CAPSULE rononrs.

Application filed February 20, 1928. Serial No. 255,747.

The invention relates to an improved form of instrument adapted to be used for administering capsules to animals.

In feeding capsules to animals it is necessary that the capsule be inserted well back in the throat to insure swallowing, and except in the case of small animals the insertion of the capsule must be made with instruments to avoid danger of being bitten. The object of the invention is to provide an instrument constructed in such a manner that it is inexpensive to manufacture, capable of being used efliciently with various sizes of capsules, capable of being easily manipulated and quickly operated to release the capsule.

In order to attain the objects above enumerated, I have provided the novel forceps construction hereinafter more fully described and illustrated in the accompanying drawings, wherein Figure 1 is a plan view of the improved instrument;

Figure 2 is a side view thereof;

Figure 3 is a cross section on the line 33 of Figure 1;

Figure 4 is a similar section on the line 4-4 of Figure 1;

Figure 5 illustrates the use of the instrument in feeding capsules to animals;

Figure 6 is a section on the line 66 of Figure 2.

Referring now to the construction illustrated in the drawings, the improved instrument is preferably made from a single piece of pressed sheet metal which is fashioned into the desired configuration. The arms A and B are integrally connected by the U- shape bend C and extend outwardly therefrom in substantially a straight line for the greater part of their length. At the free ends the arms are laterally curved as indicated at D forming the slightly enlarged end portions E. The arms A and B normally diverge slightly from each other as indicated in Figure 1 so that the end portions E are spaced apart for a distance greater than the width of the largest capsule they are adapted to grip.

Adjacent the U-shape bend C the arms are preferably fiat as indicated at F and of uniform width for suflicient distance to form a handle. If desired the outer surfaces of both arms A and B may be loosened slightly as indicated at G to provide a better gripping surface. The arms are diminished in width beyond the loosened portion G and are also dished so that the outer surfaces are slightly rounded as indicated at H. Thus the inner surfaces I of the arms are transversely curved as indicated in Figure 3 and this hollow curved portion extends to the outer extremity of each arm. At the end portions E the metal is more deeply pressed out forming the concavities J which are adapted for receiving the rounded surface of the capsule.

Referring to Figure 5 it will be noted that a capsule is being gripped by the forceps and the operator is about to insert the capsule into the throat of the animal. The arms A and B are sufficiently long so that the concave ends of the instrument can be inserted well back in the throat and the capsule may be firmly gripped by the instrument to securely hold the same in the instrument. When the capsule is inserted to the desired point in the throat it is quickly released by merely releasing the manual pressure upon the arms A and B whereupon they spring outwardly and permit the capsuleto drop.

The instrument constructed as above described is of great practical value in administering capsules to animals and it is easier to operate and cheaper to manufacture than any other instrument heretofore constructed for the same general purpose.

The type of capsule ordinarily used with the instrument is a soluble elastic capsule which due to its flexible nature is adapted to be gripped by the concave ends and firmly held by the instrument. However, the instrument is not limited in its use for the gripping of this particular type of capsule but can be used with other types of capsules, pills, tablets, boluses, medicine balls and may also be useful for other purposes.

hat I claim as my invention is:

1. A capsule feeding instrument comprising a pair of normally diverging spring arms integrally connected by a return bent portion, said arms being dished to form longitudinally extending channels, the ends of said arms being enlarged in width and pressed out to a greater depth forming capsule gripping concavities adapted to conform to a flexible capsule.

2. A capsule feeding instrument comprising a pair of normally diverging spring arms integrally connected by a return bent portion, said arms being provided with a longitudinilly curved tip portion, said tip portion being dished outwardly to form a rounded inner surface for engaging a cap sule.

3. A capsule feeding instrument comprising a pair of integrally connected spring arms each having a flat handle portion, a longitudinally dished portion extending in alignment with said handle portion and having the free end portions laterally bent and enlarged in Width, said free end portions being also dished to form a concave inner suriace for gripping the capsule.

4. A capsule feeding instrument comprising a pair of integrally connected sheet metal arms of rectangular cross section for a predetermined distance forming a handle portion, said arms being of lesser Width ,beyond said handle portions and extending in substantial alignment therewith, the outer ends of said arms being curved laterally, said outer ends being dished to form longitudinal channels and the tips of said arms being enlarged in Width and provided with concave inner surfaces for engaging a capsule.
