- To all whom it may concern:

Be it known that LRICHARD B. DOUGLAS, a citizen of the United States, residing in the city, county, and State 'of New York, have 5 invented a new and useful Improvement in Projectiles, of which the followingis a specification.

My invention relates to projectiles to be used in various descriptions of fire-arms and guns of whatever caliber, the object being to provide for greater accuracy in forcing the projectile through the atmosphere, either against or transversely to a strong wind, more especially at long range. I attain this object by means of the contrivance' illustrated in the accompanying drawings, in which- I igure 1 is a horizontal view of my cartridge as it appears when complete and ready the piece. A is the cartridge-shell,-being of the description now in ordinary use. B is that portion of the projectile which extends beyond the shell. B is the exposed part of the metallic steering or guiding rod, which passes through the projectile B longitudinally. b is the front head-piece of the rod B. Fig. 2 is a sectional view of the difi'erent parts of the cartridge, showing the diii'erent features of my invention. A represents the shell; A, the vacant space in the fore'part of theshelhinto which the projectile B is inserted.

' A is a view'of the cover or wad of the pow-' der-charge, upon which the projectile rests. a is a cavity or recess in the cover or wad A, into which the burr or rivet, formed at the rear extremity of the guiding-rod B',is seated in'such manner that the whole force of the charge i's-exerted upon the projectile proper atpoints sufficiently beyond its center to pre-' vent: the forcing of the guiding-rod into its base. 7 B is the projectile proper, showing the passage of the guiding-rod longitudinally the position of through its center. B shows the guiding-rod after the discharge of the explosive within the cartridgeshell. B is a flexible button or other attachment placed upon the rear extreme of the guiding-rod B,

. and answering the same purpose as the feathered attachment of an arrow. This button or its equitalent may be made ot': any suitable material and of; any desired form. I; is the burr or rivet at the rear -ex tremity .0f the guiding-rod B, to prevent thedetachment or slidingoftot" the button B? in' the passage of the projectile upon or after its discharge. It will be observed that the guiding-rod B is so constructed as to play loosely within the projectile B, and thatimmediately upon the projectile being discharged from the shell A, the rod shifts its position and is drawn backward through the projectile, so as to bring the pointed cap b down upon the pointed end of the projectile B, thus givingthe projectile proper ametallic point. At the base of the projectile B there is formed a recess correspondingin size to the button B, so thatwhen the cartridge is formed complete the button B is held within the recess against the base of the projectile, and the cavity a in the shell cover or wad A is intended to receive the burr or rivet b merely. v

Fig. 3 is a perpendicular projection of the front end of the shell proper, A, showing the wad A with the central recess, a, therein.

Fig.4 is a perpendicular projection of the base of the projectile proper; B, showing the recess at B for the reception of the flexible button, or its equivalent, and the orifice B", for the reception of .the rod B.

The'niaterials used in constructing the cartridge are of the ordinary kind now in use, and may be varied accordingly, as desired, for gunsand pieces of large and small caliber.

I am aware that prior to my invention various devices have been used to insure accuracy in' the use of projectiles, particularly in respect to torpedoes; but I am not aware that any device similar to that embraced in myinvention has ever been suggested or employed in connection with projectiles discharged from the chamber of a rifle r gun barrel.

I am also aware that the combination of the charged metallic shell and projectile proper to be. used in arms of various kinds is not new.

I therefore make no claim for such combination; but a What I do claim as my invention, and desire to secure by Letters Patent, is-- The combination of a rifle or gun projectile" formed with a sliding and revolving rod or axis having a flexible burr or feather atits rear extreme, with the metallic cartridge shell, substantially as and for the purpose specified.
