- To all whom it may concern r Be it known that I, WILLIAM R. GULIcK,

a citizen of the United States, residing at 93 Garrison avenue, in Jersey City, county of Hudson, State of New Jersey, have invented certain new and usefulv Improve, ments in Projectiles, of which the following is a specification.

The invention relates to projectiles for rifled fire arms or ordnance and one of the primary objects of the invention is to provide means whereby the projectile will submerge and hold its true course upon coming in contact with aliquid 'such as Water instead of ricochetting therefrom.

ance of the air to the projectile in its flight may be diminished. The various other objects of the invent-i0 will be more fully set forth in the following descriptionof one form of projectile embodying the invention which consists in the new and novel features hereinafter set forth and claimed.

R ferring to the accompanying drawings:-Figure l is a side view'of a horizontally positioned projectile. Fig. 2 is a side view at right-angles to that of Fig. 1, and Fig. 3 is a front View of the projectile.

The projectile may be of any desired form and type, for instance, it may be a shot or shell, and may be pointed at the head, rounded, or otherwise.

In the particular construction shown in the drawings the projectile A is provided with a head B of reduced diameter provided with a cap 0. A plurality of oppositely disposed members D having their peripheries Within the circumference of the body portion of the projectile are mounted upon or formed integral with the head. Said members are plain or flat flanges oppositely inclined preferably at a small or low angle with respect to the axis of the projectile so that one edge of each flange will extend for Wardly and outwardly, but within the circumference of thebody portion. The flanges are preferably arranged in pairs diametrically opposite each other and encircling respectively opposite halves of the reduced portion of the projectile. The flanges are of proper shape and configurationto accuratel balance each other while'the ro'ec- J tile is in its flight or passage. Suitable clearance space is provided between the ends of the flanges and the body portion of the project-ilein any suitable manner.

The rotary movement of the projectile which is imparted by the rifling of the arm or ordnance causes the flanges to cut through either air or water, thus tending. to secure a straight trajectory for the projectile and also tending to increase the velocity of the pro ectile, particularly through a resisting medium such as water. The flanges are so arranged that at least one of them must .en-

gage with the water prior'to the instant of contact of the body of the projectile therewit-hand on account of the rotary move- A further object of the invention is toprovide means whereby the normal res1st-,

ment of the projectile have the effect of preventing ricochetting and cause the projectile to follow its path beneath the surface. Y

By means of this construction I am onabled to'provide a projectile which will enter the water and which will follow its course for a considerable distance while submerged on account of the propelling action of the flanges due to the rotary move ment of the projectile. Not only do the flanges cause the projectile to submerge, but they also aid in the flight of the projectile through the air sincethe rotary movement of the flanges tends to penetrate the air blanket or cap which forms at the point of any swiftly moving body.

Although I have shown the projecting flanges secured directly to a reduced port-ion of the projectile it isobvious that they may be placed in any desired position provided they oppose and balance each other and provided also that suflicient clearance is provided in the rear of the flanges to permit the passage of a fluid such as air. or water with respect thereto.

It is obvious also that various other modifications and changes may be made in the construction shown in the drawings provided the means set forth in the following claims be employed.

Having thus described my invention, I claim 1. A projectile for rifled fire arms adapted to enter and keep its course through water comprising a body portion and a reduced end portion, flanges extending outward from the reduced portion and within the line of the body portion and mounted on opposite 'sides of the projectile and operatively in clined thereto for aiding the projectile to dive into Water and keep its course therethrough during the rotation of the projectile imparted by the rifling.

2. A projectile for rifled fire arms having a pair of similar flanges projecting laterally from the same adjacent its forward end, said flanges being equally and oppositely inclined and respectively encircling opposite halves of the projectile for aiding the same to pass from a medium of one density into a medium of different density and keep its course therethrough during rotation of the projectile imparted by the rifling.

3. A projectile for rifled fire arms having a reduced portion at one end and a pair of similar flanges projecting laterally from
