Crockford, Chamblee, and Frank A. Hayes, Athens, Ga., Seldom D. Feurt, Memphis, Tenn, and James H. Jenkins, Athens, and Harold C. Palmer, Douglasviile, Ga., assignors to Palmer Chemical 8: Equipment Co., 'Inc., Douglasville, Ga.
Filed June 17, 1963, Ser. No. 290,275 10 Claims. (Cl. 102-92) This application is a continuation in part of our co-pending applications, Ser. No. 35,233 filed June 10, 1960, now abandoned and Ser. No. 161,895 filed Dec. 26, 1961, now abandoned. The instant application also covers further improvements to the structure shown in re-issue United States Patent Nos. 2,854,925 issued Oct. 7, 1958 and 2,923,423 issued Feb. 2, 1960. The instant invention is also utilized in connection with our novel method of capturing animals.
This invention relates to an injecting projectile which finds its principal application when utilized to inject a liquid drug into an animal at a distance therefrom.
In our issued patents We have previously employed the combination of a liquid and solid gas propelling reactant which would produce a gas upon interaction and thereby propel the drug into the body of the animal. The reactants were not adapted to interact until the proper time. In our prior application, Serial No. 35,233, of which this application is a continuation in part, we disclosed a structure wherein a firing pin would cause chemical explosive material to explode upon impact of the projectile with the animal and the gases produced would thus propel the material contained within the projectile. This structure constituted a great improvement over the structure shown in our re-issued patents in that the triggering was considerably more positive, the propelling reactants did not disintegrate on standing, and loading of difficult to handle materials within the projectile in the field was obviated. The structure of Ser. No. 35,233, on the other hand, also had a number of disadvantages involving possible inadvertent triggering of the mechanism because of the type of propellant employed or insufiicient propulsive force because of the small quantity of propellant that was required to beutilized. The structure shown in Ser. No. 35,233 is shown in this application in FIGS. 1 through 6 thereof.
The structure shown in FIGS. 7 through 13 of the instant application constitutes considerable improvements over the structure shown in Ser. No. 35,233 and is essentially the structure disclosed in Ser. No. 161,895. This structure provides a positive device which should operate one hundred times out of one hundred. In this connection, of course, the reader can see the disadvantages of finding an inoperative projectile when the operator of the device is confronted, for example, by a charging lion.
The projectile of this invention may be briefly described as comprising a container adapted to have a drug disposed therewithin. Injection means (such as the conventional hollow needle) and a drug propelling member are in operative relationship with the container. Explosive means are in operative relationship with the drug propelling member and are actuated by change of motion (preferably upon impact) of the projectile upon an animal.
The form of the invention shown in FIGS. 7 through 13 may be briefly described as a projectile for drug delivery comprising a liquid drug holding container, injection means upon the container (preferably a hollow needle communicating with the interior thereof), a drug propelling member slidably movable within the container, and explosive container connected to the drug propelling member open at one end thereof and adapted to support explosive material adjacent its closed end, a firing pin slidably movable within the explosive container, and spring means connected with the firing pin normally holding the firing pin in spaced relationship with the closed end of the explosive container.
In the preferred modification of this invention shown in FIGS. 7 through 13 the drug propelling member is cylindrical and is provided with a wing member opposite the hollow needle. The drug propelling member is also cylindrical and bears ridges abutting the inner surface of the container. The drug propelling member is further provided with a cylindrical recess therewithin open at the top thereof.
The explosive container is likewise cylindrical and is open at one end thereof. A securing portion is disposed adjacent the open end of the explosive container. The explosive container is frictionally disposed within the recess in the drug propelling member, with the open end of the explosive container being adjacent the open end of the recess.
The firing pin in the form of invention shown in FIGS. 7 through 13 has a body portion and a narrower projecting actuating portion while the spring means comprise a coil spring abutting the junction between the body portion and the actuating portion of the firing pin with the actuating portion of the firing pin being within the coil spring.
The explosive material which is used in the form of invention shown in FIGS. 7 through 13 is of two classes. The first, a secondarily detonatable explosive material, such as black powder, is disposed within the explosive container adjacent its closed end. A barrier member is provided in adjacent relationship on one side thereof with the secondarily detonatable explosive material, and is provided with an opening therewith. Primarily detonatable explosive material, such as mercuric fulminate is disposed upon the opposite side of the barrier member and in normally spaced relationship with the firing pin.
Various specific constructional features may be also part of this invention in the preferred modification thereof, although not strictly necessary for the operation thereof. These additional features are set forth in the specification, drawings, and appended claims.
The invention will be further described by reference to the accompanying drawings which are made a part of this specification.

FIG. 13 is an enlarged view of the structure of this invention similar to that shown in FIG. 9, but indicating the position that the firing pin assumes upon impact of the projectile with an object and the operation of various parts of this invention.
Referring first to the specific form of the invention shown in FIGS. 1 through 6 of the drawings the projectile 11 is formed with a hollow container 12 which is adapted to hold a drug therewithin. The drug, in order to properly operate in this invention, should be in liquid form. A front plate 13 bears threads 14 and gasket 15 and is adapted to be threadedly secured to the forward portion 16 of container 12. Forward portion 16 of container 12 bears mating threads (not shown) on the inner surface thereof.
A hollow needle 17 is disposed upon front plate 13. The cavity 19 of needle 17 communicates with the interior of container 12 through a hole (not shown) within front plate 13. A holding portion 18 is disposed upon needle 17 to prevent needle 17 from slipping out of the body of the animal after impact has occurred.
