IOO INTERNATIONAL EXHIBITION, 1876. and, the moment the pressure ceases, the machine comes to an instan taneous stop. One of these spooling-machines will wind one hundred and ten dozen of spools a day; and some conception of the extent of the Nonotuck Company’s business may be gained from the fact that they have no less than sixty of these spooling-machines in constant operation in their factory, where they employ over six hundred hands. Only one thing has to be done to render the spools ready for the silk; it is to stamp their two ends with the brand and the name of the company. This is done by.one of the prettiest and most perfect little pieces of machinery in the hall, and the stamping of the colors into the wood obviates the falling off of printed labels, as is sometimes the case with cotton spools from insufficient gumming in the labeling- machine. The spools are fed from a trough, through a hollow post, into the stamping-machine; an arm pushing them one by one, as they come out at the base of the post, into a groove, where they are caught and held in position by a small weight, the spool at the same time pushing back a spring. Two spools are in the grooves at one time, the one receiving its first and the other its second stamping simulta neously. At either end of the spools are two dies, one inked with red and the other with blue ink. These dies press upon the spools simul taneously, impressing the name of the company in one color, and, on the second impression, the brand in the other color. The outer spool is then released by the momentary rising of the weight, and the spring against which it was pressing kicks it out into a basket. The groove- bed revolves, bringing the inner spool to the outside and a new spool into the place of the inner one; the operation being repeated ad in finitum. As the dies spring back from the spools, they take a quarter turn upward, which brings them under the inking-rollers; the rollers being inked and moving in a similar manner to those in a job-printing press. There are four composition rollers to each ink reservoir, and pair of dies. The whole stamping-machine is divided into two parts, each the counterpart of the other, and turns out the stamped spools at the rate of one hundred and twenty a minute. One machine will stamp seventy thousand to eighty thousand spools a day, sufficient to fill ten ordinary flour-barrels. When wound on the spools, the silk is ready for the completion of orders, or to go into stock in the warehouse.” The Fabrication of Spun Silk.—It was in the silk-culture that the largest and most celebrated of our manufactories of silk goods, that of the Cheney Brothers, had its birth. As this establishment is wholly without rivals in its special department, and one of the most characteristic in the whole range of the American textile industry,
