SPECIFICATION forming part ol' Lettera Patent No. 369,459. dated September 6, 1887. Application led April i8, 1887. Serial Noli?. (No model.)

To al? when?, 59mg/ concern:

Be itknownthat I, Joni: McCRnanY, a citi zen of the United States, residing at Webberville, in the county vof Ingham and State of projectiles for rire-arms, the object being to so arrange dynamite Within the same in relation to the gunpowder and percussion-fuse therein ,that theA projectile can be handled Without more than the necessary danger, an accidental explosion will be avoided, and the dvnamite vill be exploded, not directly by the percussion-fuse,but from the ring ofthe gunpowder thereby.

VThe invention 'consists in the construction and n ovel arrangement of parts, hereinafter described, embraced in the appended. claims, and illustratedin the accompanying drawing, in which the ligure represents a central longi- =tudinal section of the improved projectile,

fully showing the construction and arrangement of the interior.

Referring to the drawing, Adesignates the shell or cylinder ofthe projectile,made of steel plate, and having the base ofthe conical ball or.n1issile B litting on its open end down to the circumferential shoulder' b b of said missile, and secured in place thereon by the series oi" steel pins b, as shown. The ball or missile is provided `with an arial opening, in which rests the onterpart or the ring-pin @,with its front end, c, extended outward and prevented froidsliding inward by the transverse pin c', which passes through suitable openings in the missile and hiring-pin.

Dis a cylindrical case, of pasteboard,occu

pying the interior ol'the shell below the missile,

and having an axial opening through it for the accommodation of tieinner part, (l, ofthe firing-pin @which ir rt su rounded Within the casing` bythe e ferated tube E, made of the linest y. pasteboard.

The inner end ot' the 'ring-pin is somewhat reduced in size, and has litt-ed upon its extremity the percussion-cap F a short distance above the central boss, f, on the interior o the base of the shell A. l

G is a layer of coarse gunpowder inelosed in sheets of tissue-paper, g g,both on its inner and outer sides, and surrounding the perforated tnbe E foi' its entire' length.

vThe interior of the cylindrical ease D is filled with dynamite, (designated by HJ which is kept from immediate contact with the gunpowder by the tissue-paper, and also from contact with the ring-pin.

The described projectile may be made of 6o suitable size to be tired from guns of any caliber, and is necessarily very destructive, as the explosion of the dynamite takes place at the point at which the shell strikes, so that it would shatter at said point the heaviest armor that the largestyessels could bear, and in field service would 'make any protection except earth more dangerous than the open field.

When the shell strikes after firing,tlie projecting point of the firing-pin is driven in, the impact breaking the pin cf, and the cap F is exploded on the bossjliring the gunpowder, which explodes the dynamite.

The explosion is the more eiiective from being directed forward, the percussion-fuse being tired at the rear of the shell.

Having thus described my invention, l claiml. In a projectile for fire-arms, the combination of the cylindrical shell, the ball or ymissile secured in the front end thereof, the

dynamite in rear of said missile, the tube of finely-perforated pasteboard ruiming axially through the shell in rear ofthe ballor missile, the layer of gunpowderwrapped on each side with tissue-paper surrounding the perforated tube, and the percussion-fuse, substantially as described, acting through said tube and firing in the rear part ol' the shell, substantially as specified.

' 2. vThe hereiiidescribed projectile, consisting ofthe cylindrical steel shell A, provided with the central firing-boss, j', on the interior j of its base,the ball o r missile B,secured to the shell by the steel pins b, thefiring-pin C, se-

projecting out- In testimony that I claim the foregoing as xomy own I have hereto afxed my signature in presenceof two witnesses.

JOHN MCCREARY.
