INKING MECHANISM.

Application led September 16, 1925. Serial No. 56,575.

This invention relates to improvements in inking mechanism for printing machines, and is designed particularly for use with the type of inking mechanism shownv in United States Patents 1,214,856, dated February 6, 1917, and 1,311,198, dated July 29. 1919. In the type of inking mechanism shown in these patents the ink is supplied through a series of separate conduits, one conduit being provided for each`column or other desired section of the forms` to be inked, and the ink is delivered under pressure to the conduits in regulated quantity by a plurality of pressure devices. as pumps, one pump being provided 'for each conduit.

In producing certain products, particularly products having printed illustrations, it is frequently necessary to print certain pages or parts of a page in ink of a diferent quality or color` from that by which the other pages of the product are printed, or it becomes necessary to supply .a heavier ink to such pages. t

It is the especial object of the present invention to produce an inking mechanism of the type above briey referred to, in which provision is made for supplyin different grades or colors of ink throug the 4distributing conduits, so that a page lor part of the page requiring it may receive a heavier or lighter ink than that from which the rest of the page is printed.

A further object of the invention is to produce sucha construction which is readily accessible for adjusting and repairing, and in which the change from one grade or color of ink to another may be readily and quickly effected by the pressman.

With these and other objects not specifically referred to, the invention consists in certain novel parts, arrangements and combinations which will be fully described in the accompanying drawings and the novel features pointed out in the claims hereunto annexed.

These drawings show one construction for effecting the objects of the invention, and in these drawings,-

Figure 1 is an end view, partly broken away, showing one printing couple and the improved inking mechanism and its preferred position with respect to the couple;

Figure 2 isl an enlarged detail View of the ink pump arrangement for supplying the two grades or colors of ink;

Figure 3 is an enlarged plan view of one end of the `inking mechanlsm showing the pumps and condults for one page of a form;

Figure 4 is a side view, partly in section, of the ink rail or delivery, the view being taken in the direction Lof the arrow 4 of Fig. 1, and

`Figure 5 is a detail sectional view of the ink pump rail or delivery, the view being taken on line 5 5 of Fig. 4 looking in the direction of arrow a of that figure.

Referring now to these drawings, one printing couple isdiagrammatically shown consisting of a form cylinder 1 and an impression cylinder 2 printing on a web W, these cylinders being mounted on shafts 3, 4 suitably lsupported in side framing 5. While the particular machine selected to illustrate the invention is a rotary machine in which both members of the printing couple are cylinders, it will be understood that the invention as to certain of its features will be useful in other types of printing machines and machines in which both the printing elev ments of the couple are not cylinders.

The form cylinder 1 is inked from a pair of distributing rolls 6, 7 which take ink from the distributing drum or cylinder 8 to which ink is supplied by a roll 9 from a fountain or ink roll 9.

In the construction shown, the form cylinder 1 is capacitated to carry four' lates widthwise of the cylinder, and each p ate is eight columns wide. These forms are inked from an inking mechanism in which the ink is supplied under pressure by suitable pumps through a plurality of conduits, these conduits being provided in the desired number so that each column or other desired section of the form is provided with its own dicated by the numeral 10, there being in the particular construction shown thirty-two of these conduits corresponding to the thirtytwo columns of a four page wide paper. Each of these conduits delivers to a nozzle 12 from which the ink passes to the fountain roll 9. These conduits are supported in a. long frame, which may be called an ink rail, this frame being indicated by the numeral 13. This rail is supported in suitable -inking mechanism. These conduits are inside frames 14.-. To enable the nozzles and the ends of the 'conduits to be easily accessible forthe pur ose of cleaning, etc., the delivery side of t e rail is formedwith a cap plate 15 hinged to the rail at 16, this rail being held in operative position by a spring Ink is delivered under pressure to these conduits by pumps, there being a pump for each conduit. These pumps may be of any desired mechanism, such as, for instance, the

pump shown inthe two White patents above referred to, but as a specific structure is unnecessary for an understanding of the prescolor. While this may be accomplished in various ways, in the particular construction shown there are provided two sets of pressure devices, as pumps, these pumps being carried in fountain casings 20, 21. These fountains are arranged side by side in a part of the press convenient of access, on a base 22 supported from an extension 23 of they frame 13, `before referred to, by which the ink rail is supported. One of these fountains, as the fountain 20, delivers to the conduits 10 and the other fountain, as fountain 21, delivers to a set of conduits marked 25.

