i Appieati'on liled October l,

T0 all Lu/tom, t `ivi/tty carl/cern.'

Be it known that I, HENRY A. WISE WOOD,

a `citizen of the .United States, residing at -lowing is a specification.

The aim of thisin vention is to improve the tra velingcylinder web-printing press; and to :this end the invention consists of the devices described and claimed in this specification and illustrated in the accompanying iive sheets of drawings, in whichy Figure 1 is a plan view of a printing-press with my impro vements applied thereto. Fig.

2 is a sectional elevation of the press shown in Fig. -l. Fig. 2u is a view showing a modiiication. Figs. 3 and 4 are diagrammatic views similar to Fig. 2, showing the operating Fig. 5 is a similar sectional view illustrating a web-perfecting form of tra veling-cylinder printingpress with my improvements applied thereto. lEig. 6 is a view similar to F ig. 3, illustrating a modification; and Fig. 7 is a diagram illustrating the action of the web when certain of my devices, as hereinafter described, are not used.

The especial aims of my invention are, first, to `provide devices whereby the web will be handled more easily in a traveling-cylinder or traveling-cylinder perfecting-web press, and, second, to provide improved inking devices.

4In web-printing presses as now organized and used the rapid reciprocation of the cylinder or cylinders causes an air-pressure in front of and asuction behind the moving cylinder. This action is illustrated in Fig. 7, in which an impression-cylinder is shown moving to the right over a stationary bed. In this case the web to the right of the cylinder will be bellied in between the guide 17 and the cylinder and will be bellied out between the guides 17 and 18, as shown. The web to the left of the cylinder will be sucked away from the cylinder between the guide 16 and the cylinder and will be sucked down between the guides 15 and 16,` as shown. This strain on the web due to the air-pressure and suction caused by the rapid movement of the cylinder, is very objectionable in practice. The reasons for this are that when the press Specification of Letters Patent.

is run at a high rate of speed the webis aptto be broken from this cause, especially if a weak place or splice occurs inthe web, and that the tendency of the same is disarrange the register between the -two impressions in a web-perfecting press. To remedy these evils, I have rprovided parts which I term wind-shields or guards, which I place in such relative positions with respect to the exposed portions of the web as to tend to prevent the web being bellied out or pulled in by air pressure or suction.

The second part of my invention consists in a peculiar inking device embodying moving ink-distributing tables.

Referring now to theiirst three sheetsof drawings, Ihave showntherein a single-cylto effect and inder web-printing pressfembodying my-lm-`vr provements.

Referring to ythe drawings vand in detail, A A represent .the side framesfof the machine, between which is mountedl or arranged in any of the usual mannersthe stationary bed B, upon which the form or forms canbe secured.

lG G represent two reciprocating carriers, which constitute a traveling carriage. lMounted in this carriage is an impression-cylinder l C, vwhich is adapted to coact with therform or forms on the bed B, so as to make an impression on either or both its forwardorbackward movements. Onev or more form-rollers F F are mounted in the reciprocating carriage at each side of the impression-cylinder lO, and a distributer E is preferably arranged to coact with each pair of form-rollers. A single-form roller of course could-'be used at each side of the impression-cylinder. At each end of the stationary bed is mounted an inking device. Each inking device consists, preferably, of four ink-tables L, L', L2, and L3, the ink-tables L and L3 being arranged stationary in the side frames and the two inkingtables L and L2 mechanism whereby they will be laterally reciprocated to nicely distribute the ink. Arranged .beyond each of these sets of inkingtables is a fountain I-I, which may be of any of the usual constructions and which may haverthe usual spreading or carrying roll h. The carriers G, constituting the reciprocationcarriage, are extended and carry therein on each side one or more distributer-rollers F2 being arranged and having Y roc IOS

F2 F2 F2, as shown in the drawings. As the carriage is reciprocatd these distributer or carrier rollers take the ink from the fountain H and spread the same on the inking-tables, where the ink is nicely distributed by the peculiar action before described, and from the ink-tables the ink is taken by the formrollers F F and spread nicely and e venly upon the form or forms. By this mechanism I have provided a very simple and efficient inking mechanism whereby very delicate and perfect printing can be done by reason of the large and accurate distribution.

