SPECIFICATION forming part of Letters Patent No. 569,434, dated October 13, 1896- Application filed May 15, 1893. Serial No. 474,363. (No model.)

To aZZ 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 XVorcester and State of Massachusetts, have invented a new and useful Improvement in Printing-Presses, of which the following is a specification.

The aim of this invention is to improve the details and arrangement of parts in presses which are known as traveling-cylinder webpresses and traveling-cylinder web-perfecting presses, and to this end the invention consists of the arrangements of parts described in this specification, particularly 1 5 pointed out in the claims, and which are illustrated in the accompanying three sheets of drawings, in which- Figure 1 is a rear elevation of a printing press with my improvements applied thereto.

Figs. 2 and 3 are small plan views illustrating details of the gearing. Fig. 4 is a section, on an enlarged scale, illustrating the delivery mechanism. Fig. 5 is a front elevation of the cutting-cylinders removed from the press.

Fig. (5 is an end elevation of the gearing used between the cutting-cylinders. Fig. 7 is a sectional elevation of the feeding-in mechanism. Fig. 8 is a plan of the change-cams used for varying the length of the sheet, and Fig.

9 is a side elevation of the same.

Hy invention consists in improving the details and arrangement of parts in travelingcylinder printing-presses, such, for example, as is shown in Letters Patent No. 376,053,

5 granted to John H. Stonemetz January 3, 1888,

and while I have shown in this case substantiaily the same arrangement of beds and cylinders, it is understood, of course, that some of my combinations may be applied to presses in which the beds are arranged in diiferent ways, the particular arrangement, of course, being immaterial to the printing operation.

Referring now particularly to the drawings, and in detail, 11 11 represent the usual side 5 frames of the machine. A representsthe first impression-cylinder; B, the second impression-cylinder; C, the first stationary bed; D, the second stationary bed; E, the carriage in which the impression-cylinders A and B are mounted, and G G two sets of inking apparatus mounted at the ends of the press, which are adapted to supply ink to the form-rollers F F on each side of the impression-cylinders, as shown.

H represents the paper-roll, from which the 5 5 web may be led into the press. The path of the web through the press is as follows: From the roll H the web is led between the first feeding-in roller 12 and its friction or pressure roller 13, then down under the second continuously-running feeding-in roller 14, then between the third continuousl y-runnin g feeding-in roller 15 and its eooperatingfrio' tion-roll 16. These rollers are driven continuously, as by the gearing hereinafter described, so that the web will be continuously drawn from the web-roll and paid into the machine. From the roll 16 the web passesdown under the looping-roller l7, and then up over the stationaryguide-roller1S. From the guiding-roller 18 the web is led to the roller 19, which is mounted at the end of the press, as shown, and from this roller 19 the web passes to the roll or guide 20, carried by the carriage E,then under the impression-cylinder A, then up over the roll or guide 21, mounted on the opposite side of the impression-eylinder A relatively to the guide or roller 20. From the guide or roller 21 the web passes to the roller mounted on the framing of the ma- 8o chine, and which roller 22 may be adjustable for the purpose of obtaining register between the two impression-cylinders. From the register-roll 22 the web is led around the stationary guide-roller 23, then across the press to the guide-roller 21, mounted as shown. The rollers 19, 23, and 24: are preferably continuously driven, as by the means hereinafter described so that they will tend to coax or comb the web forward, so that when the web is allowed to pass forward by the looping-roller 17 the same will be quickly moved around the impression-cylinders. From theguide or roll 21L the web passes to the guide or 1'01125, carried by the carriage .E, under the second 5 impression-cylinder B, and then-around the guide or roller 26, also carried by the carriage E. From the roll 26 the web is then led to the roll 260, which is mounted in the framing of the machine, down under the looping-roller I00 27, then up over the continuously-running roller 28, down around the continuously-runnin g roller 29, then up over the continuouslyrunning roller 30, between the same and its friction pressure-roller 31, out over the guidefingers 32,and then between the upper cuttin cylinder and the lower cutting-cylinder 34.

The upper cutting-cylinder 33 may have any approved form of knife, as 330, and the lower cutting-cylinder may have any approved form of receiving edge or shear, as 340,so arranged that when the knife and shear come together a sheet will be positively severed from the web.

