SPECIFICATION formng part of Letters Patent No. 590,604, datedseptember 28, 189'?. Application filed August 24;, 1893. Renewed March 18, 1897. Serial No. 628,222. No model.)

.To @ZZ whom it may concern.-

Beit known that I, HENRY A. WISE WOOD, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a new and useful Improvement in Printing-li/Iachnes, of which the following is a specification.

The aim of this invention is to improve that class of presses which are known in the art as reciprocating bed printing-presses; and it consists in the peculiar feeding or webmanipulating devices hereinafter described, and also of a perfecting form of such press.

The first part ofvmy invent-ion is applicable either to a single form of such press, in which the web is printed on one side only, or to a double form of such press, in which the web is printed upon both sides, and in the drawings I have illustrated both such arrangements.

Referring' to the drawings and in detail, Figure 1 is a side elevation of a printing-machine of the character referredto'with my improvements applied thereto. Fig. 2 is a sectional diagrammatic view illustrating the bed in the center of `its movement to the right or in impression. Fig. 3 is a view similar to Fig. 2, showing the bed out of impression at the right. Fig. 4 is a sectional diagram matic view'illustrating my improved reciprocating-bed web-perfecting press; and

Fig. 5 is a View similar to Fig. 4, illustrating a modification of the device shown in Fig. 4.

This invention consists, first, in providing a reciprocating or traveling bed web-printing press with a peculiar feeding mechanism which will continuously feed the Web into the press; also,whieh will preferably continuously feed the web out of the press, which will respace or shift the web around the impressioncylinder to perform the feed, .and also in the peculiar compensating device by which the movement of the web necessarily given during the printing operation will be compensated for. A

My invention further consists of a perfecting form of tra veling-bed Web-printing press so arranged that an impression can be taken on the web both at the forward and backward movements of the beds.

Referring to the device shown in the first three sheets of the drawings, 10 represent -the usual side frames of a machine of the character referred to.

B represents the traveling bed, which is mounted in suitable Ways or guides on the side frames, and A represents the stationary revoluble impression-cylinder with which the traveling bed coacts.

The cylinder and bed driving mechanism may be arranged inany of the desired ways common in the art. On the stationary frames 10 10 are secured suitable brackets 1111, in which form-rollers, as FF FF, and distributer-rollers G G may be arranged, so that the form placed upon the traveling bed B will receive the proper supply of ink, and ink may be given to the form-rollers by any of the usual mechanisms, as ink-tables or ink-fountains, not necessary here to show or describe at length.

Secured on the bed B is a rack 12, which meshes with a gear 13, secured on the shaft 14 of the limpression-cylinder A. This gearing may be mounted on both sides of the impression-cylinder, if so desired. Also mounted on the shaft 14 of the impression-cylinder A are two gears or piuions 15 15, whose pitch diameters are one-half the diameter of the impression-cylinder. These gears or pinions l5 mesh with and engage racks 16 of the sliders 17, which are mounted so as to be capable of a horizontal movement on the main frames 10 10. These frames carry loopingrollers 18 and 19 at their outer ends, as shown, around which the web is looped in opposite di-y rections by the guides hereinafter described. By this means it will be seen that the looping- rollers 18 and 19 will move oppositely to the bed B and at one-half the speed thereof.

A guide, as 20 2l, is arranged at each side of the stationary impression-cylinder, as shown. The path of the web through the machine may be followed by reference to Fig. 2.

From the Web-roll W, which may be mounted at the end of the frames, the web is led in between the bite of the rollers 22, 23, and 2.4. These rollers are preferably continuously driven, as by the means hereinafter described, and therefore will serve as and constitute afeeding mechanism adapted to continuously draw the web from the web-roll and feed the same to the machine. From these continuously-running rollers the web passes under the looping-roller 25, as shown, then up over the guide-roll 2G, which is journaled in the main frames lO, then around the horizontallymoving looping-roller 1S, before referred to, then around a roller 27, which is journaled in the main frames 10, over the guide 20, under the impression-cylinder A, over the guide 2l, then around a guide 2S, which is journaled in the main frames 10, then around the horizontally-moving looping-roller 19, before referred to, and then around a roller 29, which is journaled in the frames l lO.

From the roller 29 the web passes around the looping-roller 130, and the ltwo loopingrollers and 30 are operated, as by the mechanisms hereinafter described, so as to constitute a shifting mechanism which will shift or feed the proper length of web around the impression-cylinder A while the same is not in impression with the form, so that at the next printing movement of the bed a fresh surface of the web can be printed.

From the looping-roller 30 the web is led out of the machine between the continuouslyrunning rollers 3l, 32, and 33. These rollers are continuously driven, as by the gearing hereinafter described. It will thus be seen that these rollers serve as a feeding-out mechanism which will continuously feed the web out of the press. The gearing for operating' these various parts, before referred to, may be arranged as follows:

34 represents the driving-shaft, which may be suitably journaled in the main frames lO lO and to which power may be applied by any suitable means, not necessary here to describe at length.

