UNITED STATES PAUL STADLER, OF CHICAGO, ILLINOIS.

INJECTION INSTRUMENT.

Application filed March as, 1925. Serial in. 17,848.

To all whom it may concern:

Be it known that I, PAUL STADLER, a citizen of Germany, residing at 312 E. 31st Street, Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Injection Instruments, of which the following is a specification.

This invention relates to new and useful improvements in injection instruments and more particularly to a device of this character which is adapted to be projected through the air. The main object of my invention is the provision of an injection instrument adapted to be projected through the air and when brought into contact with an animal or similar object will penetrate the skin and inject a fluid into the system of the animal for rendering them temporarily unconscious.

Another object of my invention is an instrument of the above character which is so arranged that when the instrument strikes the body of an animal the penetrating prongs will be automatically released for engagement with the body of the animal and adapted to penetrate beneath the skin and at the same time releasing an injection fluid which may be passed into the system of the animal through the penetrating prongs.

With the above and other objects in View, In invention consists in the novel features of construction and the combination and arrangement of parts to be hereinafter more fully described, pointed out in the claims and shown in the accompanying drawings, in which:

Fig. 1 is an elevation, parts thereof being broken awayand illustrated in section.

Fig. 2 is a'longitudinal sectional View.

Fig. 3 is an elevation showing the use of the device.

Fig. 4 is a detail section dn the line 4-4 of Fig. 1.

In carrying out my invention I provide a casing 1 having a removable cover 2 and a socket 3 at one end adapted to receive the stem 4 which has on its outer end a recessed head 5 adapted to engage with the string of a bow or similar instrument for projecting the casing 1 through the air.

The casing in the present instance is oval shaped in form and provided with an opening 6 at the end opposite the socket 3 through which the reciprocating arm 7 extends and which is provided with a striking head 8 at its outer end. This arm 7 is preferably arranged centrally of the casing adjacent I the back wall thereof and formed integral with the casing upon opposite sides of the arm 7 are the spaced ears 9 supporting the bolt 10 upon which are mountedfor rocking movement the arcuate shaped penetrating prongs 11 having points 12 at their outer ends. These prongs 11' are provided with a central duct 13 which communicate with the threaded nipple 14 at the inner ends of the prongs and to which are attached the connecting tubes 15 formed of flexiblematerial. The inner ends of the prongs 11 are mounted in the transverse openings 16 formed transversely in the enlarged central portions 17 of the bolts 10 and retained in this position by means of the nuts 18 which are threaded onto the nipple 14.

The bolts 10 areprovided with rectangular portions 19 upon which are mounted the trigger arms 20 which are arranged within the casing 1 and have hooks 21 at their inner ends for engagement with the catches 22 carried by the arm 7. The trigger arms 20 have attached thereto suitable springs 23, said springs being connected to the interior wall of the casing 1 as at 24 for actuating said trigger arms when released from the catches 22.

The trigger arms 20 carry the headed pins 25 which move in the arcuate slots 26 formed in one wall of the casing 1 for guiding the trigger arms in their movement.

From the above it will be apparent that when the device is projected through the air and the head 8 comes in contact with the I animal as shown in Fig. 3, the arm 7 may be forced inwardly against the tension of the spring 27, disengaging the 'ca tches 22 from the hook members 21 so that the tension of the coil springs 23 will rock the trigger arms 20 rotating the bolts 10 and thus move the penetrating prongs 12 toward each other so that they engage and penetrate the body of the animal as shownin Fig. 3. When this operation takes place the liquid is discharged through the duct 13 into the system of the animal, the liquid being automatically discharged as will be now fully set forth.

The tubes 15 are connected to the cross pieces 28 of the funnel 29, said funnel having extending into its upper end a pipe 30 which leads from the supply receptacle 31 which contains the fluid for injection into the animal.

.may be readily adjusted by means of the nut 37 carried by the sleeve 34 and engaged with the guide 35.

The end of the guide 35 opposite that which is mounted upon the sleeve 34 is mounted upo n the threaded sleeve 38 and also has an opening 39 to receive the" guide rod 40 to prevent any turning movement of the guide 35 relative to the sleeves 34 and WVhen the arm 7 is reciprocated against the tension of the spring 27 the valve 41 which controls the outlet of fluid from the receptacle 31 is actuated by means of the pin 42 which is carried by the arm and en- "ages the handle 43 on the valve 41 as is illustrated in Fig. 2. This movement opens the valve 41 and .allows some of the liquid from the receptacle 31 to pass downwardly through the ducts 13 and into the system of the animal when the prongs 11 have penetrated the body of the animal as shown in Fig. 3.

It will be understood that the liquid used in connection with this device is preferably of such type as will render the animal temporarily unconscious so that this device will be extremely valuable in use for catching animals where it is desired that they be notinjured and are especially caught for captivity. It will be noted that this device will also be extremely useful in catching wild animals for captivity for zoological parks and the like.

While I have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction and in the proportions may be resorted to for successively carryin my invention into practice without sacrificing any of the novel features or departing from the scope of the appended claims.

Having thus described my invention, what I claim is:

1. A device ofthe character described including a supporting body, a reciprocating arm, movable penetrating prongs upon each side thereof, means carried-by the arm for normally retaining said pron s in a separated position, means actuated by'said arm when the arm engages an object for releasing said prongs and additional means for moving said rongs toward each other upon the re case 0 the retaining means.

moving said prongs toward each other upon I the release of the retaining means, said prongs having a duct therethrough and means automatically operated through the movement of said arms upon releasing said prongs for supplying a fluid to said ducts.

3. A device of thecharacter described including a carrying body, a reciprocating arm supported thereby, catch members carried by said arm, penetrating prongs pivotally mounted upon the body upon opposite sides of the arm, said pron s each having a duct therethrough, means fiaving operative connection with the prongs and engaging said catch members for normally retaining said prongs in a spreading position, said catches being released upon the movement of the arm in one direction, spring members carried by the .body, cooperating with the prongs for moving them toward each other upon being released and means automatically operated through'the movement of said arms for releasing the prongs to'supply a fluid to said ducts.

4. A device of the character described including a carrying body, a reciprocating arm supported thereby, pivoted prongs on the body upon opposite sides of the arm, cooperative means between the prongs and arm for operatively retaining the prongs in a spreading position, said means being released upon the movement of the arm in one direction and spreading members having connections between the body and said prongs whereby to move the prongs toward each other upon the release of the retaining means.

5. A device of the character described including a reciprocating arm, pivoted penetrating prongs upon each side thereof, cooperative means between the prongs and arm for retaining the prongs in a spreading position, said means being released upon the movement of the arms in one direction, means for moving said prongs toward each other upon the release of the retaining means, said prongs having ducts therethrough, a liquid supply chamber adjacent the arm, means forming communication between the supply chamber and ducts and means for automatically releasing a supply oi the liquid to said ducts upon the movement of the arm for releasing said prongs.

in testimony whereof I atfix my signature.

PAUL STADLEB.
