Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
225 words
A device for automatically and continuously stamping eggs with an indicia to form a basis for judging the freshness of the eggs comprising in combination: an intermittently moving conveyor means longitudinally extending in the horizontal plane whereby the vicinity of one end of said longitudinally extending conveyor means constitutes an egg stamping area; means for intermittently feeding eggs on an individual basis to said egg stamping area; an elongated frame member positioned longitudinally and in a substantial parallel manner adjacent to said conveyor means; a plurality of arm members fixedly supported at spaced intervals on said elongated frame member, each of said arm members arranged substantially at a right angle to said elongated member and having base and tip portions, the base portion being slidably associated with said conveyor means and the tip portion having an arcuate configuration to define a spoon-shaped section, said spoonshaped section operatively propelling an individual egg from said egg stamping area; two rail members disposed substantially parallel to said conveyor means; a lever member slidably supported between said two rail members and including a downturned tongue portion, said downturned tongue portion terminating in said egg stamping area and having an opening therethrough; and a spring pressed stamper member resiliently mounted within said opening and operatively stamping individual eggs intermittently being transferred to said stamping area by said intermittently feeding means.

Dependent Claim
16 words
A device as defined in claim 1 wherein said conveyor means is an endless chain conveyor.
Claim 4
Dependent Claim
38 words
A device as defined in claim 1 wherein said intermittently feeding means includes additional conveyor means and a pair of transfer rail means bridging the transfer of eggs from said additional conveyor means to said first-mentioned conveyor means.
