HYPODERMIC BULLET .Application led June 21,
M y invention relates to a bullet or shell in which the bullet portion proper includesor is replaced by means for injecting into the target aluid or chemical effective to drug.
or paralyze the animal struck. One object is to provide a hypodermic or injector-bullet for game shooting. Another object is the provision of means'for preventing theseparation of the hypodermic from the target or animalstruck. Another object is the provision of means for insuring an immediate and relatively complete discharge of the chemical into the body of the animal upon contact of the bullet with the animal.
Other objects will, appear from time to time inthe course of the specification and claims.
I illustrate my -invention more or less diagrammatically in the drawings, wherein- Figure 1 is an elevation of the bullet with parts of the cartridge case broken away;` Figure f2,A illustrates the charging of the bullet; Figure 3' is a longitudinal -section of a charged bullet;
Figure 4 1s a longitudinal section of a bullet from which the hypodermic charge has -been withdrawn; and
Figure 5 is a section on the line 5-5 of Fi ure 4. l
ike parts are indicatedby like symbols throughout the specification and drawings.
A indicates any suitable cartridge having a rim A? limiting its forward movement in the chamber of the rifle, shotgunor other arm with which it is used. Obviously any desired form of shell or cartridge may be employed, its details forming no part of the present invention. A2 propulsive charge of powder or the like.
Seated in the shell is the cylinder B which may be held in position either by its close tit with the interior ofthe cartridge A or by any suitable substance B1, such as wax or the like. B2 generally indicates a closure member for closing the forwardly open end B5 of the cylinder B. It is axially apertured as at B4 'such aperture extending inwardly through an inward-extension Bts which may be circumferentially channeled or grooved as at 5f B.

aperture inv communication with the. aperture B4. It receives the screwthreaded expanded portionB9 of the hollow hypodermic needle B8 with its sharp point B10. B11 indicates any suitable prong or barb.
.Mo`unted within the needle B8 is a'hollow pin O forwardly sharpened as at O1, Its rear end O2 engages an inner closure or seal O3 of lea'd or the like, which normally sep-- arates the aperture or passage B4 from the interior passage of the needle B8 on the pinO. l) lndlcates a cylindrical sacor container which may be of any suitable yielding mater1al, for example rubberf One end is secured about the member B5 as by wires or cords D1. The other end is closed by a yielding cylindrical plug D2. I E E indicate vanes each of which has atA lts base the rounded or inclined surface E1.
It will be realized that whereas I have descrlbed and shown a practical and operative device, nevertheless many changes might be made in the size, shape; number and disposition of partswithout departing'from the spirit of my invention. I therefore wish my descrlption and drawings to be taken as in 'a broad sense illustrative and diagrammatic rather than as limiting me to my specific showing. v The use and operation of my invention are as follows:
It is extremely desirable in game hunting and particularly in big game hunting to be able to take animals alive. This is particularly the case in hunting specimens for menageries, although of course mybullet'is not limited to suchv use. I have therefore developed a bullet which may be shot rom agun as with an ordinary bullet or cartridge, or which may be used as a rile grenade. The bullet, instead of being formed to penetrate and kill or wound the animal or target, is armed with a hypodermic needle which penetrates the skin of the animal. When the needle hits the animal the pin C1 is thrust back through the needle against the seal or inner`closure C, which it ruptures. When ythe closure is 'ruptured the compression of the yielding sac forces the hypodermic charge outwardly through the pin and into the animal.
The barb prevents the displacement of the bullet from the animal and insures that once the needle has sunk into the skin of the animal and the charge has been released, the
` charge will be able to flow uninterruptedly through the needle until it is exhausted. The
vanes E hold the bullet in its course and prevent tumbling. The inclined or curved surfaces E1 cause, in response to the eXplosion ofthe charge A2, a rotation of the bullet body about its aXis of forward movement, thus further tending to keep 'the bullet true in its path, with the needle forwardly eX- tending along the aXis of -forward movement of the bullet.
In lling the bullet, as illustrated in Figure 2 any suitable filling. container, diagrammatically indicated as G in Figure 2, may be employed.
Associated with the filling container G may be the needle Gr1 which may be thrust through the plug D2 to permit the charge to be expelled fromthe container G in order to fill the sac D under pressure. When the needle Glis withdrawn the yielding substanceof the plug D2, which may for example be of rubber, seals up the hole, which sealing tendency is further increased by the inward pressure against the plug D2.
I claim: Y. l. In a hypodermicl bullet, a bullet body, a
V needle forwardly projecting therefrom, a
container within the bulletbody, adapted to contain a chemical charge, a closure normally interposed between such container and the needle, and means, responsive tothe impact of the bullet against its target, for open.- ing such closure and for permitting the escape of the charge through the needle.
2. In a hypodermic bullet, a bullet body, a needle forwardly projecting therefrom and normally xed in relation thereto, and means within the bullet body for normally maintaining said charge under pressure.
3. In a hypodermicbullct, a bullet body,
