ART oF MAKING PRINTlNe-SURFACES.

- SPECIFICATION forming part of `Letters Patent No. 637,595, dated November 21, 1899.

Application filed October 4,1899. Serial No. 732.439. (No model.)

To @ZZ whom, it may concern:

Be it known that I, EDWARD HETT, a citizen of the United States, and a resident of New York, (NeWDorp,) in the county of Richmond and State of New York, have invented certain new and useful Improvements in the Art of Making Printing-Surfaces, of which the following is a specification.

This invention relates to a newand useful improvement in the art of making printingsurfaces suitable for planographic, relief, intaglio, or other printing:

In that branch of the art to which my invention is most nearly related it has heretofore been the practice in making printingsurfaces to lirst make a basic surface by sticking up by hand and with great care a number of transfers upon a flat support called a setting-up plate. These transfers are usually thin pieces of paper bearing copies in black ink of the design or matter to be printed by aprinting-surface. The designs on the transfer-paper are generally printed thereon and without any special reference to the absolute or relative location of the designs on the various transfer-papers. Where several printing-surfaces are to cooperate in printing, as in multicolor-Work, it is essential that the transfers for each printing-surface be -Very carefully stuck upon the setting-up plate in accordance with certain matching guidingmarks previously located on each transfer when the transfer is made and on the settingup plate with reference to the register of the printing-surfaces Which when completed are to cooperate in printing. When a basic surface has been thusA prepared, it has been the practice to lay it upon the surface, generally a dat stone, which is to become the printingsurface. Scrapers are then passed over the setting-up plate, so as to exert proper pressure, and, the setting-up plate being removed, the transfers are found turned over from the setting-up plate upon the stone. The transfer-paper is then soaked off, but the ink of the transfer remains on the printing-surface, and the surface is then developed, as by etching, and thus ,becomes a printing-surface. In cases where itis necessary to employ a plurality of printing-surfaces in printing a job it has been the practice, according to this old process, to make each of the printing-surfaces in the same way, starting always with the setting-up plate and the transfers turned over therefrom upon each surface to be made into a printing-surface. Whatever may be the number of printing-surfaces required for a job, it was necessary to form each in the same way from its particular basic surface previously prepared and with the same painstaking care, especially in regard to accuracy of register. Again, where in some cases it was desired to duplicate the printing-surfaces, so that those Worn out might be replaced or so that the printing might proceed on dierent presses at the same time with duplicate printing-surfaces, it was necessary jtoiorm these duplicate printing-surfaces ezh in the same way and always from a new and original basic surface previously prepared and each with the same expenditure of care, time, and labor. Thus the making of the printing-surfaces added greatly to the final cost of the j ob, and this cost increased in proportion to the number of printing-surfaces required.

The invention consists in its generic aspect in the process of making a printing-surface, Whether planographic, relief, intaglio, or otherwise, from a previouslyprepared printing-surface, Which for convenience may be here called a primary printing-surface or a primary surface, by printing from saidprimary surface-that is, taking an impression in any suitable manner from said surface-directly or indirectly upon or to a surface adapted to be developed into a printing-surface, said bodies or couple being arranged in a definite and predetermined cooperating relation both longitudinally and transversely with reference to prestablished guides, for the purpose hereinafter explained. The surface which thus receives the design from the primary surface I herein for convenience term the secondary surface, and when developed the secondary printing-surface. By the use of the prestablished guides or guiding means, which may vary widely in character and arrangement, the design of the primary surface may be located on a secondary surface in an exact predetermined position both longitudinally and transversely and also with reference to register, and from a series of registering primary surfaces a series or a plurality of series of regis- IOO ftering secondary printing-surfaces may be made.

Y t in a prestablished seat in a printingLpress,

lmaking the primary surface, preparing fort this purpose a basic surface, preferably by sticking up ordinary transfers bearing the `design to be printed upon a setting-up plate -and turning over these transfers in the usual so that they may be mounted at once in place in the press and without any special adj ust-V ment for register be made to print in accurate register.

