Abstract
Abstract An improved breaker head is disclosed for use on automatic egg breaking machines. These machines receive whole eggs from a conveyor or other egg feeder and crack, open and drain the eggs. This improved head has a cracking knife arrangement which engages the inner side portions of the egg shells. This facilitates egg drainage by permitting a more complete and a more rapid draining of the egg white, facilitates the yolk removal, and adjusts knife penetration in accordance with the egg size to protect yolks from knife damage in smaller eggs.

Claim 1
Independent Claim
146 words
In an egg cracking head for an egg breaking machine having a pair of egg supports including outer egg holding end portions and means for pivotally attaching said supports for hinged movement and with an egg cracking knife pivotally attached to each support at facing edges thereof and having a generally straight cracking edge the improvement comprising means for positioning said knives for movement between a first cocking position spaced from an egg held in said end portions and a second egg cracking position with the said cracking edges of the knives penetrating the egg and extending inwardly and upwardly from a point adjacent to where a vertical center line crosses the bottom of the egg shell and with said cracking edges being positioned at an acute angle to the said center line whereby a lowermost portion of the cracked egg shell is exposed for drainage.
Claim 2
Dependent Claim
146 words
In an egg cracking head for an egg breaking machine having a pair of egg supports including outer egg holding end portions and means for pivotally attaching said supports for hinged movement and with an egg cracking knife pivotally attached to each support at facing edges thereof and having a generally straight cracking edge the improvement comprising means for positioning said knives for movement between a first cocking position spaced from an egg held in said end portions and a second egg cracking position with the said cracking edges of the knives penetrating the egg and extending inwardly and upwardly from a point adjacent to where a vertical center line crosses the bottom of the egg shell and with said cracking edges being positioned at an acute angle to the said center line whereby a lowermost portion of the cracked egg shell is exposed for drainage.
Claim 3
Dependent Claim
182 words
In an egg breaking machine having a plurality of egg breaking heads mounted on a carrier for movement around a generally horizontal and at least partially closed path with the egg breaking heads each having a pair of egg supports including outer egg holding end portions and means for pivotally attaching said supports for hinged movement and with an egg cracking knife pivotally attached to each support at facing edges thereof and having a generally straight cracking edge the improvement comprising means for positioning said knives for movement between a first cocking position spaced from an egg held in said end portions and a second egg cracking position with the cracking edges of the knives penetrating the egg and extending inwardly of said supports and said path and upwardly from the bottom portion of the egg from a point adjacent to where a vertical center line crosses the bottom of the egg shell and with said cracking edges being positioned at an acute angle to the said center line whereby a lowermost portion of the cracked egg shell is exposed for drainage.