Mounted on the shaft 34 is a pinion 35, which meshes with and engages a gear 3G, which is mounted on a shaft 360, journaled in the main framing, as shown. Also mounted on the shaft SUO are crank-disks 361, which carry crank-pins 37, and these crank-pins connect by pitmen or connecting rods 3S to a shaft 39. This shaft 39 may be journaled in bearings 40, which are fitted in suitable ways 4l in the main frames, as shown. On this shaft 39 are arranged two gears 42, which mesh with and engage stationary racks 43, secured on the inside of the main frames, as shown.

Fastened on the under side of the bed B are racks 44, into which the gears 42 mesh. One gear 42, arranged in the middle of the press, may be used, or two gears arranged near the side frames may be used. By this means it will be seen that the bed B, as the partsare operated, will besmoothlyand easily reci procated.

Meshing with and engaging the gear 3G is a gear 45, which is mounted on a suitable stud 4G, mounted in the main framing. Meshing with and engaging this gear 45 is a gear 47, which is mounted on a suitable stud or short shaft 48, journaled in the main framing, as shown. On the outside end of this shaft 48 is mounted a bevel-gear 49, which meshes with and engages a bevel-pinion 50, which is secured to the shaft 51, which shaft 5l is journaled in suitable bearings 52, secured to one of the frames 10, and which shaft 5l extends nearly the entire length ofthe press, as shown. I use this shaft to drive the continuously-ru n ning feeding-in and feedingout mechanism, and the gearing may be arranged as follows: On the left-hand end of the shaft 5l is mounted a bevel-gear 53, which meshes with a bevel-pinion 55, mounted on the lower end of the shaft 5G, which shaft 56 is vertically arranged and journaled in suitable brackets, as 54 and 57. On the upper end of this shaft 56 is mounted a bevel-pinion 5S, which engages and meshes with a bevel-pinion 59, mounted on the end of the feeding-in roller 23.

The feeding-in roller 22, 23, and 24 are geared together, so that as the middle roller is turned they will all be revolved together. By this means the feeding-in device is rendered continuous.

On the right-hand end of the shaft 5l is mounted a bevel-gear 60, which meshes with and engages a bevel-gear 62, secured on the lower end of a vertically-arranged shaft G3, which shaft 63 is journaled in suitable brackets Gl and 64, secured to the frame of the machine. On the upper end of this shaft (i4 is mounted a bevel-pinion G5, which meshes with and engages a bevel-pinion (S6, secured to the middle feeding-out roller 32.

The feeding-out rollers 3l, 32, and 33 are geared together, so that as the middle roller is revolved they will all revolve synchronously. By this gearing the feeding-out device is rendered continuous.

Meshing with and engaging the gear 47 is a gear G60,which is mounted on a shaft (57,which shaft 67 is journaled in the main frames, as shown.

The gear GGO is made one-half the size of the gear 3G, so that the same will turn twice for every forward and backward movement of the bed B. Mounted on this shaft 67 are cams GS.

69 represents suitable yokes,wl1ich are preferabl y hun g on the shaft 67, and which yolzes carry rollers 7 0 and 7l, which en gage the cam 68. Extending from the yolies (59 are arms 690 and 991. The arms 690 connect to bellcrank levers 75,which are mounted upon studs 7G. The arms G91 of the yokes 69 connect to suitable bell-crank levers '72,which are mounted upon studs 7 3, as shown. I preferably use two cams GS on opposite sides of the press and two yokes, and such is the arrangement shown. However, if desired, one cam and one yoke could be used, and instead of using studs 7G and 73 shafts could be used, which could be made to extend across the press, and on which shafts the arms which operate the ICO IIO

looping-rollers could be secured, and of course the gearing could be so arranged that this could be done.

The ends of the bell-crank levers 75 connect to arms 77, which constitute alooping-frame, and which arms are suitably guided in the main frames.

The bell-crank levers 72 connect to suitable arms 74, which constitute a looping-frame, and which arms 74 are suitably mounted in the main frames.

The looping feeding-in roller 25 ismounted in the arms 77, and the looping feeding-out roller 30 is mounted in the arms 74. By this means it will be seen that the looping- rollers 25 and 30 willbe oppositely moved up and down. improved means for operating one or two looping-rollers. By this gearing and means described it will be seen that the press may be properly operated.

In Fig. 2 the bed B and cylinder A are shown as in impression and the bed as moving to the right.

The web is looped horizontally at each side of the impression-cylinder around the horizontally-moving looping-rollers18 and 19, as shown. As the bed moves to the right these looping- rollers 18 and 19 will move to the left, and as they move at one-half the speed of the bed the proper amount of web will be paid out and allowed to run around the impressioncylinder A, so that the web around the impression-cylinder A will move in unison with the bed B.

