INKING AP PARATU S.

SPEUIFICATION' forming part of Letters Patent No. 701,119, dated May 27, 1 902.

Application filed March 4, 1898. Renewed October 12, 1901. Serial No. 78,50 (No model) To all whom it may concern:

Be it 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 5 of New York, haveinvented a new and useful Inking Apparatus, of which the following is a specification.

The aim of this invention is to improve inking apparatus, especially the inking appararo tus used on fast rotary printing-machines,

and the invention relates especially to a duotor mechanism for taking the ink from the ink fountain or supply.

The ordinary doctor-roller mechanism ,such as is used in connection with the ordinary rotary press, consists of a roller which reciprocates or oscillates between the fountainroller, which is motionless, or approximately so, and a fast-running distributor or receivzo ing roller. In other Words, the doctor-roller.

has to contact at one point of its oscillation with a stationary roller and at the other pointof its oscillation has to contact with a rapidlyrunning distributer-rollerp As'a result'the' doctor-roller, whichis made of glue and molasses and which is loosely journaled in its hearings or arms, in a short time is battered or twisted to pieces and requires replacing frequently, as when the ductor contacts withthe fast-running distributor it must start in motion therewith, and when the samecontacts with the substantially stationary fountain-roller this rotation must be stopped. To run any length of time with this ordinary con- 3 5 struction the doctor-roller must be made very hard and solid, and this in itself prevents good inking, for to do good inking a roller must have a soft surface. Again, in ordinary constructions it is not possible to oscillate the ductor-roller fasterthan once for every four turns of the plate-cylinders, and therefore at each trip the ductor-roller must carry ink enough for eight papersin other words, a lump. WVhen, as is soon going to be the case, 4 5 the speed of the commercial rotary web-press is doubled or greatly increased, the number of reciprocations to a revolution of the platecylinders must be reduced, necessitating a greater load of ink at each trip. In view of these difficulties the aim of my invention is to provide a doctor which is rotary in action and which is so rotated that the same will roll over the fountain-roller without slippage and ,so that the same will contact with the distributer or receiving roller and will turn 5 5 therewith, so that there will be substantially no strain put upon the periphery of the ductor-roller. In other words, the driving means for the ductor-roller is so arranged that the ductor will run in an orbit over the fountain- 6o roller and: turn with the receiving roller. Further, by making the doctor-roller rotate orbitally I can. do away with oscillations or reciprocations and provide a much faster running device, and also can use a plurality of ductor-rollers to take the ink from the fountain, and I can provide as many supplies of ink as desired for each revolution of the plate-cylinders. By my arrangement the ductor isrotary in every sense of the word. To understand'this-operation which I have thus'described, I will refer first to a small diagram toillustrate this action before describing the apparatus,-which I consider the the best mode of applying the principle of my invention,and this diagram is shown in Figure 5 of the drawings. In this figure, 1 represents afountain, and'J the fountain-roller thereof. 16 represents a ductor, and 14 a receivingdrum or distributor-cylinder. The ductor-roller 16 is mounted in rings 25, which are rotatedaround their center. The ductorroller carries a pinion 26, which meshes with a stationary gear 27. (Dotted lines.) Sup,- pose now that the velocity of rotation of the doctor is three hundred and fifty feet a minute, and suppose that the distributor or receiving cylinder 14 has a peripheral velocity of seven hundred feet per minute. Now as the doctor-roller turns around its center of c rotation it will also turn on its axis, and in doing so will roll over the face of the foun: tain-roller, and thus take ink without stopping or slippage. Having taken ink in its descent, its outer surface contacts with the 5 receiving-cylinder, and as the receiving-cylinder turns in the same direction and with the same velocity as the outside of the doctor a transfer of ink takes place between the doctor-roller and the receiving-cylinder in the loo most natural manner. Thus a rotary transfer of ink is obtained without either starting, stopping, or reciprocating the ductor-roller. It also will be seen that by this mechanism a small and nicely-distributed supply of ink can be carried from the fountain-roller to the receiving-cylinder and that the parts being essentially rotary in action may be driven at a high rate of speed. It also will be seen that as many ductor-rollers may be used in the device as desired. While this diagram illustrates the principle of my invention and such constructionis within the scope of my claims, I prefer to use a different form of apparatus in practical use, because in the device of the diagram the ductor or duetors rotate around the fountain and prevent access to the adjusting-screws of the fountain while the machine is in operation, and also by using a form of apparatus hereinafter described I avoid carrying the ductor roller or rollers into and out of contact with the receiving-roller.

Referring to the accompanying three sheets of drawings, which form part of this specification, Fig. 1 is a sectional diagram just inside of one of the side frames of a press, showing my improved apparatus. Fig. 2 is a sectional diagram of my improved inking apparatus, taken on the line 2 2 of Fig. 4. Fig. 3 is a view similar to Fig. 2, showing the parts in a different relative position. Fig. 4 is a cross-sectional elevation taken on the line 4 4 of Fig. 1, and Fig. 5 is the diagram before referred to.

