Book excerpt: Excerpt from Appletons' Cyclopedia of Applied Mechanics, Vol. 1 of 2: A Dictionary of Mechanical Engineering and the Mechanical Arts Addressing - machine. An apparatus used for affixing the addresses on a large number of missives, such as newspapers, upon which the same series of names must be inscribed as the day of issue recurs. There are two general forms of this machine. In one the addresses are separately printed on slips of gummed paper, which are fed from the apparatus, which cuts off each address in turn, and allows the latter to remain attached to the wrapper. The other mode is to set up the type of each address in a form, and so to arrange the forms that they are successively presented at a spot to which the enveloped papers are consecutively fed. A large number of these machines have been patented. Adhesion is the molecular attraction exerted between bodies in contact. It occurs between solids and solids, liquids and solids, liquids and liquids, gases and solids, gases and gases, and gases and liquids. The adhesion between two plates of the same material is the same as that between one of the plates and any material which possesses a less adhesive property. Adhesion is supposed to manifest itself at an appreciable distance before actual contact of bodies. The ascent of liquids in capillary tubes is a result of adhesion, as well as the spreading out of liquids between two sur faces kept in close proximity. The chain-pump, in which the water is carried up by a simple chain in a tube, is a practical example of adhesion of liquids to solids. The adhesion of gases and solids is illustrated by the adhesion of air around a piece of solid iron, which causes it to float on melted iron. In the Giffard injecter a blast of steam is used to carry water by its adhesion to it into the boiler against its own pressure. The adhesive force on railroads may be estimated approximately by multiplying the weight of the locomotive in tons which rests on the driving-wheels by a coefficient of adhesion for said wheels. This coefficient is with dry rails 670; very dry rails 560; under ordinary circumstances 450; wet rails 314; in snowy or frosty weather 225. On horse-railroads the coefficient varies from 300 to 400 in snow and frost. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
