UNITED STATES PATENT OFFICE.
JOHN W. ANDERSON, OF ALLEGHENY, PENNSYLVANIA; ADELLA M. AN- DERSON ADMIN ISTRATRIX OF SAID JOHN W. ANDERSON, DECEASED.
PROJECTILE.
Patented Oct. 31, 1905.
Application filed June 27, 1904:. Serial No. 21,825.
To all whom it may concern:
Be it known that I, JoHN W. ANDERSON, a citizen of the United States,residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented or discovered certain new and useful Improvements in Projectiles, of which improvement the following is a specification.
The invention described herein relates to certain improvements in armor piercing projectiles, and has for its object a construction whereby the projectile will be caused to be tipped or turned immediately prior to impact of its body with the surfaces of the armor or protective deck and will thereby' be so tilted or changed in its line of movement as to change the angle of its axis to the surface of the armor or deck. As now constructed armor-piercing projectiles whose points are made exceedingly hard and conical will when they strike upon an inclined surface and the curved rotected deck of the war vessel be deflected unless the angle formed by the axis of the projectile and the surface of the armor at the instant of impact are greater than half the angle formed by the sides of the projectile. In order to prevent or lessen this glancing of the projectiles, I provide suitable readily-frangible means which will strike the armor or deck slightly ahead of the project ile, and so tip or turn the projectile that the angle of its axis with the plate will be increased.
The invention is hereinafter more fully de scribed and claimed.
In the accompanying drawings, forming a part of this specification, Figure 1 is a side elevation of' the projectile having my improvement applied thereto; and Fig. 2 is a view similar to Fig. 1, illustrating a modification of my improvement.
In the practice of my invention the projectile 1 is of the usual form of construction, having the conical piercing-point. Such projectiles unless the point of impact on the projectile coincides approximately with its apex will be deflected without producing any material injury to the plate. In order to insure or increase the penetration of the curved deck-plates, even when the direction of movement of the projectile prior to im act is at an angle less than a right angle to t e surface of the plate, I provide means whereby the direction or line of movement of such projectile shall be changed and the projectile caused to strike on the plate with its axis at an increased angle to the surface of the plate and at the same time break up and leave the projectile. To this end a frangible ring or collar 2 is placed on the projectile near its point, the said ring or collar being so constructed and arranged on the projectile that its front or biting edge a will strike and bite into the plate ahead of the impact of any portion of the projectile if the line of movement of the latter is not substantially at right angles to the plate. The biting of the forward edge of the ring or collar will retard the under side of the projectile, so that its rear end will be turned out in the direction of the arrow 1), thereby bringing the axis of the projectile to such an angle that its point will engage the plate, and thereby insure the penetration of the latter by the projectile to the plate and, it is believed, aid and cause the projectile to pass through the plate. In order that the ring or collar may not operate to materially retard the penetration of the projectile, it is made easily frangible, so that it will be broken up and leave the projectile free so soon as it has performed its tipping or turning function. T he ring or collar is made, preferably, of an internal contour to fit snugly on the projectile and can be placed at suchdistance from the point as not to interfere with the use of the soft point or nose-piece now usually employed with armor-piercing projectiles. If desired, accidental displacement of the ring or collar may be prevented by a pin 3 driven into a small hole in the projectile or by a set-screw 3, which preferably has its head countersunk, as shown.
I claim herein as my invention A'n armorpiercing projectile having a piercing-point in combination with a frangible ring or collar arranged on the projectile in the rear of said point and adapted by engagement with the armor or plate to change the direction of movement of the projectile and aid in its penetration,substantially as set forth.
In testimony whereof I have hereunto set my hand.
JOHN WV. ANDERSON.
