North Brothers Mfg. Company of Philadelphia, Pa., are sending out a neat little pamphlet of a size convenient to carry in the pocket and illustrating and describing Yankee tools. The latter have been named Yankee because they are the invention of a Maine Yankee and because they embody that "ingenuity and slickness in the doing of work for which they are intended which has made Yankee inventions famous the world over." They are simple in construction, strong and durable, do not get out of order, work smoothly and quickly and wear well. The Yankee tools were first offered the trade in 1898, and each year since there has been a notable increase in the sales. The lines include ratchet screw drivers, spiral ratchet screw drivers, chucks, automatic drills, reciprocating drills and pocket magazine screw drivers. In response to frequent demands for the Yankee screw drivers put up in substantial boxes to be used by mechanics who desire to keep the tools in fine order, and by gentlemen or amateur mechanics who especially appreciate tools put up in handsome sets, the manufacturers are offering what is known as the Yankee tool set No. 100. The box contains the styles of Yankee tools most in demand, and the combination in the set covers all the usual requirements in tools for driving in and turning out screws.
