5 This invention is a novel improvement in flat bed web printing presses of the type shown for example in my Patent -1,4;75,566 of jNoveniber127, I923and which is known'to the trade as the fComet? press; but the inven- 'tion is applicable to ,other fiat bed web ,per-' }fec tin'g.pressesand might be used in connectionjwlith rotary web printing presses.

i ,QEhe principal object of theinvention is to provide novel means whereby a web (or webs leach?) of onehalf the width (or less) of the gpressuafter'being printed upon by the lower -bed canbe turnedfbetweenthe'beds so it will Qrece'ive second impression in color on the same side of-the web on the topbed the Web returning directly lov er its lower path of travel and :on Ltlie'same side of the press. thisrmea'ns ,Iam able to print in colors on preside of the web, by running two narrow I M widthjrollsof,paperyor slitting a full width Web. 1

A further object of the invention is'toprovi clesuch a press wi h tw f l ing "tllll'llIlg devices.

In the preferred form of the invention I employ-sets of angle bars for turning the :webs -between ,the first and second beds or eo printingmechanisms, such anglebars when v :lappliedto'a flatQbedpressbeing located at the rear \endofthe ,'pre s s, and the folding or delivery "mechanisms being located at the rdrive end of thepress and preferably on opposite'sides thereof. ",llvithgsuch angle bars --ar i'd-,two deliverieslean utilize np tothefull printing capacity of the press to print a full width Web or its-equivalent for bill work. Also to deliver two single page bills in: colors,

delivering devices in accordance with my invention and an understanding thereof will enable others skilled .in-theart to adopt and use the invention. In the claims I have summarized the essentials of the invention and :the novel features of construction and novel combinations of parts for all of ivhich-prqt tion is desired.

These cylinders are mounted in hearings in crossheads3 which are reci'procated-to.move-the' cylindersfl and 2 back andforth over the beds, prefer-ably by means of pit'men 3 connectingthe'crosa heads 3 with crank gears l. The press is pro vided with web 3 feeding, guiding and deilivery mechanism. The, press shown isof the type illustrated'inmy Patent1,l75;56and1is fully describedltherein andthe general conend angle bar attachment the bill could be 19 Figure-1 1s a diagrammatic s de elevation struction, and arrangement of such -machine andof the aforesaid parts are Well known and needno further detailed explanation herein,.but as statedtheinventionis applicable to other types of presses.

In the press shown when is desired to print an ordinary newspa-per,-or perfect-both sides of a web the '.,.web 9.0 isled from the" roll WV underan idler guide roller 9 to an'infeed roll 5, thentheweb isled under aguide roller g'to a gnide roller 9?, andthen back over .a

"looping roller 16 Theweb then'led over the bed 1 and under the cylinder 2 to and over a guide roller g mounted on the crossheads adjacent cylinder 2, and up over a guide g mounted on the crossheads beside cylinder 2 the web thenpassesto a stationary guide g on the frame; and up over a roller 9 on the frame; thence inwardly over bed 1 to a guide 9 on the crossheads adjacent or to print twona-rro-w webs,or twosections of a wide web, in multicolor if desired; to print onenarrow web or web section in multiicoloron oneside and perfect the other narrow web or web section in one color; and to provide means whereby such narrow webs or web sections can be delivered either together, or separately. a p

In order to enable the press to print a. nargrow web or two sections of a' webin multi- '30 color on one side, I provide two sets of web turnin devices intermediate the upper and lower'beds and-{cylinders and preferably located adjacent the rollers {g and 9 Each set of web turning devicescomprises upper and lower angle bars 10 and.10, and intermediate guide rollers 10*and 10?, which are at right angles to the guides g and 9 These web turning devices are properly supported in suitable framing not shown, which can be readily supplied by the pressdesigner, and

one set with turning devices is conveniently located above the other set of web turning devices to facilitate threading the webs therethrough, p i I ;When it isdesired to print the web on one side in multi'colortwo narrow webs may be used, or the narrow webs may be sections of the wide web w.

As indicated the wide web w may be split either before being printed on the first bed by means of an ordinary slitter, indicated at 8, in Fig. l ;-or the wide web may be slitafter being printed on bed 1, asby a slitter indicated at S in Fig. 1. The slitter can be located at any convenientpoint to divide the 1 web into two sections w and 40 The web w afteripassing the roller '9 is turned over the angle bar 10, and led out to and overthe guide 10"*; then back to and over the. guide 10 and then to and overthe angle bar 10, by which it is directed back to and under roller 10 and'thence up to the roller 9 from which it passes on through the ma chine as above described and receives a second impression in color on the same side from the form on bed 1. The web 10 after passing the roller is led up over a guide l0 to and over the angle bar 1O then to and over the guide 10, then to the roller 10", then to and over the, angle bar 10", and thence to the roller 9 from which it passes on to receive the second impression in color on the same side from the form on bed 1 as above described. I The-two sections wand ve0 of the web after passing the roller 8, may be directed to either folder F or F, which are preferably arranged at opposite sides of the machine as indicated in Fig. 2. If it is desired to deliver both sections to and w to the folder F the webs w and 20 are turned over angle bars 11, at the drive end of the press, and leddirect to the folder F in the usual manner. If desired to deliver both webs w and 20 to the folder F, both said webs can be turned over 2 angle bars 11 and leddirect to the folder F. If it is desiredjto deliver the webs 'wand 'w separately; web w canbe turned over angle bar 11 and sent to folder F, andweb w can be turnedover angle bar 11 and sent to former F. As the manner ofmountin'gand supporting angle bars and folders and the general construction of arrangement of fold- Iers are well known it is not necessa'a'y'to illustrate all these parts in detail.

a-press provided with the described web turning attachments two narrow webs or sections of a wide web can be turned over between the first and second printing couples It will be seen from the foregoing that inand be printedsimultaneously in two colors on the same side.

By providing the press with two folders or delivery devices and suitable related angle bars as described, the product from each half of the press can be led to a single folder or to separate folders. p

A pressequipped with my invention can deliver simultaneously two perfected products; or two multicolor products, or a multicolor product and a perfected product {and these products'can be varied in size. V

The total product of the press can be delivered to either folder; or it is possible to deliver a product up to of the width of the press to either folder, and the=product from the remaining 4 of thewidth of the press to the other folder. 1