The lower cutting-cylinder 34 is grooved, as shown, and running in these grooves are the tapes 35, which pass around

suitable tapepulleys

360, 36, and 37 and lead the sheet thus severed from the web out over suitable folding-rollers 39, into which folding-rollers the sheet may be tucked by a suitable folding blade, as 41, and from the folding-rollers 39 the sheet may be given to a second set of folding-rollers 40 and folded and delivered from the machine either by subsequent folding-rollers or as desired.-

As thus far described the parts are the same as shown and described in an application of John H. Stonemetz filed July 14, 1893, Serial No. 480,528, and my invention consists, as hereinafter described, of a peculiar and simple form of gearing by which the length of the sheet printed and manipulated can be easily and quickly changed, as desired, without .affectin g or altering any of the parts of the machine. This gearing for driving the various parts before referred to may be arranged as follows: 42 represents the driving-shaft of the machine, to which power may be applied in any of the usual manners, as by a tight and loose pulley, and the machine may be started or stopped by any suitable means, not necessary here to describe. On this shaft 42 may be arranged a suitable balance-wheel 43, so that the power imparted to the machine will be even and steady. On the driving-shaft 42 is arranged a pinion 44, which meshes with and engages a pinion 46, which pinion 46 is mounted on and secured to a shaft 45, which I term the main shaft,and from this main shaft the carriage may be moved forward and backward by any of the usual means, not necessary here to show or describe at length, as any means, of course, can be used for imparting a reciprocating motion to the carriage E and its various parts. The gear 46 meshes with and drives a gear 50,which runs on a stud secured to the rear frame 11, and arranged to mesh with this gear are two intermediates 51 and 52, the last intermediate, 52, of which meshes with and engages the gear 53 of the lower 7 cutting-cylinder, and the gear 53 meshes with and engages the gear 54 of the upper cuttingcylinder. By this means it will be seen that the cutting-cylinders will always be driven at a constant speed relatively to the movementof the carriage, and thus the cuttingside end of this shaft 55 is mounted a gear 58.

Journaled on the bracket 57 is a sweep 59, which sweep 59 can thereby be turned about the gear 58 as a center, and which sweep 59 carries a gear 60, which is constantly in mesh with the gear 58. Extending outward from the under part of the rear frame '11 is a bracket 590, which carries a suitable shaft 591, and on the outside end of this shaft is secured a removable gear 61. This gear 61 is set in the same plane as the gear 60 on the sweep, and the bracket 590 has an extension 592, to which the sweep 59 can be secured, as shown. The gear 61 can be removed from the end of the shaft 59 and other gears, as 610 and 611, substituted, and the sweep and its gear 60 can be adjusted and moved so that the gear 60 will properly engage whatever gear is put on the end of the shaft 591. By this means a variable speed can be imparted to certain parts of the mechanism, as hereinafter described. On the inside end of the shaft 591 is secured a bevel-gear 63, which meshes with and engages a bevel-gear 64, mounted on a horizontal shaft 65, which extends nearly the entire length of the press, as shown, and which is journaled in suitable bearings secured to the side frame 11, as shown. Just back of the bevel-gear 63 on the shaft 591 is secured a gear 62. This gear meshes with and engages a gear 66, which is secured on the outsideend of a short shaft journaled in an extension .570 of the bracket 57, as shown, and on the inside end of this shaft is secured a gear 67, which meshes with and drives an intermediate 68, journaled on a stud secured to the side frame 11, and this intermediate 68 meshes with and engages a gear 69, secured on the outside end of the second deliveryroller 29.

The delivery-rollers are geared to turn together, as by means of the gear 70 on the delivery-roller 29, the gear 71 on the deliveryroller 28, the gear 72 on the delivery-roller 30, and the gear 73 on the pressure-roller 31, this gearing being suitably intermeshed, so that the delivery-rollers will turn in the proper direction. By this gearing it will be seen that the cutting-cylinders are always driven at a constant speed relatively to the movement of the impression-cylinders, but that the speed of the delivery-rollers can be varied by the change-gearin g before described. Also it will be seen that when the change-gearing is variedthe speed of the shaft 65 will be varied, and this shaft 65 is used to operate other parts of the mechanisms, as will now be debevel-gear 75, mounted on the upright shaft 76, which is journaled in suitable bearings secured to the frame 11 and which carries at the top thereof a bevel-gear 77, which meshes with and drives a bevel-gear 78, fastened on the end of the third feeding-in roller 15. This roller 15 also has a gear 79 mounted on the same, which drives a gear 80 on the end of the pressure-roll 13, and the gear 79 also meshes with a gear 81, secured on the end of the shaft of the second feeding-in roller 14, which gear 81 meshes with and drives a gear 82, secured on the end of the first feeding-in roller 12, and this gear 82 meshes with and drives a gear 83, secured on the end of the pressureroll13. By this means it will be seen that the continuously-running feeding-in rollers and their pressure-rollers will be constantly driven, but that, as the change-gearing before referred to is varied, the speed of the feeding-in rollers will be varied. This shaft is also used to drive the two sets of inking apparatus at the ends of the machine, and as the gearing is the same at both ends a description of one end will suffice. On the ends of the shaft 65 are mounted bevel-gears 84:, which mesh with bevel-gears S5, and by means of

suitable gears

86, 87, 88, and 89 the distributing-rolls and cylinder-rolls of the inking mechanism may be driven. Also it will be seen that as the speed of the change-gearing before referred to is varied the speed of the inking apparatus will also be varied.

