PRINTING PRESS Applicationlfiled January 23, 1930. Serial No. 422,905

.invention relates to printing presses and has torits object the provision of a new and improved form'and' arrangement of parts by the use of whichdistinctivemarkings may bemad-e on theoutside faces of critical papers or sections in the of the press whereby such marked papers shall define-the limits of successive equal-sized bundles or piles of papers or sections.

' It1is -.one of the-objects of my invention to provide a construction by p which adjustment may/be readily efiectedforvarying the number ofthe papers or.-sections in successive indicated bundles or for'varying the action of the printing and-controlling. mechanism for keepingthe-numberof the papers in the successive indicated bundles constant when a shift is made from straight run to .collection run: or .vice versa. o

It is.one,of\the objects ofmy invention to improve vmechani sins of this 'type 'in sundry detailshereinaitter specified. The preferred meansj'by .which'l'have accomplished my several-objects are illustratedin the accompanying .drawings .and ;.are hereinafter specifically described. That which I'believe to benew and desire to cover :by Letters Patent is set forthin the claims. fIn the-drawings,

Referring now to the several figures ofthe indicated by the same reference characters, 10 indicates a'bed plate, having frame members or standards 11 and 12 rising therefromv in spaced relation to each other, each of the standardsll and 12 being preferably formed 1n sections in the ordinary manner. Each of the unit sections ofthe press is provided with. form'cylinders 13, and impression cylinders 14, together withsuitable inking mechanisms for printing .a web 15 on both faces thereof, means being provided at the top of the section for cutting the web: 15 into two parts and for superposing one ofsuch web parts on the other, such two web portions be- 5 ing indicated by the numerals Miami 17. In Fig. 1, I have alsoindicatedtwo additional webs '18 and 19 which have been printed by the press section next-to the right of the .press sectionillustrated, and have shown also webs of thewebs being brought together over a roller 28 at the upper (edge of "the former structure indicated in Fig. 1 by the numeral 29. A secondformer 30 is also provideddt rectly opposite the former 29 for use if de sired for producing a folded product independently of that passing overtheformer29. Itwill be understood, of course, that'if desired the webs '16, 17, 18 and 19 might be handled over one of the formers and the webs 20,21, 22 and 23 handled over the other former. It will be understood also that in case all eight of the webs were run over a single one of the two formers,.in such case the web 16 wouldbe shifted to pass'under theroller '31 instead of over the roller 27 in. such case the web 20 I00 being passed over the roller 27 in lieu of the web 16.

In Figs. 3 to 7, in which my improved construction is shown in detail, the roller 27 there shown is the roller over which the web 16 or the web 20 is passed just before reaching the former as above described.

his roller 27 is provided with a gear 32 on the end of its shaft adjacent to the standard 11, by which gear 32 the roller 27 is to be driven at the same surface speed as that of the webs. In the construction shown, the circumference of the roller 27 is just half the size of the sheet longitudinally of the web as cut by the cutting and folding mechanism, with the result that the margins of successive pages passing over the roller come always at the same point circumferentially of the roller.

For supporting auxiliary printing means movably in position for operation upon the uppermost web passing to the former 29 or 30, I have provided a rock shaft 33 revolubly mounted in the standards 11 and 12, being provided with arms 34 extending therefrom,

' between the ends of which are mounted two ing over the roller 27 short shafts 35. Each of the shafts 35 is driven at the same angular speed as that of the roller 27 by means of intermeshing gears 36 and 37 mounted upon the shafts 35 and the roller 27, as is clearly shown in Fig. 4. Upon the inner end of each of the shafts 35, I have provided a head 38 equipped with a suitable printing plate 39 adapted when in operative position to print a distinctive marle ing of any approved form upon the web passthe roller 27 being provided with impression rings 40 for suitable coo ration with the printing plate. For inkmg the plate 39, I have provided a felt roller 41 supported by a bracket 42 above the head 38 in position to permit the plate 39 to engage the roller 41 upon each complete revolution of the shaft 35 and the parts carried thereby. The head 38 is of such size as to cause the face of the plate 39 to have the same surface speed as that of the roller 27 and the web 16. v

Means is provided for rocking the rock shaft 33 in timed relation to the rotation of the roller 27 for holding the printing plate 39 out of operative relation to the roller 27 during the greater portion of the time but permitting such auxiliary printing mechanism to descend into operative position as shown in Fig. 4 at timed intervals for printing a distinctive marking upon the outer face of the front page of certain predetermined papers or sections separated from each other by a predetermined number of intervening papers or sections. This means comprises a worm 43 carried by the shaft of the roller 27 with which worm meshes a worm gear 44 mounted on the upper end of a vertically disposed shaft 45. This shaft 45 is connected with a horizontally extending shaft 46 by means of beveled gears 47 and 48, the outer end of the shaft 46 being provided with a pinion 49. In the construction shown, the beveled gears 47 and 48 are of equal size, and the worm gearing has a ratio of 25 to 1, with the result that the pinion 49 is given a sin le rotation for each twenty-five rotations of the roller 27.

