14 Claims.

My invention relates in general to printing devices. It relates more in particular to a printing attachment adapted to supplement a conventional type of printing press to secure a color effect.

Recently there has beenv a great demand'on the part of advertisers for color in newspapers. Some newspapers have installed full color equipment and others have modified existing presses to make it possible to print'in color. I have found, however, that printing an entire advertisement in color is not necessary to make the advertisement stand out, but any type of color may be used which will have the effect of attracting attention of the reader. The color may be employed either in the margin, down the center of the page, or in any other place on the page, depending upon the set up, which will have the desired attracting prope yg The principal object of my present invention is the provision of mechanism which can be used for this purpose. I

Anotherobject is the provision of a printing attachment which can be used as an adjunct with substantially any type of printing equipment in which the paper is moved linearly.

Another object is the provision of improved inking means in auxiliary printing apparatus.

Another object is the provision of an improved type of printing roller particularly adapted for use in auxiliary press equipment.

Another object is the provision of an auxiliary printing device which will be of substantially universal adjustment.

Other objects and features of the invention will be apparent from a consideration of the following detailed description taken with the accompanying drawings, wherein 'Fig. 1 is an elevational View showing one embodiment of the device of my invention;

Fig. 2 is a plan view thereof; Fig. 3 is a sectional View taken on the line 33 of Fig. 2;

. Fig. 4 is a transverse sectional view taken on the line 4-4 of Fig. 1;

Fig. 5 is a fragmentary, sectional view partly shown in plan toillustrate features of construction;

Fig. 6 is a fragmentary plan view;

Fig. '7 is a slightly enlarged sectional view taken on the line l-'! of Fig. 2; and

Fig. 8 shows a fragmentary section of a newspaper illustrating one manner of using the de- 7 Vice of my invention.

According to the general features of my invention, Iv provide a roller having a composition to engage amoving article such as a moving strip of paper with suitable friction. Composition'rubber with the printing indicia in relief is very satisfac- 60' tory fortheiipurpose. Ink supplying mechanism is provided, and the ink supplying mechanism is operated by power derived from the movement. of the printing roller by the paper. The roller and ink supplying mechanism are preferably provided as a single unit and the unit itself is designed to be mounted in any position on any type of press or equipment over which the paper is moved. Lateral adjustment is provided to control the position on the paper at which the roller will print, and a further adjustment is provided to control the impression against the paper. By means of this latter adjustment, the roller may be taken out of contact with the paper or the firmness of the impression adjusted as desired.

The main purpose of the mechanism is to print indicia running longitudinally of the paper. The position is conveniently along one or both margins, along the center of the page, or in any other suitable position depending upon the character of the advertisement. In Fig. 8, the term $-Day would be printed by the mechanism of my inventionwhile the remaining portion of the page would, for example, be the ordinary newspaper print. As an example, the newspaper print would be in the conventional black while the print $-Day might conveniently be in red. Any

type of indicia can, of course, be used. In an automobile advertisement, for example, the in dicia printed by my mechanism might be a series of small automobiles. Naturally, it is impossible to give even a representative number of illustrations, as the particular advertisement or advertisements being featured would determine the oharacterof indicia to be used to attract the reader. While usually the mechanism of my invention would be adjusted to print a strip running vertically on the page, by proper positioning of the printing roller it may under some conditions be made to print laterally of the page. In bringing this about, the mechanism of my invention may, for example, be mounted onv a folder, that is, the type of machine used in some plants for folding.

Referring now to the drawings, the embodiment of the invention there shown comprises a main frame iii which is adjustable along a rod H. The frame with the hinge portion 52 is adapted to engage around the rod H and at any selected position to be clamped thereon by means of a cap screw E3. The rod ii is made out of round to prevent the frame from tipping. In the present form, I show a key it engaging in a keyway of the frame portion ll.

Above the main frame I support a vessel !6 which also comprises part of the frame. This vessel is disposed in a channel formed in the top of the main frame, and a pair of strips ll (Fig. 4) screwed to the main frame engage over the top of shoulders provided on the vessel It. Thisvessel is adapted to carry ink l8 which is 'mediate its ends at 42.

. U-shaped frame at 59. low the arm 51 are employed to regulate the position of the Ushaped member with respect fed thereto from an inverted bottle is. The ink the cup barometer and in a manner well under stood the level of ink in the vessel I8 is maintained by this arrangement.

threaded into a boss formed'in thevessel to provide for adjustment by means of which the height of the ink in the open portion of the vessel can be controlled. v t

A roller supporting frame 22 is secured to one end of the vessel 16 by cap screws 23; Thisframe has one arm 2 which carries an integral house ing 26 (Fig. 5) Within which housing a shaft 21' is rotatably journaled. Preferably I'eniploy' a ball bearing support for the shaft 21', the ball.

