1. An injection apparatus that is particularly suitable for accurate and precise injection of eggs to the same depth and location when the eggs are of varying sizes and may be presented to the injection apparatus in somewhat different orientations, said injection apparatus comprising:

  • a generally horizontally oriented tooling plate with an opening therethrough;

    an injector resting generally vertically in said opening in said tooling plate with a lower portion of said injector depending downwardly below said tooling plate and an upper portion of said injector resting at or above said tooling plate; and

    means for raising and lowering said tooling plate and said injector therewith so that when said plate is lowered and said lower portion of said resting injector contacts an object such as an egg to be injected, said resting injector stops while said tooling plate proceeds downwardly until said injector disengages from said tooling plate and is free to move in a translational direction independent of said tooling plate, and so that when said tooling plate is raised it reengages said injector and carries it upwardly and away from the object being injected.
