  • Patent number: 4019513
    Abstract: Automated apparatus for shaping the beaks of young fowl and simultaneously giving them an oral injection. A backing member is mounted for generally horizontal arcuate movement and a red-hot blade is mounted for generally vertical arcuate movement. The upper half of the fowl's beak is put on the top of the backing member which is urged forward by force exerted on the fowl's body. A pneumatic circuit is controlled by this forward movement and actuates a pneumatic jack which moves the blade downward clamping and cutting the fowl's beak at least partially. With the downward movement of the blade an injection gun may be triggered and compressed air injects a vaccine into the fowl's oral cavity through suitable apertures in the backing member. Compressed air is also carried through the backing member to blow away severed bits of beak. After a predetermined interval the pneumatic circuit returns the blade to its initial position.