It is desirable to change the speed of the inking devices to correspond with the length of the sheet printed, as by this means, if the inking mechanism is set to properly act for one length of sheet, as the machine is adjusted for another length of sheet, the speed of the inking devices will be changed, so that the amount of ink taken through the ink-distributing apparatus will be varied to correspond.

On the same shafts as the gears 89 are arranged band-wheels 90, from which suitable bands or cords 91 are led up to suitable pulleys 92, mounted on the ends of the shafts of the rollers 19 and 24. These bands 91 may have suitable tighteners,as 93. By this means it will be seen that the rollers 19 and 24 are constantly driven, and also it will be seen that as the speed of the change-gearing before referred to is varied the speedof these continuously-running guides or rollers will also be varied.

Arranged on the shaft of the third feedingin roller is another band-wheel 94, from which a suitable band 95 is led around a pulley 96, mounted on the end of the guide or roll 23, and this band may have a suitable tightener, as 960. By this means it will also be seen that the guide or roller 23 will be continuously driven and that the speed of the same will be varied as the speed of the changegearing is altered. Thus, by the gearing before described, it will be seen that the cutting-cylinders are driven always at a constant speed relatively to the movement of the impression-cylinders; but it will be seen that as the change-gearing is varied the speed of the feeding-in rollers, the feedingout rollers, the inking apparatus, and the continuously-running guide-rollers will all be varied from the same change-gearing, which is very useful for a purpose hereinafter described.

The gearing herein shown and described may be varied and proportioned by a skilled designer to fit the particular machine to which the same is to be applied without in the least departing from the scope of my invention.

The register-roll 22 is mounted in suitable adjustable bearings 98, which may be adjusted by means of screws 97, whereby register between the two impression-cylinders can be easily obtained.

The feeding-in rolls are peculiarly arranged and mounted as follows: In the frames 11 are arranged suitable bearings 99, in which bearings 99 are mounted vertically-movable carriages 100, which have suitable vertical racks 101, as shown, and engaging these racks are the pinions 10i,which pinions 104 are mounted on a shaft 102, which is journaled in the main frames 11 and which may have a suitable hand-wheel 103. The second feeding-in roll 14 and the pressure-

rolls

13 and 16 are journaled in these vertically-movable carriages 100, and the remaining feeding-rolls are journaled in the main frames 11. By this means it will be seen that the web can be very readily threaded through this feeding-in apparatus by simply leading the same from the feeding-in roll 12 to the feeding-in roll 15 and then allowing the intermediate feedingin roll l-l and the pressure-

rolls

13 and 16 to descend into place. Of course as these

rolls

13, 14, and 16 are raised their gears will be also lifted out of mesh. The chief advantage, however, in this construction lies in the expeditious manner in which the whole press can be threaded, and it will be seen that when the feeding-inrollers are lifted, as before described, there is an open pathway through the feeding-in rolls, and that the web can be readily drawn through the same without turning the rolls.

The way my press can be threaded is as follows: The web is slacked off from the roll H to pass in through the feeding-in rollers, with the

rollers

13, 14, and 16 raised to allow an open pathway, and the web is properly led around the various guides to the deliveryrolls, into which the end of the web is threaded, so as to be tightly clamped. It will be seen that the web during this operation can be readily pulled off from the web-roll, as the continuously-runnin g feeding-in rolls will not hold or retain the web.

\Vhen the web has been properly threaded through the entire machine, the slack in the web in the machine may be taken up by turning theweb-roll H backward until the web has got sufficiently taut in the machine, when the

rolls

13, 14, and 16 are moved down to tightly engage the web at the feeding-in point. In other words, the slack is taken up backward. This is a great improvement in the way of threading up presses of this character, as the entire press can be threaded with all the parts stationary, and the web can be tightened up without even starting the press. It will be seen that the only change necessary in order to accomplish this desirable way of threading the press is to provide means to form a pathway through. the feeding-in rollers. This specific way of threading the press is shown, described, and claimed in the Stonemetz application, on which this application is an improvement, the improvement being that the feeding-in gearing is varied, so as to vary the length of the sheets.

