THE "TIMES" NEW PRINTING MACHINE.

[macmillan's magazine.] As the construction of the first steam ; newspaper machine was due to the enter-; prise of the late. Mr ..Walter, sq the construction of this last and most improved machine is due in like manner to the enterprise of his. son. The new " Walter Machine " is not like Cowper and Applegarth's and floe's, the improvement of an existing arrangement, but an almost entirely. original. invention.: Its principle merits are its simplicity, its accurate workmanship, its compactness, its speed, ;and its economy. While each of the I tten-feeder Hoe' machines occupies a^ large'; and lofty room, and requires 18 m'en to ! feed and work it, the new Walter machine, •ipccTiptes^ a,space:of ronJy 14 feet by: 5, or less thaji any newspaper machine yet introduced, and requires only three lads to; take away, with half the attention of an overseer, who easily superintends two of the machines while at work. The Hoe! machine .turns out 7000 impressions printed' on both sides in the "hour; b,ut the Walter machine turns out 11,000 impressions completed in the same time.; The hew; invention does ; not in the, least; resemble any. existing printingrmachine,: unless it be the calendering machine, wliich has possibly furnished the type of I it. At the printing end, it looks like o collection of small cylinders or rollers. : The paper, mounted on a huge reel as it comes from the paper-mill, goes in at one end in an endless web, 3300 yards in length, seems to fly through amongst the cylindera, and issues forth at the other in two descending torrents of sheets; accurately cut into lengths, and printed on both sides. The rapidity with which it works may be inferred from the. fact, thai the": printing cylinders :(r<oitnd which the stereotyped plates are fixed), while making their impressions on the paper, travel at the surprising speed of 200 revolutions a minute. 'As the sheet passes inwards, it is first damped on one .side, by being carried rapidly over a cylinder which revolves in. a trough of. cold water, it theib passes on to the first pair of printing and ; impression cylinders, where it is printec l on one side ; it is next reversed and sent through the second J pair,, where it : is printed on the other side ; then it passes on to the outting cylinders, which dividb ..the web; of now. printed paper into thJB proper lengths. The sheets are rapidly conducted by tapes into a swing frame, which, as ie vibrates, delivers them alternately on either side, in two continuous streams of sheets, which are rapidljy ihrbwn forward from the frame by ja Crocker,: and deposited on tables at which" ithe lads aft to receive them. The machine is almost entirely self-acting, ! from the pumping up of the ink out of the iuk-box of the cistern below stairs, to the registering of the numbers as they are printed,., in the manager's; room above. Such, in afew words, is the last great invention made in ,<soimeci ; iqn with newspaper printing— which reflects no little credit on the enterprise of Mr Walter, and the inventive skill of the gentlemen of the Times afaff— for it has been entirely designed and manufactured on the premises — to whom he has entrusted its execution.