'It' also consists in various steps and com-j binations of steps conducive to the desired result and of more or less particular advantage, as will hereinafter appear and be set out in the claims. d

In carrying out the process I may begin with a primary surface made by any suitable process or mayand generally do begin, as a preliminary tothe present process, by'rst way upon-a printing-surface, which is then suitably developed and becomes the so-called primary surface. This primary surface may be of stone, zinc, aluminium, or other suitable material and may be developed so vas -to be a planographic, relief, intaglio, or

in a machine in which the process of imparting -other printing surface. The primary surface is generally graduated--that is, the design thereon is so made as to be capable of printf ing .an impression in which the ink will be distributed on the impression-surface in graduatedquantities for light' and shade effects, `depth of color, &c. The primary surface and y secondary surface are then arranged in a definite and predetermined coperating relation, so that the former works as required with reference to the latter and with reference to the position which itis desired the design of the v'primary surface shall occupy 'on the secondary surface when imparted thereto. For this purpose the primary surface and the secondary surface are arranged in prestablished seats'on suitable supports prepared for them the design of the Vprimary surface to the secondary surface is most conveniently carried ont, the preestablished guides being employed for quickly and with absolute accuracy arranging the primary and secondary surfaces vin their proper ycooperating relation. `The linked design of the primary surface is then y carried over from the primary surfacean'dimparted to or upon the secondary surface directly or indirectly, but without the inter-mef diate employmentof a setting-up plate. The

'secondary surface is then developed, so as to become a printing-surface, and is then the socalle'd secondary printing-surface.

The secondary surfaces are made of a permanent size and shape to adapt them to Like Y Athe primary surface it'may be of stone, zinc, aluminium, `or other suitable material and. may-be developed so as to be a planographic, relief, intaglio, or other'printing surface,"a'nd the development of the secondary surface. vmayor may notbe in accordancewith the method employed in developing the primary.

surface. For example, the primary lsurface may be arelief or intaglio surface and ythe secondary surface may be so developed as to be a planographic surface, or vice versa. Neither the character or material of one of thesesurfaces, whatever it may be, has any necessary dependence upon the character or primary surface maymteddirectly upon a conveying-surface, which is then brought into cp'I Ijjf''t'w the'conveyin'g'jsu'rface beibnganintermediate between 'theprimary surface andthe secondl lary surface and .beinga basic surface for the secondary surface, or the primarysurface may be made toprint directly upon the secondary surface, lin which case the latter'sur- -face when developed wouldvprint Athe-same design as the primary surface, Vbut in reverse. VIn cases where an intermediate conveyingsurface is employed it may, as preferred, be

in the'form of a fabric, as transferpaper, stretched over a suitable support "and be `brought into firm contactwiththe secondary surface and turned over thereupon, or the yconveying-surface may be a sheet of paper,

rubber, or other suitable material and Vheld `on a vsupport from which the conveying-surface is lnot separated when such surface is broughtinto contact with' the secondary sur `face,but which remains rmlysecured on its .support duringthis operation.' When the `conveying-surface is of paper and whether it is held on its support yduring the operation of imparting the design to the secondary surface or is turned over from itsA support upon the secondary surface, new or successive `conveying-surfaces must take the, place onvthe ,supe Vport of the one used and preferably the iden- "tical place in imparting thev design to new or successivesecondary surfaces. -v When the lconveying-surface is of rubber or some other material admitting of repeated use, it is permanently held on'its support, the ink residuum, if any, beingl washed off or otherwise 1removed before beginning its work vfor each -new 'and dierent design to be imparted to a vsecondary surface.

AI preferably-employ a conveying-surface in carrying over and imparting the design to the secondary surface,the conveying-surface gen- 1erallfy being of transfer-paper, and `afterrenceiving the design from the primary surface `being turn-ed over-upon the secondary surface. The secondarysurfaces are preferably identical and interchangeable, especially where IOO IIO

