The aim of this invention is to improve the parts of what are known inthe art as cylin-" 1o der prihting-presses7and .cylinder'perfect ing printing-presses, j My inventionis especially adapted to such a press in which a web is printed upon. 1

I will now describe my' improvements as I applied to a traveling-cylinder web-printing press or more particularly to a traveling-cylinder web-perfecting printing-press, it being understood, as hereinafter described, that my improvements are not limited to such specific form of press.

Referring to the accompanying four sheets of drawings, Figure lis a diagrammatic view of one form of press with my improvements applied thereto, showing the feed of the web around the impression cylinders taking place. Fig. 2 is a similar diagrammatic view showing the cylinders as printing. Figs. 3 and 4c are enlarged elevations showing the particular web-guiding mechanism used in connection with one of the cylinders. Figs. 5 and 6 are views of one'of the cylinders, the cylinder being shown as off and on the forms on the bed, respectively, illustrating a modified form of myinvention. Figs. 7 and 8 are views similar to Figs. 5 and 6, illustrating a further modification of my device. Figs. 9 and 10 are similar views illustrating still another modification, and Fig. 11 is a perspective view of one of the parts used in the modification shown i'nFigs. 9 and 10.

The action of the traveling-cylinder printing-press,whether the same prints on one side of the web or two sides of the web, is well understood in'the art and, briefly stated, is as follows: The web is held stationary while the printing takes place and is pressed onto a form placed upon the stationary bed by means of the traveling impression-cylinder. Then. when the traveling impression cylinder is I the impression-cylinder, so that at the next the same arrangement of printing mechanprinting movement of the impression-cylinder a fresh portion of the web can be printed.

. It will be: seen that the shifting action of the web necessarily draws the web around the impression-cylinder, and hence there must be considerable friction between the impressioncylinder and the web. This friction renders the feeding action hard, and the friction on the second impression-cylinder in a perfecting-press is very apt to smut or blur the firstprinted side of the web.

The aim of my invention is, broadly, to provide means whereby the web is cleared of or separated from the impression-cylinder when the feed takes place, so that when the web is intermittently shifted the same will not have to be dragged around the surface of the impression-cylinder.

My invention can be applied to any form of traveling-cylinder printing-press, whether the same employs one cylinder and a bed or a plurality of cylinders and beds, and my invention can be applied to all the cylinders or to any one of the cylinders of such form of press.

I have shown in the diagrammatic views one form of press simply to illustrate the way the web is cleared of or separated from the impression-cylinders when the feed takes place;

I have shown in these diagrams substantially isms as is shown in Letters Patent to John H; Stonemetz, No. 376,053, granted January 3, 1888, and a perfecting form of press, it being understood, of course, that the beds may be arranged in any of the well-known manners without departing from the scopeof my inventi0n,and,further,that myinvention may be applied to the single cylinder of a single printing-press or simply to the second cylinder of a perfecting form of press; but I prefer in most cases to apply my invention to all the cylinders in a press, so -that the feed can easily take place. .I contemplate, however, as before stated, in some cases only applying my invention to the second cylinder of a perfecting form of traveling-cylinder printing-press, so as to prevent smut or offset of the web on the second impression-cylinder when the web is pulled or shifted around such second impression-cylinder.

Referring now to the diagrams, I will describe the form of press that I have chosen to illustrate the application of my invention.

Referring to Sheets 1 and 2 of the drawings, it will be seen that A and B represent two stationary form'beds, which are arranged end to end or in substantially the same horizontal plane, and that O and D represent two traveling impression-cylinders adapted to coact, respectively, with forms placed upon the beds A and B.

E represents in outline the reciprocating carriage in which the impression-cylinders and guides are mounted, the carriage E being simply shown in outline to indicate which parts travel and not being a correct representation of the cariage,and this carriage E is supposed to be reciprocated forward and backward parallel with the form-beds by any of the usual driving mechanisms, not necessary here to show or describe at length. Mounted in the carriage at each side of each impression-cylinder are the form-rollers F F, which are used to properly ink the forms in the wellknown manner.

