MULTIPLE-PRINTING PRESS.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed June 21, 1906. Serial No. 322,667.

To all whom it 'may concern:

Be it known that I, AUGUST SCHEUERER, Jr., a citizen of the United States, and residing at Hoboken, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in l\lultiple-Printin(r Presses, of which the following is a specication, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to multiple-color printing machines, and the object thereof is to provide a machine of this class with means whereby a series of different colors cart be applied successively to the material which is to be printed upon in order to obtain the finished design or representation by a series of overlying tints of different colors; another object being to apply different tints of the same color simultaneously to a number of sheets to be rinted upon at each revolution of the orm cylinder; another object being to provide means whereby the adjustment of the separate and most essential members of the printing press is facilitated and whereby also the inking mechanism as a whole can be entirely separated from the rest of the printing machine.

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvements are designated by suitable reference characters in each of the views, and in which Figure 1 represents a side View of my improved machine; Fig. 2 a longitudinal vertical section of the same; Fig. 3 an end view of the same; Fig. 4 a detail sectional View of a part of the inking mechanism; and, Fig. 5 a section on the line 5-5 of Fig. 4. Fig. 6 is a partial view showing details of construction.

In the drawings 1 is the main frame which supports the form-cylinder 2, the transfer cylinder 3, the paper cylinder 4, the paper roll 5, paper tension 6 and various other adjuncts more specifically referred to below. The shaft 7 of the form-cylinder 2 rests in solid bearings which form part of the main frame 1. The shaft 8 of the transfer cylinder 3 rests in vertically adjustable bearings 9 which can be operated and regulated by means of the hand operated worm gear 10 and which will facilitate the necessary alinement of the cylinder 3 superimposed upon the cylinders 2 and 4. The shaft -11 of the paper cylinder 4 rests in horizontally adjustable bearings 12 which consist of the usual brasses and followers with adjusting screws 13 well known in the art. The inking mechanism 14 consists of various fountains and rollers necessary for this class of printing machines and is attachedto a separate frame 15. This frame has truck rollers 16 which travel over rails 17 which latter are stationary on the bed plate 18 which also forms the bed plate for the main frame 1. Two lines of rack-gearing 19 are also attached to the bed plate 18 and into which gear the wheels 100 which latter are connected by the transverse shaft 20. One of the gear wheels 100 is driven by means of the pinion 101 which latter can be operated by means of a handscrank 21 and by means of this series of gearing, the frame 15 and the therewith connected inking mechanism 14 is caused to travel longitudinally over the rails 17 whereby the frame 15 can, at the will of the operator, be brought nearer to or farther from the main frame 1. The object of this construction is to permit an easy access to the inking mechansm and to the formcylinder. The frame 15 can be locked to the frame 1 as seen in Fig. 2 of the drawings by means of draw-bolts 22 which ass through a pair of lugs 23, one of which is part of either of the frames, or by means of any other suitable locking mechanlsm.

The forni-cylinder 2, as shown in the various views of the drawings, is intended for the transference of eight diHerent tints or colors and is served by means of an inking mechanism consisting of eight different sets of inking rollers, fountains etc. and for the sake of illustration the following series of colors are intended to be used in connection therewith, namely, inking rollers 24 Supply a light yellow color, inking rollers 25 a dark yellow, rollers 2G light red, rollers 27-dark red, rollers 28 light blue, rollers 29 dark blue, rollers 30 gray, and rollers 31 a brown color. These sets of rollers are placed radially to the axis of the form-cylinder, and as illustrated in detail in Figs. 2, 4 and 5 of the drawings, each consists of the usual fountain 32, ducker 33, distributing inking cylinder 34, riders 35 and form-rollers 36. The shafts 37 of the distributing inking cylinders 34 are placed in radial slots 38 in the frame 15 and extend outwardly of the same. The shafts 3S) of the riders and the shafts 40 of the form-rollers are placed in runways 41 arranged radially to thc axis of the forni cylinder 2, and both ends of all the shafts 40 are provided with groovcd contact rollers 141 which in turn travel over the periphery of multiple grooved guide rollers 42 which latter are fastened to the ends of the forni cylinder 2 and rotate with the same for the purpose hereinafter more fully described.

In order to keep all inlring rollers concenA tric to the outer peripherv of the form-cylinder, the projecting ends of the shaft 37 of the various distributil'ig inking cylinders, which project outwardly of the frame 15 as described above, are encircled by a semicircular band 43 as seen in Fig. 1 of the drawings. This band 43, midway is supported at 44, and likewise with its ends 45 on the frame 15 and can be placed in proper operative position by means of set-screws 46 which will permit a tightening and loosening of all inking rollers by drawing the semi-circular band 43 toward or away from the vertical joint between the frames 1 and 15. The upper four inlring sets 24, 25, 2G and 27 will gravitate toward the center of the form-cylinder, while the lower four inking sets 28, 29, 3() and 31 are adjustable toward the form-cylinder 2 by means of special set-screws 47 which pass through the band 43 and bear upon the projecting shafts of these sets. The set-screws 47 may be dis pensed with and a compressing spring 48 centrally located at the supporting point 44 may be employed to force the band. 43 and the inking rollers inwardly toward the forni roller.