Referring now to the first four figures, which illustrate whatI deem the best way now known to me to practically carry out my invention, A and B represent theordinary side frames of the machine. 0 represents the impression-cylinder, D the plate-cylinder, E the ink-drum, and F and F the form-rollers which form part of the first printing-couple of a rotary web-press of any construction.

G represents a composition roller which bears on the ink-drum E, and H represents an iron or steel drum on which the composition roller G hears.

- M represents a composition roller used for a purpose hereinafter described.

1 represents an ink fountain of any desired form, and J the roller thereof. This roller is given a slight turn or part of a revolution at intervals by any of the usual ratchet mechanisms, as K, the details of which it is not necessary to describe at length, so that the ink will be taken from the fountain up onto the surface of the roller J, or the roller J may be driven continuously at a slow speed. 10 represents a shaft which is mounted in bearings 11 in the side frames A and B and ,which has a gear or pinion 12 on the end thereof, by which the same is continuously rotated. Mounted on this shaft 10 are suitable arms orplates 13 and 130. J ournaled in these plates are two iron or steel receiving-rollers 14 and 140. 1 On the shafts of these receivingrollers are fastened arms 15 and 150, in which the grooves 19 and 190.

are mounted duetors 16 and 160. I have shown two duetors arranged in this way, although, of course, one or any number may be used as desired.

The arms 15 carry rollers 17, and the arms 150 carry similar rollers 170. These rollers fit in disks 18 and 180, which have circular grooves 19 and 190 out therein, and these disks are set eccentrically to the shaft 10 and are secured to the insides of the side frames, as shown.

The receiving-roller 14 has gears 20 20, arranged on the ends thereof, and the receivingroller 140 has gears 200 200 arranged on the endsthereof. Adriving-pinion22isarranged to mesh with one of the gears 20, and a driving-pinion 220 is arranged to mesh with one of the gears 200. These driving-gears 22 and 220 are meshed into an internal gear 23, which is secured to one of the side frames by means of supports 24, as shown.

The ductor 16 is rotated by hearing on the receiving-roller 14, and the ductor 160 is rotated by hearing on the receiving-roller 140.

In some casesthe duetors and receivingrollers may be geared together; but it is preferred in most instances to drive the duetorrollers by surface contact with the receivingrollers. .If the ductor-rollers are to be geared to the receiving-rollers, the ductor-rollersjwill be provided with gears on their ends to mesh with the gears on the receiving-rollers. Such gears 210 210 are shown on the ends of the ductor-roller 160 in Fig. 4.

I do not always propose to use two gears 20 20 on the ends of the receiving-roller 14, or two gears 200 200 on the ends of the receivingroller 140, as the rollers can be driven by being geared at one end only; but for presses of great width the gearing at both ends is desirable. When gearing at both ends of the receiving-rollers is used, the shafts on which the pinions 22 and 220 are mounted are eX- tended between the plates 13 and 130, and two driving-pinions 22 and 220 are provided to mesh With the gears 20. and 20 and 200 and 200 on the ends of the receiving-rollers.

I preferably use an internal gear on only one side of the machine, although of course it is within the scope of my invention to use an internal gear at each side.

The operation of the device is as follows: The parts are so positioned that the receiving-rollers as the'same rotate around the center of the shaft 10 will not touch the fountain-roller J, but will contact with the composition roller M. The ductor-rollers 16 and 160 being mounted in arms are controlled in position by the rollers 17 and 170 running in The disks 18 and 180 are so placed that the duetors 16 and 160 will be moved outwardly to engage and roll over the surface of the fountain-roller J, as shown in Fig. 2, and will be moved inwardly to clear the composition roller M, as shown in Fig. 3. By this construction the duetors will take the ink from the fountain-roller and give the same to the receiving-drums, and the receiving-drums will give the ink to the composition roller or cylinder 1N1. The gearing is so proportioned that when a receivingdrum contacts with the composition roller M the speed of the receiving-drum will be the same as the peripheral speed of the composition roller M, so that there will be no slippage or strain put on the composition roller M. By this construction a rapid and accurate transfer of ink takes place and a device is provided in which substantially all strain is taken from each ductor-roller, as each ductorroller is in constant contact with a receivingdrum and each receiving-drum contacts accurately with the composition roller M.

In some cases the rollers M and H may be omitted and the roller G used to take the ink from the receiving-drums; but I prefer generally to use three rollers M, H, and G, so as to get a further distribution of ink.

It will be seen that the inward and outward movement of the ductor-rollers will not disturb the rotation thereof, as such movement takes place about the axis of the receiving-drum, and also it will be seen that the gearing described provides a simple and neat form by which the ductors and receiving-drums are properly turned at the proper speed in the right direction.

The modification of my invention shown in the diagram Fig. 5 has been previously described.

Other forms of gearing and arrangements may be devised to work within the principle of my invention without departing from the scope of my invention as expressed in the claims.
