To all whom, it may concern:

' ger by the projectile.

Be it known that I, ARMAND MIEG, a subject of the King of Bavaria, residing at Leipsic, -in the Kingdom of Saxony, G'erman Empire, have invented a certain new and useful Improvement in lProjectiles and Cart-ridges, ot which the following is a specification.

This invention has chiefiy for its object to serve for firing short distances-as, for instance, for tirin g in drill. It may also serve for hunting, and-generally in all-cases where persons or other objects beyond the obj eet aimed at are to be as little as possible exposed to dan- The projectile is constructed with a short metallic shell of the same caliber as those dest-ined for serious long range and penetrative firing, but is of but slight specific gravity. It kis formed of two parts, the fore part and main body in one piece and a separately-formed bottom cap; but it may also be made of one single piece, or may consist of a metal shell or coating filled with a mass of little specific weight. In all cases the bottom or rear end of the projectile is made of a concave form, so that when the projectile is forced through the narrower grooves of the gun-barrelit maybe easily compressed together.' If the projectile is made of a coating filled with a light mass, as pasteboard, paper, wood, paper-pulp, 85e.,

' it will be necessary or convenient to have the filling material of acertain yieldingness, so as also to permit compression of the guiding coating part under the pressure ot' the lands and grooves when the projectile is passing through the barrel. Such projectile is provided in the center of its top or front with a bore of about 0.25 to 0.50 of a millimeterin diameter. This orifice reduces the weight and lessens the uis riva or momentum and catches the air, and thereby aids in reducing the velocity and contributes to shorten the range of the projectile. This bere also serves to make more stable the axis of rotation of the projectile and thereby lessen the pendulum vibration and increase the precision of tiring within the short range for which my improvement is adapted. In projectiles consistin g of a coating with a filling the'bore may extend rearward near to theconcave bottom, so'j as to ferm an axial canal for catching the air. To .such projectile having a small weight, a

ot powder in the cartridge-case.

ished vis rifa is given bya diminished charge This lessens yet more the momentum, the following arrangement b'eing made in respect to the relative cartridge-case. The peculiarities of the lessened velocity and an essentially-diminentire construction reduce greatlythe range setting form a light but reasonably-firm fillsing. This filling, after Vits solidifcation and drying, is perforated lengthwise in the midst, or is in any other convenient way provided with a priming-canal-which is brought by branch holes into communication with the flash-holes in the rear or bottom of the eartridgelcasc. The proj eetile is not forced backward so l ar into the cartridge-case as to touch the front surface of the filling mass. The parts are so formed and adjusted as to leave a space between the bottom of the projectile and the filling mass, which space holds the charge of powder, and therefore is so calculated that the quantity of this charge corresponds to the weight of' the projectile andto the range to be attained. The powder may, for attaining larger ranges, ll also the een# tral primingcanal. Through limiting the powder-room and powder of the cartridge according to the weight of the projectile, respectively, through a thereby diminished charge ot' powder, the object desired may be attained with certainty-that is, a projectile striking with accuracy at a short range-but limited in its efficiency to a very short distance beyond the object aimed at, so that in shooting practice in the open air there will be little or no risk in entering or leaving the ground or otherwise occasionally moving behind the target at a distance ot about one hundred yards beyond, and consequently there will be no necessity to bar such grounds. The accompanying drawings form a part ot' this specification and show some examples of these projectiles. All are central longitudinal sections.

Similar letters of reference indicate corre- IOO spending parts in all the figures where they appear. r

` Figure l shows a projectile consisting ol a front part a, with a bottom cap b litted over it, provided with a concave rear face b'. The parts a and b b are stamped from copper or analogous metal or alloy and are forced together, and are through soldering, sweating, or other convenient Way united strongly. The space between contains a light filling c of plas- 1er or thelike. A holec extends along the axis from the front nearly to' the rear. This shows also the arrangement of the cartridge-case d with its A cap g and the provisions for leading the tiretherefrom to the front. The cartridgecase is'largelylled with a mass e; but between the sameand the projectile there remainsa free spacef for the'charge of powder. rlhis powder is in communication with the Hash-holes at the rear of the cartridge-case by means of priming-canals e' and e2.

' Fig. 2 'shows a projectile 'having the bottom cap b with its cylindrical sides fitted within the front part or coating a.

Fig. 3 shows a projectile with a coating a and' concave bottom b made in one piece. This may be conveniently made bydrawing tirst a vcup with a close concave rear and an open front, corrugating the front and closing it together or nearly together by a concave die. Such treatment makes the front a little thicker and heavier than the other parts. f

Fig. 4 shows a projectile consisting of -coatingaand lilling c, the latter being molded ing c and a longitudinal canal c in the filling.

This is the projectile in Fig. 1 detached from the cartridge and also from the bottom cap..

I claim as my inventionl'. In a cartridge for drill practice, the long shell d, corresponding to the ordinary cartridge, inert filling e, passage c to be filled with powder, and tiring-cap g at the rear, in combination with a projectile comprised of two shells a. and b b' and an inert filling c, arranged, as shown, so as to obtain a snflicient powderchamber f between, all adapted joint operation. as herein specified.

4 '2. In a cartridge flor drill practice, a projectile composed of a hollow metallic shell with a concave base b and a supporting-filling c, of light material, having a central hole or bore a', open at the front and closed at the rear, adapted to serve as herein specilied In testimony whereof I have hereunto set my hand, at Leipsic, this 17th day of November, 1891), in the presence of two subscribing witnesses.
