Specification of Letters Patent.
Patented J m, 1912.
Application filed December 30, 1905. Serial Ito/293,928.
To all whom it may concern." Be it known that I, GEORGE E. PANCOAST, a citizen of the United States, and a resident ofNew York city,jborough of Brookof New York, have invented certain new and useful Improvements in Printing-Presses, of which.
' different assemblages of the same parts.
the following is a specification.
Myinvention relates to printing presses; and while as to some of its features it may be "applied to presses of various kinds, it is more particularly directed to rotary presses having a plurality of printing couples for printing on one or both sides of a web or a plurality of webs.
My invention has for an object to provide a construction whereby the parts or elements'of' a press may be arranged in various operative or physical relations, as may be required, to produce the' desired size or character of product or to produce a press of a desired shape either with respect to the spaceavailablefor its location or with respect to the accessibility of its parts or with respect to both considerations.
More particularly my invention has for an object to provide a set of press elements which may-be duplicated and assembled in various operative or physical relations to ties andto. enable the form to be a ed to the size or capacity.
These and other objects of the invention "fully explain'ed'herein. p Q My invention consists in the novel parts, "improvements, combinations, and arrangements herein shown and described.
i .In the accompanying drawings, which are referred to, herein and form a part hereof, are illustrated several, embodiments and modifications of the invention, the same serving in connection with the description hereinto explainthe principles thereof.
Of the drawings Figure 1 is a side elevation illustrating certain press elements" constructedin accordance with some of the Y features of. my. invention, somej-partsbeingdiagramma cally "indicated and others broken aw'fayto more clearlyillustrate the 9 construction. "Fig. 2 isf-"a diagram, ,1] ,lus-- 1 trating. an assemblage of the parts diflerent from that shown in F1g.. 1. Fig. 3 is. a
transverse section, of one of the elements shown in Fig. 1. Fig.4 is a plan view of 'nism element B.
produce presses of numerous forms or ca aciapt.
'- coupl will in part be obvious and in. part be more Figs. 9 and 10 are similar views, illustrating two forms of presses that may be produced by a set ofelements, one of which differs from the'corresponding element of the set shown in Figs. 1 to 5, inclusive.
Inaccordance with the embodiment of the invention. illustrated in Figs. 1 to 5, inclusive, two standard press elements are provided, the same being so constructed that duplicates of them may be assembled in various. Joperativerelations 7 to. ,produce presses. of numerous forms and capacities. The setof elements shown comprises aprinting couple element A and an inking mecha- {In accordance with one feature of the invention, the printing-couple element A-.is so constructed. that duplicates of it may be asseni led-with the parts and particularly the printing couples in various operative relationsas regards the'distance-between adjacent couples, either the linear distance between the correspondmg members of the ber, having-reference to the plane of the couple.
;'As shown, the print1ng couple" element or the linear orangular distance between the planesof. the couples. It is, in 'accordance with a feature of the invention,
comprises ampressionand design cylinders 1 and 2, respectively, and a frame in which said cylinders are mounted in cooperative relation. This" frame may vary as, to its shape and constructionbet-ween wide limits. As shown, this frame comprises a pair of side members 4 and 5, the same being, preferably, and as shown, substantial duplicates of eachlother'as to sha except that they may The side members 4 and e rights and.lefts. 5 may be secured togetherin anysuitable way. As 'shown,
they are secured together by atransverse e and construction I girder 6 whichis rigidly bolted at its opposite ends to the side frames. two of these girders may be employed, one on either side of the printing couple. Preferably, however, only one girder. is employed, the opposite side of the frame being securely stayed when assembled in a press by being'attached to an adjacent printing couple element or some other part of the press. In accordance with one feature oft-he inventlon, however, provision is made for the attachment of the securing means for the side frames invarious positions. As shown,
see Figs. 3 and 5, the'frames of the element are drilled and tapped on both sides of the couple so that the girder. 6 may be secured in either-of the two positions, as may be,
foundconvenient or desirable, when assembling the elements in a press.
