FRANK C. BOYNE, OF GRATOII, CALIFORNIA.
Application filedseptember 27, 192? This invention relates to improvements in capsule injectors and has particular reference to a device for injecting capsules into the esophagus of a chicken. r
r The principal object'of this invention is to provide a device wherein a plurality of capsules may be placed in a container and later dispensed individually into the esophagus of a chicken. 1
Another object is to produce a device of this character which is simple in construction and therefore easy to operate;
A further object is to produce a defice which will not clog or crush the delicate capsules. V
A still further object is to produce a de vice which may be used by an unskilled laborer.
Other objects and advantages will be apparent during the course of the following description.
In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same,
Figure 1 is a side elevation of my device,
Figure 2 is an enlarged fragmentary detail view of the injector nozzle, and
Figure 3 is a cross section taken on the line 3-3 of Figure 1. v
In the raising of poultry, particularly chickens, certain epidemics pass through the flock with the result that unless immediate attention is given them many will die.
It is common tofeed capsules to chickens, which capsules are forced down the chickens esophagus in any manner possible. These capsules often enter the windpipe and cause strangulation.
By employing my device capsules may be. fed to the chickens one capsule at a time and with reasonable assurancethatthecapsulewill enter the esophagus instead of the windpipe.
In the accompanying drawings wherein for the purpose. of illustration is shown a preferred embodiment of my invention, the numeral 5, designates a cylinder within which a plurality of smaller pipes 6 are positioned.
The cylinder 5 may have its upper end'closed by a cap 7 held thereon in any convenient manner. A rod 8 extends through the cvl-- inder 5 and has a nut 9 at its upper end which nut is securedto a disc 11 which serves to center the tubes 6. A bottom piece 12 is rotat-' when the bottom piece Serial No. ably held to-the bottom of. the cylinder 5 by a nut 13 which screwsupon the rod 8.
The bottom 14; secured therein in such a manner that- 12 is rotatedlupon the cylinder 5 the discharge spout may I be. brought into registry with any one of the tubes 6 and consequently the contents there of may be discharged into a flexible conduit 16. This flexible conduit is held to an injector by the clamp 17 and to the spout H by a clamp 18. This injector consists of a tubular member 19 having a branch tube member 21. A flexible tip 22is placed upon one end of the tubular member 19 while a slide 23 is movably held in the opposite end of this tubular member. The slide has a head 24 that is slotted as at 26 so as to receive a pin 27 therethrough. This pin serves to limit the movement of the slide. 7
spring 28 surrounds the slide 23 and has one end 29 secured to the slide while its opposite end is secured to the member 19. This slide has its opposite extremity provided with an offset projection 32 having a cam shaped nose 33. A cam surface 3a is also provided upon the slide the purpose of which will be later seen.
Assuming that the tubes 6 have been loaded with capsules and it is desired to treat a flock of chickens, the chicken is grasped in one hand after which the bill is opened and the tip 22 of the injector is placed in the chickens beak, after which the slider is op-' erated by pushing upon the head 24L. The first action of the slide is to contact the first capsule emerging from the branch pipe 21 as for instance the capsule A of Figure 2. This engagement with the capsule will-first allowthe cam end 33 to pass over the capsule and will rock the same to its dotted line position. Further movements of the slide will piece 12has a dischargespout V cause the capsule to become thepusherfor 7 capsule B and assuming that there are one or 7 two capsules in advance of the capsule A, the one nearest the tip 22 will be the one inject ed into the chickens esophagus. lVhen the pressure is relieved from the head 24, the
slider back to its sule A isreleasedit will move forward and take the position B while a new capsule will fall by gravity to the position A.
During the movement of the slider the cam surface 34 will have contact with the end of the capsule C and will have prevented the moving into A, position, at the same time preventing any danger of crushing the capsule.
It is to be understood that the form of my invention herewith shown and described is to be taken asa preferred example of the same and that various changes relative to the material, size, shape and arrangement of parts may be resorted to without departing from the spirit of the iIlYQll'tiOll or the scope of the 'sub'joined claims.
Having thus described my invention, I claim:
1. In a device of the character described, a cylindrical member adapted to receivea plu rality of capsules, a flexible pipe extending from said cylinder, an injector secured to said flexible ipe, a slider movable in said injector and ac apted to discharge capsules one at a time therefrom, said capsules entering said injector from said flexible pipe in the manner described. a
2. In a device of the character described, a cylindrical member having a rotatable bottom thereon, a plurality of tubes secured in said cylinder and adapted to have the lower extremities brought into successive registry with a spout formed in said bottom, a flexible pipe secured to said spout, an injector secured to said pipe and means for discharging the capsules from said injector one at a time.
In a device of the character described, an injector including a tubular portion and having an offset tubular portion secured thereto, a slider movable in said tubular portion, spring means for normally maintaining said slider in extended position, an offset formed on said slider, a cammed tip formed on said offset and a cam surface formed on said slider for the purpose specified.
In testimony whereof I affix my signature.
