MACHINE FOR MAKING PRINTING-SURFACES.

SPECIFICATION forming part of Reissued Letters Patent No. 1 1,903, dated April 9, 1901.

Original No 662,864, dated lfcvemher 27,1900. Application for reissue filed March 5,1901. Serial No. 49,965.

To all whom, it may concern.-

Be it known that I, EDW'ARD llET'l, a citizen of the United States, and a resident of Newdorp, in the county of Richmond and State 5 of New York, have invented certain new and useful Improvements in Machines for Making Printing-Surfaces, of whiclrthe following is a specification.

This invention relates to machines designed for usein making printing-surfaces, and more particularly to machines adapted to. be employed to impose a design or plurality of designs upon a printing-form adapted to be transformed into a printing-surface for the design or designs. The printing-form when completed may be either planographic, relief, intaglio, or other character.

The invention seeks, among other things, to

combine in one machine mechanism whereby a design or plurality of designs may be imposed from a setting-up plate or other basic surface upon a printing-form and mechanism whereby the design or designs so imposed upon said printing-form may beimposed upon a second printing-form. For convenience the [irstnamed printingform will be herein termed the primary printingform, and when developed into a printing-surface it will be termed the primary printing-surface.

0 The second-mentioned printing-form will for convenience be termed the secondary printing-form and when developed into a printingsurface the secondary printing surface. In the preferred construction the design or designs are communicated from the primary priming-surface to a suitable conveying-surface and are then communicated from the conveying-surface to the secondary printing-form. The invention, however, in-

0 eludes Within its scope an arrangement Whereby the design or designs of the primary printing-surface may be com municatcd directly to the secondary printing-form without the intel-mediation of a conveying-surface.

In addition to the mechanism above referred to the in volition also seeks to provide means whereby the design or designs of the setting-up plate or other basic surface may i be imposed upon the primary printing-form in accurate predetermined position and a then communicated to or imposed upon the secondary form in accurate predetermined position and with reference to register in the ultimate use of the secondary printing-surface in its operation of printing.

The secondary printing-form is preferably constructed of predetermined size and shape, so as to accurately fit in a preestablished seat in the machine or transferpress and in a lished seat in a printingpress. It

prestabis rem 0vable from and replaceable in said seats, so that other secondary printing-forms may be mounted in said seats and accurately lit and work with the cooperating presses.

parts of said The printing-forms are preferably curved, so as to work in a rotary printing-press, and they are also preferably shell-ii ke, cylindrical, and tubular. The primary prin ting forms are preferably constructed so as to be identical in size and form with the secondary p rin tingforms and so as to be removable from and replaceable in a preestablished seat in the transfer-press and so that other primary printing-forms may be mounted accurately in the same seat in such press.

Of course it is not essential that the primary printing-forms shall be made so as to fit a prestal'rlished seat or seats in a printing-press unless such forms are to be used in printing.

It will be most economical, however, to so construct them with reference to a printing-press.

The basic surface or setting-up plate is constructed to accurately fit in a preestablished seat in the transfer-press and is removable from and replaceable therein.

The conveying-surface is also preferably removable and replaceable in a preestablished seat in the transfer-press, and in the simplest construction the same seat is employed for surface and for the conveyingsurface.

the basic the basic and the conveying surface, or either of them, might with some advantage be permanently mounted in the transfer-press, and such arrangement is within the scope of my invention.

The basic surface and conveyingsurface are both preferably flat and mounted upon a horizontal reciprocating bed or beds, the primary and secondary forms working by rolling contact with said surfaces The in- Both means whereby the design or designs may be ronfti n is not limited, however, in its broad aspect to a basic surface which is flat or reciprocatin g nor to a conveying-surface which is fiat or reciprocating. Either or both of thesesurfaces may be curved and either or both of them may rotate or be stationary. The invention is not in its broad scope lim ited to any particular form or shape of basic surface, of conveying-surface, of primary printing-form, or of secondary printing-form, nor is it so-limited to any particular charac ter of movement of these features in the operation of imposing a design or designs from one to another.

In the accompanying drawings, which form part of this specification, I have illustrated a machine embodying the various features of the invention in their preferrred form and also modifications.