The path of the web and the mechanism d for driving the various parts may be arranged as follows: The impression-cylinder may carry gears which may mesh with stationary racks mounted on the bed in the usual manner, so that as the cylinder is reciprocated the same will roll to register with the form or forms. The web may be led from a roll W, which may be mounted in any of the usual ways. The web w from the roll is first led in between the continuously-running feeding-'in rollers 10, 11, and 12 or any of the continudriven by any of the usual the feeding-in rollers the webis passed around a looping-in roller 13, which may be mounted in suitable arms 14 in guides in the side frames. From the feeding-in looper the ,web passes around avstationary guide or roll rollers 20, 21, and 22 or any of the usual continuously-running feeding-out devices which may be positively driven by any suitable mechanism not necessary here to describe at length. The arrangement of this feeding mechanism is well understood and is so proportioned and designed that the web will be held stationary while the cylinder is in impression and so that the web will be shifted or fed forward while the cylinder is out of impression at either end of the bed, the web being fed continuously into and out of the press.

The arms 23 and 14, that connect to the loopers, may be connected to common arms 24, which may be mounted on a shaft 240 in the main frames A and A. These arms 24 have studs 25 secured therein, which studs carry rollers 26, which bear on cams 27.

Springs 410 are connected to one end of the arms 24 and stationary parts and serve to keep the rollers 26 on the cams 27.

28 designates a shaft which, if desired, may be the driving-shaft of the machine and which has suitable tight and loose pulleys P and P mounted thereon. Power from the driving-shaft 28 is taken by means of pinions 29, mounted thereon, and gears 290, mounted on the cam-shaft 35. f'

3() designates a shaft which is connected to actuate the impression-cylinder. This shaft is driven from the cam-shaft 35 by means of bevel- gears 34 and 33 and parallel shaft 320 through the bevel pinion and gear 32 and 31, as indicated. If desired, the shaft 30 may be the shaft to which power is primarily applied, and the driving-shaft 28 may be arranged so that its pinion will mesh with the gears 290, which are then placed on the shaft 30, as indicated in dotted lines. This last construction is used where it is desired to reciprocate a` very heavy carriage. On the outside ends of the shaft 30 are mounted cranks 36, which connect by links or pitmen 37 to pivoted levers or arms 38, which are mounted on a shaft 40, secured in the main frames. These vibrating arms 38 connect by links 39 to the impression-cylinder C or to the carriers G, whereby the impression-cylinder will be reciprocated over the form-bed. On the other end of the shaft 320 is mounted a ruiter-gear 41, which meshes with a mitergear 42, and turning with the miter-gear 42 is a gear 43, which meshes with a gear 44,se cured on a shaft 45. Mounted on this shaft 45 is a boX-cam 46, having a groove 47.

48 designates a pivoted arm or lever which has a roll 49 engaging the groove 47 of the cam 46, and by this vibrated back and forth.

The tables L and L2, as before described, are mounted in the side frames, so as to be capable of lateral movement. connects by a link 50 and by an adjustable connection 51 to a long rod or link 52, which is used to vibrate the movable inking-tables and which may be also used to operate the ink-fountains. This arm connects at each end to a lever 53, which has the usual pawland-ratchet connection to the ink-supplying rolls H of the ink-fountains. The vibrating tables L have short racks 54, and the vibrating tables L2 have short racks 55, with which mesh toothed segments 56 and 57, which are mounted on studs depending from the stationary tables L. These sectors are given a short vibration by means of a short link and connection 58 and 59 to the link 52. By this mechanism as the link 52 reciprocates the inking-rollers of the fountain are turned and the movable ink-tables are reciprocated laterally, so that the ink will be nicely distributed and spread, as before described.

