It w^as at first intended that the subject of Machine-Printing only should be treated of, but, after con- sideration, it was decided to include descriptions of the details and principal points of construction of all classes of typographic printing-machines. When an apprentice is first put to machine, from press, it is as necessary that he should be acquainted with the mechanical movements of a machine, as to know how to patch a sheet or overlay a cut ; for a workman who has studied the construction of the machine which he has been trusted to manage will seldom, if ever, be without resources should an unforeseen difficulty arise. In the following pages, therefore, the different working parts and peculiar merits of bookwork and newspaper machines have been briefly described and illustrated by diagrams. In treating of those matters which relate to the general management of machines, this manual does not pretend to teach a trade w^hich can be acquired only by practical experience ; it simply gives the general principles of Making Ready, which it is hoped will prove useful to the inexperi- enced, and points out the peculiarities of the machinery employed. Many workmen are trained in offices where but one or two machines are in use, and these perhaps vi PRINTING-MACHINES AND MACHINE-PRINTING. of the old-fashioned kind ; they may, therefore, have lacked the opportunity of becoming acquainted with more modern and perfect inventions. To such, the following pages, in giving an idea of the improvements that have been intro- duced, will be of especial interest. The work for which each class of machine is suited having been generally indicated, this Handbook may be useful as a guide to intending purchasers, who, however, will of course form their own opinion of the workmanship and the comparative merits of rival machines. The important subject of Motive Power could not be treatise like accordingly there omitted in a the present ; will be found a short account of the various forms of steam and gas engines and other motors now employed in the printing business. A few remarks have also been offered upon the management and economy of the Warehouse, and the names and descriptions of various approved appliances mostly in use in that important department of a printing- office have been given. To the Editor of the Printing Times and Lithographer^— in which publication much of the matter contained in these pages originally appeared,—the author must acknowledge his indebtedness for valuable assistance throughout the progress of this work, which was begun at his instigation and has been sought to be carried out in accordance with his suggestions.
