Abstract
Abstract An electrically powered vaccinator operated by a body member of the bird or animal being vaccinated, usually the wing or leg of a chicken, which is manually brought into slight pressure contact with a plate operating a power-controlling switch, so that a vaccine applicator of needle or spray type is actuated at the instant that the body member is in optimum position for injection or spraying. The switch and contact plate assembly is shiftably mounted for multiple uses and the dosage and/or penetration of the body member is adjustable.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
143 words
A frame having a wall portion (12) with a syringe seat plate (28) and coacting wing plates (18); a multiple dose syringe mounted on said seat plate and having finger pieces (16) clamped in place by said wing plates, said syringe having a vaccine applicator element and a plunger operatively mounted in a vaccine-receiving cylinder; an electromechanical actuator for said syringe operatively mounted on said frame; a switch connected to control the functioning of said actuator; and a pressure plate operatively mounted adjacent said vaccine applicator and accessible for pressure contact by a body member of the animal or bird vaccinated to close said switch anD actuate the plunger of the syringe only upon a predetermined movement of said pressure plate corresponding timewise to a predetermined optimal positioning at the instant of maximum penetration of said body member by said vaccine applicator needle.