Figure 1 is a side elevation of the machine in'its preferred form. Fig. 2 is a central longitudinal section of the machine shown in Fig. 1. Fig. 3 is an endelevation looking in the direction of the arrow in Fig. 1. Fig. 4 is a plan view showing the basic surface detached from the machine and mounted in its preestablished seat on the bed. Figs. 5 and 6 are respectively side elevations of a basic surface and eonveying-surface Figs. 7 and 8 are central longitudinal sections of modified forms of the machine. Fig; 9 shows a detail in section.

Referring now to the specific mechanism shown in the drawings, and particularly to Figs. 1, 2, and 3, the machine is provided with a suitable and substantial frame 1, which may be of any approved design, and on this frame is a bed or support 2, having thereon a removable and replaceable basic surface 3, preferably including a zinc or equivalent setting-up plateor transfer-base having fixed thereto the design or designs to be imposed upon, imparted, or transferred to the primary.

printing-form. The transfer-base in its best form is non-expausible and non-contractiblo', so that the design or designs fixed thereon are also nou-expansible and non-cohtractible under the pressure of the primary printingform, and thus the design or designs may be im parted to the primaryprinting-form. The transfer-base is generally of such thickness as to form. a rigid body, as shown. It has one side and one end made perfectly true, so as to acen rately lit in the preestablished seat formed on the bed 2, which seat is determined by the ribs "'1" and 5, against which the basic surface is forced by the nuts at and 5. The ribs 4 and 5, it will thus be seen, constitute guiding means, with reference to which the basic surface may be brought both longitudinally and transversely into the predett-u'miued position required or the preestablished seat. The design or designs of the basic surface are generally fixed thereto by being printed upon severai transfer-sheets stuck up on the transfenbase after the lithographic mztu' 1-. If desired, instead of always using the same transfer-base a series of transfer-bases may be employed and so constructed as to fit accurately in the same precstablished seat on the bed 2.

The bed 2, which is flat, as shown, reciprocates horizontally in the slideways 6, formed on the frame of the machine, being driven by the rotating screw shaft 7, which passes The screw-shaft 7 is driven in one direction to move the bed forward and in the opposite direction to move the bed backward by suitable mechanism. In the present instance I employ a main drive-shaft 9, on which is fixed a gear-wheel 1 0, geared to'the motor 11. On the shaft 9 is a gear-wheel l2, meshing with the gear-wheel 13, fast on the screw-shaft 7. The gear-wheel 12 is locked on the shaft 9 and unlocked therefrom by the clutch 14:, operated by the shaft 15. This shaft carries a clutch-operating arm 16 and also arm 17, having a slot which receives a pin carried by the hand-shaft 18. By operating the shaft 18 the wheel 12 may be locked and unlocked with respect to the shaft 9. The motor 11 is reversed to reverse the screw-shaft 7.

x 19 is a primary printing-form carried on the support 20 and from which it is preferably removable and replaceable. In its best form the primary printiug-form is continuous, cylindrieal, and tubular in form, the support being inv the form of a hollow cylinder and bodily removable and replaceable on the shaft 21, on which it is locked in place. The primaryprinting-form 19 is shell-like, as shown, and is provided with ribs 22 on the under side, which are adapted to enter corresponding recesses in the support 20, a marked rib in a marked recess, when the printing-form is slipped onto its support; The supportingcylinder 20 is provided with a circumferential shoulder 23, against which the printingform is adapted to accurately fit and against which it is pressed home and held by the clamps 24. The shoulder and the rib 22 constitute guiding means, with reference to which the primary printing-form and successive primary printing-forms may be lotransversely in a preestablished seat on the support and always in the same predetermined position. An'ycther forms of guiding ployed.

