History of the Typewriter

—199— segment having an assembling surface of four inches. In addition, the wide hanger, which is made possible, enables us to assemble them in such a way that every third hanger is placed on top, so that we gain four inches in this manner, giving us an entire assembling surface of sixteen and a half inches. This makes possible the use of a heavy type- bar with a pivotal bearing seven-sixteenths of an inch wide, and gives us an adjustable bar so that wear, as it occurs, can be ‘ taken up ’ simply by turning a screw, and the alignment retained during the entire life of the typewriter. “ We have in this construction united the durability of the type-basket machines with perfect visible writing.” The key tension is only two and a half ounces. That means it requires only two and a half ounces of expended force to print a letter. The ribbon movement permits either the single colour or the two-colour ribbon to be used. The action of the ribbon is entirely automatic, the reverse movements being absolutely positive and accurate, and requiring no attention from the operator. When a single colour ribbon is used, the ribbon oscillates, which means that its entire surface is used ; a feature which effects a wonderful saving in the cost of typewriter ribbons. One of the arguments against a typewriter equipped with a narrow ribbon in the past, has been that the ribbon wore out too easily on account of its limited surface. The movement above described practically doubles the life of a ribbon. When a two-colour ribbon is used, the colour is changed by touching either the red or the black button, which is situated at the left of the keyboard, when the desired colour is instantly thrown into position ; a great advantage for all kinds of work where two-colour effects are desired. The carriage is ball bearing, is operated with a tension of only one pound, which means that the force required to return the carriage to begin a new line is much less than is the case with many other writers. The carriage is interchangeable, so that the regular models can be quickly changed into long carriage machines, doing away with the necessity of buying a special long carriage machine where the work requires the long carriage. This is a distinct advantage and a great saving. The line spacing is automatic. The carriage is returned to begin a new line by means of the line space lever. The one movement returns the carriage and spaces for the
