*********************************************************

At the Great Seal Patent office on the seventeenth day of October, 1868, a patent was sealed for Mr. Amos Holbrook, jun., of Lynn, in the county of Essex, and state of Massachusetts, United States of America. The patent sealed was dated the 11th of May, 1868. The nature of Mr. Holbrook's invention consists in combining with a series of sewing needles actuating mechanical devices in such a manner that if “signatures” of a book be passed to the machine while the same is in operation they will be taken and carried into the machine, properly adjusted and securely sewed to each other. The several movements and their actuating devices are of a complicated nature, but they will perhaps be properly understood by the illustrations we publish, with an abstract of the sealed specification.
