PATENT PROJECTILE.

SPECIFICATION forming part of Letters Patent No. 734,966, dated July 28, 1903.

Application led January 17| 1903. Serial No. 139,475. (No model.)

To all whom it nury concern.-

Beit known that I, CECIL VILHELM ScHoU, a subject of the King of Denmark, residing at v Copenhagen,Denmark, have invented certain new and useful Improvements in Projectiles, of which the following is a full, clear, and exact description.

This invention relates to projectiles or bullets provided with material adapted to develop smoke or light, `or both, when they come in contact with the target or any other obstruction in their path.

The object of the invention is to .enable the gunner to determine the range, this being possible by reason of the fact that the smoke or flash created at theimpact of the projectile l"shows whether it falls short or overreaches thereto, preferably at its forward end, a fragmeans for protecting the capsule against frac-- ture from the shock of discharge, and Figs. 4

.and 5 illustrate further modifications.

The bullet or projectile itself may consist of the usual body a, of lead or other material, and may have the usual conical formation at the forward end.

b indicates a capsule which I may apply to the forward end of the bullet in any exposed manner, so that it will be shattered when the bullet strikes a reasonably hard object. This capsule may be made of thin sheet metal or glass and inserted into an orifice adapted to receive it in the' body of the bullet and with one end projecting to make contact with the object struck. The capsule contains a quantity of any substance adapted to become iniianied when exposed to the atmospheresuch, for instance, as zinc-ethyl, the combustion of which produces a flash of light and a dense smoke visible a long distance; The capsule may be held in place when necessary by -a sheath c of sheet metal, in which the projectile may be incased and which may have an openingat its forward end, through which the point of the capsule will project.

In the formation shown in Fig. 2 the special casingfor the capsule is omitted, the inflammable material being placed directly in a chamber e, formed partially by a cavity in the forward end of the projectile and partially by the sheath c, which covers the cavity and is of su iciently fragile construction to give way when the projectile strikes and expose the inflammable material to the atmosphere. Such a chamber for the indammable material is preferably filled by means of a passage e', leading rearward through a projectile, which after the iilling operation is closed by a suitable plug e2.

Fig. 3 shows a method of sustaining a capsule when it is made of specially fragile material, such as glass, which needs protection against the shock imparted to it when discharged from the gun. In this instance the cavity in the bullet which receives the capsule is lined with a soft cushioning material f, such as soft rubber or a mixture ot' glycerin and glue.

Fig. 4 illustrates a means for exposing the inflammable material when the projectile strikes without necessarily fracturing the container. This consists in making the container or capsule in the form of a cup g, which is inverted and fixed tightly over the forward end of the projectile, the latter havingaslight depression, if desired, which is inclosed by the cup and in which is placed a fulminate cap g'. The cup g carries a needle or firingpin g2, which is driven against the fulminate when the projectile strikes, causing a slight IOO explosion, which drives off the cup, exposes f the contents to the atmosphere, and fires the same.

Fig. 5 shows a.construction which diers 5 slightly .from Fig. 4 in that the inverted cup 'contains a fragile sealed glass tube h, con'- taining the liquid zinc-ethyl. The fracture i of this tube exposes its contents to the atmosfphere and, becoming inamed, sets fire to o the surrounding material, which, though not o at the impact.

When any of these types of projectile are fired from a gun, the smoke developed at the impact will clearly show to the gunner where the projectile strikes and he can adj ust the sights of the gun accordingly. If the firing is done at night, the Hash which also occurs at the impact gives the same information.

Having described my invention, I claim- 1. A projectile or bullet for firearms in coma bination with a fragile capsule containing a smoke-developing material and carried in or upon the projectile or bullet.

2. A projectile or bullet frrearms in composed to the atmosphere, said capsule being` located in said chamber and exposed at the forward end of the projectile.

4. A projectile or bullet having at its forward end a chamber or cavity lined with a cushioning material, in combination with a. capsule of fragile material located in said chamber and containing material capable of developing smoke -when exposed to the atmosphere.

5. The combination with a projectile or bullet provided with a chamber containing material adapted'to generate a smoke when exposed to the atmosphere and means for exposing said material at the impact of the projectile.

In witness whereof I subscribe my signature in presence of two witnesses.
