SCIENCE IN THE INDUSTRIAL WORLD 



were not entirely severed by the cutters, but simply per- 

 forated, and then drawn by accelerating tapes, which 

 completely separated them, into a gathering cylinder so 

 constructed that six perfect papers, or any other desired 

 number, could be gathered one over the other. These 

 were delivered to the receiving board by an ingenious 

 device patented by Stephen D. Tucker, of the firm of 

 Hoe & Company. 



The many advantages of this new machine were so 

 apparent that the earlier types of presses were quickly 

 discarded by the great newspaper offices. A London 

 paper, Lloyd's Weekly Newspaper, headed the list, 

 and was followed shortly by the Tribune in New York; 

 while other papers soon followed their example. There 

 seemed to be no limit to the printing capacity of these 

 new presses except the ability of the paper to stand 

 the strain. As many as eighteen thousand perfected 

 papers could be turned out in an hour, although the 

 average was usually a few thousand less than this. 



It was not until 1875, however, that a satisfactory 

 folding device was perfected. Until that time the ex- 

 treme limit of the folders in use was eight thousand 

 papers an hour; but in that year Stephen D. Tucker 

 again came forward with an invention, a rotating fold- 

 ing cylinder, that folded papers as fast as the presses 

 could print them. 



It would seem by this time as if the ingenuity of press 

 inventors must be exhausted, and that the "perfecting" 

 press was as nearly "perfected" as possible. But this 

 was by no means the case. A paltry output of fifteen 

 thousand carefully folded newspapers per hour for a