they are to carry the same design, and Where they are to carry different designs intended to cooperate in printing, as in multicolorprinting, they are designed and constructed for register when completed as printing-surfaces. In using the conveying -surface in practice it is mounted in a machine with the primary surface and the secondary surface, the primary surface and secondary' surface being arranged in a definite and predetermined coperating relation both longitudinally and transversely, and preferably in the same or equivalent definite and predetermined coperating relation both longitudinally and transverselyrwith respect to the conveying-surface and with reference to preestablished guides. For this purpose I mount the conveying-surface and the coacting primary and secondary surfaces in the machine each in its own separate assigned place orpreestablished seat. The secondary surface is made removable, so that successive secondary surfaces may be arranged in the same place, and thus be arranged in the same relation with respect to the conveying-surface or successive conveying-surfaces and receive identical designs from the same primary surface, and when the secondary surfaces are identical the identical designs im parted thereto Will be identically placed, so that these secondary surfaces may be interchangeable in the subsequent printing. The same result may be attained, however, by imparting a design toa secondary surface mounted in the machine in the particular` place assigned for it and then mounting the neXt secondary surface in the same place occupied by the primary surface, the primary surface having been previously removed after having printed its design on the conveying-surface. In this case the two successive secondary surfaces are arranged not in the same but in equivalent deiinite and predetermined cooperating relation with respect to the successive conveying-surfaces. In making a series of registering secondary printing-surfaces designed to cooperate in printing each secondary surface,being constructed and designed for register, and its corresponding primary surface are arranged in the same or equivalent detinite and predetermined cooperating relation with respect to their conveying-surface. Moreover, in making a plurality of secondary surfaces from the same primary surface, whether through the intermediation of a conveying-surface or successive conveying-surfaces or not, the successive secondary surfaces are arranged in the same or equivalent cooperating relation with respect to the primary surface. After the secondary surface has received its imprint of the design from the primary surface and has been developed in suitable manner it may then be inked, mounted in a press, and used as a printing-surface. Thus it will be seen that the printing-surface-viz., the secondary printing-surface-is made or derived from a previously-prepared.

printing-surface-viz., the primarysurface* and Without the intermediate employment of a setting-up plate, which after the primary surface has been made has no further utility. It Will also be seen that two or more secondary printing-surfaces may be derived also from the primary surface, and two or more secondary printing-surfaces, or one or more such surfaces with a primary surface, constitute a plurality of printing-surfaces adapted to be used in printing the same design. This plurality of printing-surfaces for the same design is very useful in cases where it is desired to run two or more presses upon the same job or when one or more extra printingsurfaces are required to take the place of a printing surface orsurfaces which have been Worn out or becomeimpaired by use in printing or otherwise. This plurality of printingsurfaces capable of indefinite multiplication or increase makes it possible, moreover, to print from such surfaces the same design indenitelyand beyond the limit of Wear of an individual printing-surface. Again, from a series of registering primary surfaces a series or a plurality of series of secondary printingsurfaces adapted to coperate in printing may be readily made, the designs being imparted from Vthe series of primary surfaces to each series of secondary surfaces in accurate and predetermined position and with reference to register as printingsurfaces, and each secondary surface of a series may be made identical and interchangeable with the correspond` ing members of the other series. Moreover, much time, labor, and painstaking care are saved by the new process in preparinga plurality of printing-surfaces as compared With the old process of preparing each printingsurface directly from a manuallyprepared basic surface.

In the practical use of the invention a plurality of designs is imposed upon the primary printing-surface in accurate predetermined mutual relation with reference to the printing of those designs by the secondary printing-surface in accurate predetermined positions on the impression-surface and with reference to register. Thispluralityofdesignsisgenerally imposed upon the primary surface by sticking up a plurality of ordinary transfers upon a setting-up plate in accurate predetermined mutual relation which they are to have upon the secondary surface. These transfers are then turned over upon the primary surface, which is thereupon developed, so as to be capable of printing. The secondary surface has imparted to it from the primary surface this pluralityof designs in the same identical mutual relation. To accomplish this result, I may bring the primary printing-surface and the secondary surface into direct contact, or, as is preferred, I may impart the designs of the primary surface to a conveying-surface, from which the designs are then imparted to the secondary surface. Thus it will be seen the secondary surface has imparted to it a IOO IIO

mined mutual relationand from a unitary plurality of designs in accurate predetersurface bearing said designs in the same identical relation, theprimary surface or the conveying-surface being a unitary basic surface with vrespect to the secondary surface.

The general procedure and the various detailsfollowed in practically carrying out the .VIS

steps of the process will hereinafter more particularly appear in connection with the description of the mechanism shown in the accompanying drawings.

In the drawings forming part of this specication I have illustrated a complete machine capable ofv economically and readily carrying out. the various steps of the process above de- Y scribed.` Ihave also'illustrated several modiications of mechanism.diagrammatically for the purposeof indicating generally thatthe invention is not confined to any particular and specific form of machneor mechanism.

