PILL INJECTOR.
APPLICATION FILED AUG-B. ISIS.

.IINED SATES PATENT O FIQE.
GEORGE F. ANDREWS, OF HOMINY, OKLAHOMA.
v PILL-INJECTOR.
Application filed August 8, 1916.
To all whom it may concern:
Be it known that I, Gnonen F. ANDREWS, a citizen of the United States of America, residing at Hominy, in the county of Osage and State of Oklahoma, have invented certain new and useful Improvements in Pill- Injectors, of which the following is a specification.
This invention relates to an injector for inserting pills beneath the hides of young cattle and it has for its object the provision of an improved device of this character constructed in such manner that one pill at a time may be fed from a magazine into a hollow needle and there held securely against accidental dropping during the time that the operator is inserting the needle preparatory to ejecting the pill therefrom.
Further objects and advantages of the invention will be set forth in the detailed de scription which now follows.
In the accompanying drawing Figure 1 illustrates the invention partly in side elevation and partly in section, and
Fig. 2 is a horizontal sectional view of the device on line XX of Fig. 1 and Fig. 3 is a detail sectional View upon an enlarged scale through the magazine and associated parts with the plunger at its lowermost limit of movement.
Like numerals designate corresponding parts in the figures of the drawing.
Referring to the drawing the numeral 5 designates a casing the forward end of which is closed by a cap 6. This casing is provided in its side with an elongated slot 7 and a transverse slot 8, said transverse slot being disposed adjacent the lower end of the slot 7 and communicating with the slot 7. A thumb piece 9 is connected by a shank 10 with a plunger 11, the latter being disposed centrally within the receptacle 5. A spring 12 surrounds the lower portion of the plunger 11 and bears between shank 10 and the bottom of the casing 5. This spring normally tends to force the plunger 11 outwardly. The forward portion of the lunger is disposed within a barrel 13 which orms a continuation of and is in communication with a hollow needle 14:. A magazine 15 receives the pills and this magazine may be provided with a removable cap 16. The lower end 17 of the magazine is directed transversely and communicates with the barrel 13. The arts are so proportioned that wh n the h m pie e 9 is d awn inwardly Specification of Letters Patent.
Patented Apr. 1c, 1918.
Serial No. 113,824.
to enter the barrel in advance of the plunger.. The plunger is then permitted to move outwardly a slight distance or until the shank 10 may be moved into slot 8. This slight outward movement of the plunger covers the mouth of the magazine and prevents more than one pill entering the barrel 13 at one time.
Since calves and young cattle frequently ofi'er considerable resistance to the injection of the pills used for the prevention of blackleg, it is highly desirable to provide a structure which will hold the pill safely a ainst loss during the time that the needle is loeing inserted beneath the hide of the animal.
Heretofore it has been necessary to employ an assistant to aid in holding the animal while the pill is being injected. With the present device this will not be necessary because the instrument will safely hold the pill during the struggles of the animal and tmtil the needle has been satisfactorily inserted, after which the thumb piece is moved laterally to release its shank 10 from slot 8 and said thumb piecethen moves outwardly in slot 7 and the plunger 11 ejects the pill from needle 14 in a manner that will be readily understood.
It is to be understood that the invention is not limited to the precise construction set forth but that it includes within its purview such changes as fairly come within the spirit as well as the exact terms of the appended claims.
Having described my invention what 'I claim is 1. A device of the character described comprising a'pill magazine, a hollow needle with which said magazine communicates and a plunger mounted to reciprocate in longitudinal slot, a plunger within the body, a thumb piece movableuponth'e'exteriorof the body and a shank connecting the plunger and thumb piece, a spring surrounding'the inner portion of the plunger and normally tending to force the plunger outwardly, a hollow needle carried by th'e'body in which said plunger is slidably disposed and a magazine havinga mouth communicating with thehollow needle and across the mouth of which said plunger moves, :the relative sproportions of'theparts being such that when the shank of the thumb piece is at its inward limit or =movement said plunger uncovers the mouth of the magazine and when said 15 shank'isdisposed in the transverse slot said plunger covers the mouth of the magazine. Intestim'ony whereof I aflix mysignature in presence of'two witnesses.
