the rear end of the bullet.

Figure 4 is a longitudinal sectional view through another form of the bullet.

Figure 5 is a view of the wadding.

As shown in these views the bullet A is formed of a substantially cylindrical intermediate part, a pointed front end and a pointed rear end, said rear end having the substantially spiral fins I thereon which conform to the spiral grooves in the gun barrel, the fins terminating an appreciable distance from the rear end of the bullet so that this rear end forms a pointed tail as shown. The rear ends of the fins form shoulders for receiving the front end of the wadding device shown generally at B in Figure 5. This device includes a casing 2 preferably of metal which encloses the disks 3 of any suitable material, the device having a tapered opening 4 therein for receiving the tail of the bullet. Asshown in Figure 1 the wadding device encloses the tail end of the bullet when placed in a shell C with the open end of the shell reduced to fit around the intermediate part of the bullet and the wadding, the bullet being provided with a groove 5 into which the end of the shell is crimped in the usual manner. Thus when the powder in the shell is ignited the resulting gases will act on the wadding and propel the bullet through the barrel of the gun, the wadding and the outer jacket entering the grooves in the barrel preventing the escape of the gases through the grooves so that the full force of these gases will act upon the bullet. As soon as the bullet leaves the barrel the wadding will drop therefrom.

Figure 2 shows the body of the bullet formed of any suitable material with a jacket of steel or the like, shown at 6 fitting over the rear part of the body, this jacket carrying the fins l and the tail and the body is grooved as at 1 and 8 for receiving parts of said jacket which are pressed into said grooves. Another jacket 9 fits over the front of the body and over the front part of the jacket 6 and the rear portion of the jacket 9 is grooved as shown at It] to press part of the jacket into the grooves of the jacket 5 where the said jacket is pressed into the groove 8 and this groove I receives the crimped end of the shell at 5.

Figure 4 shows the body I I formed of any suitable material shaped to provide the fins and tail with the pointed front end l2 of the bullet formed of lead which has a portion l3 entering a socket M formed in the body II. The jacket IS in this form of bullet terminates short of the pointed end of the part I2 and is pressed in the said part I2 as shown at It and the rear end of the jacket I is flanged as at I! and enters a groove in the body II. The fins shown at I are formed on the body I l and the tail I8 is also formed on the body and is provided with the projections l9 engaging the wadding to hold the wad on the tail until the bullet leaves the barrel.

As before stated this invention provides means whereby the full force of the gases will act ta project the bullet from the barrel without loss of gases and vacuum drag and resistance are reduced to minimum. As will be seen the fins serve two purposes, one to give a solid backing for the gases by way of the wadding that transmits the energy of the gases to the bullet through the fin ends, the other purpose being to impart a spinning motion to the bullet through its course of flight which results in more accurate shooting especially at long ranges.

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and arrangement of the several parts, provided that such changes fall within the scope of the appended claims.

What is claimed is:-

1. A bullet of the class described comprising a body part having a substantially cylindrical intermediate portion and pointed front and rear ends, a jacket enclosing the intermediate and rear parts of the bullet and having fins thereon of spiral formation, the rear ends of which are straight to form shoulders and terminate an appreciable distance from the rear end of the jacket, the intermediate part of the body having an annular groove therein, a jacket enclosing the front of the body overlapping the front portion of the first-mentioned jacket, said jacket having portions pressed into the grooves, the pressed portion of the second jacket forming a groove for receiving a portion of a shell.

2. A bullet of the class described comprising a body having spiral fins on its rear portion which terminate in straight ends located an appreciable distance from the rear end of the body, said rear end being pointed, a head forming portion attached to the body and being pointed and a jacket enclosing the intermediate portion of the body and a portion of the head forming portion, the front end of the jacket terminating short of the point of the head forming portion and being pressed into the same, the rear end of the jacket being flanged and extending into the body.

3. A bullet of the class described comprising a body part having 'a substantially cylindrical intermediate portion and pointed front and rear ends, and a jacket enclosing the intermediate and rearcparts of the bullet and having fins thereon of spiral formation, the rear ends of which are straight to form shoulders and terminate an appreciable distance from the rear end of the jacket.

BLISS G. CHILDS.