G represents the web-roll, from which the web may be led in the usual manner into the press. From the web-roll Gr the web may be led in through the continuously running rollers 15, 16, and 17 around the looping feeding-in roller 18, which is mounted in arms 19, pivoted on shaft 20, and these arms 19 may carry rollers 21, which bear against cams 22, mounted on shaft 23, which shaft 23 is preferably revolved twice for each complete forward and backward movement of the impression-cylinders, whereby the proper length of web will be fed out when the impression-cylinders reverse in either direction. The rollers 21 may be kept normally against the cams 22 by means of springs 24:, as shown. From the looping-roller 18 the web passes around the stationary roller 25 and then to the roller 26, mounted in the end of the framing. From the roller 26 the web is led around the rollers or guides 260 and 27, mounted in the carriage beneath the impression-cylinder O, and then up around the, rollers or guides 28 and 29, also mounted in the carriage E. From the guide or roller 29 the web is carried across the press to the usual stationary adjustable register-roll 30, and from the roll 30 the web passes back to the rollers or guides 31 and 32, mounted in the carriage E, then under the impression-cylinder D, then up around the rollers or guides 33 and 3%, also mounted in the carriage E, to the stationary guide or roller 35. From the roller 35 the web is led down around the stationary guides or rollers 36 and 37, around the looping delivery-roller 38, which may be mounted in arms 39, pivoted on the shaft 40, and these arms 39 may have rollers 11, which can bear on the cams 42, mounted on the shaft .3, which shaft 43 may be geared to turn synchronously with the shaft 23, but in the opposite direction. The rollers 41 may be kept normally against the cams 42 by means of springs 44. From the looping-roller 38 the web is led continuously out of the press by means of the continuously-running delivery-rollers 51, 52, and 53.

Any suitable inking apparatus may be used to supply ink to the form-rollers and may be mounted on either or both ends of the beds, as desired. The preferred form of inking apparatus consists of fountains H, vibrating ductor-rollers 45, drum-cylinders 4G, carrierrollers 47 and 48, and the drum- cylinders 19 and 50, which drum-cylinders are arranged a distance apart substantially equal to the distance between the form-rollers F F at each side of each impression-cylinder.

As shown in the drawings, an inking apparatus is arranged at each end of each bed and so that a full discharge of ink will be given to the form-rollers on each side of the impressiomcylinders when the impressioncylinders are off the form-beds in either direction. Any other suitable or desirable inking mechanism can be used.

The form-rollers F may bemounted in suitable hangers f, attached to the carriage E, or in any other suitable manner, so as to drop down on the drum-cylinders 4:9 and 50 as the carriage reverses in either direction.

The preferred form of my inking apparatus, which is shown in Sheets 1 and 2 of the drawings, is a great improvement in this class of presses in that a full charge of ink is sup plied to both of the form-inking rollers at each end of the bed.

In the ordinary traveling-cylinder press as the same is arranged in its best form to-day ink is supplied to the form-rollers on each side of the impression-cylinder, either to both form-rollers when they are otf the bed in one direction or to one roller at each end of the bed.

' Myimproved invention of supplying a'full charge of ink to the form-rollers at each side of the impression-eylinder when they are off the form in either direction gives really a double inking for each impression. Thus, for example, taking the case of the impression-cylinder C, it will be seen that as the same moves to the right the form on the bed A is inked by the form-inking roller F to the left of the impression-cylinder O,which formroller F has just received a full charge or supply of ink from the left-hand drum-cylinder 50. Vhen the impression-cylinder is off the form-bed at the right, the left-hand form-roller F will receive another full charge or supply of ink from the right-hand drum 50, and as theimpression-cylinder moves back over the form upon the bed A the form will again be inked. Thus there will be two full ink deposits on the form for eachimpression, the form-inking roller at the right of the impression-cylinder C acting in the same way in connection with the drum-cylinders 49. In other words, the form-inking rollers on both sides of the impression-cylinder are supplied with a full charge of ink at bothends of the form, which gives a double ink-supply to the form, thus enabling my press to be appliedto a nice and fine class of bookwork. I am aware of the inking apparatus shown in Letters Patent to Stoneinetz, beforereferred to, and also of Letters Patent to J. L. Cox, July 5, 1892, No. 478,503- In the Stonemetz device the forms are inked only once for each two impressions; In the Cox device the forms are inked once for each impres sion, while in my improved device the forms are fully inked twice for every impression,

' eling over the forms the web in the press will remain stationary, but so that when the impression-cylinders are off the forms in either direction a fresh length of web will be pulled forward through the press, the web at all times running continuously into and out of the press.

It will be seen in the common organization of a press of this character that when the web is intermittently shifted the same will be dragged around the impression-cylinders, as when the carriage reverses as the feed takes place the impression cylinders are nearly stationary, whereby there will be a great deal of friction between the web and impression-cylinders.

My invention consists, broadly, in clearing the web out of contact with the impressioncylinder while the intermittent feed around the same takes place and in allowing the impression-cylinder to bear on the same while web clear of the impression-cylinders while the feed takes place, the feed thus taking place while the webis 'clear of the impressioncylinders.

I In Fig. 2 the guides are shown as in their normal position and the impression-cylinders as bearing on the Web and printing.

