Patented May 11, 1948 NEWSPAPER STRIPIN G DEVICE Auburn Taylor, Charleston, W. Va., assignor to The Goss Printing Press Company, Chicago, Ill.,. a corporation of Illinois Application April 11, 1944, Serial No. 530,463

Claims. f 1 I This invention relates to new and useful improvements in apparatus for applying a stripe or. streak to a web' of paper as it passes through a printing press, particularly for app y g a stripe or streak of distinctive color for indicating a, particular edition of a newspaper. A commonly used color is blue, and these editions are sometimes called ,blue streak editions.

Objects and advantages of the invention will be set forth in part hereinafter and in part will be obvious herefrom, or may be learned by practice with the invention, the same being realized and attained by means of the instrumentalities and combinations pointed out in the appended claims.

The invention consists in the novel parts, constructions, arrangements, combinations and improvements herein shown and described.

The accompanying drawings, referred to here- 'in and constituting a part hereof, illustrate one embodiment of the invention, and together with the description, serve to explain the principles of the invention.

or the drawings:

Fig. 1 is a side view showing a portion of a printing press on which is mounted a typical and illustrative embodiment of the present in vention;

Fig. 2 is an end view of Fig. 1 looking from the right;

Fig. 3 is an enlarged vertical section taken on the line 3-3 of Fig. 2; and

a Fig. 4 is a fragmentary sectional view of the detail taken on the line 4-4 of Fig.3.

The striping device of the present invention is mounted on some suitable part 01' a printing press, preferably the former, so as to apply one or more stripes of colored ink to the printed newspaper in oneor more outer margins thereof, or along a folded edge thereof. The most important object of the present invention is to provide a striping apparatus which is simple in structure and operation, which involves no moving or rotating parts, and which isvariably po sitionable for accurately locating it with respect to the web.

The invention comprises one or more flat faced nozzles, supplied with ink, preferably by gravity, from an inkpot, which nozzles are positioned to press firmly against the moving web for applying a streak or stripe of ink to the web, of a width as determined by the width, of the nozzle. An ink that is absorbed readily by the paper should be used, such,- for example, as a water base ink or a thin oil ink. The nozzle should press fairly snugly against the web so that there is no lateral spreading or leakage of the ink, and this may be accomplished by providing a shallow recess in the former directly opposite the mouth of the nozzle so that the nozzle presses V 2 the web a small amount into the shallow recess. the web being thereby tensioned over the mouth of the'nozzle, and acting as a closure therefor.

'I'hestriping nozzles are mounted so as to be variably positionable laterally with respect to the printed web so that the colored stripe is accurately located in the desired margin. 1111s is preferably accomplished by having the nozzles mounted on a guide, manually operated, threaded means being utilized for moving and setting the nozzles to the proper positions on their guides.

Ink is supplied to the several nozzles from inkpots, preferably individual inkpots so that different colored inks may be supplied, if desired, to different nozzles. In the preferred embodiment the nozzles and their respective inkpots are each movable as a unit for positioning them as above described.

The several nozzles and their respective inkpots are conveniently mounted on a bracket secured to the former of the press and this bracket,

in addition to being readily attachable and detachable from the press, is variably positionable with respect to the former for giving adjustment of the nozzles with respect to the former.

It will be understood that the foregoing genera] description and the following detailed description as well, are exemplary and explanatory of the invention but are not restrictive thereof.

Referring now in detail to the drawings:

A bracket 2 is secured to a portion 4 of the framework of the press, and this bracket in turn supports a casting indicated generally at 6, in more or less parallel relationship with the usual former 8 of the press, over which former the webit! passes after passing over guide rolls l2. The former 8 is provided with shallow recesses ll located just below the margins of the printed web.

The stripe applying device of the present invention comprises a hollow, fiat-faced, ink-applying nozzle [6, which as shown in Fig. 3 is adapted to press against the web in and to press the web slightly into the recess I 4 for tensionthreaded lower end of rod 28 carrying the valve 22. Ink from the inkpot 26 simply flows to the nozzles by gravity and the valve 22 is not intended as a needle valve control. Valve 22 is operated by turning wing nut 29. If the speed of the web increasea'more ink is drawn down into the nozzles.

In order to provide for the lateral positioning of the nozzles, casting 6 is provided with

guide rods

30 and 32. Movable on these guide rods in suitable apertures is a support 34 for the inkpot and its nozzle, a lock collar 33 being keyed to the extension 24 of the inkpot. a d this lock collar supports the inkpot and in turn rests on their respective nozzles laterally with respect to the web.

Means are also provided for raising and low ering the nozzle lli'with reference to the paper III. For this purpose the'guide rod 32 is mounted eccentrically for rotation in its bushings and may be turned by the knob 33 attached to one end of the rod. Rod 32 fits .in recess 32' so that rotation of the rod raises or lowers the nozzle l8 by pivoting around the guide rod 30. Rod 32 is preferably frictionally held so that accidental rotation does not occur.

The casting 3 carrying the nozzles and inkpots is slidably and variably positionable on the shelf 2' of the bracket 2 in any suitable way, such, for

example, as by a bolt 46 engaging with 2' and engaging in a slot in the lower portion 42 of the casting 6. In order to move 6 and 42 back and forth on the shelf 2', there is provided a threaded adjusting screw 44 secured to a bearing 46 carried by bracket 2, the threaded rod engaging with extension 42. Turning of the threaded rod 44 by the knob 48 will move the casting 3 toward and away from the face of the former, thereby giving a close and accurate adjustment of the nozzles with respect to their distance from the former.

The adjustment, provided by the guide rod 32 and the adjustment provided by the variable positioning of the frame or casting 6 on bracket 22', each enables the nozzles to be positioned at different distances from the former for accommodating webs of varying thickness. In newspaper work, where this invention is used, there may be anywhere from one to eight thicknesses of paper passing over the former 8 and the described adjustments enable the nozzles to be set for any thickness. The adjustment provided by movement of 6 on the bracket 2 positions both ink nozzles, while the adjustments provided by rods 32 position the nozzles individually.

While the invention has been described as posi-- tioned over the former, it could be positioned over some other appropriate part of the press.

By suitable positioning of the two nozzles shown in Fig. 2, they maybe arranged to make parallel stripes, as shown in Fig. 4. Such parallel stripes may be side by side, as shown in Fig. 4, or they could be spaced apart; the two stripes, for example, could be spaced apart by the width of one stripe and if red and blue inks were used for the stripes the effect would be that or a red, white and blue striping. v

The invention in its broader aspects is not limited to the specific mechanisms shown and described but departures may be made therefrom within the scope of the accompanying claims without departing from the principles of the invention and without sacrificing its chief advan-' tages.

I claim as my invention: i.