The web which is continuously drawn from the web -roll by the continuouslyrunning feeding-in rollers is taken up by the loopingroller 25, and the web which is being fed out of the press by the continuous]y-running feeding-out rollers is being supplied by the upward movement of the looping-roller 30. In other words, during the printing movement of the bed there is no advance of the web into or out of the printing district proper, which dis trict is bounded by the guide 26 on the one hand and by the guide 29 on the other hand. Now when the bed B moves out of impression with the cylinderA the looping- rollers 25 and 30 will be oppositely moved-that is, the looping-roller 25 will move upward and the looping-roller 30 will move downwardand, as shown, the looping-rollers are timed so as to have an equal upward-and-downward movement. This can be done by using a heartshaped cam or cams. Thusthe feeding or re` spacing of the web with regard to the printing mechanism takes place.

The bed B is shown out of impression in Fig. 3. In this case the web fed into the press by the continuously-running rollers and the upwardly-moving looping-roller 25 is being drawn forward or shifted around the impression-cylinder A by means of' the downward movement of the feeding-out roller 30 and the This gearing constitutes a new and der a fresh portion ofthe web will be printed. p

The action of the looping- rollers 18 and 19 may be said to be that of a compensating feeding mechanism-that is, it is a feeding mechanism which simply moves or adjusts the web around the impression-cylinder to compensate for the movement of the bed, as to make proper printing the web has to move during the impression at the same speed as the bed. This horizontal disposition of the loopingrollers presents a very neat, simple, and positive compensating feeding mechanism. s

By the feeding mechanism before described it will be seen that the web is continuously fed into and fed out of the press, that the movement of the bed is compensated for by properly moving the Web, and that the web is delivered from the printi'ngdistrict, which is bounded by the guides 26 and 29, while the impression-cylinder is out of printing contact with the form.

As shown, the bed is arranged so as to print both on its forward and backward movement,

` and although it is within the scope of my invention to make the bed print only on one movement and to operate the members so that the other movement of the bed will not make an impression it is preferred to make an impression both ways. Thus I have invented a very fast acting web-printing press.

My invention is of course applicable to a printing-press in which two traveling beds are used, and such au arrangement is shown in Figs. 4 and 5. In Fig. 4 I have shown two beds, as B B', arranged one above the other and as geared together through the gear or gears on the impression-cylinderA, and avrack or racks 121, secured to the under side of the bed B. By this mechanism the beds B and B will move oppositely,but in the same timethat is, the forms on the beds will be in impression at the same time and out of impression at the same time. The path of the web through this arrangement of the press may be arranged as follows: From the web-roll NV the web passes in through the continuouslyrunning feeding-in rollers 100, 101, and 102,

which serve to continuously draw and feed the web into the press. Then the web passes under the looping feeding-in roller 103, then up over the stationary guide-roller 104 to the stationary guide-roller 105. Then the web is looped around the looping-roller 106. Then the same passes to the stationary guide-roller4 107, under the impression cylinder A, up

around the guide-roller 108, then around the guide-rollers 109 and 110 to the upper press.

Either or both of the guide-rollers 109 or 110 may be. made adjustable in any of the usual manners to secure register of the web between the two presses.

Continuously-runnin g feeding-out rollers 31, From the guide-roller 110 the web passes to IOO IIC

the stationary guide-roller 111, then under the impression-cylinder A', then over the guide-roller 112 to the stationary guide-roller 113, then around the looping-roller 114, then to the stationary guide-roller 115 up over the looping-roller 116, and then out of the press through the rollers 117, 118, and 119. These rollers 117, 118, and 110 are continuously driven, so as to continuously deliver the web from the press. It will be noted that the web is oppositely looped around the looping- rollers 114 and 106; also, that the looping-rollers are actuated, as described in the previous device,from the reciprocating frames 17, and the lower looping-roller 106 may be mounted in suitable arms or brackets 120, extending from these frames 17. bed B' carries a rack or racks 122, which mesh with a gear or gears secured on the sides of the impression-cylinder A', similar to the gear or gears 13 of the previous device.

1 23 represents the driving-shaft,from which power is applied by means of pinion 124 to the gear 125, mounted on a shaft 126, and this shaft 126 may carry crank-pins 127, similar to crank-pins 37 of the previous device, by which the beds will be actuated. It will be seen, as before stated, that the beds will be oppositely moved. This arrangement of beds is substantially the same as that shown in the patent to Royal Cummings, No. 83,471, granted October 27, 1868; but my invention embraces an important improvement over what is shown in his patent in that by the use of my invention I am enabled to print both on the forward and backward movements of the beds and by which I am enabled to continuously feed the web into and out of the press, whereby the capacity and production of the press will be more than doubled.