There are many ways in which theweb may be moved clear of the impression-cylinders during the feed and allowedto come back on the impression-cylinders when the printing is to be done. a

The preferred form of myinvention is shown in Figs. 3 and 4 as applied to the second impression-cylinder D, it being understood, of course, thatthe same device-is applied, if desired, to the first impression-cylinder O. In thisdevice the guides or rollers 32 and 33, by which the web is led under the second impression-cylinder D, are shown as mounted in arms 63 and 64:, which arms 63 and 64 are journaled or hung on the shaft 0 of the impression-cylinder D, whereby the rollers 32 and 33 can be moved on arcs about thecenter of the impression-cylinder D. On the sides of the frames which constitute the carriage E are mounted frames K. These frames K are mounted on the frames of the carriage so as to be vertically movable thereon,and one convenient Way to so mount the frames K is to cut a slot is inthe same, which slot embraces and fits on the shaft 0. Above and below the slot are also formed slots, as 54 and 55, into which slots screws, as 56 and 57, fit, these screws being tapped into the carriage-frames. By this means it will be seen that the frames K are mounted so as to be vertically movable on the carriage-frames. It

is understood, of course, that two' frames K are used in connection with each impressioncylinder on each of the carriage-frames, it being unnecessary to show the other frame K, the samebeing exactly the same as the frame K shown. These frames K have studs 650 se- 'cured to the same, which studs connect by links 65 and 66 to the arms 63 and 6t, which carry rollers or guides 32 and 33. Secured in the lower end of the frameK are the studs 58, on which are journaled rollers 59. These rollers-59 are arranged so as to bear on'suitable guides 60, formed or arranged on the sides of the bed, as shown, and these guideways 60 have suitable'inclines 61 at each end of the bed, as shown, and I preferably ar- IIO range above these cam portions of the guide- 1 ways guards orcams62. Asshown, the rollers 31' and 34 arearra'nged rigidly in the car; riage-frames. The way'this' form of my invention acts is as follows:'-Wh.en the impression-cylinders run off the forms upon the bed, the rollers 59will rundown the incline 61 and also underthe' guards or cams 62. This I will pull the frames K down andwillmove the rollers or guides 32and 33 downward, so as to' move the web clear of" the imp'ression -cyline der D, as shown in Fig. 3. Now whenthe impressiomcylinder is off the formg as shown,

- the intermittent web-shiftin g mecllanisnracts and pulls the web forward; but as this feed takes place it will be seen that there will be no slip between the impression-cylinder and the web, as the web does not touch the impression-cylinder. As the cylinder moves back toward the forms the rolls 59 will run up the cams 61, and the rolls or guides 32 and 33 will be moved to their normal positions or to the positions shown in Fig. 4, when the web will again come into contact with the impression-cylinder D. This action of course takes place at each end of the bed.

In Fig. 4 the impression cylinder D is shown as in contact with forms placed upon the bed B and as printing. The guide 60 is extended across the form-bed, so that during the entire printing operation the guides 32 and 33 are held in their normal positions.

In some cases when it is desired to have very nice work I intend to connect the guides or cams 62, as by a guide 620, as shown in dotted lines in Fig. 3, so that there will be a continuous groove, as 600, for the rollers 59. The guard 62 is useful in that as the feed takes place a tension is put on the web and the guard 62 will prevent the guides being lifted by the feeding action of the web. Another advantage which results from this form of my invention is that the device will also act as aweb-tensioning device-that is, when the guides 32 and 33 are lowered, as shown in Fig. -3, the web will be slightly slacked, so that the feed can take place easily, but when the guides 32 and 33 are extended upwardly or raised to their normal positions, as shown in Fig. at, the slack will be taken up and the web will be kept very taut in the machine during the printing operation, so that a perfect register will be obtained. Thus it will be seen that my device acts also as a webtensioning device as well as a device for au-- tomatically moving the web clear of the impression-cylinder while the feed takes place.

The construction with the first impressioncylinder 0 in the preferred form of my device, where it is arranged to also manipulate the web about the first impression-cylinder in the same manner, is just the same as that shown in Figs. 3 and eand need notoe again here shown or described.

My invention could obviously be applied to a press in which the printing only takes place in one direction, as shown in Letters Patent to W. P. Kidder, No. 291,521, granted January 8, 1884;. but the form of press that I preferably use is the one in which the feed takes place when the impression-cylinders are thrown out of impression in either direction or at each end of the bed.

It is of course obvious that my invention can be applied to a single printing-pressthat is, to a printing-press in which one bed and one cylinder-are usedthe invention being simply applied to the cylinder of that form of machine.

