typesetting (tipset"ing)

The act or proce of setting or combining types in proper order for printing. It is usually done by picking up each type from an exposed case, and arranging the types so collected in a composing-stick in lines of even length.Type-setting machine, a mechanism intended to quicken the operation of type-setting. In the simpler forms of mechanical type-setters, the types, separately arranged in inclined tubes or channels, are succe ively dislodged by the pre ure of appropriate levers moved by the fingers of the operator on a keyboard. As the types fall, they are collected in a long line, and afterward subdivided in lines of proper length. The Kas ten be in and McMillen machines are of this construction. Distribution of types is usually done by a separate machine, of which there are many varieties. In all, each distinct letter or character is provided with its own special nick, which serves the IMG:content-1192.png:[merged small][merged small][merged small][merged small][merged small][merged small][merged small][ocr errors][merged small] a, distributing-cylinder; 6, setting-cylinder; c, mechanism actuating distributing-cylinder; d, driving mechanism actuating type-car rying disk, carrying-belt, packer, keyboard, levers, etc.; e, shaft, which transmits the power to all parts excepting the distributing-cyl. inder; type-carrying disk; g, packer, which lifts the type singly into a continuous line; A, keyboard; 1, levers, connecting keyboard with bottom of setting-cylinder; 1, copy-holder: 4, justifying mechanism; 4, iron case for spaces and hyphens; m, type-bank, containing italics, which are inserted by hand as required; ", case for small capitals, in some machines for fractions and other odd characters, to put in by hand. same purpose as the nicks or channels in a key for the wards of its lock.

The first type-setting and type-making machine was planned at London by Dr. Church in 1824. More than fifty varieties of machine type-setters have been invented, but few are in use.