The looping-rollers 103 and 116 may be mounted in suitable arms 132, which arms may carry suitable rollers 131, which may bear upon cams 130, mounted on a shaft 129, which shaft 129 may be driven from the shaft 126, as by means of the gears 125 and 128.

The gear 128 is preferably made one-half the size of the gear 125, whereby the cams 130 will turn twice for each forward-andbackward reciprocation of the bed.

The rollers 131 are preferably held against the cams 130, as by means of springs 133.

The action of the press thus far described is substantially the same as that of the previous device, except that instead of the web being printed on one side the same will be printed upon both sides or perfected. It is not necessary that the beds should be arranged one directly over the other, as they can be arranged in many different ways. One of such different arrangements is shown in Fig. 5, in which the beds are shown as arranged in the same horizontal plane, end to end.' In this modification the web is slacked off from the web-roll XV and fed into the press The upperV between the four continuously-running feeding-in rollers 201, 202, 203, and 204. Then the web passes around the looping-roller 205, around the stationary roller 206, then around the compensating looping-roller 207, then around the stationary roller 208, then to the middle of the press, around the roller 200, up over the guide 210, then around the guide 211, under the impression-cylinder A, around the guide 212, back to the guide or roll 213, then under the impression-cylinder A', then up around the guide-roll 214, then to the guideroll 215, then down under the compensating looping-roller 216, then around the stationary roller 217, around the looping feeding-out roller 218,and then between the continuouslyrunning feeding-out rollers 219, 220, and 221. These rollers 210, 220, and 221 are continuously driven to positively and continuously feed the web out of the press. By this passage of the web it will be seen that the same will be printed and perfected substantially as before described.

The mechanism for driving these various parts may be arranged as follows: 223 represents a driving-shaft which is geared by pinion 224 to a large gear 225. This large gear 225 carries a crank-pin 226, which crank-pin 226 has mounted thereon a block 227, which engages a vertical slot of the slider 228, which slider 228 is mounted so as to be capable of ahorizontal movement. This slider 228 may also be mounted, if desired, upon a block secured upon the shaft 232 of the gear 225. This yoke 228 carries a rack 229,which meshes with anintermediate 230, which intermediate 230 meshes with a gear 231, which gear 231 meshes with a rack 44 of the bed B. The yoke or slider 228 also carries a rack 233,Which meshes with a gear 234, which gear 234 meshes with and engages the rack 222 of the bed B'. By this means it will be seen that as the shaft 223 is rotated the slider 228 will be reciproeated and the bed B will be moved or reciprocated in opposite directions. To operate the compensating looping device, which consists of the looping-rollers 207 and 21o, I mount gears 235 with the gear 234. These gears 235 mesh with segments 236, which are mounted on a shaft 237. These segments connect by connections 238 to bell-crank levers 239, which are mounted on a shaft 240, and this shaft 240 has suitable connections to the looping-frame 241, which carries the looping compensating rollers 207 and 216. By this means it will be seen that the compensating looping-rollers will be properly actuated so that the web will be properly moved around the impression-cylinders to compensate for the movement of the beds. The webshifting looping rollers 205 and 218 are mounted in a suitable frame 245, which frame has rollers 244, which engage cams 243, which cams are mounted on a shaft 242, which is driven from any suitable part of the mechanism twice for each complete reciprocation IOO IOS

IIO

of the beds. Springs 246 are preferably used to keep the rollers 24e against the cams. By this means the looping shiftin g-rollers will be properly actuated. Thus this mechanism will perfect a web, making two impressions for each forward-and-backward movement of the beds. I may use either a single yoke 228 and a single set of gearing to drive the -beds in opposite directions, but itis preferred to use a double set of yokes, one near each side frame, and a double set of gearing to drive the beds. In these last two described devices it will be seen that the two impression-cylinders will rotate oppositely, whereby the web can always properly run from one impressioncylinder to the other without any intermediate device being` interposed in the path of the web between the two impression-cylinders. Thus it will be seen that I have greatly improved the class of presses known in the art as traveling-bed presses, and my improvements consist, so far as the web-controlling devices are concerned, first, in providing a continuous feed-in of the web,` and so far as this continuous feed-in is concerned any delivery mechanism can be used in connection with the same without departing from the scope of the claims; second, in providing a.

continuous feed-out or delivery for the web, and so far as this feed-out is concerned any feeding-in mechanism can be used in connection with the same without departing from the scope of the claims; third, in providing a horizontally-arranged compensating looping device consisting of two synchronouslymoving looping devices. A

I do not wish to be limitedto the details herein shown, as many equivalent devices for the feeding mechanisms are known and can be used and substituted by a skilled mechanic without departing from the scope of my invention as expressed in the claims.

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