In order that the printing couple element may be assembled in a press with the'printing'couple various operative or physical relations to other parts of the press, the side frames 4 and 5 are providedwith a plurality of seats or surfaces by means of which the element may be assembled and secured in I place in the, press. In accordance with the preferred construction and as illustrated, the frames are provided with two surfaces 7 and 8 whereby the position of the element may be fixedwith relation to other parts of the press, said surfaces preferably being locatedat a suit-able angle with relation to each other and at the same distance from theaxis of theimpression cylinder of the couple and at the impression cylinder, end of the frame so that the element. may be secured in place in different positions with respect to the angle which the plane passing through the axes of-the cylinders bears to the horizontal or to the corresponding planes of other couples. The particular angle which the surfaces 7 and 8 bear to each other, as shown in the drawings, has been found to be a convenient angle.
Theside frames, in accordance with another feature of the invention, are provided adjacent to the design cylinder with a'plu-i rality of surfaces'by which the attachment of the inking mechanism element in various operative relations to the design cylinder is facilitated. As shown, the frame is pro vided at this end with three surfaces 9, 10, and 11, the surfaces 9 and 10 preferably bearing substantially the same angle to each other as the surfaces 7'and 8, while the sur-' face 111 extends transversely to the plane which passes through the axes of the cylinders. These surfaces are preferably, and as' shown, located. at thesame distance from the axis of the design cylinder so that the inking mechanism will be in proper opera tive relation with the design cylinder in any one of thethree positions. As a matter of convenience and with the object in view of If desired,
1 and replaced in the frame.
making the side frames 4 and 5 as small as possible, a pair of brackets 12 and 13 is provided to give the surface 11- ample extent to enable the inking mechanism to be firmly secured in place, said brackets, when used,
being secured upon the surfaces 9 and 10,
as indicated.- The brackets 12 and 13 are also used to supplement the surfaces 9 and 10 when the inking'mechanismis secured to one of said surfaces, the bracket 13 being used in connection with thesurface 9, as indicated in the 2, and the bracket 12, being used in connection with the surface 10 when the inking mechanism is secured to the latter surface, the bracket 12 or 13 in each case being secured upon the surface 11.
The cylinders of theprinting couple may be secured in place in theframe in any suitable way. Preferably, however, provision is made to permit the cylinders to be removed from the frame without removing the frame from a press in which it may beassembled, To this end, the side frames 4 and 5 in the embodiment of the invention illustrated in Figs. 1 to 5, inclusive, are provided with slots 14', 15 so that the cylinders together with their bearings can be removed The box bearings 16 of the cylinder 2 may be rigidly held I in the slots 15in any suitable way, as by filling pieces or brackets 17, which, 'as shown,
are bolted in the slots 15 and form parts of the supporting surfaces 11 for the inking mechanism.
The bearing boxes 18 for the cylinder 1 are adjustably mounted sothat the pressurebe tween the cylinders may be regulated, and
preferably means are provided also for ef-- .ends of the slots 14 and are adjustably con nected with the-piece 20 by means of the set screws 24 and retaining bolt 25. The eccentrics 19 may be operated in an y suitable way. As shown, they are provided with arms 26' which are connected by links 27 to cranks 28 fixed at thev opposite ends 'of a shaft 29 whichextends transversely through a the printing couple frame and thus forms a common operating mechanism fo1; .the eccentrics at the opposite ends of the lmpression cylinder 1. Theshaft 29 may be driven in any suitable way. Preferably, and as,
shown, it is provided at each end with a As shown, the boxes 18 are mov- 8 naled .on the side frames 4 and 5 and have provision for engagement by a suitable wrench. To facilitate the attachment of the printing couple element in various positions "with relation to other elements or parts of the press, the printing couple frame is preferably so constructed that the operating shaft 29 may be mounted on either side of the printing couple and so that the driving pinion 31 may be located on either side of the shaft 29 in either position. To this end,
the frames 4 and 5 are provided with suitable bearings 29". for the shaft 290m both sides of the printing couple and also with bearings 31 for the pinions 31 on both sides of each of the bearings 29, all as clearly shown in Figs. 1, 3, and 5.