The shaft 2i, which carries the form-support 20 and the primary printing-form it), is movable up and down, so that the primary printing-surface may be brought into contact with the basic surface under suitable prea sure and so that it may be moved out of contact with the basic surface. For this purpose the shaft 2i is carried in the vt-u-tically moving bearings. One of these hearings (shown in dotted lines in Fig. 2) is an (.n'dinary square box movable 'in the slideway 25 on one side of the main frame. This box is connected with the pressure-arm '20. The other hearing is provided by complementary semicircuthrough the threaded nut 8, fixed to the bed.

cated accurately both longitudinally and means for this purpose may of course be em lar recesses formed in the arms 27 and 28, pivoted on the horizontal pivot 29, fixed on the sliding frame 30. The arms 27 and 28 move up and down behind the keeper-plate 31 on a shaft 32, which is fixed on the main frame and is provided with a worm-gear 33, operated by the worm-shaft- 34. When the, keeper 31 is down, as shown in Fig. 1, the arms 27 and 28 are thereby held firmly together against the main frame and in an up right position. The arms 27 and 28constitute a pressure-arm corresponding to theop posite pressure-arm 26. The shaft 35, worked by the hand-lever 36, carries eccentrics 37, which operate thepressure-arms; The main frame on the side of the arms 27 and 28 has an opening 38 large enough to permit the passage therethrough of the ,primary printing-form 19. When the printing-form is to be removed from the machine, the keeper 31 is moved upward out of the way of the arms 27 and 28. These arms are swung downward on the pivot 29. The cylindrical printing-form 19 is then slipped frourthe supporting-cylinder through the opening 38. In removing the printing-form I generally employ the apparatus shown and described in the patent granted to me November 21, 1899, No. 637,579, said apparatus being provided with an arm adapted to beheld in fixed alinement with the shaft 21, so that the printing-form 19 may he slipped from its supporting-cylinder upon said arm. The printing-form 19is equipped withinking and dampening devices, whereby the printing-form is rolled up in the operation of developingit into a printing-surface and whereby the primary printing-surface 19 may he inked for the purpose of communicating its design to the secondar printing-form.

39 is the main ink-distributing cylinder, fixed on the shaft 40 and communicating ink to the printing-form 19 through the usual inkdistributing rollers, which are carried in the swinging frame 4l,supported by the shaft 40. A hand Worm-shaft 42 operates the shaft 43, which carries gears 44, meshing with segmental gears 45, formed on the swinging frame4l. By operating the hand-shaft 42 the frame 41 may be moved so as to carry its inking-rollers to and from the primaryprinting form 19.

46 is a sliding frame carrying dampeningrollers 47 and operated by the eccentric-shaft 48, whose eccentrics 49 turn in boxes formed in the frame 46, the shaft being operated by the hand-wheel 50.

51 is agear-wheel working on a stud fixed. on the inside of the main frame and meshing with a gear 52 on the main distributing-cylinder 39 and with a gear 53 on the form-cylinder 20, so that the form-cylinder may be driven from the ink-cylinder 39. Movement is communicated to the inking-cylinder 39 from the main shaft 9 by the wormgear 54, meshing with a gear 55 on the shaft 51$,which carries a gear 57, meshing with a gear 58 on the vertical shaft5i), which carries a beveled gear 60, meshing with a beveled gear 61 on the shaft 40. The worm 54 is formed on a sleeve adapted to be locked on and released from the main shaft 9 by the clutch G2, operated by the shaft 63, which itself is actuated by the intnd-shaft (34,

In order that the basic surface may impose its design or designs upon the primary printing-form in accurate predetermined position, thc hed 2 is provided with a tooth 65, designed to mesh with a marked recess in the gear 53. Then the basic surface and primary printingform are cooperating, the printing-form is lowered,so that the tooth (i5 enters the marked recess, and thus the basic surface and printing-form may be brought into an accurate predetermined cooperating relation, which relation may be repeatedly obtained with the same or different primary printing-forms and with the same or different basic surfaces. The tooth 6-5 and marked recess constitute preestablished guides whereby this predetermined relation may be attained.