The circumference of the form-cylinder 2 is divided into as many sections, eight in this case, as there are inking sets, each section being designed to carry one segment forni and each form is designed to receive its respective color from one of the inking sets and afterward to transfer the color to a respective section of the transfer cylinder 3. This cylinder 2 is preferably composed of end spiders 49 having a hub 50 and outer circumferential bearing ring 51, or one or more additional spiders centrally located between the end spiders may be employed in cases of exceptional width of the printing press. Mounted on the outer periphery of the bearing ring 51 are the eight segment forms 52, 53, 54, 55, 56, 57, 58 and 59 with a longitudinal open space 66 left between each two adjoinin segment forms, it being understood that t e peri heral lengths of each segment form as we l as its transverse width from end to end are the respective dimensions of the sheet which is 'to receive the different impressions thereon. As seen in Figs. 4 and 5 each segment form has inwardly extending transverse lugs 60 which fit in accurately spaced recesses (51 cut into the outer cireuniference of the bearing ring 51. Set-screws ('12 placed in the bearing ring 51 will permit radial adjustment of either end while locking set-screws ($3 are elnployed to facilitate transverse adjustment and also to securely fasten th(` segment forms into position.

ln order to attach the form plate (511 which contains the subject matter that is to be transferred and to be printed in the various colors on the segment forms 52 to 5S) inclusive, adjusting follower plates (i5 are introduced into thc open spaces (3G between the adjoining forms. These plates are provided with a row of buttons G7 to which the forni plate G4 can be attached, and a number of set-screws G3 which bear against the rigid sides that form thc recess (it) will force the follower plate G5 and the therewith connected form plate G5 outwardly and thereby tighten and rigidly secure the same. Projecting lugs G9 of the bearing ring 51 and fitted in the corresponding recesses 7() of the follower plate (35 hold the latter in its posi tion and prevent radial dislodgment of the saine.

As seen in Figs. 3 and 5 of the drawings, each end of the form-cylinder 2 has rigidly fastened thereto by bolts or rivets 71, and concentrically placed to the axis of the shaft 7, a guide roller 42 as above referred to. Each of the guide rollers 42 is provided with a plurality of circumferential ridges 72 and intervening grooves 73, the number of said ridges on each guide roller corresponds with the number of the sets of contact rollers 141 which latter are mounted on the shafts 40 of the forni-rollers 36. Three of said contact rollers 141 form a` set and each set occupies one of the circumferential ridges 72 of the guide roller 42 on either side of the for1ncylinder 2, and upon rotation of the latter the contact rollers 141 will rotate upon their own axis, being held in frictional Contact with the guide rollers as above described by means of the encircling band 43 and thc therewith connected set screws 47. Each one of the circumferential ridges 72 of the guide rollers 42, as illustrated in Figs. 2, 3 and 4, has at 74 a slight segmental depression which is concentrlc to the outer periphery of the same and the length of the are of each of said depressions 74 is equal to the length of the arc of each of the forms 52 to 59 inclusive plus the length of the arc of one of the recesses 66. The radial distances of the ridges 72 and that of the depression 74 are so arranged that the ridges 72 will cause the contact rollers 141 and the therewith connected form-rollers 36 to travel slightly above the outer surface of the form plate 64 attached to the form-cylinder 2, but when the contact rollers 41 travel over the depressed path which coincides with the surface of the respective form plates, the latter will, during the travel over this dcpressed path, become subjected to the inking action of the form rollers 24 to 31 inclusive. It will thus be seen that during one revolution of the form-cylinder 72 all the inking attachments with their form rollers will successively be set in operation and that the form plates attached t: the segment form 52 can receive the color only from the inking attaclnnent 24, that of 53 from 25, and etc. As shown in Fig. 2 olf the drawings the inking attachment 24 is in the act of traveling over the form plate attached to the form 52, while all the other inking attachments which are out of action will be held in suspension above their form plates by reason of the contact rollers 141 riding on the higher ridges 73 ot' the guide rollers 42.

The transfer cylinder 3 is of the usual construction and is subdivided into eight parts respectively numbered 75, 70, 77 to 82, corresponding to the eight subdivisions of the form-cylinder 2, and is of equal diameter thereto, each of the subdivisions is properly rubber blanketed and is adapted to receive the transferring impressions from the form plates of the form-cylinder 2 when revolving in opposite directions to the latter.

