To all whom, it may concern:

Be it known that I, LOUIS W'. SOUTHGATE, a citizen of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Improvement in Printing- Machines, of which the following is a specifica# tion.

The aim of this invention is to improve the construction of printing-presses, and especially relates -to web-printing presses, which are known in the art as traveling-cylinder web-printing presses, although some of my improvements, as indicated by the scope of the claims, may be applied to web-printing presses in which both the bed and cylinder move or to printing-presses in which the bed reciprocates and the cylinder is stationary.

My invention relates to a peculiar form of such printing-press, which consists in so arranging the parts that two webs can be printed from the saine form or forms, thereby doubling or multiplying` the capacity of the 1nachine.

Referring to the drawings and in detail, I will describe one form of my invent-ion, it being understood, of course, that the same can be designed and varied by a skilled mechanic to suit the exigencies of any particular location or use or form of press.

Referring to the drawings and in detail, Figure l represents in diagram one form of my improvement applied to a press in which only a single bed is used. Fig. 2 represents a press in which two beds are used and by which, if desired, two separate and independent webs can be perfected. Fig. represents the turner device which is used between the cylinders, and Fig. 4. represents a view of a part I terln the web-reverser.

I will now lirst describe the form of press shown in Sheet l, and referringto the same and in detail A and B represent two impression-cylinders, which are mounted in a suitable reciprocating carriage II, so as to both be capable of coacting with a form or forms placed on the bed D.

E represents a suitable web-turner, which is arranged in thevpath of the web or webs between thc two cylinders.

F F and F2 represent form-rollers, which are arranged, as shown, on the outside of each impression-cylinder, and one, as F, between the two impression-cylinders.

At each side of the bed D, and slightly below the level of the forms placed upon the same, are arranged ink-tables G, projecting through which are the drum-cylinders G', to which ink may be supplied from the fountains G2 by means of the usual vibrating ductor-rollers g.

The form-rollers F F and F2 are mounted in the carriage II, so as to drop onto the inktables G .when they are off the forms, so that when the cylinders are oit the forms in either direction ink will be given to all of the formrollers.

Any other suitable form of ink-supplying apparatus that will give ink to the form-rollers F F and F2 may be used.

The device, as shown, may be used either in connection with a double or single web, the carriage II being reciprocated -by any of the usual and well-known mechanisms for reciprocating the impression-cylinders, and I will describe the way my invention is used first with the single web, as a, which is led from a web-roll, as I'V.

From the web-roll W the web a passes in through the continuously-driven rollers l0, ll, and 12, which will slowly unwind the web from the roll in theusual manner. From the last roll, l2, the web passes up over the looping-roller 13, which is mounted in arms 14E, which arms le have connected to the ends thereof springs, as l5, and connected to these arms le are the pivoted arms 16, which carry rollers I7, which bear on cams 1S, which cams 18 are of any desired shape, this device being so arranged that the web will be fed forward when the impression cylinders are off the forms in either direction, as is well underl stood. From the looping-roller 13 the web passes down under a stationary guide 19, then around the guides 20, 2l, 22, and 23, carried by the reciprocating carriage I-I and arranged around the impression-cylinder A, as shown. From the guide 23 the web is led back around a guide 24 and then to the turner E. This turner may consist of two right-angled forty- IOO live-degree turner-bars, as 25, and 27, and a parallel roll, as 26. From the last turner-bar, 25, the web passes to the guide or roll 28, down under the guide or roll 29, under the im pression-cylind er B,then up over the guides 30 and 3l.

It will be seen that the turner device E is arranged over the first impression-cylinder A and that the web is led back to the same by means of the roller 24. This forms a very compact arrangement of parts, as by this means the impression-cylinders A and B can be kept close together, thereby shortening their stroke and shortening the path of the web.

From the guide 3l the web passes to the guide 33, mounted at the end of the press, then up over the looping delivery-roller 34, which is mounted in arms 35,which are normally pulled down by means of springs 36,` and to which arms 35 are connected the pivoted arms 38, which carry rollers 3f), which bear on the cams 40, and from the looping-roller 34 the web passes into the bite of the continuously-running delivery- rollers 4l, 42, and 43, the action of this delivery mechanism being well understood.

The operation of the press thus organized is apparent.

As the impression cylinders reciprocate back and forth over the forms they will present opposite sides of the web to the same forms and the web will be printed or perfected in the manner which is known as work and turn-that is, if there are two forms on the bed side by side the web will be printed so as to be capable of being slit and cut into sheets, which sheets will be each printed upon one side by one of the forms; or, again, if there are four forms on the bed side by side the web could be perfected so as to be capable of being cut and slit into sheets which would have the matter of two of the four forms printed on each side.

Of course the arrangement of forms may be further varied and carried out, as desired, depending upon the work to which the press is to be applied.

The web may be continuously fed into and ont of the press, as shown, and may be intermittently shifted by the looping-rollers when the impression-cylinders are olf the form in either direction, and this is the' preferred arrangement, although the press might be so built that the web would be only shifted when the impression-cylinders are off the bed in one direction. lt is preferred to move the turner device with the carriage, although, of course, it would be within the scope of my invention to arrange this turner on a stationary part of the machine.

My device can also be used to print on one side of two webs, which are preferably associated, and the way this can be done is to simply associate a web, as l), from the webroll WV with the web a, so that the two webs will be led through the press together, whereby the same feeding and delivery mechanism suffices for both webs, although, of course, it would be within the scope of my invention to use a separate manipulating device for each web. It is preferred when this separate web is used to lead but one of the Webs around each impression-cylinder, although, of course, it would be within the scope of my invention to manipulate the associated double web exactly the same as the single web is manipulated.

