(Cruz-26) The so-called divided casing projectiles, which are used for hunting purposes, are intended to.

stop the game as far as possible on the spot where it is 'hit, or at least to obtain an exit wound in Q; order to insure a 'good blood track fol-searchin for t the game.

In order to obtain this result, very many diiferent proposals have been made for the construction of such projectiles. Such proposals include inserting a transverse partition in the projectile casing, with the object of insuring that the front part of the projectile shall shatter on striking and penetrating the body of the game, and of retaining intact as far as possible the rear part of the projectile with its lead filling in order to secure penetration and an exit wound. v

The insertion of a continuous transverse'partition in the projectile casing involves difiiculties of manufacture and increase in cost, and likewise 2Q; prevents the use of nickel plated sheet metal as a casing or jacket material.

To simplify and facilitate the insertion of the" partition, the jacket has been made in two parts,

but this weakens the projectile to such an extent- 2 that it may be distorted or broken on passageitself, an annular fold beingmade at a suitable point in the jacket, whichfold has its sides in contact with each other, and has an internal #0:; diameter of such dimensions that escape or scat tering of the rear part of the projectile is prevented.

The invention likewise comprises a method of making the projectile by forming the annular f-t 'f01d in the jacket after the core metal for the rear or heel part of the projectile has been pressed into place. The core metal for the front part of the projectile is not pressed in until after the formation of the said fold, so that the partition or fold @Qgconstitutes the plane of separation of the two projectile cores, which cores may be of difierent hardness.

A projectile is thereby formed which has a onepiece casing provided in a simple manner with i an internal transverse partition which serves to retain in position the projectile-filling in the rear portion of the casing, so-that the projectile has a. considerable penetrating power and canv produce an exit wound, while the front part of the projectile is so constructed that it is shat' tered' on striking and penetrating the body of the game. I

The manufacture of the projectile is very simple and cheap because the internal flange-like annular wall can be made very easily by providing the'projectile casing, which previously has been provided with the rear halfof the filling, with a peripheral groove and then upsetting longitudinally the projectile casing until the groove is compressed to form an inwardly-projecting annular collar, which insures the internal sub-division of the projectile chamber and also determines the bursting zone. On the exterior of the projectile casing at the position of the internal annular collar, there is seen only a circular slit, since in the upsetting operation the initial groove is completely closed. One typical form of projectile embodying the invention is shown in the accompanying drawing, wherein: 89

Fig. 1 is a longitudinal section of an empty projectile jacket. v t p Fig. 2 is a section showing the same jacket with the metal of theheel core or core section inplace. V j

Fig; 3 is'a section showing the jacket with the heelcore and the groove from. which thepartition is formed. V

Fig.4 is a section showingthe partition, folded inwardly, from the jacket wall upon the heel core.

Fig. 5 is a section of the finished projectile. Fig. 6 is an elevation of the finished projectile. The projectile casing or'j'acket, which in the constructional example has a closed base but may be provided equally Well with an open base, is first filled to a suitable height with a lead charge 2, and an annular groove 3 is pressed in above said lead charge. By longitudinal upsetting of the jacket the sides of the groove are pressed inwardly, closing the groove and forming an inwardly projecting flat annular collar 3', which thus divides the projectile chamber. The front projectile chamber, which is still empty, is then likewise provided with a. lead filling or point core 4, and the tip and base portion of the projectile are contracted or formed, so that the finished projectile shown in Figs. 5 and 6 is obtained.

The inwardly projecting annular collar or fold determines the bursting or shattering zone and,

in addition, prevents the heel core from being forced forward. The said heel core 2 preferably consists of hard lead, while the point core 4, which is adapted to be flattened or shattered on 5 impact, may be of soft lead.

Upon striking a target such as the body of an animal the velocity of the projectile 'point is abruptly and greatly reduced, but due to its momentum the heavy heel section tends to maintain its velocity, with the result that the pointis flattened or spread, and its jacket torn apart;

practice the point core is often completely dis-,

persed, and the point jacket is frequently com- 5; pletely sheared off at the angle where it joins the fold 3, the heel section of the projectile with the fold 3 remaining intact. If the velocity is lower, and/or the target is flesh rather than bone, the point section may be .merely flattened '0; or mushroomed, and the projectile as a whole continue to advance. Adequate penetration of all possible hunting targets by projectiles having a wide range of velocities is thus insured.

As shown in the drawing, the fold 3, which is integral with the jacket 1 and formed therefrom by the sequence of simple operations heretofore described, is preferablyso located as toprovide both a heel section and a point section of sub-.

. stantial size, and likewise projects inwardly from '3 the jacket a suflicient distance to effect a sub-'- stantial separation between the heel and point cores. Applicant has thus in effect combined two projectiles in one. The point section is areadily deformable projectile which mushrooms on im- 53 pact with flesh, and the heel sections is a difiicultly deformable projectile which penetrates Applicant thus realizes the ideal of hard bone. e V

a projectile which produces the desired effect on the game, regardless of the range or the part of 5, the animal which is struck. I The new form of projectile or shell may also be employed, within the scope of the inventiornfor explosive projectiles, signalling projectiles and the like, wherein use is made of partitioned casings.

53 What is claimed is:

harder metal, and a partition 'integral with said jacket partially separatingsaid cores.

l. A projectile comprising a one-piece jacket, a point core of relatively soft metal, a heel core of 2. A projectile comprising a one-piece-jacket, a point core of relatively soft metal, a heel core of harder metal, and a closed fold in said jacket metal forming an inwardly extending annular transverse partition substantially separating said heelcore from said point core.

, 3. A'projectile comprising a one-piece jacket, a

point core of relatively soft metal, a heel core of harder metal, and a closed fold in said jacket metal forming an inwardly extending annular transverse partition substantially separating said heel core from said point core and protecting said heel core against deformation on impact of the projectile against a target. 7

4. A projectile comprising a one-piece jacket, a

,point core of relatively soft metal, a heel core of harder metal, and a closed fold in said jacket metal forming an inwardly extending annular transverse partition substantially separating said heel core from said point core, said fold facilitating the disruption of the point section of the projectile upon impact while protecting the heel section.

5. A jacketed projectile comprising readily deformable point and diflicultly deformable heel sections of substantially equal length, the junction of said sectionscomprising a fold in the jacket metal forming an annular; transversely disposed partition of substantial width, whereby the projectile is caused to separate at said partition on impact against atarget. 7

6. A projectile comprising a core and a jacket surrounding said core, said jacket comprising an integralinwardly extending closed fold forming an annular transversely disposed partition partially dividing said core into two sections each of substantial size, said fold extending inwardly for a substantial distance, whereby the sections are separated on impactof said projectile against atarget.