29 on its outer periphery. The hub of the wheel 28 extends axially and is adapted to receive a nut 35 by means of which a plate 32 is clamped against. the printing band. The wheel 28 has.

an annular flange 28a whichco operates with the plate 32to hold the printing band in fixed position. The entire assembly including the wheel 28, the printing band 29, and plate comprises the printing roller. 7

Ink is delivered to the printing roller from a transfer rollerv 33. This transfer roller in turn receives ink from an oscillating ink drum 34 and.

the latter is supplied by a ductor roller 36 which picks the ink up from the; vessel l5. These rollers are operated by the printing roller through mechanism which will now be described.

The shaft 21 has secured thereto a worm 3'8 meshing with a worm gear 38 carried on a vertical shaft 39.journaled in a portion of the frame.

An eccentric boss 39 carried by the worm gear 38 engages in a slot in. an arm 4i pivoted inter- This arm M has a, pin 13 at its free end engaging in an annularslot a roller M; This roller is pinned to shaft which carriesv the ink drum 34. It is, moreover, .journaled and slidably supported in the frame so that the resulting oscillating motion imparted to it through the eccentric 39 and the arm l will be effective to distribute the ink uniformly and evenly over the transferroller 33.

The ductor roll 35 is carried ona shaft i'l loosely carried on the ends of a generally U- shapedmember 48 pivoted to the frame by cap screws 39. This member is normally held upwardly by a tension spring 5i. Itis adapted, however, to be moved downwardly aboutits pivot so as to project the ductor roller into an open portion of the vessel It to pickup the ink. For

imparting the necessary movement to the U- shaped member 58 to obtain this function, I provide a face cam 52 on the worm gear 38. This engagesunder a roller 53 to raise it, and the roller is journaled on an arm 5 pinnedto 'a shaft 56 journaled in a portion of the frame. The opposite end of the shaft 58 carries an arm 5?. The arms 56 and 5? taken together func tion somewhat as a bell crank in that when arm 5% is raised through the cam and roller, the arm 5i is lowered. The outer end of arm 5'? is aper tured to receive a toggle link 58 pivotedto the Nuts "6| above and be to the arm 5'! and so control the movement of the U-shaped arm.

The neck. of the bottle l9 extends into a support. 2| which is 1 have the roller 64 to. bear against.

ing roller through friction. In the position which 1 is supported in the bottle 19 on the principle of V the ductor has in full lines, which is its normal ductor roller projects into the ink. This is further prevented by a screen 62 which sets over the top of the open space in theve'ssel It. This screen has the function of arresting any rotary movement which the ductor roller may still have and also-of limiting the insertion of the duct-or roller into the ink. This makes itv unnecessary to adjust the movement of the ductor roller and.

height of the ink within extremely close limits.

'Sincethe ductor roller shaft is'only. loosely car-- ried in the vertical slots in the U-shaped member, the movement of the ductor roller can be arrested by the screen independent of how far the U-shaped memberitself will move.

As previously described, thefprintin'g. roller is.

adapted to engage a moving article in order to print. onto such movingarticle the indicia carried in relief on the. periphery of the printing.

roller. In the drawings, I show a strip of pa-.

per running between a pair of idler rollersa and S6. The position of the-printing roller is such that it can engage the, paper and still understood that this is a more or. less schematic.

It willbe V showingifor the purpose of illustration.

printing roller may engage the paper. at any position and any type of bearing surface may be provided at the point of contact. For exam-- ple, a fiat, stationary surface over which the paper moves can be used with satisfaction; In order to adjust the impressionv of the print-j ing roller, I provide an arbor 61 secured'to the main frame IE! and having a forked portionadapted toengage inan annular groove or channel in an adjusting nut 68/ This adjusting nut is threaded on a bolt 69- secured .to the vessel portion l6. By turning. the adjusting nut 68, the vessel portion with'the attached framemembers and apparatus mounted thereon can be moved toward or away from the paper. A'lock nut i l is: i

also provided to maintain'theimpression constant.

.I have previously noted that" the device of my invention may be mounted-to operate onthe moving paper at substantially any point and on any type of printing device in which the paper is moved continuously. Accordingly, I show por -N tions of the press frame 12 and I3 broken away to conserve space. The rod H which is also. broken away to conserve space is shown attached by suitable means to the frame members. It will be understood that this is merely anillustrative mounting" arrangement and, that particular conditionswill require. some slight modifications in supporting structure readily made'by a skilled mechanic; i What I claim as Letters Patent of the United States is: 7
