Application filed October 10, 1910. Serial No. 586,274.

dent olf Bredeney, }erinai'iy, have invented` ctfrtain new and useful Improvements in' ylrojectiles, of which the following is a speci- Patent No. 932,214- dated ft), a projectile is disclosed need to he used with a gun or 'i 'Y' device having a loore lor duiding-simili oli the projectile, oject'ile possesses a .veight de- "dned to de on this shaft. Ou the shaft .here is provided a striking part which liniits the rearward n'ioveinent ot' the weight relative to the body of the projectile and el'l'ects the separation of the projectile from the att '.lhe part oi the shaft on which the weight made to slide is, for this purpose, suplilied with ribs and the weight with cori sponfiling grooves. The process of inak- .ing' these ribs: and `grooves is, however, tedieney and egipns'vc; The present invention :iiins the'ejfore at the sini'ilifying oi this shalt andI weight. Y

The.' object i in the present invention, reached by giving" the part of the shaft vvl creen the weight slides, a smaller dianteter than that of the here in the `gun; and hy supplying the slia'it with an alnitinent or stop at the rear end oi this small dian'ieter, which stop will contorni with the diameter olf the hof" in tl gun. vbid the smaller part oil the shalt passes through a hole ot the same diameter in the weight, so that, with the a stance oi centering-faces on the neiglit and on the gun, the i'oi'n'ler/will he in such a position', that its axis will coincide with thato'l the bore ot the gun.

One way l' carrying out the object of the invention is shown in the accompanying drawing, vv'herein the. projecting' device eonsists et' an ordinary gun and where the projectile is drawn in side View, partly in section: and the gun in longitudinal section outlined in dot and dash.

rlhe hotly of the projectile is ,indicated by the letter It, its guide-shalt l), its sliding' "eight K and the gun barrel (l, the bore of which is intended 'for supportingr the shalt The part of the shaft, along' which the weight li is lnadeto slide. iS a` smooth cylinder fl, protruding? through a suitable here lt ol' the weight K, and having a smaller diameter than the here ol2 the gun barrel. .At its rear end the shaft l) is provided with 4a stop or abutment d, which, as well as the shaft part (Z5, is cylindrical, said Stop d has a diameter corresponding to the caliber of the `gun and forms a striking hea'd which liiiiits the rearward movement of the weight l( ,relative to the hotly of thev projectile A. The gun has at the muzzle an outer cylindrical centering-face c1, This face cl of the gun barrel lits into a. suitably shaped recess in the weight- K, in such a manner as to provide a centering device for the shaftv and projectile. with respect to the gun barrel. AThe centering surface /v of the weight K is Vc ui \;ial with the bore 7c3 so that enough riction is obtain-ed between the weight and the gun, when the former has been pushed -over the inuzzlesurface c1, to prevent the weight being torn olf the gun by the friction forces occurring` in the bore k3 from the sliding' oi" .the shaft D.

Before the firing of the gun, the several. parts of the projectile will be in the position shown in the drawing.

in the bore 7c3 of the weight l which is eennected with the gun barrel; and partly by means of the stop d in the here of the gua barrel C. This guiding is equally as accurate as the one obtained by the ribs vprovided on the shaft of the projectile referred to in the beginning of this specification and it is further accomplished with considerably simpler ine-ans. f

V/Yhcn the gun is tired, the shaft l) will be driven one of the barrel, while the weight K remains on the `run until it is hit by the stop d ol the shaft. By the blow hereby produced, the weight, on the ,one hand, will he released from the gun ham-el, and the incvement of the shaft D, on the other hand will. be so much retarded, that the shaft will he separated from the body oit the projectile shortly after the tiring of the gun.

lV hat is claimed isz-- l. [t projectile having a. projectile lody, a shaft for guiding the projectile in thelgun or projecting device, said shaft having,l its entire cross-sectional area less than the dian'ieterot' the here, a stop formed with the Sha'lt of .substantially the dian'leter of the oore, driving` 'and non-restraining connection between the shaft and the projecting device, a weight loosely mounted on the The projectile issthenv L(guided partly by the shaft-shank Z5 shaft adapted to t' over the muzzle of the gun barrel to cooperate with the stop and effect the release of the shaft from the projectile body upon firing.

2. rEhe combination with a gun barrel, of a projectile having a projectile body, a cylindrical recess radially therein a weight constructed to fit over the muzzle of the gun barrel, a cylindrical aperture centrally of the Weight, a shaft having a cross-sectional area at one extremityv of substantially the diameter ofthe bore, a reduced diameter adjacent thereto conforming to the cylindrical aperture in the Weight, a reduced diameter adjacent thereto conforming to the cylindrical recess in the projectile, and operable to effect separation between said projectile body and the shaft upon firing.

3. The combination With a gun barrel having a bore, of a projectile having a projectile body, a cylindrical recess formed radially therein, a Weight provided with a central cylindrical aperture adapted to fit over the muzzle of the gun barrel, a shaft for guiding the projectile in the gun barrel bore having three diameters successively reduced and adapted to fit the gun bore, the Weight and the cylindrical recess respectively and operable to effect separation between said vprojectile body and the shaft upon firing.

4t. The combination With a gun barrel hav ing a bore, of a projectile having a projectile-body, a shaft for guiding the projectile in the gun barrel bore, said shaft having a portion of its length With its entire cross the stop and effect the release of the shaft from the projectile-body upon firing.

5. The combination With a gun-barrel having a bore, of a projectile having a pro-v jectile-body, a shaft for guiding the proj ectile in the gun-barrel bore, said shaft having a portion of its length of less diameter than the diameter of the bore, and another portion of its length of substantially the diame# ter of the bore and providing a' stop, a Weight loosely mounted on the reduced portion of the shaft and constructed to fit over andA have frictional engagement With the muzzle of the gun barrel; said engagement and the enlarged portion of the shaft providing a centering device for the projectilebody and shaft with respect to the axis of the gun-barrel bore,"and effecting the release of the shaft from the projectile body upon firing.

The foregoing specification signed at Barmen, Germany, this 20th day of September, 1910.