Of the-various types of machines Withwhich my process in itsl broadest aspect may be carried out I prefer to employ the completeorganized machine shown in Figs. 1 to 20,iin elusive. In' this type there are primary and secondary surfaces and a conveying-surface. The machine-is organized with special reference vto securing the desired manipulation and coperation of these three elementsthat is to say, there is mechanism for bringing the primary surface and vconveying-,surface into coperating contact andmechanism for bringing the conveying-surface and secondary surface into coperating contact, such mechanism being preferably arrangedwith a View to securing the required register when the secondary surface comes tobe usedl as a printingsurface. Inasmuch as a primary surface and a secondary surface, with or without a' conveying-surface, have never'heretofore, so far as I am aware, been associated in a definite and predetermined coperatin g relationship both longitudinally and transrversely with reference to prestablished guides, so as to cooperate for the purpose of making a secondary printing-surface and locating the design thereon in a definite predeterminedposition and with reference to register, it will be seen that the process may be carried out by various types of machines or apparatus. e

In practicing the process in its most advantageous form the secondary surfaces are cylindrical and preferably are shell-like and tulbular and made removable from rotary supessary to insure that they are made to occupy their prestablished seats on their supports. This the invention provides for. r

I will now describe the process in its various details by specificall y describing the particular machine shown in the drawings, omitting generally from' such description for the sake of clearness further statements designed IIO to indicate what are and what are not the essentials of the invention in its more or less generic aspect. K

1 is the primary surface, cylindrical in form and preferably shell-like and continuous and Vremovable from its supporting-cylinder 2,

which is secured on the shaft 3, turning in boxes 4. This primary surface is suitably developed and when inked is ready to print the design which it is desired to carry over and impart to the cylindrical secondary surface 5 on the support 6, secured on the shaft 7, which turns in the boxes 8. The secondary surface 5 is also preferably continuous and removable from its support.

In Figs. 28 and 29 is shown the preferred arrangement for the secondary surface. The secondary surface is there shown as a continuous cylindrical shell-like tube with a seamless exterior. The secondary surface has a cylindrical support 6, the former having a slight interior taper and the latter a corresponding exterior taper, so that the secondary surface may be easily removed from its support, which contacts with and firmly supports every point of the internal periphery of the secondary surface. In order that the secondary surface 5 may be readily mounted always exactly in its predetermined seat on its support 6, suitable guiding means for this purpose are provided, which insure absolute identity and accuracy of position at all times both longitudinally and circumferentially. The guiding means for circumferential location shown in the drawings consists of two opposite longitudinal grooves 220 and 221, accurately cut on the exterior surface of the supporting-cylinder 6, and corresponding ribs 222 and 223, formed on the interior of the secondary surface and adapted to slide and accurately fit in these grooves, a marked rib of the secondary surface in a marked groove of the support. For the purpose of insuring identity and accuracy in the longitudinal position of the secondary surface on its support the support' is provided with a collar 224, screwed on one end of the support to form a fixedabutment, against which one end of the secondary surface accurately ts when in place on its support. The secondary form is locked in place against any accidental longitudinal movement by the clamps 225 and screws 226 on the opposite end of the support. The support 6 is generally provided at one end, on which the collar 8 is fixed, with ascrew 227, extending through a nut 228, adapted to travel to and fro on the screw in the slot 229 in the support 6 and arranged to start the secondary surfacefrom its seat by the rotation of the screw. If desired, the support 6 may be so constructed as to be removable from its shaft 7, the support being seated on the shaft against the collar 230 by keys 231 entering slots 232 in the shaft, and, if required, the secondary surface may be fixed permanently on its support, the collar 230 and the keys 231 serving as guiding means whereby the removable support may be accurately located both longitudinally and transversely in a predetermined position on the shaft. It is preferred, however, to make the secondary surface removable from the support 6. The primary surface is preferably arranged and constructed in the same way.

9 is a shaft turning in boxes 10 and carrying the drum or support 11 for the conveying-surface 12, adapted to receive an imprint from the primary surface 1 and carry it over or impart it to the secondary surface 5.

