MARINONI'S FEINTING MACHINE. 



in the usual manner, at T, T', T", T'", and T"", to spread the ink on 

 the types. 



It will be perceived that the power of this press is equal to that 

 of The Times, the difference being that The Times prints 12000 

 sheets on one side only, while this prints 6000 on both sides. The 

 Times machine requires eight layers-on and eight takers-off, being 

 double the number required by Marinoni's press. It must, how- 

 ever, be observed that, in the practical management of newspaper 

 printing, as conducted in The Times office, the power of Marinoni's 

 press, though in a certain sense equal to that of The Times, would 

 be altogether insufficient; for it is indispensably necessary for 

 that journal to print 60000 copies on one side of the paper during 

 the last five hours of the morning. The matter allotted to the 

 other side of the paper is so selected that it can be composed and 

 printed in the earlier part of the night, or even of the previous 

 day; the pressure falling exclusively on the matter which occupies 

 the other side of the paper, consisting chiefly of the latest intelli- 

 gence and Parliamentary reports. 



It may be asked, therefore, how the journal of La Presse, of 

 which the circulation, though inferior to that of The Times, is 

 still very large, can be printed with the necessary celerity ? The 

 answer is, that La Presse does not contain as much as the tenth 

 part of the letter-press of a copy of The Times, and that therefore, 

 it is found practicable to compose the matter in type twice or 

 oftener, so as to produce two or more distinct forms, as they are 

 called, which are put to work at as many different presses. The 

 expense of composition is further economised at the printing office 

 of La Presse by stereotyping the matter, which is composed at a 

 sufficiently early hour to admit of that process, the stereotype 

 plates being melted down the next day. By this expedient double 

 or triple composition is only necessary for the intelligence which 

 comes too late to allow of being stereotyped. 



27. Marinoni's Book-printing Machine. A convenient form 

 of printing-engine for books, constructed by the same engineers, 

 is shown in fig. 13, by which, however, the sheets are printed 

 on one side only. The layer-on delivers the sheets upon the 

 board M (fig. 14), from which they pass round the printing 

 roller i, and are discharged as indicated by the arrow upon the 

 receiving-board n. The rollers for delivering and spreading the 

 ink on the types are arranged in the usual way. 



28. Newspapers. Of all the applications of printing to the 

 uses of life, that which has conduced most to the advancement and 

 improvement of the art has been the printing of newspapers. 

 These organs of public opinion and intelligence combine the con- 

 ditions which require from the printing press the greatest con-