To prevent the rapid reciprocation of the impression-cylinders from bagging or stretching the web, I provide wind-shields, which are arranged very close to the web. The

IOO

The arm 48 IIO particular wind-shields shown in the drawings are constructed as follows: A number of rods, as the four rods 60, are carried across the press between the side frames and carry a thin shield or guard 61, which is arranged between the guides 15 and 13, as shown, and which may be arranged to bear directly upon or may be arranged at a very slight distance above the web. Between the roll or guide 1.6, carried by the carriage, and the bottoni of the impression-cylinder I arrange a metallic guard or shield 62, and between the roll or guide 17 and the bottom of the impressioncylinder I arrange a similar guard or shield 63. As the cylinder is reciprocated these guards or shields will prevent the web from ballooning or being stretched from the air pressure or suction and are intended to add greatly to the rapid operation of the press.

The impression-cylinder C has a gap or depression c3, in which may be mounted a set of grippers c2 and a reel c, by which a tympan or blanket c can be tightly stretched around the periphery of the impression-cylinder. A portion 0f the impression-cylinder is also cut away, as at c4, on each side of the depression c3. If preferred, the gap or depression may be made larger than shown, thus dispensing with the cut-away portions, which are formed at each side of the depression. This cut-away portion of the impression-cylinder cL and the depression c3 are so arranged relatively to the impression peripheral surface of the impression-cylinder that when the impression-cylinder'is moved so that the same is off the form in either direction, as indicated in Figs. 3 and 41, the web will not touch the impression surface or cylinder, being held therefrom by the lower ends of the wind guards or shields 64 and 63. By this means when the shifting of the web around the impression-cylinder takes place the web will be shifted without rubbing or bearing on the impression-surface and will also be raised away from the surface of the ink-tables L3, whereby the web is fed about the impression-cylinder while the same is over one of the ink-tables and so held that it will not be blurred or smeared by contact either with the impression-cylinder or the ink-table.

In Fig. 5 I have shown a sectional elevation embodying a perfecting form of a printing-press arranged to have the improvements before described. In this press an additional bed B and impressioncylinder C are used. The loopers 13 and 19 are mounted in common arms 130, which may be actuated by cams in any of the usual manners. The inking apparatus is arranged, as before described, for each bed B and B, and the wind guards or shields are arranged about the web, as described. From the first iinpression-cylinder the web passes around the stationary guide or roll 70, beneath the adjustable register-roll 71, up over the stationary guide or roll 72, then to the guide or roll 75, carried by the carriage, under the second impression-cylinder C, then around the guide or roll 76, also carried by the carriage G, to the feeding-out device. This path of the web will enable the same to be perfected. If desired, with this mechanism I can arrange a wind guard or shield at the right of the press between the guides or rolls and 72, and the same may consist of a thin metallic shield or guard 74, carried by the cross-rods 73 73. The operation of the parts in the perfecting form of the press is substantially the same as that in the singlecylinder press, and it is thought that a specific description of the same is not necessary.

In Fig. 6 I have shown a modification of the wind-shield that is used' above the impression-cylinder. The guard instead of consisting of a thin metallic shield or frame is made .in the form of an endless belt 103, which may be made out of stiff or heavy canvas and which is turned around the rolls 100 and 101, mounted in the frames, as shown, and which has its ends connected to the carriage, as by rods 104. With this modification as the cylinder reciprocates the endless. belt will run back and forth and will form a shield, which will prevent the web from bellying or ballooning out by the air pressure or suction.

In some cases instead of arranging the wind-shield above the web to prevent the same from ballooning I may arrange the shield between the web and the cause of the pressure-that is to say, in the arrangement shown I may arrange the shield below the web,. and such an arrangement is clearly within the scope of my invention. This arrangement is shown in Fig. 2a, the windshields 610 620 being made of sheet metal and secured in the carriage. The free ends of the same pass over rollers 611, so that said shields will reciprocate with the cylinder.

I am aware that many of the details that I have herein described may be applied by a skilled mechanic to other forms of presses, and the particular arrangements and relative locations of the cooperating elements may be greatly varied by a skilled mechanic and still accomplish the functions I have described.

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