In the embodiment of the machine shown in the drawings the secondary prii'iting-form 66 is constructed, arranged, and mounted in identically the same way as the primary printiug-form 19 and is equipped with inking and dampening rollers of the same construction and arrangementas those for the primary printing-form. Only a brief reference to the secondary printing-form and its inking and dampening rollers will therefore be required. The secondary printing-form has ribs 67, which entercorrespondi ng grooves in the sup porting-cylindeiififl, which is provided with a circumferential shoulder at one end, against which the printing-form accurately fits when seated on its support. This circiunfcrential shoulder is not shown in the drawings; but it is similar to shoulder'23 on the primary printing-form. A marked rib 67 enters a marked groove in the cylinder (58, and these ribs and the circumferential shoulder constitute guides whereby the printing-form may be mounted in accurate predetermined posiiion both longitudinally and transversely on il's support. Swung from the shaft 70, on which turns the main distrilmting-cylinder 7.1, is the inking-frame 72, carrying inkingrollers 73-. The gear 74 on the hub of the cylinder 71 drives the idle gear 137, which meshes with and drives the gear 133 on the cylinder 68. The gear 137 is carried on a studl39. The inking-frame 72 is moved to and from the secondary printing-form by the hand-shaft 75, which actuates the shaft 76, carrying the gear-77, which meshes with the segmental gear 78 on. the frame 72.

79is the sliding dampening-irame, carrying the dampeningrollers and operated by the hand-wheel 80 on the shaft 81, which carries eccentrics 82, working in boxes in the frame 79. The main ink-distributing cylinder '71 is driven from the main shaft 9 by the wormsleeve 140, which meshes with the gear 141. on the shaft 142, carrying the gear 83, meshing with the gear 84 on the upright shaft 85,

this upright shaft carrying the beveled gear 86, which meshes with the beveled gear 87 on the cylinder 71. The worm-sleeve 140 is connected and disconnected with the shaft 9 by the clutch 88, operated from the shaft 89, which has the hand-shaft 90. The pressure-arm 91 carries one of the sliding boxes for one end of the shaft 92 of the cylinder 68, and the pressure-arms 93 and 94- carry the other boxes for the other end of the shaft 92, the arms 03 and 91 being mounted upon the pivot 95 and held in place by the keeper 96, which is operated bythe hand-shaft 97. The lever 98 turns the shaft 90, which carries the eccentrics 100, connected with and operating the pressure-arms.

The secondary printing-form 66 may be provided with a secondary set of inking-rollers adapted to apply a suitable preserving body or ink to the printing-form 60 aft'er-the-latter has been converted into a lithographic or In the par-' planographic printing-surface. ticular machine shown in the drawings these inking-rollers are mounted, arranged, and operated in the same way as the inking-rollers in the frames already described. 101 is the secondaryinkingframe for these -secondaryinking-rollers. ltis swung from the shaft 102, on which is loosely mounted the main ink-distributing cylinder 103, carrying a beveled gear 104, driven from the shaft 105, which is connected with and driven from the worm-sleeve on the main shaft 0, the arrangement of the gearing being the same as has already been described. The hand-shaft 107 actuates the shaft 108, operating the clutch 109 to connect and disconnect the screwsleeve 106 from the shaft '9. The gear 110 on the stud 111 meshes with the gear 76 and with the gear 112 of the cylinder 103, so that the main ink-distributing cylinder 103 drives the secondary printing-form (so. The studs 139 and 111 have square heads and are threaded in the main frame, so that the gears 137 and 110, carried thereon, can be drawn in toward the main frame and out of mesh with their. connecting-gears in order that each set of inking-rollers may operate separately in conjunction with the secondary printingform.

The hand-shaft 113 operates the shaft 114. to move the frame 101 to and from the secondary printing-form and in the same way and by the same means as the handshaft 75 and shaft 76.

The basic surface 3 preferably consists of a rigid backing 115, made of metal or other suitable material, and several sheets of thick paper'ilfi, which are smoothly placed upon and secured to the backing, said backing and the sheets of paper constituting the transferbase bearing on its uppcrsurface one or more designs. The bed 2 generally carries a yielding blanket or body which may be made of rubberand upon which the basic surface rests when in its seat upon the bed. Of course the face may of course be employed.

basic surface may be constructed in any other suitable manner.

