The-present invention relates to capsule guns and has for an important object thereof the provision of a gun adapted for use in forcing capsules or the like down the throat 5 of an animal.

Another object of this invention is to provide a gun of this character which is provided with a substantially elongated barrelfor removablyreceiving aV capsule, the capsule being ejected from the barrel after the barrel has been forced into the throat of the animal.

A further object of this invention is to provide a reciprocable ejector for ejecting a capsule from the chamber ofthegun. A still'further object -of this invention is to provide in a gun of this character a hollow handle Vwhich is adapted to be used asa reser- 10 un. f The above and various other objects and advantages of this invention will in part be described in and in part be understood from the. following detailed description of the present preferred embodiment, the samebeing illustrated in the accompanying drawing wherein Figure 1 is a longitudinal section, partly in detail, of a device constructed according to the preferred embodiment of this invention; Vand v v Figure 2 is a fragmentary transverse section taken on the line 2 2 4of Figure 1.

Referring to the drawing wherein. like,

numerals of reference designate corresponding parts throughout the several views, the num-eral 10 designates a hollow handle of suitable dimensions which is so constructed as to be easily positioned in the hand, the

40 periphery of the handle being preferably knurled or otherwise roughened as at 11.`

An elongated barrel 12 is mounted on the outer end portion of the handle 10 and is angularly inclined therefrom. The'barrel 12 is provided at the outer'end portion thereof with a capsule receiving member 13. An ejector 14 is reciprocably mounted in the barrel 12 and provided at the inner end portion thereof with a threaded portion 15 for threadably receiving a thumb or nger enf A cup-shaped annular member 19! isiylsecuredto the outer restricted end portion AofV voir or chamber for holding capsules for. the

Y*

In the operation of this device, one of the '5(5- j capsules 20 may be removed from the handle 10 and placed in the ejecting chamber 13,the capsule being relatively flexible so thatit vwill engage the inner peripheryof the ejecting chamber and be securely held therein by reason of its own flexibility. The capsule securing member 13 may then be placed in the throat of the animal, being forced downwardly thereinto a sufficient distance so that capsule. The reciprocable ejector 14 may then be forced outwardly by pressing .the thumb or other member of they hand against the annular member 16,'Whereupon the capsule engaging member Will force-the capsule 2O outwardly of the capsule chamber 18 and l being restricted only I vals;

into the throat of the animal. It is, of course,

' to be understood that the capsule 20-may contain any desired medicinewhich itis desired to place'in the throat of the animal, and the exterior of the capsule is 'preferably' constructed of the conventional gelatine rna-.VVVV

Y c ItV will, of course, be understood that va-V Y `rions changes and modifications may be made in ther details of construction and design of the above vspecifically describedembodiment of the invention Without departing from the spirit thereof, such changes and modifications j by the scope of the following claim.
