ABSTRACT:
An injection apparatus that is particularly suitable for accurate and precise injection of eggs of varying sizes and that may be presented to the injection apparatus in somewhat different orientations. The injection apparatus comprises a generally horizontally oriented tooling plate with an opening therethrough, an injector resting generally vertically in the opening in the tooling plate with a lower portion of the injector depending downwardly below the tooling plate and an upper portion of the injector resting at or above the tooling plate. Means are included for raising and lowering the tooling plate and the injector therewith so that when the plate is lowered and the lower portion of the resting injector strikes an egg to be injected, the resting injector stops while the tooling plate proceeds downwardly until the injector disengages from the tooling plate and is free to move in a translational direction independent of said tooling plate. When the tooling plate is raised it reengages the injector and carries it upwardly and away from the egg.