A stabilizing member 20 is disposed upon the rear portion of container 12. Stabilizing member 20 bears threads 21, gasket 22 and wing portion 23. Threads 21 are adapted to mate with additional threads (not shown) on the inner surface of rear portion 24 of container 12.
A drug propelling member 25 is disposed within container 12 and is adapted to move slidably within said container. Drug propelling member 25 is normally spaced from the forward portion 16 of container 12. A liquid drug 26 is disposed within container 12 forward of drug propelling member 25.
An explosive container 27 is secured to drug propelling member 25 and is preferably behind said member. Explosive container 27 bears offset portions 28 at the rear thereof and a firing pin 29 movable within explosive container 27. A quantity of conventional percussion cap explosive material 30 used in the conventional rifle cartridge (generally a mercuric fulminate composition) is disposed at the forward end 31 of explosive container 27. Percussion cap material 30 is in hardened form so that impact of firing pin 29 will explode said material.
FIG. 6 shows an alternative method of placing the explosive material within explosive container 27. In this construction an auxiliary container 32 is provided and the percussion cap material 30 is disposed within auxiliary container 32. Thus improved assembly of the device can be accomplished.
The assembly of this form of the invention will now be explained.
The container 12 is taken by the assembler and drug propelling member 25 placed within the container at the normal position. A quantity of liquid drug to be used with the projectile is then placed within the forward portion of the projectile ahead of drug propelling member 25. Front plate 13 and its associated parts together with gasket 15 are then threadedly assembled to the forward portion 16 of container 12.
In the operation of this invention the assembled projectile is placed within a gun actuated by gas or by gun- 4: powder and fired at the animal into whose body the drug 26 is desired to be injected. During the time that the projectile is in motion the firing pin 29 is kept back of the explosive material 30. When the projectile hits the animal, however, firing pin 29 moves forward and strikes explosive material 311 with considerable force thereby exploding said material. The force of the explosion moves drug propelling member forwardly and drives the drug contained within container 12 into the animal. The force, however, is not sufiicient to rupture the projectile.
The form of the invention shown in FIGS. 7 through 13 of the drawings will now be described in detail.
The injecting projectile 11a of this form of invention is formed with a hollow body 12a. A drug propelling member 13a is disposed within body 12a and is slidably movable therewithin. Drug propelling member 13a bears ridges 14a which abut the interior surface of body 12a.
Propelling member 13a is further provided with a recess 15 open at the top thereof.
Injecting means comprising a hollow needle 1611, which communicates with the interior of body 12a, projects forwardly from projectile 11a. Needle 16 is secured to front member 17a which in turn is threadedly engaged to body 12a. A barb 18a may further be provided upon needle 16a so that needle 16a may be held in injecting position when it strikes an animal.
A wing member 19a is provided at the opposite end of body 12a and is secured to rear member 20a which in turn is threadedly secured to body portion 12a.
A explosive container 21a is frictionally secured within recess 15a and is open at the top 22a. A pair of overhanging securing portions 23a are provided adjacent top portion 220:.
A secondarily detonatable explosive 2411, such as black powder, is disposed adjacent the closed end 25a of explosive container 21a.
A barrier member 26a is formed with a plurality of openings 27a and presents one face thereof in adjacent relationship with explosive material 24a. A primarily detonatable explosive material 2801, such as mercuric fulminate or other percussion cap material, is disposed adjacent the opposite face of barrier 26a. A firing pin 29a is formed with a body portion 30a and a narrower projecting actuating portion 31a. A coil spring 32a abuts the junction between body portion 311a and actuating portion 31a of firing pin 29a with the actuating portion 31a being within coil spring 32a. Firing pin 29a is slidably movable within explosive container 21a and is normally disposed in spaced relationship with primarily detonatable explosive material 28a. Body portion 30a of firing pin 29a is also disposed in spaced relationship with the adjacent walls of explosive container 21a so that the gases proiuced by the operating explosion will not aifect the par With the foregoing description the operation of this form of invention will now be explained.
The liquid drug 62a, which is to be injected into the animal, is disposed within the forward portion of body portion 12a adjacent needle 1611. Since channel 63a Within needle 16a is relatively small compared to the internal diameter of body 12a of projectile 11a the liquid drug 62a is maintained in position by atmospheric pressure and will not normally leak through channel 63a. Drug propelling member 13a is then disposed above the liquid drug material and explosive container 21a frictionally disposed Within the recess within drug propelling member 13a and projects behind member 13a. The projectile 11a is then placed within firing means such as a gun and fired at the animal. So long as projectile 11a is traveling through the air, the inertial forces involved hold firing pin 29 in the position shown in FIG. 9 and in spaced relationship with primarily detonatable explosive material 28a. When the projectile strikes the animal, on the other hand, the forces involved force firing pin 29a against the tension of spring 32a into impinging relationship with primarily detonatable explosive material 28a as shown in FIG. 13. The detonation of explosive material 28a causes a further detonation of secondarily detonatable explosive material 24a and thus produces a gas which escapes from explosive container 21a in the direction of the arrows shown in FIG. 13. The gas pressure produced then moves drug propelling member 13a forwardly and expels the liquid drug into the body of the animal.
The foregoing specific modifications of the instant invention as shown in the specification herein are for illustrative purposes and for purposes of example only. Various changes and modifications may obviously be made within the spirit and scope of this invention and would occur to those skilled in this art.
