ROTARY PRINTING-PRESS.

Specification of Letters Patent.

Patented Jan, 26, 190,9.

To all whom 'it may concern:

Be it known that I, FREDERICK M. TURCK, a citizen of the United States, and resident of Rosebank, in the county of Richmond and State of New York, have invented certain new and useful Improvements in Rotary Printing-Presses, of which the following is a specilication.

The invention relates to improvements in rotary printing-presses of the class described in my prior patent No. 830,751, dated September 11th, 1906, and to which reference may be had for a full description of the complete machine.

rPhe present invention includes a single impression cylinder cci-acting with a pair of type cylinders upon a web of paper, and the obycct is to provide meansfor readily varying the diameters of the several cylinders to secure an increased printing range for the machine, whereby several sizes of printed sheets may be obtained.

A further object provides for the rapid and accurate operative adjustment of the several cylinders.

rl he invention also p`r ovides means for releasing the pressure upon the impression cylinder to permit the web of paper to be introduced or threaded and accurately adjusted in relation to the several parts comprising the machine.

1n describing the invention in detail reference is had to the accompanying drawings, forming art of this specification, and 'wher-e in like ciaracters of reference are used to designate like arts throughout the several views, and in wliich- Figure 1 is a side elevation of a part of the machine pertaining to the resent invention. Fig. 2 is a ground plano a ortion of the rear frame of the machine, in W lich are journaled one end of the several cylinders with their respective driving gear. Fig. 3 is a transverse sectional view of a part of the front frame, illustrating the journal-boxes carrying the opposite end of the cylinders. Fig. 4 is a detail transverse section of one of the cylinders. Fig. 5 is a spacing block adapted for use in connection with the lower type cylinder.

umerals 1 and 2 designate respectively a portion of the front and rear frames of the press, each of which frames being provided l ders, as indicated by thedotted circles 3, 4

and 5, the gears for cylinders 4 and 5 being respectively designated by 4and 5, These gears interinesh with one another and are in turn driven by the pinion-gear 6, fixed upon the shaft 7, the frame and provided with a driving pulley 8.

The im ression cylinder is provided with the usua blanket and connecting means therefor, and to the two type cylinders are aflixed the printing forms with their necessary attachments.

When it is desired to increase the dialneters of the printing couples, consisting of the impression cylinder andthe two type cylinders, a two part jacket 9, (see Fig. 4) preferably formed of metal, is removably se cured to the body of each ol` the cylinders and over the ackets, are secured respectively the aforementioned blanket and printing forms. Driving gears corresponding to the increased diameter of the cylinders replace the former ones and these operatively engage with one another and with the pinion gear 6.

The changes in the diametrical dimensions of the printing couples are accomplished without the removal of the several cylinders from their journal-boxes and without dis` turbin the horizontal path of the printed web, tie latter object being essential in the further action of the press and the former purpose insures a considerable saving of time in its operation. For the accornp ishnient of these objects with respect to the upper type cylinder 4, journal-boxes 10 are provic ed having eccentric boxes to receive the journals of the cylinder, the boxes being rotatably mounted inthe frames and secured in operative position with bolts. Upon the removal of the bolts, pin-wrenches may be utilied to engage the bolt perforations in the boxes to turn the latter for pro erly ositioning the dual-size cylinder inicate by the broken circles 4 and 4b, such position permittin the respectivecylinder-gearsto engage t e common pinion-geert and -to colatter being journaled in the ed in vertieally-slidiinr boxes 112, which hitter i ai 1guided bv the I'rztnies ol thil prees :nld by tlw` sido blocks I3. 'l`h4l construction and tuition ol' the eccentric Journal-boxes ll rire similar to that olA boxes l), in that it permits the duel size impression cylinders 13 :ind Si" and their connected genre to roepen tively cn-A gitge their ioircsponiling type cylinder; nod gears 4 and fill.

'lhe lower type cylinder 4 is nionntml in the horizontalI yhulii[able journal-lirios 111, whieh. nre -gnided and supported by tho l'rauics ol' the press. The ziperal-ive pi il ion. olA this type t 'linder with respect lo iis co acting inip'reusitm rylinder is innintnincd by the ailjustingscrews 15, which urge the journaldioxcs against the heed sido blocks 13. The adjustment of these boxes in rele tion to side bloc-lis 1? l'orrthe :tcroininodntion of the enlarged type cylinder 5b, acting in connection with the enlarged impression cylinder Z5", is obtained by interposing spat-ing blocks 1b, shown in detail in Fig.

The frames 1 and 2 nre provided with re I (fesses below the slidingl boxes 12, end within the recesses ore mounted the rerrierdiloeks 1T which engage eeeentries 1S, l'ornied on` shaft 10, the latter being rotatably mounted in the frames ol the press and actuated by the bruid lever 2G to operate the verrierbloclis lor raising and lowering the sliding boxes 12, which support the impression cyl inder.

t will be evident that by means ol the adjusting-screws 15 the operative Contact between type cylinder 5 and impression eylv inder S3 may be released, sind through the operation ol the hand cylinder may be separated from the upper type cylinder L1, whereby the web ol' peper may be introduced couples and through position properly adjusted.

21 designates an ink-distribetingI cylinder adapted to be rotated through its connected f l driving gear 22 from the pinion neer 6, and is arranged to rece've a supply of ink from :in

ink fountain in t 1e usuel manner, and 23 and 24 indicate conventional forni rollers for ap.- plyineT the ink to the printingr cylinders.

, As the operation'of the various parts of the machine have been set out in detail end in the connection wherein theyv cooperate with each other it is believed a reca pitulation ol the en tire operation is unnecessary. It is apparent, of course, while l illustrate end describe the preferred embodimentl of the invention it is susceptible of various changes as regards lever 2t) the impression between the printing` the nmoh'uie. and its l its form, proportion, detail construction, end arrangement of parts without departing from the essential spirit and scope or sacri- Iicinir nny of the advantages of' the invention.