The inking mechanism may be of any suitable construction and it may be provided with any suitable form of frame. which is adapted to be secured in the variouspositions provided for its reception on theframe of the printing couple. As shown, the inking mechanism comprises a fountain 32, a fountain roller 33, ductor 34, distributing cylinders 35 and 36, soft distributing and conveying rollers 37, metallic riders 38, and form rollers 39. The parts 32 to 37, inclusive, as shown, are mounted in the frame comprising side members having attheir bases suitable lugs or flanges 41 by which they may be secured to any one of the sur faces 9, 10, and 11 of the printing couple element. In accordance with the construction shown, the riders 38 and form rollers 39 on each side of the inking mechanism are mounted in auxiliary frames 42 which are pivotally mounted on the side frames of the printing couple elements and are provided with suitable connections 43 whereby they may be moved so as to carry the form rollers into and out of operative relation with the design cylinder. In order that theframes 42 may be securedin the several positions corresponding to the several positions of the ink frames 40-, the side members 4 and 5 are.
provided with a series ofsuitably spaced openings42 adapted to receive the pivots of the frames 42, as shown in Figs. 1, 2, and5. The inking mechanism may be driven in any suitable way. In the particular em bodiment of the' invention illustrated the inking mechanism is driven from a gear 44 on the shaft of the design cylinder 2 by a gear 45 which meshes with pinions 46 on the shaftsofth'e rollers 36, the otherparts of the inking mechanism being suitably geared with one or the otherof the rollers. "In or- (l('l' that the driving connections for the ink;
ing mechanism may not be disarranged or require adjustment for the various positions the design cylinder, the surfaces 9, 10, and 11 are preferably arranged equidistant from the axis of said cylinder, as shown;
The printing couple together with its inking mechanism. may be driven in any suitable way, as by a bevel gear 47 fixed on the shaft of the cylinder 2, the two cylinders of thecouple being geared to rotate in' unison by means of gears 48, the latter preferably being split .asindicated in Fig. 4, and the;
'parts made adjustable with'relation to each other. to take up backlash.
It will be observed that duplicates of the elements shown in Figs. 1 to 5 may be as-' sembled in various relations to produce presses having differentforms and capacities, suitable frame mechanism being provided to support the assembled elements in the desired relations. v
In Fig. 6 is diagrammatically illustrated a convenient manner of "assembling the elements to form a web perfecting press. In this construction the printing couple elements A and A are employed, the same being secured together with the surface 7 of one in contact with the'surface 8 of the other so as to bring their impress-ioncylinders' into a close relationship and to separate the design cylinders to aflord ready access to the same. The inking mechanism elements B and B are secured to the elements A and A respectively, at the surfaces 11.
'of the inking mechanisms preferably being I supported and steadied by a pair of frame elements, one of which is indicated at 52. The elements A may be more firmly united by means of brackets 53 and 54. The printing couples may be driven in unison by any suitablemeans. As shown, a vertical drivmg shaft 55, recelvlng power-from any suitable source, is directly geared by suitable bevel gears with the shafts of the design cylinders. I v
'The'press illustrated in Fig. 7 includes three sets of elements arranged to print two colors on one side ofa Web and one on the other. Two of the printing couple elements A and 'A are arranged one above the other with the suigface '8 of one facing the surface 7 of the other so that the planes of the printing couples are at an angle to each other as in the form of press shown in-Fig. 6; but in this case the two elements are separated by a'web forwarding anti-offset mechanism 56, which with. its frame may form a third standard element 0 ofpress contact so that these two printing couples will bear a different relation toeach other from that which the couples of elements A and A bear to each other, this arrange-- ment being a convenient one for the type of press shown both as regards the lead of the web and as regards the accessibility of the 7 parts. In this construction each of the ink- Y element 67 corresponding tonne of the web.
ing mechanism elements 13, B and; B is secured to the surface 11 of the corresponding printing couple element.- The-frame construction of this press comprises a base 57, standards 58 and 59 for support-ing the outer ends of the inking mechanism elements B and B frame sections'60 and 61 for supporting the printing couple elements from the base, and suitable braces 62, 63, and 64:. The driving mechanism shown comprises a vertical shaft 65 which receives power from any suitable source and isgeared by miter gears to the design cylinders of the elements A and A?. The printing couple of theelement A is'driven from that of A by means of atransverse shaft 66 which-is connected by bevel gears to the de-' sign cylinders of the two couples.