These 'conduits 25 are short conduits and are joined with the conduits 10 through cou-4 plings or unions 26. These conduits 25 are provided in the samenumber as the conduits 10. y

Means are provided whereby the ink may be shut off from any conduit. This may be effected in various ways, as, for instance, by putting a valve in the conduit between the fountains and the unions 26, or by shutting ofi' any particular pump so that it would not supply any ink. A simple construction is that shown, in which valves 27 are provided in each of the conduits 25 and valves 28 are provided in each of the conduits 10.

Where the pressure devices are pumps, these pumps are or may be driven in any sultable way. In the particular construct1on illustrated, there is provided a shaft 29 suitably journalled in bearings in hanger-s 30 depending from the support or base 23, before referred to. At one end this shaft 1s provided with a mitre-gear 31 which meshes with the corresponding mitre 32 on the shaft 33 of the distributor cylinder 8, before referred to. The shaft of this cylinder carries a gear 34 which meshes with an intermediate 35 which in turn is driven from a gear 36 on the form cylinder shaft 3, before referred to.

The shaft 29, at each end, is provided with driving sprockets 37, 38 over which pass shown in Fig. 3 and that fountain 21 has a supply of heavy ink. Ink is now passing through the conduits 10 from fountain 20 to the nozzles, the valves 27 in conduits 25 being closed.

If now it be desired to supply heavy ink or ink of a different color to nozzles a, the valves 28 of conduits 10, 10 are closed and the valves 27 of conduits 25', 25 are open, it will thus be seen that heavy ink is now passing through the conduits and the unions 26 to nozzles a, b, in fountain 2l, but that light ink is passing to the remaining columns. With this construction, therefore, ink may be supplied both as to quality and quantity to any desired section of a column or any page. If it be desired to change from light ink to heavy ink for all the pages, this may be readily done by simply slipping the necessary sprocket chains and stopping the action of one of the pumps.

While the invention has been shown and described in its preferred form, it will be understood that certain changes and varia tions may be made in the arrangement and disposition of the parts and in the means for controlling the supply of ink to the conduits, and that the ink may be supplied under pressure in various ways and that such changes are within the scope of the invention as defined by the appended claims.

What I claim is:

1. In an inking mechanism for printing machines, feeding openings through which ink is fed underpressure for different columns or sections of the matter to be printed, a member to which ink is fed from the openings, and means whereby ink of one grade or color may be fed to any desired opening while ink of another grade or color is being fed to other openings.

2. In an linking mechanism for printing machines, feeding openings through which ink is fed under pressure for dierent columns or sections of the matter to be printed, a member to which ink is fed from the openings, separate conduits for each opening, an ink fountain for one grade or color of ink, an ink fountain for another grade or color of ink, and connections whereby ink from either fountain may be fed through the openings.

3. In an inking mechanism for printin machines, feeding openings through whic ink is fed under pressure for different col-A umns or sections of the matter to be printed, a member to which ink is fed from the openings, separate conduits for each opening, an ink supply of one grade or color of ink, an ink supply of another grade or color of ink,

ronolults from both ink supplies to the rst nuned conduits, and valves VFor controlling rho supply conduits, whereby ink may be iofl through any opening from either ink supply.

E1n an nking mechanism for pril'ltng nmchrnes, feedlng opemngs through Whlch mk 1s fed under pressure for dlerent co1- runns or sections of the matter to be printed,