The inking-frame 13, carrying the inking- Vrollers for the primary surface 1, is fixed on the shaft 15, so as to be swung thereby to and from the primary surface. On the opposite side of the machine and fixed on the shaft 16 is the inking-frame 17, carrying the inkingrollers for the secondary surface 5. The frames 14 and 18 for the damping-rollers for the respective printing-surfaces are loosely mounted on the shafts 15 and 16, respectively, so as to turn thereon when moved to and from their printing-surfaces, as will hereinafter more fully appear. The inking and damping frames and rollers for the primary andsecondary surfaces 1 and 5 are similar and similarly mounted and actuated. Their details will be described later on. Q

The main driving-shaft 19 of the machine is actuated from any suitable source of power, as the electric motor 20, and carries the fixed gear 21, which meshes with the gear 22,fixed on the shaft 23, which may be called the power-distributing7 shaft, because the power for driving the primary and secondary and conveying surfaces and inking and damping rollers is derived from this shaft 23. For the purpose of this distribution of power the shaft 23 is provided with suitable clutches 24 and 25. The clutches 24 and 25 are operated, respectively, by the clutch- shafts 27 and 28, provided with hand- levers 29 and 30. The clutches 24 and 25 make fixed and loose the gears 3l and 32, respectively, on the shaft 23. The shaft 23 is carried in brackets 26, xed on the main frame. (See Fig. 2.) The gears 31 and 32 mesh, respectively, with the gears 33 and 34, fixed on the short shafts 35 and 36, supported by the main frame and the brackets 37 and 38, respectively. The shaft 36 has fixed thereon gears 39 and 40, the former meshing with gear 41, which is loose on the shaft 16, and meshes with idle gear 42, meshing with gear 43, fixed on the shaft 7, which carries the secondary surface 5. The gear 40 meshes with gear 44, secured to the main ink-distributing cylinder 45, which is sleeved to rotate on the shaft 16. The short shaft 35 on the opposite side of the machine from shaft 36 has fixed thereon the gears 46 and 47. The gear 46 meshes with the gear 48, which is loose on the shaft 15, and meshes with the idle gear 49, which meshes with the gear 50, fixed on the shaft 3, which carries the primary surface 1. The gear 47 meshes IOO IIO

`with the gear 51, which is secured to the mainl inking-cylindcr 52, sleeved kto rotate on the shaft 15. It will thus be seen that byA operating the clutch 25 to lock the gear 32 onthe face.

yshaft 23 the secondary surface is driven through the train of gears 32, 34, 39,41, 42, and 43 and Vthat the inking-cylinder 45 is likewise driven through thetrain of gears 32,A

34, 40, and 44. It will likewise be seen that by operating the clutch 24 to lock the gear 29 on the shaft 23 the primary surface 1s drivenV through the train of gearing 31,33, 46, 48,

49, and and that the inking-cylinder 52 ing-roller 59, which supplies the form-damp-l ing rollers and 61. Thus it will appear that these'inkingand damping rollers are driven with the secondary surface 5 to supply that surface with inkand water as may be required in developing said surface into a printing-sur- On the opposite side of the machine i the inking and dampeni ng rollers are similarly arranged and geared. The ink-distributing roller 62 carries a gear 63, which meshes with the gear 51 and with a gear on the reciprocating inking-roller 64, which supplies the rollers 65 and 66. meshes with the gear 51 and with a gear on the water-roller 68, which supplies water to the An idle gear 67 on the frame 14l 3 rotates. By turning the eccentrics the `sl1aft,-vs'fi`thits printing-surface, is -moved laterally. Vertical vadjustment may' also be obtained by these eccentrics. They have slots 93`and bolts 94 to lock the eccentrics in their adjusted positions. The boxes 8 of the shaft 7 rare similarlyprovided with adjusting means. In order that the supports of cylinlders 2 and 6 may be lifted'from place in the machine orlowered into position, I provide pairs of lifting-arms for each cylinderj2 and 6. The lifting-arms 96 for the cylinder 2are provided with forks 97 at their upper ends to engage and supportthe shaft3 and at'their lower ends areprovided with racks V98. The lifting-arms 99 for the cylinder 6 `are similarly constructed and arranged. y provided with the loose worms 100`and 101, adapted to be located thereon by means of theclutches102 and 103, operated by the levers 104 and 105, respectively. These'worms 100 Vand 101 engage worm-gears 106 and 4107 on Vthe shafts 108 vand 109, respectively, which carry two gears 110 and two gears 111.` The gears 110 mesh with the racks of the arms 96, and the gears 111 mesh with the racks of the arms 99. vBy these means the lifting-arms are hoisted and lowered to facilitate the lowering of the cylinders 2 and 6 vto place or to facilitate the removal of these cylinders from place.

