SPECIFICATON forming'part of Letters Patent-No.A 338,849, dated March 30, 1886.

Application filed January 17,1885. Serial No. 153,137. (No model.) Patented in Belgium J une 23, 1884, No, 65,556, and in Italy June 3o, 1ee4, No. 11,059. l

.To all whom it may concern:

-Be it known that I, WILHELM LORENZ, of Carlsruhe, in the Grand Duchy of Baden and Empire 0f Germany, have invented certain new and useful Improvements in Compound Projectiles, (which have been patented in lBelgium J une 23, 1884, N o. 65,556, and Italy J une 30, 1884, No. 17,059,) of which the following is a specification.

This invention relates to the manufacture of compound projectiles; and it consists of a compound projectilel the core of which is melted onto the covering shell, which shell is coated with tin or other metal. The core or shell, or both, are provided with guide-rings that are melted on the same.

In the accompanying drawings, Figure 1 represents a vertical transverse section of a shell for my improved projectile. Figs. 2 and 3 are vertical central sections of my improved compound projectiles having guide-rings in the form of caps. Figs. 4, 5, and 6 are vertical central sections of projectiles with modilied forms of guide-rings. Fig. 7 is a vertical central section showing the projectile in the Fi 8 is a side View and section of another moditzled lform of a projectile with annular 'guidegrooves; and Figs. 9, 10, and 11 are sections of modified forms of projectiles in which the.

guide-rings are made integral with the shell. Similar letters of reference indicate correspending parts. l A My improved compound projectilesponsist, essentially, of a heavy metalcore or projectile and a. covering-shell of harder metal,which is united with the projectile in such a manner that 'they form in use one ignited whole. The shells may be made of one or more" parts. lhey are preferably made of steel, copper, brass, or other metal or alloy of metal possessing a high degree of hardness and sullicient ductility. 'lhe shells are made, preferably, trom' disk-shaped blanks in Vdraw-presses, according to the metal or the form of shell. 'llhey may be cast in molds or turned inalathe, er made in any other suitable manner. rlhe shells S are ,rst cleaned on the outer and inner surfaces, in the usualmanner, by means of acid,and covered at the outside and inside, er 'at the inside only, with a coating lof tin,-

zinc, or other metal, by any approved method; or they. are prepared in any other manner,

vso thatv the projectile, when introduced into least equal to the fusing-point of the metal of the projectiles, whereby the latter are united at the moment of insertion with the shells. The metal of which the core is made may also be' poured in molten state intothe shells, whereby, also, the desired union between the core and shell 'is obtained. The .core may be compressed more or less after it has been 4united with the shell, which pressing 'recommends itself when the cores have been cast Kin the shells and after they have somewhat cooled oil". y 4

= For guiding the projectiles in the barrels of the rearms,the shells S are either increased in thickness, asl at @Figs 4 and 10, or enlarged by bulging, as at r, Figs. 5 and ll, capro videdwith'one or more guide-rings, 1', as in Figs. 6 and 7, or with a cap, ra, that is placed over the vbase of the projectile, asv in Figs. 2, 3, and 5. lo properly inclose the core l), either the caps 1' or bottom disks, f, may be used, in' p Figsrl and 9. n

Fig. 8 shows a shell with annular guidegrooves r4. The guide-rings, caps, or bottom disks are also' coated with' tin. or other metal and molded onto the core,either partly er eutirely.- ln the case of the caps, theyv he I connected either at their inner .surface with the core or at the periphery with the shell.

The melting together of the core and shell maybe accomplished dreh-and then the guide ringsor caps specially melted on g or the cores, shells, and 'guide-rings or caps may loe united together at'on'eand the same time and by one.' operation. y

dimensions and weight. The compound projectiles with hard shells .and hardened points and cores united thereto by melting are ca- -pablefo't high resistance and possess great force ci' penetration. As the shells cannot, on striking an object, get detached from the cores, break, or give Way, and as the cores cannot crowd up or flatten, the compound pro jectiles differ advantageously from the projectiles heretofore known, in which the shells or coverings are not united with the cores, and

in which the shells, when striking the object, either crowd up or detach themselves from the cores, so that they pass in detached parts through the soft parts o f the object and exert an injurious influence on the wounds caused thereby, while they can, owing to their form and size, be removed only with difficulty from- .the wounds. Another advantage is, that the cores and shells partake of asimultaneous rotation, whereby a better trajectory and a greater accuracy in hitting the object are obtained.

Still another advantage is, that by the tinning f or other preparation ofthe shells-Tas, for instance, in steel shells-the corrosion ofthe sameis prevented and blood-poisoning obviated when they penetrate the lieshy parts, which would surely take place with unprepared and fragile shells of steel, copper, brass,l

or other metal.

Having thus described my invention, I clalm as new and desire to secure by Letters Patent- 1. A compound projectile the core of w h1ch is melted to the coveringshell, substantially as set forth.

' 2'. -A compound projectile the core of which is melted to the covering-shell, 4which latter is coated with tin or other metal, substantially I as set forth. l

3. A compound projectile composed of a core and covering-shell, the fermer being melted to the shell, andg'uide-rings melted to the core or'shell, or both, substantially as set forth. t

In testimony that claim the foregolng as my invention l have signed my name 1n presence of two subscribing witnesses. t
