Generally, devices of this type include a vessel for carrying a sedative fluid having a hypodermic needle attached thereto for allowing the fluid to pass from the vessel into the target. These elements are normally in corporated into a suitable structure or casing such that the completed assembly may be fired from a rifle or pistol.
Devices of this type have become popular in recent years in game preserves and the like where it is often necessary to capture wild animals. Sedative devices have proven to be much safer for the game handlers and much more humane to the animals being captured. It has also been contemplated to use such devices in the area of law enforcement to avoid the use of a fatal force to stop fleeing criminals. I-Ieretofore, none have found wide acceptance because they normally lack the dependability required in situations where the user is dealing with human targets rather than animals. To be effective, a device of this'type must have range and accuracy as well as the portability to be carried comfortably and employed rapidly.
In order to meet these requirements, the device should be made similar to a conventional bullet or cartridge and possess similar trajectory characteristics. In other words, the ideal situation would be that the sedative projectile device could be used interchangeably with conventional ammunition in the same fire arm.
The best teaching of a device of this type is disclosed in the US. Pat. No. 3,584,582 to Muller. However, due to the weight distribution of the various elements it is apparent that the projectile has a tendency to tumble in flight and consequently the needle may not puncture the target, resulting in non-delivery of the sedative fluid.
It is, therefore, an object and feature of the instant invention to provide a sedative bullet which includes an outer casing member, at least a portion of which is collapsible; a fluid carrying vessel supported within the casing member, the vessel including fluid injection means; fluid means disposed within the casing member for movementin response to the collapse of the collapsible portion; and discharge means for coacting with the moving fluid means for discharging the vessel.
Other objects and attendant advantages of the instant invention will be readily appreciated as the same becomes better understood by reference to the following detailed description when considered in connection with the accompanying drawings wherein:
FIG. 1 is a perspective view, partially broken away, of a-preferred embodiment of the instant invention;
FIG. 2 is a longitudinal, cross-sectional view of the instant invention as shown in FIG. 1; and
FIG. 3 is a longitudinal cross-sectional view of the instant invention of FIG. 2 striking a target.
Referring to the drawings, a sedative-delivering projectile or bullet assembly is shown generally at 10. The bullet includes an 'outer casing member generally indicated at 12, at least a portion of which is collapsible. The collapsible portion comprises a hollow nose portion 14 which is made of a soft, collapsible rubber. The remainder of the outer casing is a substantially cylindrical shell 15 which is made of a stiff material such as a hard plastic. The nose portion 14 is sealed to the forward part of the shell 15 by means of a ring 16 which locks a portion of the nose 14 into a circumferential groove 18 disposed in the forward end thereof. The casing member 12 also includes an explosive charge means comprising a firing cap 20 for propelling the bullet 10. An explosive change means 20 may be of any conventional construction and, in this case, is a standard shotgun-type firing cap. The firing cap 20 is mounted on an end of a cap member 22 which is threadedly disposed within the end of the shell 15 thereby sealing the end of the shell 15 closed.
The bullet 10 further includes a fluid carrying vessel 24 for carrying a liquid sedative 26. The vessel 24 includes fluid injection means comprising a hollow needle 28. The hollow needle 28 is in the form of a standard hypodermic needle and provides a passageway for the injection of the sedative fluid into the target. The vessel 24 is supported within the casing member 12 by means of a plurality of longitudinally extending vanes 30 which support the vessel 24 in spaced relationship with the interior of the casing member 12. It is contemplated that the shell 15 of the casing member 12 and the vessel 24 may be formed by a single molding process which would also produce the vanes 30. This molding process would simultaneously incorporate the hypodermic needle 28 in the assembly. The vessel 24 is provided with means for discharging the sedative liquid 26 from the vessel 24. The discharge means in cludes a piston member 32 which is slideably disposed within the vessel 24. The piston member 32 includes a sealing ring 34 for providing sealing engagement with the interior of the vessel 24 to prevent the sedative fluid 26 from escaping around the edges of the piston member 32.
Fluid means comprising a fluid 36 is disposed within the casing member 12 and fills the volume surrounding the vessel 24 including the hollow nose portion 14. The fluid 36 is one which has a relatively high specific gravity; in other words, it may be best described as a heavy liquid or fluid the purpose for which will be hereinafter described.
The nose portion 14 of the bullet 10 also includes a guide member 38 disposed at the apex thereof for permitting the needle 28 to pass therethrough. If the guide member 38 is not provided, the opening in the needle 28 could possibly become plugged, thereby preventing the discharge of the sedative fluid 26 from the vessel 24. A protective plug 40 is also provided which protects the end of the needle 28 prior to using the bullet 10. The plug 40 is adapted for removal immediately prior to using the bullet 10. The size of the needle 28 and the physical characteristics of the heavy fluid 36 are such that the heavy fluid 36 will not flow through the guide member 38 after the plug 40 is removed.
When the bullet 10 is fired and strikes an object, the nose portion 14 collapses and the needle 28 is driven into a target 42 through the guide member 38 as shown in FIG. 3. Thecollapsing of the nose portion 14 simultaneously forces the heavy fluid 36 toward the rear of the casing member 12 and the-resulting pressure forces the piston member 32 forwardly. The forward motion of a piston member 32 forces the sedative fluid out of the vessel 24 and discharges it into the target 42 through the needle 28.
Thedesign of the bullet 10 is particularly advantageous because the heavy fluid 3 occupying the nose portion 14 of the bullet distributes the weight such that the bullet 10 does not have a tendency to tumble. In other words, the front of the bullet 10 is slightly heavier than the rear portion due to the heavy fluid 36 in the nose portion 14 and therefore the nose portion 14 will lead during flight. Furthermore, supporting the vessel 24 on the longitudinal vanes 30 allows substantially uninhibited flow of the heavy fluid 36 from the nose portion 14 to the rear of the casing member 12 to move the piston member 32.
Preferably the heavy liquid 36 is nontoxic and is adapted to lubricate the needle 28 to aid the penetration thereof in the target 42.
The sedative delivering bullet assembly of the instant invention is readily adapted for use by law enforcement agencies because it is designed to be quickly and easily substituted for standard ammunition in a conventional firearm. In the preferred embodiment the sedative bullet is particularly adapted for use in a shotgun-type weapon, however, changing the size and type of firing cap will readily provide a sedative bullet for other weapons such as hand guns. It is also noted that the sedative bullet is of a simple design and may be manufactured easily and inexpensively.
The invention has been described in an illustrative manner and it is to be understood that the terminology which has been used is intended to be in a nature of words of description rather than limitations.
Obviously, many modifications and variations in the instant invention are possible in light of the above teachings. It is, therefore, to be understood that the instant invention may be practiced otherwise than as speciflcally described and yet remain within the scope of the depending claims.