I will now describe the mechanism for operating thel support or cylinderll.

rollers 69 and UJ The 1n king and dampening rollers for the primary/surface are for the purpos'e of supplying that surface with ink and water, so that it may print the design thereof as required. When the inking and dampening rollers are not required, they are swung back from their printing-surfaces, but these surfaces may still be driven by the idle gears 42 and 49. The inking-frames 13 and 17 are swung back by the worm-shafts 71 and 72, respectively, having the hand-wheels'73 and 74.

These worm-shafts actuate the worm-wheels.

and 76, fixed on the shafts 15 and 16, on which the inking frames are respectively fixed. The dampening-frames 14 and 18, carrying their water-rollers, are swung back,

from their printing-surfaces when. not required by the crank-shafts 77 and 78, carrying, respectively, the cranks 79 and '80,con-

nected `with their frames by links 81 and 82. The crank-shafts are driven by the gears 83 and 84, fixed thereon and actuated, respectively, by gears and 86, operated by the j The boxes 4for the shaft 3 are adjusted vertically in their re- A cesses in the main frame by the lower screws 89 and the upper screws 90, the latter working ,through arms 91, pivoted on the main frame, so that they may be swung aside when the-boxes are to be lifted from place.

For the purpose of lateral adjustment I provide eccentrics 92 in the boxes 4, in which the shaft on which is mounted the loosegear 115, meshing with the gear 116, fixed to the cylinder 11. A clutch 117, operated by they rods 118, which are actuated by the lever 119, serves to lock 'the loose wheel 115 on its shaft when the cylinder 11 is to be rotated.

I will now describe the mechanism whereby the cylinder 11 is moved to andfrom the `cylinders 2 and 6 for the purpose of receiving an impression on its conveying-surface 12 fromthe primary surface 1 and carrying it over to the secondary surface 5.

The boxes 10, (see Figs. 11, 12', 13, and 14,) which support the shaft 9 of the cylinder 11, are capable of lateral movement in their recesses. Keyed on the ends of the shaft 9 and outside the Vframe are the eccentrics 120, `working in the vertically-moving boxes 121. Fast on the shaft 9, near one end, is the gear- 'wheel 122, in mesh with which is the gear 123 on the shaft 124, turned by the hand-wheel 125. By turning the hand-wheel125 the shaft 91s rotated and with it the eccentrics 120, whichas they turn force the boxes 10 in a lateral direction. The eccentric-boxes 121 move slightly vertically in correspondence withthe movement of the eccentrics. This mechanism is capable not only of moving the conveying-surface into contact with the primary and secondary surfaces, but'also of applying to such contact allthe pressure required. Y

The shaft 19 is IOO will now describe the details of the inking and dampening frames. (See Figs. 7, 8, 9, and 10.)

The inking-frame 17 is provided with the bosses 126 to receive the shaft 16, which carries the main ink-distributing roller 45 and on which the frame is fixed, as already described. The rider-roller 53 is carried in boxes 127, supported in recesses 128. The reciprocating rider 55 is also supported in recess 129. These recesses 128 and 129 are open at their outer sides and are closed by the arms 130, pivoted on the main part of the` inking-frame by the bolts 131 and locked in place by the nuts 132 on the bolts 133, which pass through aperturesin the lower ends of these arms. When it is desired to take the rollers 53 and 55 out of the frame for the purpose of cleaning them'or otherwise, the arms 130 are nnfastened and swung back, and the rollers may then be removed. The boxes 127 are adjusted by the inner screws 134, having lock-nuts, and outer screws 135. The screws 135 pass through threaded apertures in the arms 130, are provided with lock-nuts 136 and hand-wheels 137, and have heads 163, which rest in slots 164 in the inner sides of the boxes 127. Pivoted on the bolts 138 and preferably on the upper ends of the arms 130 are arms 139, having forks 140 at their lower ends engaging grooves 141 on the hand-wheels 137.