. The conveying-surface 117 generally consists of a rigid backing 119, carrying on its upper surface a thin rubber sheet 120 and upon which thedesigns are to be imposed. Various constructions of the conveying-sur- \Vhere rubber is used, as just described, the designs imposed thereon by the primary printingsurface may be eifaced andthe same con.- veying-surface may be used repeatedly. I might, however, stretch a sheet of paper on a suitable base, and said sheet of paper, when the design or plurality of designs of the primary printingsurface have been imposed thereon, may be bodily turned over upon the *secondary printingform. In such cases a new sheet of paper would necessarily be used in each separate operation, because the designs would not be effaceable from the paper.

The operation of the machine is as follows:

The basic surface being mounted in its pre- I established scaton the bed 2, the bed is moved forward by the motor 11 beneath the primary form 19, which is lowered to bring the tooth 65 on the bed into mesh between the marked tooth onthe gear The bed is then moved forward with the basic surface and printingform in contact, suitable pressure being applied to this contact by the pressure-arms 26, 27, and 28. The printingform is thus made to rot-ate in rolling contact with the basic surface, which imparts the designs thereon to the printing-form. If the designs for the basic surface are on separate transfersheets, as shown in Fig. 1, these transfei sheets w"l be turned over bodily upon the printing-form and the designs imposed upon said printingform. Thus the designs are imposed. upon the primary printing-form in accurate pre determined position and with reference to register. Bed 2 is then moved b: ch out of the way and the designs on the printing-form dcveloped and made permanent. This may be done by etching and rolling up after the lithographic manner, or the development may be in accordance with-any other method of trea ment. Ifdesirerhafter thelithographic method of development has been resorted to the prin ting-form may be routed out or depressed. This development of the printinglnrm may be done apart from the machine; but the inking and dampening rollers carried in the frames 11 and 16, respectively, are intended in the machine shown in the i'lrawii'igs to be employed in rolling up the printingform, so that tho printing-form may be developed in thelithographic manner without withdrawing it from the machine. The primary printingsurface having been developed in suitable" as the seat for the basic surface 3. The bed 2 is then broughtinto contact Withthe primary printingsurl ace, the teeth 65 being first entered in the marked recess of the gear As the bed moves forward the design or designs of the primary surface are imparted to the conveying-so rfaee in accurate predetermined position both longitudinally and transversely. The secondary printing form 66 is then brought down u pen the eonveyitic-surface, the teeth (35 entering the marked recessin the gear 76, and the design or designs on the conveying-surface are i mparted to the secondary printing-form. The bed 2 is then moved back out of the way, and the secondary printing-- form isdereloped intoaprinting-surfaceof the character desired. In carrying out this development the inking and dampening rollers carried in the frames 72 and 79, respectively, are employed in the manner well understood, the inking-Frame 101 having been moved out of the Way. After the secondary printingsu rface has been developed it is then rolled up by means of the secondary inking-rollers in the frame 101, which are employed to apply to the printing-stn'face a suitable preserving body in the manner and for the purpose described in my pending application for rolling-up machine, Serial No. 709,877, filed March 21, 1899. This preserving body, which is preferably a light-colored ink, serves to preserve the design, especially when the printingasurface is to be stored some time before use, and need not be washedotl' ot' the printing-surface before using the printingsurlacc in the operation of printing". The dampeninn-rollers in. the frame 79 are used in conjunction with the secondary inkingrollers. treatnu-nt of the secondary printing-form in converting it into a printing-surface and in subsequently applying the preserving body may b'o carried out apart from the machine. A series or" duplicate secondary printing-surfaces may thus be made from one primary print in surface. A series ofserondary print-- lug-surfaces may also be made which have component designs adapted to register in printing. In this latter case a series of pri 'lnarysurfaceswould be first made having component designs.

The primary and. jecoi'ulary printing-terms are driven by Frictional contact with. the basin surface or eon. eyingsurt;- icon the bed 2; but, if desired, they might be driven by some suitable lorn'i oi gearing in accurate unison with said sin-Yams.

