T 0 all] whom it may concern:

Be itknown that I, Hu NRY A. l/VISE 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 Rotary Web-Printing Press, of which the following is a specification. a

The aim of this invention is to improve the parts and operation of printing-presses, and especially relates to improvements in the inking apparatus thereof by which a very simple distributing apparatus is provided in which the composition rollers may be very easily placed in position or removed and in which the distribution is perfect. I have further improved the inking apparatus by providing means so that different qualities or colored inks may be supplied to the same distributing apparatus. 1 have further improved the inking apparatus by providing means whereby the ink-distributing apparatus can be kept at a constant temperature.

Referring to the accompanying three sheets of drawings, 1 have shown enough of one form of printing-press to illustrate how my improvements may be applied to the ordinary rotary web-printing press.

Referring to said drawings, Figure 1 is a 'side elevation of a printing-machine con-' structed with my improvements. Fig. 2 is a sectional elevation thereof. Figs. 3 and a are a sectional and side elevation, on an enlarged scale, of a detail of the inking apparatus; and Fig. 5 illustrates a modification hereinafter referred to at length.

Referring to the drawings and in detail, A designates the usual framing of the machine. B designates the first printing-cylinder; C,

, the first-impression cylinder; D, the secondimpression cylinder, and E the second printing-cylinder. These printing-couples are arranged and geared in any of the usual ways, so that if a web is led through the same the-web will be printed on both sides, or perfected.

W designates the web-roll, which-is mounted in the framing in any of the usual manners and from which the web we is led around a drum 10, which is continuously driven by any suitable gearing, as by an intermediate from cylinder B. Coacting with this drum is a set of tapes 11, which bear on said drum and which are led around the tape-pulleys 12, 13, and 14, as shown. The shaft that carries the tape-pulleys 13 may be mounted in eccenadjusted to any desired degree.

tric boxes 15, which have suitable operatinghandles 16, as shown, so that by adjusting these boxes the tension of the tapes may be in some instances instead of using a set of tapes 1' may use an endless belt. The drum or rol'l lO and the tapes are positively rotated to positively draw the web from the roll and'forward the same into the bite of the first printing-couple.

rom the last printing-couple the-web may be led around suitable rollers'l T, l8, and 19 to any suitable foldirlg device, as F.

I will now describe the details of my improved inking apparatus, and as the same construction is used in connection Wi'th'each printing-couple adescription of that used in connec tion with the first printing-couple will sufiicc.

G G represent two ink-fountains of any of the usual constructions.- These fountaiushave the usual ink drums or rolls 20. 'rh'ese ine fountains are arranged on a suitable plate or base 21, which is fitted to slide 'in suitable ways 22, fopmed in the framing. A shaft 23 1S journaled in the frames under the base and carries pinions 24, which mesh with racks 25, secured to the base 23 may be provided with a squared head, and a suitable handle 26 'i'nay be arranged to fit thereon. By this construction the base 21 may be moved forward 'or'bz'tckward in the framing and either fountain Cr or G brought into operative position.- Theshafts 27 of the fountaiu-rollers'20 project through the sides of the fountain-casings, as shown in Fig 3, and the'back ends of the same are provided with suitable squared or broached soclretsQ/ZO. A quill or bushing 28 is journaled in the frame, as shown, and has formed or fastened on the end thereof a 'ratehetwheel 29. The

quill is kept'in place by means of collars 2.80 and 281. Hung on said quill 28'is a lever 30, which carries a spring-pressed pawl 31 for en gaging the ratchet-wheel 29. This lever is vibrated by a suitable link or connection 32, which is connected to any of the moving parts of the mechanism in the usuai manner.

The lever 30 is provided with a slot, so that the link or connection 32 may be adjusted on the lever 30 so thattli'e ratchet-wheelmay be turned more or less,'as de'sired. Insorne instances I contemplate using the ordinary holding-ratchet in connection with the ratchetwheel... A shaft'33 is fitted in'the quill 28, as shown, and this shaft is provided with a The end of, the shaft .41 and 42 is a composition roller 45. ranged between the distributing- drums 42 and 43 is another composition roller 46. Ar

key 34, which fits in a slot 35, cut in the quill 28. The end of this shaft 33 is provided with a suitable button or knob 36. A collar 37 1s fitted on the shaft 33 near the inner end thereof, and a spring 38 is arranged betwe n this collar and the shoulder formed in the quill, as shown in Fig. 3, so that the shaft 33 is normally held in its innermost position. The end of the shaft 33 is squared. as .shown at 39, to fit into the socket 270 in the shaft 27 of the drum-roll 20. By this construction by pulling out the shaft 33 by means of the butten 36 and by manipulating the handle 26 either fountain G or G may be brought into operative position. By arranging a plurality of fountains in this manner a very advanta: geous resultis obtained, in that different q ualities or'colors of ink can be used in the same machine. If different quality of ink is desired, it is simply necessary to bring another fountain into operative position.