A paper Vcylinder 4 has been introduced which is of novel construction and which is designed to receive upon the sheets of paper carried forwardly by the same, the various color impressions brought thereto by the transfer cylinder 3. The circumference of the paper cylinder 4 is proportionate to the form-cylinder and to the transfer cylinder as is n-l-l to a, namely, its circumference possesses one segmental surface more than that of the form-cylinder, and in this ease has nine segments numbered on the drawings 83 to 91, and each two adjoining segments have one intervening open space 92 equal to that of the open space 66 of the form-cylinder 2 and that of the open space 93 of the transfer' cylinder 3, and it becomes apparent that in revolving the three cylinders in the direction of the arrows as seen in Fig. 2 of the drawings the segment surfaces will be brought into and out of contact at the same time, and that between cylinders 2 and 3 always the same surfaces will meet, but that between cylinders 3 and 4 successively alternating segment surfaces of the paper cylinder 4 will come in contact with the segment surfaces of the transfer cylinder 3. The recesses 92 are provided with gripping attachments 94 of 'any a proved construction. The paper roll 5, t e paper tension 6, the rotary cutter 95, the releasing grip 96 and the take-olf 97 are of any of the old approved forms and are not specifically claimed herein.

The fountain 98 with metal roller 99 and distributing roller 102, the latter covered with mole skin, introduced as seen in Fig. 2. ol' the drawings, and the object` thereof is to subject the printed sheets, when they have arrived at this point of their travel around the axis oli' the paper cylinder 4, to the action of a` neutralizing solution which latter has the tendency to rapidly dry the last color imparted to the sheet and to place the same in condition Isuitable to receive the next succeeding color impression. The action and operation of this cylinder is as lollo\rs;'l `he gripping attaehnient 94 takes hold ot' the sheit of paper 103, just cut in the proper length by the rotary cutter 95, and the sheet will attach itself in the forward movement of the cylinder 4 to the segment 91 and will receive its tirst color impressionH-light yellow-as soon as it comes in contact with the segment T9 oi the transfer cylinder rl`he prior sheet resting on the segment 83 is commencing to receive the last color impression-brown-fro1n transfer segment 80 and will become detached therefrom when it arrives at the take-ott' 90, the last finished printed sheet having become detached prior to this from the segment 90 which as shown in Fig. 2 of the drawing is waiting the reception of a new sheet, with the gripping attachment 104 open, as soon as the latter arrives in the position now occupied by the grip 94. The sheet on segment 84 on its seventh revolution around the cylinder 4 has just received the seventh color impression-graythe sheet on segment 85, on its sixth revolution around the cylinder 4 has lately linished receiving the sixth color impression-dark blue-and so on. Each one of the sheets of paper makes eight revolutions around the shaft 11 and during each of said revolutions receives one of the sequence of colors and is each' time, and when arriving at the neutralizing bath roller 102, subjected to the latter`s drying action.

The machinery necessary to operate the gripping and releasing attachment for the sheets is not shown in the drawings and any of the well known devices suitable to accomplish this obj ect may be employed.

From the foregoing description it will be seen that the functions of the various cylinders and their adjuncts are positive and accurate in their action and that the object of the invention, namely, to provide a. simplified and accurate multiple color printing press with positive operation and of easy adjustment in all its component parts is thereby attained.

It becomes apparent that the cylinders or printing presses of this kind can be provided with any number of segment forms and a corresponding number of inking attachments, and that the number of segment forms on the paper cylinder must equal that number plus one additional segment form.

It. will also be apparent that the 4Style of the eylindera designated as paper cylinders in the foregoing epeeilieation can be applied to any other class of multipleprinting in avlnnel provided that such cylinder is en'- (flnn'lerentially `subdivided insegmental parte whirh in number exceed by one the i'orni and transfer cylinders, :segmental enbdivi sions, and where eueh subdivieionel on the paper cylinder or its equivalent eoineide in .enriaee extent with the Surface extent oi' the subdivisione of the forni and transfer cylinders, and is also equal to the latters perpberal speed.

The class of multiple printing machinery to which my System of multipleeolor printing can be applied embraces those used for dry plate printing, surface printing, either from plate or stone, textile printing or any other class of printing known to the graphie arte when used for Color printing.

Having fully deferibed my invention, what I elaiin as new and desire to Secure by Letters Patent, ie;-

In a niultiple-e0lor printing machine, a paper cylinder having segmental Surface Subdivieionel with interveninr open s aces which contain gripping attac inients a apted to reeeive and hold the sheets of material designed to be printed upon and placed on said segmental .Surface subdivisions, means for feeding the paper or other material in sheeta from a eontinuone paper or material roll to the paper eylii'ider, a sul'ipleinental roller placed so as to eon'ie in surface contat-t with each ol the printed sheets attached to the paper Cylinder a reeervoir for supplying nentri'tlizing and dryiiig solution to said supplemental roller, whereby the sheets of the paper are Subjeeted to the action of the neutralizing and drying Solution before receiving a Second eolor imprint7 Substantially as described.

In testimony that I elaiin the foregoing as my invention I have Signed iny name in preeenee of the subscribing Witnesses chie 18th day of .lune 1906.