The pressshown in Fig. 8 is adapted to print four colors on one side of the web and one on the reverse side. Of the five printing couple elements employed, the first four A A A,-and A are assembled with the surface 7 of one facing the surface 8 of the other, these couples, as'shown, being separated from each other by a. series of web transferring elements C C and Q By reason of this arrangement the impresslon cylinders ofthe couples are located substantially in the arc of a circle and in such relation to each other that they may be easily reached from the central space which is provided by the arcuate form of the press. 'At the same time the'design cylinders are suitably separated and readily accessible. The element A is located below the element A with the surfaces 7 of the two elements facing each; other but separated by a frame transferring elements C.
The inking mechanism elements may be variously arranged. As shown, the inking mechanismelementslfl and B are secured to the surfaces 11 of the "corresponding printing 'couple e'lementsA and A and the inking mechanism elements 13*, B and ,B? are secured'to the urfaces 9 of the printing couple elements A, A, and A, respectively.;J The inking mechanism element B v sois shown asforming a support for the printing couple element A and theparts superimposed thereon. The frame of this ,press comprises a base'68'and frame members 69,
70, and 71.- The printing couples may be .tical driving a suitable power shaft 73, and the other couples are driven from the first couple by means of a master gear 74 which is suitably mounted in concentric telation with the severalimpression cylinders, of the first .four printing couples. The last couple of the series is driven from the gear74: by-a pair of intermediate gears 75 which mesh-with the gear on the design cylinder of the couple.
In Fig. 9 a somewhat different form'ofprinting couple elementD is illustrated. In
accordance with the construction shown,
each' of the side frames of the element is provided with four surfaces 76, 77 78, and 7.9, adapted to beused in securing the couples to each other or to other parts of the press in various operative relations and to ,surfaces' 80 and 81 by means of which'the inking frame elements E may be secured in twodiflerent operative relations to the designcylin'ders of the couples. In the arrangement'shown the two upper printing couple elements D and. D are. assembled with the frame surfaces 78 and 77 respec-;
tively, in contact; the elements D and D with the surfaces-79 and 76, respectively, in contact; the elements D and D with the surfaces 78 nd 77,-respectively, in contact; the elemen' s D and D with the surfaces 79 and 76, respectively, in contact; andt-he ele- -ments-D*'and D with the surfaces 78 and 77, respectively, in contact. The inking mechanism elements E, E and E are secouple elements D and D and braces 83 are provided between the elements D and D and D and D respectively. One or more webs may be fed to this machine and receive one or more impressions on either or both sides. As shown, the printing couples of the respective pairs of elements D, D and D D D ,.D act each to print and perfect a slngle web, the web supply rollers 1 84, 85, and 86 being suitably supported upon a standard 87. The printing couples may be driven -1Il any suitable way, as by the verand D In Fig. 10 is illustrated a press for printing fourcolors on one side of a web, the
shafts 88 and 89 which are re- I spect1vely geared to the impression cylinders of the'couples D, D D, and D D same being "formed by a suitable arrangement of the printing couple elements D and tlt'e' inking mechanism elements E'. In this press the printing couple elements D D cross, the adjacent ends of the elements be- D, and D are arranged in the form of a nism elements E and E are secured to the uppermost surfaces 80 of the elements D and D and the inking mechanism elements E and E are secured to the lowermost surfaces 81 of the elements D and D*,-respectively, said inking frame elements in this instance forming the main support for the other parts of the press. This press may be driven inany suitable way, as by a master gear 90 from which the impression cylinders of the printing couples are directly driven, said gear 90 receiving power from any suitable source, as from a vertical shaft 91 and suitable gear connections. Other forms, of. printing press elements and other arrangement-s of the forms of elements shown will readily suggest themselves to those skilled in the art, the principles and advantages of the invention once being unders'tood.