The outer adjusting-screws 142 pass through threaded apertures in the arms 139 and loosely through apertures in the arms 130. These screws have also lock-nuts 143. 144 are the inner adjusting-screws for the roller 55 and have lock-nuts, as shown. The rollers 53 and 55 are iirstset by their adjusting-screws; but when it becomes necessary to temporarily separatevthese rollers from the form-inking rollers 56 and 57, as when the machine is stopped for an hour or so, the hand-wheels 137 are turned, and the rollers 53 and 55 thereupon separate from the inking- rollers 56 and 57. These rollers 56 and 57 are supported in the recesses 147 and 148, respectively, open at their outer ends. These recesses are closed by the arms 149, pivoted by the bolts 150 on the main part of the frame 17 and locked in place by the bolts 151 and nuts 152. The outer adj usting-screws 153 and 154 for these rollers pass through threaded apertures in the arms 149 and have lock-nuts, as shown. 155 and 156 are the inner adjusting-screws for the rollers 56 and 57 and also have lock-nuts. When the rollers 56 and 57 are to be removed, as for the purpose of washing them or othery wise, the arms 149 are unlocked and swung back, when the rollers may be withdrawn. 157 is a lever pivoted on a bracket 158 and operating to reciprocate the roller 55. This lever has a lug 159 engaging an actuatingcam 160, rotating with the roller 45 on the shaft 16, (see Fig. 4,) and also has a lug 161 engaging a groove 162 in the roller 55. The inking-frame 13 and its rollers is a duplicate of the frame 17 and its rollers.

The dampening-frame 18 (see Figs. 9 and 10) is provided with bearings 165 to receive the shaft 16, on which, as already described, the frame is pivoted. The dampening-roller 59 is carried in boxes 166, which fit in recesses 167, in which they are adjustable by the inner screws 168, having lock-nuts, and by the outer screws 169, having lock-nuts and handwheels 170. The screws 169 have heads 171, which work in recesses on the inner sides of the boxes 166. The roller 59 has a gear 172, meshing with the idle gear 58, carried by the frame 18, whereby the dampening-rollers are driven. The roller 59 may be withdrawn from its boxes by retracting the journal at one end, which may be slid into a recess in thel roller by moving the pin 173 backward in its slot. The form-dampening rollers apd 61 are carried in recesses 174 and 175, respectively, open on their outer sides, which are closed by the arms 176, pivoted to the frame 18 by bolts 177. Bolts 178, passing through apertures in the free ends of these arms, serve, with their nuts 179, to lock the arms in place. These rollers are adjustable and heldin place by the outer screws 180 and 181, respectively, havinglock-nuts and passing through threaded apertures in the arms 176, and by the inner screws 182 and 183, having lock-nuts. When it is desired to remove the rollers 60 and 61, as for cleaning, the arms 176 are swung back, when the rollers may be withdrawn from the frame.

I will now describe the specic construction of the supportwhich carries the conveying-surface 12. This support is shown in the drawings as acylinder 11 and provided with various accessories adopted for convenience. It will be understood that this support or cylinder and its accessories may be variously modified and still carry out the main purpose of carrying over an imprint or impression from the primary surface to the secondary surface. The cylinder is loosely mounted on the shaft 9, carried by the `boxes 10, which are supported by the main frame between the primary and secondary surfaces, as already described. On the shaft 184 is carried a roll of a suitable fabric, constituting the conveying-surface 12,and preferably transfer-paper. The shaft 184 is journaled in two extensible arms 185, provided with racks 186, telescoping with the arms 187 on the bosses 188, loose on the shaft 9. A shaft 189, having gears 190 at both ends, which mesh with the racks 186, serves when rotated by its hand-wheel to move the arms 185, so as to carry the rollin and out of the recess 191, formed in the cylinder, the arms 185 being locked either in or out by the spring-latch 192. The bosses 188 have gear-teeth 193, meshing with the gears 194, fixed on the shaft 195, whereby the arms 185 and 187 may, when the roll is drawn out of its recess 191, be moved around the periphery of the cylinder 11, so that the end of the paper maybe caught by the gripper-s 196, carried by the rod 197 against an arm 214, on
