MACHINE THAT TESTS EGGS.
A machine that automatically picks out bad eggs, and grades others according to their weight, was shown in operation at a London dairy depot Streatham, recently. The machine, which resembles a model switchback, consists almost entirely of parallel sets of toy railway lines, set on a gradient down which the eggs roll by gravitation. ,' In their' descent they pass over a series of tilting balances, which pick out automatically those that correspond with the standard weights at which balances are set. The eggs thus derailed are tipped into miniature lifts, and pass, one at a time, to further sets of rails, when they roll into a compartment, ready to be packed in crates. If the eggs are stale they fail to take the first ascent in the switchback, roll backwards, and are tilted out of •the way for rejection by the packers. This automatic rejection is due to the fact that as an egg loses its freshness the yolk gradually drops iuside the shell, and alters the weight and balance. ?
