PRINTING, PROGRESS OP, IN RECENT YKAlts 



tional inventions of their own they evolved the 

 perfect folding apparatus used upon the large 

 double-supplement, quadruple, sextuple, and oc- 

 tuple machines made by them. These presses 

 have revolutionized the art of printing news- 

 papers. They print upon 1, 2, or 3 rolls of paper, 

 giving 4-, 6-, 8-, 10-, 12-, 14-, 1G-, 20-, or 24-page 

 papers, as required, delivered folded, pasted, and 

 counted, in piles, at speeds varying from 12,000 

 to 150,000 perfect papers an hour. These ma- 

 chines may be seen in all the large newspaper 

 offices in the United States, Great Britain, Aus- 

 tralia, and New Zealand. The largest of them 

 weighs about 58 tons, and is composed of 16,000 

 separate parts; but, notwithstanding the number 

 of pieces composing these machines and their ap- 

 parent intricacy, they are extremely simple in 

 principle and in operation. All the devices in 

 them, including the triangular formers and the 

 principle of handling the paper and keeping it en- 

 tirely in the endless sheet, or web, until the final 

 fold, are the result of great study and ingenuity, 

 and the subjects of many patents. 



Rotary Machines. The great improvements 

 in the making of electrotype plates, and the in- 

 creased economy and accuracy with which they 

 can be produced, have led to their use 

 upon rotary presses. These machines 

 are often referred, to as magazine press- 

 es, being adapted to the wants of maga- 

 zines or other illustrated publications 

 requiring a good grade of work at a 

 high rate of speed. Such machines not 

 only print papers of multiple pages, but 

 place upon them, automatically, covers 

 of different colored paper, and stitch 

 the product together with wire staples 

 as the papers issue from the machine, 

 at the running speed of 12,000 or more 

 copies an hour. 



The rotary principle has been car- 

 ried to still greater perfection for fine 

 wood-cut and half-tone work in ma- 

 chines made for Theodore L. De Vinne 

 & Co., printers of the Century Maga- 

 zine. These machines deliver the pages 

 of periodicals and other similar work, 

 printed on both sides, in signatures, folded 

 together, without smutting, and ready for the 

 binder. Some are made to print from the end- 

 less roll, and others to feed by hand; but the 

 curved electrotype plate is used in all, it being 

 found that equally good work and greater 

 economy in production may be had from the 

 rotary system than from the cylinder presses that 

 take the impressions from type or plates placed 

 upon a reciprocating flat bed. Simultaneous poly- 

 chromatic printing on the rotary system is one 

 of the most remarkable developments in news- 

 paper and periodical printing. Many journals 

 now print, with their large weekly editions, illus- 

 trated supplements in colors and half-tone, one 

 side of the sheet having colors and the other 

 Tiaving engravings in black. These machines 

 print at the rate of about 26,000 4-page sheets an 

 hour. They print from curved electrotype plates, 

 the cylinders being arranged so as to give a sepa- 

 rate impression surface for each color. The papers 

 are delivered folded, without marring the pic- 

 tures. 



The Scott rotary web perfecting press is the 

 production of Walter Scott, who began life as an 

 engineer and pressman on a Chicago daily. It 

 was originally an elaboration as well as a sys- 

 tematizing of the Bullock. Scott constructed 

 the first combined printing and folding machine 

 that fed from a joll and produced perfect copies,

 It is really 4 8-page printing-machines arranged in

 sired. It is also built of double width, with quad- 

 ruple folders, in which form it will- deliver 100,000 

 8-page papers completed within one hour. 



Among the smaller web machines made by 

 Scott & Co., the " all-size " rotary has attracted 

 much attention. Most rotary web printing- 

 presses are built to produce newspapers or peri- 

 odicals of a certain size, and they will not print 

 a larger or smaller page, though the number of 

 pages issued at a printing is variable. In the 

 " all-size " rotary, any size of page within the 

 capacity of the machine may be produced, the

graduations being in quarter inches. In 1899 

 Scott & Co. brought out a new two-revolution 

 press with a flyless delivery, and a new bed mo- 

 tion permitting of high speed with accurate regis- 

 ter. This machine has been very successful, but 

 has been almost eclipsed by Mr. Scott's latest 

 invention, in which he has combined the good 

 points of the stop-cylinder and the two-revolution 

 machine. This press, as arranged for lithographic 

 work, is illustrated herewith. The bed motion is 

 new to this side of the Atlantic, being an improve- 

 ment on the German type of " sun and planet " 

 driving gear. The cylinder is made two-revolu- 

 tion, so as to secure small diameter, and is geared 

 to the bed throughout the printing stroke. It 

 comes to a full stop at the point of taking the 

 sheet, thus insuring absolute register, without 

 that loss of speed which has been the drawback 

 to the stop-cylinder class of presses. 



The Campbell Printing-Press Company became 

 famous through the inventions of Andrew Camp- 

 bell. He was the first to build a simple cylinder 

 press for country newspapers, one that could be 

 run without skilled labor, and would do good 

 work, and thousands of them are in use to-day. 

 He built a whole line of cylinder printing-ma- 

 chines for all classes of work, his crowning effort 

 being the production of a web perfecting press in 

 1875. This machine printed, inset, pasted, and 

 folded any number of pages up to 24. It had