If a different-c0lored ink is desired, all that is necessaryis to move the proper fountain into operative position and clean the distributing system or rollers. This can be very easily done.

In the ordinary construction where a different-colored ink is desired it is necessary to clean out the fountain and then put in the diiferent'eolored ink. It is a hard, diflicult, slow, and dirty task to clean an ink-fountain. so that a dilferent-colored ink can be placed therein. By the use of my improved device I dispense with all this trouble.

I contemplate in some cases using more than twofount-ains and so arranging the same that any fountain can be brought into operative position as desired.

This i mprovement is very advantageous in multideck-presses where it is desired sometimes to run a colored supplement, so that one web may be led through the machine and printed in color. A modification of ink-fountains to obtain this result is shown in Fig. 5. In this modification the two ink-fountains (i and G are secured rigidly in the framing. Double-armed levers 40 are arranged so that the ductor-roll 410 can be placed in either arms thereof. In this construction only that fountain is operated with which the ductorroll coact su The ductor-roll levers are ar ranged on a suitable shaft 40, which is oscillated by any of the usual mechanisms, so that the ductor-roll will take ink from the drumroller 20 of either fountain and deposit the same on the first distributing-roller 41.

42, 43, and 44 designate the subsequent distributing rollers or drum.

Arranged between the distributing-rollers ranged between the drums 43 and 44 is another composition roller 47 and arranged between the distributing-drum 44 and the printing-cyl- It will'be noted that the drum-cylinders .or

distributing- rollers 41, 42, 43. and 44 are of different sizes. The preferable arrangement is to make them of increasing diametersthat is, for example, the distributing-roller 41 maybe five inches, the roller 42 may be six inches, the roller 43 may be seven inches, and the roller 44 may be eight inches. In this arrangement the circumferential distribution of ink is perfect, so that the ink which is placed upon the distributing-roller 41 in a lump, as it were, will be subsequently broken up and spread by the cylinders of varying diameters. In otherwords, as the cylinders do not register, the ink is effectually broken up and spread, and this is a much better operation than the common practice where the drum-cylinders are of the same diameter. I preferably vibrate two of the distributingrollers, as 42 and 43, by any of the usual mechanisms not necessary here to show. It will be seen that this construction I-obtam a perfect distribution by but six composition rollers and a distribution which I believe is the best of any device yet devised, due to the varying andincreasing diameters of the drumcylinders.

-Another difficulty which arises in inking apparatuses as today constructed is that when the press is first started the ink is very hard and slow; but after the press has been run for some time the drum-cylinders will become hot, and then the distribution of ink will be very fast. This is one of the points that limits the speed of presses torday. Further, in many press-rooms that have been unused through the day thetemperature falls and when the presses are started the ink is hard and unyielding. bringing great strain onthe rolls and general mechanism of the press, besides giving a product that is gray and not black. After the pressis started and warmed up, if the press is run at such a speed as to unduly heat the distributing-rollers, the form or composition rollers will be distorted'orspoiled and the press necessarily disabled.

To keep the drum-cylinders of the inking apparatus always at a proper temperature, I provide means for circulating cold water through the same and also means by which the wa er can be heated to bring the inking apparatus to the proper temperature, so that the press will easily start in proper operation; One way I may accomplish this is to mounta suitable tank, as 50, on the press-frame and provide the supply of water passing the same with a suitable water-supwhich may have a ball-cock valve-52. the tank will be always kept full of A pipe 53 leads from the tank and p y so that water.

connects by branches 54 to each set of distributing devices.

The water is first carried in through one journal of the distributingroller 44, then by a suitable branch pipe 55 through the distributing-roller 43, then by a suitable branch 56 through the distributingroller &2, and then by a suitable branch 57 through the distributing-roll 41, and thence by a suitable pipe 58 to the sewer or back to the tank by any suitable pump. Suitable valves, as 59, are provided in the pipe system that extends to each inking apparatus, so that through each inking apparatus can be regulated. A suitable heating apparatus, as a gas-pipe 60, provided with a suitable number of jets 61, is arranged in connection with the pipe-line, as shown in ig. 2. This gaspipe is provided with a suitable valve 62. Before thepress is started in operation this heating device is used, and hot water is thus first circulated through the ink-distributing apparatus. This will bring the ink-distributing apparatus to the proper temperature, so that when the press starts in operation the ink can be very evenly and accurately distributed, and by thismeans the parts can be very easily started in operation at full speed. After .the press has been operated for a short time the heating device is cut out, and then the proper amount of cold water is circulated through each distributing. apparatus, and this will overcome the heat generated by the friction of .the parts and will keep the ink-distributing apparatus at a proper temperature so that the press can be run at a very high rate of speed.

By these improvements 1 am enabled to greatly improve the operation of rotary webprinting presses.