A shaft is journaled in the frames 11 beneath the driving-shaft 42 and on this shaft are set suitable arms or levers 106, which levers 106 are connected by suitable arms 107 to the feeding-looper 17. The feeding looping-roller 17 is mounted in suitable bearings 109, which bearings are arranged so as to slide vertically in a suitable guideway 108, formed in the main frames 11. The levers 100 are also connected by means of suitable links or arms 110 to the looping deliveryroller 27. This looping delivery-roller 27 is mounted in suitable bearings 112, which are arranged so as to be vertically movable in suitable guideways 111, formed on the frames 11. By this means, as the levers 106 are vibrated, the two looping-rollers 1'7 and 27 will be oppositely moved up and down. The means by which these levers may be operated is as follows: On the shaft 42 are arrangeda series of cams, as 113, 114, and 115. These cams vary in size fora purpose hereinafter de scribed, and these cams are firmly keyed to the shaft 42. The shaft 42 is geared so as to make two complete revolutions for each forward and backward movement of the impression-cylinders, or reciprocation, whereby the paper can be properly fed forward when the impression-cylinders are off the form-beds in either direction.

Arranged on the shaft 105 are as many yokes 116 117 118 as there are cams on the shaft 42. These yokes have extending collars, as 124, and are all loosely mounted on the shaft 105 between the

collars

120 and 121, which are secured to the shaft 105. These yokes carry suitable studs 122 in the ends thereof, on which studs are mounted suitable rollers 123, which engage the cams, as shown. Each of the hubs 124 of the yokes has a hole drilled through the same, and a hole is also drilled through the shaft 105 in line-with these holes through the hubs 124, and these holes are made tapered, so that a suitable taperpin 125 may be inserted into the hub of any one of the yokes.

If the taper-pin 125 is not inserted into any one of the yokes, it will be seen that the cams will simply rock the yokes without imparting any motion to the shaft 105; but now if the taper-pin 125 should be put into the hole in any one of the hubs the particular yoke would impart motion to the shaft 105, and thus to the looping-rollers.

It will be seen that by taking the taper-pin out of one hub 124 and inserting the same in another hub of any of the yokes any cam can be made to actuate the looping-rollers. This means, acting in connection with the change-gearing before described, enables me to vary the size of the sheets. Thus, for example, the particular machine shown is organized to print either a twenty-inch, a

twenty-two-inch, or a twenty-four-inch sheet.

WVhen it is desired to change from one sheet to another, all that is necessary is to change the taper-pin 125 into the proper hub 124 and to use the proper gear 61, 010, or 611 in the chan ge-gearin g, as before described. By this mechanism the speed of the feeding-in rollers, the speed at which the continuously-running guide-rollers are moved, the speed at which the looping-out roller is moved, the speed at which the continuously-running deliveryrollers are turned, and the movement of the looping feeding-in roller will all be properly changed and set.

The speed of the cutting-cylinders will at all times remain a constant. Therefore I have organized a machine which can be very simply and quickly adjusted for the desired size of sheet.

Of course more than three cams or more than three sets of change-gears may be provided.

The cutting-

cylinders

33 and 34 in the peculiar device under consideration are designed so as to bear the relation of four to five, that is, the upper cutting-cylinder 33 will turn five times to the lower cutting-cylinder four times. These cutting-cylinders are run at a much faster speed than the continuously-running delivery-rollers, and thus for every four revolutions of the cutting-cylinder 34 a sheet will be severed from the end of the web, the end of the web lying on the tapes 35 will be coaxed forward, and the moment the sheet is cut from the web the same will be shot rapidly forward onto the foldingrollers and will be folded and delivered as desired. By this means I am enabled to longitudinally fold the sheets with a tuckerblade and get the same out of the way before the next sheet is ready to come into position. Also it will be seen that if the speed of the continuously-running delivery-rolls is altered, as before described, the action of the cutting-cylinders and folding mechanism will not be affected, the only change being a slight difference between the speed of the cuttingcylinders and the delivery-rollers.

Another way in which the speed of the continuously-running feeding-in and feeding-out rollers could be varied is by using various sizes of feeding-in or feeding-out rollers, and

other ways will suggest thenisel ves to a skilled I printing-press mechanic.

The use of a set of continuously-running cutting-cylinders in connection with means for varying the feed-out of the web in a machine of this character I believe to be broadly new.

The essence of this part of my invention lies in the fact that the cutting-cylinders travel at all times faster than the web, or at least as fast, and that they will thereby tend to coax or comb the end of the web forward.

The operation of the entire machine is evident from the foregoing description, an impression being taken both ways with the impression-cylinders and the web pulled forward when the impression-cylinders are oif the form-beds in either direction.

Thus it will be seen that I have improved the details and arrangements of parts, especially applicable to a press of the character referred to, and it will be seen that many of my improvements are applicable to'a press of that character, no matter whether a single cylinder is used in the same or a plurality of cylinders or in what manner the beds are arranged.

The details and arrangement of parts herein described may be greatly varied by a skilled mechanic without departing from the scope of my invention, as expressed in the claims.