In Figs. 5 and 6 I have shown a modification of my device. In this modification the four rollers or guides 31, 32, 33, and 3 1- are arranged in frames K which are mounted on the carriage-frames E in the same manner as the frames K of the device shown in Figs. 3

and 4., and these frames K have the same operating mechanism as shown in Figs. 3 and at. WVith this modification when the impressioncylinder is 01f the form-bed, as shown in Fig. 5, the frames K and the guides or rollers 31, 32, 33, and 34 will be lowered, so that the web can be shifted through the press without contact with the impression cylinder. \Vhen the impression-cylinder, however, is moved so as to engage the forms, the rolls or guides mounted in the frames K will be raised, as shown in Fig. 6, so that the impression-cylinder will bear upon the web, as shown.

In Figs. 7 and 8 I have shown a further modification. In this modification the rollers or guides 31, 32, 33, and 34: are fixed or journaled in the carriage-frames E, as shown. 0n the carriage-frames E are mounted frames K which are mounted so as to be capable of ver tical motion upon the frames, and one convenient way to mount these frames K is to slot the frames, as at 5% and 55, and to use screws 56 and 57, as in the previous modification. These frames K have formed or secured thereto racks, as 70, and these racks mesh into teeth 72, secured or formed on arms 71, which arms 71 are journaled or hung on the shaft 0 of the impression-cylinder D. These arms 71 carry between them a shield 73, which is made out of smooth or polished metal, and the whole is so arranged that when the shield is swung down that the shield will lift the web off the impression-cylinderbetween the guides 32 and In this modification the cam-slot 610 has to be turned so as to move the frames K upwardly instead of downwardly, as in the previous device, and with this modification I preferably use a strip 621, which extends the entire length of the bed. The frames K have studs 58 and rollers 59, as in the previous device, which runin the groove 600, formed by the guides 60 and 621. With this modification the action is as follows: When the impression-cylinder runs olf the forms in eitherdirection, the frames K will be moved by means of the cam 610,-and by this means the shield 73 will be swung under the impression-cylinder and will. move the web clear of the impression-cylinder, so that the feed of the web can take place without contact of the impression-cylinder. Then when the impression-cylinder moves so as to again engage the form the frames K are lowered and the shield 73 is withdrawn from under the impression-cylinder D and the impression-cylinder can bear on the web to present the same to the forms, as shown in Fig. 8. While this is not the preferred form of my device, still the same possesses many advantages over the ordinary construction, where the web is pulled bodily forward and in contact with the impression-cylinder. The impression-cylinders in most cases are covimpression-cylinder.

or rollers 31 and 34 and the shield L are shown ered with a rubber or felt blanket, and the web necessarily runs very hard if shifted in contact with the impression-cylinder; but by using thedevice shown in this modification the web is lifted clear of the impression-cylinder and is moved over a smooth metallic surface, over which a web can be moved in a very easy manner, as is well known in connection with formers and turner-bars.

In Figs. 9, 10, and 11 I have shown another modification. Thismodificationis arranged and mounted similarly to the modification shown in Figs.5 and 6; but instead of using the two rollers 32 and 33 I use a shield or guard L, which is cut away, as at 1, so that the impression-cylinder can bear on the web through this cut-away portion. This guard or' shield L is preferably turned in on the ends, as at Z, and around the hole Z, as at Z so that it will present a smooth and curved surface for the web. In Fig. 9 the guides 31 and 34-and the shield or guard L are shown as lowered and the web as moved clear of the impression-cylinder, so that the feed can take place without contact of the web with the In Fig. 10 the guides as raised, so that the impression-cylinder can bear on the web through the, hole Z and properly press the web onto the forms. By this means it will also be seen that the web can be shifted without contact with the impression-cylinder. The mounting and arrangement for this shield L is just the same as that for therollers 32 and 33 of the modification shownin Figs. 5 and6 and need not be specifically shown and described. Thus it will be seen that I have provided a device which greatly simplifies and cases the action of the feed andalso a device which greatly lessens the smut of the web. The adj usting mechanism for adjusting the impression cylinder or cylindersrelatively to the forms is not shown in this case, as many-'forms'of the same are well understood and may be arranged in the press so as not to interfere with the peculiar web-manipulating devices before described.

Icontemplate and the scopeof my invention covers the application of my improved invention to anyimpre'ssion-cylinder around which a web may be shifted and, broadly, can be applied to an impression-cylinder which is stationary and with which coact's a reciproeating form-bed. Also my invention is applicable to the form of press shown inmy application filed July 27, 1892, Serial No. 441, 365,

in which two impression-cylinders-are used tions filed by Louis NV. Southgate April 6,

1893, Serial Nos. 469,322and 469,323. In

these last cases two impression-cylinders are shown as coacting with a single form-bed.

As shown, the details of my invention can be greatly modified by a skilledmechanie .without departing from the scope of my inthe impression-cylinder when the shift takes place.
