To all wlwm it may cmtcem:

Be it known that I, GILBERT H. Hoxm, a citizenof the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Projectiles, of which the follow ing is a specification.

My invention relates to projectiles and 1s illustrated in the accompanying drawings vherein- -Figure 1 is'a longitudinal section through a projectile containing one form of my invention, Fig. 2 1s a similar view of a modification, Fig. 3 is a similar view of a still further modification, Fig. 4 is a side elevation of the device illustrated in Fig. '1, Fig. 5 is a longitudinal section through the device of Fig. 1 supposed to be taken at the moment hen the cutting edge has reached the target plate, Fig. 6 is a similar view at the moment when the impact part has struck, bulged and partly torn the disk out, of the plate to make a passageway for the' projectile. f

Like parts are indicated by the same latter in all the ures. l s

A is the ody of the projectile or ullet which may he projected 1n any!h sired manner and may be made of any desired material and may or may not be supplied with explosive material. B is a pocket for such explosive material illustrated in'Fig. 1. is one form, D another and E a third form of a filler for closin the forward chamber F in the bullet. This chamber is of any desired size, shape and depth but its presence results in forming an annular cutting ring or edge G at the forward end of the projectile. 'I he filler is preferably composed of a soft metal like lead which will melt un'der the heat of the impact er at least will not mate rially interfere with the further action of the bullet as hereinafter explained. t

J is the impact part, in this case shown in the form of a globe-like part, though it may be of any desired shape. It is supported within the chamber Fin an desired manner as, for example, by being s htly embedded in the Iillcr or filling plug or y being temporarily secured, as for example by lead or the like soft material, in the bottom of the cham- K is the plug to close the explosive material chamber.

L is the target plate. M the soft or other man suer 4in its distributed condition afar it has struck the target, N the disk which is being forced or punched out of the plate. Of course it will 'be understood that those par-ts are shown in a diagrammatic and illustrative manner without any attempt to get exact pro ortions or structures. 11st deed no exact raw ing illustrating the operation of the bullet upon impact can be had. I have illustrated this, however, for explanatory purposes, in connection with diagram of the-structure shown in Fig. 1. I think in the form shown in these drawings it is better that the chamber should be of eater cross sectional area than the movable lmpact part, so as to obviate the danger o f having the impact part interfered with by metal or air within the chamber. On the other hand, if it is found desirable to mount the impact art in the forward portion of the bullet, as i ust-rated in Fig. 2, so as to get urthe benefit of the compressed air back of it, the chamber should be of approximately the same cross section as the impact part, as

illustrated in Fig. 2 in dotted. lines.

'Ihe chamber can, of course, be filled with any desired material such as not to materially interfere w ith the action of the impact part or its -freemotion therethrough, and the impact part can be secured in position at any point and by any desired material. I have suggested lead but any one of many other substances could be employed.

, The use and operation of my invention is as follows: When a projectile is discharged at a target, for example a plate of steel, it is found desirable to have the forwardlend of the projectile closed in order that it may properly travel through the air and strike the target in the proper manner. If the forward end of the projectile be open so as to leave an annular cutting edge and if it strike the target squarely with such cutting edge, it is clear that the effect will be to make an annular indentation or fracture in the plate where the annular cutting edge of the prejectile strikes it. This, however, will tend to retard the bullet and if there be at such moment Within the bullet an impact art free to move forward inde endently of t e rest of the bullet er projecti e and strike the plate within such indentation, it is clear that the tendency would be te force the metal within the indentation, in other words the disk, out

and make a hole through the plate. Through this hole the entire projectile can then freely Broadly speakin the essential elements ase and its explosives, if any there be within seem to be a bullet ody with a forward anit can have their efl'eet on the op osite side of the plate. Now in this form o bullet or projectile adapted to perform this service, which is my invention, there may be various ways of supporting the im act part which is destined to punch out t e disk. I have shown it as supported Within the chamber back of the cuttinged e, either by means of its connection to the fil ing plug or b lmeans of its association with the materia at the bottom of the chamber. Where, as in these cases, the impact part is not adapted to substantially fill the opening and is not intended to first strike the target, it is desirable, in order that such impact part may have free movement that it be smaller in cross section than the chamber, and that the relation of the arts be such that the filling material whic remains in the chamber after the first contact with the target shall not plug the chamber and prevent the free motion of the impact art. The impact part is held so that it oes not move at all times with the body of the projectile as if continuous therewith, for in both of the forms shown it is dislodged either'by the first impact of the lilling material with the target or by the impact part or cutting edge with the target. If, as above explained, it is thought desirable to utilize the compressed air to nally force the impact part forward, then the impact part should be placed forwardly in the chamber and should be approximately the same cross sectionV as the chamber, as illustrated in dotted lines in Fig. 2.

nular cutting edge and chamber a yieldin filler to close the opening of the c amber an form the nose of the bullet, but of such a nature as not to pxerform any material function in fracturing t e target, and an impact part carried by the bullet within the chamber and adapted to move independently of the bullet and to effectively stri e the target after the cutting edge has performed its first function. It is with this sense that I have used these several terms.

I claim:

1. In a projectile the combination of a body with a forward annular cutting edge and chamber, a yielding filler to close the chamber opening and form the nose of the Eullet, and an impact part'within the cham- 2. In a projectile the combination of a body with' a forward annular cutting edge and chamber, a yielding filler to close the chamber opening and form the nose of the bullet, an impact art within the chamber, and secured to the ullet body.

3. In a projectile the combination of a body with a forward annular cutting edge and chamber, a yielding filler tO close the chamber opening and form the nose Of the bullet, an Impact art within the chamber and secured to the ullet body near the bottom of such chamber.