Vhen it is desired to lead but one of each of the two webs around each impression-cylinder, the same can be done by simply adding two rollers 32 and 320 'on the carriage, as shown. With this arrangement the webs a and b will travel together as far as the roll 32, when the web a will follow the path above indicated to and about the first impressioncylinder, while the web l) will be led up over the guide 32 to the roll 24, at which point the two webs-a and b will be associated as they pass the turner.

The turner will so manipulate one of the webs, as the web a, which would be led out over the turner 27, around the parallel roll 26, up over the turner 25, that the web a will be placed on top of the web b, and after passing to the roll or guide 28 the web a will be led directly to the guide 320, mounted over the roll or guide 3l, where it will be again associated with the web b, that the two webs may thereafter run as one web. Meanwhile the web b, which after passing the turner device became the lower web, has been led down about the guide 28, beneath the guide 29, under the impression-cylinder B, where it receives its impression, about the guide 31, where it is again associated with the web a. By this means it will be seen that l can use my device to print on one surface of each of two webs. It will be seen, also, that by the preferred arrangement for the two webs last described the first-printed web will not pass under the impression-cylinder B, and hence there will be no offset during the printing operation. Thus this machine, as shown in Sheet l, is capable of a variety of uses, either with a single or a double web.

The form-inking rollers will take ink, as before described, when the impression-cylinders are off the form-bed in either direction, whereby the form can be properly inked so that the impressions can be taken on both the forward and the backward movement of the cylinders.

The emerging printed web or webs can be further manipulated, associated, cut, collected, or folded, as desired.

My invention also is especially applicable to the perfecting form of traveling-cylinder press, and l have shown one arrangement, in Sheet 2 of the drawings, illustrating the perfecting form of my press, it being understood, of course, that the printing mechanisms of a perfecting-press can be arranged in the same plane, or in any other well-known manner, as

fore described.

well as directly over one another, as shown in said second sheet. In this second sheet of drawings I have shown a press, designated as press No. 1,exactly the same as the press described in the iirst sheet of the drawings, and over the same I have shown a similar press, which is designated as press No. 2, consisting of the first impression-cylinder A', the second impression-cylinder B', the bed D', the turner E', the form-rollers F3, F4, and F5, and ink-tables G3, ink-drums G4, ink-fountains GH", and ductor-rollers g', exactly the same as be The press No. l will not again be specifically described, as it is preferred to use the specific press, as before described, in the perfecting form of a machine. i

This perfecting form of press is especially adapted for use in connectionwith the double or associated web, and I will further describe the same as using thedouble web.

From the last continuously-running delivery-roller 43 of press No. l the two associated webs are led upward,as shown, but the web Z) is turned back over the roll 50, and the position of the webs is reversed by a peculiar turner device, which consists of a forty-iive-degree turnerbar 51, which deiiects the web laterally out of the machine, as shown,around a vertical roller 52, then back into the4 press, under a turner 53, which will change the position of the webs, and will bring the two printed sides of the webs together, so that the two webs will be associated at the point where they again unite to form the associated web, which is unprinted, on the exterior surfaces. From the reversing device the associated webs run into the bite of the `continuously-running rollers 54, 55, and 56, and these rollers, acting in connection with the looping device and with the continuously running delivery rollers of press No. l, will more the webs continuously at an even speed through the reverser, which is the preferred form of arrangement. From the continuously-runnin g roller 56 the web is led down under a looping-roller 57 ,which preferably is mounted in extensions 350 of the the impression-cylinder A', then up overthe guides 6l and 62, and to lead the web ct around a roller, as 7l, up to the guide 62, whereby there will be only one web under the impression-cylinder A', and thus one web will not offset on the other. From the guide 62 the two webs are again associated, and the web l) is turned over the web ct by means of the turner E', whichconsists of two right-angled forty-five-degree turner-bars and a parallel roll arranged and constructed as the turner E of press No. l. From the turner the webs pass to the roll 65, and then the web a is carried back by means of guides 66 and 67 uni der the impression-cylinder B', and then up over the guides 68 and 69, all these guides being mounted in the carriage, as shown. It is preferred also not to lead the web b under the impressionecylinder A', but to lead the web b directly from the roll or guide 65, so that the same will again be associated with the web ai as the same leaves the impression-cylinder B', and this can be nicely done by leading .the web b under a guide or roller 72, mounted in the carriage, as shown. From this point the two associated webs pass to a stationary guide 73, around a looping-roller 7 i,which is prefer V ably arranged in extensions 140 of the arms 14, and then into the bite of the continuouslypacity of the ordinary traveling cylinder press is doubled without unnecessarily` in* g creasing the speed of the parts; also, it will be seen that the same feeding and delivery mechanism suffices for both webs, and` two cutters and folders can be used, if desired, one handling each web at alow speed,whereas ifa single web were used the speed of the web would have to be double that of the two webs which I use.

IOO

It is preferred to use a looping device at Y the end of the press, so that the webs will run continuously around the reversing mechanism, so'that the pull of the feed on the web will be slight.

From the continuously-running deliveryrollers J[he webs may be thereafter manipula'ted in any desired manner, either singly or associated.

AThe arrangement of the various details, as before stated, can be varied by a skilled Aprintingpress designer without departing from the scope of myinvention as expressed in theclaims.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-
