Automatic machine for peeling hard-boiled eggs
First Claim
1. An automatic machine for peeling hard-boiled eggs comprising(A) a carrier frame;
- (B) a plurality of hard-boiled egg receiver cups, each of said cups having an inlet orifice and a bottom defining a constricted circular opening whose diameter is slightly less than that of the largest diameter egg;
(C) a source of compressed fluid;
(D) a movable stand carrying said cups;
(E) drive means for driving said stand;
(F) a feeding station provided with dispenser means for delivering a hard-boiled egg to one of said cups presented thereto;
(G) break means for breaking the shell of the egg at each end thereof;
(H) shattering means operatively connected to said source of compressed fluid for injecting said compressed fluid under pressure inside the shell between the membrane and the white of the egg to shatter the shell;
(I) ejection means operatively connected to said source of compressed fluid for hermetically sealing off the inlet orifice of said cup and putting the interior thereof under sufficient pressure to drive the white of the egg out of its shattered shell through said constricted circular opening of said cup, and(J) a cleaning station provided with cleaner means for driving the shattered shell out of said cup.

Abstract
The invention relates to an automatic machine for peeling hard-boiled eggs.
The machine comprises a frame 3, a rotating stand comprising a plate 14 mounted at an end of a vertical shaft 7 rotating in a bearing 4, hard-boiled egg receiver cups 17 suspended around said plate 14, a chute 26 for conveying hard-boiled eggs, an upper carrier plate 26 for a return jack 21 and sleeves 27 distributed at the periphery of said plate and through which a series of vertically displaceable tools may slide, and a return plate 23 fixed at the end of the rod 22 of the jack 21 and adapted to control the displacement of the tools which are urged in the direction of the stand by compression springs.
Application in the automatic peeling of hard-boiled eggs on the industrial scale.
