Abstract
Abstract An egg packer with the eggs picked up from a slotted conveyor by a conveyor of rollers having pockets formed between each of the rollers and an adjacent parallel rod, carried up an incline while being rolled and travelling toward its small end, and contacting a guide tongue as it goes over the top of the roller conveyor which guide retards the large end of the egg causing it to pass point down into a retainer for transfer to a clam-shell transfer means which shuttles the egg between the retainer and a receiving pocket therebelow, while adjusting the horizontal spacing between eggs during their descent to the receiving pockets.
