Application filed September 16, 1925. Serial No. 56,574.

This invention relates to certain improvements in inking mechanism for printing machines.

In certain types of inking mechanism the ink is delivered to the distributing member from a plurality of independent conduits, the ink being forced through these conduits under pressure, a separate conduit being pro- .vided for each column or other desired sectionof the form. In this type of inking mechanism the conduits deliver to the nozzles which are arranged to extend across and closely adjacent the ink rolls, these nozzles being carried in a frame which is generally known as the ink rail. To effect a good disposition of the ink, this ink rail must be closely adjacent the roll to which it delivers, and to obtain the correct adjustments should have substantially the same curvature asthe roll. It is difiicult to make the distributing surface of these ink rails even widthwise of the rail, irregularities occurring which frequently cause too much ink to be taken up at one part of the rail, with the result that the cylinder-or ink roll will receive more ink than it delivers and ink is wasted by being-thrown oif the cylinder, and this in addition makes a dirty pressroom.

It is the especial object of the present invention to provide an ink rail which will act to smooth out .any surplus ink that may gather on the cylinder, so that such inkis not thrown off the cylinder, and which Wlll assist in distributing the ink and which can.

be made adjustable so that it will present a smooth even surface across the cylinder.

It is a further object of the invention to produce an ink rail of this character which can be adjusted to some extent according to the thickness or grade of ink'that is being used and at any particular point across the cylinder to which the inkis delivered.

' With these and other objects not specifically referred to in view, the invention consists 1n certam novel parts, arrangements and combinations whichwill be fully described in connection with the accompanyin drawings, which show one embodiment o the-invention, and the novel features then pointed out in the claims hereunto annexed;

In these drawings,

Figural is a'more'or less diagrammatic side elevation of a pair of printing cylinders showing the relation of the inking mechanism .and the improved ink rail;

F1gure 2 is aside view of the improved 111k rail looking in the direction of arrow 2 of Fig. 1;

Figure 3 is a detail sectional view on an enlarged scale. the section beingtaken on the line 33 of Fig. 2, and

Figure is a section taken on the line 4-4 of Fig. 3 looking/in the direction of the arrow.

Referring now to these drawings, the invention has been shown as applied to a rotary machine in which both members of the pr nting couples are cylinders. I It will be understood, however, that the. invention is capable of use with printing machinesin which both members of the couple are not cylinders, and the invention is not to be restricted to the machine shown. i

For the purpose of illustration, there has been shown one couple of a rotary press, whlch includes a form cylinder 1 and an impression cylinder2, these cylinders being mounted on shafts 3,4 suitably journalled in side frames 5 of the machine. The form cylinder is inked from an ink or fountain roll 6 through a roll 7 which transfers ink to a distributing cylinder 8 mounted on the shaft 9, this cylinder 9 in turn supplying ink to two distributing rolls 10,11 which ink each column or other desired section of the form or forms on the cylinders. In the particular construction shown, there are thirty,- two of these conduits for supplying ink to four page wide plates, each pa being eight columns wide. Ink is delivere to these conduits under pressure by means of a plural: ity of pumps, not shown, which are. located in the ink fountain 13. I These conduits deliver the ink'to the fountain rolls 6' through nozzles 14 in an ink frame or rail 15 which is suitably supported in side frames 16. The conduits are also carried on or in this rail, being shown as located in a recess 17 in the rail. The arts are so formed that thedischargs ends 0 the nozzles lie closely adjacent t e periphery of the fountain cylinder 6, and to afiordready access to the nozzles and the discharge aroun vsurface curved to correspond substantially to the periphery of the ink cylinder 6 this portion of the rail extending around the periphery of the cylinder for a suflicient distance to insure a good distribution of the ink and acting to prevent the ink from gathering in globules and being thrown off the c linder in case of excessive supply of ink t irough the nozzles. While the specific construction of this ink rail may be varied' to some extent, in the particular construction illustrated there is provided a curved plate of light met al which can be 'ven a smooth polish and which can be ma e to have substantially the curvature of the periphery of the cylinder, this plate being marked 21. This plate forms a continuation of the ink rail itself, so that the solid art of the ink rail and that part which is di cult to form truly without uneven sections can be made very short. This plate at one end is secured to the ink rail in any suitable way, as b screws 22. This plate extends below the ink rail and ficient distance to effect its unctions, and

i the rail is mounted so that it can be adjusted widthwise of the machine at various points.

Thus, if heavy ink is being sup lied at one place across the form and lig ter ink at another place, or the quantity of ink varies, the plate may be adjusted for this so that an even distribution of ink is effected through out the width of the rail. While this adjustment may be of various characters, in the particular construction illustrated "the rail is seated against springs which may be ad-' justed tobring the plate nearer to or farther from the peripher of the cylinder. As shown, the ink M has secured thereto a bracket 23 which supports one end of a ring rod construction 24, the other end of t is rod bein secured to a bracket 25 fast on the back of t e late, and preferably toward. its lower end. y adjusting a nut 26 of the spri rod construction, the plate may be mov toward or from the cylinder 6, a suficient number of these rings, as indicated in Fig. 4, being provi ed. to effect the desired ad'ustment of the plate widthwise of the machine. 7

With the construction described, the ink on the cylinder 6 is smoothed out and evenly distributed onthe surface of the cylinder, the ink rail forming a mixing surface or area of substantial extent. The formation of lobules whichwill tend to fly 'ofi the cylin-' der is prevented and the rail can be adjusted the periphery of the c linder a suf- -machines feeding openingsthroug widthwise of the machine to accommodate any quality or grade of ink slwlplplied at different points on the cylinder. ile the invention has been shown in a practical-and efi'ecttive form, it will be understood that it isnot to be restricted to the exact construction of the plate or the means for seating the plate as shown, but that changes and variations may be made in this without departing from the invention as defined in the claims annexed hereto.