In Fig. 7 is shown a machine similar to that lllllSl/i'Hdt l in Figs. l, 2, and 3, except that there are separate beds for the basic surface and l'ortlie conveyine -surface. 2 istile bed or support for the basic surface 23, and 2 is the bed or support for the conveying-s11rlface .117. These supports are moved bark and l'orth by the .serewsltai't. 7, driven from the main shaft ll, and instead of liZt-Vlitfi nuts per manenily 'UHIH 'lJHl with the seren -shalt 7,

Of course, if desired, the entire.

like the nut u of bed 2 in Fin. 1, they have threaded split

sleeves

8 and 8, adapted'to be connected and disconnected I from the screw-shaft 7, so that the beds can be moved back and forth separately and independently. The split sleeve 8 is shown in detail in, Fie'. U. The upperside oi the sleeve is dovetailed in a transverse slideway 121, carried on the bed 2, and the two parts of the sleeve are made to clutch and nnclutch the screw-shaft 7 by the screw-shaft The bed 2 has a tooth 65, and the bed 2" has a tooth 65 these teeth entering marked recesses of the gears for the primary and secomlary forms, respec-' tively, for the same purpose as the tooth 65 on the bed 2.

In Fig. 8 the machine is arranged so that the primary printing-form 19 after having received the design or designs from the basic surface 3 may impose the design or designs directly upon the secondar' printing-form without the intermediationof a convoying-surface. The bed 2 is moved back and forth by the screw-shaft 7, and the primary printing-form is brought down under pressure upon the basic surface After the primary printing-form has been developed into a printing-surface the primary and secondary printing-forms are brought together in operating contact. For this purpose either one or both of the forms may be moved. As shown in Fig. 8, the secondary form 66 only is moved,

being supported in sliding boxes arranged to' move back and forth in horizontal slideways in the main frame by arms 123 and 124, the latter of which is not shown. The outer ends of these arms are threaded and carry Wormwheels l25and l26,the latter not being shown, the arms passing through threaded hearings in the main frame. by rotating the handshaft 127 the arms 123 and 124 are moved back and forth, so that the printii'ig-forms may be separated or brought together in com tact under proper pressure. The secondary printingiorm carries a gear128, which meshes with an idle gear 129, which meshes with a gear i 30 on a shaft 131., carrying a worm-gear 1232, meshing with the Worm-sleeve 12-53 on the drivingshaft. The gear 129 is carried on the pi ot of the toggle 134, whose outer ends are pivoted, respectively, on the shaft 131 and on the shaft of the secondary pri n ti ng-l'orn1. The Worm-sleeve 133 is made fast and loose on the drive-shaft by the clutch 135. By means of the toggle Iii-t and the connecting-gearing the secmidary form may. be driven, notwithstanding its change of position in the main frame. The primary and secondary forms may be driven together by frictional contact or by suitable gearing. In order that they may be always brought into proper andpredetermined cooperating relation, the marked recess 136 on the support of the form 19 is brought into mesh with a marked tooth on the gearing 128. The bed 2 has a tooth adapted to enter the marked rccess'l-lo, so as to provide a guide with reference to which the basic surface and primary printil'ig-form may be brought into accurate predetermined cooperating relation.

If desired, both the basic surface 3 and the conveying-surface 117 in Fig. 7 and the basic surface 3 in Fig. 8 maybe permanently securedto its supports. In this case the designs will be imposed upon the base of the basic surface whih .11 place in the machine.

\Vhile I have shown the various features of the invention in the best forms now known to me, it will be understood that variouschanges may be made in the form and arrangement of the parts embodying the invention.

So far as I am aware I am the first to provide a machine by means of which a basic surface may be employed to impose a design or designs upon a printing-form or primary printing-form and the said primaryprinting-form be employed to impose its design or designs upon another or secondary printing-form, and I wish to claim the sameherein broadly; also, in connection with guiding means whereby the design 01' designs may be thus imposed upon the secondary printing-form in accurate predetermined position and with reference to register.

The method in accordance with which and the mechanism whereby the design or designs are imposed upon the printing-forms 19 and 19 are shown and described in the patents granted to me November 21, 1899, Nos. 637,555 and 637,556. The method with whiclrand the mechanism whereby the design or designs areimposed upon the print- .ing-forms 6G and 60 areshown and described in the patents granted to me November 21,

1899, Nos. 637,595, 637,596, and 637,590. Ret'-.

erence is now made to those patents for a more detailed description of the method and apparatus referred to.