Adjacent to the pinion 49 on the outer face of the standard 12, I have revolubly mounted a gear 50 which is fixedly connected with a cam disc 51. The pinion 49 is operatively connected with the gear 50 by means of an idler gear 52 which is revolubly mounted upon a swingingly mounted arm or lever 53 so as to mesh with both the pinion 49 and said gear 50, the gear 52 being of just one-half the size of the gear 50, and four times as large as the pinion 49. With this construction, it will be appreciated that the cam disc 51 is given a complete rotation for every two hundred rotations of the roller 27, being a single complete rotation for every one hundred sheet lengths of web passing over the roller 27.

As is best shown in Fig. 7, the disc 51 is provided with a notch 54 at one point in its periphery, adapted to be engaged by a roller 55 carried by an arm 56 fixed upon the end of the rock shaft 33. The arrangement is such that'when. the roller 55 engages the outer pe riphery of the cam disc 51, each of the shafts 35 is held in slightly elevated position so that the printing plate 39 is revolved past the roller-27 without being brought into contact with the web passing over the roller. The arrangement is such, however,that when the roller 55 drops into the notch 54 of the cam disc, the rock shaft 33 is given a slight movement in counter-clockwise direction in Fig. 5 for bringing the arms 34 downwardly momentarily for permitting the printing plate 39 to have operative engagement with the web passing over the roller 27. The size of the notch 54 is such that the shaft 33 is held in its turned position only long enough for permitting a single operative engagement of the printing plate 39 with the web. The arrangement is such that the'gears 36 and 37 remain in mesh with each other when the shafts 35 are raised, with the result that the auxiliary printing mechanism is rotated both during the time when it is operative and when it is inoperative.

By the arrangement just described, in which the auxiliary printing mechanism is lowered into operative position once during each 200 revolutions of the roller 27 it is apparent that each one hundredth paper or section is given a distinctive marking when the press is operated upon a straight run basis. When, however, the press is operating upon a collect basis, the 100 lengths of web passing over the roller 27 during such 200 revolutions of said roller are, of course, folded into 50 horizontally extending shaft 46 in place of the pinion 49. For accomplishing this result, thearm-ror leverv 53 is moved downwardly and secured inposition. for proper meshing ofthe gear-52with the substituted gear or pinion 57. In'the construction shown, the gear or pinion-57 is'just twice as large as the pinion-49,,and just one-half the size of the gear 52. With the gear or pinion 57 in use upon the shaft 46, the cam disc 51 is. given,

a single revolution for each 100 revolutions of the roller'27. Upon this basis,the roller 55 carried by the arm or lever 56 ispermitted' to engage the notch 54 of the cam disc 51 just once for each fifty page lengths passing over the roller 27. That is to say, with the gear or pinion 57 in use, a distinctive marking is made upon each fiftieth paper or section when the press is operated upon the straight run basis; when the press is running upon a collect basis with the gear or pinion 57 in use, the distinctive markingis seen upon the front page of each twenty-fifth paper or section.

In Fig. 7 ,a gear 58 is substituted in lieu of the gear or pinion 57 upon the horizontally eX- tending shaft 46, such gear 58 being of the same size as the gear 52, thesubstitution of the larger gear 58 being permitted by reason ofthe downward adjustment'of the arm or lever 53. With the gear 58 in use, the cam disc 51 is given a single rotation for each 50 Y rotations of the roller 27. Upon this basis,

when the press is being operated upon a straight run basis, each twenty-fifth paper or section would show the distinctive marking upon its front face.

By the use of the mechanism as above described, I am enabled to divide the papers or sections coming from the folding mechanism of the press intoindicated bundles of either 25 sections or papers, sections or papers,

or 100 sections or papers. I am enabled to divide the papers or sections into either 25 or 50section bundles either when the press is runningupon astraight run basis or upon a collect basis. As will be very'readily understood, if it were desired to divide the product of the press into'bundles of any other predetermined number of units, this result could be obtained by the substitution of still other gears or pinions in lieu of the gears 57 and 58.

lVhile I prefer to employ the construction as illustrated in the drawings and as above described, it is to be understood that my invention isrnot to be limited to the precise form of mechanism as shown and described,

except so far as it may be so limited by the prior art, it being understood; that changes might well be made'in the, construction, withoutdeparting from the spirit of my invention.- c r I claimr:-. V v
